Questions from Otford
Will a heat pump in Otford need planning permission?
The answer turns on the property and where the outdoor unit would sit. The centre of Otford is in a conservation area. 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 Sevenoaks council, which is typically the planning authority for Otford.
Is the heat pump grant available in Otford?
Yes, if the home and the heat pump meet the scheme’s rules: Otford 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.
What accreditations do you have?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, plus Checkatrade membership. Engineers who handle refrigerant hold their own F-gas qualifications as well.
Which brands do you work with?
We work with the leading brands, from Mitsubishi Electric, Daikin and Fujitsu to Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we will take it from there.
Do you provide F-Gas records?
Yes. Each visit is written up, and any work on the refrigerant circuit goes in the F-Gas records. File them with the system’s paperwork.
How much does an air source heat pump cost?
Air-to-water work is in the £8,000–£16,000 range (0% VAT on homes), with any grant still to come off. Where you land depends on the size of heat pump, any radiators that need changing and the hot water cylinder, and air-to-air systems are priced after a survey.
When will I hear back?
The same working day. Then we agree a date that works for you, with a fixed price before work starts.
Air source heat pumps in Otford, done properly
A heat pump takes heat from the outside air and moves it into your home with electricity running the compressor and fans. It works on the same principle as air conditioning, run the other way, and air-to-air heat pumps are sometimes simply called air conditioning. If you are dealing with an oil, LPG or gas boiler near the end of its life and checking eligibility for a heat pump grant, we can help.
Cottages and older homes near Otford can lose heat faster, which a heat loss calculation will show. Sometimes insulating first makes more sense.
Think of the paperwork as the system’s health record: a dated account of the work and the readings we took. It makes the next visit quicker and any warranty question simpler and it’s worth keeping safe.

How the visit works
Everything the job needs comes with us, from tools and test equipment to ladders and dust sheets. You only need to give us clear access to the units, or their planned positions, and to the fuse board. On site, the work takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. Tell us about any gates or steps at your property near Otford when you book.
- It begins with your house and the heating it relies on now.
- Every room’s heat loss is worked out on site.
- We design the system, check the radiators and cylinder and look at the outdoor unit position.
- A fixed-price quote explains the cost, the grant position and the VAT.
- Then it’s fitted, commissioned and registered with MCS.
Getting ready for the visit
- Name a contact who can meet us at the agreed time
- Let us know where we can park and unload
- Plan for pets to be kept clear during the visit
Ask for a quote
Every quote shows the VAT clearly, and the rate that applies to your job is stated. VAT can differ between homes and businesses and between kinds of work, so we confirm it in writing rather than guess. For a fixed-price quote, phone us on 07833 053749 or send an email.

What air conditioning won’t do
We’d rather tell you now than sell you work that won’t help, so these are the things it will not cover:
- Gas boiler work, such as disconnecting the old boiler, which needs a Gas Safe registered engineer
- Tax rulings, which only HMRC can give
- Insulation work, such as loft or cavity wall insulation
Not sure which it is? You can call 07833 053749, or email if that’s easier and we’ll tell you honestly before you book.
Parts of the system we cover

Safe owner checks
There are a few things you can safely do yourself: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Opening up the units, the electrics and the refrigerant circuit are a job for us.
Keep a note of anything odd: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It helps us diagnose quickly, and a photo of the display helps even more.
What a heat pump looks like in Otford
VOA council tax data date about 43% of homes in the Otford area to the post-war years, 1945 to 1972, and Census 2021 figures found about 82% 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. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
If your home is near Otford station and heated by a gas boiler, an air-to-water heat pump can replace it where the survey shows it suits. Historic houses such as Knole House, about 3.2 miles south, are a reminder that listed homes need consent before a heat pump goes in.

Fixed-price quotes for air source heat pumps in Otford
Every job gets its own quote. This is what makes a difference:
- The number of rooms, units or zones
- How far the pipework has to run, and where
- The equipment or parts the job needs
Homes, offices, shops and public buildings are all priced the same way: the equipment, the access, the work involved and the time it takes. Ask for a fixed-price quote and we’ll explain each part.
Before you get in touch
Good pictures often save a visit. The most useful are:
- The address and the type of property
- The rating plate or label on any existing unit
- Any error code or flashing light on the display
Photos are enough for some jobs; others need a visit first. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, you get a fixed price before any work is booked.
