Riddlesdown air source heat pumps
For MCS certified installation of air source heat pumps for heating and hot water, with the Boiler Upgrade Scheme grant applied for in Riddlesdown, one call is all it takes, from the first look to sign-off. F-Gas certified, NICEIC approved and Checkatrade members.
- Checking emitters for a heat pump
- Finding a place for the outdoor unit
- No space for a hot water cylinder
What we do, step by step
On the day, we arrive at the time agreed with you and run through the plan before anything else. Floors and furniture near the work are covered with dust sheets, and the electrics are made safe before any panel comes off. On site, it takes a few days on site, depending on the cylinder, the radiators and the pipework involved. If your building in Riddlesdown has a managing agent, a concierge or sign-in rules, mention them when you book.
- Step one is understanding the house, how it’s heated today and what you’d like to change.
- The survey measures heat loss room by room and looks at radiators, hot water and the best spot for the outdoor unit.
- A fixed-price quote follows, setting out the system, any grant that applies and the VAT.
- Fitting day: the outdoor unit is placed, the indoor side connected and the controls set up.
- We commission the heat pump, complete the MCS paperwork and talk you through the controls.
Before we arrive
- Plan for pets to be kept clear during the visit
- Let us know if the units are on a roof, a high wall or in a locked area
- Tell us about any building rules, permits or sign-in
Ask for a 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, you get a fixed price before any work is booked.

How we handle air source heat pumps in Riddlesdown
An air-to-water heat pump heats water to a lower temperature than a typical boiler, so radiators may need to be larger to give out the same heat. The survey shows which rooms are fine and which need changes and anything that needs changing is in the quote. We are often asked to deal with an oil, LPG or gas boiler near the end of its life and deciding which kind of heat pump suits the home, on air-to-water heat pumps, radiator systems and hot water cylinders.
A terrace in Riddlesdown shares walls with its neighbours, which helps keep heat in, as long as there’s a sensible spot for the outdoor unit and its noise is checked against the MCS planning standard.
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, as a manufacturer or a future engineer may ask to see them.

After we’ve gone
Looking after the system is mostly common sense. Our tips:
- Check eligibility for the Boiler Upgrade Scheme early
- File the MCS certificate safely
- Leave indoor units unobstructed
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.
A well-insulated home helps a heat pump, as lower heat loss means the system has less to do.
What affects the cost of air source heat pumps
The price is fixed before any work begins. It’s based on:
- How easy the units are to reach
- The number of rooms, units or zones
- The brand, model and parts involved
Every job is different, so we price each one individually. The equipment, how we reach it, the route between units and the work needed all make a difference.
Asking for a quote
When you call or email, it’s useful to have:
- A short video of any fault, such as a noise or a flashing light
- Wide photos of the room or the existing unit
- The postcode and whether it’s a home, flat or business
Getting a quote is straightforward. Call or email with a few details and we will come back to you the same working day. If we need to see the property first, we book a survey at a time that works for you.

What a heat pump looks like in Riddlesdown
VOA council tax data show about 32% of homes across Riddlesdown and its surrounding area date from 1919 to 1939, and the last census (2021) found about 66% of households in detached or semi-detached houses. Homes of that age often have cavity walls that may or may not be insulated, which the survey checks. Houses typically have space for an outdoor unit and a hot water cylinder. London homes can be short of space for an outdoor unit and cylinder, which affects the choice of heat pump.
Live in one of the older houses around St Edmund's Church? Expect the survey to look closely at heat loss and at the building’s planning status.

Common questions in Riddlesdown
Is the heat pump grant available in Riddlesdown?
Yes, if the home and the heat pump meet the scheme’s rules: Riddlesdown is in England, where it applies. Whether your home qualifies, and for how much, depends on the type of heat pump and the heating it replaces. You don’t apply yourself: the MCS certified installer does, which is us.
Can you fit air conditioning in a London flat in Riddlesdown?
Normally, yes, though leaseholders normally need the freeholder’s agreement. We look at where the outdoor unit could go, such as a balcony, flat roof or rear wall, and write it up for the freeholder or agent.
Which accreditations do you hold?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, and we are Checkatrade members. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
Do you look at the job first?
Yes, always. We diagnose before we treat: the survey tells us what the job needs and how to do it and the fixed price is built on it.
Can I do the refrigerant work myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That is a legal requirement, and manufacturers expect it for their warranty too. We’re happy to quote for the full job, supply to commissioning.
What does F-Gas certified mean?
For refrigerant work, both the engineer and the company need the right F-gas credentials. Ask to see proof before you book anyone, and we are happy to show ours.
How quickly will you reply?
The same working day. After that, we agree a survey, diagnosis or installation date that suits you, and you get a fixed price before any work goes ahead.
When to call us in Riddlesdown
An ageing boiler is often the moment people start thinking about a heat pump. 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.
Most people get in touch when they notice something like this:
- A boiler that is getting old
- Radiators that may be too small for a heat pump
- Planning and permitted development questions
With Addington Palace about 3 miles north-east, it’s worth asking whether your own home is listed before planning a heat pump.
