Managing agents and facilities teams in Margery
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
About our AHU cleaning in Margery
Our AHU cleaning covers sites in Margery and the rest of Surrey, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. The work covers filter sections, drain trays and heating and cooling coils, and common reasons people get in touch are intake sections clogged with outdoor debris and stale or musty smells from the ventilation.
Work in a small place like Margery starts with agreeing access and timings.
We have been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

Keeping the system healthy
So the system stays in good health:
- Make sure condensate is draining away
- Note any water around the unit or leaks below it
- Change filters on schedule and log each change
- Store the TR19 paperwork where auditors can find it
We recommend when the unit should next be inspected or cleaned, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Keep the unit’s doors and panels in working order. Sections that are awkward to open are the ones that get skipped.
What we do, step by step
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. All told, the work takes half a day to a full day per unit, with large plant planned over several shifts. Rural roads and tight entrances are worth telling us about before a visit to Margery.
- 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.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
How to prepare
- Mention any parking or loading restrictions
- Clear loose items from the work area
- Allow time for equipment near the work to be turned off and cool down
How to get a quote
Getting a quote does not take long. Call or email with a few details and you’ll usually have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
Advice
FAQs for Margery
Can you come to Margery after we close?
Yes, we can come after you close and finish before you open. The work in Margery can fit around your hours. Your opening times are the first thing we ask for.
Do you clean school ventilation in Margery in the holidays?
Yes, out-of-term visits are normal for schools. There are about 5 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Margery. Just ring 0345 646 2711, or email photos with your term dates and we’ll plan around them.
Can you quote from photos?
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.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Do you do ventilation duct cleaning too?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. Cleaning the unit and ducts together often makes sense, and we can quote for both.
How far ahead should we book?
For planned work, earlier is better, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
Are you insured?
Yes. We carry full insurance and have been trading since 2009.
Can you look after several sites?
Yes. We work across South East England and London, so we can schedule a run of sites on one programme. Each site gets its own report and pictures.

What a clean will not put right
Some problems need a different service or another trade:
- Leaking heating or cooling coils
- Building management system faults
- Dirty ducts beyond the unit itself
Not sure which it is? You can call us on 0345 646 2711 or send us an email and we will tell you honestly.
What the work covers
- Dampers and louvres
- Internal panels
- Heating and cooling coils
- Drain trays
- Filter sections
- Supply and extract fans
Why deal with it now?
Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, especially where there’s been moisture. In a small place like Margery, a system that fails can take a site out of use.
What you pay reflects the actual work. That’s why we survey first, from photos or on site, and why the quote is fixed before we start.

How we price AHU cleaning
The survey tells us what the work involves. The main factors are:
- Access, including roofs, risers and ceiling voids
- The condition we find in the survey
- One-off work versus a regular cycle
- Where the site is and how we reach it
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.
Asking for a quote
Photos and a few facts are often enough to price the work. Useful things to send:
- The postcode and the type of business
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Your opening hours and when the area is out of use
- Detail shots of panels, filters and grilles
There’s no standard price list, because every site is different. Instead, we look at your site first, from photos or a survey, and then give you a fixed quote. To start, give us a ring on 0345 646 2711, or email photos.
Signs you need AHU cleaning in Margery
Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and slime and smells soon follow.
Common reasons sites call us are:
- Dirty filters cutting the airflow
- Dirty coils holding back the airflow
- Condensate trays that won’t empty
- Dirty fans and fan housings
For schools like Kingswood Primary School, the holidays are the usual time to inspect and clean ventilation.
What to look for in a quote
- Whether the work can be done while the site is closed
- If the quote is a fixed price or an estimate
- Whether inaccessible sections are listed on the report
- If they look at the system before pricing
