What affects the quote in Mayes Green
Before we fix a price, we need to know a few things. We check:
- The equipment or parts the job needs
- How many units are involved
- The distance and route between the indoor and outdoor units
The pipe route, the height of the units and how we reach them can all change the price. We take each of them into account, and the price is fixed before work begins.
What we need to know
A few details help us quote accurately. With your enquiry, please include:
- The outside wall, roof or yard where the outdoor unit sits or would go
- A close-up of the unit’s label showing the model number
- A short video of any fault, such as a noise or a flashing light
VAT is set out clearly on every quote, with the rate that applies to your job. Homes, businesses and different kinds of work can be treated differently for VAT, so we confirm it in writing rather than guess. For a fixed-price quote, call us on 07833 053749, or email if that’s easier.
How we handle air source heat pumps in Mayes Green
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 checking emitters for a heat pump and an oil, LPG or gas boiler near the end of its life, across air-to-air heat pumps, underfloor heating and air-to-water heat pumps.
If your home in or near Mayes Green is heated by oil, LPG or electric heaters with no mains gas, the Boiler Upgrade Scheme adds an extra £1,500 until March 2027 for an air source or ground source heat pump.
We’re an F-Gas certified company, NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Our engineers hold the F-gas qualifications needed to work on refrigerant.

Mayes Green: your questions answered
Does the Boiler Upgrade Scheme cover homes in Mayes Green?
Mayes Green is in England, where the Boiler Upgrade Scheme runs. Air-to-water and ground source systems attract £7,500. Air-to-air gets £2,500, but only where it takes over from fossil-fuel heating and covers the whole home’s heating demand. You do not apply yourself: the MCS certified installer does, which is us.
Do you cover smaller places like Mayes Green?
Yes. Mayes Green is within the area we cover across London and the South East. Send a few details and pictures, and we reply the same working day.
How quickly will you reply?
You’ll hear from us the same working day. For a breakdown that cannot wait, call our 24/7 emergency line.
Which manufacturers do you install and repair?
We work with the leading brands, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
Will my radiators work with a heat pump?
We find out during the survey. Rooms where the radiator is big enough stay as they are, and any that need upsizing are set out in the quote.
Will I get records for the system?
Yes. You get a written record of each visit, and any work on the refrigerant circuit goes in the F-Gas records. File them with the system’s paperwork.
Do you protect the property while you work?
We start with protection: sheets over the floor and nearby furniture. Holes and fixings are agreed with you, and we clean up afterwards when we finish.
What air conditioning will not do
Some problems need a different service or another trade:
- Planning decisions, which rest with the council
- Draught-proofing and insulation upgrades
- Disconnecting or servicing a gas boiler
If you are not sure, just ring us on 07833 053749 or send an email and we will give you a straight answer before you book.

Heat pumps in Mayes Green: local notes
Listed buildings are part of the picture here: about 6 within half a mile of the centre, such as Shoes Farm House (grade II). For a heat pump, permitted development doesn’t apply within the grounds of a listed building, and in a conservation area the outdoor unit can’t go on a wall or roof facing a road, so we check with the planning team at Mole Valley council, which typically handles Mayes Green where needed. The Valuation Office Agency’s council tax figures put about 40% of homes across Mayes Green and its surrounding area before 1919, and Census 2021 figures found about 76% of households in detached or semi-detached houses. In older homes, the heat loss calculation is especially important, as solid walls and draughts change the size of heat pump needed. Detached and semi-detached houses normally have room for the outdoor unit and a cylinder.
Period properties close to Church of St John the Baptist can suit a heat pump, though insulation and any heritage protection are checked first. A heat loss calculation decides the size of heat pump your home needs.

How the visit works
Our engineers arrive at the time agreed with you and run through the plan before anything else. Floors and furniture near the work are covered with dust sheets, and anything electrical is made safe before work starts. The work itself takes anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes. For a village like Mayes Green, tell us about narrow lanes, gates and parking when you book.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- On the visit we calculate what every room loses on a cold day, then check the radiators, room for a cylinder and outdoor unit options.
- A fixed-price quote follows, setting out the system, any grant that applies and the VAT.
- We fit the outdoor unit and connect it to the heating, hot water and controls.
- Commissioning, MCS certification and a handover of the controls finish the job.
Before we arrive
- Dig out any previous service or F-Gas records
- Move furniture away from the wall where we will be working
- Tell us about access, such as roof hatches, high walls or locked plant areas
Getting a quote
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 simple jobs can often be priced without a visit.
