AHU cleaning in Swinbrook
No two plant rooms are the same, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from pictures or a site visit, and give you a fixed quote, so you know where you stand. The work covers drain trays, filter sections and internal panels, and the jobs we see most are odours coming through the supply air and leaves and litter drawn into the unit.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What staff can safely do
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We’ll take a look and send 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.
What happens if it’s left?
A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Clearing it now is a much smaller job. With notice, the visit to Swinbrook can be fitted around your bookings and events.
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. The price is fixed before any work starts.

What the work involves, part by part
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. The intake section gets particular attention.
Filters
Filters are the first line of defence in the unit. We check them, and clean or change them as agreed in the quote, and clean the filter housing.
What affects the cost of AHU cleaning
We don’t publish a price list, because no two systems are the same. The quote depends on:
- Whether we need access equipment or extra panels
- What state the system is in
- Where the site is and how we reach it
- Site rules, permits and inductions
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are not sure what’s needed, call 0345 646 2711 or use the quote form for straight advice and a fixed quote.
Helping us quote
You don’t need the technical terms. Just send:
- Wide photos of the system and the area around it
- Any access panels or hatches you can see
- Your last certificate, test record or report
- The roof, plant room or outside wall the system runs to
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
What a clean won’t put right
AHU cleaning can’t fix everything, and we’d rather say so up front. It will not put right:
- Ductwork downstream of the unit, which is a separate clean
- Building management system faults
- Breakdowns that need a mechanical engineer
If you are not sure, just give us a ring on 0345 646 2711 or send us an email and we’ll give you a straight answer before booking.
Parts of the system we cover

Keeping the system healthy
No system stays clean for ever, but care slows the build-up. Our tips:
- Make sure the unit’s access doors open easily
- Stick to the filter change plan
- Diary the inspection date recommended in the report
- Look at the condensate drain whenever the unit is serviced
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
Swinbrook questions
Can you come to Swinbrook after we close?
Yes, out-of-hours work is a big part of what we do. That way a site in Swinbrook does not have to lose a day’s trading. Just call us on 0345 646 2711 or drop us a line with your opening times and we’ll plan around them.
Do you work in villages like Swinbrook?
Yes, Swinbrook is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
What about areas you can’t get to?
The report shows them clearly. In ductwork, new access panels are often the answer, which we can install.
How long does an AHU clean take?
Expect it to take a single shift for a typical unit, longer for large or heavily soiled ones. Size, layout and how dirty it is decide the rest, and we’ll confirm the time when we quote.
What do you clean inside the unit?
Everything inside the unit that air passes over, from intake to discharge, including coils, fan and drain trays. The photo report shows each section before and after.
How much notice should we give?
The more notice, the better, particularly for night and weekend visits. Quotes typically come back within one working day, and emergencies are covered by our 24/7 line.
What information do you need?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. Then call us on 0345 646 2711 or send us an email.
What accreditations do you have?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’re fully insured and have been trading since 2009.
