Boiler repair in Middlesbrough
No heat, no hot water or a boiler that keeps locking out. Tell us what's happening and we'll pass it to Gas Safe registered engineers covering Middlesbrough.
Most Middlesbrough homes depend on a single gas boiler, but 9.4% of households had two or more types of heating at the 2021 Census. If you have a gas fire or electric heaters as well, use them safely while you wait, and keep the boiler switched off if it's leaking.
Before calling, a few checks can save a wasted visit.

Five minutes of checks
Is the gas on? Try the hob. Is the power on at the fused spur? Is the thermostat calling for heat, with fresh batteries? Is the pressure between 1 and 1.5 bar when cold? Our boiler pressure guide covers topping up.
If the boiler shows a fault code, write it down. If it gurgles and stops in frosty weather, the condensate pipe may be frozen outside. Thaw it with warm water and reset.
Common faults in older Teesside systems
Older open-vented systems, typical in semis and terraces, often suffer from sludge, sticking pumps and failing motorised valves. Heating with no hot water, or the other way round, usually points to a valve.
Combis tend to fail on fans, ignition leads, diverter valves and pressure sensors. Most are fixed in one visit if the engineer can get the part.
Renting? Report it, don't fix it
Private tenants, 21% of households, and social tenants, 23.2%, should report heating faults to the landlord in writing. Repairs are the landlord's responsibility. Keep a note of when you reported it and any reply.
Middlesbrough homes and what they need
Victorian and Edwardian terraces
Long pipe runs from a back kitchen boiler to front bedrooms can leave the far radiators cold. That can be sludge or balancing rather than a boiler fault.
Interwar and postwar semis
If water overflows from a pipe outside, the loft tank's float valve or the cylinder's coil may be at fault. Mention it to the engineer when booking.
Newer estates on the southern edge
Modern boilers log faults. Ask the engineer to read the fault history, which can point to a pattern rather than one bad day.

When is it time to replace instead?
If the boiler is past 15 years, parts are scarce or repairs keep coming back, compare the quote against our new boiler cost guide.
