Common questions in Toppesfield
Do you work overnight in Toppesfield?
Yes. We work evenings, overnight and at weekends. That way a site in Toppesfield does not have to lose a day’s trading. Just call us on 0345 646 2711, or email photos with your opening times and we’ll plan around them.
Can you get to a site in Toppesfield?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
Does the AHU have to be shut down for cleaning?
Yes, for the time we’re working on it. Out-of-hours work is available to keep disruption down.
How much notice should we give?
The more notice, the better, especially for out-of-hours work. Quotes usually come back within one working day, and there’s a 24/7 line for emergencies.
How do you protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
Do you survey before quoting?
Yes. For many sites, pictures and a few details are enough, and larger or hidden systems get a visit.
What happens to the waste?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on, so it does not spread.
What’s TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t law, but it’s the benchmark.
AHU cleaning in Toppesfield
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 photos, so you can see the unit’s condition for yourself. If you have drain trays holding standing water and plant that needs cleaning after a refit, we can put it right, from drain trays, dampers and louvres and internal panels onwards.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Multi-site and managed buildings
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side and send the paperwork to whoever needs it.
Different parts, different methods
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. We protect the area below before opening them.
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe with your site team.
Leave it or put it right?
Dirt left in an air handling unit does not stay in the unit. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. Somewhere as small as Toppesfield, losing a kitchen or building to a fault is felt by everyone who uses it.
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote, and the price is fixed before any work starts.
What you get with us
- Out-of-hours work and a 24/7 emergency line
- Every visit written up, with pictures
- One number for every site across the South East and London
- Accredited under CHAS and SafeContractor, with ISO 9001

Signs you need AHU cleaning in Toppesfield
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. The intake section and first filters take the brunt, and the finer material travels on.
If you notice any of these, it’s worth a diagnosis:
- Odours coming through the supply air
- Air handling units never cleaned inside
- Filters that are clogged or overdue
- Leaves and litter drawn into the unit
Whether the building is in Toppesfield itself or nearby, filters, coils, drain trays and ducts are all part of the work.
What your quote should include
- How VAT is shown on the quote
- What insurance they carry
- What’s included in the scope, part by part
- Whether inaccessible sections are listed on the report
The process
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Afterwards, the area is left tidy and the written report follows. In a small place like Toppesfield, the journey is planned ahead and the visit arranged around the site’s hours.
- 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.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Mention any parking or loading restrictions
- Make sure someone can let us in and lock up afterwards
- Have your last certificate or report to hand
How to get a quote
To get a fixed quote, give us a ring on 0345 646 2711, or email photos with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We normally come back within one working day.

Fixed quotes for AHU cleaning in Toppesfield

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 you will get one fixed quote.
What we need to know
You don’t need the technical terms. It helps if you can send:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Where the site is and what kind of site it is
- Close-ups of filters, grilles, hatches or access panels
- Problems your staff have spotted
Quotes are quick. Send a few details and pictures, and we normally reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
In-house cleaning or a specialist?
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
