AHU cleaning in Lower Slackstead
We clean the parts of the unit where dirt and moisture gather: the filter section, heating and cooling coils, drain trays, fan and casing. Every clean comes with a TR19® certificate and before and after pictures in a report. The work covers filter sections, dampers and louvres and drain trays, and people most often call us about fan sections that haven’t been cleaned in years and air handling units due a clean after building work.
Work in a small place like Lower Slackstead starts with agreeing access and timings.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Questions from Lower Slackstead
Can you work in Lower Slackstead outside opening hours?

Can you get to a site in Lower Slackstead?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
Do you work with multi-site operators?
Yes. Tell us the addresses and what each needs and you’ll get one fixed quote.
What happens if you cannot reach some of it?
We never leave them off the paperwork. You’ll know exactly which parts weren’t reached and why, along with a quote to put access in.
What is TR19?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.

Yes, of course. Tell us what you have and how it’s used and we will propose a schedule with a fixed quote.

We start with protection: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
What does AHU cleaning cost?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before we start.

What AHU cleaning can’t fix
We’d rather tell you now than book work that will not help, so here are the limits:
- Faulty motors, drives or bearings
- Leaking heating or cooling coils
- A system that’s undersized for the building
Not sure which it is? You can ring 0345 646 2711 or drop us a line and we will tell you honestly.
What the work covers
- Filter sections
- Internal panels
- Heating and cooling coils
- Drain trays
- Supply and extract fans
- Dampers and louvres
Staff cleaning versus specialist work
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
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, alongside our reports.
How it works
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. The visit takes a single shift for a typical unit, longer for large or heavily soiled ones. In a small place like Lower Slackstead, 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.
- Each section is cleaned of dust, debris and slime.
- 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
- Dig out any earlier paperwork for the system
- Mention any sign-in, permit or induction we need
- Move anything stored near the system

Looking after it afterwards
Simple habits between visits make a real difference. Our advice:
- Make sure the unit’s access doors open easily
- Note any water around the unit or leaks below it
- Plan the next inspection before the last report gets filed away
- Don’t ignore odours coming through the grilles
The report suggests a date for the next inspection or clean, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.
Why act early in Lower Slackstead

Landlords, agents and facilities managers
Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.

Do you need AHU cleaning in Lower Slackstead?
Wherever there’s a cooling coil, there’s condensate. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and that is where slime and odours start.
Clients normally contact us after spotting something like this:
- Dust-coated heating and cooling coils
- Dirty fans and fan housings
- Plant that has been serviced but not cleaned
- Blocked condensate drains and slimy trays
In Lower Slackstead, we look inside the system before deciding what needs cleaning.
