About our AHU cleaning in Great Burgh
Drain trays under cooling coils are meant to empty. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Clearing and cleaning the tray is central to every AHU clean. Common call-outs are for drain trays holding standing water and units needing a clean before a new tenant or handover, on heating and cooling coils, dampers and louvres and filter sections.
In a smaller place like Great Burgh, 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. Smaller systems still gather dust and need inspecting.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What staff can safely do
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
What AHU cleaning looks like in Great Burgh
There are about 9 schools, colleges and universities and about 20 hospitals, care homes and childcare premises on the FSA’s food hygiene register within about 1.5 miles of central Great Burgh. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Great Burgh, about 14 miles from central London, is within our usual area. Evening, overnight and weekend visits are all possible. About 1.9 miles north-west of Great Burgh is Epsom General Hospital, the nearest hospital. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
Wherever a school like Shawley Community Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time. If you run a surgery, dental practice or care home near Great Burgh, clean ventilation matters as much to you as to a hospital like Epsom General Hospital (about 1.9 miles north-west).
Great Burgh is about 2 miles south-east of Epsom, in Surrey.

What affects the quote in Great Burgh
The quote reflects the site in front of us. We take into account:
- The scale of the work
- Site rules, permits and inductions
- A single visit or a regular plan
- Travel, parking and unloading
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll explain each part.
Helping us quote
You don’t need the technical terms. It helps if you can send:
- Wide photos of the system and the area around it
- The roof, plant room or outside wall the system runs to
- Where the site is and what kind of site it is
- Your last certificate, test record or report
Here’s what helps us quote: the address, the type of site and when it’s open, pictures of the system and any previous report or certificate. Then call us on 0345 646 2711, or send details by email.
Your questions about AHU cleaning in Great Burgh
Do you work in villages like Great Burgh?
Yes, Great Burgh is part of our area, however small the site. A survey first, from pictures or a visit, means we arrive with the right kit.
Can the work in Great Burgh be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Great Burgh needn’t be disturbed. Just call 0345 646 2711 or drop us a line with your opening times and we’ll plan around them.
Can you look after several sites?
Yes. You deal with one contact for every site in our area, with visits on a regular schedule.
Which accreditations do you hold?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
How long does it take to clean an air handling unit?
As a guide, it takes a single shift for a typical unit, longer for large or heavily soiled ones. The shutdown is planned to fit, including evenings or weekends.
Does the AHU have to be shut down for cleaning?
Yes. Cleaning needs the unit off and isolated, and we time the work to suit the site.
What do you do with what you remove?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. None of it is left on site.
Can you fix a faulty AHU?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We’ll flag anything we notice during the clean.
How the visit works
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool before any work starts, and the area around the work is covered and protected. The work itself takes anything from half a day for one small unit to several shifts for a plant room full of them. A site near Great Burgh normally has room to park, so the questions are about access to the system and your hours.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
How to prepare
- Mention any parking or loading restrictions
- Plan for cooking equipment or plant to be off before we arrive
- Move anything stored near the system

Do you need AHU cleaning in Great Burgh?
Planned maintenance often covers belts, motors and filters but not cleaning. That means a unit can tick every service box and still be carrying years of dirt.
What we’re most often called out for:
- Intake sections clogged with outdoor debris
- Air handling units never cleaned inside
- Filters that are clogged or overdue
- Odours coming through the supply air
Workplaces around Tattenham Corner station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.
What to look for in a quote
- How areas they can’t reach will be recorded
- Whether a survey comes first
- Which accreditations they hold, and whether you can check them
- Whether VAT is included
How the job changes from site to site
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. We note any we find in the report.
Filters
Dirty filters cut airflow and let dirt slip past their frames. The filter section is cleaned so new or cleaned filters sit properly.
Managing agents and facilities teams in Great Burgh
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
Why act early in Great Burgh
Facilities teams are often asked for evidence that the ventilation is looked after. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. When a site near Great Burgh shuts unexpectedly, the people who rely on it notice at once.
