Air source heat pumps for Lewknor

Landlords, agents and facilities managers

Larger air conditioning systems in buildings need more than servicing: a TM44 inspection by an accredited energy assessor is required at least every 5 years for systems over 12 kW. We can arrange it, prepare the system for it and fix what it finds.

We also work for facilities teams in offices, schools and public buildings in Lewknor and across Oxfordshire. Work can be phased by floor, zone or building around the people who use them.

Air source heat pumps in Lewknor, done properly

A heat pump takes heat from the outside air and moves it into your home, using electricity to drive the process. It works on the same principle as air conditioning, run the other way and the Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning. If the problem is questions about listed buildings or conservation areas and questions about where the outdoor unit can go, we can sort it out.

For a home around Lewknor that is off mains gas and heated by oil or LPG, an extra £1,500 is available through the Boiler Upgrade Scheme until March 2027, on top of the £7,500.

Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we set them out on your quote. Each brand sets its own conditions, so we go through them with you rather than leave you to find the small print.

What we do, step by step

Our engineers bring the tools, gauges and access equipment the job needs. All we ask is clear access to the units, or to where they’ll go, and to the consumer unit. The visit takes a few days for most air-to-water installations, with air-to-air systems often quicker. Somewhere like Lewknor, it helps to know about lanes, gates and where to park.

  1. It begins with your house and the heating it relies on now.
  2. A heat loss survey is carried out, room by room.
  3. From those figures we size the heat pump and decide on radiators, cylinder and outdoor position.
  4. A fixed-price quote explains the cost, the grant position and the VAT.
  5. We install, commission and register the system under MCS.

Preparing for the visit

  • Tell us about access, such as roof hatches, high walls or locked plant areas
  • Give us access to the outside wall, roof or yard where the outdoor unit sits
  • Let us know where we can park and unload

What affects the quote in Lewknor

The price is fixed before any work begins. It’s based on:

  • Whether it’s a simple split or a larger system
  • The number of rooms, units or zones
  • What we find on the survey or diagnosis

Putting the work off seldom saves money. Small problems, from blocked filters to slow leaks, tend to get worse, and a struggling system uses more electricity to do less. If you are unsure, phone us on 07833 053749 or email us and we’ll give you an honest view and a fixed price.

What we need to know

Photos let us diagnose from a distance. Try to include:

  • The paperwork from the last service, if you have it
  • The postcode and whether it’s a home, flat or business
  • A short video of any fault, such as a noise or a flashing light

Every quote starts with a look at the job, from a site survey or, where the job is straightforward, from photos and measurements. After that, we send a fixed price before any work starts.

Homes in Lewknor and heat pumps

Central Lewknor is inside the Lewknor Conservation Area. Listed buildings are part of the picture here: about 18 within half a mile of the centre, such as Church of St Margaret (grade I). Where a home is affected, the outdoor unit position is settled with the planning team at South Oxfordshire council, which typically handles Lewknor before the heat pump design is finished. About 36% of homes across Lewknor and its surrounding area were built before 1919, according to Valuation Office Agency council tax records, and the last census (2021) found about 78% of households in detached or semi-detached houses. Older homes can lose heat faster, so a room-by-room heat loss calculation, and sometimes insulation or larger radiators, comes before sizing a heat pump. Houses usually have space for an outdoor unit and a hot water cylinder.

With Adwell House about 1.6 miles north-west, it’s worth asking whether your own home is listed before planning a heat pump.

FAQs for Lewknor

Do you cover smaller places like Lewknor?

Yes, smaller places are covered as well as towns. Visits to smaller places are planned so the engineer arrives with what the job needs.

Can I get the Boiler Upgrade Scheme grant in Lewknor?

Yes, the scheme covers homes in England, including Lewknor, if they qualify. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. The installer applies, and we are MCS certified.

Which manufacturers do you install and repair?

We install and work on the leading makes, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we will take it from there.

Do you work for landlords and businesses?

Yes. Homeowners, landlords, agents and businesses all book us across London and the South East. Tell us who should receive the paperwork.

Do you provide F-Gas records?

Yes, always. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, and repairs and services get a record of the work.

How quickly will you reply?

The same working day. After that, we agree a survey, diagnosis or installation date that suits you, with a fixed price before work starts.

Will skipping a service affect the warranty?

Check the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so check the terms or ask us. Either way, keep a record of every service.

Common problems we fix in Lewknor

Homes off the gas grid, heated by oil or LPG, are often good candidates to look at. Until March 2027, an extra £1,500 is available for air source and ground source heat pumps in homes heated by oil or LPG with no mains gas, subject to the scheme rules.

Most people get in touch when they notice one of these:

  • Questions about where the outdoor unit can go
  • Not knowing whether a grant applies
  • A boiler that is getting old

Live in one of the older houses around Church of St Margaret? Expect the survey to look closely at heat loss and at the building’s planning status.
