Service Overview

What it is.
Who it's for.
Why it matters.

What it is

Boiler repair covers fault diagnosis and physical repair on any domestic gas boiler, combi, system or regular. We arrive with the most common spares in the van, diagnose the cause (not just the symptom), and quote a fixed price before we lift a spanner.

Who it's for

Homeowners and landlords with a boiler that's locked out, lost pressure, leaking, banging, displaying a fault code, or producing heat but no hot water (or the other way around).

When you need it

Today, ideally. A boiler making strange noises or losing pressure repeatedly is usually 48–72 hours from a full breakdown. Catch it on the warning sign and the bill is a fraction of an emergency call-out.

Why professional matters

DIY repairs on gas appliances are illegal under the Gas Safety (Installation and Use) Regulations 1998, and dangerous. A bad repair voids your warranty, your insurance, and potentially your safety. A Gas Safe registered engineer is the only legal option.

What Happens If You Leave It

The cost of doing nothing
is always higher than acting.

Cold house in winter

A failed boiler in a UK winter isn't an inconvenience, for elderly or young occupants it's a health emergency within 24 hours.

Water damage from leaks

A pinhole leak in the heat exchanger or PRV will quietly soak floorboards and ceilings for weeks before anyone notices the bill.

Repeat lockouts compound damage

Resetting a boiler that keeps locking out doesn't fix it, it stresses components and turns a £90 repair into a £400 one.

Voided warranty from DIY attempts

One YouTube fix and your manufacturer cover is gone. We can still repair it, but the bill is yours now.

Safety-first diagnosis

The Detail

What we'd tell a friend before they booked.

Most boiler 'faults' fall into a small number of repeatable categories. Twenty years of repair work across East London and Essex has shown us which parts fail in which boilers, in which order, and roughly when. That's why our diagnosis is fast and our quotes are honest.

Common faults and what they actually mean

Low pressure (typically below 1 bar) is usually a leak, expansion vessel failure or a stuck pressure relief valve, not just 'topping up'. F22, F1, EA or 'press reset' codes vary by manufacturer but generally indicate ignition, flame loss or PCB issues.

No hot water but heating still works almost always points at a failed diverter valve. Banging or kettling noises are limescale on the heat exchanger or a sticking pump.

Cold radiators downstairs and hot upstairs (or vice versa) is a circulation problem, often the pump or a sludged-up system. We diagnose properly, we don't just throw parts at the symptom.

Brands we repair

Worcester Bosch, Vaillant, Ideal, Baxi, Viessmann, Glow-worm, Potterton, Alpha, Main, ATAG, Vokera, Ferroli and most others. We're trained on the full Worcester and Vaillant ranges (the two most common in our service area) and carry their common spares in the van as standard.

Older boilers, if parts are still available, we'll repair them; if not, we'll give you honest replacement advice with no pressure.

When repair stops being economical

There's a point at which repair becomes a bad investment, typically when the boiler is over 12–15 years old, the heat exchanger is failing, and the repair quote exceeds 40–50% of replacement cost. We tell you straight.

If a new boiler is the right answer, we'll quote that too (with up to a 10-year manufacturer warranty on the new boiler), but the choice is yours and there's never a pushy upsell. Plenty of 10-year-old boilers are worth keeping alive for another five.

Emergency vs same-day vs scheduled repair

Emergency call-out (24/7) is for genuine emergencies: gas leaks, no heat in winter for vulnerable occupants, water leaks doing active damage. Same-day repair (during working hours) covers most no-heat or no-hot-water faults.

Scheduled repair is for intermittent faults, minor leaks or planned work, typically within 48–72 hours and at a lower call-out rate. We'll talk through which makes sense when you call.

How much does a boiler repair cost?+

Call-outs are priced from £90 + VAT during working hours and from £130 + VAT out of hours. For leaks we'll always make safe within the call-out price. For breakdowns where parts are needed, we'll provide a written quote on the spot and the call-out is still charged.

Can you repair my boiler today?+

Depending on how busy we are, we'll usually get to you the next day and offer same-day attendance whenever we can. Give us a call and we'll be straight with you on the soonest realistic slot.

Do you repair boilers in East London and Essex specifically?+

Yes, Waltham Abbey, Chingford, Loughton, Cheshunt, Enfield, Harlow, Epping and surrounding postcodes are our home patch.

What brands do you repair?+

Worcester Bosch, Vaillant, Ideal, Baxi, Viessmann, Glow-worm, Potterton, Alpha, Main, ATAG and most others. If parts are still made, we can fix it.

What if you can't fix it on the first visit?+

If a non-stock part is needed we'll order on the day and return as soon as it lands, typically 24–48 hours. You only pay the diagnostic until the repair is complete.

Is the repair guaranteed?+

Yes. We give a 12-month guarantee on our workmanship, and any parts we fit carry their full manufacturer guarantee on top.

Do you offer 24/7 emergency repair?+

Yes. Out-of-hours call-out is available 24/7 for genuine emergencies across our service area.

Should I just replace the boiler instead of repairing it?+

Depends on age, repair cost and efficiency. As a rule of thumb, repair makes sense under 12 years old or under 40% of replacement cost. We'll give you both quotes and an honest recommendation.
