How we handle air source heat pumps in Tower Hill
Installing an air source heat pump in a home is zero-rated for VAT until 31 March 2027, then 5%. This is HMRC’s energy-saving materials relief, which applies to homes rather than businesses. For air-to-air systems, we confirm the VAT on your quote. This is general information, not tax advice. The work covers hot water cylinders, air-to-water heat pumps and radiator systems, and common reasons people get in touch are radiators that may be too small for a heat pump and not knowing whether a grant applies.
Older and listed homes in villages like Tower Hill need extra care, and permitted development doesn’t cover listed buildings, so we check consent first.
Refrigerant work is written up in the F-Gas records: what was done, the refrigerant type and any amount added or recovered. Keep the records with the manual and the warranty documents, ready for the next service or a warranty query.

Homes in Tower Hill and heat pumps
About 68% of households live in detached or semi-detached houses, according to the last census (2021). Houses normally have space for an outdoor unit and a hot water cylinder.
If your home is one of the older properties near Church of St Paul, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen. With Chenies Manor House about 2.8 miles south-west, it’s worth asking whether your own home is listed before planning a heat pump.
Tower Hill is about 3 miles south-west of Hemel Hempstead, in Hertfordshire. Tower Hill gets the same approach as every job we take on: a look at the job first, a fixed-price quote and written records at the end. Our area takes in 381 places across Hertfordshire, from busy centres to quieter spots. The nearest of our city pages is London, around 23 miles from Tower Hill.

Local landmarks in Tower Hill
Around Tower Hill, our work takes us to homes and businesses near The Boot Public House and the streets around them.

Open spaces near Tower Hill include Sarratt Bottom nature reserve.
Owner checks or an engineer?
Owners can handle the everyday basics: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Leave the units and pipework where they are. 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.
Tower Hill questions
Is the heat pump grant available in Tower Hill?
Tower Hill is covered, as the scheme runs across England and Wales. 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. The installer applies, and we’re MCS certified.
Is planning permission needed for a heat pump in Tower Hill?
It comes down to the building and the spot chosen for the outdoor unit. Central Tower Hill is a short walk from the Chipperfield 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 planning department at Dacorum council, usually the authority for Tower Hill.
Can we book visits on a schedule?
Yes. Send details of the systems and how they’re used, and we will suggest a schedule with a fixed price. Leak checks required by the F-gas rules can be built in for larger systems.
Do I get paperwork after the visit?
Yes, on every job. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, while repairs and services get a written note of what was found and done.
Is the equipment covered by a warranty?
Warranty comes from the manufacturer and depends on the brand and product. Daikin, for example, gives a standard 2 years on split air conditioning, and we explain the terms for whichever brand you choose.
Who is responsible for leak checks?
Responsibility is shared between the operator, normally whoever owns or controls the equipment, and the service technicians. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Do I need new radiators for a heat pump?
That depends on the room’s heat loss and the radiator’s size. The survey compares each radiator with the room’s needs, so the quote covers any changes.
What affects the cost of air source heat pumps
Every job gets its own quote. These are the things that affect it:
- The distance and route between the indoor and outdoor units
- What electrical work the job needs
- What state the existing equipment is in
The cost depends on the system and the number of rooms or units, the access and what the work involves. You get a fixed price before any work starts, so there are no surprises.
What to send for a quote
A few details help us quote accurately. With your enquiry, please include:
- The rating plate or label on any existing unit
- A photo of the consumer unit with the cover closed
- The outdoor side of the property, including any roof or flat area
Quotes do not take long. Call or email with a few details and we will come back to you the same working day. If we need to see the property first, we book a survey at a time that works for you.
How the visit works
Protection comes first: sheets over the floor and any furniture nearby, and we ask before moving anything. After that, anything electrical is made safe and we start. It 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. Photos of the existing unit help with repairs and servicing in Tower Hill.
- First, a chat about the property and your goals for the heating.
- We survey for heat loss and look at radiators, cylinder space and outdoor unit options.
- We explain which type of heat pump suits the home and whether a grant could apply.
- We install the heat pump and connect it up.
- We commission it, complete the MCS certificate and show you how to use it.
Getting ready for the visit
- Clear access to the fuse board
- Mention any managing agent or landlord rules we need to follow
- Unlock any gate, garage or side passage we need
Getting a quote
Some jobs can be priced from photos, while others need a survey. 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.

Aftercare tips
To keep the system working properly:
- Read the manufacturer’s warranty terms for your brand
- File the MCS certificate safely
- Clear leaves and debris from the outdoor unit
After commissioning, the installation is registered under MCS and you receive the certificate. Keep it with the manufacturer’s paperwork, as you may need it later.
Let the heat pump run steadily rather than switching it on and off, using the settings agreed at handover.
