Air source heat pumps in Lashenden, done properly
Many air source heat pumps can be installed as permitted development in England, without a planning application. Conditions include a maximum outdoor unit size of 1.5 m³, compliance with MCS 020(a), use for more than cooling alone and a site outside the curtilage of a listed building. We check the rules for your property as part of the survey. If the problem is questions about listed buildings or conservation areas and checking eligibility for a heat pump grant, we can help.
Homes around Lashenden typically have room outside for a heat pump, so the design focuses on heat loss and radiators.
Nothing is signed off by word of mouth: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. File it with the manual, because it helps with any later warranty question.

How the visit works
Where something has to be switched off during the work, we agree it with you first, so you can plan around it. For businesses, we can typically work room by room or zone by zone. On site, it takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. If a lane or gateway near Lashenden is tight for a van, let us know and we’ll plan for it.
- We find out about your home and the heating you have now.
- 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.
- Cost, grant and VAT appear on one fixed-price quote.
- Then it’s fitted, commissioned and registered with MCS.
Getting ready for the visit
- Tell us about any building rules, permits or sign-in
- Clear a path to the units and the space around them
- Tell us about access, such as roof hatches, high walls or locked plant areas

Lashenden questions
Can I get the Boiler Upgrade Scheme grant in Lashenden?
Yes, the scheme covers homes in England, including Lashenden, if they qualify. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. We hold MCS certification, so the application is ours to make for you.
Will you come out to Lashenden?
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.
How much time does a heat pump install need?
It takes from a couple of days to around a week, depending on the system and how much of the heating changes. The cylinder, the radiators and the pipework make the biggest difference, and we confirm the timing with your quote.
Which brands do you work with?
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 explain why.
Do you offer emergency call-outs?
Yes, day and night. When you call, tell us the make, what’s happening and any error code, and we’ll advise on what to do next.
Can we book visits on a schedule?
Yes. Send details of the systems and how they’re used, and we’ll suggest a schedule with a fixed price. That can include the leak checks the F-gas rules require for larger systems.
Can I do the refrigerant work myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That is the law, not just our preference, and it also matters for the manufacturer’s warranty. We are happy to quote for the full job, supply to commissioning.

What else we do in Lashenden
Safe owner checks
Write down what you notice: error codes, noises, drips, smells or a drop in performance. It makes our diagnosis quicker, and a photo or a short video of the display is even better.
On air conditioning, the filters in the indoor unit are typically the one part owners can clean where the manufacturer’s manual explains how. They come out, get a gentle clean and go back only when they’re dry. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
Homes in Lashenden and heat pumps
The middle of Lashenden is part of a conservation area. Draw a one-mile circle round the middle of Lashenden and it takes in 2 conservation areas. About 4 listed entries lie within half a mile of central Lashenden, Lashenden Farmhouse (grade II) among them. So the heat pump survey asks two extra questions here: is the home listed, and is it inside a conservation area? Census 2021 figures found about 75% of households in detached or semi-detached houses. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these.
A heat loss calculation decides the size of heat pump your home needs. Grant applications go through the MCS certified installer, so that part is handled for you.

Why it’s worth doing now in Lashenden
Radiators that are too small for a heat pump’s lower flow temperature leave rooms cool. Checking and upsizing them as part of the installation avoids that. Small faults tend to grow, so it’s worth dealing with them early.
