AHU cleaning for kitchens and businesses in Broomershill
Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins are not flattened. The work covers supply and extract fans, internal panels and filter sections, and people most often call us about odours coming through the supply air and filters that are clogged or overdue.
Work in a small place like Broomershill starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Broomershill questions
Is Broomershill within the area you cover?
Yes. Broomershill is within the area we cover across London and the South East. Just mention lanes, gates or anything else about the site when you book.
Can you work in Broomershill outside opening hours?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Let us know the hours you’re closed and we will book within them.
What do you do to protect the area?
By covering it before any work starts. The work is kept contained and leave the area clean.
What about areas you cannot get to?
We never leave them off the paperwork. You’ll know exactly which parts weren’t reached and why, and we can quote to improve the access.
Can you fix a faulty AHU?
Our AHU work is cleaning rather than mechanical repair. If we spot a fault, we note it in the report for your maintenance team to follow up.
Is there a report after cleaning?
Yes. You get a TR19® certificate plus before and after photos. They’re worth keeping with the plant records.
What do you need from me for a quote?
Where the site is, what it is and when it’s open, plus photos of the system and your last certificate or report if you have one.
Are you accredited?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’ve been trading since 2009 and we’re fully insured.
What happens if it’s left?
Cleaning a unit while it only has light dust is quick. Years of build-up make the job longer and harder, particularly where damp has made it stick. If the system at a site near Broomershill fails, there may be nowhere nearby to move to.
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at, and you will get one fixed quote.

How it works
Every visit runs to the same pattern: protect the area, isolate whatever needs isolating, carry out the AHU cleaning, tidy up and hand over the paperwork. The visit itself takes half a day to a full day per unit, with large plant planned over several shifts. Somewhere as small as Broomershill, the date and timings are agreed with you well before the day.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.
Preparing for the visit
- Tell us the best time to work, such as after service or at a weekend
- Let us know about parking and loading
- Name a contact who can let us in at the agreed time
Ask for a quote
To get a fixed quote, call 0345 646 2711 or email us and tell us the type of site, your opening hours and roughly what the system looks like. A few photos and your last certificate or report help a lot. We typically come back within one working day.

Part by part
Filters
Filter condition tells you a lot about the rest of the unit. We photograph them for the report.
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. They’re cleaned using methods that will not bend or flatten the fins.
Managing agents and facilities teams in Broomershill
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 can quote for the whole system.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
Keeping the system healthy
Think of this as the after-treatment advice, short and simple:
- Flag stale or damp smells in the supply air
- Clear leaves and litter away from the intake
- Diary the inspection date recommended in the report
- Change filters on schedule and log each change
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 make sure it stays clear.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
