Air source heat pumps in Stevenage
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, and for air-to-air systems we confirm the VAT on your quote. Please treat this as general information rather than tax advice. If you’re dealing with planning and permitted development questions and replacing a combi boiler with a heat pump, we can help.
In Stevenage, some homes suit an air-to-air system instead, which heats and cools through indoor units. To get the £2,500 air-to-air grant, it has to replace the existing fossil-fuel heating and heat the whole home.
Nothing is signed off by word of mouth: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. Keep it with the system’s paperwork, because it helps with any later warranty question.

Homes in Stevenage and heat pumps
About 29 miles out from central London, Stevenage is part of the South East area we work across. About 71% of homes in and around Stevenage date from 1945 to 1972, according to the Valuation Office Agency’s council tax figures, and the last census (2021) found about 50% of households in terraced houses. For homes of that age, the survey checks the insulation, the radiators and the hot water setup. In a terrace, the outdoor unit position and the MCS noise check need particular care.
Historic houses such as Aston Bury, about 2.5 miles south-east, are a reminder that listed homes need consent before a heat pump goes in. Older homes near St Hugh & St John may need extra checks for planning and heat loss before a heat pump is designed.

What affects the cost of air source heat pumps
Some jobs are bigger than they look, and some smaller. The main factors:
- Whether it’s a one-off job or part of a maintenance contract
- The type of system, from a single split to a larger system
- The pipe route between the units
The pipe route, the height of the units and how we reach them all affect the cost. We take each of them into account, and the price is fixed before work begins.
Before you get in touch
You don’t need the technical terms. Just send:
- Where the property is and what kind of building it is
- Your installation or service records
- Any error code or flashing light on the display
Here’s what helps us quote: the address and the type of property, pictures of the rooms or units, the make and model of any existing system and any symptoms, from error codes to drips. Then call us on 07833 053749 or send an email.
How it works
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. On site, the work takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. Parking and access to the outside wall or roof are the main things to plan for a job in Stevenage.
- 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.
- A fixed-price quote follows, setting out the system, any grant that applies and the VAT.
- Fitting day: the outdoor unit is placed, the indoor side connected and the controls set up.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
How to prepare
- Let us know if the building has a permit or sign-in process
- Mention any parking restrictions near the property
- Clear access to the fuse board
How to get a quote
Photos are the fastest route to a quote: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Tell us the address and what you need, and many jobs can be priced from that.
Advice
Stevenage: your questions answered
What’s the best way to get a price for air source heat pumps in Stevenage?
Use the quote form, or email, with a description of the job. Simple jobs can be priced from photos; otherwise we arrange a site survey and then give you a fixed-price quote.
Can you do air source heat pumps in Stevenage?
We do: Stevenage falls inside our working area. Tell us a little about the job and we will take it from there.
How soon will you get back to me?
On the same working day you contact us. After that, we agree a survey, diagnosis or installation date that suits you, and you get a fixed price before any work goes ahead.
Do I get paperwork after the visit?
Yes. You get a written record of every visit, and any work on the refrigerant circuit goes in the F-Gas records. Keep them with the manual and the warranty documents.
Do you work on all makes?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For new systems, we recommend a brand and model to suit the job and tell you why.
Will you work on another installer’s system?
Yes. Systems fitted by other companies are fine from all the leading brands. Tell us the make and model and send any paperwork you have.
Who is responsible for leak checks?
The operator of the equipment, working with qualified engineers. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We will work out which band applies to yours.
Managing agents and facilities teams in Stevenage
Under the GB F-gas rules, responsibility for leak checks is shared between whoever operates the equipment and the engineers who work on it. In a let or managed building, it’s worth agreeing who that operator is and we are happy to deal with whoever it is.
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.
System by system
Outdoor unit position and planning
Where the outdoor unit goes depends on airflow, access and the route into the house. Noise is part of the MCS 020(a) check, so we consider nearby homes too.
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 is not covered, so check with the council.
A customer’s words
“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.”
