Lexden air source heat pumps
Our engineers work in Lexden on heat pump installation. A look at the job first, a fixed-price quote and written records at the end.
- Radiators that may be too small for a heat pump
- Not knowing whether a grant applies
- No space for a hot water cylinder
How we handle air source heat pumps in Lexden
Heat pumps run at lower flow temperatures than most boilers, so radiators may need to be larger to give out the same heat. We check each radiator against the room’s heat loss, and the quote sets it out. The work covers hot water cylinders, radiator systems and homes heated by oil, LPG or gas, and people most often call us about wanting to stop using oil, LPG or gas for heating and ageing boilers that will need replacing.
For a house near Lexden, space outside is rarely the problem, so heat loss, radiators and the electrics are what we check.
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.

Homes in Lexden and heat pumps
Lexden’s centre is no more than about a third of a mile from the Colchester Area 3 Conservation Area. In the mile around Lexden’s centre, 2 conservation areas have been designated. Listed buildings are part of the picture here: about 8 within half a mile of the centre, such as Yeoman Cottage (grade II). That affects heat pumps: listed buildings need consent, and conservation areas limit where the outdoor unit can go under permitted development. Where necessary, we check with Colchester council, typically the planning authority here. The Valuation Office Agency’s council tax figures date about 50% of homes in Lexden and the neighbourhoods around it to the post-war years, 1945 to 1972, and about 81% of households live in detached or semi-detached houses, according to the 2021 Census. For homes of that age, the survey checks the insulation, the radiators and the hot water setup. Houses usually have space for an outdoor unit and a hot water cylinder.
If your home is one of the older properties near Church of St Leonard, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen. Every heat pump design starts with a room-by-room heat loss calculation.
Lexden is about 1 mile west of Colchester, in Essex. Whether you are in the middle of Lexden or further out, we cover air source heat pumps, from a single room to a whole building. In Essex alone we list 644 places and Lexden is among them. The nearest of our city pages is London, around 49 miles from Lexden.
Every address in CO3 and CO2 is covered. We cover homes and businesses on Park Road, Heath Road and Capel Road and the roads around them.

What you can do yourself, and what needs us
Do not move, re-route or disconnect units or pipework yourself. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrical side needs a competent person. If you need something moved, we can quote for it.
Refrigerant is off limits for anyone without the right qualifications. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and escaping refrigerant can cause cold burns. A suspected leak is our job, not yours.
Honest limits
It’s worth knowing the limits before booking:
- Grants for hybrid systems or replacements of low-carbon systems
- Tax advice on your own circumstances
- Any gas work on the existing boiler

On site, it takes a few days on site, depending on the cylinder, the radiators and the pipework involved. Around Lexden, access is typically simple, though gates and garden access are worth mentioning.

Advice
Fixed-price quotes for air source heat pumps in Lexden
A fixed price needs a few facts first. We check:
- The condition of any existing system
- The electrical supply and whether a new circuit is needed
- How easy the units are to reach
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 any work starts.
Helping us quote
Photos let us diagnose from a distance. The most useful are:
- Any error code or flashing light on the display
- A photo of the consumer unit with the cover closed
- The make and model of the system, from the label

What else we do in Lexden
Common questions in Lexden
Is the heat pump grant available in Lexden?
Yes, the scheme covers homes in England, including Lexden, if they qualify. 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. The installer applies, and we’re MCS certified.
Do you cover smaller places like Lexden?
Yes. Lexden is within the area we cover across London and the South East. A few photos and the postcode are enough to get things started.
Do you work on systems someone else installed?
Yes. Systems fitted by other companies are fine, on all the main brands. Tell us the make and model and send any paperwork you have.
Can landlords and managing agents book you?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size across London and the South East. Tell us who should receive the paperwork.
How do you keep the place clean during the work?
We put dust sheets over floors and furniture near the work first, and we tidy up as we go. At the end, we clear up and show you what we’ve done.
Can I fit air conditioning or a heat pump myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That is a legal requirement, and it also matters for the manufacturer’s warranty. We are happy to quote for the full job, supply to commissioning.
Should I choose air-to-water or air-to-air?
It depends on your home, your heating and whether you want cooling. Air-to-water can attract a £7,500 grant where eligible; air-to-air only qualifies for £2,500 under strict conditions. We explain the options after the survey.
