From cold rooms in converted flats to outdated controls, these are the issues residents across the Square Mile bring to us most often.
Common in office-to-residential conversions near Moorgate — a room that was never properly connected to the main system.
An ageing system in Barbican and older buildings near St Paul's can waste energy and struggle to heat every room evenly.
Basic dial thermostats offer no room-by-room control, wasting energy heating rooms you're not using.
Some flats were fitted with an undersized system from the start, struggling to keep up with demand.
A complete process, from assessing your existing system to a fully tested, certified installation.
We assess your existing setup, property layout and heating demand, then agree a fixed price before any work begins.
Radiator positions, pipe runs and zoning are planned to suit your property, including any converted or extended space.
Pipework, radiators and controls installed to specification, connected to your boiler or new system.
Full system flush and heat-up test, Gas Safe certification where applicable, and a walkthrough of your new controls.
From extending an existing system to a full new installation, matched to your property.
A complete system designed and installed from scratch, including boiler, radiators, pipework and controls.
Extending your existing heating into a converted room or previously unheated space.
Smart thermostats and zone valves fitted to give room-by-room control and reduce wasted energy.
A properly designed heating system changes how your home feels, every day of the year.

“One bedroom in our converted flat near Moorgate had no heating at all. Team extended the existing system properly, radiators fitted neatly, works perfectly now.”
“Full new system installed in our Barbican flat, old setup was hopeless. Zoned properly with a smart thermostat, huge improvement in comfort and bills.”
“Extended heating into an extra room in our flat near St Paul’s, engineer designed the pipe runs cleanly and it heats evenly with the rest of the flat.”
A new system for a smaller flat starts from £3,500, a full system for a larger flat or maisonette from £5,200, and extending an existing system or adding smart controls from £650.
Exact pricing depends on property size and scope, and is fixed before work begins.
