AHU cleaning in Wickham Bishops
Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. If you are dealing with blocked condensate drains and slimy trays and units that have only ever had filter changes, we can put it right, from supply and extract fans, heating and cooling coils and drain trays onwards.
Somewhere as small as Wickham Bishops, ducted ventilation is typically 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.
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.

Why it’s worth doing now in Wickham Bishops
A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Clearing it now is a much smaller job. With notice, the visit to Wickham Bishops can be fitted around your bookings and events.
What you pay reflects the actual work. That’s why we survey first, from pictures or on site, and why the quote is fixed before work begins.

Questions from Wickham Bishops
Do you work overnight in Wickham Bishops?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
Do you cover smaller places like Wickham Bishops?
Yes, Wickham Bishops is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
What’s included in an AHU clean?
All the internal parts the air touches, from the intake and filters through the coils and fan to the outlet. The photo report shows each section before and after.
Can you price the work without visiting?
Yes, for many jobs. Send a few wide pictures plus close-ups of panels, filters or grilles, and we normally come back within one working day. If pictures are not enough, we will survey first.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. None of it is left on site.
Can you fix a faulty AHU?
Our AHU work is cleaning rather than mechanical repair. If we spot a fault, we note it in the report so your maintenance contractor can deal with it.
Will we get paperwork for the AHU clean?
Yes, a TR19® certificate and a photo report. The report also suggests when the unit should next be inspected.
Can you come out in an emergency?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.
For landlords and multi-site operators
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we will send a fixed quote.
Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
When to call us in Wickham Bishops
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.
Keep an eye out for any of the following:
- Odours coming through the supply air
- Drain trays holding standing water
- Debris and leaves in the fresh air intake
- Filters that are clogged or overdue
In Wickham Bishops, we look inside the system before deciding what needs cleaning.

In-house cleaning or a specialist?
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
What affects the quote in Wickham Bishops
There’s no set price list, because sites vary so much. The quote depends on:
- The condition we find in the survey
- Site rules, permits and inductions
- Parking and loading at the site
- The times the site is available
You will not find a price list here, because the cost depends on the site in front of us. For a fixed quote, phone us on 0345 646 2711, or send details by email, and we’ll talk you through it.
What to send for a quote
To help us quote quickly, send us:
- Any access panels or hatches you can see
- Any previous report or certificate
- The postcode and the type of business
- A few general shots of the system
Getting a quote doesn’t take long. Send a few details and pictures, and we normally reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
