About our air source heat pumps in Downham
We install air source heat pumps in Downham and across Essex, and we are MCS certified. There are two kinds: air-to-water, which heats radiators or underfloor heating and your hot water, and air-to-air, which warms rooms through indoor units and can also cool. We help you work out which suits your home. The work covers air-to-water heat pumps, homes heated by oil, LPG or gas and radiator systems, and people most often call us about checking whether planning permission is needed and an oil, LPG or gas boiler near the end of its life.
Homes around Downham typically have room outside for a heat pump, so the design focuses on heat loss and radiators.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. If that applies to your system, booking the service on time keeps the record straight, and every service is written up.

What air source heat pumps cannot fix
An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:
- Getting planning permission or listed building consent on your behalf
- Improving the building’s insulation
- Promising eligibility for the Boiler Upgrade Scheme
If you are not sure, just call us on 07833 053749 or send an email and we will give you a straight answer before you book.
Parts of the system we cover
- Air-to-water heat pumps
- Hot water cylinders
- Underfloor heating
- Radiator systems
- Homes heated by oil, LPG or gas
- Air-to-air heat pumps
Why deal with it now?
Radiators that are too small for a heat pump’s lower flow temperature leave rooms cool. Checking and upsizing them as part of the installation avoids that. For a village like Downham, booking ahead lets us plan the trip properly.
What you pay reflects the actual work. That’s why every job is looked at first, and the price is agreed before we start.

Air source heat pumps in Downham: the local picture
About 37% of homes in Downham and the neighbourhoods around it have been built since 2000, according to VOA council tax data, and about 79% of households live in detached or semi-detached houses, according to the 2021 Census. Better insulated, newer homes are often a good match for a heat pump. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
If your home is listed, like Ingatestone Hall about 4.7 miles west, listed building consent comes before any heat pump work. Older homes near Church of St Margaret may need extra checks for planning and heat loss before a heat pump is designed.

What we do, step by step
The first job on site is protection: dust sheets over floors and furniture near the work, and we ask before moving anything. Then the electrics are made safe and the work begins. It takes a few days for most air-to-water installations, with air-to-air systems often quicker, and we tidy up before we leave. Pictures of the space and where the outdoor unit could go let us plan the work in Downham.
- We start with your plans and the property.
- We survey for heat loss and look at radiators, cylinder space and outdoor unit options.
- You get our view on the right type for the house, and on whether the Boiler Upgrade Scheme applies.
- We install the heat pump and connect it up.
- The job ends with commissioning, the MCS certificate and a walk through the controls.
Getting ready for the visit
- Tell us about any building rules, permits or sign-in
- Let us know if the units are on a roof, a high wall or in a locked area
- Make sure we can reach the outdoor unit, or where it will go

After we’ve gone
Simple habits make a real difference. Our advice:
- File the MCS certificate safely
- Check eligibility for the Boiler Upgrade Scheme early
- Diary the next service
The warranty on the heat pump is the manufacturer’s, on its own terms. We go through the conditions with you, including any servicing they ask for.
Keep radiators and indoor units unobstructed, as the system relies on them giving out heat.
Your questions about air source heat pumps in Downham
Does the Boiler Upgrade Scheme cover homes in Downham?
Yes, if the home and the heat pump meet the scheme’s rules: Downham is in England, where it applies. For an air-to-water heat pump the amount is £7,500; an air-to-air system can get £2,500 if it replaces the fossil-fuel heating outright, meets the home’s full heating demand and is not an add-on to a boiler. The installer applies, and we’re MCS certified.
Can I fit a heat pump in Downham without planning permission?
That depends on the building and where the outdoor unit goes. Around 4 listed entries sit within 0.5 miles of central Downham. The permitted development rules for heat pumps leave out listed buildings and stop outdoor units going on road-facing walls or roofs in conservation areas. Anything outside the rules needs an application, and we raise it with Chelmsford council, which is usually the planning authority for Downham first.
Which accreditations do you hold?
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.
Does servicing affect my 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.
Can I fit air conditioning or a heat pump myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That is a legal requirement, and it also matters for the manufacturer’s warranty. We’re happy to quote for the full job, supply to commissioning.
What does an air-to-water heat pump cost?
Expect £8,000–£16,000 for an air-to-water system, with 0% VAT on homes, before the grant is taken off. Where you land depends on the size of heat pump, any radiators that need changing and the hot water cylinder. Air-to-air is priced after a survey.
Do you cover Downham?
Yes. Downham is part of the area we cover, within the South East and London area we cover. Our base is in East Grinstead, West Sussex.
