- Ageing boilers that will need replacing
- Choosing between air-to-water and air-to-air
- Checking emitters for a heat pump
How it works
The visit has three parts, a bit like a doctor’s appointment: look, put right and sign off. First comes a careful look at the system or the space, then we do the work, and finally everything is tested, recorded and explained. The middle part takes longest, which takes anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes. Send us a few phone photos and we can often price a straightforward job in Cranham before visiting.
- It begins with your house and the heating it relies on now.
- A heat loss survey is carried out, room by room.
- From those figures we size the heat pump and decide on radiators, cylinder and outdoor position.
- A fixed-price quote explains the cost, the grant position and the VAT.
- We install, commission and register the system under MCS.
Getting ready for the visit
- Find the manual or the paperwork for the system, if you have it
- Move furniture away from the wall where we will be working
- Make sure someone can let us in at the agreed time

Air source heat pumps for homes and businesses in Cranham
In England, an air source heat pump on a house can often go in under permitted development rights. The conditions include an outdoor unit of no more than 1.5 m³ and compliance with MCS 020(a), and the unit can’t be used solely for cooling or sit within the curtilage of a listed building. We check the rules for your property as part of the survey. If you are dealing with no space for a hot water cylinder and comparing heat pump types, we can help.
A terrace in Cranham shares walls with its neighbours, which helps keep heat in, provided the outdoor unit can sit somewhere that passes the MCS noise check.
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.

Common problems we fix in Cranham
The Boiler Upgrade Scheme has made people ask whether their home could qualify. Eligibility depends on the property, the system and the scheme rules, so we check before you commit.
Customers normally contact us when they notice one of these:
- An oil, LPG or gas boiler near the end of its life
- Checking whether planning permission is needed
- Working out where a cylinder could go
Homeowners near Upminster station often ask whether a heat pump can take over from the boiler, and the heat loss survey answers that.
What to look for in a quote
- How VAT is shown, and which rate applies
- The make and model of any parts or equipment being quoted
- Whether the company is F-Gas certified, and whether you can check it
Let and managed properties
Portfolio owners often want one contractor and one number. We work across London and the South East, so work at different addresses can be planned together and kept to a regular schedule.
Larger air conditioning systems in buildings need more than servicing: a TM44 inspection by an accredited energy assessor is required at least every 5 years for systems over 12 kW. We can arrange it, prepare the system for it and fix what it finds.
Air source heat pumps in Cranham: the local picture
About 64% of homes in the Cranham area date from 1945 to 1972, according to the Valuation Office Agency’s council tax figures, and about 72% of households live in detached or semi-detached houses, according to the last census (2021). Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period. Finding room for the outdoor unit and a cylinder is seldom a problem in homes like these. London homes can be short of space for an outdoor unit and cylinder, which affects the choice of heat pump.
Period properties close to St Luke's Cranham can suit a heat pump, though insulation and any heritage protection are checked first.

Questions from Cranham
Can you do air source heat pumps in Cranham?
Yes. Cranham is one of the places we cover. To start, ring us on 07833 053749 or drop us a line with a few pictures.
Can I get the Boiler Upgrade Scheme grant in Cranham?
Cranham is covered, as the scheme runs across England and Wales. 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. You don’t apply yourself: the MCS certified installer does, which is us.
Which accreditations do you hold?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
Do I need planning permission for a heat pump?
In England, many air source heat pumps on houses can be permitted development provided the conditions are met. The outdoor unit must be 1.5 m³ or less, comply with MCS 020(a), not be cooling-only and not be within a listed building’s curtilage.
Can I fit air conditioning or a heat pump myself?
Not the refrigerant work. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.
Do I need to service the system to keep the warranty?
Each manufacturer decides. Where servicing is a condition, a missed service could give the manufacturer grounds to refuse a claim and we will tell you what your brand asks for.
Will I get records for the system?
Yes, on every job. 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.
