System by system
Air-to-air heat pumps
Air-to-air heat pumps are now covered by permitted development rules in England, subject to conditions. A unit used solely for cooling isn’t covered, so check with the council.
VAT on heat pumps
Heat pumps in homes carry 0% VAT until 31 March 2027, and 5% after that, under HMRC Notice 708/6. Businesses pay the standard rate.
Air source heat pumps for homes and businesses in Spellbrook
Installing an air source heat pump in a home is zero-rated for VAT until 31 March 2027, then 5%. That follows HMRC Notice 708/6, and it does not apply to businesses. For air-to-air systems, we confirm the VAT on your quote. Please treat this as general information rather than tax advice. The work covers homes heated by oil, LPG or gas, air-to-air heat pumps and radiator systems, and common reasons people get in touch are working out where a cylinder could go and wanting to stop using oil, LPG or gas for heating.
Space for an outdoor unit is rarely an issue near Spellbrook, so the design comes down to heat loss, radiators and hot water.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, ready for the next service or a warranty query.

For landlords and property managers
Whether it’s one property or many, you get the same standard: a look at the job first, a fixed-price quote, work booked with the occupier and written records afterwards.
If you look after several properties, we can plan visits across the portfolio and price them together. Every address has its own paperwork, so the files stay tidy.
Spellbrook: your questions answered
Will you come out to Spellbrook?
Yes, and the size of the place makes no difference to how we work. Visits to smaller places are planned so the engineer arrives with what the job needs.
Is the heat pump grant available in Spellbrook?
Spellbrook is in England, where the Boiler Upgrade Scheme runs. 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. We hold MCS certification, so the application is ours to make for you.
Do you look at the job first?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the job needs and how to do it, and the quote is based on that.
Which accreditations do you hold?
As the law requires for refrigerant work, we are an F-Gas certified company. We’re also NICEIC approved, MCS certified for heat pumps and Checkatrade members.
Will my radiators work with a heat pump?
The heat loss survey answers that, room by room. Where a radiator is already large enough, it stays, and any that need upsizing are set out in the quote.
Can you come out in an emergency?
Yes, any time. For anything urgent, such as a system failing in a server room or water leaking from a unit, ring our 24/7 line and we’ll agree what happens next.
Will I get records for the system?
Yes, always. 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.
What we do, step by step
We book the visit for a day and time that suit you, and we let you know if plans need to move. When we arrive, we check the job against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. From there, the work takes a few days on site, depending on the cylinder, the radiators and the pipework involved. Pictures of the space and where the outdoor unit could go let us plan the work in Spellbrook.
- First we talk through the property and the current system.
- A heat loss survey is carried out, room by room.
- The design covers the heat pump, emitters, hot water and outdoor unit.
- You get a fixed price, with any grant and the VAT set out.
- Installation, commissioning and MCS registration complete the job.
How to prepare
- Mention any roof access, ladders or high-level work
- Clear the space around the indoor unit, or where it will go
- Find the manual or the paperwork for the system, if you have it
Ask for a quote
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, phone us on 07833 053749 or fill in the contact form.
Advice
What affects the quote in Spellbrook
Before we fix a price, we need to know a few things. We look at:
- How many units are involved
- Access, including height, roofs and ladders
- What state the existing equipment is in
Leaving a fault or an overdue service rarely makes the work cheaper. Faults and wear in a system tend to grow, and a struggling system uses more electricity to do less. If you’re unsure, call us on 07833 053749 or fill in the contact form and we’ll give you an honest view and a fixed price.
What to send for a quote
When you call or email, these details help:
- Where the outdoor unit is, or where you’d like it
- Photos showing the indoor unit and the space around it
- Any previous service or F-Gas records
Getting a quote is straightforward. 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.
Homes in Spellbrook and heat pumps
On the National Heritage List, around 9 entries fall within 0.5 miles of the middle of Spellbrook; Hallingbury Mill (grade II*) is one. Where a home is affected, the outdoor unit position is settled with the local planning authority (normally East Hertfordshire council) before the heat pump design is finished. About 76% of households live in detached or semi-detached houses, according to Census 2021 figures. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
Older homes near Church of St Mary the Virgin may need extra checks for planning and heat loss before a heat pump is designed. If your home is listed, like Much Hadham Palace about 3.8 miles north-west, listed building consent comes before any heat pump work.
