Boiler Repair Middlesbrough

Quick answer: Boiler repairs start from £75 including diagnosis. Most repairs are completed the same day. If your boiler has stopped working, try resetting it first (hold the reset button for 10 seconds). If that doesn’t work, call us.

Before You Call - Things to Try

Sometimes a boiler fault is easy to fix yourself:

Try the reset button - Most boilers have a reset button. Hold it for 5-10 seconds. If the boiler fires up, great. If it cuts out again quickly, there’s an underlying fault.

Check the pressure - Look at the pressure gauge. If it’s below 1 bar, the boiler won’t fire. You can usually top up using the filling loop (the braided hose underneath).

Check the thermostat - Is it set correctly? Are the batteries dead?

Check the condensate pipe - In cold weather, the condensate pipe (white plastic, runs outside) can freeze. Pour warm water over it to thaw.

Check for error codes - If your boiler shows an error code, look it up in the manual or Google it. Some are simple fixes.

If none of that helps, call us.

How Much Does a Boiler Repair Cost?

Common Repairs	Typical Cost
Minor fault (reset, pressure issue)	£75 - £100
Diverter valve replacement	£180 - £250
PCB (circuit board) replacement	£300 - £450
Pump replacement	£250 - £350
Heat exchanger replacement	£400 - £600
Fan replacement	£200 - £300
Gas valve replacement	£250 - £350

These are typical prices for parts and labour. Exact costs depend on your boiler model. We’ll always quote before starting work.

Repair vs replace? If the repair is over £400 and your boiler is more than 10 years old, it may be worth considering a new boiler instead. We’ll give you honest advice.

Common Boiler Problems

No heating or hot water

Usually the diverter valve (switches between heating and hot water), pump, or a control board fault. Sometimes just low pressure.

Boiler keeps cutting out

Often low pressure, blocked condensate pipe, or a faulty PCB. Can also be overheating if the system is sludged up.

Boiler makes banging noises

Called “kettling” - usually limescale or sludge in the heat exchanger. May need descaling or a power flush.

Boiler leaking water

Internal seals, heat exchanger crack, or pressure relief valve releasing. Needs inspection to identify the source.

Error codes showing

Each manufacturer uses different codes. Common ones indicate ignition failure, flame loss, or sensor faults. We can diagnose from the code.

Pilot light won’t stay on

Thermocouple or gas valve issue on older boilers. Modern boilers don’t have standing pilot lights.

Pressure keeps dropping

Usually a leak somewhere in the system (not always visible) or a failed expansion vessel.

Frequently Asked Questions

How quickly can you come out?

We aim for same-day or next-day for repairs. Availability varies, so call to check. Genuine emergencies (no heating in cold weather with vulnerable people) are prioritised.

Is the callout included?

Yes - the £75 minimum covers callout, diagnosis, and minor repairs. More complex repairs are quoted based on parts needed.

What if my boiler can’t be repaired?

We’ll tell you honestly. If repair isn’t economical, we’ll explain your options for replacement. We’ll never push a new boiler if a repair makes more sense.

Do you guarantee repairs?

Yes - 12 months on parts and labour for all repairs we carry out.

My boiler is under warranty - can you still repair it?

If it’s under manufacturer warranty, contact the manufacturer first as the repair may be covered. If they can’t help quickly and you need heat, we can repair but it may affect remaining warranty.
