Air source heat pumps in Downham

Air source heat pumps in Downham: the local picture

About 72% of homes in and around Downham were built between the wars, according to the Valuation Office Agency’s council tax figures, and the last census (2021) found about 42% of households in terraced houses. For homes of that age, the survey checks the insulation, the radiators and the hot water setup. Terraced houses share walls with neighbours, which helps, but the outdoor unit position needs care with noise next door. For a London home, the outdoor unit position and the MCS noise check need careful planning.

With Bromley Palace about 1.7 miles south-east, it’s worth asking whether your own home is listed before planning a heat pump.

Downham is about 2 miles north of Bromley, in Greater London. Whether you are in the middle of Downham or further out, we cover air source heat pumps, from a single room to a whole building. Count every place we list in Greater London and you reach 764, with Downham on the list.

How we handle air source heat pumps in Downham

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, and for air-to-air systems we confirm the VAT on your quote. Please treat this as general information rather than tax advice. Common call-outs are for deciding on the outdoor unit position and deciding which kind of heat pump suits the home, on underfloor heating, homes heated by oil, LPG or gas and air-to-air heat pumps.

In a flat in Downham, the lease and the freeholder usually decide where a heat pump can go. The planning rules for flats are stricter than for houses, so we check the position before we design.

Looking after a system is mostly common sense: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. That also helps where the warranty terms ask for regular servicing.

Rented and managed buildings

We work for landlords, letting agents and managing agents as well as homeowners and businesses. Tell us who the contact on site is and who should receive the paperwork, and we’ll keep everyone informed.

Facilities teams in offices, schools and public buildings book us too across Greater London. Work can be phased by floor, zone or building around the people who use them.

What we’re called out for in Downham

Extensions, renovations and loft conversions are a natural time to rethink the heating. It’s simpler to plan radiators, pipework and a cylinder while the builders are in.

These are the situations we see most often:

  • Replacing a combi boiler with a heat pump
  • Deciding on the outdoor unit position
  • Choosing between air-to-water and air-to-air

If your home is one of the older properties near St Barnabas, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.

What your quote should include

  • The make and model of any parts or equipment being quoted
  • Whose warranty applies, and on what terms
  • Whether testing, commissioning and paperwork are included

How to choose an air conditioning engineer

How it works

Our engineers arrive at the time agreed with you and run through the plan before anything else. Floors and furniture near the work are covered with dust sheets, and anything electrical is made safe before work starts. On site, it 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. In a London area like Downham, parking and access are worth sorting out before the day.

  1. It begins with your house and the heating it relies on now.
  2. Every room’s heat loss is worked out on site.
  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.

Getting ready for the visit

  • Plan for pets to be kept clear during the visit
  • Let us know if the building has a permit or sign-in process
  • Give us access to the outside wall, roof or yard where the outdoor unit sits

Advice

Downham questions

Can you fit air conditioning in a London flat in Downham?

In many cases, yes, once the lease and the building’s rules are checked. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.

Can you do air source heat pumps in Downham?

We do: Downham falls inside our working area. Tell us a little about the job and we will take it from there.

Does the grant cover air-to-air heat pumps?

There is a £2,500 grant for air-to-air, but only under strict conditions. It has to replace the fossil-fuel heating, meet the full heating demand, be fitted by an MCS certified installer, and be in a home.

Can I get the Boiler Upgrade Scheme grant?

Eligibility depends on the property and the scheme rules. In England and Wales, the scheme offers £7,500 towards an eligible air-to-water or ground source heat pump, and £2,500 towards an air-to-air heat pump only in limited cases. We check before you commit.

How quickly will you reply?

We reply to enquiries the same working day. If it’s an emergency, ring the 24/7 line instead.

How long will it take to install a heat pump?

The work takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. The survey lets us set a firm programme, and you can call 07833 053749, or email if that’s easier to book it.

Which manufacturers do you install and repair?

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

What air source heat pumps can’t fix

We won’t sell you work that does not address the problem, so these are the things it won’t cover:

  • Draught-proofing and insulation upgrades
  • A grant for a home that does not meet the scheme rules
  • Tax advice on your own circumstances

If in doubt, call us on 07833 053749 or drop us a line and we’ll say what we think before booking.

Where we work

  • Radiator systems
  • Air-to-air heat pumps
