What is a capped rate mortgage?

Full answer

Capped rate mortgages are a relatively uncommon but useful hybrid between fixed and variable rate mortgages, offering a middle ground between the two more common options. **How a capped rate works** Your interest rate moves in line with a variable rate (often the lender's standard variable rate or the Bank of England base rate plus a margin), so your monthly payments can go up or down over the deal period -- but the lender guarantees the rate will never exceed a specified maximum ("cap") during the agreed term, giving you certainty about the worst-case scenario even while retaining some flexibility. **Comparison with fixed rate mortgages** A fixed rate mortgage locks your interest rate completely for the deal period, so your payments never change regardless of what happens to market rates -- with a capped rate mortgage, your payments can still fall if the underlying variable rate drops, which a fixed rate mortgage does not allow, but they can also rise (just not above the cap). **Comparison with standard tracker or variable mortgages** A standard tracker mortgage moves directly with the base rate (or another reference rate) with no upper limit, meaning your payments could rise significantly if rates increase sharply. A capped rate mortgage offers the same potential for lower payments if rates fall, but with the reassurance of a guaranteed ceiling on how high your rate can go. **Why capped rate mortgages are less common** Lenders offer capped rate deals less frequently than straightforward fixed or tracker products, partly because pricing the cap accurately (the maximum rate the lender is willing to guarantee) can be complex, and partly because demand has historically been lower than for simpler fixed or tracker products -- availability varies significantly depending on market conditions, so you may need to search more widely or use a mortgage broker to find a suitable capped rate deal. **Who might consider a capped rate mortgage** Borrowers who want some protection against rising rates, but who also want the possibility of benefiting if rates fall (which a fixed rate does not offer), may find a capped rate deal appealing -- though it is worth comparing the cap level and the deal's overall cost carefully against both fixed and tracker alternatives, since capped deals are sometimes priced at a premium reflecting the guarantee. **Worked example** A capped rate mortgage tracks the base rate plus 1%, capped at a maximum of 6% for five years. If the base rate rises such that the tracked rate would exceed 6%, the borrower still only pays 6% -- if the base rate falls, their rate falls with it, below the cap. **Practical tip** Use the Mortgage calculator to compare your likely monthly payments under a capped rate deal's cap level against equivalent fixed and tracker products, so you understand the true worst-case and best-case scenarios for each option.
