About our air source heat pumps in Bletchley
A £2,500 grant is available for some air-to-air heat pumps, with conditions. The system must replace the existing fossil-fuel heating and meet the home’s full heating demand, it must be installed by an MCS certified installer, and it must be in a home; adding it alongside a boiler doesn’t qualify. Common call-outs are for finding a place for the outdoor unit and not knowing whether a grant applies, across homes heated by oil, LPG or gas, underfloor heating and hot water cylinders.
Houses in Bletchley usually have room for an outdoor unit at the side or rear, and the position has to pass the MCS planning standard’s noise check to count as permitted development.
Looking after a system is mostly common sense: 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.

The process
Each visit runs to the same pattern: agree the plan on site, protect the area, carry out the job, test what we’ve done and explain it all to you. The visit itself takes from a couple of days to around a week, depending on the system and how much of the heating changes. In a town like Bletchley, parking is normally straightforward, so the main questions are access and timing.
- We find out about your home and the heating you have now.
- A heat loss survey is carried out, room by room.
- We design the system, check the radiators and cylinder and look at the outdoor unit position.
- You get a fixed price, with any grant and the VAT set out.
- Installation, commissioning and MCS registration complete the job.
Before we arrive
- Clear access to the fuse board
- 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
Getting a price
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. Tell us the address and what you need, and many jobs can be priced from that.

About 63% of households live in detached or semi-detached houses, according to Census 2021 figures. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.

Fixed-price quotes for air source heat pumps in Bletchley
Some jobs are bigger than they look, and some smaller. The main factors:
- The distance and route between the indoor and outdoor units
- The condition of any existing system
- The equipment or parts the job needs
Leaving a fault or an overdue service rarely makes the work cheaper. Faults and wear in a system tend to grow, and a system working harder than it should costs more to run. If you’re unsure, give us a ring on 07833 053749 or use the quote form for straight advice and a fixed price.
Asking for a quote
To speed up the quote, please include:
- Your installation or service records
- Your consumer unit or fuse board
- Where the outdoor unit is, or where you’d like it
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 start, ring 07833 053749 or drop us a line.
Keeping the system healthy
Here’s the after-treatment advice, in brief:
- Check what your manufacturer’s warranty asks of you
- Keep the outdoor unit clear all year
- Keep to regular servicing
Once commissioned, we register the installation with MCS and give you the certificate. Keep it with the manufacturer’s paperwork, as you may need it later.
Keep insulation and draught-proofing in good order because it reduces the heat the system needs to supply.
Bletchley questions
Is Bletchley in your area for air source heat pumps?
Yes. We work across London and the South East from our base in East Grinstead, and Bletchley is part of that. Get in touch with the details and we reply the same working day.
Is planning permission needed for a heat pump in Bletchley?
It depends on the property. There’s a conservation area, the Bletchley Conservation Area, close to central Bletchley. 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 Bletchley first.
Can you look at a system you didn’t fit?
Yes. We work on systems fitted by other installers as well as our own from all the leading brands. Send us the make and model, and any records you have.
Does the grant cover air-to-air heat pumps?
It can, as long as the system takes over the heating completely. An air-to-air heat pump can get £2,500 if it replaces the fossil-fuel heating, meets the full heating demand, is fitted by an MCS certified installer and is in a home; as an add-on to a boiler it doesn’t qualify.
Will my radiators work with a heat pump?
The heat loss survey answers that, room by room. Rooms where the radiator is big enough stay as they are and any changes are in the quote.
Will you make a mess?
Floors and furniture near the work are covered with dust sheets before we start, and we tidy up as we go. Before we leave, we clear up and run through the work with you.
Do I need to service the system to keep the warranty?
It can, for some brands. Send us the make and model and we’ll tell you what the manufacturer expects, and book the service at the interval they recommend.
Managing agents and facilities teams in Bletchley
Facilities teams in offices, schools and public buildings book us too in Bletchley and across Milton Keynes. Work can be phased by floor, zone or building around the people who use them.
Larger air conditioning systems in buildings need more than servicing: a TM44 inspection by an accredited energy assessor is required at least every 5 years for systems over 12 kW. We arrange the inspection, get the system ready and put right anything it picks up.
What a customer said
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
