Air source heat pumps in Westhumble, done properly
A £2,500 grant is available for some air-to-air heat pumps, with conditions. It has to replace the fossil-fuel heating, cover the whole heating demand, be fitted by an MCS certified installer and be in a home; adding it alongside a boiler does not qualify. Common call-outs are for questions about where the outdoor unit can go and checking eligibility for a heat pump grant, on air-to-water heat pumps, homes heated by oil, LPG or gas and hot water cylinders.
Space for an outdoor unit is rarely an issue near Westhumble, so the design focuses on heat loss and radiators.
The records are your system’s health record: what was fitted or found, what was done and when. It makes the next visit quicker and any warranty question simpler, so keep it safe.

Westhumble questions
Is Westhumble within the area you cover?
Yes. Westhumble is within the area we cover across London and the South East. A few pictures and the postcode are enough to get things started.
Is the heat pump grant available in Westhumble?
Yes, the scheme covers homes in England, including Westhumble, if they qualify. 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. We hold MCS certification, so the application is ours to make for you.
Do I need planning permission for a heat pump?
It depends on the property and where the unit goes. Flats have different limits, conservation areas have extra conditions, and an Article 4 direction can remove the rights and we look at it during the survey.
Which brands do you work with?
We work with the leading brands, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we will take it from there.
Can we book visits on a schedule?
Yes. We offer maintenance contracts, with visits at the interval your system and the manufacturer need. Every visit is recorded, with F-Gas records where refrigerant work is involved.
Do you work on systems someone else installed?
Yes. Systems fitted by other companies are fine from all the leading brands. Send us the make and model, and any records you have.
Do you provide F-Gas records?
Yes, always. New installations come with commissioning details, F-Gas records and warranty information, and repairs and services get a record of the work.
When to call us in Westhumble
When a home is being extended or renovated, it’s a good moment to look at heat pumps. It’s simpler to plan radiators, pipework and a cylinder while the builders are in.
Look out for any of the following:
- Checking whether planning permission is needed
- No space for a hot water cylinder
- Choosing between air-to-water and air-to-air
Older homes near Church of St Michael may need extra checks for planning and heat loss before a heat pump is designed.
What your quote should include
- Whether the price is fixed or an estimate
- What paperwork you’ll receive afterwards
- Which brand and model they’re proposing, and why
How it works
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 a few days for most air-to-water installations, with air-to-air systems often quicker. For a place like Westhumble, the timing is set with you and the travel is our side of the planning.
- First we find out about the property, the heating you have now and what you’re hoping for.
- We survey the home room by room for heat loss, and check the emitters, hot water and outdoor unit position.
- We send a fixed-price quote that shows the equipment, the grant position and the VAT.
- We fit the outdoor unit and connect it to the heating, hot water and controls.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
Before we arrive
- Clear the space around the indoor unit, or where it will go
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Tell us about any building rules, permits or sign-in

About 10 listed entries lie within half a mile of central Westhumble, Lovedon Cottage (grade II) among them.
