Heat pumps in Cranleigh: local notes
About 70% of households live in detached or semi-detached houses, according to the 2021 Census. Houses typically have space for an outdoor unit and a hot water cylinder.
Period properties close to Church of St Nicholas can suit a heat pump, though insulation and any heritage protection are checked first. Every heat pump design starts with a room-by-room heat loss calculation.

Air source heat pumps for homes and businesses in Cranleigh
A heat pump takes heat from the outside air and moves it into your home with electricity running the compressor and fans. 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. The work covers underfloor heating, air-to-air heat pumps and air-to-water heat pumps, and people most often call us about checking whether planning permission is needed and ageing boilers that will need replacing.
If your home near Cranleigh has no mains gas, the grant can be bigger. Homes heated by oil or LPG with no mains gas can get an extra £1,500 on the Boiler Upgrade Scheme until March 2027, for an air source or ground source heat pump.
Nothing is signed off by word of mouth: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. File it with the manual, because it helps with any later warranty question.

- Gas boiler work, such as disconnecting the old boiler, which needs a Gas Safe registered engineer
- Improving the building’s insulation
- Promising eligibility for the Boiler Upgrade Scheme

What we do, step by step
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. Everything the job in Cranleigh needs is worked out beforehand.
- We find out about your home and the heating you have now.
- Every room’s heat loss is worked out on site.
- The design covers the heat pump, emitters, hot water and outdoor unit.
- Cost, grant and VAT appear on one fixed-price quote.
- Then it’s fitted, commissioned and registered with MCS.
How to prepare
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Move furniture away from the wall where we will be working
- Arrange for someone to be there to let us in
Getting a quote
Quoting starts with a diagnosis, from a site survey or, where the job is straightforward, from photos and measurements. Then you get a fixed price before any work starts.
Related advice
Keeping the system healthy
So the system stays in good health:
- Keep to regular servicing
- Leave indoor units unobstructed
- Use the settings explained at handover
In cold, damp weather the outdoor unit runs a defrost cycle from time to time. You might see steam or hear the unit change note, and that’s normal.
Have the system serviced regularly. Check the manufacturer’s terms, as they may include servicing conditions.
Questions from Cranleigh
Do you cover smaller places like Cranleigh?
Yes, smaller places are covered as well as towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
Is a heat pump in Cranleigh permitted development?
It depends on the property. The Cranleigh Conservation Area is close to the centre of Cranleigh. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights don’t reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask the planning department at Waverley council, usually the authority for Cranleigh.
What VAT do I pay on a heat pump?
Under HMRC Notice 708/6, a heat pump installed in a home is zero-rated until 31 March 2027, then 5%. With air-to-air, HMRC’s view depends on the product, so we confirm the VAT on the quote.
Do you survey before quoting?
Yes. We always look before we price, either on a site survey or from photos and details for simple jobs. A fixed-price quote follows.
Which type of heat pump is right for my home?
Air-to-water feeds your central heating and hot water, while air-to-air warms and cools rooms directly. Air-to-air doesn’t heat hot water, and we explain which suits your home.
Can I do any of the installation myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That is a legal requirement, and manufacturers expect it for their warranty too. We can quote for the whole job, from supply to commissioning.
What accreditations do you have?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
What affects the cost of air source heat pumps
You’ll get a fixed price before work begins. It takes into account:
- The size of the job
- The type of system, from a single split to a larger system
- A single visit or a regular plan
What you pay reflects the actual work. That’s why we look at the job first, from pictures or on a survey, and why the quote is fixed before we start.
What we need to know
When you call or email, it’s useful to have:
- A photo of the consumer unit with the cover closed
- The outdoor side of the property, including any roof or flat area
- Any error code or flashing light on the display
Photos are enough for some jobs; others need a visit first. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, the quote is fixed before anything goes ahead.
What a customer said
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
