MCS Accredited BUS Grant Eligible ASHP design & install Hybrid systems Existing UFH retrofit 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 ## Most ASHP disappointment is an install problem, not a technology problem. 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. ### Running costs higher than gas 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. ### Lost BUS grant Non-MCS install, missed paperwork, or design deviation from MCS standards means the £7,500 BUS grant is withdrawn, paid back by the homeowner after the fact. ### Cold rooms in winter 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. ### What we see when we're called in to fix a poor ASHP install. - 01Heat-loss based on EPC data instead of a room-by-room MCS-compliant survey. - 02Pump sized to peak demand instead of design demand, cycles aggressively, kills the compressor, kills the SCOP. - 03Emitters left as-is on flow temperatures the pump cannot efficiently produce. - 04Buffer tank or volumiser missing, oversized, or plumbed wrong, destroying defrost performance. - 05No weather compensation curve set on commissioning, so the pump runs at design flow temperature year-round. Our Process ## A meticulous, no-mess method. 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. 01 ### Free in-home survey MCS-compliant heat-loss model, emitter audit, hot-water demand assessment, electrical supply check. No assumptions. 02 ### Design & grant application 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. 03 ### Emitter upgrade (if required) If existing rads or UFH can't deliver at low flow temperature, we upgrade only what's needed, often fewer rads than expected. 04 ### Install & commissioning ASHP installed, pipework lagged, controls configured, weather compensation curve set, SCOP modelled. Documented MCS commissioning sheet. 05 ### Aftercare & service plan Annual service to maintain MCS warranty validity. Same engineers, same number, lifetime of the system. What You Gain ## Measurable outcomes, not vague promises. ### Genuine SCOP 3.8–4.2 territory 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. ### £7,500 off the invoice We are MCS-accredited and submit the BUS grant directly. You see the net price upfront and pay only the difference. ### Future-proof on energy policy Gas boiler installs are on a 2035 phase-out path. A heat pump installed now is the asset you'll keep through the transition. ### Quiet, hidden, reliable Modern inverter-driven ASHPs sit at 35–45 dBA at 3 m, quieter than most fridges. We position units for acoustic neighbourliness as standard. ### Hot water with no boiler Heat pumps produce 50–55 °C cylinder water comfortably, with weekly Legionella cycle. No need to keep a gas boiler 'just for hot water'. ### Documented warranty path 7-year compressor warranty (most ranges), full MCS commissioning pack, service plan to maintain warranty validity. Real protection, not marketing. Technical Detail ## Models, methods, and where the install actually makes the difference. 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. ### Pump selection 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. ### Sizing, design vs peak 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. ### Buffer, volumiser, low-loss header 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. ### Cylinder & hot water 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. ### Controls & weather compensation 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. ### Hybrid systems 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 ## Honest answers, on the record. 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. What does an air source heat pump cost in Cheshire?+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. How much will my running costs change?+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. Will my radiators need replacing?+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. How loud is it?+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. How long does the install take?+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. Is the BUS grant guaranteed?+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. What about hot water?+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. Will it work below freezing?+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. Who services it after install?+We do. Same engineers, annual service to maintain MCS warranty validity, 7-year compressor warranty handled by us with the manufacturer.
