What counts as an emergency boiler repair

An emergency boiler repair is required when your boiler fails suddenly and you are left without heat or hot water, or when there is a safety concern such as a suspected gas issue, repeated lockouts, or a significant leak. The priority is always safety first, then restoring heating and hot water as quickly as possible.

If you suspect carbon monoxide (CO) or your CO alarm sounds, leave the property and call 999 before doing anything else.

Key takeaways

  • No heating or no hot water often indicates a lockout, low pressure, ignition fault, or a failed component.
  • Repeated resets usually means the underlying fault is still present and needs professional diagnosis.
  • Leaks can quickly cause damage. If you can do so safely, isolate the boiler and call us.
  • Diagnosis first means you get clear options and costs before work starts.

What we need on the call

Having the details below ready helps us book the right engineer and reduce delays:

Your postcode
Boiler make and model
Fault codeor flashing light pattern
No heating, no hot water, or both
Any visible leakaround the boiler or pipework

Safe checks you can do now

These quick checks are safe for most homes and can help us book the right engineer and parts. If you are unsure, skip these steps and call us.

Check the boiler pressure

Many systems run best around 1.0 to 1.5 bar when cold. If it is very low, your boiler may lock out.

Check the thermostat and timer settings

Replace thermostat batteries if applicable.

Look for an error code or flashing lights

Tell us the exact code or LED pattern.

Try one reset only

If the boiler locks out again straight away, stop resetting and call.

Check for visible leaks

Around the boiler, pipework and pressure relief outlet. If safe, place a towel and avoid electrical contact.

Frozen condensate pipe

In freezing weather this can stop some modern boilers. If you suspect it, tell us and we can advise the safest next step.

How quickly can you attend an emergency boiler breakdown in London?

We aim to attend as soon as possible, subject to engineer availability and your location. Same-day slots are often available. Call 0203 868 6251 and we will confirm the next available option.

My boiler is in lockout. Is it safe to keep resetting it?

Try one reset only. If the boiler locks out again straight away, stop resetting and contact us. Repeated resets can hide an underlying issue and may risk further damage.

What information should I have ready when I call?

Boiler make and model, any fault code or flashing lights, whether you have no heating or no hot water, your postcode, and whether you can see any leaks.

Do you repair all boiler brands?

We repair most major boiler brands. See boiler brands we repair or call us and we will advise based on your boiler.

Do you quote before carrying out repairs?

Yes. After diagnosis, we explain the issue and confirm costs before repairs begin.

Can a power flush fix emergency heating issues?

Sometimes. If sludge or circulation problems are causing poor heating, a power flush can be the right solution. We will advise after diagnosis.

Still stuck?
