Air source heat pumps in St John's, done properly
In England, an air source heat pump on a house can often go in under permitted development rights. The conditions include an outdoor unit of no more than 1.5 m³ and compliance with MCS 020(a), and the unit can’t be used solely for cooling or sit within the curtilage of a listed building. We check the rules for your property as part of the survey. If you’re dealing with plans to switch to electric heating with a heat pump and not knowing whether a grant applies, we can sort it out.
If your home near St John's has no mains gas, the grant can be bigger. Homes heated by oil or LPG with no mains gas can get an extra £1,500 on the Boiler Upgrade Scheme until March 2027.
Refrigerant work is written up in the F-Gas records: the work carried out, the refrigerant involved and the quantities. Keep the records with the manual and the warranty documents, ready for the next service or a warranty query.

What else we do in St John's
Owner checks or an engineer?
Keep a note of anything odd: error codes, noises, drips, smells or a drop in performance. It makes our diagnosis quicker, and a photo of the display helps even more.
Owners can handle the everyday basics: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Opening up the units, the electrics and the refrigerant circuit are a job for us.
How it works
You don’t need to do much on the day. Someone needs to let us in and show us the units, or where they’re going, and the rest is down to us. Before we leave, the area is tidied and we explain what we have done. Photos of the room and the outside wall help us plan a job near St John's.
- First, a chat about the property and your goals for the heating.
- 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.
- We install the heat pump and connect it up.
- We commission it, complete the MCS certificate and show you how to use it.
Before we arrive
- Tell us about parking and loading
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Name a contact who can meet us at the agreed time

Advice
Air source heat pumps in St John's: the local picture
At about 25 miles from central London, St John's sits inside the area we cover across London and the South East. The centre of St John's lies within the St John's, Woking Conservation Area. In the mile around St John's’s centre, 4 conservation areas have been designated. Woking Crematorium Chapel, listed at grade II, is one of roughly 6 protected buildings and structures in the half-mile around St John's’s centre. For a heat pump, permitted development doesn’t apply within the grounds of a listed building, and in a conservation area the outdoor unit cannot go on a wall or roof facing a road, so we check with the local planning authority (typically Woking council) where necessary.
Live in one of the older houses around St John's Church? Expect the survey to look closely at heat loss and at the building’s planning status. Sizing comes from the heat each room loses on a cold day, not from the size of the old boiler.

Questions from St John's
Is the heat pump grant available in St John's?
St John's is in England, where the Boiler Upgrade Scheme runs. 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 you cover smaller places like St John's?
Yes. St John's is within the area we cover across London and the South East. Visits to smaller places are planned so the engineer arrives with what the job needs.
Is the equipment covered by a warranty?
It’s the manufacturer’s warranty, which varies by brand. For instance, Daikin’s standard warranty on split air conditioning is 2 years, and we explain the terms for whichever brand you choose.
Do you work on all makes?
We install and work on the leading makes, 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.
Can we book visits on a schedule?
Yes. We offer maintenance contracts, set at the interval the system and the manufacturer’s terms need. Each visit is recorded, with F-Gas records where refrigerant work is involved.
Do you work for landlords and businesses?
Yes. Homeowners, landlords, agents and businesses all book us in St John's and across Surrey. Let us know who the records should go to.
What’s the difference between air-to-water and air-to-air heat pumps?
Air-to-water replaces the boiler for heating and hot water, while air-to-air heats and cools rooms, and we help you choose. We install both types.
Why it’s worth doing now in St John's
From 1 April 2027, VAT on heat pumps in homes rises from 0% to 5%. If you’re thinking about a heat pump, that date is worth knowing alongside your own plans for the property. Getting the date in early helps for a job in a place like St John's.
What you pay depends on the type of system and how many units are involved, how easy the units are to reach and what the work involves. You get a fixed price before we start, so you know where you stand.
