How we handle AHU cleaning in Drayton
Our AHU cleans for sites in Drayton 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. Typical jobs include air handling units never cleaned inside and dust built up on fan impellers, on supply and extract fans, internal panels and filter sections.
Visits to a place like Drayton are fitted around opening hours. The work is the same as in any town: inspect, clean, record.
Each visit ends with a written report and photos, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Drayton: your questions answered
Do you work overnight in Drayton?
Yes. We work evenings, overnight and at weekends. The work in Drayton can fit around your hours. When you phone us on 0345 646 2711 or drop us a line, mention when the site is quiet.
Can ventilation in schools around Drayton be cleaned out of term?
Yes, out-of-term visits are normal for schools. With about 12 schools and colleges on the FSA’s register within roughly a mile and a half of Drayton, it pays to plan holiday dates ahead. Send us your term dates when you give us a ring on 0345 646 2711 or send us an email, and we will fit the work in.
How far ahead should we book?
Earlier is better, particularly for night and weekend visits. Quotes usually come back within one working day, and there’s a 24/7 line for emergencies.
Can you come out in an emergency?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
What happens if you can’t reach some of it?
The report shows them clearly. In ductwork, new access panels are often the answer, which we can install.
Can you price the work without visiting?
Often, yes. With good photos, the site type and your last report, we can price many jobs. Where we can’t see enough, we arrange a survey.
Which sectors do you work in?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
What happens to the waste?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. We don’t leave it behind.

Food Standards Agency data includes about 12 schools, colleges and universities, about 24 care, childcare and hospital premises and about 4 hotels and guest houses within roughly a mile and a half of the centre of Drayton. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. For Drayton, the closest hospital is Queen Alexandra Hospital, roughly 1.1 miles west. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital.

Do you need AHU cleaning in Drayton?
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and some travels further into the unit.
Signs it’s time to call us include:
- Air handling units due a clean after building work
- Dust built up on fan impellers
- Blocked condensate drains and slimy trays
- Odours coming through the supply air
If you manage a school such as Springfield School, ventilation cleaning is best booked for the holidays.

For landlords and multi-site operators
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.
Looking after it afterwards
How long the results last depends on use and care. Here’s what we suggest:
- Watch for drips or damp patches near the plant
- Check the drain tray is emptying during routine visits
- Do not store bins or materials near the intake
- Report stiff or damaged access doors
You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
How the job changes from site to site
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. We clean each section from intake to discharge.
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.

How it works
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool before work begins, and the area around the work is covered and protected. The work itself takes one overnight shift for many single units, with bigger plant phased. In a place like Drayton, we fit the visit around your hours.
- We agree a shutdown window that suits the building.
- 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.
- We take after photos and issue the certificate and report.
Getting ready for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Name a contact who can let us in at the agreed time
- Let us know about permits to work or site inductions

There’s no standard price list, because every site is different. Instead, we look at your site first, from pictures or a survey, and then give you a fixed quote. To start, phone us on 0345 646 2711 or use the quote form.
Related advice
What happens if it’s left?
Leave an AHU uncleaned and the dirt does not stay put. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. A quieter site near Drayton still needs its system looked after.
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you are unsure, give us a ring on 0345 646 2711 or drop us a line and we’ll give you an honest view and a fixed quote.

Staff cleaning versus specialist work
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.
