What AHU cleaning cannot fix
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- Ventilation that was badly designed in the first place
- Mechanical faults with motors, belts or bearings
- Controls and BMS settings that run the unit
If you are not sure, just give us a ring on 0345 646 2711 or drop us a line and we will give you a straight answer.
What the work covers

AHU cleaning for kitchens and businesses in Tatsfield
Our AHU cleans for sites in Tatsfield cover the parts that collect dirt: 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 internal panels, drain trays and dampers and louvres, and common reasons people get in touch are condensate trays that won’t empty and dust-coated heating and cooling coils.
London offices and flats often have ductwork added through successive refits, with old runs left behind that are hard to reach. An inspection first shows where cleaning is needed in a building in Tatsfield.
Good records are part of the job. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Managing agents and facilities teams in Tatsfield
We regularly work with managing agents. Send the address, what’s needed and how access works, and we’ll send a fixed quote.
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
Looking after it afterwards
Aftercare is simple, and it helps at the next visit:
- Note any water around the unit or leaks below it
- Clear leaves and litter away from the intake
- Do not ignore odours coming through the grilles
- Keep the certificate and photo report with the plant records
The report shows each section of the unit before and after, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.
What your team can do, and what needs us
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That is our job.
What we’re called out for in Tatsfield
Filters that are not changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. Then the rest of the unit takes the load.
Any of these means the system needs a check-up:
- Coils clogged with dust and debris
- Units that have only ever had filter changes
- Rooms that smell stuffy when the system runs
- Intake sections clogged with outdoor debris
If you run a surgery, dental practice or care home near Tatsfield, clean ventilation matters as much to you as to a hospital like Tandridge Priory (about 2.8 miles south).
Questions to ask before you book

Tatsfield: your questions answered
Do you work at weekends in Tatsfield?
Yes. We work evenings, overnight and at weekends. That way a site in Tatsfield doesn’t have to lose a day’s trading. When you give us a ring on 0345 646 2711 or drop us a line, mention when the site is quiet.
Do you offer AHU cleaning in Tatsfield?
Yes, Tatsfield is covered. Get in touch with the details and we will arrange a survey.
Are you accredited?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’ve been trading since 2009 and we are fully insured.
How much notice do you need?
For planned work, earlier is better, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
Does the AHU have to be shut down for cleaning?
Yes, while the clean is under way. Out-of-hours work is available to keep disruption down.
How do you keep the site clean during the work?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
Do you work with multi-site operators?
Yes. You deal with one contact for every site in our area, with visits on a regular schedule.
Can you quote from pictures?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Where we cannot see enough, we arrange a survey.
What happens if it’s left?
Standing water in a drain tray does not clear itself. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Clearing it now is a much smaller job. A booked night’s work in Tatsfield costs you no trading time; an unplanned closure does.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you’re not sure what’s needed, call us on 0345 646 2711 or use the quote form for straight advice and a fixed quote.

What happens on the day
The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes a single shift for a typical unit, longer for large or heavily soiled ones, and the area is cleaned down before we leave. If your building in Tatsfield has sign-in rules, permits or key holders, mention them when you book.
- 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.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
How to prepare
- Find the previous report, if there is one
- Clear the space around the work
- Mention any sign-in, permit or induction we need
How to get a quote
Here’s what helps us quote: the address, the type of site and when it’s open, a few photos and the last certificate or report, if there is one. Then ring 0345 646 2711, or send details by email.
