Central heating services starting from £120
Central heating diagnosis and repairs from £120 for the first hour. Most minor valve, balancing, and circulation issues are resolved on the first visit, with fixed quotes agreed before any extra work begins.
FULL HEATING CARE
From replacing noisy circulating pumps and faulty zone valves to balancing radiators and upgrading smart controls, we make sure your entire heating system runs efficiently without cold spots.
01 / REPLACEMENTS
New radiators, modern designer models, and like-for-like swaps, correctly sized for your room BTU requirements and balanced for even heat.
02 / EXTENSIONS & MOVES
Relocate radiators during room renovations or add new heating into cold extensions, with neat pipework altered and fully pressure tested.
03 / PERFORMANCE
Adjusting flow rates across lockshield valves and installing thermostatic radiator valves (TRVs) so every room heats up at the exact same pace.
04 / DIAGNOSTICS
Fixing cold radiator bottoms, air locks, noisy pipe hammering, stuck motorised zone valves, and circulation pump failures.
05 / NEW SYSTEMS
Complete heating designs, new radiator circuits, modern zoned manifolds, and smart thermostat integration for West London homes.
06 / HOT WATER STORAGE
Maintenance, replacements, and repairs for vented and unvented hot water cylinders, immersion heaters, and circulating booster pumps.
RESTORE HEAT FLOW
Cold radiator bottoms and noisy boilers are usually caused by black magnetite sludge. We test your water quality first to recommend the right treatment for your pipework—never pushing an expensive powerflush if a chemical clean is all you need.
The lighter clean
from £250
Cleaner is circulated through the system by your own pump and left to work, then drained and refilled with inhibitor. Right for lightly contaminated systems and as preparation before a new boiler.
The deep clean
from £499
A high-flow pump is connected to the system and each radiator is flushed in turn under pressure, with magnetic capture on the return. Right for heavy sludge, cold-at-the-bottom radiators and older systems.
We check the valves, system balance, pump, pressure and water condition first. Balancing or valve work is often the actual fix, and it costs a fraction of a flush. We'll tell you which yours is before quoting.
Protect & balance
Cleaning the water is step one. Adding high-grade inhibitor chemical, fitting a magnetic filter, and balancing radiator lockshields keeps your heating efficient for years to come.
01 / FILTRATION & DEFENCE
Fitted to your return pipework to capture metallic sludge before it reaches your boiler pump and heat exchanger. Protects critical components and includes a full demonstration. From £295.
02 / CHEMICAL PROTECTION
Professional chemical dosing added directly to your system water to stop internal pipework corrosion and prevent sludge build-up. Essential whenever your heating is drained or flushed.
03 / FLOW & BALANCE
Fine-tuning lockshield valves so hot water circulates evenly across the entire home. Fixes the room that never warms up and stops other rooms from overheating without replacing parts.
