Complete Central Heating Systems in Streatham – Free Quotes from Gas Safe Installers
Planning a new central heating system in Streatham? We can pass your enquiry to qualified heating engineers based near Streatham who can survey the property, design a system around it and give you a fixed written price. A full installation starts from a clean sheet — boiler, pipes, radiators, hot water and controls — so nothing is held back by decisions made decades ago.
When a New System Is the Right Call
A repair or boiler swap is often enough, but some homes in Streatham need a complete rethink. Typical reasons include:
- Electric storage heaters that are expensive to run and hard to control
- No central heating at all, or a single gas fire heating the house
- Original pipework with repeated leaks or heavy corrosion
- Rooms added by extensions that were never properly heated
- Radiators that are undersized, mismatched and rusting
- A full renovation with floors already lifted
- Plans to fit a heat pump later and wanting low-temperature-ready radiators now

Central Heating Costs in Streatham
The cost of a new system in Streatham depends on the size of the property, how many radiators are needed, floor construction and the boiler and cylinder you choose. As a rough guide:
| Property | Typical cost in Streatham (inc. VAT) |
|---|---|
| Flat or small 1–2 bed house (5–7 radiators) | £4,000 – £5,500 |
| 3 bed house (8–10 radiators) | £5,500 – £7,500 |
| Larger house with unvented cylinder | £7,500 – £9,000+ |
Homes with solid floors, long pipe runs and bringing in a gas supply can all push prices higher, so weigh up itemised quotes from several local installers.
Approvals for Heating Installations
Gas boiler and flue work requires an engineer registered for the relevant Gas Safe categories. Ask how the installation will be notified under the rules applying where you live. New systems should also include suitable time and temperature controls, with thermostatic radiator valves in individual rooms. You won't usually need planning permission, except where a flue is visible on a listed building or in a conservation area. For local guidance, visit the Greater London Authority website.

Common questions from homeowners
How much does central heating installation cost in Streatham?
A complete central heating system in Streatham typically costs between £4,000 and £9,000, depending on the number of radiators, the boiler and cylinder chosen and how easy it is to run pipework under the floors.
How long does a full central heating installation take?
Most installations take between three and seven working days. Larger homes, solid floors and unvented cylinders sit at the longer end of that range.
Will my floors need to be lifted?
In most homes, some floorboards are lifted to run pipes neatly to each radiator and then re-laid. On solid floors, pipes may be run along walls, in boxing or chased into the wall instead.
Do I need permission to install central heating in Streatham?
Planning permission is not normally required. Ask the Gas Safe installer how a gas boiler installation will be notified under the rules where you live. Check with Greater London Authority before changing a visible flue on a listed property or where local restrictions may apply.
