How we handle air source heat pumps in Petersham
Installing an air source heat pump in a home is zero-rated for VAT until 31 March 2027, then 5%. That follows HMRC Notice 708/6, and it doesn’t apply to businesses. For air-to-air systems, we confirm the VAT on your quote. This is general information, not tax advice. If the problem is deciding on the outdoor unit position and comparing heat pump types, we can sort it out.
In a London area like Petersham, many homes are flats or terraces with little outside space, and that decides which kind of heat pump works. An air-to-water system needs space outside and usually a hot water cylinder inside, while an air-to-air system needs less space.
Equipment warranty comes from the manufacturer, on its own terms, and we set them out on your quote. Terms differ from brand to brand, and we are happy to talk you through them.

Common questions in Petersham
Will a heat pump in Petersham need planning permission?
The answer turns on the property and where the outdoor unit would sit. The Petersham Conservation Area takes in the middle of Petersham. Heat pumps on houses are often permitted development, but listed buildings need consent and conservation areas restrict outdoor units facing a road. Where it’s needed, we check with the planning department at Richmond-Upon-Thames council, usually the authority for Petersham.
Do I need permission to put air conditioning in my flat in Petersham?
Normally, yes, though leaseholders normally need the freeholder’s agreement. We look at where the outdoor unit could go, such as a balcony, flat roof or rear wall, and write it up for the freeholder or agent.
Am I eligible for a heat pump grant?
Eligibility depends on the property and the scheme rules. The scheme gives £7,500 for eligible air-to-water or ground source systems, and £2,500 for air-to-air only under strict conditions. We check before you commit.
Which brands do you work with?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For new systems, we recommend a brand and model to suit the job and tell you why.
Can we book visits on a schedule?
Yes. We offer maintenance contracts, with visits at the interval your system and the manufacturer need. Each visit is recorded, with F-Gas records where refrigerant work is involved.
Do you provide F-Gas records?
Yes, on every job. New installations come with commissioning details, F-Gas records and warranty information, while repairs and services get a written note of what was found and done.
What VAT do I pay on a heat pump?
Not on a home installation at the moment: until 31 March 2027 the rate is 0% in residential accommodation, then 5%. The relief is not available to businesses, and with air-to-air we confirm the VAT on the quote. This is general information, not tax advice.
What a heat pump looks like in Petersham
Valuation Office Agency council tax records put about 48% of homes across Petersham and its surrounding area before 1919, and the last census (2021) found about 50% of households live in flats. Period properties can still suit a heat pump, but the design has to start from accurate heat loss figures. A flat may have no room for a hot water cylinder, and the freeholder usually has a say on the outdoor unit, which can tip the choice towards air-to-air. For a London home, the outdoor unit position and the MCS noise check need careful planning.
If you live near St Margarets (London) station, the survey compares air-to-water and air-to-air for your home before anything is quoted. If your home is one of the older properties near St Peter's Church, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.

What the work involves, system by system
Radiators and underfloor heating
Heat pumps run at lower flow temperatures, so radiators may need to be larger so we check them against each room’s heat loss.
Heat loss surveys
A heat loss survey measures how much heat each room loses on a cold day. It’s the basis for sizing the heat pump and the radiators.

What happens on the day
Refrigerant work is done by qualified engineers working for an F-Gas certified company, and electrical work is done by us as NICEIC approved contractors. So on the day, you do not need a separate electrician for the electrical side. The work 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. A note on parking and access helps us plan a visit to Petersham.
- It begins with your house and the heating it relies on now.
- 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.
- Then it’s fitted, commissioned and registered with MCS.
How to prepare
- Make sure we can reach the outdoor unit, or where it will go
- Plan for pets to be kept clear during the visit
- Have the make and model of any existing unit to hand
