How we handle AHU cleaning in Botley
Our AHU cleans for sites in Botley cover the parts that collect dirt: the filter section, heating and cooling coils, drain trays, fan and casing. Every clean comes with a TR19® certificate and before and after photos in a report. The work covers dampers and louvres, internal panels and drain trays, and people most often call us about condensate trays that won’t empty and leaves and litter drawn into the unit.
Work in a small place like Botley starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Managing agents and facilities teams in Botley
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
Whether it’s one building or many, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with photos.

How the job changes from site to site
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. They’re cleaned using methods that won’t bend or flatten the fins.
Internal casing and panels
Dust settles on every internal surface of the unit. Each section is cleaned from the intake through to the outlet.
How we price AHU cleaning
We quote each job individually. These are the things that affect it:
- Whether several sites go on one quote
- Whether we need access equipment or extra panels
- What state the system is in
- Parking and loading at the site
What you pay depends on the size of the system, what state it’s in and access to every part of it. We give you a fixed price before any work starts, so you know where you stand.
What to send for a quote
Photos and a few facts are often enough to price the work. Useful things to send:
- Wide photos of the system and the area around it
- Any symptoms, from odd noises to smells or leaks
- Where the site is and what kind of site it is
- Any access panels or hatches you can see
To help us quote: where the site is, what it is and its opening hours, photos of the system and the last certificate or report, if there is one. Once you have those, call 0345 646 2711 or use the quote form.
FAQs for Botley
Do you clean school ventilation in Botley in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 6 schools, colleges and universities with registered kitchens within about a mile and a half of Botley. Booking early in the term gives the best choice of holiday dates.
Do you work overnight in Botley?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Botley needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Which parts of an air handling unit do you clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. What happens to the filters is agreed when we quote.
Is there a report after cleaning?
Yes. Every clean comes with a TR19® certificate and a photo report. They’re worth keeping with the plant records.
Is there a survey before the work?
Yes. We always survey first, either from photos and details you send or on a site visit. Then you get a fixed quote.
Do you offer emergency callouts?
Yes. There’s a 24/7 emergency line for anything that cannot wait until a planned visit. Call us any time and explain what’s happened.
Can you quote from pictures?
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.
Is Botley in your area?
Yes. Our technicians work in Botley, within the South East and London area we cover.
Aftercare tips
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Do not store bins or materials near the intake
- Note any water around the unit or leaks below it
- Make sure the unit’s access doors open easily
- Flag stale or damp smells in the supply air
Stick to the filter change schedule, because good filters protect everything downstream. Record each change in the maintenance log.
Make the drain tray part of every maintenance visit. A drain that is cleared early never gets to the slime stage.
What happens if it’s left?
Cleaning a unit while it only has light dust is quick. Years of build-up make the job longer and harder, particularly where damp has made it stick. In a small place like Botley, a system that fails can take a site out of use.
What you pay reflects the actual work. That is why we survey first, from photos or on site, and the price is agreed before we start.

How it works
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. Most of the time goes on the work itself, and that takes from a few hours for a compact unit to a day or more for a large one. Rural roads and tight entrances are worth telling us about before a visit to Botley.
- 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.
- A TR19® certificate and photo report follow the clean.
How to prepare
- Clear the space around the work
- Allow time for equipment near the work to be turned off and cool down
- Dig out any earlier paperwork for the system
How to get a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
