Cheshire's Specialist UFH Service
MCS-accredited heat pump design and installation that actually delivers the running costs the brochure promises, sized to your real heat loss, paired to your existing or new emitters, and supported by the same engineers for the life of the system. £7,500 BUS grant applied directly against your invoice.

Overview
An air source heat pump is the most efficient way to heat a UK home today, but only if it is correctly sized, correctly paired with your emitter system, and correctly commissioned. The same heat pump, on the same house, can run at a Seasonal Coefficient of Performance (SCOP) of 4.2 or 2.4 depending entirely on the install. We design for the higher number, every time.
We install Mitsubishi Ecodan, Vaillant aroTHERM plus, Daikin Altherma, and Samsung EHS air source heat pumps for retrofit and new-build Cheshire properties. Every install is preceded by a full heat-loss survey, an emitter audit, and a documented design, because the only way to land the headline running costs is to specify the pump against the actual heat loss and the actual emitters, not the floor area on a Rightmove listing.
If you are replacing an oil boiler, off the gas grid, planning a renewables upgrade, or simply tired of gas price volatility, this is the right time to model the numbers properly. We will give you the honest answer about payback, SCOP, grant eligibility, and whether your current emitters are up to it, before we ever quote.
The Cost of Getting It Wrong
Heat pumps work. The bad headlines almost always come down to undersized emitters, oversized pumps, missed insulation, or rushed commissioning. The technology in your neighbour's failed install is the same technology in the install down the road that works beautifully, the difference is the design.
An ASHP running at flow temperatures above 50 °C is hauling a SCOP below 3. At today's electricity prices that costs more to run than the gas boiler it replaced.
Non-MCS install, missed paperwork, or design deviation from MCS standards means the £7,500 BUS grant is withdrawn, paid back by the homeowner after the fact.
Sized at peak load but paired with rads that can't deliver at low flow temp, homeowner runs supplementary electric heaters and pays the bill twice.
Heat-loss based on EPC data instead of a room-by-room MCS-compliant survey.
Pump sized to peak demand instead of design demand, cycles aggressively, kills the compressor, kills the SCOP.
Emitters left as-is on flow temperatures the pump cannot efficiently produce.
Buffer tank or volumiser missing, oversized, or plumbed wrong, destroying defrost performance.
No weather compensation curve set on commissioning, so the pump runs at design flow temperature year-round.
Our Process
Every project is handled by the same engineers, from first survey through final commissioning, and we're the team you'll call for service for the lifetime of the system.
MCS-compliant heat-loss model, emitter audit, hot-water demand assessment, electrical supply check. No assumptions.
Heat pump model, position, pipework, controls, buffer/volumiser, hot water cylinder. We submit the BUS grant on your behalf and apply it to your quote.
If existing rads or UFH can't deliver at low flow temperature, we upgrade only what's needed, often fewer rads than expected.
ASHP installed, pipework lagged, controls configured, weather compensation curve set, SCOP modelled. Documented MCS commissioning sheet.
Annual service to maintain MCS warranty validity. Same engineers, same number, lifetime of the system.
What You Gain
When designed against the actual heat loss with the right emitters and weather comp, modern ASHPs deliver 3.8–4.2 SCOP, significantly lower running cost than gas at current tariffs.
We are MCS-accredited and submit the BUS grant directly. You see the net price upfront and pay only the difference.
Gas boiler installs are on a 2035 phase-out path. A heat pump installed now is the asset you'll keep through the transition.
Modern inverter-driven ASHPs sit at 35–45 dBA at 3 m, quieter than most fridges. We position units for acoustic neighbourliness as standard.
Heat pumps produce 50–55 °C cylinder water comfortably, with weekly Legionella cycle. No need to keep a gas boiler 'just for hot water'.
7-year compressor warranty (most ranges), full MCS commissioning pack, service plan to maintain warranty validity. Real protection, not marketing.
Technical Detail
The compressor in the box matters less than the design around it. Here is what actually decides whether an ASHP performs in a Cheshire home, and where the variation across our installs comes from.
Mitsubishi Ecodan R32 (5/8.5/11.2/14 kW) is our default for most retrofit and new-build. Vaillant aroTHERM plus for higher flow temperature retrofits where emitter upgrades aren't viable. Daikin and Samsung specified where the project demands it.
We size to design heat demand at the local design temperature (-3 °C in Cheshire), not at the historical low. Oversized pumps short-cycle, undersized pumps stutter. Correct sizing is the single biggest determinant of SCOP.
Most installs need a small volumiser, not a buffer. Buffers in the wrong place destroy defrost performance and SCOP. We pick the right hydraulic separation per system, not a default.
Unvented cylinders sized to household demand with high-output coil for ASHP duty. Typical 4-bed: 210–250 L. Weekly Legionella cycle scheduled overnight to off-peak tariff where applicable.
Manufacturer control plus optional smart integration. Weather compensation curve set on commissioning and adjusted at first-winter service. Without weather comp, you're throwing efficiency away.
Where a building cannot economically reach 100% heat pump (very high losses, listed property constraints), we install hybrid systems, ASHP for the bulk load, gas boiler topping for design peaks. Cheaper to run than gas-only, easier to fund than full electrification.
FAQs
The questions Cheshire homeowners and contractors ask us most before a job. If yours isn't here, call 0161 531 1141, we'll answer it plainly.
Typical 4-bed install: £10,500–£14,500 net of the £7,500 BUS grant. Gross before grant: £18,000–£22,000. We submit the grant on your behalf, so the figure you see and pay is the net figure.
Depends entirely on what you're replacing. Oil → ASHP: typically 40–55% lower annual running cost. Gas → ASHP: at current tariffs, 5–25% lower when properly designed. We model your specific numbers at survey.
Sometimes one or two, rarely all. We audit your existing rads at survey and tell you exactly which need upsizing. Many Cheshire homes need only the kitchen and one upstairs rad swapped.
Modern inverter ASHPs run at 35–45 dBA at 3 m, quieter than your fridge in a quiet kitchen. We model acoustic impact at the nearest window and the neighbour's boundary as standard.
Typical install: 1–5 working days on site, with most jobs completed in 2–3 days. New-build: integrated into the build programme. Emitter upgrades, if required, add 1–2 days.
It is currently available to all eligible homeowners until March 2028 at £7,500 per property. We confirm eligibility at survey and submit the application, we have a 100% approval rate to date.
Heat pumps comfortably deliver 50–55 °C cylinder water with a weekly Legionella cycle. We typically install a 210–250 L unvented cylinder for a 4-bed family home.
Yes, modern ASHPs operate down to -25 °C ambient with progressive output reduction. We design for the -3 °C Cheshire design temperature with margin. We have units installed across the area performing well through every winter we've installed in.
We do. Same engineers, annual service to maintain MCS warranty validity, 7-year compressor warranty handled by us with the manufacturer.
