Air source heat pumps in Horndean, done properly
Heat pumps run at lower flow temperatures than most boilers which means some radiators may need upsizing. The survey shows which rooms are fine and which need changes, and the quote sets it out. The work covers hot water cylinders, homes heated by oil, LPG or gas and radiator systems, and common reasons people get in touch are a boiler that’s getting old and choosing between air-to-water and air-to-air.
Most homes around Horndean have space for the outdoor unit, and the position has to pass the MCS planning standard’s noise check to count as permitted development.
We’re an F-Gas certified company, NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

Leave it or put it right?
Replacing a boiler in a hurry when it breaks leaves little time to consider a heat pump. Planning ahead gives time for the heat loss survey, the design and the grant application while the old heating still works. Booking in spring means a home in Horndean is ready for summer.

What we do, step by step
Our engineers arrive at the time agreed with you and check the plan with you first. Dust sheets go down over floors and anything close to the work, and anything electrical is made safe before work starts. On site, it takes a few days for most air-to-water installations, with air-to-air systems often quicker. Shops and offices in Horndean can usually stay open while we work, or we come after hours.
- First we talk through the property and the current system.
- Every room’s heat loss is worked out on site.
- The design covers the heat pump, emitters, hot water and outdoor unit.
- You get a fixed price, with any grant and the VAT set out.
- We install, commission and register the system under MCS.
How to prepare
- Clear the space around the indoor unit, or where it will go
- Let us know if the units are on a roof, a high wall or in a locked area
- Make sure someone can let us in at the agreed time
How to get a quote
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, you get a fixed price before any work is booked.

FAQs for Horndean
Is Horndean in your area for air source heat pumps?
We do: Horndean falls inside our working area. To start, phone 07833 053749 or email us with a few pictures.
Is the heat pump grant available in Horndean?
Yes, if the home and the heat pump meet the scheme’s rules: Horndean is in England, where it applies. The grant is £7,500 for an air source (air-to-water) heat pump and £2,500 for an air-to-air system that replaces the existing fossil-fuel heating. The installer applies, and we are MCS certified.
Is there a survey before the work?
Yes. Photos often do the job for simple work, while larger systems and faults that need testing are seen on site.
What accreditations do you have?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, plus Checkatrade membership. Engineers who handle refrigerant hold their own F-gas qualifications as well.
Can I do any of the installation myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That’s the law, not just our preference, and it also matters for the manufacturer’s warranty. We can quote for the whole job, from supply to commissioning.
Are my radiators big enough 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.
Can you come out in an emergency?
Yes. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we will agree what happens next.
Let and managed properties
The F-gas rules share responsibility for leak checking between the equipment’s operator and the service technicians. In a let or managed building, it’s worth agreeing who that operator is and we’re happy to deal with whoever it is.
We regularly work with managing agents. Send the address, what’s needed and how access works and we will come back with a fixed-price quote.
