Safety first, before tools
The first part of any emergency gas boiler repair is safety. We’ll ask about gas smells, leaks, strange noises or symptoms that could indicate a carbon monoxide risk. If it’s unsafe, we’ll tell you immediately what to do.

When heating fails, we deal with it calmly
Most emergency boiler calls start the same way: cold radiators, no hot water, or a boiler making a noise it definitely shouldn’t.

How emergency boiler call outs actually work
When heating fails, vague promises aren’t helpful. Here’s what happens when you book an emergency boiler repair in London with us.
Proper fault finding
Many boiler emergencies are actually gas appliance repair service issues — failed valves, sensors, pressure components or circulation problems. We diagnose properly instead of pressing reset and hoping.
Make-safe when needed
If a full fix isn’t sensible on the spot, we carry out proper make-safe work. That means isolating gas, stopping leaks, securing electrics and leaving the property safe until a repair or replacement can be planned.
What counts as a boiler emergency?
Not every fault is dangerous — but some definitely are. We’re called out to leaking boilers dripping into electrics, flues that have failed inspections, and systems that lock out repeatedly because something underneath has finally given up. If you’re stuck in that cycle, this quick guide helps with deciding if a boiler should be replaced instead.
We’ve been doing emergency boiler repairs long enough to recognise patterns. The flat where pressure drops every winter. The terrace where sludge was ignored for years. The cupboard install that was never really set up properly.
Boiler Advice / Symptoms
If you’re not sure whether this is an emergency, start with the symptom that matches what you’re seeing:
- Heating and hot water both gone?
- If the pressure keeps dropping
- Boiler leaking — first steps
- When it clicks but won’t ignite
If any of the above involves a strong gas smell, a suspected CO issue, or water reaching electrics, treat it as urgent and call +44 7727 154 746.

Speak to an emergency boiler engineerEmergency boiler repair questions
Is a leaking boiler an emergency?
If water is reaching electrics or ceilings, yes. Turn the boiler off and call immediately. Even slow leaks should be checked before they escalate. If you need a quick checklist, read: Boiler leaking — first steps.
Do you offer emergency boiler repair near me?
If you’re within our London service area, we often can. Tell us your postcode and what the boiler is doing and we’ll be upfront about response time.
Should I repair or replace?
In most cases, repair is sensible if the boiler is in decent condition and the fault is isolated. Replacement starts to make more sense when the boiler is older, keeps breaking down, or a major component failure is likely to repeat. For a quick reality check, use: repair vs replace guidance and (if time is critical) emergency replacement cost comparison.
Will you always recommend replacing the boiler?
No. Many emergency boiler repairs are sensible and cost-effective. We’ll explain the condition, age and options clearly so you can decide.
What should I do while waiting?
Turn the boiler off if it’s behaving erratically. Catch any leaks safely. Don’t remove covers or attempt repairs yourself. If it’s a total shutdown, this helps: Heating and hot water both gone?
