The service

Heating that reaches every room

Central heating and radiator installation covers everything from swapping a single radiator to fitting a complete new heating system. It includes adding radiators to cold rooms, upgrading to larger or more modern radiators, moving radiators during a renovation, and fitting thermostatic radiator valves for better control.

This service is for homeowners with cold rooms, people renovating or extending, landlords updating rental properties, and anyone whose radiators are old, leaking or not giving out enough heat.

Getting it right matters. Radiators need to be sized for the room, the pipework needs to suit the boiler, and the system needs to be balanced so heat reaches every radiator, not just the ones nearest the boiler.

What a poorly performing heating system costs you

Cold rooms, radiators that are hot at the bottom but cold at the top, and a boiler that runs constantly without warming the house are all signs of a heating system that is not working as it should. You pay for the gas either way.

Undersized radiators, sludge build-up and an unbalanced system make your boiler work harder, shorten its life and lead to condensation and damp in cold rooms. Leaking radiator valves can also damage flooring and ceilings below.

Common mistakes we see

  • Fitting radiators that look good but are too small for the room.
  • Adding radiators without checking the boiler can cope.
  • Never bleeding or balancing the system.
  • Ignoring a slow leak from a radiator valve.
  • Fitting new radiators onto a system full of sludge.

In detail

Central heating in more detail

The choices that make a difference to how warm your home feels.

Choosing radiators

Radiators come in single, double and triple panel designs, as well as vertical and towel radiators. The right size depends on the room's dimensions, windows and how well it holds heat. A radiator that is too small will never warm the room properly, however hot the boiler runs.

Thermostatic radiator valves

Thermostatic radiator valves (TRVs) let you control the temperature in each room. They are a simple way to avoid overheating rooms you rarely use and to put the heat where you need it.

New systems and extensions

For a new central heating system or an extension, Ian will consider pipe routes, the boiler's output and how the new radiators connect to the existing system. Where the boiler is old or undersized, replacing it at the same time may be the better option.

System health

If your existing radiators have cold spots or the water is dark when you bleed them, sludge is likely. Ian will check this before fitting new radiators.

Towel radiators and bathrooms

Heated towel rails keep towels dry and warm the bathroom, helping to reduce condensation. They can be plumbed into the central heating, run electrically, or set up to do both. If you're planning a new bathroom, fitting the towel rail at the same time keeps pipework hidden and the finish tidy.

Balancing the system

Balancing means adjusting the valves on each radiator so hot water is shared evenly round the house. Without it, radiators near the boiler get hot quickly while those furthest away stay lukewarm. It is a simple step, but it makes a noticeable difference to comfort and how hard the boiler has to work.

Landlords and rental properties

Tenants notice cold rooms quickly. Replacing tired radiators and fitting thermostatic valves in a rental property can reduce complaints, help tenants manage their heating costs, and lower the chance of damp and condensation damage.

Upgrading old radiators

Old radiators can corrode from the inside, giving out less heat and eventually developing pinhole leaks. Replacing them with modern, correctly sized radiators can make a cold room comfortable. Where possible, new radiators can be chosen to fit the existing pipe positions, which keeps the job simpler and the disruption lower.

Smart controls and thermostats

Good controls let you heat your home when you need it. A programmable room thermostat combined with thermostatic radiator valves gives you control over both timing and the temperature of each room. Ian can advise on controls that suit your boiler and the way your household lives.

Heating for extensions and loft conversions

New rooms need heating sized for their windows, insulation and use. Ian will check whether your boiler has enough output for the extra radiators, plan pipe routes that avoid disturbing finished areas, and connect the new radiators so they heat as well as the rest of the house.

Bleeding radiators yourself

Bleeding a radiator releases trapped air. With the heating off and cool, use a radiator key to open the bleed valve slowly until water appears, then close it. Check the boiler pressure afterwards and top it up if needed. If radiators need bleeding often, there may be an underlying problem worth checking.

What's included in a radiator quote

Your quote will cover the radiators and valves, any pipework changes, draining and refilling the system, adding inhibitor, and balancing. You get a clear quote with no hidden costs.

Questions

Central Heating & Radiators: your questions answered

How much does it cost to fit a new radiator?

+

It depends on the radiator and the pipework needed. You'll get a free, no-obligation quote.

Can you add a radiator to a cold room?

+

Yes. Ian will check your boiler and pipework can support the extra radiator.

Can you move a radiator during a renovation?

+

Yes. Radiators can be repositioned with the pipework rerouted neatly.

Why are my radiators cold at the top?

+

Usually trapped air. Bleeding the radiator often helps. If it keeps happening, there may be a wider issue.

Why are my radiators cold at the bottom?

+

This often points to sludge build-up, which Ian can check and advise on.

How long does a radiator installation take?

+

It depends on the number of radiators and pipework involved. Ian will confirm timings with your quote.

Is the work guaranteed?
