Before you book: air source heat pump installation in Havant
A heat pump suits most Havant homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
Homeowners across Hampshire can arrange a survey in Havant for a room-by-room design and a written quote before committing to anything. Installers working in Havant plan the order of work so heating and hot water are off for as short a time as practical.
We survey your home, design a heat pump system around its real heat loss, and manage the installation from the first visit to the MCS certificate.
- Houses with reasonable insulation, or a plan to improve it
- Owners and landlords in England and Wales eligible for the Boiler Upgrade Scheme
- Owners who want one contract covering design, fitting and paperwork
What's included
- Outdoor unit, hot water cylinder and weather compensation controls
- System design, unit sizing and a written quote
- Radiator and pipework changes where the design needs them
- Commissioning, handover and a walk-through of the controls
- Boiler Upgrade Scheme application in England and Wales where eligible
Terraced streets in Havant often mean a compact unit position at the rear, so siting and sound levels are checked carefully.
Grants and rules for heat pumps in England
Homes in Havant can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.
What to budget for air source heat pump installation in Havant
Guide prices for Havant and the rest of Hampshire are shown below, installed and inc VAT. We publish ranges rather than a single figure because design details move the price, and the written quote after survey fixes it.

Winter daylight and heating in Havant
Havant sees roughly 7 hours 56 minutes of daylight in late December against 16 hours 31 minutes in June. Milder southern winters suit heat pumps well, though the system is still sized for a cold snap rather than an average day.

- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Air source heat pump installation in Havant: questions
Can you service a heat pump in Havant that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Havant, whoever fitted them. Tell us the make and model when you book.
How soon can you survey a home in Havant?
Survey dates depend on how busy installers are in Hampshire. We offer the next available dates when you enquire and confirm them in writing.
Do you cover Waterlooville as well as Havant?
Yes. We arrange surveys and installation in Waterlooville, which is about 3 miles north-west of Havant, and across Hampshire.
Can I cancel after accepting the quote?
Nothing is ordered until you accept the written quote. Where the contract is agreed away from our premises, for example at your kitchen table, you can cancel within 14 days under the Consumer Contracts Regulations 2013. If you ask us to start sooner and then cancel, you pay only for work done up to that point.
Do I need new radiators for a heat pump?
Not always; many homes keep most of their radiators and change only a few. Because a heat pump runs at a lower water temperature than a boiler, each radiator gives out less heat, so the survey checks every room against its heat loss. Rooms where the existing radiator falls short get a larger one, with a guide price of £250–£450 each, installed and including VAT.
