Best Boiler Replacement Guide 2026: Costs, Grants & Top Brands

Quick Summary: A new A-rated condensing boiler costs £1,795-£3,500 installed. Replacing a 15+ year old boiler can save £300-500/year on energy bills and improve your EPC rating by 1-2 bands. Fixed-price installations are now available with next-day fitting.

Should You Replace Your Boiler in 2026?

If your boiler is over 10-15 years old, it's probably costing you hundreds more than necessary each year. Modern condensing boilers are 90-95% efficient, compared to 60-75% for older models. That's a significant difference in your energy bills.

Use our free property search to check your home's current EPC rating and see how an efficient boiler could improve it.

E-rated to A-rated: Save £200-350/year

A new efficient boiler can improve your EPC rating by 8-15 points - often enough to jump one or two bands:

E to D: Opens rental property to more tenants
D to C: Meets proposed 2026 landlord requirements
C to B: Premium property status, higher value

Search your property to see your current heating system efficiency and how much you could improve.
