What we do, step by step
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before any work starts, and the area around the work is covered and protected. The work itself takes a single shift for a typical unit, longer for large or heavily soiled ones. Pictures of the system and its access let us plan the work in Selmeston before we set off.
- We start with a survey of the unit and a fixed quote for the work.
- We arrange the shutdown with your staff and sheet the area.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- We close up the unit and send the certificate and before and after pictures.

Advice
About our AHU cleaning in Selmeston
Our AHU cleaning covers sites in Selmeston and the rest of East Sussex, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. The work covers heating and cooling coils, supply and extract fans and drain trays, and common reasons people get in touch are plant that needs cleaning after a refit and dirty coils holding back the airflow.
In a village or hamlet like Selmeston, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Think of the report as the system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

What your team can do, and what needs us
Staff cleaning and specialist work are not the same thing. 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.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
Managing agents and facilities teams in Selmeston
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we will come back with a fixed quote.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We are happy to deal with either side, and the report can go to both.
Between visits
Simple habits between visits make a real difference. We recommend:
- Make sure condensate is draining away
- Report musty smells from the vents straight away
- Diary the inspection date recommended in the report
- Keep the area around the fresh air intake clear
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can quote for both.
Do not let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
Common problems we fix in Selmeston
An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. Then the rest of the unit takes the load.
Any of these means the system needs a check-up:
- Plant that needs cleaning after a refit
- Fan sections that haven’t been cleaned in years
- Blocked condensate drains and slimy trays
- Plant that has been serviced but not cleaned
In Selmeston, we look inside the system before deciding what needs cleaning.

Why act early in Selmeston
A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, especially where there’s been moisture. Out of sight is the usual reason a rural system goes too long without attention.
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.

What the work involves, part by part
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. The intake section gets particular attention.
Filters
Filter condition tells you a lot about the rest of the unit. We photograph them for the report.
FAQs for Selmeston
Is AHU cleaning available in Selmeston?
Yes. Our area runs across London and the South East, Selmeston included. A fixed quote normally follows within one working day of the survey details.
Will you come out to Selmeston?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
What’s TR19?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.
Can you clean without disrupting the building?
Yes. The clean is planned around when the unit can be switched off. Healthcare and care settings are planned with staff.
Where does the waste go?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. None of it is left on site.
Do you have insurance?
Yes. Full insurance covers our work, and we have been trading since 2009.
Is a quote from pictures possible?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
Do you give a certificate after the clean?
Yes. Every clean comes with a TR19® certificate and a photo report. They’re worth keeping with the plant records.
