How the visit works
Night work is normal for us. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. The visit itself takes anything from half a day for one small unit to several shifts for a plant room full of them. If you can send photos, we can arrive in Hassell Street knowing what to expect.
- We survey the unit from photos or on site and agree what’s included.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- We clean out the drain tray and make sure it drains.
- We close up the unit and send the certificate and before and after photos.
Preparing for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Make sure someone can let us in and lock up afterwards
- Tell us where we can park and unload

Advice
How we handle AHU cleaning in Hassell Street
Heating and cooling coils trap dust that gets past the filters. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. The work covers filter sections, drain trays and heating and cooling coils, and the jobs we see most are stale or musty smells from the ventilation and air handling units with blocked filters.
Somewhere as small as Hassell Street, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Do you need AHU cleaning in Hassell Street?
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
Clients normally contact us when they notice one of these:
- Air handling units with blocked filters
- Dust-coated heating and cooling coils
- Intake sections clogged with outdoor debris
- Plant that needs cleaning after a refit
If you manage a school such as Wye School, ventilation cleaning is best booked for the holidays.
Before booking anyone
- When they can work, and whether that is outside your opening hours
- What insurance they carry
- When the next visit should be, and why
- How areas they cannot reach will be recorded
Between visits
How long the results last depends on use and care. We suggest:
- Stick to the filter change plan
- Store the TR19 paperwork where auditors can find it
- Do not ignore odours coming through the grilles
- Report water on the plant room floor
Restart the unit with your site team or maintenance contractor once we’ve finished. Keep an eye on the condensate drain over the next few days to confirm water is draining away.
Do not let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
When something else is needed
A few issues sit outside what this work can do:
- Dirty ducts beyond the unit itself
- Breakdowns that need a mechanical engineer
- Building management system faults
If you’re not sure, just call 0345 646 2711 or drop us a line and we’ll give you a straight answer before you book.

How we price AHU cleaning
We quote each job individually. These are the things that affect it:
- Whether we need access equipment or extra panels
- Working hours and out-of-hours timing
- Where the site is and how we reach it
- Site requirements such as sign-in and permits
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
Helping us quote
When you call or email, these details help:
- Any symptoms, from odd noises to smells or leaks
- Your last certificate, test record or report
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any access panels or hatches you can see
To help us quote: the address, the type of site and when it’s open, a few pictures and the last certificate or report, if there is one. Once you have those, call 0345 646 2711, or send details by email.
Managing agents and facilities teams in Hassell Street
We work for landlords, managing agents and facilities managers as well as the people running the site. 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.
If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and pictures, so each one has its own record.
Your questions about AHU cleaning in Hassell Street
Can you work in Hassell Street outside opening hours?
Yes, out-of-hours work is a big part of what we do. That way a site in Hassell Street doesn’t have to lose a day’s trading. Your opening times are the first thing we ask for.
Is Hassell Street in your area for AHU cleaning?
Yes, Hassell Street is covered. Just call 0345 646 2711 or email us with a few details of the site.
What happens to the waste?
It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.
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 0345 646 2711 or drop us a line.
What if parts of the system cannot be reached?
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.
Do you need to switch the unit off?
Yes. The unit has to be shut down and isolated before it’s opened. The shutdown is planned with whoever runs the building.
Is there a report after cleaning?
Yes. You get a TR19® certificate plus before and after pictures. Keep them in the maintenance log.
What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
