What affects the payment

Three levers change the monthly cost of a £150,000 mortgage the most:

Interest rate — the biggest variable in the short term. A 0.5% difference on £150,000 over 25 years typically costs tens of thousands in total interest.
Term length — a shorter term (e.g. 20 years) means higher monthly payments but far lower total interest. A 30-year term lowers monthly cost but greatly raises what you pay overall.
Deposit / LTV — bigger deposits unlock lower rates. Crossing thresholds at 90%, 85%, 80% and 60% LTV each moves you into a better rate band.

How to reduce what you pay overall

If you can afford it, a shorter term saves the most interest. If flexibility matters more, most UK mortgages let you overpay up to 10% per year during a fixed term without penalty — even modest overpayments dramatically cut the total interest on a loan this size. Remortgaging to a lower rate at the end of each fixed period is the other major saving.

Costs not included in the payment

The monthly figures above cover principal and interest only. On top of that you'll also budget for buildings insurance, possibly Stamp Duty (depending on the property price), lender arrangement fees, and — if buying — the deposit itself, conveyancing, and survey costs.

Frequently asked questions

What income do I need for a £150,000 mortgage?

As a rough guide, UK lenders typically lend 4 to 4.5 times your annual income. So a £150,000 mortgage suggests a household income of roughly £30 to £30 — subject to affordability checks and your other financial commitments.

Is a £150,000 mortgage over 25 or 30 years better?

25 years is the traditional UK default and costs less in total interest. 30 years lowers the monthly payment but raises the total cost. Pick the shortest term whose monthly payment fits comfortably.

How does the rate change my monthly cost?

On £150,000 over 25 years, each 0.5% change in rate typically shifts your monthly payment by £43 or so, and thousands over the full term.

Can I get a £150,000 mortgage as a first-time buyer?

Yes — many first-time buyer products lend £150,000 and above at 90% or 95% LTV, though rates are higher than at lower LTVs. Government schemes like shared ownership may also apply depending on the property.
