Essex · Air handling unit cleaning
Air handling unit cleaning in Wissington, Essex
One call covers cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces in Wissington, from survey to sign-off. CHAS and SafeContractor accredited, ISO 9001 and fully insured.
- Plant that has been serviced but not cleaned
- Dirty fans and fan housings
- Rooms that smell stuffy when the system runs
Staff cleaning versus specialist work
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. Leave those to us.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
AHU cleaning for kitchens and businesses in Wissington
Our AHU cleans for sites in Wissington cover the parts that collect dirt: the filter section, heating and cooling coils, drain trays, fan and casing. You get a TR19® certificate and a photo report showing the unit before and after. If you are dealing with condensate trays that won’t empty and dirty coils holding back the airflow, we can put it right, from heating and cooling coils, drain trays and dampers and louvres onwards.
Work in a small place like Wissington starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
For insurers and inspectors, the record counts. That is why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Landlords, agents and facilities managers
Records are where multi-site compliance often slips. Every visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.
Ventilation in Wissington buildings
There are about 3 schools, colleges and universities on the FSA’s food hygiene register within roughly a mile and a half of the centre of Wissington. Busy, occupied buildings like these are where clean supply air matters most. Severalls Hospital is the nearest hospital, about 4 miles south-east of Wissington. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. Wissington, about 52 miles from central London, is within our usual area. Visits are booked around your hours, evenings and weekends included.
Hospitals such as Severalls Hospital (about 4 miles south-east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Wissington are no different. School buildings such as Nayland Primary School are normally done in the holidays, so classrooms aren’t disturbed.

What the work involves, part by part
Drain trays
A tray that does not drain becomes a pool of stagnant water in the airstream. We clean it and report anything about the tray or drain that needs fixing.
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. Access is planned during the survey so the quote reflects it.
Looking after it afterwards
Results last longer with the right care. Here’s what we suggest:
- Report water on the plant room floor
- Clear leaves and litter away from the intake
- Stick to the filter change plan
- Look at the condensate drain whenever the unit is serviced
The report suggests a date for the next inspection or clean, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.
What affects the cost of AHU cleaning
The diagnosis comes before the price. The main factors are:
- Where the site is and how we reach it
- Working hours and out-of-hours timing
- Access, including roofs, risers and ceiling voids
- How big the system is
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you are not sure what’s needed, ring 0345 646 2711 or use the quote form and we’ll give you an honest view and a fixed quote.
What we need to know
There’s no need for technical detail. It helps if you can send:
- Any previous report or certificate
- Where the site is and what kind of site it is
- Any symptoms, from odd noises to smells or leaks
- How we’d reach plant on a roof or in a plant room
For AHU cleaning in Wissington, ring 0345 646 2711 or use the quote form. Let us know the site type and the opening hours, plus photos or the previous report if they’re to hand. A fixed quote usually follows within one working day.
Common questions in Wissington
Will you come out to Wissington?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
Can you come to Wissington after we close?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Wissington needn’t be disturbed. When you call us on 0345 646 2711 or use the quote form, mention when the site is quiet.
Will we get paperwork for the AHU clean?
Yes, a TR19® certificate and a photo report. The report also suggests when the unit should next be inspected.
Are you accredited?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We’re fully insured and have been trading since 2009.
Is there a survey before the work?
Yes. For many sites, pictures and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
Which kinds of sites do you work on?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
Can you clean the ducts connected to the AHU?
Yes. We reach the ducts through access panels, and any sections we can’t reach are noted in the report, and new panels can be fitted.
What do you do with what you remove?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
How the visit works
We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. From there, it takes a single shift for a typical unit, longer for large or heavily soiled ones. If you can send photos, we can arrive in Wissington knowing what to expect.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- We arrange the shutdown with your staff and sheet the area.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Preparing for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Agree a time when the area can be out of use
- Make sure someone can let us in and lock up afterwards
