Air source heat pumps near Lye Green

Air source heat pumps in Lye Green

As an MCS certified installer, we fit air source heat pumps for homes in Lye Green and the rest of Buckinghamshire. There are two kinds: air-to-water, which heats radiators or underfloor heating and your hot water, and air-to-air, which warms rooms through indoor units and can also cool. We will explain which type fits your home and why. If you are dealing with questions about where the outdoor unit can go and ageing boilers that will need replacing, we can sort it out.

In a place like Lye Green, some homes are listed, and permitted development doesn’t cover listed buildings, so we check consent first.

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. That also helps where the warranty terms ask for regular servicing.

When it’s something else

We will not sell you work that does not address the problem, so here are the limits:

  • Planning approval where permitted development does not apply
  • Any gas work on the existing boiler
  • Tax rulings, which only HMRC can give

If in doubt, call us on 07833 053749 or drop us a line and we will say what we think.

What the work covers

  • Air-to-water heat pumps
  • Air-to-air heat pumps
  • Homes heated by oil, LPG or gas
  • Underfloor heating
  • Hot water cylinders
  • Radiator systems

How it works

Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, while the electrical side is covered by our NICEIC approval. So on the day, you do not need a separate electrician for the electrical side. The work takes from a couple of days to around a week, depending on the system and how much of the heating changes. A note on how to find the property and where to park makes a visit to Lye Green easier.

  1. We start with your plans and the property.
  2. We survey for heat loss and look at radiators, cylinder space and outdoor unit options.
  3. You get our view on the right type for the house, and on whether the Boiler Upgrade Scheme applies.
  4. We install the heat pump and connect it up.
  5. After commissioning, you get the MCS certificate and a handover.

Before we arrive

  • Let us know where we can park and unload
  • Tell us about any building rules, permits or sign-in
  • Name a contact who can meet us at the agreed time

Rented and managed buildings

Records are where property maintenance often slips. Each visit produces a dated record, with F-Gas records wherever refrigerant work is involved, ready for a tenant, a buyer or an inspection.

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 the files stay tidy.

What affects the quote in Lye Green

Jobs vary more than people expect. The main factors:

  • The electrical supply and whether a new circuit is needed
  • How easy the units are to reach
  • The pipe route between the units

The pipe route, the height of the units and how we reach them all affect the cost. We take each of them into account, and the price is fixed before any work starts.

Asking for a quote

When you call or email, these details help:

  • A close-up of the unit’s label showing the model number
  • Any error code or flashing light on the display
  • Where the property is and what kind of building it is

To help us quote: the address and the type of property, a few pictures, the brand and model of anything already fitted and anything you’ve noticed, such as an error code or a noise. Once you have those, call us on 07833 053749, or email if that’s easier.

Your questions about air source heat pumps in Lye Green

Will you come out to Lye Green?

Yes, smaller places are covered as well as towns. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.

Can I fit a heat pump in Lye Green without planning permission?

There’s no single answer: the building and the outdoor unit position decide it. Historic England lists about 5 buildings and structures within half a mile of the centre of Lye Green. Heat pumps on houses are often permitted development, but listed buildings need consent and conservation areas restrict outdoor units facing a road. Where it’s needed, we check with the planning department at Buckinghamshire council, normally the authority for Lye Green.

What’s the price of a heat pump installation?

For air-to-water, it’s £8,000–£16,000 (0% VAT on homes) before any Boiler Upgrade Scheme grant. Air-to-air prices are set after a survey, and we confirm the VAT on the quote.

Why use an F-Gas certified company?

Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. Ask to see proof before you book anyone and we will gladly show you ours.

Who is responsible for leak checks?

Whoever operates the equipment, together with the technicians who service it. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We can tell you which band your system falls into.

Do I need new radiators for a heat pump?

We find out during the survey. Where a radiator is already large enough, it stays, and any that need upsizing are set out in the quote.

Does servicing affect my warranty?

For some brands, yes. Send us the make and model and we’ll tell you what the manufacturer expects and stick to the interval they set.

Homes in Lye Green and heat pumps

The Valuation Office Agency’s council tax figures date about 42% of homes in and around Lye Green to the post-war years, 1945 to 1972. Homes of that age often have cavity walls that may or may not be insulated, which the survey checks.

If your home is listed, like Chenies Manor House about 3.8 miles south-east, listed building consent comes before any heat pump work. If your home is one of the older properties near St George's Church, the survey checks whether it’s listed or in a conservation area before the outdoor unit position is chosen.
