Porter's End air source heat pumps
We cover Porter's End for MCS certified installation of air source heat pumps for heating and hot water, with the Boiler Upgrade Scheme grant applied for. Diagnosis first, a fixed price and proper paperwork when we finish.
- Radiators that may be too small for a heat pump
- A boiler that is getting old
- Planning and permitted development questions
Common problems we fix in Porter's End
Some homes heated by electric heaters or storage heaters consider a heat pump instead. A survey shows whether a heat pump suits the property and what would need to change, and we explain the grant position for your home.
Reasons to give us a call include:
- An oil, LPG or gas boiler near the end of its life
- Checking whether planning permission is needed
- Deciding which kind of heat pump suits the home
If your home is one of the older properties near St Peter, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.
What to look for in a quote

About our air source heat pumps in Porter's End
We install air source heat pumps in Porter's End and across Hertfordshire, and we’re MCS certified. There are two kinds: air-to-water, which heats radiators or underfloor heating and your hot water, and air-to-air, which warms rooms through indoor units and can also cool. We will explain which type fits your home and why. The work covers homes heated by oil, LPG or gas, hot water cylinders and air-to-air heat pumps, and common reasons people get in touch are working out where a cylinder could go and an oil, LPG or gas boiler near the end of its life.
Homes around Porter's End normally have room outside for a heat pump, so the design comes down to heat loss, radiators and hot water.
We’re an F-Gas certified company, NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

How the visit works
Refrigerant work is done by qualified engineers working for an F-Gas certified company, and electrical work is done by us as NICEIC approved contractors. So on the day, you do not need a separate electrician for the electrical side. On site, it takes a few days for most air-to-water installations, with air-to-air systems often quicker. Photos of the room and the outside of the property help us plan a visit to Porter's End.
- We start with your plans and the property.
- The survey checks heat loss, emitters, hot water and the outdoor unit position.
- We explain which type of heat pump suits the home and whether a grant could apply.
- Installation follows on the agreed dates.
- After commissioning, you get the MCS certificate and a handover.
How to prepare
- Make sure we can reach the consumer unit or fuse board
- Find the manual or the paperwork for the system, if you have it
- Mention any managing agent or landlord rules we need to follow

Air source heat pumps around Porter's End
VOA council tax data date about 42% of homes in the Porter's End area to the post-war years, 1945 to 1972, and about 62% of households live in detached or semi-detached houses, according to the last census (2021). Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period. Detached and semi-detached houses normally have room for the outdoor unit and a cylinder.
Historic houses such as Shaw's Corner, about 2 miles east, are a reminder that listed homes need consent before a heat pump goes in.

Questions from Porter's End
Can I fit a heat pump in Porter's End without planning permission?
That depends on the building and where the outdoor unit goes. The half-mile around the middle of Porter's End holds about 7 listed buildings and structures. 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 cannot face a road. Where necessary, we check with North Hertfordshire council, which is normally the planning authority for Porter's End.
Will you come out to Porter's End?
We do. Villages and hamlets get the same service as the bigger towns. Visits to smaller places are planned so the engineer arrives with what the job needs.
Are you F-Gas certified?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, plus Checkatrade membership. Engineers who handle refrigerant hold their own F-gas qualifications as well.
What does an air-to-water heat pump cost?
For air-to-water, the price is £8,000–£16,000 (0% VAT on homes) before any grant. The Boiler Upgrade Scheme offers £7,500 to eligible homes in England and Wales, and we confirm eligibility before you commit.
How much VAT is charged on a heat pump in a home?
In residential accommodation, 0% until 31 March 2027 and 5% afterwards. Hotels and businesses pay the standard rate, and this is not tax advice.
Why use an F-Gas certified company?
The law says any company working on equipment containing F gas has to be certified, and each engineer needs the right qualifications too. It’s how you know the refrigerant is being handled legally and safely.
Which type of heat pump is right for my home?
Air-to-water replaces the boiler for heating and hot water, while air-to-air heats and cools rooms, and we help you choose. We install both types.
What affects the quote in Porter's End
Before we fix a price, we need to know a few things. We check:
- How many units are involved
- One-off work versus a regular service cycle
- Whether the existing supply is suitable
Height, access and the distance between the indoor and outdoor units can all change the price. We take each of them into account, and the price is fixed before we start.
What to send for a quote
You don’t need the technical terms. Just send:
- The paperwork from the last service, if you have it
- A few pictures of the room and the wall the unit is on, or will go on
- A close-up of the unit’s label showing the model number
For a fixed-price quote, ring us on 07833 053749, or email if that’s easier and tell us about the property and what you need. A few pictures make it quicker. You will hear back from us the same working day.
What air source heat pumps can’t fix
Not every problem is solved by air source heat pumps, and we’ll tell you before work begins. It doesn’t solve:
- Tax advice on your own circumstances
- Any gas work on the existing boiler
- Promising eligibility for the Boiler Upgrade Scheme
Not sure which it is? You can call us on 07833 053749, or email if that’s easier and we will tell you honestly.

“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.”
