Air source heat pumps in Gravesend, done properly
Until 31 March 2027, a heat pump installed in residential accommodation carries 0% VAT, with 5% from 1 April 2027. That follows HMRC Notice 708/6, and it doesn’t apply to businesses, and for air-to-air systems we confirm the VAT on your quote. This is general information, not tax advice. If the problem is questions about listed buildings or conservation areas and questions about where the outdoor unit can go, we can sort it out.
Homes around Gravesend normally have room outside for a heat pump, so the design focuses on heat loss and radiators.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We’ll explain how the manufacturer’s terms are likely to apply before any chargeable work goes ahead.

Fixed-price quotes for air source heat pumps in Gravesend
A fixed price needs a few facts first. We check:
- Whether it’s a simple split or a larger system
- How far the pipework has to run, and where
- Whether it’s a one-off job or part of a maintenance contract
What you pay depends on the system and the number of rooms or units, the access and the parts and time the job needs. We give you a fixed price before we start, so there are no surprises.
What to send for a quote
When you call or email, these details help:
- The paperwork from the last service, if you have it
- The make and model of the system, from the label
- The fuse board and where it is in the property
VAT is set out clearly on every quote, 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. To get one, call us on 07833 053749 or use the quote form.
What we do, step by step
Our engineers bring the tools, gauges and access equipment the job needs. You only need to give us clear access to the units, or their planned positions, and to the fuse board. The visit takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. A note on how to find the property and where to park makes a visit to Gravesend easier.
- 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’re eligible for and the VAT explained.
- We fit the outdoor unit and connect it to the heating, hot water and controls.
- Commissioning, MCS certification and a handover of the controls finish the job.
Getting ready for the visit
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Keep pets and children away from the work area
- Have the make and model of any existing unit to hand

Common problems we fix in Gravesend
The Boiler Upgrade Scheme has made people ask whether their home could qualify. Eligibility depends on the property, the system and the scheme rules and we confirm it before you go ahead.
What we’re most often called about:
- An oil, LPG or gas boiler near the end of its life
- Working out whether radiators need upsizing
- Comparing heat pump types
Live in one of the older houses around Church of St Mary? Expect the survey to look closely at heat loss and at the building’s planning status.
Before booking anyone
- If the quote is based on a survey, photos or a diagnosis
- If the figure could change on the day
- Whether the electrical work is done by a registered contractor, such as NICEIC approved

At lower water temperatures, radiators give out less heat, and the survey checks each one.
Outdoor unit position and planning
Flats and blocks of flats have different limits, and Article 4 directions can remove rights. Listed buildings also need separate consent and we check what applies to you.
Air source heat pumps in Gravesend: the local picture
The Valuation Office Agency’s council tax figures show about 31% of homes across Gravesend and its surrounding area were built in 2000 or later, and about 75% of households live in detached or semi-detached houses, according to the 2021 Census. Better insulated, newer homes are often a good match for a heat pump. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
If your home is listed, like Much Hadham Palace about 3.6 miles south, listed building consent comes before any heat pump work.

Questions from Gravesend
Is a heat pump in Gravesend permitted development?
There’s no single answer: the building and the outdoor unit position decide it. Central Gravesend is a short walk from the Patmore Heath 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 the local planning authority (for Gravesend, typically East Hertfordshire council).
Is the heat pump grant available in Gravesend?
Gravesend is in England, where the Boiler Upgrade Scheme runs. The amount depends on the type of heat pump, and the survey confirms which applies. The installer applies, and we’re MCS certified.
Do you offer emergency call-outs?
Yes, any time. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we’ll agree what happens next.
Do you provide F-Gas records?
Yes. Every visit is written up, including F-Gas records for any refrigerant work. File them with the system’s paperwork.
Is Gravesend in your area?
Yes. We work in Gravesend and across Hertfordshire, within the London and South East area we cover. For a fixed-price quote, call 07833 053749 or fill in the contact form.
Why use an F-Gas certified company?
Certification shows a business is approved to work on systems that hold F gas refrigerant. That isn’t optional: it’s required by law, and AirCon Doctor is certified.
Do you protect the property while you work?
We start with protection: dust sheets over floors and anything close to the work. Holes and fixings are agreed with you, and we clean up afterwards when we finish.
From one of our customers
“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.”
