Facilities teams in offices, schools and healthcare sites book us too across Surrey. Work can be phased by floor, building or site around the people who use them.
From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
AHU cleaning for kitchens and businesses in Windlesham
Our AHU cleans for sites in Windlesham 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. If you’re dealing with leaves and litter drawn into the unit and units that have only ever had filter changes, we can put it right.
For a building near Windlesham, the visit is planned around how it’s used, and the journey is planned ahead. The work is the same as in any town: inspect, clean, record.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What staff can safely do
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Part by part
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. We plan safe access as part of the survey, before we quote.
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. They’re cleaned using methods that will not bend or flatten the fins.
Why deal with it now?
Leave an AHU uncleaned and the dirt does not stay put. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. It’s easy to lose track of when the work was last done on a quieter site.
What you pay reflects the actual work. That’s why every job is surveyed first, and why the quote is fixed before work begins.

Fixed quotes for AHU cleaning in Windlesham
The diagnosis comes before the price. We look at:
- Site rules, permits and inductions
- Parking and loading at the site
- The times the site is available
- The condition of the system
We do not list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll explain what it covers.
What we need to know
Photos and a few facts are often enough to price the work. Useful things to send:
- Your last certificate, test record or report
- Close-ups of filters, grilles, hatches or access panels
- Where the site is and what kind of site it is
- Photos showing the whole system and its surroundings

Aftercare tips
No system stays clean for ever, but care slows the build-up. A few tips:
- Keep the certificate and photo report with the plant records
- Keep the area around the fresh air intake clear
- Make sure the unit’s access doors open easily
- Report musty smells from the vents straight away
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
What we do, step by step
Night work is normal for us. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. On site, the work takes from a few hours for a compact unit to a day or more for a large one. Around Windlesham, access is usually simpler than in a town centre, though gates and roof access are worth mentioning.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.
Preparing for the visit
- Mention any parking or loading restrictions
- Tell us about site rules, permits or sign-in
- Plan for cooking equipment or plant to be off before we arrive
Getting a quote
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before we start.

Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.
