How we handle air source heat pumps in Knowle
Air source heat pumps collect heat from outdoor air and bring it inside with electricity running the compressor and fans. The technology is close to air conditioning, which is why we install both and the Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning. Common call-outs are for working out where a cylinder could go and wanting to stop using oil, LPG or gas for heating, on hot water cylinders, air-to-water heat pumps and air-to-air heat pumps.
Older and listed homes in villages like Knowle need extra care, and permitted development doesn’t cover listed buildings, so consent comes first.
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. For any other brand, we explain the manufacturer’s terms on your quote.

Outdoor unit position and planning
Permitted development conditions in England include an outdoor unit of no more than 1.5 m³ and must meet MCS 020(a) and not be used solely for cooling. Listed building curtilages are excluded.
VAT on heat pumps
This is general information, not tax advice.
What you can do yourself, and what needs us
Never try to top up, release or handle refrigerant yourself. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and refrigerant lines can cause cold burns. A suspected leak is our job, not yours.
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. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Air source heat pumps around Knowle
About 53% of homes in and around Knowle have been built since 2000, according to VOA council tax data, and about 61% of households live in detached or semi-detached houses, according to Census 2021 figures. Lower heat loss in recent homes often means a smaller heat pump and fewer radiator changes. Houses typically have space for an outdoor unit and a hot water cylinder.
Sizing comes from the heat each room loses on a cold day, not from the size of the old boiler. Period properties close to Church of St Francis can suit a heat pump, though insulation and any heritage protection are checked first.

What happens on the day
The work area is kept tidy throughout, with sheets down and mess cleared as we go. If we need to drill through a wall, we agree the spot with you first. On site, it takes from a couple of days to around a week, depending on the system and how much of the heating changes. For a village like Knowle, tell us about narrow lanes, gates and parking when you book.
- It begins with your house and the heating it relies on now.
- A heat loss survey is carried out, room by room.
- From those figures we size the heat pump and decide on radiators, cylinder and outdoor position.
- A fixed-price quote explains the cost, the grant position and the VAT.
- Then it’s fitted, commissioned and registered with MCS.
How to prepare
- Name a contact who can meet us at the agreed time
- Mention any roof access, ladders or high-level work
- Make sure we can reach the outdoor unit, or where it will go

Advice
Managing agents and facilities teams in Knowle
If you look after several properties, we can plan visits across the portfolio and price them together. Each property gets its own records, so the files stay tidy.
Portfolio owners often want one contractor and one number. Our area covers Greater London and the South East, so a run of properties can go into one programme and kept to a regular schedule.
Common questions in Knowle
Do you cover smaller places like Knowle?
Yes, smaller places are covered as well as towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
Do I need planning permission for a heat pump in Knowle?
That depends on the building and where the outdoor unit goes. The half-mile around the middle of Knowle holds about 4 listed buildings and structures. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights don’t reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask the planning department at Winchester City council, normally the authority for Knowle.
How long does a heat pump installation take?
The work takes from a couple of days to around a week, depending on the system and how much of the heating changes. The survey lets us set a firm programme, and you can phone us on 07833 053749 or send an email to book it.
Am I eligible for a heat pump grant?
We check the scheme rules for your property before you go ahead. The installer applies for the grant, so we handle the application if you’re eligible.
Will you work on another installer’s system?
Yes. We work on systems fitted by other installers as well as our own, on all the main brands. Tell us the make and model and send any paperwork you have.
Which type of heat pump is right for my home?
The right choice depends on the property and what you need. The grant is £7,500 for eligible air-to-water systems and £2,500 for air-to-air in limited cases, and we set out the options after the survey.
Which manufacturers do you install and repair?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For a new system, we suggest the make and model that suit the property and tell you why.
