About our air source heat pumps in Simpson
In England, an air source heat pump on a house can often go in under permitted development rights. 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 check the rules for your property as part of the survey. Common call-outs are for not knowing whether a grant applies and planning and permitted development questions, across hot water cylinders, air-to-air heat pumps and air-to-water heat pumps.
In a place like Simpson, some homes are listed, and permitted development doesn’t cover listed buildings, so consent comes first.
Each manufacturer sets its own warranty period. Daikin, for example, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. Whatever the brand, the manufacturer’s terms are explained on your quote.

How it works
Our engineers arrive at the time agreed with you and check the plan with you first. Dust sheets go down over floors and anything close to the work, and anything electrical is made safe before work starts. The work itself takes from a couple of days to around a week, depending on the system and how much of the heating changes. Photos of the room and the outside of the property help us plan a visit to Simpson.
- You tell us about the home and what you want from a heat pump.
- The survey checks heat loss, emitters, hot water and the outdoor unit position.
- We explain which type of heat pump suits the home and whether a grant could apply.
- Installation follows on the agreed dates.
- After commissioning, you get the MCS certificate and a handover.
Before we arrive
- Plan for pets to be kept clear during the visit
- Mention any roof access, ladders or high-level work
- Arrange for someone to be there to let us in

FAQs for Simpson
Do you cover smaller places like Simpson?
Yes. Simpson is within the area we cover across London and the South East. A few photos and the postcode are enough to get things started.
Is planning permission needed for a heat pump in Simpson?
There’s no single answer: the building and the outdoor unit position decide it. The half-mile around the middle of Simpson holds about 14 listed buildings and structures. 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 Milton Keynes council, which is typically the planning authority for Simpson first.
Is the equipment covered by a warranty?
The manufacturer’s warranty, on the manufacturer’s terms. Each brand sets its own conditions and periods, so we explain them on your quote.
Which type of heat pump is right for my home?
Air-to-water feeds your central heating and hot water, while air-to-air warms and cools rooms directly. Air-to-air doesn’t heat hot water, and we explain which suits your home.
Will you make a mess?
Floors and furniture near the work are covered with dust sheets before we start, and the area is kept tidy throughout. Before we leave, we clear up and run through the work with you.
Which accreditations do you hold?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, and we are Checkatrade members. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
Are my radiators big enough for a heat pump?
That depends on the room’s heat loss and the radiator’s size. The survey compares each radiator with the room’s needs, so the quote covers any changes.
Air source heat pumps in Simpson: the local picture
VOA council tax data show about 32% of homes across Simpson and its surrounding area were built in 2000 or later, and the 2021 Census found about 37% of households in terraced houses. Better insulated, newer homes are often a good match for a heat pump. Shared walls keep a terrace’s heat loss down, while gardens next door make the noise check on the outdoor unit important.
Bletchley Park lies about 1.7 miles south-west. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions. Older homes near Church of St Thomas may need extra checks for planning and heat loss before a heat pump is designed.

Aftercare tips
Systems last better with the right care. We suggest:
- Clear leaves and debris from the outdoor unit
- Keep the MCS certificate with the manufacturer’s paperwork
- Use the settings explained at handover
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.

Landlords, agents and facilities managers
When the building owner and the occupier are different, the lease or tenancy agreement normally sets out who maintains what. We can quote either party, and the paperwork can go to both.
We work for landlords, letting agents and managing agents as well as homeowners and businesses. Let us know who will give us access and who the records should go to and we will copy in whoever needs it.

“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.”
