AHU cleaning for kitchens and businesses in Reigate
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. The work covers internal panels, supply and extract fans and dampers and louvres, and people most often call us about air handling units never cleaned inside and dirty fans and fan housings.
For a school, surgery or office in Reigate, cleaning is planned around opening hours: evenings, weekends or school holidays.
We have been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

Keeping the system healthy
Good habits slow the build-up between visits. A few tips:
- Clear leaves and litter away from the intake
- Stick to the filter change plan
- File each AHU report in the maintenance log
- Watch for drips or damp patches near the plant
Stick to the filter change schedule, because good filters protect everything downstream. Record each change in the maintenance log.
Check drain trays and condensate drains during routine maintenance. A drain that’s cleared early never gets to the slime stage.

What affects the quote in Reigate
The price is fixed before any work begins. It’s based on:
- A single visit or a regular plan
- How easy every part is to reach
- Any permits to work or inductions
- The condition we find in the survey
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.
Helping us quote
A few details help us quote accurately. With your enquiry, please include:
- Any symptoms, from odd noises to smells or leaks
- When the site is open and when it’s quiet
- How we’d reach plant on a roof or in a plant room
- Where the site is and what kind of site it is
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Reigate buildings and their air
The FSA’s food hygiene register lists about 15 schools, colleges and universities and about 19 hospitals, care homes and childcare premises with registered kitchens or food service within roughly a mile and a half of the centre of Reigate. Busy, occupied buildings like these are where clean supply air matters most. East Surrey Hospital is the nearest hospital, about 2 miles south-east of Reigate. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. At about 19 miles from central London, Reigate sits well inside the area we cover. Visits are booked around your hours, evenings and weekends included.
If you run a surgery, dental practice or care home near Reigate, clean ventilation matters as much to you as to a hospital like East Surrey Hospital (about 2 miles south-east). Classrooms and halls at schools such as Reigate Priory Community Junior School are easiest to work in when pupils are away. If you manage offices or shops near Reigate station, their ventilation can be inspected and cleaned out of hours.

Different parts, different methods
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. The intake section gets particular attention.
Drain trays
Drain trays can rust and leak over time. We record their condition with pictures so repairs can be planned.
Managing agents and facilities teams in Reigate
Keeping records across a portfolio is half the battle. Each visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.
We also work for facilities teams across offices, schools and healthcare across Surrey. Larger estates can be phased building by building around the people who use them.
What happens on the day
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. All told, the work takes one overnight shift for many single units, with bigger plant phased. A few pictures of the system and its access points help us plan a visit in Reigate.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
Preparing for the visit
- Make sure equipment near the work can be switched off and left to cool
- Agree a time when the area can be out of use
- Name a contact who can let us in at the agreed time

Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before we start.

Staff cleaning versus specialist work
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
