New Central Heating Systems in Greater London – Planned Around Your Home
Need a complete new heating system in Greater London? We can connect you with heating engineers in towns and villages around Greater London who design and install full wet central heating systems: boiler, pipework, radiators, hot water and controls. Every room is sized individually, rather than guessed from the number of bedrooms.
Where Full Installations Are Common
Most new-system enquiries from Greater London fall into a handful of situations:
- Homes heated by electric storage heaters or panel heaters
- Older properties with a gas fire and back boiler
- Rural cottages being connected to mains gas or switching fuel
- Full renovations where floors and walls are already open
- Systems with corroded steel or leaking copper pipework throughout
- Houses that have been extended so often the old system can't cope
Central Heating Services Across Greater London
- Heat loss survey – room-by-room calculations to size radiators and the boiler
- Boiler and flue – combi or system boiler positioned for the shortest practical flue and pipe runs
- Pipework – flow and return circuits run under floors and through walls
- Radiators and valves – sized to each room, with thermostatic radiator valves
- Hot water – combi, or a system boiler with a vented or unvented cylinder
- Controls and zoning – programmable or smart thermostats, with separate zones for larger homes
- Commissioning and balancing – inhibitor, filter, Benchmark checklist and balanced radiators
Greater London Central Heating Prices
Costs across Greater London are driven mostly by the number of radiators, the floor construction, the boiler and cylinder chosen and whether a gas supply has to be brought in. As a guide:

Approvals and Local Rules
Gas boiler work requires appropriate Gas Safe registration. Ask the installer which notification and energy efficiency rules apply where you live, and how the controls and flow temperature have been designed. Listed and historic properties may need listed building consent before floors are lifted or flues are added to visible walls. Check local planning and conservation guidance on the Greater London Authority website.

Heating questions answered
Do your installers cover rural parts of Greater London?
Engineers in the network may cover rural parts of Greater London. Enter your postcode to check availability; if you are off the gas grid, describe your current heat source so we can look for a suitable specialist.
Can I live in the house while central heating is installed?
Usually, yes. Most installers work room by room so parts of the house stay usable, although you will be without heating and hot water for some of the time and some floors will be lifted.
What size boiler will a new system need?
The boiler is sized from the total heat loss of the home and, for a combi, the hot water flow you need. An oversized boiler wastes energy, which is why a room-by-room heat loss survey matters.
Should a new system be ready for a heat pump?
It is worth considering. Sizing radiators and pipework for lower flow temperatures makes a gas boiler run more efficiently now and means fewer changes if you switch to a heat pump later.
