- Deciding which kind of heat pump suits the home
- Questions about the Boiler Upgrade Scheme
What happens on the day
Our engineers bring the tools, gauges and access equipment the job needs. All we ask is clear access to the units, or to where they’ll go, and to the consumer unit. The visit takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. Pictures of the space and where the outdoor unit could go let us plan the work in Charlton.
- You tell us about the home and what you want from a heat pump.
- We survey for heat loss and look at radiators, cylinder space and outdoor unit options.
- We explain which type of heat pump suits the home and whether a grant could apply.
- 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
- Tell us about any building rules, permits or sign-in
- Plan for pets to be kept clear during the visit
- Dig out any previous service or F-Gas records

How we handle air source heat pumps in Charlton
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 cannot 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. Typical jobs include deciding on the outdoor unit position and deciding which kind of heat pump suits the home, across underfloor heating, homes heated by oil, LPG or gas and radiator systems.
For a home around Charlton that is off mains gas and heated by oil or LPG, the Boiler Upgrade Scheme adds an extra £1,500 until March 2027 for an air source or ground source heat pump, on top of the £7,500.
Equipment warranty comes from the manufacturer, on its own terms, and we explain those terms on your quote. Terms differ from brand to brand, and we’re happy to talk you through them.

Common questions in Charlton
Does the Boiler Upgrade Scheme cover homes in Charlton?
Yes, if the home and the heat pump meet the scheme’s rules: Charlton is in England, where it applies. 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. You don’t apply yourself: the MCS certified installer does, which is us.
Can you do air source heat pumps in Charlton?
We do: Charlton falls inside our working area. Get in touch with the details and we reply the same working day.
Is there a survey before the work?
Yes. Every job is looked at first, on a survey, or from your pictures and details where the job is simple. Then you get a fixed-price quote.
When will I hear back?
You will hear from us the same working day. For a breakdown that can’t wait, call our 24/7 emergency line.
Which manufacturers do you install and repair?
We install and work on the leading makes, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we will take it from there.
Why use an F-Gas certified company?
For refrigerant work, both the engineer and the company need the right F-gas credentials. Ask to see proof before booking anyone, and we’re happy to show ours.
Do you provide F-Gas records?
Yes. Each visit is written up, and any work on the refrigerant circuit goes in the F-Gas records. Keep them with the manual and the warranty documents.
System by system
Heat loss surveys
The survey covers the building fabric and how air moves through it along with the room sizes.
Radiators and underfloor heating
Heat pumps run at lower flow temperatures, so radiators may need to be larger so we check them against each room’s heat loss.
After we have gone
After the visit, a few habits help:
- Let the heat pump run steadily, as set up at handover
- Leave space around the outdoor unit
- Know the servicing conditions in your warranty
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.
Leave space around the outdoor unit. It needs good airflow to collect heat from outside, so keep it clear all year.
How we price air source heat pumps
The diagnosis comes before the price. We look at:
- What state the existing equipment is in
- Whether it’s a one-off job or part of a maintenance contract
- The type of system, from a single split to a larger system
The price reflects the work, not guesswork. That’s why every job is looked at first, and why the quote is fixed before any work starts.
What we need to know
When you call or email, it’s useful to have:
- Your consumer unit or fuse board
- The make and model of the system, from the label
- The outside wall, roof or yard where the outdoor unit sits or would go
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.
Heat pumps in Charlton: local notes
Charlton is about 16 miles from central London, well within the area we cover from our base in East Grinstead. About 49% of homes across Charlton and its surrounding area date from 1945 to 1972, according to Valuation Office Agency council tax records. Homes of that age often have cavity walls that may or may not be insulated, which the survey checks.
Older homes near Church of St Mary Magdalene may need extra checks for planning and heat loss before a heat pump is designed. Hampton Court Palace, roughly 4.6 miles east, is a reminder to check your home’s listing status: permitted development doesn’t cover listed buildings.
