AHU cleaning in Shopwyke, done properly
Our AHU cleans for sites in Shopwyke cover the parts that collect dirt: the filter section, heating and cooling coils, drain trays, fan and casing. Every clean comes with a TR19® certificate and before and after photos in a report. The work covers dampers and louvres, internal panels and heating and cooling coils, and the jobs we see most are filters that are clogged or overdue and air handling units never cleaned inside.
In a village or hamlet like Shopwyke, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

Looking after it afterwards
Once we have finished, these simple steps help:
- Book the next check in line with the report
- Store the TR19 paperwork where auditors can find it
- Report stiff or damaged access doors
- Do not store bins or materials near the intake
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
When something else is needed
An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:
- Breakdowns that need a mechanical engineer
- Controls and BMS settings that run the unit
- A system that is undersized for the building
If in doubt, phone us on 0345 646 2711, or email photos and we will say what we think before you book.

In-house cleaning or a specialist?
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. The inside of ducts and units needs a specialist.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
Shopwyke: your questions answered
Do you do school ventilation cleaning in Shopwyke in the summer holidays?
Yes, out-of-term visits are normal for schools. With about 6 schools and colleges on the FSA’s register within roughly a mile and a half of Shopwyke, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.
Do you work overnight in Shopwyke?
Yes, evening, overnight and weekend work is normal for us. The work in Shopwyke can fit around your hours. Tell us your opening hours when you ask for a quote.
What is TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
Do you give a certificate after the clean?
Yes. You receive a certificate and a report showing each section before and after, including anything we think needs attention.
How much notice do you need?
For planned work, earlier is better, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
How do you keep the site clean during the work?
Protection goes down first: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
Can we book visits on a schedule?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
Which parts of an air handling unit do you clean?
Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.
The process
We start by comparing what we find with the survey or your photos. Anything unexpected is raised with you before we go further. After that, the work takes from a few hours for a compact unit to a day or more for a large one. If the van will struggle with a lane or gateway near Shopwyke, let us know and we’ll plan around it.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Clear loose items from the work area
- Make sure someone can let us in and lock up afterwards
- Mention any sign-in, permit or induction we need
How to get a quote
For a fixed quote, phone us on 0345 646 2711 or email us and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We typically come back within one working day.

Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
What the work involves, part by part
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. As part of the clean, filters are checked and cleaned or replaced as agreed, and clean the filter housing.
Drain trays
Drain trays can rust and leak over time. Their condition goes into the report with pictures so you can decide on any repairs.
