Barwell questions
Does the Boiler Upgrade Scheme cover homes in Barwell?
Barwell is in England, where the Boiler Upgrade Scheme runs. 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. You do not apply yourself: the MCS certified installer does, which is us.
Do I need permission to put air conditioning in my flat in Barwell?
In many cases, yes, once the lease and the building’s rules are checked. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.
Do you provide F-Gas records?
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.
Do you offer maintenance contracts?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Every visit is recorded and F-Gas records kept where they apply.
Do I need to service the system to keep the warranty?
It depends on the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so it’s worth checking. Either way, keep a record of every service.
Whose job is it to check the system for leaks?
Responsibility is shared between the operator, normally whoever owns or controls the equipment, and the service technicians. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
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.
Air source heat pumps in Barwell
Air-to-air heat pumps can qualify for a £2,500 Boiler Upgrade Scheme grant, but only in some cases. It has to replace the fossil-fuel heating, cover the whole heating demand, be fitted by an MCS certified installer and be in a home, so an add-on next to a boiler is not eligible. Common call-outs are for checking emitters for a heat pump and finding a place for the outdoor unit, across homes heated by oil, LPG or gas, hot water cylinders and air-to-water heat pumps.
A terrace in Barwell shares walls with its neighbours, which helps keep heat in, provided the outdoor unit can sit somewhere that passes the MCS noise check.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. If that applies to your system, booking the service on time keeps the record straight, and every service is written up.

For landlords and property managers
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 can work for either side.
We also work for facilities teams in offices, schools and public buildings across Greater London. Work can be phased by floor, zone or building around the people who use them.
How the visit works
Wherever the system can be run before we leave, we run it and check it in operation. Then we show you what we have done and answer any questions, and anything that needs a follow-up is pointed out there and then. The visit takes anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes.

Safe owner checks
Refrigerant is off limits for anyone without the right qualifications. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and escaping refrigerant can cause cold burns. A suspected leak is our job, not yours.
Don’t move, re-route or disconnect units or pipework yourself. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrics need care too. If you need something moved, we can quote for it.
How we price air source heat pumps
A fixed price needs a few facts first. We check:
- What electrical work the job needs
- The number of rooms, units or zones
- The type of system, from a single split to a larger system
Whatever the property, the quote works the same way: the equipment, the access, the work involved and the time it takes. Call for a fixed-price quote and we’ll go through it with you.
Asking for a quote
There’s no need for technical detail. Just send:
- The rating plate or label on any existing unit
- The paperwork from the last service, if you have it
- The postcode and whether it’s a home, flat or business
VAT is set out clearly on every quote, with the rate that applies to your job. VAT can differ between homes and businesses and between kinds of work, so we confirm it in writing rather than guess. To get one, call 07833 053749 or send an email.

Heat pumps in Barwell: local notes
About 45% of homes in Barwell and the neighbourhoods around it date from 1945 to 1972, according to VOA council tax data. Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period. In London, outside space and the rules for flats often decide which kind of heat pump suits.
Homeowners near Chessington South station often ask whether a heat pump can take over from the boiler, and the heat loss survey answers that. Historic houses such as Fitznells Manor, about 2.9 miles east, are a reminder that listed homes need consent before a heat pump goes in.
