Air source heat pumps for homes and businesses in Hassocks
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 anything that needs changing is in the quote. If you are dealing with replacing a combi boiler with a heat pump and radiators that may be too small for a heat pump, we can sort it out.
Homes around Hassocks usually have space for an outdoor unit and a hot water cylinder, so heat loss, radiators and the electrics are what we check.
Equipment warranty comes from the manufacturer, on its own terms, and we explain those terms on your quote. Each brand sets its own conditions, and we are happy to talk you through them.

Rented and managed buildings
Portfolio owners often want one contractor and one number. We work across London and the South East, so work at different addresses can be planned together and kept on a regular cycle.
When the building owner and the occupier are different, the lease or tenancy agreement normally sets out who maintains what. We are happy to deal with either side, and the paperwork can go to both.
How the visit works
We keep the work area tidy as we go, with dust sheets down and offcuts and packaging cleared up. If we need to drill through a wall, we agree the spot with you first. On site, it takes a few days for most air-to-water installations, with air-to-air systems often quicker. Everything the job in Hassocks needs is worked out beforehand.
- First we find out about the property, the heating you have now and what you are hoping for.
- On the visit we calculate what every room loses on a cold day, then check the radiators, room for a cylinder and outdoor unit options.
- A fixed-price quote follows, setting out the system, any grant that applies and the VAT.
- Fitting day: the outdoor unit is placed, the indoor side connected and the controls set up.
- Commissioning, MCS certification and a handover of the controls finish the job.
How to prepare
- Let us know if the building has a permit or sign-in process
- Mention any roof access, ladders or high-level work
- Name a contact who can meet us at the agreed time
How to get a quote
Getting a quote is straightforward. Send a few details and pictures, and we reply the same working day. If we need to see the property first, we book a survey at a time that works for you.
Advice
Questions from Hassocks
Do you cover Hassocks for air source heat pumps?
Yes, Hassocks is within the area we cover. To start, give us a ring on 07833 053749 or fill in the contact form with a few photos.
Can I get the Boiler Upgrade Scheme grant in Hassocks?
Yes, if the home and the heat pump meet the scheme’s rules: Hassocks is in England, where it applies. The amount depends on the type of heat pump, and the survey confirms which applies. You don’t apply yourself: the MCS certified installer does, which is us.
Who has to arrange F-Gas leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
Can you look at a system you didn’t fit?
Yes. Systems fitted by other companies are fine, on all the main brands. Send us the make and model, and any records you have.
Do I get paperwork after the visit?
Yes. Each visit is written up, and any work on the refrigerant circuit goes in the F-Gas records. File them with the system’s paperwork.
Can we book visits on a schedule?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Every visit is recorded and F-Gas records kept where they apply.
Do I need to service the system to keep the warranty?
It depends on the manufacturer’s terms. Some warranty terms require the system to be serviced regularly by a qualified engineer, so it’s worth checking. Either way, keep a record of every service.
Fixed-price quotes for air source heat pumps in Hassocks
You’ll get a fixed price before work begins. It takes into account:
- The type of system, from a single split to a larger system
- What state the existing equipment is in
- How far the pipework has to run, and where
The price reflects the work, not guesswork. That is why every job is looked at first, and why the quote is fixed before work begins.
Before you get in touch
Good pictures often save a visit. The most useful are:
- The paperwork from the last service, if you have it
- A close-up of the unit’s label showing the model number
- The postcode and whether it’s a home, flat or business
Every quote starts with a look at the job, from a site survey or, where the job is straightforward, from pictures and measurements. After that, we send a fixed price before any work starts.
After we have gone
Systems last better with the right care. We suggest:
- Let the heat pump run steadily, as set up at handover
- Keep to regular servicing
- Do not block radiators or indoor units with furniture
Now and then in cold weather, the outdoor unit defrosts itself. You might see steam or hear the unit change note and it’s part of how the system works.
A well-insulated home helps a heat pump because it reduces the heat the system needs to supply.

At about 40 miles from central London, Hassocks sits inside the area we cover across London and the South East.

Homes of that age often have cavity walls that may or may not be insulated, which the survey checks. Houses usually have space for an outdoor unit and a hot water cylinder.
Homeowners near Hassocks station often ask whether a heat pump can take over from the boiler, and the heat loss survey answers that.
