Heating Engineer Brighton: Radiators & Central Heating

Around 2,800 Brighton and Hove households had no central heating at all in 2021, and another 14,000 or so relied on electricity alone. Many of those homes are bedsits and flats in converted houses that were never plumbed for a wet system.

For everyone with a boiler, most heating calls are about radiators that won't warm up, noisy pipes and systems that have never been cleaned.

Brighton at a glance

Homes in converted houses: 19.6% of Brighton and Hove households (23,803) lived in part of a converted or shared house in 2021, and 27.6% in a purpose-built block. Together with other flats, about half of all homes are flats. Source
How homes are heated: 75.3% of households heat with mains gas only, 11.9% with electricity only and 1.6% from a heat network. 2.3% (2,844 homes) have no central heating, and oil-only heating covers about 200 homes. Source
Water hardness: Southern Water says most of the water it supplies is hard because it comes from underground chalk aquifers with high levels of calcium. Source
Energy ratings: About 51% of homes with an EPC in Brighton and Hove are rated band D or below (median score 68, band D), against 47% across England. Based on certificates lodged in the 10 years to March 2025. Source

Cold spots and sludge

A radiator that is cold at the bottom and warm at the top usually has sludge in it. One that is cold at the top has air, which our guide on how to bleed a radiator fixes in a few minutes.

If several radiators are cold at the bottom, ask for a power flush or a chemical clean, followed by a magnetic filter so it doesn't build up again. Chalk water from Southern Water adds scale to the mix in older systems.

Adding central heating to a flat

Going from storage heaters to a wet system in a converted flat means finding a route for a gas supply, a flue and pipework, often through floors you share with neighbours. Ask a heating engineer to survey before you assume it is possible.

In some flats, modern electric heaters or an air-to-air heat pump cost less to install and avoid the flue question altogether.

Balancing a tall house

Four-storey houses lose warmth up the stairwell, and the top rooms often run cooler. An engineer can balance the system by adjusting lockshield valves so water reaches every radiator, and fit thermostatic valves on each one.

Brighton homes and what they need

Flats in converted Regency and Victorian houses

Pipework from the original conversion is often surface-run or buried in screed. Ask for any leaks under floorboards to be traced before the engineer starts lifting a neighbour's ceiling.

Victorian terraces on the hills

Microbore pipes from a 1970s or 1980s install block easily. Replacing the worst runs can do more than a flush.

Interwar semis in the northern suburbs

Undersized radiators from an early install can leave bedrooms chilly. Upsizing them now also prepares the house for a heat pump.

Areas covered

Questions people in Brighton ask

Does a heating engineer need to be Gas Safe registered?

Only for work on gas appliances or gas pipework. Radiator and pipework jobs don't need it, but many heating engineers hold both.

Is a power flush worth it on an old system?

If several radiators have cold bottoms and the water from a bleed valve runs black, usually yes. If the system is mostly microbore pipe, ask whether a chemical clean through the system is safer, since a full flush can expose weak joints.
