Heating engineers in Norwich
Cold radiators, noisy pipes or a new system: tell us the job and we pass it to heating engineers who work in your part of Norwich.
Not every heating problem is the boiler. In older Norwich houses the pipework, radiators and controls are often decades older than the boiler on the wall, and that's where many faults start.
A good heating engineer looks at the whole system: how water moves round it, how clean it is, and whether the controls make sense for the way you live.
Norwich at a glance
- Water hardness
- Hard to very hard. Anglian Water, which supplies Norwich, says all the water in its region is classed as hard to very hard because it picks up chalk as it moves through the ground. Source
- How homes are heated
- In the Norwich City Council area, 75.7% of households heat with mains gas only and 10.6% with electricity only. 2.4% (1,573 homes) use a communal or district heat network, against 0.9% across England. Oil-only heating is 0.2%, or 142 homes. Source
- Energy ratings
- About 44% of homes with an EPC in Norwich are rated band D or below (median score 70, band C), against 47% across England. Based on certificates lodged in the 10 years to March 2025. Source
Radiators cold at the bottom
A radiator that's hot at the top and cold at the bottom is usually full of sludge, a mix of rust and debris from steel radiators. A power flush or chemical clean followed by a magnetic filter usually fixes it.
Norwich water is hard, so if the system has ever been topped up a lot because of a leak, scale may be adding to the problem. Fix the leak first or the clean won't last.
Balancing the system
If the radiators near the boiler roast while the far rooms stay cool, the system needs balancing. The engineer adjusts the lockshield valves so each radiator gets its share. It's cheap and often overlooked.
Our guide on how to bleed a radiator covers the one job you can easily do yourself first.
If your flat is on a heat network
About 1,570 Norwich households get their heat from a communal or district network. In those homes you don't have a boiler; you have a heat interface unit, and the network operator or your landlord usually maintains it. Check your lease or tenancy before calling anyone in, as an outside engineer may not be allowed to touch it.
Upgrades that make a difference
Thermostatic radiator valves on every radiator except the one with the room thermostat, a programmer you actually use, and a weather compensation setting on a modern boiler all cut gas without changing the boiler.
Norwich homes and what they need
Interwar and postwar semis
Some still have 1960s or 1970s microbore pipework, which blocks easily with sludge. A flush helps, but repeated blockages can mean replacing sections.
Victorian terraces inside the ring road
Pipes buried in solid walls or under suspended floors make leaks hard to trace. Ask about a pressure test before lifting floorboards.
Bungalows on the city edge
Pipes often run through the loft. Make sure they are lagged, because a burst pipe over a bedroom ceiling in January is an expensive repair.
Areas covered
Engineers who cover Norwich work across areas including Eaton, Thorpe St Andrew, Hellesdon, Sprowston, Costessey, Mile Cross, Earlham, Lakenham, Taverham and Drayton.
Questions people in Norwich ask
Must a central heating engineer be on the Gas Safe Register?
Only for work on gas appliances or gas pipes. Radiators, pipework and controls on the water side don't need Gas Safe, but many heating engineers are registered anyway.
