Boiler Faults We Repair
From the most common breakdowns to obscure fault codes, our engineers diagnose and repair the full range of domestic gas boiler issues across West Yorkshire.
No heating or no hot water
One of the most common reasons customers call us. Causes range from pressure loss and ignition faults to diverter valve, thermostat or pump problems.
Low boiler pressure
Pressure dropping below 1 bar often points to a leak in the system, a failed expansion vessel or a recently bled radiator. We'll find the cause, not just top it up.
Leaking boiler
A leaking boiler should never be ignored. Common causes include corroded pipework, failed seals, a faulty heat exchanger or pressure relief valve.
Boiler not firing up
If your boiler won't ignite, the cause is often a faulty fan, ignition lead, gas valve, PCB or flue sensor. We test each component before recommending repair.
Noisy boiler or kettling
Banging, whistling or kettling usually means limescale build-up in the heat exchanger or trapped air in the system. Power flush or component repair may be needed.
Thermostat and radiator faults
Cold radiators, uneven heating, or thermostats not responding can stem from sludge build-up, faulty TRVs, airlocks or controller issues — all of which we diagnose and fix.
Pilot light keeps going out
A pilot light that won't stay lit usually points to a faulty thermocouple, blocked jet or draught issue. Common on older boilers in our service area.
Boiler fault codes
From Worcester EA/227, Vaillant F22/F75 and Ideal L2/F1 to Baxi E133 — we know the major brands inside out and bring the right parts to most common call-outs.
Boiler keeps switching off
Intermittent lockouts often come down to flow rate, pressure sensors, condensate pipe freezing, or PCB faults. We diagnose the root cause before suggesting a fix.
Emergency Boiler Repair Appointments
Same-day appointments where engineer availability allows
If your boiler has stopped working, you have no heating, no hot water, or your boiler is showing a fault code, Mr Reactive can help arrange an emergency boiler repair appointment across West Yorkshire. Emergency availability depends on engineer schedules and your location, but we always aim to respond as quickly as possible.
Call 01274 752 852If you smell gas
If you smell gas or suspect a gas leak, do not book a standard boiler repair. Turn off the gas at the meter if safe to do so, open windows, avoid naked flames and electrical switches, leave the property and call the National Gas Emergency Service on 0800 111 999.
Boiler Breakdown Help Across West Yorkshire
A boiler breakdown always seems to happen at the worst time. If your boiler has stopped working, our Gas Safe engineers get heating and hot water back on across Bradford, Leeds, Huddersfield, Wakefield and Halifax — with same-day attendance wherever an engineer is available.
Boiler stopped working
A boiler that has shut down completely — no display, no response — often points to an electrical supply fault, a tripped fuse or a PCB problem. We diagnose the cause before quoting.
Broken boiler, no heating
A broken boiler leaving you with no heating is one of the most common breakdowns we attend. Causes range from pressure loss and pump faults to a frozen condensate pipe in winter.
No hot water
No hot water from a combi boiler is frequently a failed diverter valve, a flow sensor fault or a faulty PCB. Our engineer tests each component and explains the repair.
Boiler not firing
If the boiler will not fire or ignite, the cause is often a faulty fan, ignition lead, gas valve or flue sensor. We carry common parts to fix many breakdowns on the first visit.
For an out-of-hours boiler breakdown, see our emergency boiler repair service. If you smell gas, leave the property and call the National Gas Emergency Service on 0800 111 999 first.

Boiler Repair FAQs
How much does a boiler repair cost?
Boiler repairs at Mr Reactive start from £89. If the repair goes ahead, there is no separate call-out fee. If you choose not to proceed after diagnosis, a diagnostic fee may apply. The final cost depends on the fault, whether replacement parts are required and the repair work agreed before our engineer continues.
Do you offer emergency boiler repair?
Yes. Emergency boiler repair appointments are available across Bradford, Leeds, Huddersfield, Wakefield and Halifax, subject to engineer availability. Call 01274 752852 and we'll let you know the earliest appointment we can offer.
Can you repair my boiler if I have no heating or hot water?
Yes. No heating and no hot water are two of the most common issues we attend. Causes range from pressure loss and ignition faults to diverter valve, thermostat or pump problems. Our Gas Safe engineer will diagnose the fault and explain the repair before continuing.
Are your boiler engineers Gas Safe registered?
Yes. Mr Reactive Ltd is on the Gas Safe Register under registration number 598381. Every engineer carrying out gas work on your boiler is Gas Safe registered. You can verify our registration at gassaferegister.co.uk.
Do you repair combi boilers?
Yes. We repair combi, system and heat-only domestic gas boilers across West Yorkshire.
Which boiler brands do you repair?
We repair all major UK domestic boiler brands including Worcester Bosch, Vaillant, Ideal, Baxi, Viessmann, Glow-worm, Potterton, Alpha, Main, Vokera, Ferroli and Biasi.
Do you repair electric boilers?
No. Mr Reactive repairs domestic gas boilers only. We do not repair electric boilers.
Do you repair commercial boilers?
No. This service is for domestic properties only. We do not repair boilers in commercial premises.
Can tenants book a boiler repair?
Tenants can contact us to report a boiler fault, but the repair must be authorised by the landlord or letting agent before chargeable work begins. We are happy to liaise directly with landlords to arrange the appointment and confirm costs.
Do landlords need a new CP12 after a boiler repair?
A CP12 gas safety certificate is required annually and after certain types of gas work. If a repair affects the gas-carrying components of the boiler, a new check may be appropriate. Our engineer can advise on whether a CP12 should be issued at the same visit.
Is it better to repair or replace a boiler?
For boilers under ten years old with a single fault, repair is usually the most cost-effective option. For older boilers with repeated breakdowns, declining efficiency or unavailable parts, replacement may be the better long-term choice. Our engineer will give you honest advice based on the boiler's age, condition and fault.
What should I do if I smell gas?
If you smell gas or suspect a gas leak, do not book a standard boiler repair. Turn off the gas at the meter if safe to do so, open windows, avoid naked flames and electrical switches, leave the property and call the National Gas Emergency Service on 0800 111 999.
Do you cover Bradford, Leeds, Huddersfield, Wakefield and Halifax?
Yes. Our coverage area is West Yorkshire, with dedicated engineer availability across Bradford, Leeds, Huddersfield, Wakefield, Halifax and surrounding BD, LS, HD, WF and HX postcodes.
Can I book a boiler service at the same time as a repair?
Yes. Many customers combine a boiler repair with an annual service or CP12 gas safety certificate to save on a second visit. Just mention it when you book and we'll allow extra time on the appointment.
Can a leaking boiler be repaired?
In most cases, yes. A leaking boiler is often caused by a failed seal, corroded pipework, a faulty pressure relief valve or a heat exchanger problem. Our Gas Safe engineer will find the source of the leak and advise whether a repair, or in some cases a replacement, is the better option.
Why has my boiler stopped working?
Boilers stop working for many reasons — loss of pressure, a tripped electrical supply, ignition or fan faults, a frozen condensate pipe in winter, or a PCB failure. Our engineer runs a full diagnostic to find the actual cause before quoting the repair.
Why does my boiler keep losing pressure?
Repeatedly dropping pressure usually means a leak somewhere in the system, a failed expansion vessel or a faulty pressure relief valve. Simply re-pressurising the boiler only masks the issue — our engineer will trace and fix the underlying cause.
Do you repair Worcester Bosch boilers?
Yes. Worcester Bosch is the most common brand we repair. Our engineers handle Worcester combi, system and Greenstar boilers, including common fault codes such as EA, A1 and 227.
Do you repair Vaillant boilers?
Yes. We regularly repair Vaillant ecoTEC and other Vaillant boilers, including fault codes such as F22, F28 and F75.
How quickly can an engineer attend a boiler repair?
We aim to attend the same day wherever engineer availability allows, or first thing the next morning. Call 01274 752852 and we'll give you the earliest appointment we can offer.
What is classed as an emergency boiler repair?
A complete loss of heating or hot water, a boiler leak, or any situation where you smell gas is treated as urgent. If you smell gas, leave the property and call the National Gas Emergency Service on 0800 111 999 before booking a repair.
Will I be charged if my boiler cannot be repaired?
If your boiler is diagnosed as beyond economical repair, our engineer will explain why and discuss your options, including replacement. If you choose not to proceed after the diagnostic, a diagnostic fee may apply — this is always made clear before the visit.
