After we have gone
Every system needs looking after, and most of it is easy. A few tips:
- File the MCS certificate safely
- Clear leaves and debris from the outdoor unit
- Know the servicing conditions in your warranty
In cold, damp weather the outdoor unit runs a defrost cycle from time to time. You might see steam or hear the unit change note, and that is normal.
Have the system serviced regularly. Your manufacturer’s warranty terms may say something about servicing.
Air source heat pumps in St Albans, done properly
Until 31 March 2027, a heat pump installed in residential accommodation carries 0% VAT, with 5% from 1 April 2027. This is HMRC’s energy-saving materials relief, which applies to homes rather than businesses. For air-to-air systems, we confirm the VAT on your quote. Please treat this as general information rather than tax advice. If the problem is questions about the Boiler Upgrade Scheme and finding a place for the outdoor unit, we can help.
Homes in St Albans range from older houses to new builds, and the age of a home matters a lot for a heat pump. Every design starts with a room-by-room heat loss calculation, so it’s sized properly.
Equipment warranty comes from the manufacturer, on its own terms, and we explain those terms on your quote. Each brand sets its own conditions, so we go through them with you rather than leave you to find the small print.

Air source heat pumps around St Albans
Central St Albans is inside the St Albans Conservation Area. 2 conservation areas lie within a mile of central St Albans. About 92 listed entries lie within half a mile of central St Albans, Clock Tower (grade I) among them. So the heat pump survey asks two extra questions here: is the home listed, and is it inside a conservation area? At about 20 miles from central London, St Albans sits inside the area we cover across London and the South East.
Period properties close to Church of St. Peter can suit a heat pump, though insulation and any heritage protection are checked first. If your home is listed, like Batchwood Hall about 1.5 miles north-west, listed building consent comes before any heat pump work.

Your questions about air source heat pumps in St Albans
Can I get the Boiler Upgrade Scheme grant in St Albans?
Yes, the scheme covers homes in England, including St Albans, if they qualify. For an air-to-water heat pump the amount is £7,500; an air-to-air system can get £2,500 if it replaces the fossil-fuel heating outright, meets the home’s full heating demand and isn’t an add-on to a boiler. As an MCS certified installer, we apply for it on your behalf.
Do you cover St Albans for air source heat pumps?
Yes. We work across London and the South East from our base in East Grinstead, and St Albans is part of that. Tell us a little about the job and we’ll take it from there.
Do you survey before quoting?
Yes. For simple jobs, pictures and a few details can be enough, while bigger systems and repairs that need testing get a visit.
Do you work on commercial properties?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size across London and the South East. Let us know who the records should go to.
Who is responsible for leak checks?
Whoever operates the equipment, together with the technicians who service it. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We can tell you which band your system falls into.
Should I choose air-to-water or air-to-air?
Air-to-water feeds your central heating and hot water, while air-to-air warms and cools rooms directly. Air-to-air does not heat hot water and the survey helps decide.
Do you work on systems someone else installed?
Yes. Systems fitted by other companies are fine from all the leading brands. Tell us the make and model and send any paperwork you have.
Managing agents and facilities teams in St Albans
Keeping records across a portfolio is half the battle. Each visit produces a dated record, with F-Gas records wherever refrigerant work is involved, so you can show what was done and when.
Running several properties is easier with one contractor. Our area covers Greater London and the South East, so work at different addresses can be planned together and kept to a regular schedule.
What happens on the day
The first job on site is protection: sheets over the floor and any furniture nearby, and we ask before moving anything. Then the electrics are made safe and the work begins. It takes a few days for most air-to-water installations, with air-to-air systems often quicker, and we clear up before we go. A few pictures of the room, the outside wall and the fuse board help us plan a job in St Albans.
