Managing agents and facilities teams in Welwyn Garden City
The F-gas rules share responsibility for leak checking between the equipment’s operator and the service technicians. Where a building is let or managed, the lease or contract should make clear who looks after the system and we are happy to deal with whoever it is.
For anyone managing more than one building, we can quote and plan the work across all of them. Every address has its own paperwork, so each one has its own history.
Air source heat pumps in Welwyn Garden City, 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 isn’t good enough. If you’re dealing with an oil, LPG or gas boiler near the end of its life and not knowing whether a grant applies, we can sort it out.
Most homes around Welwyn Garden City have space for the outdoor unit, and it needs to meet the MCS noise check to be permitted development.
Aftercare is simple, and most of it is in the manual: clear space around the outdoor unit, the cleaning the manual describes and a service at the recommended interval. It also keeps you on the right side of any warranty terms that ask for servicing.

Heat pumps in Welwyn Garden City: local notes
About 35% of homes across Welwyn Garden City and its surrounding area have been built since 2000, according to VOA council tax data, and about 41% of households live in terraced houses, according to Census 2021 figures. Better insulated, newer homes are often a good match for a heat pump. Terraced houses share walls with neighbours, which helps, but the outdoor unit position needs care with noise next door. In the mile around Welwyn Garden City’s centre, 3 conservation areas have been designated. Where a home is affected, the outdoor unit position is settled with Welwyn Hatfield council, normally the planning authority here before the heat pump design is finished.
If your home is listed, like Digswell House about 1.5 miles north, listed building consent comes before any heat pump work. Period properties close to Church Of Saint Francis Of Assisi can suit a heat pump, though insulation and any heritage protection are checked first.

How it 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 a few days on site, depending on the cylinder, the radiators and the pipework involved. A visit in Welwyn Garden City is booked for a time that suits you.
- It starts with a conversation about the home, the existing heating and your plans.
- The survey measures heat loss room by room and looks at radiators, hot water and the best spot for the outdoor unit.
- The price comes back fixed and in writing, with the grant and VAT shown line by line.
- Installation covers the outdoor unit, the indoor connections and the controls.
- Once it’s running correctly, the MCS certificate is issued and we show you the settings.
How to prepare
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Move furniture away from the wall where we will be working
- Let us know if the building has a permit or sign-in process

What owners can safely do
Don’t 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. If you need something moved, we can quote for it.
There are a few things you can safely do yourself: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Opening up the units, the electrics and the refrigerant circuit are a job for us.
Welwyn Garden City questions
Is Welwyn Garden City in your area for air source heat pumps?
Yes, Welwyn Garden City is within the area we cover. Get in touch with the details and we reply the same working day.
Is the heat pump grant available in Welwyn Garden City?
Yes, if the home and the heat pump meet the scheme’s rules: Welwyn Garden City is in England, where it applies. 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.
Does servicing affect my warranty?
Check the manufacturer’s terms. Some manufacturers make regular servicing by a qualified engineer a condition of the warranty, so check the terms or ask us. Keep every service record either way.
Is the equipment covered by a warranty?
Warranty is the manufacturer’s own, on its terms. Each brand sets its own conditions and periods, so we explain them on your quote.
Will I need planning consent for an air source heat pump?
Under the Planning Portal rules, a heat pump on a house can often be permitted development. Listed buildings are excluded, and listed building consent is separate. We check what applies to you.
How much time does a heat pump install need?
The work takes from a couple of days to around a week, depending on the system and how much of the heating changes. We confirm the timing after the survey, so ring 07833 053749 or email us to arrange one.
Can I do the refrigerant work myself?
No, not the refrigerant side. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new electrical circuit is notifiable building work unless a registered competent person does it.
A customer’s words
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
