Boiler Repairs & Parts FAQs
From faulty parts to full boiler repairs — our Gas Safe engineers explain what can go wrong, what’s repairable, and when it’s time to replace your system.
What are the most common boiler faults?
Common issues include low pressure, ignition failure, leaking pipes, and worn-out valves or sensors. Our engineers can diagnose these quickly on-site.
Can all boiler parts be replaced?
Most parts can be replaced, including fans, pumps, sensors, and diverter valves. However, if your boiler is very old or discontinued, replacement may be more cost-effective.
Do you carry parts on your vans?
Yes — we keep the most common parts in stock to fix 8 out of 10 breakdowns on the first visit.
Are your repairs guaranteed?
Yes. All Blue Flame repairs come with a 12-month parts and labour guarantee for peace of mind.
When is it better to replace than repair?
If repairs are frequent or parts obsolete, a new boiler can save money long-term. Our engineers provide honest advice before any major repair.
