How we handle AHU cleaning in Roughway
Where a building in Roughway has had little more than filter changes, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full AHU clean takes in the whole unit. The work covers dampers and louvres, heating and cooling coils and internal panels, and the jobs we see most are units needing a clean before a new tenant or handover and fan sections that haven’t been cleaned in years.
Work in a small place like Roughway starts with agreeing access and timings.
Duct Doctor has 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 are fully insured.

Staff cleaning versus specialist work
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
Why it’s worth doing now in Roughway
When the unit is clean, less dirt reaches the ducts, so the whole system stays cleaner for longer. It also means the next inspection has less to find. It’s simpler to plan the work at Roughway now than to arrange it in a hurry later.
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote and give you a fixed price before we start.

Roughway buildings and their air
Roughway’s nearest hospital, Tonbridge Cottage Hospital, is about 5.6 miles south-west. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too. We cover Roughway, about 25 miles from central London, as part of our work across London and the South East. A survey and a fixed quote come first, then the visit at a time that suits you.
For schools like Hadlow Rural Community School, the holidays are the usual time to inspect and clean ventilation. Healthcare ventilation, from large hospitals like Tonbridge Cottage Hospital (about 5.6 miles south-west) to small clinics, depends on clean filters, coils and ducts.
Roughway is about 4 miles north-east of Tonbridge, in Kent. Whether your site is in the middle of Roughway or further out, AHU cleaning is available to all kinds of commercial premises, from small sites to large estates. Roughway is one of 922 places in Kent we cover for commercial clients. For sites nearby, see our Maidstone page, about 9 miles away.

Landmarks near Roughway
We work in commercial kitchens and buildings around The Kentish Rifleman Public House, among other places. The closest station to Roughway is Borough Green & Wrotham station, about 2.9 miles north. Nearby you’ll also find Hadlow Tower museum (2.1 miles south) and Ightham Court (3.3 miles north-west).
For landlords and multi-site operators
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
We also work for facilities teams across offices, schools and healthcare in Roughway and across Kent. Larger estates can be phased building by building around the people who use them.
How the job changes from site to site
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. We clean the intake and first stage of filters along with the rest.
Drain trays
Condensate from the coil drips into a tray beneath it. Standing water and slime are removed and the outlet is checked.
Roughway: your questions answered
Is Roughway within the area you cover?
Yes, smaller places are covered as well as towns. A survey first, from photos or a visit, means we arrive with the right kit.
Can you clean school ventilation in Roughway during the holidays?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 2 schools, colleges and universities with registered kitchens within about a mile and a half of Roughway. You can ring 0345 646 2711 or use the quote form with the dates the site is empty.
What accreditations do you have?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.
How long will the unit be out of action?
Expect it to take a single shift for a typical unit, longer for large or heavily soiled ones. The unit’s size and condition make the biggest difference, and the quote will give you a clear idea.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Do you give a certificate after the clean?
Yes, both a certificate and a report with photos. The report also suggests when the unit should next be inspected.
How much does AHU cleaning cost in Roughway?
We do not publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before we start.
How much notice should we give?
Book as early as you can for planned work, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
What affects the cost of AHU cleaning
We quote each job individually. This is what makes a difference:
- Where the site is and how we reach it
- One-off work versus a regular cycle
- How many systems or sites are involved
- When the work can happen, such as evenings, overnight or weekends
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you are not sure what’s needed, ring 0345 646 2711 or email us for straight advice and a fixed quote.
What we need to know
A few details help us quote accurately. When you get in touch, it helps to send:
- Any symptoms, from odd noises to smells or leaks
- Any access panels or hatches you can see
- The postcode and the type of business
- The times we could work without disrupting the site
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, before work begins.
How the visit works
The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes anything from half a day for one small unit to several shifts for a plant room full of them, and we clear up before we go. The timing of a visit to Roughway 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.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Agree a time when the area can be out of use
- Mention any parking or loading restrictions
How to get a quote
Here’s what helps us quote: where the site is, what it is and its opening hours, a few photos and the last certificate or report, if there is one. Once you have those, phone us on 0345 646 2711 or use the quote form.
