When to call us in Mill Hill
Extensions, renovations and loft conversions are a natural time to rethink the heating. Pipework, radiators and space for a cylinder are easier to plan while work is going on.
Customers typically contact us when they notice something like this:
- Checking emitters for a heat pump
- Comparing heat pump types
- Not knowing whether a grant applies
Heath Hall lies about 4 miles south-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
- Which brand and model they’re proposing, and why
- Whether extra work needs your approval first
- Whether a new circuit is included and who certifies it
Air source heat pumps in Mill Hill, done properly
We install air source heat pumps in Mill Hill and across Greater London, and we are MCS certified. Air-to-water systems feed your radiators or underfloor heating and hot water cylinder, while air-to-air systems heat rooms directly through indoor units and can cool them too. We help you work out which suits your home. The work covers radiator systems, hot water cylinders and air-to-air heat pumps, and the jobs we see most are checking whether planning permission is needed and working out whether radiators need upsizing.
In a flat in Mill Hill, the lease and the freeholder typically decide where a heat pump can go. Permitted development limits are different for flats, so we check the position before we design.
Any work on the refrigerant circuit is recorded: the work carried out, the refrigerant involved and the quantities. Keep the records with the manual and the warranty documents, as a manufacturer or a future engineer may ask to see them.

How it works
Every visit follows the same order: agree the plan on site, protect the area, carry out the job, check the system and explain it all to you. The visit itself takes a few days for most air-to-water installations, with air-to-air systems often quicker. In a London area like Mill Hill, parking and access are worth sorting out before the day.
- First we talk through the property and the current system.
- We measure heat loss for every room.
- From those figures we size the heat pump and decide on radiators, cylinder and outdoor position.
- Cost, grant and VAT appear on one fixed-price quote.
- Installation, commissioning and MCS registration complete the job.
Before we arrive
- Clear access to the fuse board
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Find the manual or the paperwork for the system, if you have it
How to get a quote
Every quote starts with a look at the job, either on a site survey or, for simple jobs, from your photos and details. Then you get a fixed price so you know the cost before we begin.

Questions from Mill Hill
Can I get the Boiler Upgrade Scheme grant in Mill Hill?
Yes, if the home and the heat pump meet the scheme’s rules: Mill Hill is in England, where it applies. 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. We hold MCS certification, so the application is ours to make for you.
Is a heat pump in Mill Hill permitted development?
The answer turns on the property and where the outdoor unit would sit. The Mill Hill Conservation Area takes in the middle of Mill Hill. Heat pumps on houses are often permitted development, but listed buildings need consent and conservation areas restrict outdoor units facing a road. Where it’s needed, we check with the local planning authority (for Mill Hill, usually Barnet council).
Can you come out in an emergency?
Yes, 24/7. Call the emergency line and tell us the make, the symptoms and any error code, and we will talk you through the next steps.
Which manufacturers do you install and repair?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For a new system, we suggest the make and model that suit the property and tell you why.
Will my radiators work with a heat pump?
We find out during the survey. Rooms where the radiator is big enough stay as they are and any changes are in the quote.
Do you work on commercial properties?
Yes. Homeowners, landlords, agents and businesses all book us across London and the South East. Let us know who the records should go to.
What’s the price of a heat pump installation?
Air-to-water systems are £8,000–£16,000 (0% VAT on homes), before any grant. The final price depends on the heat loss survey, the radiators and the cylinder, and you get a fixed-price quote.
What you can do yourself, and what needs us
Before you call us about a fault, a few checks can save a visit: check the mode, the set temperature, the remote’s batteries and the breaker. If a breaker trips again after you reset it, leave it off and phone us on 07833 053749, or email if that’s easier.
Do not move, re-route or disconnect units or pipework yourself. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrical side needs a competent person. Ask us to quote for a move instead.
What a heat pump looks like in Mill Hill
About 43% of homes in and around Mill Hill were built between the wars, according to the Valuation Office Agency’s council tax figures. For homes of that age, the survey checks the insulation, the radiators and the hot water setup. For a London home, the outdoor unit position and the MCS noise check need careful planning.
Period properties close to St Paul's Church can suit a heat pump, though insulation and any heritage protection are checked first.
