The remortgage opportunity in 2026
Roughly 1.7 million UK fixed-rate mortgages mature in 2026, including a large cohort who fixed in 2021-2022 at historically low rates. Most of these borrowers face a meaningful rate jump on remortgage. The question is not whether to remortgage but to whom, at what rate, and with what term and product structure.
The single biggest mistake UK borrowers make is letting their fixed deal expire and rolling onto the Standard Variable Rate (SVR). In May 2026, average SVRs sit around 8%; competitive 5-year fixed remortgage rates sit around 4.3-4.8%. On a £200,000 balance over 20 years, that gap is about £400 per month. Multiplied across the millions of mortgages reverting to SVR every year, it's the single largest avoidable cost of UK homeownership.
When to start a remortgage
UK lenders typically issue mortgage offers valid for 3-6 months. That means you can lock in a remortgage offer 3-6 months before your current deal ends. Most brokers recommend starting the process at month 6.
The key timings:
- 6 months out - speak to a broker, get soft searches across lenders, pick a deal and apply.
- 4-5 months out - formal mortgage offer issued.
- 1-2 months out - conveyancing begins.
- Day after current deal ends - new mortgage starts; no ERC paid; no SVR exposure.
If rates fall between your offer and completion, most lenders let you switch to the lower rate at no cost. If rates rise, you keep your locked offer. So locking early is asymmetric upside.
Product transfer or remortgage to a new lender?
Two routes when your fix ends. They're meaningfully different.
Product transfer (staying with your current lender)
- Faster: typically 1-2 weeks.
- No new affordability assessment (most lenders).
- No legal fees.
- No valuation in most cases.
- Limited to your existing lender's rates only.
Remortgage to a new lender
- Slower: typically 4-8 weeks.
- Full affordability and credit assessment.
- Legal fees apply (~£500-£1,000), often paid by the new lender as part of a "free legals" package.
- Valuation usually free.
- Access to whole-of-market rates.
A broker compares both routes for you. Often the new-lender rate beats the product-transfer rate by enough to justify the extra paperwork; sometimes the product transfer wins on speed and convenience. The right answer depends on your numbers.
The remortgage process step by step
- Decide your goals. Just switching for a better rate? Capital raising for home improvements? Debt consolidation? Term reduction? Goal drives the lender choice.
- Speak to a broker (or whole-of-market search). Soft searches across lenders to see your real options.
- Pick a deal. Fix length, rate, fees, ERCs, overpayment allowance.
- Full application. ID, 3 months bank statements, payslips (employed) or accounts (self-employed), credit check.
- Valuation. Lender's valuer assesses the property (usually free, sometimes a desktop valuation).
- Mortgage offer. Issued within 1-3 weeks of full application for clean cases.
- Conveyancing. The new lender's solicitor handles the legal work to discharge the old mortgage and register the new charge.
- Completion. New mortgage starts; old mortgage paid off. New monthly payment kicks in.
Capital-raising remortgage
A capital-raising remortgage uses equity built up in your property to borrow additional funds. Common reasons:
- Home improvements - extensions, loft conversions, kitchens, energy efficiency.
- Debt consolidation - paying off higher-interest unsecured debt (credit cards, personal loans). Move debt from 20%+ to 4-5%. But you're securing previously unsecured debt against your home, and you may pay more interest over a longer term. Take advice.
- School fees / education - private school, tuition.
- Business investment - lump sum to fund a business (lender may treat this as a buy-to-let style criteria).
- Buy-to-let deposit - releasing equity to fund a deposit on a separate investment property.
- Gifting to family - gifted deposits to children for their first home.
Lenders treat capital raising similarly to a fresh application: full affordability assessment, possible additional documentation (e.g. contractor quotes for home improvements). The interest rate is the same as your main mortgage - which is almost always cheaper than personal loans or credit cards.
Early Repayment Charges (ERCs)
ERCs apply if you redeem your mortgage during the fixed or discount period. Typical structures:
- 5/4/3/2/1 - 5% of balance in year 1, falling 1% per year over a 5-year fix.
- 5/3/1 - 5% year 1, 3% year 2, 1% year 3 for a 3-year fix.
- 2/1 - 2% year 1, 1% year 2 for a 2-year fix.
Use the Early Repayment Charge calculator to model the cost of breaking your current deal.
Most remortgage applications time completion to match the day your current fix ends, avoiding ERCs entirely. The rare cases where breaking early makes sense: rate movements so favourable that the saving exceeds the ERC over the remaining fix period.
Fixed, tracker, or discount?
Fixed-rate (most popular)
Rate locked for 2, 3, 5, or 10 years. Payment certainty. ERCs apply during the fixed period. Best for borrowers who value predictability or who think rates may rise. 5-year fixes dominate the 2026 market.
Tracker
Rate tied to the Bank of England base rate plus a margin. Moves with BoE decisions. Often no ERCs (lifetime tracker) or short ERC periods. Best for borrowers who expect rates to fall or who want flexibility.
Discount
Rate tied to the lender's SVR minus a discount. Moves with lender decisions, not BoE directly. Less predictable than tracker; not commonly recommended in 2026.
The total cost of remortgaging
- Product fee - £0 to £1,999, often addable to the loan. Fee-free products usually have slightly higher rates.
- Valuation - free for most remortgages.
- Legal / conveyancing fees - £500-£1,000, often covered by "free legals" from the new lender on standard remortgages.
- Broker fee (if any) - £0 to £500. Many brokers charge no fee for remortgages, being paid via lender procuration fee instead.
- ERC from current deal - only if breaking early. Plan to time completion to your fix end date.
For most remortgages, the all-in cost is £0-£500. The monthly saving from a competitive rate vs SVR usually pays back the cost in a single month.
Who specifically benefits from remortgaging?
| Situation | Likely best move |
|---|---|
| Fix ending in next 6 months | Start remortgage now to lock today's rate |
| Already on SVR | Remortgage immediately - this is costing you ~£400/month |
| Significant equity built up | Remortgage to a lower LTV band for better rates |
| Want to release £20k+ for renovations | Capital-raising remortgage |
| High-interest unsecured debt | Debt consolidation remortgage (take advice first - converting unsecured to secured is serious) |
| Income or credit improved since taking out current mortgage | Likely qualify for better rates now |
| Income dropped or credit hurt since last application | Product transfer is the safer route (no new affordability check) |
| Approaching age 70+ | Specialist later-life lender or RIO product needed |
Why use a broker for remortgaging?
Product transfers from your existing lender are easy to do yourself - log in, click the new deal, sign. The catch: you have no idea if it's a competitive rate. UK lenders routinely offer product-transfer rates 0.3-0.5% above what they'll offer a new customer with the same profile.
A whole-of-market broker compares your existing lender's product transfer rate against new-lender rates from across the market and tells you the cheapest after all costs. They also understand which lenders accept which forms of income (self-employed, contractor, retired), which can be the difference between a yes and a no on a non-standard case.

Frequently asked questions
When should I start a remortgage?
Six months before your current fixed-rate deal ends. UK lenders typically let you secure a new mortgage offer up to 6 months in advance, which means you can lock in today's rate even if completion is months away. If rates fall before completion, you can usually switch to a better deal at no cost. If rates rise, you're protected.
How long does a remortgage take in 2026?
Typically 4 to 8 weeks from full application to completion, assuming a straightforward case. The most common delays are property valuations on non-mainstream properties and conveyancing on leasehold flats (where the management company has to be contacted). A product transfer with your existing lender is faster - often completed in 1-2 weeks - but limits you to that lender's deals.
Will I have to pay early repayment charges?
Only if you switch before your current fixed-rate or discount period ends. Most UK fixed-rate mortgages have ERCs ranging from 1% to 5% of the outstanding balance, often tapering down each year. Use our Early Repayment Charge calculator to estimate the cost. In some cases the savings from switching outweigh the ERC; for most borrowers, timing the remortgage for the month your current deal ends avoids ERCs entirely.
Can I borrow more when I remortgage?
Yes. A capital-raising remortgage lets you borrow against equity that has built up in your property - for home improvements, debt consolidation, school fees, business investment, or other purposes. The lender will reassess affordability and the property value. Capital raised against a residential mortgage is typically charged at the same rate as your main mortgage, which is usually much lower than personal loans or credit cards.
What happens if I don't remortgage at the end of my fix?
Your mortgage reverts to the lender's Standard Variable Rate (SVR), which is almost always significantly higher than the fixed rate you came off. UK SVRs in 2026 typically sit between 7% and 9%. On a £200,000 mortgage, the difference between an SVR of 8% and a remortgaged 4.5% fixed rate is roughly £400 per month - £4,800 per year. Not remortgaging is one of the most expensive financial decisions you can make.
Product transfer or remortgage to a new lender?
A product transfer (staying with your current lender on a new deal) is faster, has no legal fees, and avoids a new affordability assessment. A full remortgage to a new lender gives you access to potentially better rates but requires a full application, valuation, and legal work. A broker can compare your existing lender's product transfer rates against the whole market and recommend whichever is genuinely cheapest after all fees.
Will remortgaging hurt my credit score?
A formal application triggers a hard credit search, which leaves a footprint on your file for 12 months. The footprint itself has a minor short-term impact on your credit score; lenders are not concerned by occasional hard searches. A broker can run soft searches across multiple lenders before any hard search is needed, protecting your file while comparing deals.
