Questions from Egham Hythe
Can you clean school ventilation in Egham Hythe during the holidays?
Yes. The holidays are the usual time for school work. Around Egham Hythe, the Food Standards Agency lists about 19 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we will book the visit for when the site is empty.
Do you work at weekends in Egham Hythe?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Egham Hythe needn’t be disturbed. When you call 0345 646 2711 or send us an email, mention when the site is quiet.
Can you come out in an emergency?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
What if parts of the system cannot be reached?
They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.
Will we get paperwork for the AHU clean?
Yes. You receive a certificate and a report showing each section before and after, with any faults we noticed.
Which parts of an air handling unit do you clean?
The main parts are the filters, coils, drain tray, fan and inside of the casing. We confirm the scope after looking at the unit.
What accreditations do you have?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Do you need to switch the unit off?
Yes. The fan must be stopped and the unit isolated, and we time the work to suit the site.
How we handle AHU cleaning in Egham Hythe
An air handling unit is the heart of a building’s ventilation: 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. Typical jobs include air handling units with blocked filters and leaves and litter drawn into the unit, across dampers and louvres, drain trays and supply and extract fans.
In a smaller place like Egham Hythe, 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.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

What we do, step by step
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. The visit itself takes one overnight shift for many single units, with bigger plant phased. In a place like Egham Hythe, we fit the visit around your hours.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Standing water and slime come out of the tray and the drain is checked.
- We close up the unit and send the certificate and before and after photos.
Before we arrive
- Allow time for equipment near the work to be turned off and cool down
- Tell us the best time to work, such as after service or at a weekend
- Let us know how we reach the system, including roofs, risers and plant rooms
Ask for a quote
Photos are the quickest way to a quote: 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 many jobs can be priced from that alone.

Multi-site and managed buildings
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.
What we’re called out for in Egham Hythe
Dirt in an AHU matters in two ways: the unit supplies the air people breathe, and a dirty unit has to work harder. For the people using the building every day, that’s the air they breathe for hours on end.
Look out for these warning signs:
- Dirty fans and fan housings
- Drain trays holding standing water
- Odours coming through the supply air
- Units needing a clean before a new tenant or handover
Wherever a school like Thorpe Lea Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

When it’s something else
Some problems need a different service or another trade:
- The supply and extract ducts, quoted separately
- Damaged coils beyond cleaning
- Building management system faults
If you are not sure, just call us on 0345 646 2711, or send details by email and we will give you a straight answer before you book.

Where buildings like these have air handling units, filters, coils and drain trays need regular attention. About 19 miles out from central London, Egham Hythe is part of the South East area we work across. A survey and a fixed quote come first, then the visit at a time that suits you. Egham Hythe’s nearest hospital, Ashford Hospital, is about 2.7 miles north-east. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Ashford Hospital, about 2.7 miles north-east, is the nearest hospital to Egham Hythe, and healthcare sites of every size need their supply air kept clean.

Between visits
Results last longer with the right care. Here’s what we suggest:
- Clear leaves and litter away from the intake
- Change filters on schedule and log each change
- Report water on the plant room floor
- Make sure the unit’s access doors open easily
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
In-house cleaning or a specialist?
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
Why it’s worth doing now in Egham Hythe
Leave an AHU uncleaned and the dirt doesn’t 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. Systems on quieter sites still build up dirt and wear, just more slowly.
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will explain each part.
