A heat pump pulls more heat from the air than the electricity it uses, so running costs sit below gas. You won't pay VAT on installation, and the Boiler Upgrade Scheme can take up to £7,500 off the install for eligible homes in England and Wales. Pair it with solar panels and some of that electricity is free too.
The Boiler Upgrade Scheme pays up to £7,500 toward an eligible air source heat pump in England and Wales (gov.uk). It comes off your quote before you pay, and we handle the paperwork.

3 to 4 units of heat per 1 unit of electricity. A heat pump moves heat rather than generating it, which is why running costs sit below a gas or oil boiler.
All three brands we install operate down to -25°C. A typical UK winter barely drops below freezing, so a properly-sized heat pump keeps up on the coldest mornings.
Yes. Central heating and hot water come from a single unit. No separate boiler, no second energy source.
The Boiler Upgrade Scheme takes up to £7,500 off the upfront cost for eligible homes in England and Wales. We sort the Ofgem application. After that, lower running costs do the rest.
Yes. Heat pumps run on electricity, so generating your own with solar panels brings running costs down again.
A gas boiler typically lasts 12 to 15 years. Heat pumps have fewer moving parts and routinely run for over two decades.
Heat pumps work well in some homes and poorly in others. If yours matches the left column on most rows, you're a strong candidate.
| Strong fit | Less of a fit | |
|---|---|---|
| Insulation / EPC | EPC C or better. Cavity-wall and loft insulation done, draughts sealed. | EPC F or G with uninsulated solid walls and single glazing. Worth doing the insulation first. |
| Property type | Detached, semi-detached, end-of-terrace, bungalow, or a flat with outdoor space. | Listed building with planning restrictions on outdoor units, or a flat where the freeholder won't consent. |
| Outdoor space | Garden, side passage or flat-roof terrace with a ~1m × 0.5m clear footprint and airflow. | Genuinely no outdoor space, or a dense terrace without permitted-development rights. |
| Current heating | Oil, LPG, electric storage, off-grid, or an old G-rated gas boiler near end of life. | Brand-new A-rated combi installed in the last year or two, and no carbon or bill-cutting urgency to switch now. |
| Radiators | Modern rads sized for ~50°C flow (most homes since 2000), or you're OK upsizing two or three. | Tiny micro-bore rads throughout, and no budget or appetite to upsize the two or three the survey would flag. |
| Hot water storage | Airing cupboard or loft space for a 150–300L cylinder, sized to household. | Compact combi-only flat with genuinely no space for a cylinder, not even in a loft or under the stairs. |
| How long you'll stay | 10+ years. Running-cost savings need time to pay back the higher upfront cost. | Selling within a year or two, and not recovering the upgrade cost in the asking price. |
| Tariff flexibility | Happy to switch to a heat-pump tariff like Octopus Cosy or EDF GoElectric Heat Pump. | Locked to standard variable electricity, with no smart meter and no plans to fit one. |
Published figures for the models we install run from about 35 dB(A) at 1 m in Quiet Mode up to the low 50s dB(A) at 1 m when a larger unit is working hard in winter. The layout still has to pass an MCS noise check at the neighbour’s window. Use the controls below to see how distance changes what you hear.
At 5m from the unit on low load (most of the year), across most gardens.

From your first quote to a working heat pump in around two weeks. We handle the paperwork, the grant application, and the install.
A few questions about your property, current heating, and what matters to you. You get an initial quote straight away.
An engineer visits to check outdoor space, pipework, electrics, and radiator sizing. Your fixed price is confirmed after the survey.
Dates confirmed upfront, heating off briefly during changeover, never without hot water overnight. We walk you through everything at handover.
Flexible finance
Apply the BUS grant first if you qualify (up to £7,500), then spread the rest with no deposit required. Pay monthly over a term that suits your budget, finance from 9.9%APR Representative. Subject to status and affordability.

Yes. Clear terms, fixed repayments, no hidden fees, all under FCA consumer-credit rules.
Straight answers on suitability, install times, radiators, and what life with a heat pump is really like.
Yes. Modern heat pumps operate down to -25°C outside, and most still deliver full rated output at -10°C. Typical UK winters sit between 0°C and 5°C, so the unit spends most of the year well inside its comfortable range.
Efficiency does dip on the coldest days, that's normal physics, but a properly sized system is designed around peak demand at the coldest temperature your area sees. So when a real cold snap hits, the heat pump still keeps up.
The Boiler Upgrade Scheme pays up to £7,500 toward an eligible air source heat pump in England and Wales when you replace fossil fuel or electric heating and meet the published rules. The grant comes off your total cost upfront, before any finance is applied, not as a rebate later. Eligibility depends on your property, your EPC, and your existing heating system, all of which we check during the survey before submitting the application for you.
No, not in normal use. Manufacturer-published sound pressure for the air-to-water models we install is typically 25-38 dB(A) at 3 metres on low load (Samsung Gen 7 R290 in Quiet Mode sits in the high 20s at 3 m, Vaillant aroTHERM plus 5 kW at 36 dB(A)). Your install needs an MCS noise assessment for permitted development, which we run before booking. See our MCS 020 guide and the ruler on our heat pumps page.
Usually no. Heat pumps run cooler than a boiler, around 35°C to 45°C at the radiators instead of 60°C+. That means each radiator has to be big enough to heat its room at the lower temperature. Some already are. Some need swapping for a bigger panel.
In practice, most homes keep most of their radiators. A heat loss survey goes room by room and tells you exactly which ones need to change before anything gets ordered.
Around two weeks from quote to install. The fitting itself takes 2 to 4 days on site. A straight swap where your radiators are already compatible sits at the shorter end. If you need a new hot water cylinder, larger radiators, or extra pipework, it stretches to the full four days. Your heating is off briefly during the changeover, and you'll have hot water back before the end of the day.
Domestic air source heat pumps run from 3.5 kW to 16 kW. The right size depends on heat loss: floor area, insulation, glazing, and your area's coldest typical temperature. A well-insulated 3-bed semi usually lands between 6 and 10 kW. Oversizing causes cycling and inefficiency; undersizing means struggling on cold days. A heat loss survey pins the number before anything gets ordered.
Usually not. Most domestic heat pump installs count as permitted development in England, Scotland and Wales, so no planning application is needed. There are conditions on the unit's size, position, and noise that vary slightly by nation, and listed buildings or conservation areas always need separate consent.
From 28 May 2026, MCS 020 is the only certification route for permitted development in England. We'll assess your specific property during the design stage and let you know what applies.
A gas boiler delivers roughly 90% efficiency; about 10% is lost up the flue. A heat pump moves heat from outside air, so for every 1 unit of electricity it draws you get back 3 to 5 units of heat. Lower flow temperatures run more efficiently: 35°C beats 55°C. Check any model's SCOP in the MCS Product Directory; pairing with solar or a smart tariff stretches savings further.
Yes, the two stack. The Boiler Upgrade Scheme grant of up to £7,500 comes off the headline install price first. Your finance agreement then covers what's left after the grant, not the full sticker price.
That means smaller monthly payments than you'd see without the grant. We confirm grant eligibility during the survey and apply it before any finance figures get quoted on your heat pump proposal.
Yes, when you apply. Getting a heat pump price does not touch your credit file. Applying for finance does: it runs a full credit check recorded on your file. You can apply online for an immediate decision, or we take you through it, so the check only happens once you choose to proceed. See our finance page for how it works.
