How the job changes from property to property
The Boiler Upgrade Scheme
Not every home qualifies and we confirm it before anything is agreed.
Outdoor unit position and planning
Flats have tighter limits, and an Article 4 direction can remove permitted development rights. Listed building consent is a separate matter, and we check the position for your property.
How we handle air source heat pumps in Caterham
For an air-to-water heat pump, the price is £8,000–£16,000 (0% VAT on homes), before the grant. In England and Wales, the Boiler Upgrade Scheme offers a £7,500 grant towards an eligible air-to-water installation, and as the installer we apply for it on your behalf. Not every home qualifies, so we check eligibility before you commit. The work covers air-to-air heat pumps, radiator systems and homes heated by oil, LPG or gas, and the jobs we see most are no space for a hot water cylinder and radiators that may be too small for a heat pump.
Around Caterham, most people asking about heat pumps have a gas boiler now. A survey looks at heat loss, radiators, the hot water cylinder and where the outdoor unit can go, then design the system.
Refrigerant work is written up in the F-Gas records: the work carried out, the refrigerant involved and the quantities. File them with the system’s paperwork, ready for the next service or a warranty query.

The process
Everything the job needs comes with us, from tools and test equipment to ladders and dust sheets. 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 a few days for most air-to-water installations, with air-to-air systems often quicker. Photos of the room and the outside wall help us plan a job in Caterham.
- First we find out about the property, the heating you have now and what you’re hoping for.
- The survey measures heat loss room by room and looks at radiators, hot water and the best spot for the outdoor unit.
- You get a fixed-price quote, with any grant you are eligible for and the VAT explained.
- The outdoor unit, the indoor equipment and the controls are installed and connected.
- The system is commissioned and registered under MCS, and we show you how to use it.
Preparing for the visit
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Arrange for someone to be there to let us in

What owners can safely do
Refrigerant is off limits for anyone without the right qualifications. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and refrigerant lines can cause cold burns. If you suspect a leak, switch the system off and call us.
Good habits make our visits easier, not unnecessary. Clean filters and a clear outdoor unit help the system run as it should, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.
Fixed-price quotes for air source heat pumps in Caterham
The quote reflects the job in front of us. We consider:
- What state the existing equipment is in
- Whether the existing supply is suitable
- The brand, model and parts involved
A single unit or a whole estate, we price it on the same basis: the work involved, the access and the equipment. The price is fixed before work begins, and the quote sets out the VAT.
Asking for a quote
Photos let us diagnose from a distance. The most useful are:
- The paperwork from the last service, if you have it
- The outdoor side of the property, including any roof or flat area
- Where the property is and what kind of building it is
Every quote shows the VAT clearly, with the rate that applies to your job. VAT can differ between homes and businesses and between kinds of work, so we confirm it in writing rather than guess. To get one, phone us on 07833 053749 or drop us a line.
FAQs for Caterham
Does the Boiler Upgrade Scheme cover homes in Caterham?
Yes, the scheme covers homes in England, including Caterham, if they qualify. It gives £7,500 towards an air-to-water or ground source heat pump, or £2,500 towards an air-to-air heat pump that replaces the fossil-fuel heating and meets the whole home’s heating need. The installer applies, and we are MCS certified.
Can I fit a heat pump in Caterham without planning permission?
The answer turns on the property and where the outdoor unit would sit. The half-mile around the middle of Caterham holds about 11 listed buildings and structures. 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 Tandridge council, which is usually the planning authority for Caterham.
Will skipping a service affect the warranty?
Each manufacturer decides. If servicing is in the terms, missing one could affect a claim and we’ll tell you what your brand asks for.
Whose job is it to check the system for leaks?
Whoever operates the equipment, together with the technicians who service it. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We will work out which band applies to yours.
What accreditations do you have?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, plus Checkatrade membership. Engineers who handle refrigerant hold their own F-gas qualifications as well.
Which type of heat pump is right for my home?
It depends on your home, your heating and whether you want cooling. Air-to-water can attract a £7,500 grant where eligible; air-to-air only qualifies for £2,500 under strict conditions. We explain the options after the survey.
Are my radiators big enough for a heat pump?
The heat loss survey answers that, room by room. Rooms where the radiator is big enough stay as they are, and any that need upsizing are set out in the quote.
