Honest limits

- Promising eligibility for the Boiler Upgrade Scheme
- Gas boiler work, such as disconnecting the old boiler, which needs a Gas Safe registered engineer
- Insulation work, such as loft or cavity wall insulation

About our air source heat pumps in Letchworth
We install air source heat pumps in Letchworth and across Hertfordshire, and we’re MCS certified. Air-to-water systems feed your radiators or underfloor heating and hot water cylinder, while air-to-air systems heat rooms directly through indoor units and can cool them too. We will explain which type fits your home and why. If you are dealing with not knowing whether a grant applies and a boiler that’s getting old, we can help.
Most homes around Letchworth have space for the outdoor unit, and it needs to meet the MCS noise check to be permitted development.
Some manufacturers make regular servicing by a qualified engineer a condition of their warranty. If that applies to your system, booking the service on time keeps the record straight, and every service is written up.

How it works
Think of the visit in three stages: diagnose, treat and sign off. First we check the system or the space against the plan, then we do the work, and finally we test, record and explain. Most of the time goes on the middle part, which takes a few days on site, depending on the cylinder, the radiators and the pipework involved. In a town like Letchworth, parking is usually straightforward, so the main questions are access and timing.
- First we talk through the property and the current system.
- Every room’s heat loss is worked out on site.
- We design the system, check the radiators and cylinder and look at the outdoor unit position.
- You get a fixed price, with any grant and the VAT set out.
- Installation, commissioning and MCS registration complete the job.
Preparing for the visit
- Make sure we can reach the consumer unit or fuse board
- Make sure someone can let us in at the agreed time
- Keep pets out of the rooms we’re working in

What you can do yourself, and what needs us
Before you call us about a fault, a few checks can save a visit: check the mode, the set temperature, the remote’s batteries and the breaker. If the breaker trips a second time, leave it off and phone 07833 053749 or email us.
Write down what you notice: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It makes our diagnosis quicker, and a photo of the display helps even more.
What a heat pump looks like in Letchworth
Letchworth is about 34 miles from central London, well within the area we cover from our base in East Grinstead. Letchworth’s centre falls inside the Letchworth Conservation Area. Draw a one-mile circle round the middle of Letchworth and it takes in 2 conservation areas. On the National Heritage List, around 41 entries fall within 0.5 miles of the middle of Letchworth; Town Hall (grade II) is one. For a heat pump, permitted development doesn’t apply within the grounds of a listed building, and in a conservation area the outdoor unit can’t go on a wall or roof facing a road, so we check with the planning team at North Hertfordshire council, which usually handles Letchworth where necessary.
If your home is near Letchworth Garden City station and heated by a gas boiler, an air-to-water heat pump can replace it where the survey shows it suits. 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.

Questions from Letchworth
Is Letchworth in your area for air source heat pumps?
Yes. Letchworth is one of the places we cover. Just call 07833 053749 or fill in the contact form with a few details.
Is the heat pump grant available in Letchworth?
Yes, the scheme covers homes in England, including Letchworth, if they qualify. Air-to-water and ground source systems attract £7,500. Air-to-air gets £2,500, but only where it takes over from fossil-fuel heating and covers the whole home’s heating demand. As an MCS certified installer, we apply for it on your behalf.
What does F-Gas certified mean?
The law says any company working on equipment containing F gas has to be certified, and the engineers need their own qualifications. It’s how you know the refrigerant is being handled legally and safely.
Do you offer maintenance contracts?
Yes. We offer maintenance contracts, with visits at the interval your system and the manufacturer need. Each visit is written up and F-Gas records kept where they apply.
Can you look at a system you didn’t fit?
Yes. Systems fitted by other companies are fine from all the leading brands. Send us the make and model, and any records you have.
Do I get paperwork after the visit?
Yes. It’s the record a manufacturer or the next engineer will ask to see: a dated note of the work, with refrigerant details where they apply.
Is a heat pump permitted development?
Many installations on houses in England fall under permitted development, subject to the rules. Listed buildings and their curtilages are excluded, and listed building consent is a separate matter. We check what applies to you.
System by system
Heat loss surveys
The survey works out the heat needed room by room. Everything else is sized from it.
Air-to-water heat pumps
Air-to-water systems work at lower temperatures than boilers, which is why radiator sizing is part of the survey.
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.”
