Deposit as % of Property Price

The bigger your deposit (lower your LTV), the better the mortgage rate. Defaults: £30k on £300k = 10%.

Updated May 2026, using HMRC 2026/27 rates and current ONS / gov.uk figures.

UK lenders offer banded rates: 60%, 75%, 85%, 90%, 95% LTV. Crossing into a lower-LTV band typically saves 0.2-0.5% on the rate — significant over a 25-year term.

Worked examples

£15k deposit on £300k = 5% — FTB scheme territory

£30k on £300k = 10% — standard FTB

£75k on £300k = 25% — best mainstream rates

Frequently asked questions

How big a deposit do I need?

5% is the absolute UK minimum (with schemes); 10% standard for FTB; 25% gets the best rates in normal market conditions.

Does a bigger deposit always mean a better deal?

Yes within bands — but going from 75% to 60% is less impactful than 90% to 85%. The biggest jumps in rate happen below 90% LTV.
