Frequently Asked Questions

Find answers to common boiler, heating, and hot water problems. If you need urgent help, our engineers are ready to assist.

Why has my heating and hot water stopped working?

There are several reasons why your heating and hot water may stop working. Common causes include low boiler pressure, frozen condensate pipes, a faulty thermostat, pilot light issues, or internal boiler faults. If basic checks don’t restore service, it’s best to contact a Gas Safe engineer.

Why is my boiler making strange noises?

Unusual boiler noises are often caused by air trapped in the system, limescale or sediment buildup, poor water circulation, or worn components. Expansion and contraction of internal parts can also create sounds. Regular servicing helps prevent these issues and ensures safe operation.

Why have I suddenly got no hot water?

Sudden loss of hot water can be caused by power or gas supply issues, thermostat faults, extinguished pilot lights, faulty heating elements, leaks, or extreme cold weather. If basic troubleshooting doesn’t fix the issue, a qualified Gas Safe engineer should inspect the system.

How much will it cost to replace my boiler?

The average cost of boiler replacement typically ranges between £1,500 and £4,000. Prices depend on the boiler type (combi, system, or regular), brand, installation complexity, energy efficiency rating, and location. Higher-efficiency boilers may cost more initially but can reduce energy bills long term.
