AHU cleaning in Dawesgreen
Our AHU cleaning covers sites in Dawesgreen and the rest of Surrey, in offices, schools, hospitals, care homes and retail. Units are cleaned when the site can spare them, often evenings, overnight or weekends. If you’re dealing with leaves and litter drawn into the unit and dirty filters cutting the airflow, we can put it right, from supply and extract fans, internal panels and heating and cooling coils onwards.
For a building in or near Dawesgreen, access is agreed in advance and the visit is planned around the journey.
A written report with photos follows every visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Dawesgreen questions
Do you clean school ventilation in Dawesgreen in the holidays?
Yes, out-of-term visits are normal for schools. With about 2 schools and colleges on the FSA’s register within roughly a mile and a half of Dawesgreen, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.
Can you get to a site in Dawesgreen?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
What do you do with what you remove?
We take it away when we go. During the work, it’s contained so the area stays clean.
How long does an AHU clean take?
Expect it to take half a day to a full day per unit, with large plant planned over several shifts. Size, layout and how dirty it is decide the rest, and we’ll confirm the time when we quote.
How much does AHU cleaning cost in Dawesgreen?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote and we’ll typically reply within one working day.
What information do you need?
Only a few details: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. After that, simply ring 0345 646 2711 or send us an email.
How much notice do you need?
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.
Do you give a certificate after the clean?
Yes. You get a TR19® certificate plus before and after pictures. Keep them in the maintenance log.
How the job changes from site to site
Filters
What’s on the filters is a good clue to what’s further in. We photograph them for the report.
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. The space underneath is protected with sheeting first.
Between visits
To keep the system working properly between visits:
- Clear leaves and litter away from the intake
- Check the drain tray is emptying during routine visits
- Change filters on schedule and log each change
- Plan the next inspection before the last report gets filed away
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Log every change so it’s easy to see when the next is due.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
Dawesgreen buildings and their air
About 21 miles out from central London, Dawesgreen is part of the South East area we work across. The visit is fixed around your opening hours, not ours. About 4 miles east of Dawesgreen is East Surrey Hospital, the nearest hospital. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital.
For schools like Burys Court School, the holidays are the usual time to inspect and clean ventilation.
Dawesgreen is about 3 miles south-west of Reigate, in Surrey. Anywhere in RH2, we cover AHU cleaning for commercial sites. Dawesgreen is one of 395 places in Surrey we cover for commercial clients. You can also see our page for Guildford, roughly 14 miles from Dawesgreen.
Work in RH2 is surveyed, quoted and booked the same way as anywhere else. Whether your site is on Tapner's Road and Bunce Common Road or a nearby road, we can help. If your site is just outside Dawesgreen, we cover Leigh (1 mile south-east), Bunce Common (1 mile west), Strood Green (1 mile north-west), Irons Bottom (2 miles east) and Brockham (2 miles north-west). We also work in nearby towns such as Guildford (14 miles west), Epsom (9 miles north), Horley (4 miles south-east), Redhill (4 miles north-east), Ewell (10 miles north) and Reigate (3 miles north-east).
What’s near Dawesgreen
We work in commercial kitchens and buildings around The Seven Stars Public House and the streets around them. The nearest railway station is Betchworth station, about 2.6 miles north. Well-known places in the area include East Surrey Hospital (4 miles east) and Reigate Priory Museum (2.8 miles north-east). Not far away are Reigate Heath and Colley Hill.
Why deal with it now?
A clean unit feeds cleaner air into the ductwork, so the whole system stays cleaner for longer. That makes the next inspection of a building in Dawesgreen simpler. With notice, the visit to Dawesgreen can be fitted around your bookings and events.
Working hours, access and the scale of the site all affect the cost. We take each of them into account and give you a fixed price before any work starts.

What AHU cleaning cannot fix
A few issues sit outside what this work can do:
- Mechanical faults with motors, belts or bearings
- A system that’s undersized for the building
- Ductwork downstream of the unit, which is a separate clean
Not sure which it is? You can phone us on 0345 646 2711, or email photos and we’ll tell you honestly before you book.

The process
Your staff don’t need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. The timing of a visit to Dawesgreen is set by you, and the travel is our side of the planning.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Mention any parking or loading restrictions
- Clear loose items from the work area
- Agree a time when the area can be out of use
Ask for a quote
Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price so you know the cost before any work starts.

When to call us in Dawesgreen
Most units live out of sight on roofs, in plant rooms or in ceiling voids, so they’re easy to forget about. It’s easy for a long time to go by without anyone opening the panels.
These are the problems we see most often:
- Condensate trays that will not empty
- Dust built up on fan impellers
- Odours coming through the supply air
- Dirty filters cutting the airflow
Healthcare buildings such as East Surrey Hospital, about 4 miles east, depend on their ventilation; if you manage a surgery, clinic or care home near Dawesgreen, yours matters too.
Questions to ask before booking
- When they can work, and whether that is outside your opening hours
- If they look at the system before pricing
- What happens if part of the system can’t be accessed
- When the next visit should be, and why
Staff cleaning versus specialist work
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
