Rented and managed buildings
Landlords, letting agents and managing agents book us, not only the people who live or work in the property. Let us know who will give us access and who the records should go to, and we’ll keep everyone informed.
Where a tenant occupies the property but the landlord owns the system, the lease or tenancy agreement normally sets out who maintains what. We are happy to deal with either side and send the records to whoever needs them.
How we handle air source heat pumps in Merle Common
As an MCS certified installer, we fit air source heat pumps for homes in Merle Common and the rest of Surrey. 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 underfloor heating, hot water cylinders and homes heated by oil, LPG or gas, and the jobs we see most are not knowing whether a grant applies and replacing a combi boiler with a heat pump.
Space for an outdoor unit is rarely an issue near Merle Common, so the design comes down to heat loss, radiators and hot water.
The records are your system’s health record: a dated account of the work and the readings we took. It makes the next visit quicker and any warranty question simpler, so keep it safe.

Homes in Merle Common and heat pumps
About 42% of homes in the Merle Common area date from 1945 to 1972, according to the Valuation Office Agency’s council tax figures, and about 63% of households live in detached or semi-detached houses, according to the 2021 Census. For homes of that age, the survey checks the insulation, the radiators and the hot water setup. Houses typically have space for an outdoor unit and a hot water cylinder.
Chartwell, roughly 3.3 miles north-east, is a reminder to check your home’s listing status: permitted development doesn’t cover listed buildings. A heat loss calculation decides the size of heat pump your home needs.

What else we do in Merle Common
What happens on the day
Protection comes first: sheets over the floor and any furniture nearby, and we ask before moving anything. Then the electrics are made safe and the work begins. The work on site takes several days for an air-to-water system with a new cylinder, less for an air-to-air system, and we clear up before we go. Somewhere like Merle Common, it helps to know about lanes, gates and where to park.
- You tell us about the home and what you want from a heat pump.
- A survey covers heat loss, radiators, hot water and where the outdoor unit could sit.
- We recommend air-to-water or air-to-air and check the grant position.
- We install the heat pump and connect it up.
- The job ends with commissioning, the MCS certificate and a walk through the controls.
Before we arrive
- Make sure we can reach the outdoor unit, or where it will go
- Let us know if the units are on a roof, a high wall or in a locked area
- Keep pets out of the rooms we’re working in
Get a fixed-price quote
Photos are enough for some jobs; others need a visit first. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, the quote is fixed before anything goes ahead.

Safe owner checks
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do where the manufacturer’s manual explains how. They come out, get a gentle clean and go back only when they’re dry. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
Do not 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.
Your questions about air source heat pumps in Merle Common
Can I get the Boiler Upgrade Scheme grant in Merle Common?
Merle Common is covered, as the scheme runs across England and Wales. The grant is £7,500 for an air source (air-to-water) heat pump and £2,500 for an air-to-air system that replaces the existing fossil-fuel heating. As an MCS certified installer, we apply for it on your behalf.
Will a heat pump in Merle Common need planning permission?
It depends on the property. The half-mile around the middle of Merle Common holds about 6 listed buildings and structures. 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 can’t face a road. Where necessary, we check with the planning department at Tandridge council, normally the authority for Merle Common.
How quickly will you reply?
You will hear from us the same working day. If it’s an emergency, ring the 24/7 line instead.
Why use an F-Gas certified company?
Certification shows a business is approved to work on systems that hold F gas refrigerant. In Great Britain, that certification is a legal requirement, not an optional extra, and we hold it.
Do you provide F-Gas records?
Yes, on every job. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, while repairs and services get a written note of what was found and done.
How much does an air source heat pump cost?
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes) before the grant. The Boiler Upgrade Scheme offers £7,500 to eligible homes in England and Wales though not every home qualifies.
Do you work on commercial properties?
Yes. From a single let flat to offices, shops and public buildings, we work the same way: a look first, a fixed-price quote and written records.
After we’ve gone
How well a system lasts depends on use and care. Here’s what we suggest:
- Book a yearly service
- Check what your manufacturer’s warranty asks of you
- Ask about the grant before you commit
After commissioning, the installation is registered under MCS and you receive the certificate. Keep it with the manufacturer’s paperwork, as you may need it later.
Keep the outdoor unit clear of leaves, plants and stored items. Airflow is what it runs on so keep it unobstructed.
A customer’s words
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
