Managing agents and facilities teams in Farnham
Under the GB F-gas rules, responsibility for leak checks is shared between whoever operates the equipment and the engineers who work on it. In a let or managed building, it’s worth agreeing who that operator is, and we can work for either side.
Whether it’s one property or many, the approach is the same: diagnosis, a fixed price, access agreed with the people on site and paperwork at the end.
About our air source heat pumps in Farnham
Until 31 March 2027, a heat pump installed in residential accommodation carries 0% VAT, with 5% from 1 April 2027. That follows HMRC Notice 708/6, and it doesn’t apply to businesses. For air-to-air systems, we confirm the VAT on your quote. Please treat this as general information rather than tax advice. If you are dealing with moving away from fossil-fuel heating and comparing heat pump types, we can help.
If your home in or near Farnham is heated by oil, LPG or electric heaters with no mains gas, the Boiler Upgrade Scheme adds an extra £1,500 until March 2027 for an air source or ground source heat pump.
Equipment warranty comes from the manufacturer, on its own terms, and we explain those terms on your quote. Terms differ from brand to brand, so we go through them with you rather than leave you to find the small print.

Heat pumps in Farnham: local notes
Valuation Office Agency council tax records show about 30% of homes in Farnham and the neighbourhoods around it were built in 2000 or later. Lower heat loss in recent homes often means a smaller heat pump and fewer radiator changes.
Older homes near Church of St Mary the Virgin may need extra checks for planning and heat loss before a heat pump is designed.

Owner checks or an engineer?
Keep a note of anything odd: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It helps us diagnose quickly, and a photo or a short video of the display is even better.
There are a few things you can safely do yourself: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Opening up the units, the electrics and the refrigerant circuit are a job for us.
Your questions about air source heat pumps in Farnham
Is a heat pump in Farnham permitted development?
It comes down to the building and the spot chosen for the outdoor unit. Historic England lists about 18 buildings and structures within half a mile of the centre of Farnham. Heat pumps on houses are often permitted development, but listed buildings need consent and conservation areas restrict outdoor units facing a road. Where it’s needed, we check with the planning department at Uttlesford council, typically the authority for Farnham.
Is the heat pump grant available in Farnham?
Farnham is covered, as the scheme runs across England and Wales. Air-to-water and ground source systems attract £7,500. Air-to-air gets £2,500, but only where it takes over from fossil-fuel heating and covers the whole home’s heating demand. The installer applies, and we’re MCS certified.
How long does a heat pump installation take?
Expect it to take several days for an air-to-water system with a new cylinder, less for an air-to-air system. How much of the heating changes decides most of the time and the timing is set out with your quote.
When will I hear back?
We reply to enquiries the same working day. If it’s an emergency, ring the 24/7 line instead.
Do you work for landlords and businesses?
Yes. Homeowners, landlords, agents and businesses all book us across London and the South East. Let us know who the records should go to.
Are you F-Gas certified?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, and we are Checkatrade members. Engineers who handle refrigerant hold their own F-gas qualifications as well.
Do I need new radiators for a heat pump?
The heat loss survey answers that, room by room. Where a radiator is already large enough, it stays, and any that need upsizing are set out in the quote.
How it works
Our engineers bring the tools, gauges and access equipment the job needs. All we ask is clear access to the units, or to where they’ll go, and to the consumer unit. On site, the work takes anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes. We agree a date with you and plan the visit to Farnham so we arrive with what’s needed.
- It begins with your house and the heating it relies on now.
- We measure heat loss for every room.
- 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.
Getting ready for the visit
- Tell us about any building rules, permits or sign-in
- Tell us about parking and loading
- Tell us about access, such as roof hatches, high walls or locked plant areas
Get a fixed-price quote
The quickest way to a quote is to send pictures: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Add the address and what you’d like done, and many jobs can be priced from that.
Related advice
Do you need air source heat pumps in Farnham?
Air-to-air systems interest people who want cooling in summer as well as heating. They heat rooms through wall, floor or ceiling units and switch to cooling in warm weather. The grant only applies in some cases, so we check first.
These are the situations we see most often:
- Working out where a cylinder could go
- Moving away from fossil-fuel heating
- Radiators that may be too small for a heat pump
Much Hadham Palace lies about 4.2 miles south-west. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions.
What to look for in a quote
- If the quote is based on a survey, photos or a diagnosis
- Proof of F-Gas company certification
- Whether testing, commissioning and paperwork are included
