Common questions in Bernards Heath
Can I fit a heat pump in Bernards Heath without planning permission?
It comes down to the building and the spot chosen for the outdoor unit. Central Bernards Heath is a short walk from the St Albans Conservation Area. Heat pumps on houses are often permitted development, but listed buildings need consent and conservation areas restrict outdoor units facing a road. Where it’s needed, we check with the planning department at St Albans City council, usually the authority for Bernards Heath.
Does the Boiler Upgrade Scheme cover homes in Bernards Heath?
Bernards Heath 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. We hold MCS certification, so the application is ours to make for you.
How long does a heat pump installation take?
Expect it to take a few days for most air-to-water installations, with air-to-air systems often quicker. The cylinder, the radiators and the pipework make the biggest difference, and we confirm the timing with your quote.
How quickly will you reply?
On the same working day you contact us. Then we agree a date that works for you, and you get a fixed price before any work goes ahead.
Do I need to service the system to keep the warranty?
It can, for some brands. Send us the make and model and we will tell you what the manufacturer expects, and book the service at the interval they recommend.
Who has to arrange F-Gas leak checks?
Responsibility is shared between the operator, usually whoever owns or controls the equipment, and the service technicians. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
Why use an F-Gas certified company?
F-Gas certification shows a company is approved to work on equipment containing fluorinated gases, such as the refrigerant in air conditioning and heat pumps. That isn’t optional: it’s required by law, and AirCon Doctor is certified.
Air source heat pumps in Bernards Heath
Heat pumps run at lower flow temperatures than most boilers, so radiators may need to be larger to give out the same heat. The survey shows which rooms are fine and which need changes and anything that needs changing is in the quote. If you are dealing with choosing between air-to-water and air-to-air and questions about where the outdoor unit can go, we can sort it out.
Homes around Bernards Heath normally have space for an outdoor unit and a hot water cylinder, so the main questions are heat loss, radiators and the electrics.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We’ll tell you how the manufacturer’s warranty is likely to apply before any chargeable work goes ahead.

What a heat pump looks like in Bernards Heath
The 2021 Census found about 62% 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.
If your home is near St Albans station and heated by a gas boiler, an air-to-water heat pump can replace it where the survey shows it suits. Older homes near Church of St Saviour may need extra checks for planning and heat loss before a heat pump is designed.
