Sellindge AHU cleaning
Professional AHU cleaning in and around Sellindge, timed so the site keeps working and finished with a written report and pictures.
- Dirty filters cutting the airflow
- Debris and leaves in the fresh air intake
- Units needing a clean before a new tenant or handover
How the job changes from site to site
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.
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. Anything like that is recorded with pictures.
About our AHU cleaning in Sellindge
We clean the parts of the unit where dirt and moisture gather: 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. The work covers drain trays, dampers and louvres and heating and cooling coils, and common reasons people get in touch are condensate trays that won’t empty and plant that needs cleaning after a refit.
Somewhere as small as Sellindge, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
A written report with pictures follows each visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What we are called out for in Sellindge
Filters that are not changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
Most sites get in touch after spotting something like this:
- Filters that are clogged or overdue
- Plant that has been serviced but not cleaned
- Air handling units due a clean after building work
- Rooms that smell stuffy when the system runs
Healthcare buildings such as William Harvey Hospital, about 4.7 miles north-west, depend on their ventilation; if you manage a surgery, clinic or care home near Sellindge, yours matters too.
What to look for in a quote
- Whether the whole system is included, or only the parts that are easy to reach
- How they set the interval to the next visit
- What paperwork you get at the end
- Whether inaccessible sections are listed on the report
In-house cleaning or a specialist?
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’s our job.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.

What we do, step by step
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. The visit itself takes a single shift for a typical unit, longer for large or heavily soiled ones. Somewhere like Sellindge, lanes, gates and parking are worth mentioning in advance.
- First we agree when the unit can be switched off, including evenings or weekends.
- 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.
- After pictures are taken and the certificate issued.
How to prepare
- Dig out any earlier paperwork for the system
- Mention any sign-in, permit or induction we need
- Clear the space around the work
How to get a quote

Advice
What affects the cost of AHU cleaning
A fixed price needs a few facts first. We check:
- The size of the system
- How easy every part is to reach
- One-off work versus a regular cycle
- Parking and loading at the site
The cost depends on how big the system is, the condition it’s in and access to every part of it. We give you a fixed price before any work starts, so there are no surprises.
What to send for a quote
We can often survey from pictures. The most useful are:
- Photos showing the whole system and its surroundings
- The site address and the type of premises
- Problems your staff have spotted
- Any access panels or hatches you can see
To get a fixed quote, phone us on 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We normally come back within one working day.
What AHU cleaning can’t fix
To be straight with you, some problems need a different fix:
- Coils that are corroded or leaking and need replacing
- The supply and extract ducts, quoted separately
- Airflow problems caused by the system’s design
Not sure which it is? You can call us on 0345 646 2711, or send details by email and we will tell you honestly.

Sellindge questions
Do you cover Sellindge for AHU cleaning?
Yes, Sellindge is covered. Get in touch with the details and we’ll arrange a survey.
Can you get to a site in Sellindge?
Yes. Sellindge is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.
Does the AHU have to be shut down for cleaning?
Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.
Are you fully insured?
Yes. We are fully insured, and we can share the details when you need them.
Do you do ventilation duct cleaning too?
Yes, supply and extract ducts, grilles and diffusers. The survey shows whether the ducts need cleaning now.
Will we get paperwork for the AHU clean?
Yes. Every clean comes with a TR19® certificate and a photo report. Keep them in the maintenance log.
How much notice do you need?
For planned work, earlier is better, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
What types of premises do you cover?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
Aftercare tips
To keep the system working properly between visits:
- Plan the next inspection before the last report gets filed away
- Change filters on schedule and log each change
- Flag stale or damp smells in the supply air
- Make sure condensate is draining away
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
