+44 7727 154746 and tell us what the boiler is doing (plus the make/model if you can see it).

Use this emergency checklist and, if needed,
go straight to emergency boiler help.
Typical boiler repair cost ranges (London)
London pricing has its own reality. Parking, congestion, access, parts availability, and out-of-hours demand
all nudge the number up or down. The ranges below are “normal” for a proper visit where the fault is found and fixed safely.
Type of job
Typical range (London)
What usually moves the price
Diagnostic / fault-finding visit You want the root cause identified before parts are thrown at it.
£90–£160
Often deducted/absorbed if you proceed with the repair on the day.
Access to boiler, time on site, and whether you’re in a tight parking / permit zone.
Minor repair (no major parts) Adjustments, small seals, simple control issues, basic system corrections.
£120–£240
How quickly the fault presents itself and whether anything needs draining/refilling.
Common parts replacement Fan, pump, pressure-related components, sensors, diverter-related parts (varies by model).
£220–£520
Part cost, boiler brand, and whether the part is stocked locally or needs ordering.
Out-of-hours / same-day urgency Evenings, weekends, bank holidays.
+£60–£180
Time of day, travel time, and whether parts sourcing is still possible that evening.
Complex repair / multiple issues Older boilers, poor access, repeat faults, or where previous “quick fixes” caused knock-on problems.
£380–£850
Time, diagnostics, parts, and whether additional work is needed to make it safe/reliable.
Real talk: we sometimes arrive and the “repair” isn’t the expensive bit — it’s the access.
Basement flats off King’s Road, tight cupboards in new-builds near Stratford, or a boiler wedged behind a washing machine…
London loves a tricky setup.
Why boiler repair prices swing so much in London
Two people can both say “my boiler’s broken” and the jobs can be completely different.
These are the biggest price movers we see day-to-day:
Parts cost Some components are genuinely pricey, and some brands have higher parts pricing across the board.
If a part is rare and needs ordering, you’re paying for time and logistics, not just the metal/plastic.
Access If we can get to it, test it, and work safely, it’s a straight job.
If it’s boxed in, above a toilet, in a ceiling void, or the cupboard is basically a shoebox… the clock runs.
Out-of-hours Evening/weekend callouts cost more. Not because we love it —
because it’s usually urgent, traffic is unpredictable, parts availability is tighter, and it interrupts other booked work.
Repeat faults The most expensive repairs are the ones where the underlying issue wasn’t fixed first time.
You end up paying twice. That’s why proper diagnostics matters, even when you just want heat back quickly.
London-specific detail: congestion/ULEZ isn’t usually the “headline cost”, but it does affect scheduling and routing.
If you’re in a permit-heavy zone (Chelsea is famous for it), tell us up front — it stops delays and surprises.
Repair vs replace: when a repair stops being the smart move
This is where people want honesty. A repair can be the right call — even on an older boiler — if it’s a single failure and the rest is healthy.
But sometimes the numbers don’t add up.
We start thinking “replacement might be better” when:
multiple major parts have failed in a short time,
parts are hard to source or backordered,
the boiler is inefficient and you’re spending money to keep a poor performer alive,
reliability matters (rental properties, family homes, vulnerable occupants).
Want a straight price range for your boiler repair?
Tell us the boiler make/model and what it’s doing. We’ll give you a realistic range — and if it sounds like an emergency,
we’ll say that too. For London “boiler repair near me” searches, this is the quickest way to cut through the noise.
Scenario CTA: If you’re stuck near the King’s Road / Chelsea area and the boiler’s packed in, mention access and parking when you call —
it helps us plan properly and keeps the quote accurate.
Boiler repair cost FAQs (London)
What’s the average boiler repair cost in London?
Most routine repairs land somewhere between a couple of hundred and a few hundred pounds once parts and labour are included.
The biggest swing is the part cost and whether it’s out-of-hours. If you want a quick range for your exact boiler, call
+44 7727 154746.
Do you charge a call-out fee?
We charge for time and diagnostics because that’s the work that stops repeat faults.
In many cases, if the repair goes ahead on the day, the diagnostic portion is absorbed into the overall job.
If you want it in writing first, use the
contact page.
Why do some companies quote £60 and others quote £250?
Often the “cheap” number is just a foot-in-the-door visit with no meaningful testing included,
or it excludes parts and adds extras once they’re inside your home.
A proper quote explains what’s included, what’s not, and what happens if parts are needed.
Is emergency boiler repair always more expensive?
Usually, yes — because it’s out-of-hours and urgent. If it’s unsafe (gas smell, CO alarm, soot marks),
don’t price-shop first. Use
the emergency checklist
then go to
emergency boiler help.
When does it make more sense to replace the boiler?
When you’re stacking repeated major repairs, parts are hard to source, or reliability is becoming a monthly headache.
If you want to compare options, see
boiler installation.
Can you give a price without seeing it?
We can usually give a sensible range if you tell us the model and what’s happening, but an exact figure comes after diagnosis.
The quickest way to get an accurate range is a photo of the boiler front + any fault code, plus your postcode.
