AHU cleaning for kitchens and businesses in Old Dean
No two plant rooms are the same, from a small ceiling-mounted unit to a large rooftop plant. Every job starts with a survey, from pictures or on site, followed by a fixed quote before any cleaning starts. We’re often asked to deal with dirty filters cutting the airflow and dirty coils holding back the airflow, across dampers and louvres, filter sections and drain trays.
Visits to a place like Old Dean are fitted around opening hours. The method does not change: inspect first, clean, then record what was done.
We’ve been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

Questions from Old Dean
Can the work in Old Dean be done at night or at weekends?
Yes, we can come after you close and finish before you open. The work in Old Dean can fit around your hours. Your opening times are the first thing we ask for.
Do you do school ventilation cleaning in Old Dean in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. Food Standards Agency records list about 16 schools, colleges and universities with registered kitchens within about a mile and a half of Old Dean. Just call 0345 646 2711 or drop us a line with your term dates and we will plan around them.
When should our AHU next be cleaned?
There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and the report recommends a next date.
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.
Does the AHU have to be shut down for cleaning?
Yes. The unit has to be shut down and isolated before it’s opened. We agree the timing with your site team.
How long will the unit be out of action?
Cleaning takes a single shift for a typical unit, longer for large or heavily soiled ones. Large plant can be split over several shifts, so give us a ring on 0345 646 2711, or send details by email to talk it through.
Do you survey before quoting?
Yes. For many sites, photos and a few details are enough, and larger or hidden systems get a visit.
Do you have a 24/7 line?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.

Managing agents and facilities teams in Old Dean
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
Facilities teams in offices, schools and healthcare sites book us too in Old Dean and across Surrey. Work can be phased by floor, building or site to keep disruption down.
How the visit works
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, and the sign-off is a written report with photos. Most of the time goes on the work itself, which takes one overnight shift for many single units, with bigger plant phased. Tell us when your site near Old Dean 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.
How to prepare
- Find the previous report, if there is one
- Mention any sign-in, permit or induction we need
- Plan for cooking equipment or plant to be off before we arrive

Related advice
Part by part
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. The impeller, its housing and the fan chamber are cleaned.
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. We clean them with care so the fins aren’t damaged.
Ventilation in Old Dean buildings
Food Standards Agency data includes about 16 schools, colleges and universities and about 10 care, childcare and hospital premises in Old Dean and the streets around it, up to about 1.5 miles out. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Frimley Park Hospital is the nearest hospital, about 2.4 miles south-west of Old Dean. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. Old Dean is about 29 miles from central London, well within the area we cover across London and the South East. A survey and a fixed quote come first, then the visit at a time that suits you.
If you run a surgery, dental practice or care home near Old Dean, clean ventilation matters as much to you as to a hospital like Frimley Park Hospital (about 2.4 miles south-west).

The nearest railway station is Camberley station, roughly 1.5 miles south-west of the centre. A little further out are Frimley Park Hospital (2.4 miles south-west) and Surrey Heath Museum (1.4 miles south-west). For a walk, there’s Heath Lake and Wildmoor Heath.
Staff cleaning versus specialist work
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.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
What we are called out for in Old Dean
Planned maintenance often covers belts, motors and filters but not cleaning. So a unit can be well maintained and still dirty.
What we are most often called out for:
- Dirty filters cutting the airflow
- Dirty fans and fan housings
- Stale or musty smells from the ventilation
- Intake sections clogged with outdoor debris
For schools like Collingwood College, the holidays are the usual time to inspect and clean ventilation.
What to look for in a quote
- Whether the figure could change on the day
- Whether they’re fully insured
- How areas they can’t reach will be recorded
- What paperwork you get at the end
What happens if it’s left?
Stuffy rooms and stale smells in a building in Old Dean can sometimes be traced back to the AHU. A clean tackles the source instead of masking it. Booking now means the visit to Old Dean is planned around you, not forced by a breakdown.
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before work begins.

How we price AHU cleaning
Every site gets its own quote. This is what makes a difference:
- A single visit or a regular plan
- The number of sites or systems
- Whether we need access equipment or extra panels
- Travel, parking and unloading
What you pay reflects the actual work. That’s why every job is surveyed first, and why the quote is fixed before any work starts.
Asking for a quote
When you call or email, it’s useful to have:
- Wide pictures of the system and the area around it
- The postcode and the type of business
- Your last certificate, test record or report
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Getting a quote does not take long. Send a few details and pictures, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
