Boiler replacement cost depends on the boiler type, required output, property size and the amount of installation work involved. A straightforward same-location replacement will usually cost less than a boiler conversion or relocation. Get a property-specific quote before comparing prices.
The main factors are the boiler model, boiler size, whether it stays in the same location, changes to pipework or controls, system upgrades and whether the existing heating system needs additional work.
Usually, yes. Keeping the new boiler in the same position can reduce the amount of pipework and installation work required. Moving the boiler may increase the overall replacement cost depending on the property.
A Let’s Heat quotation will explain what is included for your property, including the boiler, installation work and any agreed additional components or system changes. Always check the quotation rather than assuming every installation includes the same items.
Finance options may be available to help spread the cost of a new boiler, subject to status, eligibility, lender approval and availability.
Annual servicing is recommended and may be required under the manufacturer's warranty conditions. A service allows the boiler's safety, condition and operation to be checked and can help identify developing problems early.
