Frequently Asked Questions About Boiler Repair
How much does boiler repair cost in the UK?
Most boiler repairs cost £150–£400 including parts and labour. Simple fixes like re-pressurising or replacing a thermocouple are at the lower end. PCB replacement can reach £400–£600.
How long does a boiler service take?
A standard annual boiler service takes 45–90 minutes. The engineer checks combustion, cleans components, and issues a safety record.
What is a Gas Safe engineer?
Gas Safe registered engineers are legally authorised to work on gas appliances in the UK. Always check the Gas Safe Register before letting anyone work on your boiler.
Is same-day boiler repair available?
Yes. GeraHome offers emergency same-day boiler repair. Emergency out-of-hours rates may apply. Book as early as possible for fastest response.
My boiler is making a banging noise — what is it?
Banging or kettling noises usually indicate limescale on the heat exchanger or trapped air. Both are fixable. Book a diagnostic to confirm the cause.
Should I repair or replace my old boiler?
A boiler over 15 years old with recurring faults is often more economical to replace with a modern A-rated unit that saves on energy bills. Your engineer will advise on the cost-benefit.
Can you issue a landlord gas safety certificate?
Yes. All GeraHome gas engineers are qualified to issue CP12 landlord gas safety certificates, required annually for rental properties.
How do I repressurise my boiler?
Locate the filling loop (usually a flexible hose beneath the boiler), open both valves slowly until the pressure gauge reads 1–1.5 bar, then close the valves. If pressure keeps dropping, call an engineer.
