What Happens When Your 2-Year Fixed Mortgage Ends? Refix Risk Explained
A 2-year fixed mortgage does exactly what it says: it fixes your rate for 24 months. What it does not do is fix what happens next. At the end of those two years, your lender automatically moves you onto their Standard Variable Rate (SVR) unless you act. That transition — and the risk it carries — is called refix risk. It is one of the most important factors in the 2-year vs 5-year fixed mortgage decision, and it is largely invisible until it lands.
What is refix risk?
Refix risk is the uncertainty you take on every time your fixed rate ends and you must negotiate a new deal. With a 2-year fix, you face this moment every 24 months. With a 5-year fix, you face it every 60 months.
The risk has two components:
Rate risk: The market rate at your refix date may be higher than the rate you locked in. You cannot know today what rates will be in two years. If they have risen, your new deal will be more expensive than your current one.
SVR exposure: If you do nothing when your fix ends, your lender moves you automatically onto their SVR. SVRs are not linked to the best available market rates — they are set at the lender's discretion and can change at any time. The SVR is almost always materially higher than the best available fix. The current figures are in the table below.
The £ cost of doing nothing
The SVR penalty is not abstract. Here is what it costs in real money if your 2yr fix ends and you roll onto SVR instead of refixing:
| New 2yr fix at 5.89% | SVR at 7.27% | |
|---|---|---|
| Monthly payment (£200k, 25yr term) | £1,275 | £1,449 |
| Monthly SVR penalty | £174/month | |
| Annual SVR penalty | £2,088/year | |
| Rate certainty | Fixed for 24 months | Can change at any time |
Illustrative. Based on £200,000 repayment mortgage, 25-year term. SVR average from Moneyfacts, April 2026. Actual payments depend on lender, balance, and remaining term.
The monthly and annual SVR penalty is in the table above. This is the refix risk cost when you do nothing. It is avoidable with early action.
Your three options at refix
| Option | What it means | Speed | Best for |
|---|---|---|---|
| Product transfer | New deal with your current lender — no affordability checks, no legal work | Fast (days) | Speed, simplicity, unchanged circumstances |
| Remortgage to new lender | Full application — affordability checks, valuation, legal transfer | 4–8 weeks | Best market rate, changed circumstances, borrowing more |
| Stay on SVR | Do nothing — automatic rollover at lender's rate | Instant | Short-term flexibility only (balance under £50k, moving imminently) |
Product transfer and remortgage are both forms of refixing. SVR is the default if neither is arranged in time.
Product transfer is the fastest route and requires no legal work. The trade-off: you are limited to your current lender's product range, which may not be the most competitive. A full remortgage opens the whole market but takes several weeks — which is why timing matters.
The refix timing window
Most UK lenders allow you to lock in a new rate well before your current fix ends. The locked rate is guaranteed even if rates rise before your fix expires. If rates fall in the interim, many lenders allow you to switch to a lower rate before completion at no cost.
| Time before fix ends | Action | Why |
|---|---|---|
| 6 months | Start comparing product transfer vs whole-market remortgage | Maximum choice, no pressure |
| 3–4 months | Lock in your new rate | Protected if rates rise before expiry |
| 1–2 months | Confirm paperwork, chase completion | Avoid SVR gap on switchover date |
| 0 months (expired) | You are on SVR — act immediately | Every month costs £174+ more than a new fix |
Why refix risk is asymmetric for 2yr vs 5yr borrowers
A 2yr fix creates this refix moment every 24 months. A 5yr fix creates it every 60 months. Over a 10-year horizon, a borrower on consecutive 2yr fixes faces this risk significantly more often than one on 5yr fixes — the exact comparison is in the table below.
Each refix is an exposure to the market rate at that moment. If rates have risen by the time you refix, your payments go up. If rates have fallen, you benefit. The 2yr fix gives you more frequent opportunities to capture rate falls — but also more frequent exposure to rate rises and the friction costs of refixing (product fees, broker fees, legal costs on a full remortgage).
The 5yr fix reduces that friction and eliminates the majority of those refix events, at the cost of locking in for longer.
Worked example: refix cost over 10 years
Assumptions: £200,000 repayment mortgage · 25-year term · current rates (Moneyfacts, April 2026)
| 2yr fix strategy | 5yr fix strategy | |
|---|---|---|
| Starting rate | 5.89% | 5.77% |
| Refix events over 10 years | 5 | 2 |
| SVR exposure risk | 5 transition points | 2 transition points |
| Product/broker fee events | Up to 5 × ~£500–£1,000 | Up to 2 × ~£500–£1,000 |
| Estimated 10yr friction costs | £2,500–£5,000 | £1,000–£2,000 |
Illustrative. Product fee estimates based on typical UK market. Actual fees vary by lender and deal.
Whether the rate flexibility of the 2yr fix justifies those additional friction costs depends on how rates actually move — which neither you nor any lender can predict with confidence.
What to do next
Refix risk is one input into the 2yr vs 5yr decision — not the whole answer. It interacts with the current rate gap, your ERC position, and your personal plans. For the complete decision framework, see our 2-year vs 5-year fixed mortgage guide.
