Air source heat pumps in South Darenth, done properly
Air-to-air heat pumps can qualify for a £2,500 Boiler Upgrade Scheme grant, but only in some cases. It has to replace the fossil-fuel heating, cover the whole heating demand, be fitted by an MCS certified installer and be in a home; adding it alongside a boiler does not qualify. The work covers hot water cylinders, air-to-water heat pumps and underfloor heating, and the jobs we see most are planning and permitted development questions and not knowing whether a grant applies.
If your home in or near South Darenth is heated by oil, LPG or electric heaters with no mains gas, the Boiler Upgrade Scheme adds an extra £1,500 until March 2027 for an air source or ground source heat pump.
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. File it with the manual, because it helps with any later warranty question.

Homes in South Darenth and heat pumps
Valuation Office Agency council tax records date about 50% of homes in and around South Darenth to the post-war years, 1945 to 1972, and about 60% of households live in detached or semi-detached houses, according to the 2021 Census. 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.
With Lullingstone Castle about 3.9 miles south-west, it’s worth asking whether your own home is listed before planning a heat pump.

Landlords, agents and facilities managers
Keeping records across a portfolio is half the battle. Each visit produces a dated record, with F-Gas records wherever refrigerant work is involved, ready for a tenant, a buyer or an inspection.
We regularly work with managing agents. Send the address, what’s needed and how access works, and we’ll send a fixed-price quote.
The process
Protection comes first: sheets over the floor and any furniture nearby and nothing is moved without asking you. Then the electrics are made safe and the work begins. The work on site 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, and we tidy up before we leave. For a village like South Darenth, tell us about narrow lanes, gates and parking when you book.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- We survey the home room by room for heat loss, and check the emitters, hot water and outdoor unit position.
- You get a fixed-price quote, with any grant you are eligible for and the VAT explained.
- Fitting day: the outdoor unit is placed, the indoor side connected and the controls set up.
- We commission the heat pump, complete the MCS paperwork and talk you through the controls.
Before we arrive
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Keep pets out of the rooms we’re working in

Advice
What affects the cost of air source heat pumps
The quote reflects the job in front of us. We take into account:
- The equipment or parts the job needs
- A single visit or a regular plan
- What we find on the survey or diagnosis
Whatever the property, the quote works the same way: the equipment, the access, the work involved and the time it takes. Call for a fixed-price quote and we will go through it with you.
What we need to know
To help us quote quickly, send us:
- A few photos of the room and the wall the unit is on, or will go on
- Any previous service or F-Gas records
- The rating plate or label on any existing unit
Here’s what helps us quote: where the property is and what kind of building it is, pictures of the rooms or units, the brand and model of anything already fitted and anything you’ve noticed, such as an error code or a noise. Once you have those, ring us on 07833 053749 or email us.

Your questions about air source heat pumps in South Darenth
Can I fit a heat pump in South Darenth without planning permission?
There’s no single answer: the building and the outdoor unit position decide it. Central South Darenth sits inside a conservation area. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights do not reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask the planning department at Sevenoaks council, usually the authority for South Darenth.
Does the Boiler Upgrade Scheme cover homes in South Darenth?
Yes, the scheme covers homes in England, including South Darenth, 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. We hold MCS certification, so the application is ours to make for you.
Can I do any of the installation myself?
Not the refrigerant work. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.
Who is responsible for leak checks?
The operator of the equipment, working with qualified engineers. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We can tell you which band your system falls into.
Do I need to service the system to keep the warranty?
For some brands, yes. Send us the make and model and we will tell you what the manufacturer expects, and book the service at the interval they recommend.
Will I get records for the system?
Yes. Every visit is written up, including F-Gas records for any refrigerant work. Keep them with the manual and the warranty documents.
What does an air-to-water heat pump cost?
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes) before the grant. Eligible homes in England and Wales can get £7,500 through the Boiler Upgrade Scheme, and we confirm eligibility before you commit.

“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
