Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Southborough is about 28 miles from central London, well within the area we cover across London and the South East. The visit is fixed around your opening hours, not ours. About 1.4 miles south of Southborough is Kent and Sussex Hospital, the nearest hospital. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.

About our AHU cleaning in Southborough
Our AHU cleans for sites in Southborough cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. The work covers filter sections, internal panels and supply and extract fans, and common reasons people get in touch are debris and leaves in the fresh air intake and blocked condensate drains and slimy trays.
Smaller buildings around Southborough often keep their ventilation units in a roof void or plant cupboard, out of sight and easy to overlook. Every unit, large or small, has filters, coils and a drain tray to keep clean.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

What the work involves, part by part

Units outside are exposed to weather and windblown debris. The intake section gets particular attention.

Fixed quotes for AHU cleaning in Southborough
We quote each job individually. These are the things that affect it:
- What state the system is in
- Whether it’s a one-off visit or part of a schedule
- Whether we need access equipment or extra panels
- Where the site is and how we reach it
Whatever the type of site, the quote works 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’ll go through it with you.
Helping us quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- The site address and the type of premises
- Detail shots of panels, filters and grilles
- The times we could work without disrupting the site
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. Then we send a fixed price, before we start.
When something else is needed
AHU cleaning can’t fix everything, and we will tell you before we start. It doesn’t solve:
- Ventilation that was badly designed in the first place
- Problems with the unit’s controls or sensors
- Coils that are corroded or leaking and need replacing
Not sure which it is? You can ring 0345 646 2711 or use the quote form and we will tell you honestly before you book.
Parts of the system we cover
- Dampers and louvres
- Heating and cooling coils
- Supply and extract fans
- Filter sections
- Drain trays
- Internal panels
How it works
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. Around Southborough, access is typically simpler than in a town centre, though gates and roof access are worth mentioning.
- We survey the unit from photos or on site and agree what’s included.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
Before we arrive
- Tell us about site rules, permits or sign-in
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Name a contact who can let us in at the agreed time

Southborough questions
Do you do school ventilation cleaning in Southborough in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. With about 18 schools and colleges on the FSA’s register within roughly a mile and a half of Southborough, it pays to plan holiday dates ahead. You can call us on 0345 646 2711, or send details by email with the dates the site is empty.
Can you come to Southborough after we close?
Yes, we can come after you close and finish before you open. The work in Southborough can fit around your hours. Your opening times are the first thing we ask for.
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. Vent Hygiene Elite is run by BESCA and independently audited.
Do you cover Southborough?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, and that includes Southborough.
Which kinds of sites do you work on?
Any commercial site with kitchens or ventilation, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
How long will the unit be out of action?
Expect it to take from a few hours for a compact unit to a day or more for a large one. The unit’s size and condition make the biggest difference, and the quote will give you a clear idea.
Is there a survey before the work?
Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
What should I send you?
Some pictures and a quick description of the system, with the address and opening hours. We’ll ask for anything else we need.
What happens if it’s left?
When the unit is clean, less dirt reaches the ducts, so the ducts and grilles stay cleaner between cleans. That makes the next inspection of a building in Southborough simpler. A visit arranged in advance is far less disruptive than a callout on a busy day.
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You will have a fixed price before we start.

Signs you need AHU cleaning in Southborough
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
Most sites get in touch after spotting something like this:
- Odours coming through the supply air
- Drain trays holding standing water
- Air handling units with blocked filters
- Plant that has been serviced but not cleaned
For schools like Southborough CofE Primary School, the holidays are the usual time to inspect and clean ventilation.

In-house cleaning or a specialist?
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
