Central Heating in London
A central heating system is more than a boiler. It’s the radiators, the pipework, the controls, the balancing, the inhibitor levels, and how the whole thing is sized to your property. Ilir designs and installs central heating systems across London — from single-radiator additions to full system overhauls in Victorian terraces — and the difference is in the design. Wrong-sized radiators cost you comfort and money for years; right-sized ones disappear into the background and quietly do their job. Ilir uses heat-loss calculations, not guesswork, and balances every system before signing off.

What's in every job
- Heat-loss calculation per room (not guesswork)
- Correct radiator sizing for the room and the boiler
- Smart thermostat installation (Hive, Nest, Tado, Drayton)
- TRVs fitted as standard on new and replacement radiators
- System inhibitor and magnetic filter included
- Full system balance and commissioning
- Power flush quoted separately if existing system needs it
Typical job duration: 1–4 days
