Air source heat pumps in West Grinstead, done properly
Air source heat pumps collect heat from outdoor air and bring it inside, using electricity to drive the process. It works on the same principle as air conditioning, run the other way, and air-to-air heat pumps are sometimes simply called air conditioning. We’re often asked to deal with comparing heat pump types and ageing boilers that will need replacing, on air-to-air heat pumps, air-to-water heat pumps and underfloor heating.
Homes around West Grinstead normally have room outside for a heat pump, so the design focuses on heat loss and radiators.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we explain those terms on your quote. Terms differ from brand to brand, and we are happy to talk you through them.

What affects the quote in West Grinstead
The quote reflects the job in front of us. We take into account:
- The distance and route between the indoor and outdoor units
- Whether it’s a simple split or a larger system
- Whether we need access equipment for high-level work
Leaving a fault or an overdue service rarely makes the work cheaper. Small problems, from blocked filters to slow leaks, tend to get worse, and a struggling system uses more electricity to do less. If you’re unsure, phone 07833 053749 or email us and we will give you an honest view and a fixed price.
Before you get in touch
To speed up the quote, send us:
- A close-up of the unit’s label showing the model number
- A photo of the consumer unit with the cover closed
- Photos showing the indoor unit and the space around it
For a fixed-price quote, ring us on 07833 053749 or email us with the address and a few details about the rooms or units involved. A few photos make it quicker. We reply to enquiries the same working day.
For landlords and property managers
Records are where property maintenance often slips. Each visit is written up, with F-Gas records wherever refrigerant work is involved, so you can show what was done and when.
Bigger systems bring extra duties: systems with an effective rated output over 12 kW need a TM44 inspection by an accredited energy assessor at least every 5 years. We arrange the inspection, get the system ready and put right anything it picks up.
Your questions about air source heat pumps in West Grinstead
Do you cover smaller places like West Grinstead?
We do. Villages and hamlets get the same service as the bigger towns. Send a few details and pictures, and we reply the same working day.
Is planning permission needed for a heat pump in West Grinstead?
It comes down to the building and the spot chosen for the outdoor unit. The half-mile around the middle of West Grinstead holds about 10 listed buildings and structures. 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 necessary, we check with the local planning authority (for West Grinstead, typically Horsham council).
Can I get a grant for an air-to-air heat pump?
Yes, but only where it becomes the home’s main heating. An air-to-air heat pump can get £2,500 if it replaces the fossil-fuel heating, meets the full heating demand, is fitted by an MCS certified installer and is in a home. Fitted alongside a boiler, it won’t qualify.
What accreditations do you have?
We’re an F-Gas certified company, with NICEIC approval for electrical work and MCS certification for heat pumps. We’re also Checkatrade members.
Is there a survey before the work?
Yes, always. Diagnosis comes before treatment: the survey shows what’s needed, where things go and what access we need and the fixed price is built on it.
Does servicing affect my warranty?
That depends on the brand. If servicing is in the terms, missing one could affect a claim, so we explain the terms on your quote.
Will you make a mess?
We put dust sheets over floors and furniture near the work first, and we tidy up as we go. Before we leave, we clear up and run through the work with you.
Homes in West Grinstead and heat pumps
About 74% of households live in detached or semi-detached houses, according to the last census (2021). Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
Sizing comes from the heat each room loses on a cold day, not from the size of the old boiler. Live in one of the older houses around Shrine Church of Our Lady of Consolation and St Francis? Expect the survey to look closely at heat loss and at the building’s planning status.
West Grinstead is about 6 miles south of Horsham, in West Sussex.

Leave it or put it right?
The two types suit different homes and needs. Air-to-water heats radiators and hot water, and can attract a £7,500 grant where eligible; air-to-air heats and cools rooms, and only qualifies for £2,500 under strict conditions. We explain which makes sense for you. Planning ahead for a job in West Grinstead means we can bring everything needed.
No two properties are the same, so each one gets its own fixed-price quote. The equipment, how we reach it, the route between units and the work needed all play a part.

How the visit works
Our engineers bring the tools, gauges and access equipment the job needs. You only need to give us clear access to the units, or their planned positions, and to the fuse board. On site, the work takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. Visits to West Grinstead are agreed with you in advance and planned so the job can be finished in one trip where possible.
- We find out about your home and the heating you have now.
- We measure heat loss for every room.
- From those figures we size the heat pump and decide on radiators, cylinder and outdoor position.
- You get a fixed price, with any grant and the VAT set out.
- Then it’s fitted, commissioned and registered with MCS.
Preparing for the visit
- Unlock any gate, garage or side passage we need
- Arrange for someone to be there to let us in
- Have the make and model of any existing unit to hand
Ask for a quote
Some jobs can be priced from photos, while others need a survey. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, you get a fixed price before any work is booked.

“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
