About our air source heat pumps in Clapham
Many air source heat pumps can be installed as permitted development in England, without a planning application. Conditions include a maximum outdoor unit size of 1.5 m³, compliance with MCS 020(a), use for more than cooling alone and a site outside the curtilage of a listed building. We look at the planning position for your home during the survey. The work covers underfloor heating, homes heated by oil, LPG or gas and air-to-water heat pumps, and the jobs we see most are working out whether radiators need upsizing and finding a place for the outdoor unit.
Older and listed homes in villages like Clapham need extra care, because permitted development doesn’t apply within the grounds of a listed building, so we check consent first.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, ready for the next service or a warranty query.

Common questions in Clapham
Will a heat pump in Clapham need planning permission?
There’s no single answer: the building and the outdoor unit position decide it. The Clapham Conservation Area takes in the middle of Clapham. 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 the planning department at Arun council, normally the authority for Clapham first.
Is Clapham within the area you cover?
Yes. Clapham is within the area we cover across London and the South East. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Will skipping a service affect the warranty?
For some brands, yes. Read the manufacturer’s terms, or send us the make and model and we’ll explain them and stick to the interval they set.
What’s the price of a heat pump installation?
For air-to-water, it’s £8,000–£16,000 (0% VAT on homes) before any Boiler Upgrade Scheme grant. Air-to-air systems are priced after a survey, with the VAT confirmed on your quote.
Can you look at a system you didn’t fit?
Yes. Systems fitted by other companies are fine from all the leading brands. Tell us the make and model and send any paperwork you have.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7 for problems that can’t wait for a planned visit. Call 07833 053749 and tell us what’s happened.
What warranty do I get?
Warranty comes from the manufacturer and depends on the brand and product. For example, Daikin’s standard warranty on split air conditioning is 2 years and we explain the terms for your brand on the quote.
What we do, step by step
Everything the job needs comes with us, from tools and test equipment to ladders and dust sheets. 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 several days for an air-to-water system with a new cylinder, less for an air-to-air system. Photos of the room and the outside of the property help us plan a visit to Clapham.
- You tell us about the home and what you want from a heat pump.
- We survey for heat loss and look at radiators, cylinder space and outdoor unit options.
- We recommend air-to-water or air-to-air and check the grant position.
- We install the heat pump and connect it up.
- We commission it, complete the MCS certificate and show you how to use it.
Getting ready for the visit
- Make sure we can reach the consumer unit or fuse board
- Unlock any gate, garage or side passage we need
- Find the manual or the paperwork for the system, if you have it

Photos are the fastest route to a quote: 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.
Advice
What you can do yourself, and what needs us
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. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Leave the units and pipework where they are. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrics need care too. If you need something moved, we can quote for it.
What a heat pump looks like in Clapham
About 68% of households live in detached or semi-detached houses, according to the 2021 Census. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
Period properties close to The Parish Church of St Mary can suit a heat pump, though insulation and any heritage protection are checked first. Historic houses such as Ecclesden Manor, about 1.5 miles south-west, are a reminder that listed homes need consent before a heat pump goes in.

- The type of system, from a single split to a larger system

- A single visit or a regular plan
Whatever the property, the quote works the same way: the equipment, the access, the work involved and the time it takes. Call for a fixed-price quote and we will explain each part.
Helping us quote
Good pictures often save a visit. The most useful are:
