Air source heat pumps in Haslar, done properly
An air-to-water heat pump heats water to a lower temperature than a typical boiler, so radiators may need to be larger to give out the same heat. We check each radiator against the room’s heat loss, and the quote sets it out. The work covers hot water cylinders, radiator systems and air-to-air heat pumps, and the jobs we see most are not knowing whether a grant applies and choosing between air-to-water and air-to-air.
Homes around Haslar usually have room outside for a heat pump, so the design focuses on heat loss and radiators.
Whatever the visit, you get a written record: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. File it with the manual so it’s to hand next time.

Common problems we fix in Haslar
Air-to-air systems interest people who want cooling in summer as well as heating. They warm rooms directly through indoor units, and can cool them when it’s hot. The grant only applies in some cases, so we check first.
Keep an eye out for any of the following:
- Not knowing whether a grant applies
- Wanting to stop using oil, LPG or gas for heating
- Replacing a combi boiler with a heat pump
Every heat pump design starts with a room-by-room heat loss calculation.
What your quote should include

FAQs for Haslar
Does sea air affect air conditioning in Haslar?
It can, as Haslar is within about 1 mile of the sea, where salt in the air is hard on coils and fixings. The outdoor unit position, its fixings and regular servicing all help near the sea.
Can I fit a heat pump in Haslar without planning permission?
That depends on the building and where the outdoor unit goes. The Stokes Bay Conservation Area is close to the centre of Haslar. A heat pump on a house can be permitted development if it meets the conditions, including the MCS noise check, but not within the grounds of a listed building, and in a conservation area the outdoor unit can’t face a road. Where needed, we check with the planning department at Gosport council, typically the authority for Haslar.
What’s the price of a heat pump installation?
For air-to-water, it’s £8,000–£16,000 (0% VAT on homes) before any Boiler Upgrade Scheme grant. Air-to-air systems are priced after a survey, with the VAT confirmed on your quote.
Does servicing affect my warranty?
It can, for some brands. Send us the make and model and we’ll tell you what the manufacturer expects and stick to the interval they set.
Do you work on commercial properties?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size across London and the South East. Let us know who the records should go to.
Can we book visits on a schedule?
Yes. We offer maintenance contracts, set at the interval the system and the manufacturer’s terms need. Each visit is recorded and F-Gas records kept where they apply.
Which accreditations do you hold?
We’re an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We are also Checkatrade members.
The process
We book the visit for a day and time that suit you, and we let you know if plans need to move. When we arrive, we check the job against the survey or the photos you sent. If something is different, we talk it through with you before carrying on. After that, it takes a few days on site, depending on the cylinder, the radiators and the pipework involved. For a place like Haslar, the timing is set with you and the travel is our side of the planning.
- You tell us about the home and what you want from a heat pump.
- We survey for heat loss and look at radiators, cylinder space and outdoor unit options.
- We recommend air-to-water or air-to-air and check the grant position.
- We install the heat pump and connect it up.
- After commissioning, you get the MCS certificate and a handover.
Getting ready for the visit
- Name a contact who can meet us at the agreed time
- Let us know where we can park and unload
- Keep pets and children away from the work area

Looking after it afterwards
Looking after the system is mostly common sense. Our tips:
- Leave space around the outdoor unit
- Book a yearly service
- Store the MCS certificate and warranty documents together
If anything does not seem right after installation, give us a ring on 07833 053749, or email if that’s easier and we will talk it through. A yearly service is a good habit.
Keep radiators and indoor units unobstructed so the heat can get into the room.

What a heat pump looks like in Haslar
The coast is only about 1 mile from Haslar. For a heat pump near the sea, ask about any coastal protection option the manufacturer offers. About 39% of homes in the Haslar area were built before 1919, according to the Valuation Office Agency’s council tax figures, and about 43% of households live in terraced houses, according to the 2021 Census. Older homes can lose heat faster, so a room-by-room heat loss calculation, and sometimes insulation or larger radiators, comes before sizing a heat pump. Terraced houses share walls with neighbours, which helps, but the outdoor unit position needs care with noise next door.
Live in one of the older houses around St Francis? Expect the survey to look closely at heat loss and at the building’s planning status.
