Windmill Hill questions

Can I get the Boiler Upgrade Scheme grant in Windmill Hill?

Windmill Hill is covered, as the scheme runs across England and Wales. It gives £7,500 towards an air-to-water or ground source heat pump, or £2,500 towards an air-to-air heat pump that replaces the fossil-fuel heating and meets the whole home’s heating need. The installer applies, and we are MCS certified.

Do you cover Windmill Hill for air source heat pumps?

We do: Windmill Hill falls inside our working area. Get in touch with the details and we reply the same working day.

Do you look at the job first?

Yes. Photos often do the job for simple work, while larger systems and faults that need testing are seen on site.

Why use an F-Gas certified company?

Companies working on equipment that contains F gas must be certified by an approved body, and the engineers need their own qualifications. It means the refrigerant in your system is handled legally.

Who is responsible for leak checks?

The F-gas rules share it between the equipment’s operator and the engineers who work on it. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.

Can you look at a system you didn’t fit?

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.

What accreditations do you have?

F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, plus Checkatrade membership. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.

About our air source heat pumps in Windmill Hill

In England, an air source heat pump on a house can often go in under permitted development rights. Conditions include a maximum outdoor unit size of 1.5 m³, compliance with MCS 020(a), use for more than cooling alone and a site outside the curtilage of a listed building. We look at the planning position for your home during the survey. If you are dealing with ageing boilers that will need replacing and no space for a hot water cylinder, we can sort it out.

Space for an outdoor unit is rarely an issue near Windmill Hill, so the design comes down to heat loss, radiators and hot water.

We’re an F-Gas certified company, NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

What the work involves, system by system

Air-to-water heat pumps

Flow temperatures are lower than with a typical boiler, so radiator sizes matter.

VAT on heat pumps

Installing an air source heat pump in a home is zero-rated until 31 March 2027, then 5% following HMRC’s rules on energy-saving materials. It doesn’t apply to businesses.

What we do, step by step

Our engineers bring the tools, gauges and access equipment the job needs. You only need to give us clear access to the units, or their planned positions, and to the fuse board. The visit takes a few days for most air-to-water installations, with air-to-air systems often quicker. Somewhere like Windmill Hill, it helps to know about lanes, gates and where to park.

  1. We talk through your home, your current heating and what you want from a heat pump.
  2. A heat loss survey works out how much heat each room needs, and we look at the radiators, the cylinder space and where the outdoor unit could go.
  3. A fixed-price quote follows, setting out the system, any grant that applies and the VAT.
  4. The outdoor unit, the indoor equipment and the controls are installed and connected.
  5. We commission the heat pump, complete the MCS paperwork and talk you through the controls.

How to prepare

  • Find the manual or the paperwork for the system, if you have it
  • Move furniture away from the wall where we’ll be working
  • Let us know where we can park and unload

Getting a quote

Here’s what helps us quote: where the property is and what kind of building it is, a few photos, the make and model of any existing system and any symptoms, from error codes to drips. Then ring us on 07833 053749 or write to us at info@aircondoctor.co.uk.

Safe owner checks

Refrigerant is off limits for anyone without the right qualifications. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and refrigerant lines can cause cold burns. A suspected leak is our job, not yours.

Keep a note of anything odd: error codes, noises, drips, smells or a drop in performance. It makes our diagnosis quicker, and a photo or a short video of the display is even better.

What air conditioning won’t do

An honest diagnosis matters more to us than a booking, so here’s what air source heat pumps won’t do:

  • Draught-proofing and insulation upgrades
  • Any gas work on the existing boiler
  • Grants for hybrid systems or replacements of low-carbon systems

If you are not sure, just call us on 07833 053749 or fill in the contact form and we’ll give you a straight answer before booking.

Air source heat pumps in Windmill Hill: the local picture

About 42 miles out from central London, Windmill Hill is part of the South East area we work across. About 42% of homes in the Windmill Hill area date from 1945 to 1972, according to VOA council tax data, and the last census (2021) found about 79% of households in detached or semi-detached houses. For homes of that age, the survey checks the insulation, the radiators and the hot water setup. Detached and semi-detached houses typically have room for the outdoor unit and a cylinder.

Period properties close to Parish Church of All Saints (inworth) can suit a heat pump, though insulation and any heritage protection are checked first. Layer Marney Tower, roughly 2.9 miles east, is a reminder to check your home’s listing status: permitted development does not cover listed buildings.
