Brill air source heat pumps
Air source heat pumps for Brill, from F-Gas certified engineers, with warranty terms explained brand by brand. Enquiries answered the same working day.
- Working out whether radiators need upsizing

What happens if it’s left?
A heat pump sized without a proper heat loss survey can struggle in cold weather or run inefficiently. A room-by-room survey gets it right first time. An early booking makes the visit to Brill easier to arrange.

About our air source heat pumps in Brill
We begin with a room-by-room heat loss survey. It shows how much heat each room needs on a cold day, so the heat pump and the radiators or indoor units can be sized properly. Guesswork leads to systems that are too big or too small. The work covers homes heated by oil, LPG or gas, radiator systems and underfloor heating, and the jobs we see most are deciding on the outdoor unit position and deciding which kind of heat pump suits the home.
In a place like Brill, some homes are listed, because permitted development does not apply within the grounds of a listed building, so consent comes first.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We will explain how the manufacturer’s terms are likely to apply before any chargeable work goes ahead.

For landlords and property managers
Running several properties is easier with one contractor. Our area covers Greater London and the South East, so a run of properties can go into one programme and kept on a regular cycle.
If you look after several properties, we can plan visits across the portfolio and price them together. Each property gets its own records, so each one has its own history.

Air source heat pumps in Brill: the local picture
The last census (2021) found about 85% of households in detached or semi-detached houses. Houses normally have space for an outdoor unit and a hot water cylinder.
Older homes near United Reformed Church may need extra checks for planning and heat loss before a heat pump is designed. Boarstall Tower, roughly 1.9 miles west, is a reminder to check your home’s listing status: permitted development doesn’t cover listed buildings.
Brill is about 6 miles north-west of Thame, in Buckinghamshire. We cover Brill for air source heat pumps and across the rest of Buckinghamshire. Brill is one of 263 places in Buckinghamshire where we work for homes and businesses. Guildford, roughly 45 miles off, has its own page on this site.
Jobs in HP18 are looked at, quoted and booked the same way as anywhere else. You will find streets such as High Street, The Square and Brae Hill, and we cover them all. Places around Brill that are also on our list: Little London (1 mile south-west), Oakley (1 mile south-west), Piddington (2 miles north), Ludgershall (2 miles north) and Blackthorn (4 miles north-west).

How the visit works
The visit has three parts, a bit like a doctor’s appointment: diagnose, treat and sign off. First comes a careful look at the system or the space, then we do the work, and finally everything is tested, recorded and explained. Most of the time goes on the middle part, which takes a few days for most air-to-water installations, with air-to-air systems often quicker. Photos of the room and the outside of the property help us plan a visit to Brill.
- 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 recommend air-to-water or air-to-air and check the grant position.
- Installation follows on the agreed dates.
- After commissioning, you get the MCS certificate and a handover.
How to prepare
- Make sure someone can let us in at the agreed time
- Mention any parking restrictions near the property
- Mention any managing agent or landlord rules we need to follow

Published ranges are a starting point; the quote is built on your property, because no two buildings, rooms or systems are the same. After a look at the job, by pictures or a survey, the price is fixed. To get going, give us a ring on 07833 053749, or email if that’s easier.
Advice
Your questions about air source heat pumps in Brill
Can I get the Boiler Upgrade Scheme grant in Brill?
Brill is covered, as the scheme runs across England and Wales. 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 Brill?
It depends on the property. Central Brill sits inside the Brill Conservation Area. A heat pump on a house can be permitted development if it meets the conditions, including the MCS noise check, but not within the grounds of a listed building, and in a conservation area the outdoor unit cannot face a road. Where needed, we check with the local planning authority (for Brill, normally Buckinghamshire council).
Will my radiators work with 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.
Do you look at the job first?
Yes, every time. Diagnosis comes before treatment: the survey shows what’s needed, where things go and what access we need, and the quote is based on that.
Can I do the refrigerant work myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That is the law, not just our preference, and manufacturers expect it for their warranty too. We can quote for the whole job, from supply to commissioning.
Who is responsible for leak checks?
The operator of the equipment, working with qualified engineers. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We can tell you which band your system falls into.
Do you work for landlords and businesses?
Yes. Homeowners, landlords, agents and businesses all book us across London and the South East. Let us know who the records should go to.
What the work involves, system by system
Hot water cylinders
An older cylinder may not suit a heat pump and we tell you if it needs replacing.
VAT on heat pumps
Installing an air source heat pump in a home is zero-rated until 31 March 2027, then 5%, under HMRC Notice 708/6. It does not apply to businesses.
From one of our customers
“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.”
