AHU cleaning for kitchens and businesses in St Lawrence
An AHU clean is a thorough examination and treatment of the unit. Every section is opened, cleaned and photographed, so you can see the unit’s condition for yourself. If you have condensate trays that won’t empty and debris and leaves in the fresh air intake, we can help, from drain trays, filter sections and supply and extract fans onwards.
In a smaller place like St Lawrence, buildings with ducted ventilation are more likely to be a school, a surgery, a care home or a small business unit than an office block. Even a small system collects dust in its ducts and filters.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Leave it or put it right?
Dirt left in an air handling unit doesn’t stay in the unit. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. Light use slows the build-up but doesn’t stop it.
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.

When it’s something else
To be straight with you, some problems need a different fix:
- Breakdowns that need a mechanical engineer
- Damaged coils beyond cleaning
- A system that’s undersized for the building
Not sure which it is? You can call 0345 646 2711, or email photos and we will tell you honestly.
What the work covers
- Heating and cooling coils
- Internal panels
- Drain trays
- Supply and extract fans
- Filter sections
- Dampers and louvres
For landlords and multi-site operators
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
Keeping the system healthy
So the system stays in good health:
- Make sure condensate is draining away
- Do not store bins or materials near the intake
- Make sure the unit’s access doors open easily
- Report water on the plant room floor
If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can quote for both.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
Staff cleaning versus specialist work
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
What affects the cost of AHU cleaning
Your quote is based on your site. We take into account:
- When the work can happen, such as evenings, overnight or weekends
- How many systems or sites are involved
- How big the system is
- The condition of the system
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you’re unsure, ring 0345 646 2711 or send us an email and we’ll give you an honest view and a fixed quote.
What to send for a quote
When you call or email, these details help:
- Your last certificate, test record or report
- Close-ups of filters, grilles, hatches or access panels
- How we’d reach plant on a roof or in a plant room
- Problems your staff have spotted
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.
What we do, step by step
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. The middle part takes longest, which takes a single shift for a typical unit, longer for large or heavily soiled ones. Tell us when your site near St Lawrence is quiet and the visit will be booked for then.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Let us know about permits to work or site inductions
- Dig out any earlier paperwork for the system
- Let us know when the site is closed or quiet
Getting a quote
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work, before work begins.

Do you give a certificate after the clean?
Yes, a TR19® certificate and a photo report. The report also suggests when the unit should next be inspected.
How do you keep the site clean during the work?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
Can we book visits on a schedule?
Yes. Tell us what you have and how it’s used, and we will suggest a schedule and quote for it.
Do you survey before quoting?
Yes. For many sites, pictures and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
What happens if you can’t reach some of it?
We record them on the report, with a note of where it is, and we explain what access is needed, such as extra access panels in ductwork.
What do you clean inside the unit?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. What happens to the filters is agreed when we quote.
