Frequently asked questions
Why am I facing a payment shock now?
UK mortgage rates 2020-2022 were exceptionally low: 1.3-2% for 2-5 year fixed deals. The Bank of England base rate rose from 0.1% in December 2021 to 5.25% by August 2023 (now around 4.25-4.75% in mid-2026). 2-year fixes from 2023-2024 expire 2025-2026; 5-year fixes from 2020-2021 expire 2025-2026. Current remortgage market rates: 4.0-5.5% for typical residential mortgages. Effect on £250k loan: roughly £300-£400/month increase. Estimated 1.5m UK households face material payment shock 2025-2026 as fixed deals expire.
What are my main options when fixing ends?
(a) Remortgage to new fixed rate - 2/3/5-year fixes available, locks predictability. Most common choice. (b) Remortgage to tracker (Bank Rate + margin) - lower initial rate often, but variable. Bet on rates falling. (c) Move to Standard Variable Rate (SVR) - DEFAULT if you do nothing. Typically expensive (~6-8% in 2026). Avoid except temporarily. (d) Product transfer (PT) - new deal with existing lender; usually faster + cheaper than full remortgage. (e) Extend term - longer loan = lower monthly payment. (f) Switch to interest-only temporarily - drastic but FCA Mortgage Charter allows 6 months max. (g) Overpay if you have spare cash to reduce balance before remortgaging.
When should I start the remortgage process?
6 months before your current deal ends. Why early: (a) rate lock-in - many lenders honour current rates for 3-6 months ahead. (b) gives time to research options + use mortgage broker. (c) avoids panicked decisions. (d) Buying-power check - your current valuations + income still relevant for 6+ months. Standard process: month -6 to -4: explore rates via comparison sites + broker; month -3: formal application + valuation; month -1: completion + product activation. Use a fee-free broker (London + Country, Habito) - they get commission from lender, no upfront cost to you.
What is the Mortgage Charter?
FCA + lender-government agreement (June 2023). Voluntary commitments by major UK lenders covering ~90% of UK mortgages. Key provisions: (a) Switch to interest-only for 6 months without impacting credit score, (b) Extend mortgage term (e.g. 25 → 35 years) with right to reverse within 6 months, no credit score impact, (c) No repossession in first 12 months of missing payments, (d) "Tailored support" for those at risk - reduced payments, payment holidays, restructuring. Charter is VOLUNTARY but most major UK lenders signed (Lloyds, NatWest, HSBC, Barclays, Nationwide etc.). Contact your lender ASAP if struggling - don't default first.
Should I fix or take a tracker?
Depends on view of future rates + risk tolerance. Fix (2/5 year): predictable payment, easier budgeting, lose if rates fall significantly. Tracker (often Bank Rate + 0.5-1%): lower initial rate typically, win if BoE cuts rates, lose if rates rise. As of mid-2026, BoE base rate ~4.25-4.75%; consensus forecasts gradually falling to 3.5-4% by end-2027. If you believe rates will fall: tracker. If predictability matters more: fix. Hybrid: 2-year fix while expecting rates to fall, switching to tracker later. 5-year fix at 4.5% reasonable hedge against unexpected rate spikes. No "right" answer - depends on personal circumstances.
Can I extend my mortgage term?
Yes - and many people do to reduce monthly payment. Effect of extending term: 25-year to 35-year on £250k loan at 4.5%: monthly payment £1,390 → £1,180 (£210/mo saving). But TOTAL interest paid increases £166k → £246k (£80k more over loan life). Mortgage Charter allows term extension with right to reverse within 6 months without credit impact. After 6 months, reverse requires affordability check. Strategy: extend term now to manage cash flow, overpay when affordable to reduce balance faster. Many lenders allow 10% overpayment/year without penalty even during fix.
What if I can't afford the new payment?
Action sequence: (1) Contact lender FIRST - before missing payment. Mortgage Charter solutions: 6-month interest-only, term extension, restructuring. Doesn't affect credit score. (2) Check benefit entitlement - if income dropped + you qualify, UC housing element + Support for Mortgage Interest (SMI) loan available. SMI is a loan (not grant) at base rate - covers up to first £200k mortgage interest after 3 months on UC. (3) Budget review - cut discretionary spending; renegotiate energy + broadband + insurance. (4) Income increase - lodger (Rent-a-Room £7.5k tax-free), part-time work. (5) Last resort: downsize or sell. Don't default - voluntary action protects credit score + gives options.

Should I overpay before remortgaging?
Often yes. Reducing balance before remortgage gives you: (a) Lower LTV (loan-to-value) ratio, potentially qualifying for better rate (e.g. moving from 80% to 75% LTV typically saves 0.1-0.3% on rate), (b) Lower future monthly payment at any rate, (c) Reduced overall interest over remaining term. Most lenders allow 10% overpayment of original loan balance per year without Early Repayment Charge. Strategy: maximise overpayment in final year of fix, then remortgage to better LTV band. Calculate ROI: overpayment vs alternative use (pension contribution, ISA savings, debt elimination). Mortgage overpayment guaranteed return = your mortgage rate; usually 4-5% in 2026. Often beats Cash ISA + matches Personal Pension match.
