Air Source Heat Pump Installation — UK-Wide, Qualified & Priced Up Front
An air source heat pump done properly — surveyed, sized, designed — is a quietly excellent way to heat a home. Done badly, it's an expensive disappointment. The difference is entirely in the design, which is why every your area installation we arrange is MCS-certified and starts with a room-by-room heat-loss calculation.
How a heat pump heats your home
An air source heat pump extracts heat from outside air — it works well below freezing — and concentrates it via a refrigeration cycle into your heating water. Because it moves heat rather than burning fuel, it delivers around 3 units of heat per unit of electricity across a season (the figure quoted as SCOP). The design consequence: heat pumps run cooler than boilers, so radiators are sized larger and the system runs longer and gentler. Comfort is excellent when designed right — steady warmth rather than blast-and-cool cycles.
The machine outside is half the story; the system design is the other half. Heat pumps deliver water at lower temperatures than gas boilers, which suits underfloor heating perfectly and requires radiators sized for the lower flow — sometimes existing ones suffice, often key rooms need upsizing. A hot water cylinder (heat-pump compatible) handles domestic hot water. Get the heat-loss survey, emitter sizing and cylinder right and a your area home runs beautifully on one; skip the design and no brand of hardware rescues it.
Costs, the grant, and honest arithmetic
Installed costs before support typically run £7,000–£14,000 depending on property size, emitter upgrades and cylinder work. The Boiler Upgrade Scheme grant — amount verified at quote time — comes off that for eligible homes in England and Wales, claimed by the MCS installer on your behalf with no paperwork burden on you. Running costs versus gas hinge on the system's efficiency and your electricity tariff; heat-pump-specific tariffs shift the comparison meaningfully, and our running-cost guide walks the real numbers.
Budget in three parts: the heat pump and cylinder, the emitter and pipework upgrades your survey identifies, and the commissioning/controls. The grant reduces the first part for eligible properties — your quote shows before and after. On running costs, be wary of both extremes of claim: a well-designed system on a suitable tariff competes with gas and wins on carbon decisively; a badly designed one on a standard tariff costs more to run. Design quality, not brand brochures, decides which story you get in your area.
Is your home suitable?
The suitability checklist: reasonable insulation (loft and, ideally, wall), space outside for the unit with clearance and a spot that respects neighbours, room for a hot water cylinder, and emitters that can be made to work at lower flow temperatures — meaning some radiator upsizing is common and underfloor heating is ideal. Planning permission is usually not required under permitted development, with rules on unit placement. None of these is exotic; the survey checks all of them and prices what's missing.
Three questions decide it. Can the fabric hold heat? — insulation standards matter more to a heat pump than to a boiler, and improving them first is sometimes the better first spend. Can the emitters run cool? — radiator sizing against a lower flow temperature is the crux of the design, checked room by room. Is there space? — an outdoor unit position and a cylinder location. your area homes pass or fail on specifics, not on age or style; plenty of period properties run happily on well-designed systems.
Installation, MCS and what you receive
A typical installation runs two to five days: outdoor unit positioned and mounted, cylinder installed, any radiator upgrades fitted, pipework and controls connected, then commissioning — where the system is balanced, flow temperatures set, and performance verified. MCS certification wraps the whole process: accredited design standards, the installation itself, and the certificate and handover pack you receive, which the grant, some insurers and future buyers will expect to see.
What lands in your hands at the end: the MCS certificate, commissioning records showing design flow temperatures and settings, the grant handled and deducted, controls configured and explained (heat pumps reward set-and-leave running, not boiler-style on-off habits), and servicing guidance — an annual check keeps efficiency and warranty intact, and our network services what it installs. The handover conversation matters: homes new to heat pumps run them like boilers for the first month and wonder at the bills; run as designed, the economics arrive.

Frequently asked questions
How much does an air source heat pump cost in your area?
Typically £7,000–£14,000 installed before support, depending on property size, radiator upgrades and cylinder work. The Boiler Upgrade Scheme grant — amount confirmed at quote time — reduces that for eligible homes, claimed by the MCS installer on your behalf.
What is the Boiler Upgrade Scheme?
A government grant in England and Wales toward heat pump installation, paid via your MCS-certified installer and deducted from your quote. Eligibility broadly requires replacing a fossil-fuel system in an eligible property. Amounts change over time, so we verify the current figure with every quote — see our scheme guide.
Do heat pumps work in cold UK winters?
Yes — modern units heat effectively well below freezing, and countries far colder than the UK run on them at scale. Efficiency dips on the coldest days, which the design accounts for; the system is sized to hold the house at temperature through a design-condition cold snap.
Will my radiators work with a heat pump?
Some will, some won't — heat pumps run cooler, so radiators need more surface area for the same output. The survey checks room by room; typically a handful of radiators get upsized rather than a wholesale swap. Underfloor heating, where present, is ideal as-is.
Are heat pumps cheaper to run than gas?
It depends on design quality and tariff. A well-designed system achieving good seasonal efficiency, paired with a heat-pump electricity tariff, competes with and can beat gas; a poorly designed one won't. On carbon, heat pumps win decisively either way. Our running-cost guide shows worked examples.
Do I need planning permission?
Usually not — most installations fall under permitted development, subject to rules about unit siting. Listed buildings and conservation areas have extra considerations. The survey flags anything relevant to your your area property before you commit.
Why does MCS certification matter?
It's the accreditation standard for design, installation and paperwork — and it's mandatory for the Boiler Upgrade Scheme grant. Every heat pump installer on this network is MCS-certified; without it there's no grant and no place on our rota.
Are heat pumps noisy?
Modern units are quiet — comparable to a fridge or gentle rain at a few metres — and siting rules keep them considerate of neighbours. The installer positions the unit for both performance and peace; noise complaints track bad siting far more than the technology.
How long does installation take?
Two to five days for most homes: outdoor unit, cylinder, any radiator upgrades, controls and commissioning. You'll have the honest schedule with your quote, including any day the heating or hot water is offline during changeover.
