- No space for a hot water cylinder
- Deciding on the outdoor unit position
- Not knowing whether a grant applies
How we handle air source heat pumps in London Colney
We begin with a room-by-room heat loss survey. That tells us how much heat the home needs, room by room, so the heat pump and the radiators or indoor units can be sized properly. Guesswork leads to systems that are too big or too small. We’re often asked to deal with deciding which kind of heat pump suits the home and plans to switch to electric heating with a heat pump, across hot water cylinders, air-to-water heat pumps and homes heated by oil, LPG or gas.
Cottages and older homes near London Colney can lose heat faster, so a proper heat loss calculation matters. Sometimes insulating first makes more sense.
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.

FAQs for London Colney
Do you cover smaller places like London Colney?
Yes, smaller places are covered as well as towns. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Can I fit a heat pump in London Colney without planning permission?
There’s no single answer: the building and the outdoor unit position decide it. Around 16 listed entries sit within 0.5 miles of central London Colney. 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 can’t face a road. Where needed, we check with the local planning authority (for London Colney, usually St Albans City council).
Can you come out in an emergency?
Yes, day and night. Call the emergency line and tell us the make, the symptoms and any error code, and we’ll advise on what to do next.
Can landlords and managing agents book you?
Yes. Homeowners, landlords, agents and businesses all book us across London and the South East. Tell us who should receive the paperwork.
What does F-Gas certified mean?
Certification shows a business is approved to work on systems that hold F gas refrigerant. In Great Britain, that certification is a legal requirement, not an optional extra, and we hold it.
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. Each visit is written up and F-Gas records kept where they apply.
Does the grant cover air-to-air heat pumps?
The scheme offers £2,500 for air-to-air, but the conditions are strict. Adding air-to-air alongside a boiler does not qualify as it has to meet the full heating demand.
Why deal with it now?
From 1 April 2027, VAT on heat pumps in homes rises from 0% to 5%. It’s a date to bear in mind when planning alongside your own plans for the property. For a place like London Colney, booking ahead lets us plan the visit properly.
Homes, offices, shops and public buildings are all priced the same way: the equipment, the access, the work involved and the time it takes. Ask for a fixed-price quote and we’ll explain each part.

The process
Our engineers arrive at the time agreed with you and run through the plan before anything else. Dust sheets go down over floors and anything close to the work, and the electrics are made safe before any panel comes off. On site, it takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. A few photos let us plan a visit to a place like London Colney.
- You tell us about the home and what you want from a heat pump.
- The survey checks heat loss, emitters, hot water and the outdoor unit position.
- We recommend air-to-water or air-to-air and check the grant position.
- Installation follows on the agreed dates.
- The job ends with commissioning, the MCS certificate and a walk through the controls.
Preparing for the visit
- Clear the space around the indoor unit, or where it will go
- Make sure we can reach the consumer unit or fuse board
- Mention any parking restrictions near the property
Getting a quote
Here’s what helps us quote: the address and the type of property, pictures of the rooms or units, the brand and model of anything already fitted and any symptoms, from error codes to drips. Then phone 07833 053749 or email us.
Advice
What you can do yourself, and what needs us
Write down what you notice: error codes, noises, drips, smells or a drop in performance. It helps us diagnose quickly, and a photo of the display helps even more.
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 electrics need care too. Ask us to quote for a move instead.

What the work involves, system by system
Outdoor unit position and planning
Under permitted development, the outdoor unit must be 1.5 m³ or less and must meet MCS 020(a) and not be used solely for cooling. Listed building curtilages are excluded.
Air-to-water heat pumps
Flow temperatures are lower than with a typical boiler, which is why radiator sizing is part of the survey.
From one of our customers
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
