What we fix (common boiler faults)
A proper boiler repair starts with proving what’s wrong — not guessing. These are the issues we see daily across London flats, terraces and rentals.
Boiler losing pressure
The “keeps dropping” problem — PRV behaviour, expansion vessel issues, hidden leaks, filling loop mistakes.

When people call for “a boiler repair”, it’s usually one of these three patterns. If yours matches, these quick symptom guides will help you understand what it could be, what’s safe to do right now, and when it’s time to stop guessing and get a Gas Safe engineer involved.
- loud banging noises overnight
- boiler keeps shutting down when it’s cold
- burning smell near the boiler cupboard
If anything feels unsafe (strong smell, scorch marks, or you feel unwell), don’t wait — use our emergency boiler repairs hub and we’ll talk you through the next step.
How we handle boiler repairs (proper diagnosis first)
The most common reason boiler repairs fail is simple: the fault was never properly proven in the first place. We focus on fault-finding first — then a repair that makes sense.
We’ll ask for the boiler make/model, any fault code, and what happened before it failed. Then we’ll explain what’s likely going on, what can be checked quickly, and what needs proper testing.
If a repair doesn’t make sense (age, repeated failures, parts viability), we’ll say it and point you toward boiler installation options without the hard sell. If you’re researching replacement costs, this guide helps: new boiler cost & installation in London.
- ✓We fault-find with measurements, not guesses

Before you book a boiler repair
A lot of “boiler repairs” start as a simple fault check — and if it’s an obvious issue, you can save time (and money) by confirming it first. If you’re stuck, we can diagnose properly and get it resolved.
If your boiler has gone completely cold, start with Quick checks before booking a call-out. If you’ve noticed dripping, damp or staining near the unit, read If you’ve found water around the boiler. Unsure if it’s urgent or safe to leave? Is this urgent? Use this guide. And if the boiler fails overnight and you’re planning the next step, this explains After-hours repairs: what to expect.

Boiler repair FAQs
How fast can you get to me for a boiler repair?
We’re open 24/7 (Mon–Sun). Availability depends on the day and where we are in London, but we’ll give a realistic ETA. If you can, tell us the boiler make/model, any fault code, and what happened before it stopped. If it’s failed overnight and you’re planning the next step, read: After-hours repairs: what to expect.
Do you cover my area for boiler repairs?
We mainly cover Newham, Tower Hamlets, Hackney, Waltham Forest, Redbridge and Barking & Dagenham, and we’re based in Forest Gate (E7). We regularly attend E-postcodes plus IG and RM ranges listed above.
My boiler keeps turning off. Should I keep pressing reset?
Reset once only. If it locks out again, don’t keep resetting it — it can make diagnosis harder and sometimes worsens the issue. Use our lockout and error code guide then call with the details.
What should I do right now if I have no heating / no hot water?
Start with Quick checks before booking a call-out (pressure, thermostat/programmer, frozen condensate signs). If it doesn’t recover or you’re unsure it’s safe, call us and we’ll advise.
What if I’ve found water around the boiler?
Don’t ignore it. Some leaks are minor (like discharge/condensate), but others mean you should isolate power and avoid running the boiler. Use If you’ve found water around the boiler to check what to do next. If you’re unsure whether it’s urgent or safe to leave, use Is this urgent? Use this guide.
What does a boiler repair normally cost in London?
Costs vary by fault, parts, access, and timing. We’ll give an estimated price on the phone where possible, then confirm it after diagnosis once the fault is proven. For ranges and cost drivers, see: boiler repair cost in London.
