UK Glazier Salary 2026/27
Apprentice pay through NVQ Level 3 Fenestration Installation, domestic UPVC and aluminium replacement through structural curtain wall, fire-rated and heritage stained-glass day rates, employed vs self-employed take-home, CIS sub-contractor deductions, FENSA and CERTASS Competent Person Scheme registration, capital allowances on the van, suction lifters and rail cutters, and when to switch to a Limited company.
Overview of UK glazier pay
UK glazing sits within ONS SOC 2020 code 5316 ("Glaziers, window fabricators and fitters") with a median full-time gross of around £30,000 to £34,000 in the 2024 ASHE release. The headline figure understates the upper end of the trade meaningfully: GGF-accredited structural curtain-wall specialists, frameless-glass installers working to CWCT Standard for Systemised Building Envelopes, ICON-accredited heritage and stained-glass conservators, and Ltd-company sub-contractor gang leaders routinely earn £75,000 to £100,000+ on a self-employed basis. The ASHE median is dragged down by apprentices and improvers in the bottom quartile and by domestic UPVC replacement work in the middle quartile, where margins are compressed by national chain pricing (Anglian, Everest, Safestyle, Eurocell franchises) and double-glazing aggregator lead-generation costs.
Around 40% to 55% of UK glaziers are self-employed sole traders, sub-contracted to main contractors, double-glazing firms and shopfitters - lower than tiling, bricklaying or roofing because FENSA or CERTASS Competent Person Scheme registration for domestic replacement work is most commonly held at the firm level rather than the individual installer level. The pay structure splits across five distinct work types: domestic UPVC and aluminium window and door replacement (the highest-volume, lowest-margin segment), shop-front and commercial aluminium glazing, structural curtain wall and frameless glass (silicone-bonded structural glazing to CWCT standards), heritage and stained-glass restoration (listed building and ecclesiastical), and emergency boarding and 24-hour re-glazing (insurance-panel and shop-front break-in response with on-call premiums).
The single biggest pay driver above NVQ Level 2 is specialism. Structural curtain-wall glazing (frameless glass walls, atrium roofs, balustrade and balcony glazing, silicone-bonded structural glazing on high-end residential and commercial projects) commands day rates £100 to £200 above general domestic replacement, and most of that premium flows straight to net profit because chargeable time on a curtain-wall job is similar to time on a standard refit. GGF Member Standards listing is the de facto premium credential for the high end of the market. Heritage and stained-glass conservators (ICON-accredited or working under conservation officer briefs on listed buildings and ecclesiastical glass) sit close behind. Geographic premium is significant too: London and the South East add 20% to 30%, driven by both higher cost of living and the concentration of premium residential, commercial curtain-wall and listed-building restoration work in central London and the home counties. CSCS card holding is effectively mandatory for any commercial site access.
Qualifications, accreditation and specialisms
The standard entry route is the Fenestration Installer or Glazier apprenticeship standard under CITB, a 2 to 3 year programme run jointly by an employer and a training provider (typically a further-education college or a private trade school under the CITB framework). The apprentice spends roughly 4 days a week on site and 1 day at college, completes coursework portfolios, and earns NVQ Level 2 Fenestration Installation. NVQ Level 3 is the senior progression qualification and is increasingly expected for gang leaders, structural curtain-wall and heritage glazing work, and complex fire-rated or security glazing installations.
The financial maths of the apprenticeship route is hard to beat. Apprentice National Minimum Wage is currently £7.55 an hour for the first year (or under-19s), rising to age-banded NMW thereafter. A 16-year-old apprentice in year one earns around £8,500 to £14,000 a year; by year 3 most apprentices are on £14,000 to £25,000. Training itself is fully funded by the employer through the Apprenticeship Levy: there are no tuition fees and no student loans. The contrast with the college-only route is stark: a private NVQ-aligned glazing diploma costs £3,000 to £6,000 per year for 2 to 3 years, with no income during study, and you still need an employer placement to log NVQ portfolio units on real installations.
After NVQ Level 2 / 3, the pay-driving credentials are CSCS card holding, FENSA or CERTASS Competent Person Scheme registration, and GGF Member Standards listing. CSCS cards are issued by the Construction Skills Certification Scheme - administered by CITB - and require a Health, Safety & Environment test pass plus evidence of the relevant NVQ. Cards run Green Labourer, Red Apprentice / Trainee, Blue Skilled Worker (NVQ Level 2), Gold Skilled Worker (NVQ Level 3) and Black Manager / Supervisor. Almost every main contractor and large house-builder requires a card before site access. FENSA (Fenestration Self-Assessment Scheme) and CERTASS are the two main Competent Person Schemes for replacement windows and doors in dwellings - registration lets you self-certify Building Regulations compliance instead of going through Building Control approval on every job, and is essentially mandatory for any direct-to-homeowner replacement window business. The GGF (Glass and Glazing Federation) Member Standards programme is the industry quality benchmark for high-end residential and commercial work. SSSTS (Site Supervisor Safety Training Scheme) and SMSTS (Site Manager Safety Training Scheme) are the step-up tickets for Foreman and supervisor roles.
Specialism layers on top of the base qualifications. The five major specialist routes are: domestic UPVC and aluminium replacement (the volume retail-replacement track, NVQ Level 2 Fenestration Installation, FENSA / CERTASS registration mandatory, typical day rates £180 to £380); shop-front and commercial aluminium glazing (Schueco, Kawneer, Reynaers system installation on shopfit and commercial fit-out packages, CSCS Gold; day rates £220 to £450 with CIS sub-contract on main-contractor packages); structural curtain wall and frameless glass (silicone-bonded structural glazing to CWCT Standard for Systemised Building Envelopes, frameless glass walls, atrium roofs and balustrade glazing on high-end residential and commercial projects; GGF accreditation strongly preferred; day rates £280 to £550 and often non-CIS direct-to-architect); heritage and stained-glass restoration (listed building consent work, ecclesiastical restoration, period-property leaded-light replication, ICON conservation accreditation preferred; day rates £250 to £500 with similar direct-to-conservation-officer dynamics); and emergency boarding and 24-hour re-glazing (insurance-panel work and shop-front break-in response, rota-based on-call structure with overnight and weekend premiums; day rates £200 to £450 with £80 to £200 call-out uplifts).
Employee pay grades
Employed glazier pay splits regional and London columns, with a step at NVQ Level 2 to NVQ Level 3 reflecting the move from general domestic replacement into structural curtain wall, fire-rated, heritage and stained-glass territory, then a further step into Foreman / glazing site-supervisor territory. Figures below are typical 2025/26 market data from recruiter postings, GGF member sub-contractor rate context, and the latest ONS ASHE SOC 5316 release; individual employers vary by £2,000 to £4,000 either side depending on whether the role is mostly domestic replacement, mostly commercial shop-front, or in high-end structural curtain wall and heritage. Overtime and travel allowances on top of the headline rate are common in commercial fit-out packages where hotel and retail completion dates drive long-day working.
| Experience level | Regional | London & SE | Notes |
|---|---|---|---|
| Apprentice (Year 1) | £8,500 - £14,000 | £11,000 - £16,000 | Apprentice National Minimum Wage for the first year (£7.55 / hr in 2025/26), age-banded NMW thereafter. Around £4 - £5 effective hourly. |
| Apprentice (Year 2-3) | £14,000 - £22,000 | £17,000 - £25,000 | Improver rate at age-banded NMW after NVQ Level 2 Fenestration Installation portfolio work begins. Around £5 - £7 / hr effective with supervised hot / cold cutting, sealant application and frame setting time. |
| NVQ Level 2 Glazier (windows and doors) | £28,000 - £36,000 | £34,000 - £43,000 | Hourly £14 - £18 regional / £18 - £22 London. Domestic UPVC, aluminium and composite window and door installation on replacement and new-build housing - the highest-volume employed role. FENSA or CERTASS Competent Person Scheme registration usually held through the employer. |
| NVQ Level 3 Specialist Glazier | £36,000 - £46,000 | £43,000 - £54,000 | Hourly £18 - £23 regional / £22 - £27 London. Structural curtain wall, frameless glass, fire-rated glazing (Pyrobel, Pyroguard), bullet-resistant and security glazing, or heritage and stained-glass restoration. Often the gang leader on a 2 to 3 glazier crew. |
| Foreman / Glazing Site Supervisor | £50,000 - £63,000 | £60,000 - £72,000 | Site lead on the glazing package, supervising 2 to 4 glazier gangs plus labourers loading out frames and glass. SSSTS or SMSTS site-supervisor ticket required; CITB Black card holder. Commercial fit-out, hotel and office shop-front packages. |

Self-employed day rates by specialism
Self-employed day rates dominate once a glazier has 5+ years experience and either a strong portfolio of direct domestic clients (with their own FENSA or CERTASS registration), steady CIS sub-contractor work with two or three repeat main contractors or shopfitters, or specialist GGF / ICON accreditation in structural or heritage work. The bands below are gross billings per day (labour, before materials mark-up); typical chargeable days per year run 200 to 220 once you allow for quoting, surveying, admin, materials runs and bank holidays. Glazing has a structural emergency component (insurance-panel and shop-front break-in response) that compresses around weather events and crime cycles with corresponding peaks of on-call working.
| Specialism | Regional rate | London rate | Typical annual net |
|---|---|---|---|
| Domestic UPVC and aluminium window and door replacement | £180 - £280 / day | £250 - £380 / day | Around £38,000 - £58,000 net (assumes 200 - 220 chargeable days). FENSA or CERTASS-registered installer working through a registered firm; direct domestic retail replacement market. |
| Shop-front and commercial aluminium glazing | £220 - £340 / day | £300 - £450 / day | Around £48,000 - £75,000 net. CIS sub-contract on commercial fit-outs, retail rollouts, hotel and office refurbishment; non-CIS direct work for SME shopfitters and architects. |
| Structural curtain wall and frameless glass | £280 - £420 / day | £380 - £550 / day | Around £60,000 - £100,000+ net. Specialist niche - silicone-bonded structural glazing to CWCT (Centre for Window and Cladding Technology) Standard for Systemised Building Envelopes; high-end residential, hospitality and commercial fit-outs; minimal pricing pressure. |
| Heritage and stained-glass restoration | £250 - £400 / day | £350 - £500 / day | Around £55,000 - £85,000 net. Specialist conservation niche - listed building consent work, ecclesiastical restoration, period-property leaded-light replication; direct architect, conservation officer and church-warden referrals. |
| Emergency boarding and 24-hour re-glazing | £200 - £350 / day base + £80 - £150 call-out premium | £280 - £450 / day base + £100 - £200 call-out premium | Around £50,000 - £90,000 net depending on insurance and shop-front network coverage. Insurance-panel work, shop-front break-in response, residential storm damage; rota-based on-call structure with overnight and weekend premiums. |

Construction Industry Scheme (CIS) for glaziers
CIS applies to most employed-style sub-contract glazing work for main contractors and large house-builders: commercial shop-front, hotel and leisure refurbishment, retail rollout, office curtain-wall packages, and new-build housing window and door packages where the glazier is labour-only sub-contracted to the principal contractor. The contractor deducts 20% of the labour element (not materials) at source and pays it to HMRC; the glazier reclaims it via Self Assessment. If the sub-contractor is not CIS-registered the deduction rate jumps to 30%. CIS does not apply to direct work for homeowners (replacement windows, single-pane re-glaze, conservatory) or to most heritage and stained-glass restoration commissioned by conservation officers and private clients - those are normal Self Assessment self-employment.
A glazier on a £55,000 gross commercial shop-front contract under CIS has £11,000 deducted at 20% by the main contractor across the year. At Self Assessment, the £41,800 reclaim sits against the actual Income Tax and Class 4 NIC liability on £52,000 of profit (after expenses), typically £10,300 to £10,500, leaving a refund of £500 to £700. The mechanical effect is that CIS over-collects through the year - useful as a forced savings discipline but a cash-flow drag for sole traders carrying van leases, tool finance and material trade-account balances. The Gross Payment Status route (turnover £30,000+ for sole traders, compliance history check by HMRC) eliminates the 20% deduction entirely and is worth applying for as soon as practical for shop-front and commercial-curtain-wall specialists. See the CIS calculator for sub-contractor deduction worked examples.
Capital allowances on the van and glazing equipment
The glazier's van is the single largest capital purchase - typically £18,000 to £30,000 for a 3.5-tonne panel van with internal glass-rack fit-out, frame rails, A-frame glass trolley mounts, ladder rack and roof rack - and qualifies for 100% Annual Investment Allowance in the year of purchase up to the £1m AIA cap. A self-employed glazier on £55,000 of profit buying a £22,000 van saves £22,000 × marginal rate (20% Income Tax + 6% Class 4 = 26% combined) = £5,720 in the year of purchase. Suction lifters (£300 to £1,500), large-format rail cutters and glass cutters (£200 to £800), sealant guns and pump-action gun systems (£50 to £300), glass clamps and trolleys (£150 to £600), laser levels (£200 to £800), portable scaffold towers (£500 to £2,000) and frame trolley systems are also AIA-eligible.
Hand tools, sealant cartridges, gaskets, beading clips, intumescent strip, structural silicone tubes and consumables under £200 are typically deducted as revenue expenses immediately rather than capitalised. The 45p / mile mileage rate for the first 10,000 business miles is sometimes more favourable than full van expense claims for low-mileage glaziers (under 8,000 business miles a year) - calculate both and pick the higher. See the capital allowances calculator for AIA, FYA and writing-down allowance computations on van and equipment purchases.
Career progression worked example
A typical UK glazier career progression takes you from apprentice through NVQ Level 2 employed glazier into self-employed sole trader, then onwards either to structural / heritage specialist (sole trader) or Limited company director with FENSA or CERTASS registration held at the company level. Take-home figures below are engine-verified at 2026/27 thresholds.
| Rank | Gross | Take-home | Marginal rate |
|---|---|---|---|
| Apprentice (Year 1) | £12,000 | £12,000 | Below PA, 0% Income Tax |
| NVQ L2 glazier (regional) | £32,000 | £25,408 | 20% basic rate + 8% NI |
| Self-employed shop-front glazier | £52,000 | £41,471 | 20% IT + 6% Class 4 NIC, edges into 40% band |
| Structural / heritage specialist (sole trader) | £80,000 | £57,711 | 40% IT + 2% Class 4 NIC above UPL £50,270 |
| Ltd co director (salary + dividends) | £85,000 | £65,831 | Salary at 20% / 0% NI band; dividends 8.75% / 33.75% |
Glazier vs tiler, roofer and carpenter
Glaziers, tilers, roofers and carpenters all sit in the £30,000 to £36,000 ASHE median band but the specialism premium and self-employed economics differ meaningfully. Tilers have the most defined m² piecework market - kitchen and bathroom packages on new-build housing are priced per square metre - and the natural-stone / mosaic premium niche is roughly equivalent in scale to the structural-curtain-wall niche for glaziers. Roofers face the most weather-dependent chargeable-day count (loss of 15 to 30 days a year to rain and high winds) and the highest physical-risk profile, but the heritage slate and lead-work specialism commands premium rates. Carpenters have the broadest internal vs external split with a clear cabinet-maker progression that glaziers do not have a direct analogue for. Glazing is distinguished by the FENSA / CERTASS Competent Person Scheme regulatory layer (no direct parallel in the other three trades) and by the 24-hour emergency call-out sub-market with its own on-call rota economics.
Frequently asked questions
How much does a UK glazier earn in 2026/27?
An employed NVQ Level 2 glazier earns around £28,000 to £36,000 a year outside London and £34,000 to £43,000 in London on hourly rates of £14 to £18. An NVQ Level 3 specialist glazier (structural curtain wall, frameless glass, fire-rated, heritage and stained-glass) sits at £36,000 to £46,000 regional / £43,000 to £54,000 London; a Foreman or glazing site supervisor earns £50,000 to £72,000. Self-employed sole traders on domestic UPVC and aluminium replacement typically clear £38,000 to £55,000 net of expenses; GGF-accredited structural curtain-wall and frameless-glass specialists running a busy book of commercial and high-end residential work clear £75,000 to £100,000+.
What qualifications do I need to work as a glazier in the UK?
The standard route is NVQ Level 2 Fenestration Installation (windows and doors) for general domestic and commercial work, and NVQ Level 3 for senior, structural curtain-wall, fire-rated and heritage glazing roles, typically achieved through a 2 to 3 year apprenticeship under the CITB Fenestration Installer or Glazier apprenticeship standard. A CSCS card (Construction Skills Certification Scheme) is mandatory for almost all commercial construction sites. Installing replacement windows or doors in a dwelling additionally requires registration with a Competent Person Scheme (FENSA or CERTASS) - typically held by the employer or your own Limited company rather than by the individual installer. SSSTS or SMSTS site-supervisor tickets are typically expected for Foreman roles.
What is FENSA and CERTASS, and do I need both?
FENSA (Fenestration Self-Assessment Scheme) and CERTASS are the two main Competent Person Schemes in England and Wales for replacement windows and doors in dwellings. Registering with one of them lets you self-certify Building Regulations compliance instead of going through Building Control approval on every job - which would be uneconomical for a £1,500 window replacement. You only need one of the two: FENSA has the larger market share and is more recognised by homeowners, CERTASS is typically cheaper for small firms. Both audit a sample of your installed jobs each year for compliance with Approved Documents L (energy), F (ventilation) and Q (security). Registration is typically held by the firm, not the individual installer, so a self-employed glazier sub-contracting to a registered firm does not need their own registration. A self-employed glazier going direct to homeowners on replacement windows must hold their own registration.
How much can a self-employed glazier actually take home?
A self-employed sole trader glazier with £52,000 of profit (after deducting van, fuel, suction lifters, rail cutters, sealant guns, PPE, glass cassettes, and insurance) keeps about £39,700 after Income Tax and Class 4 National Insurance in 2026/27 - an effective rate of roughly 24%. A structural curtain-wall or heritage-glass specialist on £80,000 profit keeps about £55,100 after the higher-rate band and Class 4 NIC at 6% / 2%. Limited company structures save more above £50,000 of annual profit, especially once profits start pressing on the £100,000 Personal Allowance taper.
Does CIS (Construction Industry Scheme) apply to glaziers?
CIS applies to most employed-style sub-contract glazing work for main contractors and large house-builders - commercial fit-outs, hotel and leisure refurbishment, shop-front packages, new-build housing window and door packages where you are a labour-only sub-contractor billing the principal contractor. The contractor deducts 20% of your labour (not materials) at source and pays it to HMRC; you reclaim it via Self Assessment. If you are not CIS-registered the rate jumps to 30%. CIS does not apply to direct work for homeowners (domestic window or door replacement, conservatory glazing, single-pane re-glaze) or to most heritage and stained-glass restoration commissioned by conservation officers and private clients. Commercial shop-front glaziers are almost always inside CIS; domestic-replacement and heritage specialists working direct often are not.
Should I go limited company or stay sole trader as a glazier?
Limited company becomes tax-efficient above roughly £45,000 to £50,000 of annual profit. The director takes a £12,570 salary (uses Personal Allowance, no NI), the company pays Corporation Tax at 19% to 25% on the rest, and the remainder is paid as dividends taxed at 8.75% / 33.75% with a £500 dividend allowance. A director on £35,000 salary + £50,000 dividends takes home around 10% to 14% more than a sole trader on £85,000 profit once you net off Corporation Tax, but you incur accountancy fees of £900 to £1,800 a year and run more admin. Limited structure is also the natural vehicle for holding FENSA or CERTASS Competent Person Scheme registration directly - useful for direct-to-homeowner replacement window work. The structure works best for structural curtain-wall specialists, heritage and stained-glass practitioners, emergency boarding and 24-hour re-glazing firms with several vans, and gang-leader glaziers with consistent £60k+ annual profit.
What expenses can a self-employed glazier deduct?
Allowable expenses include van running costs (fuel, insurance, MOT, repairs - or HMRC mileage at 45p per mile for first 10,000), hand tools and consumables (immediately deductible as revenue expenses if under £200, otherwise via Annual Investment Allowance), cut-resistant gloves and PPE (revenue), glass, sealed units, beading, gaskets, structural silicone, intumescent strip and fire-rated mastic (cost of sales), workwear and PPE with logo, mobile phone (business proportion), public liability insurance (£5m typical), tools and material in-transit insurance (glass cassettes are high-value high-fragility), GGF membership and CSCS card fees, FENSA or CERTASS Competent Person Scheme annual registration (around £350 to £450 / year), accountancy fees, and use of home as office (£26 a month simplified). The van is a capital allowance: 100% in year one via the AIA up to £1m. Suction lifters (£300 to £1,500), large-format rail cutters and glass cutters (£200 to £800), sealant guns (£50 to £300), glass clamps and trolleys (£150 to £600), laser levels (£200 to £800), and frame trolley systems are also AIA-eligible.
How does the apprenticeship route compare to paying for college?
A glazing apprenticeship is a 2 to 3 year programme under the CITB Fenestration Installer or Glazier apprenticeship standard, typically combining NVQ Level 2 Fenestration Installation and CSCS Blue Skilled Worker card. You earn the apprentice National Minimum Wage in year one (currently £7.55 an hour, around £8,500 to £14,000 a year) and progress to age-banded NMW thereafter, while training is fully employer-funded under the Apprenticeship Levy. The college-only route costs £3,000 to £6,000 per year for an NVQ-aligned glazing diploma, with no income during study and you still need on-site experience to log NVQ portfolio units. For most glaziers under 25, the apprenticeship route is financially better - you finish debt-free with 2 to 3 years of real on-site experience, a CSCS Blue card, and a clear path to NVQ Level 3 with structural, fire-rated or heritage specialism options.
How much do structural-curtain-wall and heritage-glass specialists earn?
Structural curtain-wall glaziers working in silicone-bonded structural glazing to CWCT (Centre for Window and Cladding Technology) Standard for Systemised Building Envelopes - frameless glass walls, atrium roofs, balustrade glazing and prime-residential extensions - command day rates of £280 to £420 regional / £380 to £550 London, well above the general glazier range. Heritage and stained-glass specialists working under listed building consent on ecclesiastical restoration, period-property leaded-light replication and conservation-area refurbishment sit just behind at £250 to £400 regional / £350 to £500 London. Annual gross billings of £75,000 to £100,000+ are achievable for an established specialist on the GGF Member Standards programme working direct to architects, conservation officers and main contractors. The niche has minimal pricing pressure because the work cannot be done by general domestic-replacement glaziers - it requires CWCT structural glazing competence, ICON conservation accreditation for heritage work, or period leaded-light technique.
How does VAT work for self-employed glaziers?
You must register for VAT once your rolling 12-month turnover exceeds the £90,000 threshold. Once registered, you charge 20% VAT on labour and materials. Domestic clients (homeowner replacement windows, conservatory glazing) cannot reclaim it, so the VAT is a real 20% price increase; commercial main contractors reclaim it so VAT registration is largely neutral for B2B sub-contract work. New-build residential housing is zero-rated for VAT, which simplifies the picture for new-build glaziers but requires careful invoicing. Energy-saving materials installed in residential accommodation - which includes most modern double and triple-glazed sealed units that meet the U-value threshold - currently qualify for zero-rated VAT under the temporary policy in place until April 2027, materially improving margins on direct-to-homeowner replacement window work. The Domestic Reverse Charge for construction services (effective March 2021) shifts the VAT accounting on most B2B sub-contract work to the customer rather than the supplier - your invoices to main contractors should be marked accordingly.
