How we price air source heat pumps
Your quote is based on your property. We take into account:
- One-off work versus a regular service cycle
- Which make and model is being fitted or worked on
- Whether it’s a simple split or a larger system
One room or a whole building, the quote is built the same way: the work involved, the access and the equipment. The price is fixed before we start, with VAT shown clearly.
What to send for a quote
Photos let us diagnose from a distance. The most useful are:
- The make and model of the system, from the label
- Your installation or service records
- A few pictures of the room and the wall the unit is on, or will go on
Photos are the fastest route to a quote: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Tell us the address and what you need, and simple jobs can often be priced without a visit.
About our air source heat pumps in Harwell
Heat pumps run at lower flow temperatures than most boilers, so radiators may need to be larger to give out the same heat. The survey shows which rooms are fine and which need changes and anything that needs changing is in the quote. We are often asked to deal with finding a place for the outdoor unit and wanting to stop using oil, LPG or gas for heating, on air-to-water heat pumps, hot water cylinders and homes heated by oil, LPG or gas.
If your home near Harwell has no mains gas, the grant can be bigger. Until March 2027, homes on oil or LPG without mains gas can get an extra £1,500 through the Boiler Upgrade Scheme.
Nothing is signed off by word of mouth: 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. File it with the manual so it’s to hand next time.

Safe owner checks
Never try to top up, release or handle refrigerant yourself. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and escaping refrigerant can cause cold burns. A suspected leak is our job, not yours.
There are a few things you can safely do yourself: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Anything inside the units, the electrics and the refrigerant is engineer’s work.

Your questions about air source heat pumps in Harwell
Is the heat pump grant available in Harwell?
Harwell is in England, where the Boiler Upgrade Scheme runs. For an air-to-water heat pump the amount is £7,500; an air-to-air system can get £2,500 if it replaces the fossil-fuel heating outright, meets the home’s full heating demand and is not an add-on to a boiler. We hold MCS certification, so the application is ours to make for you.
Is a heat pump in Harwell permitted development?
There’s no single answer: the building and the outdoor unit position decide it. Central Harwell is a short walk from the Harwell Conservation Area. 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 the local planning authority (for Harwell, usually Vale of White Horse council) first.
How much time does a heat pump install need?
An installation takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. The survey lets us set a firm programme, and you can phone 07833 053749 to book it.
Can you set up regular servicing?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Every visit is recorded and F-Gas records kept where they apply.
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. At the end, we clear up and show you what we’ve done.
Do I need new radiators for a heat pump?
The heat loss survey answers that, room by room. Where a radiator is already large enough, it stays, and any that need upsizing are set out in the 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.
How it works
You do not need to do much on the day. Someone needs to let us in and show us the units, or where they’re going, and we take it from there. At the end, we tidy up and run through the work with you. Around Harwell, access is normally simple, though gates and garden access are worth mentioning.
- First we talk through the property and the current system.
- 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.
Getting ready for the visit
- Keep pets out of the rooms we’re working in
- Tell us about parking and loading
- Let us know if the building has a permit or sign-in process
Ask for a quote
Every quote starts with a look at the job, either on a site survey or, for simple jobs, from your pictures and details. Then you get a fixed price so you know the cost before we begin.

Air source heat pumps around Harwell

Better insulated, newer homes are often a good match for a heat pump. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
A heat loss calculation decides the size of heat pump your home needs. Older homes near Church of St Matthew may need extra checks for planning and heat loss before a heat pump is designed.

A customer’s words
“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.”
