Monthly Payment Breakdown for a £150,000 Remortgage
The following monthly repayment figures are based on a £150,000 repayment mortgage with a 25-year remaining term, reflecting current UK market rates in 2025.
At a 5-year fixed rate of 4.3%, the monthly repayment is approximately £817. At a 2-year fixed rate of 4.6%, the monthly cost is around £842. On a standard variable rate of 7.5%, the monthly payment is approximately £1,108.
The monthly saving from moving off the SVR onto the 5-year fix is around £292 — an annual saving of approximately £3,500 and a total saving of roughly £17,500 over five years. The 2-year fix versus SVR comparison saves about £266 per month, or approximately £3,194 per year.
It is worth noting that these figures assume a remaining term of 25 years. If your remaining term is shorter — say 15 or 20 years — your monthly payments will be higher but your total interest paid will be lower. For example, £150,000 at 4.3% over 20 years costs around £927 per month versus £817 over 25 years. The £110 monthly difference is worth considering if you can afford the higher payment, as you will clear your mortgage five years sooner and save a significant amount in interest.
LTV Ratios and Rate Tiers for a £150,000 Loan
At £150,000, your LTV will depend on your property's current value. Lenders segment their rates into bands — 60%, 75%, 80%, 85%, and sometimes 90% LTV — with progressively better rates available as your LTV falls.
A £150,000 loan on a property worth £187,500 equates to exactly 80% LTV. On a property worth £200,000 your LTV would be 75%, and on a property worth £250,000 or more you would be below 60% LTV and eligible for the most competitive products. In many parts of the UK, particularly outside London and the South East, a property purchased in the last decade at £150,000 to £200,000 may well have appreciated enough to place you at or below 60% LTV today.
Crossing from the 75% LTV tier to the 60% tier often unlocks a rate reduction of 0.2 to 0.4 percentage points with many lenders. On £150,000 over 25 years, a 0.3% rate improvement is worth roughly £27 per month — or around £1,620 over five years. Always obtain a current market valuation before applying to ensure you are accessing the best possible rate tier.
For borrowers at 80% to 85% LTV on a £150,000 mortgage, the rate premium versus 75% LTV is typically 0.1 to 0.3 percentage points. This is manageable, and most mainstream lenders are happy to lend at this level. Above 85% LTV, the product range narrows somewhat, but specialist lenders and some building societies still offer competitive options.
