Air source heat pumps in Cranford
Air-to-air heat pumps can qualify for a £2,500 Boiler Upgrade Scheme grant, but only in some cases. 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. We are often asked to deal with radiators that may be too small for a heat pump and deciding which kind of heat pump suits the home, on radiator systems, underfloor heating and air-to-air heat pumps.
In a flat in Cranford, the lease and the freeholder usually decide where a heat pump can go. Permitted development limits are different for flats, and we check before designing.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we explain those terms on your quote. Terms differ from brand to brand, and we are happy to talk you through them.

How we price air source heat pumps
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The equipment or parts the job needs
- What kind of system it is
- How many units are involved
Height, access and the distance between the indoor and outdoor units all affect the cost. Each of those is built into the quote and give you a fixed price before any work starts.
Asking for a quote
Good photos often save a visit. The most useful are:
- Wide photos of the room or the existing unit
- The postcode and whether it’s a home, flat or business
- Your installation or service records
VAT is set out clearly on every quote, and the rate that applies to your job is stated. VAT can differ between homes and businesses and between kinds of work, so we confirm it on the quote. For a fixed-price quote, phone us on 07833 053749.
Safe owner checks
Before you call us about a fault, a few checks can save a visit: check the mode, the set temperature, the remote’s batteries and the breaker. If the breaker trips a second time, leave it off and phone us on 07833 053749.
On air conditioning, the filters in the indoor unit are normally the one part owners can clean, if the manual says so. 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.
What happens on the day
Think of the visit in three stages: diagnose, treat and sign off. First we check the system or the space against the plan, then the work itself, and finally we test, record and explain. The middle part takes longest, and that takes a few days for most air-to-water installations, with air-to-air systems often quicker. Send us a few phone photos and we can often price a straightforward job in Cranford before visiting.
- We start with your plans and the property.
- A survey covers heat loss, radiators, hot water and where the outdoor unit could sit.
- You get our view on the right type for the house, and on whether the Boiler Upgrade Scheme applies.
- We install the heat pump and connect it up.
- We commission it, complete the MCS certificate and show you how to use it.
Before we arrive
- Have the make and model of any existing unit to hand
- Mention any roof access, ladders or high-level work
- Let us know where we can park and unload
Getting a quote
Photos are the fastest route to a quote: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Add the address and what you’d like done, and simple jobs can often be priced without a visit.
Advice
Heat pumps in Cranford: local notes
VOA council tax data show about 48% of homes across Cranford and its surrounding area date from 1919 to 1939. Homes of that age often have cavity walls that may or may not be insulated, which the survey checks. London homes can be short of space for an outdoor unit and cylinder, which affects the choice of heat pump.
Osterley House, roughly 2.6 miles east, is a reminder to check your home’s listing status: permitted development does not cover listed buildings. Period properties close to The Parish Church of the Good Shepherd can suit a heat pump, though insulation and any heritage protection are checked first.

What else we do in Cranford
Your questions about air source heat pumps in Cranford
Do I need permission to put air conditioning in my flat in Cranford?
Typically, 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.
Is the heat pump grant available in Cranford?
Yes, if the home and the heat pump meet the scheme’s rules: Cranford 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 isn’t an add-on to a boiler. We hold MCS certification, so the application is ours to make for you.
Are my radiators big enough for a heat pump?
It depends on each radiator and the room it heats. At the lower temperatures a heat pump uses, radiators need more surface so we check every radiator against the room’s heat loss.
Do you provide F-Gas records?
Yes, always. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, and repairs and services get a record of the work.
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.
How does the warranty work?
Warranty is the manufacturer’s own, on its terms. Each brand sets its own conditions and periods, so we explain them on your quote.
How quickly will you reply?
The same working day. Then we agree a date that works for you, with a fixed price before work starts.
