How much time do I actually have?
You can usually apply to remortgage up to 6 months before your current rate ends. Most UK lenders honour the offer for 6 months, and if rates fall in the meantime you can normally switch to a lower deal before completion. Even with just a few weeks left, a new mortgage is almost always possible.
| Time remaining on your fix | Typical options | Risk of SVR |
|---|---|---|
| 6 months | Full market access — lock a rate, downgrade later if rates fall | Very low |
| 3 months | Full market access — comfortable timeline | Low |
| 1 month | Possible — product transfer often the fastest route | Moderate |
| 7–14 days | Product transfer recommended — full remortgage will overrun | High |
| After expiry | Switch from SVR onto a new fixed rate at any time | Currently on SVR |
What happens if I don't remortgage in time?
Your lender automatically moves you onto their Standard Variable Rate (SVR) the day your fixed term ends. SVRs in 2026 typically sit between 7.5% and 8.5% — significantly higher than current fixed deals around 4%. On a £200,000 mortgage that's roughly £400–£500 extra per month.
The good news: SVR is a temporary fallback, not a trap. You can apply to remortgage from SVR at any time, with no Early Repayment Charge. Your credit file is not affected provided you keep making the higher monthly payment.

Why might I struggle to remortgage before my rate ends?
Most urgent remortgage cases fall into one of a handful of patterns. In nearly every case there is a lender — somewhere on the 90+ lender panel — who will consider the application. The challenge is finding them quickly.
My income has changed
A pay rise is rarely a problem. A pay cut, drop in commission, or a switch from PAYE to self-employed limits choice but does not close the door. Specialist lenders use different income calculations — for example, treating the latest year of self-employed accounts on its own rather than averaging two years.
I'm self-employed
Self-employed remortgages are routine. Several mainstream lenders accept 1 year of accounts, and contractors can often borrow against a day rate × weeks worked. The paperwork is heavier but the timeline is similar.
My credit score has worsened
Defaults, CCJs and missed payments narrow your lender list but specialist lenders price for these specifically. Check your file with Checkmyfile first so we can target the right lenders straight away. See our guide on improving your credit score.
My property value has fallen
If your loan-to-value (LTV) has crossed a band — for example moving from 75% to 80% — the rate available will be slightly higher. A product transfer with your existing lender usually preserves your current LTV band, which can be the cheapest urgent option.
My lender has declined me
Decisions vary enormously between lenders. Being declined by your current bank is not a decline by all 90+ on the market. Different lenders weight income, credit history, age and property type very differently.
I left it too late
You haven't. Even a remortgage started 2 weeks before expiry will usually complete — the worst case is a few weeks on SVR, costing a few hundred pounds, while the new rate locks in years of savings.
How can I remortgage quickly? (Fast-track process)
The 7-step urgent remortgage process we run for clients in a hurry:
- Check your expiry date — find the exact date on your annual statement or app.
- Gather documents — ID, 3 months' payslips, 3 months' bank statements, current mortgage statement, buildings insurance.
- Get a product transfer quote from your existing lender as your benchmark and fallback.
- Compare the whole market — we check 90+ lenders for a better deal after fees.
- Submit the application — most lenders decide within 48 hours.
- Valuation & offer — most cases use an automated valuation; offer in 1–3 weeks.
- Completion — conveyancing 2–4 weeks; new rate starts the day after your current deal ends if timed correctly.
Can I switch to a product transfer instead?
Yes — and it's often the fastest option. A product transfer keeps you with your existing lender but moves you onto one of their current deals. There's usually no new affordability check, no valuation and no legal work. Many product transfers complete in 7–14 days.
The trade-off: you only see your current lender's rates, not the whole market. We always compare both, so you never leave money on the table.
