West Brompton: your questions answered
Does London parking affect a job in West Brompton?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. If the building has a loading slot system, we will book into it.
Can you clean school ventilation in West Brompton during the holidays?
Yes, and it’s the easiest time to do it. With about 76 schools and colleges on the FSA’s register within roughly a mile and a half of West Brompton, it pays to plan holiday dates ahead. Send us your term dates when you ring 0345 646 2711 or email us, and we’ll fit the work in.
Can you look after several sites?
Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Every site has its own report.
What do you need from me for a quote?
Just the basics: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. Then ring 0345 646 2711 or email us.
Do you have insurance?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
What happens if you cannot reach some of it?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
How long does it take to clean an air handling unit?
As a guide, it takes from a few hours for a compact unit to a day or more for a large one. The shutdown is planned to fit, including evenings or weekends.
What types of premises do you cover?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
AHU cleaning in West Brompton, done properly
Coils are where a lot of the dirt ends up. Dirt on the fins holds back air and makes the unit work harder to do the same job. Coils are cleaned carefully, with methods chosen so the fins are not flattened. Common call-outs are for units needing a clean before a new tenant or handover and intake sections clogged with outdoor debris, on drain trays, heating and cooling coils and filter sections.
London buildings tend to keep their plant on the roof or below ground, so work in West Brompton is often done in the evening or at weekends. Parking and loading are agreed with the building in advance.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

Why it’s worth doing now in West Brompton
A clean unit feeds cleaner air into the ductwork, so the whole system stays cleaner for longer. It also means the next inspection has less to find. A busy site in West Brompton builds up dirt and wear quickly, so putting it off makes the eventual job larger.
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.

Managing agents and facilities teams in West Brompton
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so each one has its own record.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
What affects the quote in West Brompton
We do not publish a price list, because sites vary so much. What we look at:
- Access, including roofs, risers and ceiling voids
- One-off work versus a regular cycle
- Site requirements such as sign-in and permits
- When the work can happen, such as evenings, overnight or weekends
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account and give you a fixed price before work begins.
Asking for a quote
Photos let us diagnose from a distance. Try to include:
- How we’d reach plant on a roof or in a plant room
- The postcode and the type of business
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Your opening hours and when the area is out of use
Quotes are quick. Send a few details and pictures, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
What staff can safely do
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We’ll take a look and give you a fixed quote.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Between visits
Good habits slow the build-up between visits. A few tips:
- Keep inspection doors on the unit in good order
- Watch for drips or damp patches near the plant
- Plan the next inspection before the last report gets filed away
- Keep filter changes on time and recorded
Restart the unit with your site team or maintenance contractor once we have finished. Check the drain tray is emptying over the first few days to confirm water is draining away.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.

AHU cleaning in West Brompton: local notes
Going by the FSA’s register, there are about 76 schools, colleges and universities, about 79 caring premises (care homes, nurseries and hospitals) and about 69 hotels and guest houses serving food within roughly a mile and a half of the centre of West Brompton. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. For West Brompton, the closest hospital is Western Hospital, roughly within half a mile south-west. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital. London plant rooms are often on roofs or in basements reached through occupied floors.
Classrooms and halls at schools such as St Cuthbert with St Matthias CofE Primary School are easiest to work in when pupils are away. If you run an office near West Brompton station, its supply ductwork can gather dust for years before anyone looks inside. If you run a surgery, dental practice or care home near West Brompton, clean ventilation matters as much to you as to a hospital like Western Hospital (about within half a mile south-west).

How the visit works
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes a single shift for a typical unit, longer for large or heavily soiled ones. If your building in West Brompton has sign-in rules, permits or key holders, mention them when you book.
- We start with a survey of the unit and a fixed quote for the work.
- We arrange the shutdown with your staff and sheet the area.
- Filters, coils, fan section and casing are cleaned in turn.
- Standing water and slime come out of the tray and the drain is checked.
- We close up the unit and send the certificate and before and after pictures.

Drain trays
Condensate from the coil drips into a tray beneath it. We clear standing water, clean out slime and check the outlet is draining.
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. A clean gets air moving through the coil properly again.
