Homes in Trolliloes and heat pumps
The last census (2021) found about 85% 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. At about 44 miles from central London, Trolliloes sits inside the area we cover across London and the South East.
With Horselunges Manor about 3.7 miles south-west, it’s worth asking whether your own home is listed before planning a heat pump.

How we handle air source heat pumps in Trolliloes
Air-to-water heat pumps heat your hot water through a cylinder. Homes with a combi boiler may not have a cylinder, so finding space for one is part of the survey. Air-to-air systems don’t heat hot water, so you’ll need another way to do that. Typical jobs include finding a place for the outdoor unit and a boiler that’s getting old, across air-to-water heat pumps, underfloor heating and homes heated by oil, LPG or gas.
If your home in or near Trolliloes is heated by oil, LPG or electric heaters with no mains gas, an extra £1,500 is available through the Boiler Upgrade Scheme until March 2027.
We are an F-Gas certified company, NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

Trolliloes: your questions answered
Is Trolliloes 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.
Does the Boiler Upgrade Scheme cover homes in Trolliloes?
Yes, if the home and the heat pump meet the scheme’s rules: Trolliloes is in England, where it applies. 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 is not an add-on to a boiler. The installer applies, and we are MCS certified.
Is the equipment covered by a warranty?
It’s the manufacturer’s, and the terms are theirs. Some terms depend on regular servicing by a qualified engineer, so keep your service records.
Do I need new radiators for a heat pump?
We find out during the survey. Rooms where the radiator is big enough stay as they are and any changes are in the quote.
Do you offer emergency call-outs?
Yes, 24/7. Call the emergency line and tell us the make, the symptoms and any error code, and we will advise on what to do next.
Can I fit air conditioning or a heat pump myself?
No, not the refrigerant side. 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.
Is there a survey before the work?
Yes. Every job is looked at first, either on a site survey or from photos and details for simple jobs. Then you get a fixed-price quote.
What air source heat pumps cannot fix
Not every problem is solved by air source heat pumps, and we will tell you before we start. It does not solve:
- Disconnecting or servicing a gas boiler
- Tax rulings, which only HMRC can give
- Insulation work, such as loft or cavity wall insulation
If you are not sure, just ring us on 07833 053749 or use the quote form and we will give you a straight answer before you book.

- Hot water cylinders
- Underfloor heating

What you can do yourself, and what needs us
On air conditioning, the filters in the indoor unit are normally the one part owners can clean, if the manual says so. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Never try to top up, release or handle refrigerant yourself. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and refrigerant lines can cause cold burns. A suspected leak is our job, not yours.
Common problems we fix in Trolliloes
Many people look at heat pumps when an oil, LPG or gas boiler is getting old. Planning the change before the boiler fails gives you time to survey, design and apply for any grant, rather than rushing a replacement in winter.
These are the situations we see most often:
- Not knowing whether a grant applies
- Working out where a cylinder could go
- Comparing heat pump types
A heat loss calculation decides the size of heat pump your home needs.
Comparing quotes
- Who does the electrical work, and whether they can certify it
- What happens if the job turns out to be different on the day
- How VAT is shown, and which rate applies

How the visit works
On the day, we arrive at the time agreed with you and check the plan with you first. Dust sheets go down over floors and anything close to the work, and anything electrical is made safe before work starts. On site, it takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. For a place like Trolliloes, the timing is set with you and the travel is our side of the planning.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- A heat loss survey works out how much heat each room needs, and we look at the radiators, the cylinder space and where the outdoor unit could go.
- A fixed-price quote follows, setting out the system, any grant that applies and the VAT.
- We fit the outdoor unit and connect it to the heating, hot water and controls.
- We commission the heat pump, complete the MCS paperwork and talk you through the controls.
How to prepare
- Tell us about any building rules, permits or sign-in
- Mention any roof access, ladders or high-level work
- Make sure we can reach the consumer unit or fuse board
