Landlords, agents and facilities managers
Where a tenant occupies the property but the landlord owns the system, the lease or tenancy agreement normally sets out who maintains what. We are happy to deal with either side, and the paperwork can go to both.
Portfolio owners often want one contractor and one number. We work across London and the South East, so work at different addresses can be planned together and kept on a regular cycle.
Air source heat pumps for homes and businesses in Wallington
As an MCS certified installer, we fit air source heat pumps for homes in Wallington and the rest of Greater London. Air-to-water systems feed your radiators or underfloor heating and hot water cylinder, while air-to-air systems heat rooms directly through indoor units and can cool them too. We’ll explain which type fits your home and why. The work covers hot water cylinders, underfloor heating and air-to-water heat pumps, and the jobs we see most are choosing between air-to-water and air-to-air and radiators that may be too small for a heat pump.
A terrace in Wallington shares walls with its neighbours, which helps keep heat in, provided the outdoor unit can sit somewhere that passes the MCS noise check.
Each manufacturer sets its own warranty period. For instance, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. Whatever the brand, the manufacturer’s terms are explained on your quote.

Wallington questions
Is the heat pump grant available in Wallington?
Yes, the scheme covers homes in England, including Wallington, if they qualify. The amount depends on the type of heat pump, and the survey confirms which applies. You don’t apply yourself: the MCS certified installer does, which is us.
Is planning permission needed for a heat pump in Wallington?
It depends on the property. The centre of Wallington is in a 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 planning department at Sutton council, normally the authority for Wallington first.
Can landlords and managing agents book you?
Yes. From one rented home to commercial buildings, we work the same way: survey or diagnosis, a fixed price and proper paperwork.
Can you look at a system you didn’t fit?
Yes. We start with a proper look and tell you honestly what we find, including any issues with how it was fitted. Any work is priced before it goes ahead.
Does servicing affect my warranty?
It can, for some brands. Send us the make and model and we will tell you what the manufacturer expects, and book the service at the interval they recommend.
Do you cover Wallington?
Yes. Wallington is part of the area we cover, as part of our area across London and the South East. Our base is in East Grinstead, West Sussex.
Will I get records for the system?
Yes, on every job. New installations come with commissioning details, F-Gas records and warranty information, and repairs and services get a record of the work.

VAT on heat pumps
HMRC says most air conditioning units are air source heat pumps, but each case depends on the facts, so we confirm the VAT on your quote.
Air-to-water heat pumps
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes), before the grant. Eligible homes in England and Wales can get a £7,500 Boiler Upgrade Scheme grant towards it, and we apply for it as the installer.

What we do, step by step
We keep the work area tidy as we go, with dust sheets down and offcuts and packaging cleared up. If we need to drill through a wall, we agree the spot with you first. On site, it takes a few days on site, depending on the cylinder, the radiators and the pipework involved. If a freeholder or agent needs to agree the work in Wallington, we can send them the details.
- First we talk through the property and the current system.
- We measure heat loss for every room.
- 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.
Preparing for the visit
- Make sure we can reach the consumer unit or fuse board
- Find the manual or the paperwork for the system, if you have it
- Let us know if the building has a permit or sign-in process
