Plumbright Southern offers a full central heating service in Hedge End. We install, replace and repair heating systems, fit underfloor heating, swap radiators and power flush systems full of sludge.
Whether you are heating a home for the first time or adding to an extension, central heating installation means planning the boiler, pipework, radiators and controls together. We size each part for your rooms so the house heats evenly. Read more on our central heating installation page.
Old heating systems can lose heat, leak and struggle to keep up. Central heating replacement swaps out tired pipework, radiators and controls, and often the boiler, for a system that is easier to run. Our central heating replacement page explains the process.
Cold radiators, banging pipes or heating that will not switch on are common signs of a fault. We track down the cause, whether it is a pump, valve, thermostat or air in the system, and fix it. Find out more on our central heating repair page.
Underfloor heating spreads warmth evenly across the whole floor, with no radiators taking up wall space. We fit water based systems in new floors, extensions and existing rooms and connect them to your boiler and controls. See our underfloor heating installation page.
A radiator that is rusty, leaking or too small for the room can be swapped without changing the rest of your system. We drain down, fit the new radiator and valves, then refill and bleed the system. More on our radiator replacement page.
Over time, sludge builds up inside heating pipes and radiators, leaving cold patches and making the boiler work harder. A power flush pushes cleaning fluid through the system to clear it out. Read our power flush page to see if it would help.


Plumbright Southern has installed and repaired central heating in Hedge End for 25 years. Because we are Gas Safe registered as well as plumbers, we can look at the whole system, from the boiler to the last radiator, rather than one part on its own. That matters with heating, where a cold room upstairs might be caused by a pump, a valve or sludge somewhere else in the system.

A radiator that is cold at the top usually has air trapped inside. Bleeding it with a radiator key often fixes it. If it keeps coming back, or the radiator is cold at the bottom instead, there may be sludge or a fault in the system, and our Hedge End team can find the cause.
Our central heating service covers new installations, full replacements, repairs, underfloor heating, radiator replacement and power flushing. Because we are also Gas Safe registered, we can work on the boiler as part of the same job, so the whole heating system in your Hedge End home is looked after by one firm.
Usually, yes. Adding a radiator means running new pipework from the nearest suitable pipe and checking the boiler has enough output to heat the extra room. We look at the whole system before fitting, so the new radiator does not leave other rooms cooler than before.
