What Is Gas Boiler Repair?

A gas boiler is the heart of your central heating system. It heats water by burning natural gas, then circulates that hot water through pipes to your radiators, baseboards, or underfloor heating — keeping your home warm, comfortable, and safe.

Over time, parts of the boiler can wear out, become blocked, or lose efficiency. Gas boiler repair involves diagnosing and fixing these issues to restore proper function. This may include repairing or replacing faulty components, cleaning blocked passages, and ensuring the system is running efficiently.
