Junior Software Engineer Salary UK 2026/27
ONS does not measure junior roles separately, so the honest anchor is where juniors sit within their unit group. For programmers and software development professionals (SOC 2020 2134) the lower quartile was £42,289 in ASHE 2025 and the 10th percentile £32,835, against a group median of £56,914 that includes engineers at every level of experience.

What influences junior software engineer pay
The figures here are percentiles of the whole software development occupation, not a measurement of junior roles. ONS publishes by occupation rather than by seniority, so a junior is described by the bottom of the group rather than by a separate median.
Employer type moves entry pay more than anything else. The same group contains public sector digital roles and venture-funded companies competing with each other rather than with the UK average, which is why the 10th percentile and the median are £24,079 apart.
Where an employer offers pension contributions by salary sacrifice, a basic-rate taxpayer saves 20% Income Tax and 8% National Insurance on the contribution. That NI saving is the part people miss: it does not exist in a net pay arrangement like the NHS or Teachers schemes, or under relief at source.

Frequently asked questions
- What do junior engineers actually take home at £35,000 gross 2026/27?
- At £35,000 with a 5% salary-sacrifice pension, take-home is about £27,460 a year, after £4,136 Income Tax, £1,654 National Insurance and the £1,750 contribution. Paying the same 5% under relief at source leaves slightly less, because relief at source gives back the Income Tax on the contribution but not the National Insurance.
- Do US tech companies pay RSUs that are taxed differently in the UK?
- Yes - UK Restricted Stock Units vest and are taxed as employment income at vest time, reported through payroll. They attract Income Tax and NI at your marginal rate. Any subsequent growth is Capital Gains on eventual sale.
