Landlords, agents and facilities managers
We work for landlords, letting agents and managing agents as well as homeowners and businesses. Let us know who will give us access and who the records should go to and we’ll copy in whoever needs it.
Records are where property maintenance often slips. Each visit is written up, with F-Gas records wherever refrigerant work is involved, ready for a tenant, a buyer or an inspection.
Air source heat pumps in Walworth
An air-to-water heat pump costs £8,000–£16,000 (0% VAT on homes), before the grant. The Boiler Upgrade Scheme can provide £7,500 towards an eligible air-to-water system in England and Wales, and as the installer we apply for it on your behalf. Eligibility depends on the property, so we confirm it before anything is agreed. The work covers hot water cylinders, air-to-air heat pumps and underfloor heating, and people most often call us about finding a place for the outdoor unit and choosing between air-to-water and air-to-air.
In a flat in Walworth, 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.
Think of the paperwork as the system’s health record: what was fitted or found, what was done and when. It makes the next visit quicker and any warranty question simpler and it’s worth keeping safe.

How we price air source heat pumps
Our prices page gives typical ranges, but every job is priced on its own. The quote depends on:
- One-off work versus a regular service cycle
- The size of the job
- How easy the units are to reach
Height, access and the distance between the indoor and outdoor units can all change the price. We take each of them into account and give you a fixed price before any work starts.
Helping us quote
What to send for a quote:
- Wide pictures of the room or the existing unit
- The outdoor side of the property, including any roof or flat area
- The paperwork from the last service, if you have it
To help us quote: where the property is and what kind of building it is, pictures of the rooms or units, the brand and model of anything already fitted and anything you’ve noticed, such as an error code or a noise. Then phone us on 07833 053749 or send an email.
The process
Our engineers bring the tools, gauges and access equipment the job needs. You only need to give us clear access to the units, or their planned positions, and to the fuse board. The visit takes a few days on site, depending on the cylinder, the radiators and the pipework involved. Some blocks in Walworth need contractor details in advance, so tell us what your building needs.
- We start with your plans and the property.
- The survey checks heat loss, emitters, hot water and the outdoor unit position.
- You get our view on the right type for the house, and on whether the Boiler Upgrade Scheme applies.
- Installation follows on the agreed dates.
- We commission it, complete the MCS certificate and show you how to use it.
Before we arrive
- Tell us about parking and loading
- Clear access to the fuse board
- Name a contact who can meet us at the agreed time

Some jobs can be priced from photos, while others need a survey. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, the quote is fixed before anything goes ahead.

Common questions in Walworth
Can I get the Boiler Upgrade Scheme grant in Walworth?
Walworth is in England, where the Boiler Upgrade Scheme runs. The amount depends on the type of heat pump, and the survey confirms which applies. As an MCS certified installer, we apply for it on your behalf.
Do I need permission to put air conditioning in my flat in Walworth?
In many cases, yes, once the lease and the building’s rules are checked. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.
Which brands do you work with?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For new systems, we recommend a brand and model to suit the job and tell you why.
Which accreditations do you hold?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, and we’re Checkatrade members. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
Who is responsible for leak checks?
Whoever operates the equipment, together with the technicians who service it. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We can tell you which band your system falls into.
Will you work on another installer’s system?
Yes. We look at it first and tell you what we find, including anything about the original installation that needs putting right. You get a fixed price before any work goes ahead.
How long does a heat pump installation take?
A typical installation takes a few days on site, depending on the cylinder, the radiators and the pipework involved. The programme is planned to keep time without heating short, and we explain it in advance.
Heat pumps in Walworth: local notes
Valuation Office Agency council tax records show about 33% of homes in Walworth and the neighbourhoods around it were built in 2000 or later, and about 89% of households live in flats, according to the 2021 Census. Lower heat loss in recent homes often means a smaller heat pump and fewer radiator changes. A flat may have no room for a hot water cylinder, and the freeholder normally has a say on the outdoor unit, which can tip the choice towards air-to-air. London homes can be short of space for an outdoor unit and cylinder, which affects the choice of heat pump.
Homeowners near Elephant & Castle station often ask whether a heat pump can take over from the boiler, and the heat loss survey answers that. Period properties close to Lady Margaret Church can suit a heat pump, though insulation and any heritage protection are checked first.

After we’ve gone
Every system needs looking after, and most of it is easy. Our tips:
- Avoid switching the heat pump on and off often
- Leave space around the outdoor unit
- File the MCS certificate safely
Handover includes the controls and how to get the best from a heat pump. Heat pumps tend to work best running steadily rather than in short bursts, and we’ll explain the settings for your home.
Keep the outdoor unit clear of leaves, plants and stored items. Airflow is what it runs on, so keep it clear all year.
