How we handle air source heat pumps in Round Bush
A £2,500 grant is available for some air-to-air heat pumps, with conditions. It has to replace the fossil-fuel heating, cover the whole heating demand, be fitted by an MCS certified installer and be in a home, so an add-on next to a boiler is not eligible. If the problem is not knowing whether a grant applies and comparing heat pump types, we can sort it out.
In a place like Round Bush, some homes are listed, and permitted development does not cover listed buildings, so we check consent first.
Refrigerant work is written up in the F-Gas records: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, ready for the next service or a warranty query.

How it works
Our engineers bring the tools, gauges and access equipment the job needs. All we ask is clear access to the units, or to where they’ll go, and to the consumer unit. On site, the work takes anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes. We plan the trip to Round Bush around you.
- It starts with a conversation about the home, the existing heating and your plans.
- We survey the home room by room for heat loss, and check the emitters, hot water and outdoor unit position.
- We send a fixed-price quote that shows the equipment, the grant position and the VAT.
- Fitting day: the outdoor unit is placed, the indoor side connected and the controls set up.
- The system is commissioned and registered under MCS, and we show you how to use it.
How to prepare
- Mention any parking restrictions near the property
- Arrange for someone to be there to let us in

Advice

Also in Round Bush
What we’re called out for in Round Bush
A common reason is wanting to stop burning gas, oil or LPG. With a heat pump, the heat comes from the air outside and the system runs on electricity and that’s the appeal for many households.
The things we’re asked about most are:
- Radiators that may be too small for a heat pump
- Wanting to stop using oil, LPG or gas for heating
- Deciding on the outdoor unit position
Live in one of the older houses around Church of St John the Baptist? Expect the survey to look closely at heat loss and at the building’s planning status.
What your quote should include
- What the manufacturer’s warranty covers and for how long
- Whether the quote is a fixed price
- Whether the electrical work is done by a registered contractor, such as NICEIC approved
Landlords, agents and facilities managers
We also work for facilities teams in offices, schools and public buildings across Hertfordshire. Larger buildings can be done in stages around the people who use them.
Larger air conditioning systems in buildings need more than servicing: a TM44 inspection by an accredited energy assessor is required at least every 5 years for systems over 12 kW. We arrange the inspection, get the system ready and put right anything it picks up.
Air source heat pumps in Round Bush: the local picture
About 71% of households live in detached or semi-detached houses, according to the last census (2021). Detached and semi-detached houses typically have room for the outdoor unit and a cylinder.
With High Elms Manor about 2.9 miles north-west, it’s worth asking whether your own home is listed before planning a heat pump.

Your questions about air source heat pumps in Round Bush
Is Round Bush within the area you cover?
Yes, and the size of the place makes no difference to how we work. A few photos and the postcode are enough to get things started.
Do I need planning permission for a heat pump in Round Bush?
That depends on the building and where the outdoor unit goes. The Round Bush Conservation Area takes in the middle of Round Bush. 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 do not 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 the local planning authority (for Round Bush, typically Hertsmere council).
Which accreditations do you hold?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, plus Checkatrade membership. Engineers who handle refrigerant hold their own F-gas qualifications as well.
Can I do the refrigerant work myself?
Not the refrigerant work. The F-gas rules require certified companies and qualified engineers for it, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
Why use an F-Gas certified company?
For refrigerant work, both the engineer and the company need the right F-gas credentials. It’s worth checking before booking, and we’re happy to show ours.
How long does a heat pump installation take?
Expect it to take from a couple of days to around a week, depending on the system and how much of the heating changes. How much of the heating changes decides most of the time, and we confirm the timing with your quote.
Do I need new radiators for a heat pump?
That depends on the room’s heat loss and the radiator’s size. We check them all during the survey, so the quote covers any changes.
Why deal with it now?
For eligible off-gas homes on oil or LPG, an extra £1,500 is on offer until March 2027. If that applies to you, it’s worth asking about sooner rather than later. Small faults tend to grow, so it’s worth dealing with them early.
Leaving a fault or an overdue service rarely makes the work cheaper. Faults and wear in a system tend to grow, and a system working harder than it should costs more to run. If you are not sure what’s needed, call 07833 053749 or send an email for straight advice and a fixed price.

“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.”
