Air source heat pumps around Aspley Guise
About 65% of homes in Aspley Guise and the neighbourhoods around it have been built since 2000, according to Valuation Office Agency council tax records, and about 69% of households live in detached or semi-detached houses, according to the 2021 Census. Lower heat loss in recent homes often means a smaller heat pump and fewer radiator changes. Houses typically have space for an outdoor unit and a hot water cylinder. The middle of Aspley Guise is part of the Aspley Guise Conservation Area. Draw a one-mile circle round the middle of Aspley Guise and it takes in 3 conservation areas. Listed buildings are part of the picture here: about 30 within half a mile of the centre, such as Guise House (grade II*). So the heat pump survey asks two extra questions here: is the home listed, and is it inside a conservation area?
Woburn Abbey, roughly 2.5 miles south-east, is a reminder to check your home’s listing status: permitted development does not cover listed buildings. If your home is near Aspley Guise station and heated by a gas boiler, an air-to-water heat pump can replace it where the survey shows it suits.

How we handle air source heat pumps in Aspley Guise
As an MCS certified installer, we fit air source heat pumps for homes in Aspley Guise and the rest of Milton Keynes. Air-to-water systems feed your radiators or underfloor heating and hot water cylinder, while air-to-air systems heat rooms directly through indoor units and can cool them too. We help you work out which suits your home. The work covers air-to-water heat pumps, underfloor heating and radiator systems, and people most often call us about plans to switch to electric heating with a heat pump and working out whether radiators need upsizing.
Homes around Aspley Guise typically have room outside for a heat pump, so the design comes down to heat loss, radiators and hot water.
Whatever the visit, you get a written record: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. Keep it with the system’s paperwork so it’s to hand next time.

Keeping the system healthy
Once we have finished, these simple steps help:
- Check what your manufacturer’s warranty asks of you
- Avoid switching the heat pump on and off often
- Keep the MCS certificate with the manufacturer’s paperwork
If you were eligible for a grant, we handle the application and keep you updated, as the installer applies for it.
A well-insulated home helps a heat pump, as lower heat loss means the system has less to do.
What happens if it’s left?
Permitted development rules can change, and conditions vary between properties. We look at the planning position early, so there are no surprises covering listed buildings, conservation areas and any Article 4 direction. Small faults tend to grow, so it’s worth dealing with them early.
Leaving a fault or an overdue service rarely makes the work cheaper. 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, call us on 07833 053749 or fill in the contact form for straight advice and a fixed price.

Aspley Guise: your questions answered
Does the Boiler Upgrade Scheme cover homes in Aspley Guise?
Yes, if the home and the heat pump meet the scheme’s rules: Aspley Guise is in England, where it applies. It gives £7,500 towards an air-to-water or ground source heat pump, or £2,500 towards an air-to-air heat pump that replaces the fossil-fuel heating and meets the whole home’s heating need. We hold MCS certification, so the application is ours to make for you.
Do you cover smaller places like Aspley Guise?
We do. Villages and hamlets get the same service as the bigger towns. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Do you work for landlords and businesses?
Yes. Homeowners, landlords, agents and businesses all book us in Aspley Guise and across Milton Keynes. Let us know who the records should go to.
Do you provide F-Gas records?
Yes, on every job. New installations come with commissioning details, F-Gas records and warranty information, while repairs and services get a written note of what was found and done.
Do you look at the job first?
Yes, every time. We diagnose before we treat: the survey tells us what the job needs and how to do it, and the quote is based on that.
Do you have a 24/7 line?
Yes, any time. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we’ll tell you what to do first.
Do you offer maintenance contracts?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Each visit is written up and F-Gas records kept where they apply.
What happens on the day
Protection comes first: sheets over the floor and any furniture nearby, and we ask before moving anything. Then the electrics are made safe and the work begins. It takes from a couple of days to around a week, depending on the system and how much of the heating changes, and we tidy up before we leave. Photos of the existing unit help with repairs and servicing in Aspley Guise.
- We start with your plans and the property.
- The survey checks heat loss, emitters, hot water and the outdoor unit position.
- You get our view on the right type for the house, and on whether the Boiler Upgrade Scheme applies.
- The system is installed and connected to the controls.
- The job ends with commissioning, the MCS certificate and a walk through the controls.
Getting ready for the visit
- Let us know where the consumer unit is
- Keep pets and children away from the work area
- Arrange for someone to be there to let us in

Our prices page gives typical ranges, but your quote is based on your job, because every property is different. After a look at the job, by photos or a survey, the price is fixed. To get going, give us a ring on 07833 053749, or email if that’s easier.
Advice
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 cannot see still need an engineer at the interval the manufacturer recommends.
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 electrical side needs a competent person. If you need something moved, we can quote for it.
