Boiler Repair or 
Boiler Replacement?

Boiler repair is a cost-effective option for minor issues that don’t impact the unit’s overall performance. However, if your boiler is over 10-15 years old, frequently breaking down, or significantly inefficient, investing in a new boiler replacement may be more economical and energy-efficient in the long run.

Heating Controls & System Repair

When we have no hot water or no heating and the home is not heated via a combi boiler, we often mistakenly blame the boiler when sometimes the problem is what is controlling the boiler or the heating system’s pipework, radiators or underfloor heating. Correctly identifying the problem within the home is key to a quick resolution.

The Boiler Repair FAQ

We will add quick answers to your questions here and write longer blog articles for the best questions that need detailed answers!

Yes certainly. Unless the emergency is a weekend when the mighty Newcastle are playing.

Most models can be repaired; however, parts for budget boilers are very expensive and may be deemed best to replace.

The average cost can range from £150+VAT to £400+VAT, depending on the issue and the time required and need for replacement parts.

The process involves opening the filling loop valves; however, if you’re unfamiliar, consult a technician.

Typically, parts are an additional cost to boiler repairs unless the repair is completed without parts. ie loose wiring, blocked condensates.

Repair times vary but simple issues may be fixed within an hour, whereas complex problems could take longer hence why most repair companies may charge by the hour to diagnose & repair faults.

If the boiler is over 15 years old and frequently breaking down, it’s often more cost-effective to replace it.
