Air source heat pumps in St Paul's Walden
As an MCS certified installer, we fit air source heat pumps for homes in St Paul's Walden and the rest of Hertfordshire. Air-to-water systems feed your radiators or underfloor heating and hot water cylinder, while air-to-air systems heat rooms directly through indoor units and can cool them too. We help you work out which suits your home. The work covers hot water cylinders, homes heated by oil, LPG or gas and underfloor heating, and common reasons people get in touch are checking whether planning permission is needed and questions about the Boiler Upgrade Scheme.
In a place like St Paul's Walden, some homes are listed, because permitted development does not apply within the grounds of a listed building, so consent comes first.
Nothing is signed off by word of mouth: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. File it with the manual so it’s to hand next time.

How the visit works
Testing is the last part of the visit wherever the system can be switched on. Then we show you what we have done and answer any questions, and anything that needs attention later is pointed out. The visit takes a few days on site, depending on the cylinder, the radiators and the pipework involved. Pictures of the space and where the outdoor unit could go let us plan the work in St Paul's Walden.
- We talk through your home, your current heating and what you want from a heat pump.
- 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.
Preparing for the visit
- Dig out any previous service or F-Gas records
- Keep pets and children away from the work area
- Let us know if the units are on a roof, a high wall or in a locked area

Rented and managed buildings
When the building owner and the occupier are different, the lease or tenancy agreement normally sets out who maintains what. We are happy to deal with either side, and the paperwork can go to both.
We work for landlords, letting agents and managing agents as well as homeowners and businesses. Tell us who the contact on site is and who should receive the paperwork and we will copy in whoever needs it.
Aftercare tips
After the visit, a few habits help:
- Book a yearly service
- Keep the MCS certificate with the manufacturer’s paperwork
- Use the settings explained at handover
After commissioning, the installation is registered under MCS and you receive the certificate. File it with the warranty documents, as you may need it later.
Leave space around the outdoor unit. It needs good airflow to collect heat from outside, so keep it clear all year.

What else we do in St Paul's Walden
Why deal with it now?
If the emitters can’t give out enough heat, some rooms won’t get warm enough. The survey picks this up before installation. Small faults tend to grow, so it’s worth dealing with them early.
Whatever the property, the quote works the same way: the equipment, the access, the work involved and the time it takes. Ask for a fixed-price quote and we will explain each part.

Your questions about air source heat pumps in St Paul's Walden
Will a heat pump in St Paul's Walden need planning permission?
There’s no single answer: the building and the outdoor unit position decide it. Around 24 listed entries sit within 0.5 miles of central St Paul's Walden. 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 cannot face a road. Where necessary, we check with North Hertfordshire council, which is usually the planning authority for St Paul's Walden.
Does the Boiler Upgrade Scheme cover homes in St Paul's Walden?
Yes, the scheme covers homes in England, including St Paul's Walden, if they qualify. Air-to-water and ground source systems attract £7,500. Air-to-air gets £2,500, but only where it takes over from fossil-fuel heating and covers the whole home’s heating demand. We hold MCS certification, so the application is ours to make for you.
Do you protect the property while you work?
We put dust sheets over floors and furniture near the work first, and we tidy up as we go. At the end, we clear up and show you what we have done.
Can I fit air conditioning or a heat pump myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That’s a legal requirement, and it also matters for the manufacturer’s warranty. We are happy to quote for the full job, supply to commissioning.
Which accreditations do you hold?
We are an F-Gas certified company, with NICEIC approval for electrical work and MCS certification for heat pumps. We are members of Checkatrade too.
Is St Paul's Walden in your area?
Yes. St Paul's Walden is part of the area we cover, as part of our area across London and the South East. We’re based in East Grinstead, West Sussex.
Who has to arrange F-Gas leak checks?
The operator of the equipment, working with qualified engineers. 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’ll work out which band applies to yours.
Homes in St Paul's Walden and heat pumps
About 40% of households live in terraced houses, according to the last census (2021). Shared walls keep a terrace’s heat loss down, while gardens next door make the noise check on the outdoor unit important.
With Knebworth House about 2.4 miles south-east, it’s worth asking whether your own home is listed before planning a heat pump. Older homes near All Saints Church may need extra checks for planning and heat loss before a heat pump is designed.
