Air source heat pumps for homes and businesses in Little Dunmow
Heat pumps run at lower flow temperatures than most boilers which means some radiators may need upsizing. We check each radiator against the room’s heat loss and anything that needs changing is in the quote. If you’re dealing with checking eligibility for a heat pump grant and plans to switch to electric heating with a heat pump, we can sort it out.
Older homes around Little Dunmow can be draughty or have solid walls, which a heat loss calculation will show. Sometimes insulating first makes more sense.
Aftercare is simple, and most of it is in the manual: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. That also helps where the warranty terms ask for regular servicing.

What a heat pump looks like in Little Dunmow
About 31% of homes in Little Dunmow and the neighbourhoods around it have been built since 2000, according to VOA council tax data, and about 83% of households live in detached or semi-detached houses, according to Census 2021 figures. Newer homes usually lose less heat, which tends to suit a heat pump well. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
Sizing comes from the heat each room loses on a cold day, not from the size of the old boiler. Period properties close to Church of St Mary the Virgin can suit a heat pump, though insulation and any heritage protection are checked first.

Your questions about air source heat pumps in Little Dunmow
Does the Boiler Upgrade Scheme cover homes in Little Dunmow?
Little Dunmow is in England, where the Boiler Upgrade Scheme runs. The amount depends on the type of heat pump, and the survey confirms which applies. We hold MCS certification, so the application is ours to make for you.
Do I need planning permission for a heat pump in Little Dunmow?
It depends on the property. Historic England lists about 7 buildings and structures within half a mile of the centre of Little Dunmow. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights don’t reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask the local planning authority (for Little Dunmow, typically Uttlesford council).
Can you look at a system you didn’t fit?
Yes. We look at it first and tell you what we find, including anything about the original installation that needs putting right. Any work is priced before it goes ahead.
What warranty do I get?
It’s the manufacturer’s warranty, which varies by brand. For instance, Daikin’s standard warranty on split air conditioning is 2 years and we explain the terms for your brand on the quote.
What does an air-to-water heat pump cost?
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.
Will I get records for the system?
Yes. It’s your proof of what was done: a dated note of the work, with refrigerant details where they apply.
Do you work in Little Dunmow?
Yes. Little Dunmow is part of the area we cover, within the South East and London area we cover. We’re based in East Grinstead, West Sussex.
What affects the quote in Little Dunmow
Before we fix a price, we need to know a few things. We check:
- Whether it’s a simple split or a larger system
- A single visit or a regular plan
- Which make and model is being fitted or worked on
Putting the work off seldom saves money. Small problems, from blocked filters to slow leaks, tend to get worse, and a struggling system uses more electricity to do less. If you are not sure what’s needed, phone 07833 053749 or drop us a line for straight advice and a fixed price.
What we need to know
A few details help us quote accurately. With your enquiry, please include:
- The postcode and whether it’s a home, flat or business
- Any previous service or F-Gas records
- A short video of any fault, such as a noise or a flashing light
Published ranges are a starting point; the quote is built on your property, because every property is different. Once we have looked at the job, from pictures or on a survey, you get a fixed price. To get going, ring us on 07833 053749 or email us.
What you can do yourself, and what needs us
Good habits make our visits easier, not unnecessary. Simple care keeps the air moving through the system, but the refrigerant circuit, the electrics and the parts you can’t see still need an engineer at the interval the manufacturer recommends.
On air conditioning, the filters in the indoor unit are typically the one part owners can clean where the manufacturer’s manual explains how. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
How the visit works
The visit goes in the diary at a time that works for you, and we let you know if plans need to move. On arrival, the engineer compares the job with the survey, your pictures or the details you gave us. Anything unexpected is raised with you before we go further. From there, the work takes a few days on site, depending on the cylinder, the radiators and the pipework involved. Everything the job in Little Dunmow needs is worked out beforehand.
- We find out about your home and the heating you have now.
- Every room’s heat loss is worked out on site.
- From those figures we size the heat pump and decide on radiators, cylinder and outdoor position.
- You get a fixed price, with any grant and the VAT set out.
- Installation, commissioning and MCS registration complete the job.
How to prepare
- Keep pets out of the rooms we are working in
- Make sure we can reach the consumer unit or fuse board
- Give us access to the outside wall, roof or yard where the outdoor unit sits
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, the quote is fixed before anything goes ahead.

“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
