AHU cleaning in Ditton, done properly
An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with pictures, so the report shows exactly what was done. We are often asked to deal with drain trays holding standing water and units that have only ever had filter changes, on internal panels, dampers and louvres and drain trays.
In a village or hamlet like Ditton, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
Each visit ends with a written report and pictures, 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.

Looking after it afterwards
Simple habits between visits make a real difference. We recommend:
- Clear leaves and litter away from the intake
- Diary the inspection date recommended in the report
- Don’t ignore odours coming through the grilles
- Report stiff or damaged access doors
Stick to the filter change schedule, because good filters protect everything downstream. Record each change in the maintenance log.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
Ditton questions
Do you work overnight in Ditton?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. When you ring 0345 646 2711, or send details by email, mention when the site is quiet.
Do you work in villages like Ditton?
Yes, Ditton is part of our area, however small the site. The journey is planned ahead, so a few details about the route help.
Are you fully insured?
Yes, fully. We also hold CHAS and SafeContractor, for sites that check contractor safety.
What about areas you cannot get to?
They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.
What accreditations do you have?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.
Do you work with multi-site operators?
Yes. One number covers all your sites in our area, with visits on a regular schedule.
Do you survey before quoting?
Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it, and the quote is based on that.
What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
Why deal with it now?
Standing water in a drain tray does not clear itself. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Dealing with it early keeps the clean straightforward. Our emergency line runs 24/7, but a planned visit to Ditton is calmer for everyone.
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at and we’ll price it together.

How it works
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. All told, the work takes from a few hours for a compact unit to a day or more for a large one. In a small place like Ditton, the journey is planned ahead and the visit arranged around the site’s hours.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Let us know how we reach the system, including roofs, risers and plant rooms
- Make sure someone can let us in and lock up afterwards

What we are called out for in Ditton
Whatever surrounds a building in Ditton, the air drawn into its AHU carries dust, pollen and debris. The intake section and first filters take the brunt, and the finer material travels on.
Keep an eye out for these warning signs:
- Dust-coated heating and cooling coils
- Dirty fans and fan housings
- Plant that has been serviced but not cleaned
- Intake sections clogged with outdoor debris
Wherever a school like Castleview Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
What your quote should include
- Whether they recommend a next date
- When they can work, and whether that is outside your opening hours
- How VAT is shown on the quote
- Proof of accreditation you can verify
What a clean won’t put right
Before you book, it helps to know what’s not included:
- The supply and extract ducts, quoted separately
- Ventilation that was badly designed in the first place
- Controls and BMS settings that run the unit
If you’re not sure, just ring 0345 646 2711 or use the quote form and we’ll give you a straight answer before booking.

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.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
