Air source heat pumps in Colney Street, done properly
We begin with a room-by-room heat loss survey. It shows how much heat each room needs on a cold day, so the heat pump and the radiators or indoor units can be sized properly. Sizing by rule of thumb is not good enough. If the problem is checking whether planning permission is needed and working out where a cylinder could go, we can help.
Older and listed homes in villages like Colney Street need extra care, because permitted development does not apply within the grounds of a listed building, so consent comes first.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

Where a tenant occupies the property but the landlord owns the system, the lease or tenancy agreement normally sets out who maintains what. We’re happy to deal with either side, and the paperwork can go to both.

Advice
Heat pumps in Colney Street: local notes
About 40% of homes in the Colney Street area date from 1945 to 1972, according to the Valuation Office Agency’s council tax figures, and about 62% of households live in detached or semi-detached houses, according to the last census (2021). Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period. Detached and semi-detached houses usually have room for the outdoor unit and a cylinder.
Older homes near Church of the Holy Trinity may need extra checks for planning and heat loss before a heat pump is designed. High Elms Manor lies about 2.9 miles west. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions.

What affects the quote in Colney Street
Every job gets its own quote. These are the things that affect it:
- What state the existing equipment is in
- A single visit or a regular plan
- Whether we need access equipment for high-level work
Putting the work off seldom saves money. Faults and wear in a system tend to grow, and a struggling system uses more electricity to do less. If you’re unsure, phone 07833 053749 or write to us at info@aircondoctor.co.uk for straight advice and a fixed price.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- A short video of any fault, such as a noise or a flashing light
- The paperwork from the last service, if you have it
- The outdoor side of the property, including any roof or flat area
Every quote shows the VAT clearly, with the rate that applies to your job. VAT can differ between homes and businesses and between kinds of work, so we confirm it on the quote. To get one, ring us on 07833 053749 or drop us a line.
Questions from Colney Street
Is planning permission needed for a heat pump in Colney Street?
The answer turns on the property and where the outdoor unit would sit. Around 6 listed entries sit within 0.5 miles of central Colney Street. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights don’t reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask St Albans City council, which is usually the planning authority for Colney Street.
Is Colney Street within the area you cover?
Yes, smaller places are covered as well as towns. Send a few details and photos, and we reply the same working day.
Does the grant cover air-to-air heat pumps?
Sometimes, and the amount is £2,500 rather than £7,500. It must replace fossil-fuel heating and meet the full heating demand of a home, installed by an MCS certified installer.
How do you keep the place clean during the work?
We start with protection: dust sheets over floors and anything close to the work. Any drilling is agreed with you first, and we clear up the dust and offcuts before we leave.
What does an air-to-water heat pump cost?
For air-to-water, it’s £8,000–£16,000 (0% VAT on homes) before any Boiler Upgrade Scheme grant. Air-to-air systems are priced after a survey, with the VAT confirmed on your quote.
Do you work on commercial properties?
Yes. Homeowners, landlords, agents and businesses all book us across London and the South East. Let us know who the records should go to.
How soon will you get back to me?
The same working day. After that, we agree a survey, diagnosis or installation date that suits you, with a fixed price before work starts.
