Everything on the wet side of your heating: boilers, cylinders, radiators, thermostatic valves, pumps, controls, smart thermostats, zoning, pipework and full system flushes. New builds, whole-home replacements, extensions, or fixing a system that's never been quite right.
Homeowners planning extensions or renovations; anyone whose radiators are cold at the top, cold at the bottom, or noisy; anyone still on 1980s controls and 1980s efficiency; landlords wanting a reliable system in their rental property.
During any renovation, extension or bathroom job; when radiators are cold in places they shouldn't be; when the pump or valves sound loud; when energy bills are climbing; when adding a new zone or a smart thermostat.
A heating system isn't just a boiler. The pipework, radiator sizing, flow balancing, filtration and controls decide whether the boiler ever gets a chance to run efficiently. Getting the system right often does more for comfort and bills than just swapping the boiler.
The mistakes that turn small jobs into big bills, and how a qualified engineer keeps them from happening.
Untreated systems fill with iron oxide sludge in 5–7 years. Sludge kills pumps, blocks radiators, cracks heat exchangers, and voids manufacturer warranties.
22mm run where 28mm should have been, or 15mm feeding a radiator that needs 22mm, the system will never balance. Symptom: one room always cold.
A simple programmer and one room thermostat wastes gas heating rooms you're not in. Zoned controls and modern thermostats often pay for themselves in a couple of winters.
Bolting a new radiator onto old sludgy pipework usually just makes the balance worse. It needs a flush and a rebalance, not just a new panel on the wall.
We measure heat loss room by room, check pipe sizing, water pressure and gas supply, and talk through what you want the system to actually do.
Written quote with everything included, boiler, radiators, valves, flush, filter, controls, disposal and certificates. No day-rate surprises.
Pipework, radiators, cylinders and boiler installed to Building Regulations. Systems flushed and dosed with inhibitor before commissioning.
Every radiator balanced, flow temperatures set, controls programmed with you, and readings recorded.
Gas Safe and Building Regulations notification, manufacturer warranty registration, and our 2-year workmanship guarantee.
Correct sizing and balancing means every radiator does its job, no more freezing bedroom above a boiling lounge.
A properly balanced, filtered, condensing system runs at its rated efficiency. That directly reduces your gas bill.
Magnetic filter and inhibitor keep the water clean, which keeps pumps, valves and heat exchangers alive for far longer.
No more banging pipes, whining pumps or gurgling radiators, signs of poor balance, air, or sludge that a proper install eliminates.
Zoned controls, learning thermostats and multi-room set-ups fitted and configured, you actually use them, not fight them.

Materials, methods and variations, the specifics that separate a proper install from a rushed one.
A chemical flush cleans a reasonably clean system before a new boiler. A power flush uses a high-flow pump to strip out years of iron oxide sludge, the right call when radiators are visibly cold at the bottom or the system has never had a filter. We'll tell you which one your system actually needs.
Modern low-content radiators heat up faster and use less water. Thermostatic radiator valves (TRVs) on every room except the one with the wall thermostat let each space set its own temperature, cheap, effective, and required by Building Regulations on new installs.
Simple programmer + wall stat is legal but rarely optimal. Two-zone controls (upstairs/downstairs, or hot water separate from heating) and modern smart thermostats give real control over what you pay to heat.
Combi for smaller homes with one bathroom; system boiler with an unvented cylinder for family homes running multiple showers; regular where an existing loft tank stays. We spec what your actual demand needs, not what's easiest to sell.
Common in extensions and kitchen renovations, underfloor in the new space, radiators everywhere else, run from one boiler through a manifold and separate zone controls. We install and commission both sides.
It depends on the number of radiators, pipework runs, boiler type and controls. We do a free survey and give a fixed written quote before anything is booked, no ballpark surprises.
A typical family-home install is 3–5 working days. Larger properties or system-type changes take longer; we give you an exact expected duration on the quote.
Only if the system is heavily contaminated (cold-bottom radiators, black water, sludge visible on a magnet). Otherwise a proper chemical flush plus a magnetic filter is enough. We tell you which after inspecting.
Yes, supplied and configured, or we install a unit you've already bought. Wiring is checked against your boiler and existing controls so it actually works reliably.
For access and decisions, yes. We can work while you WFH, everything is dust-sheeted and cleaned up daily.
Yes. 2 years on workmanship, plus manufacturer warranties on the boiler and controls.
Yes, we run wet underfloor and radiator hybrids from a single boiler through a manifold and zone controls. See our underfloor heating page for detail.
Yes, all removed items and packaging go with us on the day.
