Air source heat pumps for homes and businesses in Darenth
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, so an add-on next to a boiler is not eligible. The work covers homes heated by oil, LPG or gas, underfloor heating and hot water cylinders, and common reasons people get in touch are deciding which kind of heat pump suits the home and moving away from fossil-fuel heating.
If your home in or near 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, on top of the £7,500.
The records are your system’s health record: what was fitted or found, what was done and when. It makes the next visit quicker and any warranty question simpler and it’s worth keeping safe.

Looking after your system
Aftercare is straightforward, and it helps at the next service:
- Keep the outdoor unit clear all year
- Let the heat pump run steadily, as set up at handover
- Store the MCS certificate and warranty documents together
In cold, damp weather the outdoor unit runs a defrost cycle from time to time. You might see steam or hear the unit change note and it’s part of how the system works.
Leave space around the outdoor unit. It needs good airflow to collect heat from outside, so keep it clear all year.
What we do, step by step
There’s very little for you to do on the day. Someone needs to let us in and show us the units, or where they’re going, and we take it from there. At the end, we tidy up and run through the work with you. Seeing the property in pictures first means the trip to Darenth can be planned properly.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- The survey measures heat loss room by room and looks at radiators, hot water and the best spot for the outdoor unit.
- The price comes back fixed and in writing, with the grant and VAT shown line by line.
- The outdoor unit, the indoor equipment and the controls are installed and connected.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
Preparing for the visit
- Find the manual or the paperwork for the system, if you have it
- Clear a path to the units and the space around them
- Keep pets out of the rooms we are working in
How to get a quote
Photos are the fastest route to a quote: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Add the address and what you’d like done, and simple jobs can often be priced without a visit.

Common problems we fix in Darenth
When a home is being extended or renovated, it’s a good moment to look at heat pumps. Pipework, radiators and space for a cylinder are easier to plan while work is going on.
Any of these is worth a proper look:
- Checking whether planning permission is needed
- Working out whether radiators need upsizing
- Deciding which kind of heat pump suits the home
If your home is one of the older properties near Church of St Margaret of Antioch, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.
Before booking anyone
- Whether you get F-Gas records where refrigerant is involved
- How extra work would be agreed if they find something unexpected
- Whether the quote shows VAT clearly
Air source heat pumps around Darenth
At about 16 miles from central London, Darenth sits inside the area we cover across London and the South East. Valuation Office Agency council tax records date about 50% of homes in the Darenth area to the post-war years, 1945 to 1972, and Census 2021 figures found about 60% of households in detached or semi-detached houses. Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period. Detached and semi-detached houses usually have room for the outdoor unit and a cylinder.
Hall Place and Gardens lies about 4.6 miles north-west. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions.

Darenth: your questions answered
Can you do air source heat pumps in Darenth?
Yes, Darenth is within the area we cover. Tell us a little about the job and we will take it from there.
Is Darenth within the area you cover?
We do. Villages and hamlets get the same service as the bigger towns. A few pictures and the postcode are enough to get things started.
What accreditations do you have?
As the law requires for refrigerant work, we’re an F-Gas certified company. We’re also NICEIC approved, MCS certified for heat pumps and Checkatrade members.
Is there a survey before the work?
Yes. Photos often do the job for simple work, while bigger systems and repairs that need testing get a visit.
Will you make a mess?
Floors and furniture near the work are covered with dust sheets before we start, and we tidy up as we go. Before we leave, we clear up and run through the work with you.
Will you work on another installer’s system?
Yes. We work on systems fitted by other installers as well as our own from all the leading brands. Tell us the make and model and send any paperwork you have.
Can I get a grant for an air-to-air heat pump?
It can, as long as the system takes over the heating completely. The £2,500 applies when it replaces the fossil-fuel heating, covers the full heating demand, is fitted by an MCS certified installer and serves a home. Fitted alongside a boiler, it will not qualify.

“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
