Fixed Rate Mortgage Ending? What Happens Next & Exactly What to Do
1.8 million fixed deals expire in 2026 — and every one of them rolls onto a ~7% variable rate unless its owner acts. Here’s what actually happens when your fix ends, the real cost of doing nothing, and the month-by-month countdown that protects you.
Deal ending in the next six months?
You can lock a new rate today — and still switch if something better appears before your fix ends. A whole-of-market broker sets that up in one conversation, free.

Quick answer
When your fixed rate ends, nothing dramatic happens to the mortgage itself — the balance, term and payments continue — except the one thing that matters: you’re automatically moved onto your lender’s Standard Variable Rate, currently averaging around 7.13% against best-buy fixes of roughly 4.2–4.7%. On a £200,000 balance that gap is worth about £290 a month. Your options: a product transfer with your current lender (fast, no affordability check, limited to their shelf), a full remortgage to a new lender (4–8 weeks, whole market, often the better rate), a tracker if you’re betting on cuts — or doing nothing, which is also a decision and usually the most expensive one. The mechanism that makes this painless: most lenders let you lock a new deal up to six months before your fix ends, timed to start the day it expires (so no early-repayment charge), and if rates fall before then, you can generally still swap to the better deal. Position as of July 2026, with 1.8 million households doing exactly this alongside you.
Your home may be repossessed if you do not keep up repayments on your mortgage.

What happens when your fixed rate mortgage ends
The mechanics are simpler than the anxiety suggests. Your mortgage doesn’t end, mature, or need re-approval — the loan, the remaining term and the repayment method all roll on untouched. What expires is only the rate deal: on the day your fix ends, your lender automatically moves you onto their Standard Variable Rate (SVR) — their default rate, set at their discretion, changeable at any time, and almost always far above the fixed deals on sale (the full SVR mechanics are in our variable rate guide). No paperwork, no warning beyond the letters they’re required to send, no penalty — and crucially, no early-repayment charges once you’re on it, so you’re free to leave whenever you like. The problem isn’t a trap; it’s a meter running at nearly 3% above the market while you get around to things.
The cost of doing nothing — in actual pounds
| £200,000 balance, 25 years left | Monthly payment | vs new fix |
|---|---|---|
| New 5-year fix at ~4.5% | ~£1,112 | — |
| Lender SVR at ~7.13% | ~£1,432 | +£320/month, ~£3,800/year |
And for the 2021–22 cohort whose cheap five-year fixes are expiring now, honesty requires the other table too: the same £200,000 fixed at 1.8% cost about £828 a month — so even the good outcome (a new ~4.5% fix at ~£1,112) is a £280–£300 monthly rise, which is why UK Finance expects around two million households to see jumps of £200–£499 by the end of 2026. The action plan below can’t abolish that adjustment — nothing can — but it reliably decides whether you pay the fix-to-fix rise or the fix-to-SVR one, roughly double. If the rise threatens the budget rather than merely annoying it, the unaffordable section below is written for you.
How soon can you remortgage before your fixed rate ends?
Up to six months early — and you should. Most lenders let you secure a new deal three to six months before your current fix expires (“rate reservation”), with the new deal timed to begin the day the old one ends — so no early-repayment charge is triggered, because you never actually leave the fix early; you just have the replacement waiting. Two features make the six-month lock close to a free option: if rates rise after you lock, you keep your reserved rate; if they fall, most lenders and brokers will let you swap to the better deal before completion — lock-then-review is the standard 2026 play, and with the Bank of England forecast to keep easing gradually, it matters this year especially. A full remortgage takes 4–8 weeks to arrange, which is exactly why starting at the six-month mark (not the six-week mark) is the difference between a seamless switch and a couple of expensive months on the SVR. For the deeper strategy questions — remortgaging mid-fix despite ERCs, fix-length choice, timing against rate forecasts — our when to remortgage guide is the authority; this page assumes the simpler, commoner case: your deal is ending, and you want the handover clean.

Your four options, compared honestly
| Product transfer (stay put) | Remortgage (move lender) | |
|---|---|---|
| What it is | New deal from your current lender | New lender entirely |
| Effort & speed | Often online in under an hour; no affordability check, no valuation, no solicitor | Full application: 4–8 weeks, credit check, valuation (usually free), legal work (often free) |
| Choice | One lender’s shelf | The whole market — and if your loan-to-value has improved since you last fixed, a better rate tier may now apply |
| Best when | Your lender’s retention deal is genuinely competitive; your circumstances have got harder to underwrite; time is short | The market beats your lender (it often does); your LTV has improved; you want to change the loan itself |
The third option, a tracker, suits genuine believers in further rate cuts who can stomach payment variability — the trade-offs live in our tracker guide, and fix-length strategy in our fixed rate guide. The fourth option — staying on the SVR deliberately — has exactly one good use: a short, flexible bridge when you’re about to sell, move or repay, since it carries no ERCs. As a passive default it’s the most expensive choice on the page. The genuinely useful move is making the product-transfer-vs-remortgage comparison properly: your lender will show you their shelf; only a whole-of-market broker (typically free) can hold that shelf up against the entire market in one pass.
The countdown: what to do, month by month
- 6 months out — open the file. Find your exact end date and current lender’s SVR (mortgage statement or app). Check your credit report and fix any errors. Gather the document pack — the full list and order of operations is in our application guide — and get the whole-market comparison run against your lender’s transfer offer. Lock the best deal.
- 3–4 months out — application in motion. If remortgaging, the full application goes in now (4–8 week runway). If your circumstances have changed since the last fix — income shape, new commitments — this is when it surfaces and gets solved, not at the deadline. Freeze new credit from here to completion.
- 6–8 weeks out — the review. Rates moved? Have the broker re-check the locked deal against the current market; swap if better. Confirm the new deal’s start date aligns to the day after your fix ends.
- 2 weeks out — confirm the handover. Offer issued, legal work (if any) complete, direct debit details confirmed.
- Day one — the new rate starts, the SVR never happens. Diarise the next expiry immediately — this whole page becomes a calendar entry five years from now.
If the new payments look unaffordable
For some of the 2021 cohort the fix-to-fix rise alone strains the budget, and there’s a real toolkit before anything drastic: lengthening the term cuts the monthly payment (at the cost of total interest — and FCA rules let borrowers extend and then switch back within six months without a new affordability check); talking to your lender early unlocks support options they’re required to offer, including temporary arrangements and, in genuine hardship, ERC waivers — contact before a missed payment keeps your credit file clean and every option open; and if payments have already been missed, the recovery landscape is mapped in our bad-credit hub. What doesn’t help: staying silently on the SVR because a new application feels daunting — the SVR is the most expensive form of avoidance available, and a broker conversation costs nothing and commits you to nothing.
The bottom line
When your fix ends you roll onto an SVR near 7% by default — a ~£300-a-month meter on a typical balance — and the entire defence is calendar discipline: lock a new deal up to six months early (swappable if rates improve), compare your lender’s transfer offer against the whole market rather than accepting the shelf you’re shown, and time the new deal to start the day the old one dies. The 2021-cohort payment rise is real either way; whether it’s the manageable version or the double version is decided entirely by the six-month countdown above.
The most valuable half-hour is the first one: compare mortgage deals and a whole-of-market broker will run your lender’s offer against the market, lock the winner for your switch date, and re-shop it if rates fall — free, no obligation.
Fixed rate ending: FAQs
What happens when my fixed rate mortgage ends?
Your mortgage continues unchanged — same balance, same remaining term — but the expired deal’s rate is replaced automatically by your lender’s Standard Variable Rate, currently averaging around 7.13% versus new fixes at roughly 4.2–4.7%. Nothing requires your signature and nothing penalises you; the SVR simply starts charging from day one, typically adding hundreds a month on an average balance. You’re free to leave the SVR at any time without early-repayment charges, which is why arranging the replacement deal in advance makes the whole event a non-event.
How soon before my fixed rate ends can I remortgage?
You can secure a new deal up to six months before your current fix expires, timed to start the day it ends — so no early-repayment charge applies, because you never actually leave early. This “rate reservation” works both with your own lender (product transfer) and with new lenders, and it’s asymmetric in your favour: if rates rise after locking, you keep your rate; if they fall, most lenders and brokers let you swap to the better deal before completion. Since a full remortgage takes four to eight weeks, six months out is the right time to start, not a moment of overkill.
Do I have to remortgage when my fixed rate ends?
No — nothing obliges you to. If you do nothing you’ll sit on the lender’s SVR indefinitely, with the mortgage otherwise running as normal. The SVR even has legitimate uses: it carries no early-repayment charges, so it’s a sensible short bridge if you’re about to sell, repay a lump sum, or move. As a passive long-term home it’s simply the most expensive option available — on a £200,000 balance, roughly £3,800 a year more than a competitive fix — which is why “doing nothing” deserves to be treated as the active, costed decision it really is.
Should I do a product transfer or a full remortgage?
Compare, then choose — never default. A product transfer (staying with your lender) is fast and frictionless: often done online, no affordability check, no valuation, no solicitor — genuinely the right answer when your lender’s retention pricing is sharp or your circumstances have become harder to underwrite. A full remortgage opens the entire market and takes four to eight weeks; it wins when another lender prices better (common) or when your improved loan-to-value unlocks a cheaper rate tier. The only mistake is comparing your lender’s shelf against nothing — a whole-of-market broker runs both in one pass, usually free.
Can I leave my fixed rate mortgage early?
Yes, but usually at a price: leaving mid-fix triggers the early repayment charge in your deal, typically 1–5% of the balance depending on time remaining. Sometimes paying it is genuinely worth it — the break-even maths against a much cheaper deal is covered in our when-to-remortgage guide — but for most people approaching expiry the smarter route is the free version: apply in advance with the new deal starting the day the fix ends, which achieves the switch with no ERC at all. Once you’re on the SVR, no charges apply and you can leave whenever you like.
What if I can’t afford the new higher payments?
Act early and use the toolkit. Extending your term reduces the monthly payment (FCA rules even allow extending and switching back within six months without a new affordability check); your lender is required to offer support options if you contact them about payment difficulty — and calling before any missed payment keeps your credit record clean and every door open, including hardship measures like temporary arrangements. A broker can also hunt the market for the lowest genuinely available payment shape. The one move with no upside is silence on the SVR: it’s the highest payment of all the options while feeling like avoiding the problem.
