After we have gone
Every system needs looking after, and most of it is easy. A few tips:
- Ask about the grant before you commit
- Leave space around the outdoor unit
- Know the servicing conditions in your warranty
If you were eligible for a grant, we handle the application and keep you updated since the grant goes through the installer.
Keep the outdoor unit clear of leaves, plants and stored items. Airflow is what it runs on, so keep it clear all year.
About our air source heat pumps in Belsize
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes), before the grant. The Boiler Upgrade Scheme can provide £7,500 towards an eligible air-to-water system in England and Wales and the installer makes the application. Eligibility depends on the property, so we confirm it before anything is agreed. Typical jobs include a boiler that’s getting old and working out where a cylinder could go, across radiator systems, homes heated by oil, LPG or gas and air-to-water heat pumps.
Older and listed homes in villages like Belsize need extra care, and permitted development doesn’t cover listed buildings, so consent comes first.
Equipment warranty comes from the manufacturer, on its own terms, and we set them out on your quote. Terms differ from brand to brand, so we go through them with you rather than leave you to find the small print.

The process
Refrigerant work is done by qualified engineers working for an F-Gas certified company, and electrical work is done by us as NICEIC approved contractors. So on the day, you don’t need a separate electrician for the electrical side. On site, it takes a few days on site, depending on the cylinder, the radiators and the pipework involved. Seeing the property in pictures first means the trip to Belsize can be planned properly.
- First we find out about the property, the heating you have now and what you’re hoping for.
- 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.
- We send a fixed-price quote that shows the equipment, the grant position and the VAT.
- The outdoor unit, the indoor equipment and the controls are installed and connected.
- The system is commissioned and registered under MCS, and we show you how to use it.
Before we arrive
- Tell us about any building rules, permits or sign-in
- Unlock any gate, garage or side passage we need
- Tell us about parking and loading

Pricing air source heat pumps in Belsize
The diagnosis comes before the price. We look at:
- How many units are involved
- What electrical work the job needs
- Whether it’s a one-off job or part of a maintenance contract
Typical ranges are on our prices page, but each job is priced on what it involves. Call for a fixed-price quote, and we will explain what it covers.
What we need to know
What to send for a quote:
- Where the property is and what kind of building it is
- A close-up of the unit’s label showing the model number
- The outdoor side of the property, including any roof or flat area
Some jobs can be priced from photos, while others need a survey. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, you get a fixed price before any work is booked.
Air source heat pumps around Belsize
Belsize’s centre is no more than about a third of a mile from the Chipperfield Conservation Area. Draw a one-mile circle round the middle of Belsize and it takes in 2 conservation areas. On the National Heritage List, around 21 entries fall within 0.5 miles of the middle of Belsize; Belsize House (grade II) is one. That affects heat pumps: listed buildings need consent, and conservation areas limit where the outdoor unit can go under permitted development. Where needed, we check with the planning team at Three Rivers council, which normally handles Belsize. About 68% of households live in detached or semi-detached houses, according to Census 2021 figures. Detached and semi-detached houses normally have room for the outdoor unit and a cylinder.
Historic houses such as Chenies Manor House, about 2 miles south-west, are a reminder that listed homes need consent before a heat pump goes in. Period properties close to Church of St Paul can suit a heat pump, though insulation and any heritage protection are checked first.

Questions from Belsize
Can I get the Boiler Upgrade Scheme grant in Belsize?
Yes, if the home and the heat pump meet the scheme’s rules: Belsize is in England, where it applies. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. You do not apply yourself: the MCS certified installer does, which is us.
Do you cover smaller places like Belsize?
Yes, smaller places are covered as well as towns. A few pictures and the postcode are enough to get things started.
When will I hear back?
On the same working day you contact us. Then we agree a date that works for you, and you get a fixed price before any work goes ahead.
Do you work on commercial properties?
Yes. From a single let flat to offices, shops and public buildings, the approach is the same: survey or diagnosis, a fixed price and proper paperwork.
What accreditations do you have?
We’re an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We’re members of Checkatrade too.
Which brands do you work with?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For new systems, we recommend a brand and model to suit the job and explain why.
Can you look at a system you didn’t fit?
Yes. We start with a proper look and tell you honestly what we find, including anything about the original installation that needs putting right. Any work is priced before it goes ahead.
