Air Source Heat Pump Installation in Brighton & Hove, BN
EE Renewables Ltd installs MCS-certified air source heat pumps across Brighton and Hove. In a city of converted houses, the first question isn’t which heat pump — it’s who owns the outside space it would sit in. We establish that before quoting, and tell you honestly where the answer doesn’t work. Book a free survey today.
Why install an air source heat pump in Brighton?
Brighton’s housing stock is unusual, and it changes the conversation before you get anywhere near choosing equipment. A very large share of homes here aren’t houses — they’re flats carved out of Regency and Victorian townhouses, often four or five to a building. If you live in one, the outdoor unit has to go somewhere you have a legal right to put it, and that is a freeholder or management company question rather than an installer question.
It’s worth establishing early because it’s the step most likely to add weeks. Ground-floor and garden flats with private outside space are frequently workable. Upper-floor flats face a 0.6 cubic metre permitted development cap against 1.5 for a house, and wall-mounted units above ground floor usually fall outside permitted development altogether.
Lower-ground flats bring a particular technical wrinkle. A lightwell looks like ideal spare space, but it’s an enclosed box of hard vertical surfaces — sound reflects rather than dissipating, so a unit that would comfortably pass the MCS 020(a) noise assessment in an open garden can fail in a well. It’s often still solvable with careful positioning and acoustic treatment, but it needs calculating rather than assuming.
For houses, Brighton is good territory. Terraces through Hanover and Elm Grove, semis in Patcham, Withdean and Portslade, and detached property towards Hove Park and Rottingdean all have workable options — helped by the May 2025 rule change that removed England’s one-metre boundary clearance requirement, so siting is now governed by the noise assessment rather than a fixed distance. Conservation area coverage across the seafront and older centre, and the city’s substantial listed Regency stock, both need checking against your address first.

Heat pump installation cost in Brighton
Access drives more of the price variation here than property size does. Brighton is built on a slope, plenty of terraces have no side access, and getting a cylinder and outdoor unit into a lower-ground flat is a different job from wheeling them down a driveway. The other variable is whether a combi has already displaced the hot water cylinder. Figures below reflect 2026 MCS installer pricing across BN.
| Brighton property type | Typical system size | Installed cost | Cost after £7,500 grant |
|---|---|---|---|
| Ground-floor or garden flat with private outside space | 4–6kW | £7,000–£9,500 | £0–£2,000 |
| 2-bed terrace (Hanover, Elm Grove, Kemptown) | 5–7kW | £8,000–£10,000 | £500–£2,500 |
| 3-bed terrace or semi (Preston Park, Patcham, Portslade) | 8–10kW | £10,000–£13,000 | £2,500–£5,500 |
| 4-bed semi or detached (Withdean, Hove Park, Rottingdean) | 10–14kW | £13,000–£16,500 | £5,500–£9,000 |
Grants & benefits of installing a heat pump in Brighton
£7,500 Boiler Upgrade Scheme grant
Brighton homes replacing a gas boiler or electric heating qualify for £7,500 towards an air source heat pump. We make the Ofgem application as your MCS-certified installer and deduct the grant from your invoice. Landlords can apply on properties they own, which matters in a city with a private rented sector this large, and installation is zero-rated for VAT.
Escape electric storage heating
Brighton’s converted flats contain a great deal of old electric storage heating — expensive to run, awkward to control, and often the reason a property has a poor EPC. Where the outdoor space question can be solved, replacing storage heaters with a heat pump produces one of the largest running cost reductions available from any heating change.
Meet tightening EPC standards
Over 700 privately rented properties in the city have been identified as falling below minimum energy efficiency standards. Replacing fossil fuel or electric resistance heating with a heat pump generally lifts an EPC score, with the strongest gains where insulation is already reasonable. For solid-wall Regency and Victorian stock, we’ll tell you which fabric measures move the rating furthest first.
Support the city’s carbon neutral programme
Brighton & Hove declared a climate and biodiversity emergency in December 2018 in a cross-party commitment, targeting a carbon neutral city by 2030. The council’s more recent Decarbonisation Pathways Study is candid that while it continues to aim for 2030 on its own estate, 2040 looks more realistic for the city as a whole. Domestic buildings are the largest remaining piece either way.
PARTNERS
Brighton’s Octopus Energy trusted renewable energy partners
We’ve spent over a decade in green home energy and we’re MCS-approved installers of Vaillant UK air source heat pumps. We’re also an Octopus Energy Trusted Partner, and at the 2026 Octopus Energy Trusted Partner Awards we were named Solar & Battery Installer of the Year from more than 650 partners nationwide.
Brighton is a well-informed market — a city with its own community energy co-operatives tends to ask sharp questions, which we welcome. Octopus selects, vets and monitors its partners on installation quality and customer service, so the credential is checkable. The partnership also opens up the smart heat pump tariffs that decide whether your running costs genuinely fall.

ASHP running costs and savings for Brighton homeowners
Where you’re starting from decides everything. Under the Ofgem cap for July to September 2026, electricity costs 26.11p per kWh against 7.33p for gas. A heat pump closes that gap by producing three to four units of heat per unit of electricity, so a system running at a SCOP of 3.5 sits close to gas parity on a standard tariff — with design quality deciding which side of the line you land.
The saving comes from the tariff. On a specialist heat pump tariff with cheap off-peak rates, the Energy Saving Trust puts typical annual savings at £200–£400 against gas, and leaving the gas network entirely removes the standing charge too. Brighton’s mild coastal winters help the seasonal figure, since the system spends less of the year working against genuinely low temperatures.
If you’re coming off electric storage heating the numbers are on a different scale entirely. And because a solid-wall conversion flat and an insulated 1930s semi in Patcham behave very differently, we model your property’s real demand at survey rather than quoting a city-wide average.
