About our air source heat pumps in Heston
Air-to-water heat pumps heat your hot water through a cylinder. Homes with a combi boiler may not have a cylinder, so finding space for one is part of the survey. Air-to-air systems do not heat hot water, so you’ll need another way to do that. Typical jobs include planning and permitted development questions and comparing heat pump types, across air-to-water heat pumps, hot water cylinders and underfloor heating.
A terrace in Heston shares walls with its neighbours, which helps keep heat in, provided the outdoor unit can sit somewhere that passes the MCS noise check.
Whatever the visit, you get a written record: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. Keep it with the system’s paperwork so it’s to hand next time.

Your questions about air source heat pumps in Heston
Is the heat pump grant available in Heston?
Yes, the scheme covers homes in England, including Heston, if they qualify. The grant is £7,500 for an air source (air-to-water) heat pump and £2,500 for an air-to-air system that replaces the existing fossil-fuel heating. You do not apply yourself: the MCS certified installer does, which is us.
Can you fit air conditioning in a London flat in Heston?
Usually, yes, though leaseholders normally need the freeholder’s agreement. 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.
What’s the price of a heat pump installation?
For air-to-water, it’s £8,000–£16,000 (0% VAT on homes) before any Boiler Upgrade Scheme grant. Air-to-air prices are set after a survey, and we confirm the VAT on the quote.
How do you keep the place clean during the work?
We start with protection: sheets over the floor and nearby furniture. Holes and fixings are agreed with you, and we clean up afterwards before we leave.
Do I get paperwork after the visit?
Yes, on every job. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, while repairs and services get a written note of what was found and done.
Do you work on all makes?
We install and work on the leading makes, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.
Can we book visits on a schedule?
Yes. Send details of the systems and how they’re used and we will propose a schedule and quote for it. That can include the leak checks the F-gas rules require for larger systems.
When to call us in Heston
A common reason is wanting to stop burning gas, oil or LPG. With a heat pump, the heat comes from the air outside and the system runs on electricity and that’s the appeal for many households.
These are the situations we see most often:
- Questions about where the outdoor unit can go
- Plans to switch to electric heating with a heat pump
- Not knowing whether a grant applies
Osterley House lies about 1.2 miles east. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions.
What your quote should include
- Whether the electrical work is done by a registered contractor, such as NICEIC approved
- Which brand and model they’re proposing, and why
- Whether the price is fixed or an estimate
Heat pumps in Heston: local notes
Valuation Office Agency council tax records show about 44% of homes across Heston and its surrounding area date from 1919 to 1939. For homes of that age, the survey checks the insulation, the radiators and the hot water setup. London homes can be short of space for an outdoor unit and cylinder, which affects the choice of heat pump.
Live in one of the older houses around St Leonard's Church? Expect the survey to look closely at heat loss and at the building’s planning status.

Aftercare tips
Simple habits make a real difference. We recommend:
- Keep radiators clear
- Know the servicing conditions in your warranty
- Leave space around the outdoor unit
Where we applied for a Boiler Upgrade Scheme grant, we keep you informed through the process, as the installer applies for it.
Keep the outdoor unit clear of leaves, plants and stored items. Airflow is what it runs on, so keep it clear all year.

Fixed-price quotes for air source heat pumps in Heston
Before we fix a price, we need to know a few things. We check:
- The electrical supply and whether a new circuit is needed
- Whether it’s a simple split or a larger system
- What we find on the survey or diagnosis
One room or a whole building, the quote is built the same way: the work involved, the access and the equipment. The price is fixed before we start, and the quote sets out the VAT.
Helping us quote
Simple jobs can often be priced from pictures and some basics. Send what you can of the following:
- The rating plate or label on any existing unit
- The address and the type of property
- A photo of the consumer unit with the cover closed
Every quote starts with a look at the job, either on a site survey or, for simple jobs, from your pictures and details. Then you get a fixed price so you know the cost before we begin.
The process
Every visit follows the same order: check the plan with you, put the dust sheets down, carry out the job, test what we’ve done and talk you through it. The visit itself 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. Photos of the room and where the outdoor unit could go let us plan most of a visit to Heston in advance.
- First, a chat about the property and your goals for the heating.
- The survey checks heat loss, emitters, hot water and the outdoor unit position.
- You get our view on the right type for the house, and on whether the Boiler Upgrade Scheme applies.
- Installation follows on the agreed dates.
- The job ends with commissioning, the MCS certificate and a walk through the controls.
How to prepare
- Make sure we can reach the consumer unit or fuse board
- Mention any managing agent or landlord rules we need to follow
- Clear the space around the indoor unit, or where it will go
Getting a price
The quickest way to a quote is to send photos: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Add the address and what you’d like done, and simple jobs can often be priced without a visit.
