How we handle AHU cleaning in Sedrup
Our AHU cleans for sites in Sedrup cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. We’re often asked to deal with blocked condensate drains and slimy trays and units needing a clean before a new tenant or handover, across filter sections, heating and cooling coils and drain trays.
In a village or hamlet like Sedrup, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Sedrup: your questions answered
Can you come to Sedrup after we close?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
Do you clean school ventilation in Sedrup in the holidays?
Yes, holiday work suits schools best. The FSA’s register shows about 11 schools and colleges with food registrations within roughly a mile and a half of Sedrup. Send us your term dates when you call us on 0345 646 2711 or email us, and we’ll fit the work in.
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.
Is there a survey before the work?
Yes, always. Diagnosis comes before treatment: the survey shows what needs doing and what access we need, and the quote is based on that.
What is TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.
How do you keep the site clean during the work?
With sheeting and covers, before anything else happens. The work is kept contained and clean down when we finish.
Will you repair the fan or motor?
AHU cleaning is what we offer here, not mechanical repairs. Any faults we notice are recorded for your maintenance team to follow up.
Can we book visits on a schedule?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.
How we price AHU cleaning
We quote each job individually. This is what makes a difference:
- The condition we find in the survey
- Site requirements such as sign-in and permits
- How big the system is
- How many systems or sites are involved
What you pay depends on the size of the system, the condition it’s in and access to every part of it. You get a fixed price before work begins, so you know where you stand.
What we need to know
What to send for a quote:
- The paperwork from the last visit, if you have it
- Detail shots of panels, filters and grilles
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Your opening hours and when the area is out of use
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.
Managing agents and facilities teams in Sedrup
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.

What else we do in Sedrup
What happens on the day
A visit follows the same order every time: sheeting and protection first, make the system safe, carry out the AHU cleaning, clear away and leave you the report. The visit itself takes a single shift for a typical unit, longer for large or heavily soiled ones. If the van will struggle with a lane or gateway near Sedrup, let us know and we will plan around it.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Arrange a key holder or contact on site
- Mention any sign-in, permit or induction we need
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

In-house cleaning or a specialist?
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That’s our job.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
How the job changes from site to site
Drain trays
The drain tray collects water from the cooling coil. We clear standing water, clean out slime and check the outlet is draining.
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. We clean them with care so the fins aren’t damaged.
Signs you need AHU cleaning in Sedrup
Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and slime and smells soon follow.
It’s time to book a visit if you see:
- Fan sections that haven’t been cleaned in years
- Intake sections clogged with outdoor debris
- Plant that has been serviced but not cleaned
- Odours coming through the supply air
Hospitals such as St John's Hospital (about 1.5 miles west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Sedrup are no different.
What to look for in a quote
- Whether the quote shows VAT
- Whether the figure could change on the day
- Whether they’re fully insured

Why deal with it now?
Tenants, auditors and owners may want proof that the air handling plant is kept clean. Our certificate and photo report give you clear evidence, for audits, tenants or your own peace of mind. Rural sites cannot always move to another kitchen or room when something fails.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you’re not sure what’s needed, call us on 0345 646 2711 or drop us a line and we’ll give you an honest view and a fixed quote.
