About our AHU cleaning in Harwich
Drain trays under cooling coils are meant to empty. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. We’re often asked to deal with dust-coated heating and cooling coils and filters that are clogged or overdue, across drain trays, internal panels and filter sections.
For a school, surgery or office in Harwich, cleaning is planned around opening hours: evenings, weekends or school holidays.
The sign-off is always in writing: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Your questions about AHU cleaning in Harwich
Can the work in Harwich be done at night or at weekends?
Yes, nights and weekends are routine for us. That way a site in Harwich does not have to lose a day’s trading. Let us know the hours you are closed and we’ll book within them.
Do you do school ventilation cleaning in Harwich in the summer holidays?
Yes, and it’s the easiest time to do it. With about 10 schools and colleges on the FSA’s register within roughly a mile and a half of Harwich, it pays to plan holiday dates ahead. Send us your term dates when you ring 0345 646 2711, or send details by email, and we’ll fit the work in.
Will we get paperwork for the AHU clean?
Yes. Every clean comes with a TR19® certificate and a photo report. They’re worth keeping with the plant records.
Which kinds of sites do you work on?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
What does AHU cleaning cost?
Every site is different, so each gets its own fixed quote. For a quote, give us a ring on 0345 646 2711, or email photos with the site type, opening hours and a few photos.
Is Harwich in your area?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, Harwich included.
Do you clean the ductwork as well?
Yes. Ductwork is cleaned through access panels, and any sections we cannot reach are noted in the report, and new panels can be fitted.
What does TR19 mean?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t law, but it’s the benchmark.
What happens on the day
The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes anything from half a day for one small unit to several shifts for a plant room full of them, and we clear up before we go. Three things shape a visit in Harwich: when you’re closed, where we can park and how we get to the system.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
Before we arrive
- Make sure equipment near the work can be switched off and left to cool
- Name a contact who can let us in at the agreed time
- Clear loose items from the work area
Getting a quote
Every quote begins with a look at the system, from your pictures and details or, where that is not enough, a survey on site. Then we send a fixed price, before work begins.

What else we do in Harwich
Harwich buildings and their air
Food Standards Agency records list about 10 schools, colleges and universities, about 8 caring premises (care homes, nurseries and hospitals) and about 3 hotels and B&Bs registered as food businesses within 1.5 miles or so of the middle of Harwich. Busy, occupied buildings like these are where clean supply air matters most. About 4.5 miles north-east of Harwich is Felixstowe Community Hospital, the nearest hospital. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital.
If you manage a school such as Harwich and Dovercourt High School, ventilation cleaning is best booked for the holidays. If you run an office near Dovercourt station, its supply ductwork can gather dust for years before anyone looks inside. Hospitals such as Felixstowe Community Hospital (about 4.5 miles north-east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Harwich are no different.

What’s near Harwich
Locally, jobs take us to businesses close to St Joseph's Catholic Primary School and The Trafalgar Public House and the streets around them. For rail, the closest station is Dovercourt station, about 0.9 miles north-east. Well-known places in the area include Landguard Fort (2.5 miles east) and Harwich Museum (1.3 miles north-east).

What staff can safely do
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Aftercare tips
To keep the system working properly between visits:
- Keep filter changes on time and recorded
- Keep the certificate and photo report with the plant records
- Make sure the unit’s access doors open easily
- Book the next check in line with the report
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
What the work involves, part by part
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. We clean the coil and the tray beneath it together.
Drain trays
Standing water in a tray sits right where the air passes. We clean it and note if the slope or the drain needs attention.
For landlords and multi-site operators
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 can quote for the whole system.
Records are where multi-site compliance often slips. Every visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
Fixed quotes for AHU cleaning in Harwich
Every site gets its own quote. This is what makes a difference:
- One-off work versus a regular cycle
- The condition we find in the survey
- Site rules, permits and inductions
- The size of the system

What we need to know
Photos let us diagnose from a distance. The most useful are:

- When the site is open and when it’s quiet
- Photos showing the whole system and its surroundings
- Detail shots of panels, filters and grilles

What a clean won’t put right
A few issues sit outside what this work can do:
