A capped mortgage is a type of variable-rate mortgage that includes a maximum interest rate ceiling. Your monthly payments can fall when market rates drop, but they will never exceed the agreed cap — giving you a blend of variable-rate flexibility and fixed-rate security.
How Does a Capped Mortgage Work?
A capped mortgage tracks a variable rate (usually the lender's SVR) but has a maximum rate ceiling. Unlike a fixed-rate mortgage, your payments can go down. Unlike a standard tracker, there's a safety net if rates spike.
- Starting rate: 4.5% (SVR)
- Cap: 6.0%
- If SVR rises to 7%: you pay 6.0% (protected by cap)
- If SVR falls to 3.5%: you pay 3.5% (benefit from the drop)
See our guide on what counts as a good rate in 2026 to understand how capped rates compare to the wider market.
Pros and Cons
- Pro: Protection against large rate increases — peace of mind like a fixed rate
- Pro: You benefit when rates fall — unlike fixed deals
- Pro: Often allows overpayments without penalty
- Con: Cap is usually higher than equivalent fixed rates
- Con: Very few products available in 2026
- Con: May have early repayment charges — check the fees
Alternatives to Consider
Since capped mortgages are rare, consider these alternatives:
- Fixed-rate mortgages — guaranteed payments for 2–10 years
- Tracker mortgages — follow the base rate with no cap, but with flexibility
- Discount mortgages — a set discount off the SVR
- Offset mortgages — use savings to reduce interest
