Why deal with it now?
If the emitters cannot give out enough heat, some rooms will not get warm enough. The survey picks this up before installation. Small faults tend to grow, so it’s worth dealing with them early.
The pipe route, the height of the units and how we reach them can all change the price. We take each of them into account, and the price is fixed before any work starts.

Air source heat pumps for homes and businesses in Gustard Wood
Until 31 March 2027, a heat pump installed in residential accommodation carries 0% VAT, with 5% from 1 April 2027. 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. Please treat this as general information rather than tax advice. If the problem is comparing heat pump types and checking whether planning permission is needed, we can sort it out.
For a home around Gustard Wood that is off mains gas and heated by oil or LPG, an extra £1,500 is available through the Boiler Upgrade Scheme until March 2027.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. Keep the records with the manual and the warranty documents, as a manufacturer or a future engineer may ask to see them.

Towns and villages near Gustard Wood
What else we do in Gustard Wood
Your questions about air source heat pumps in Gustard Wood
Will you come out to Gustard Wood?
We do. Villages and hamlets get the same service as the bigger towns. A few photos and the postcode are enough to get things started.
Do I need planning permission for a heat pump in Gustard Wood?
There’s no single answer: the building and the outdoor unit position decide it. The centre of Gustard Wood is in the Gustard Wood Conservation Area. A heat pump on a house can be permitted development if it meets the conditions, including the MCS noise check, but not within the grounds of a listed building, and in a conservation area the outdoor unit can’t face a road. Where needed, we check with the planning department at St Albans City council, usually the authority for Gustard Wood.
Can we book visits on a schedule?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Every visit is recorded, with F-Gas records where refrigerant work is involved.
What warranty do I get?
The manufacturer’s warranty, on the manufacturer’s terms. Each brand sets its own conditions and periods, so we explain them on your quote.
Can I do any of the installation myself?
No, not the refrigerant side. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new electrical circuit is notifiable building work unless a registered competent person does it.
Am I eligible for a heat pump grant?
We check the scheme rules for your property before you go ahead. The installer applies for the grant, so we handle the application if you are eligible.
Can I get a grant for an air-to-air heat pump?
There is a £2,500 grant for air-to-air, but only under strict conditions. It has to replace the fossil-fuel heating, meet the full heating demand, be fitted by an MCS certified installer, and be in a home.
What the work involves, system by system
VAT on heat pumps
Installing an air source heat pump in a home is zero-rated until 31 March 2027, then 5%, under HMRC Notice 708/6. Businesses pay the standard rate.
Hot water cylinders
Cylinder size is based on your household’s needs.
Looking after it afterwards
Here’s the after-treatment advice, short and simple:
- Don’t block radiators or indoor units with furniture
- Check what your manufacturer’s warranty asks of you
- File the MCS certificate safely
Equipment warranties come from the manufacturer. We explain the terms for your brand, including any servicing conditions.
Leave space around the outdoor unit. It needs good airflow to collect heat from outside so keep it unobstructed.
What happens on the day
We keep the work area tidy as we go, with sheets down and mess cleared as we go. Any holes, fixings or cable routes are agreed with you before we drill. On site, it takes a few days for most air-to-water installations, with air-to-air systems often quicker. Work in Gustard Wood is booked in advance at a time that suits you.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- On the visit we calculate what every room loses on a cold day, then check the radiators, room for a cylinder and outdoor unit options.
- We send a fixed-price quote that shows the equipment, the grant position and the VAT.
- The outdoor unit, the indoor equipment and the controls are installed and connected.
- Commissioning, MCS certification and a handover of the controls finish the job.
Getting ready for the visit
- Keep pets out of the rooms we are working in
- Arrange for someone to be there to let us in
- Have the make and model of any existing unit to hand
