AHU Cleaning in Tilbury
AHU cleaning for commercial sites in Tilbury and across Thurrock. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.

What your team can do, and what needs us
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
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.
AHU cleaning in Tilbury, done properly
The fan pushes every bit of air in the system, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, with the unit switched off and made safe first. The work covers heating and cooling coils, supply and extract fans and dampers and louvres, and people most often call us about air handling units with blocked filters and units that have only ever had filter changes.
In a place like Tilbury, air handling units are often tucked into roof spaces or small plant rooms, out of sight and easy to overlook. Filters, coils and drain trays need attention whatever the size of the unit.
Duct Doctor has been trading since 2009, and we’re 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 it works
On the day, we arrive 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 first, and the area around the work is covered and protected. On site, it takes one overnight shift for many single units, with bigger plant phased. For a place like Tilbury, we load the van from the survey notes so the work can be done in one visit where possible.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
Before we arrive
- Tell us where we can park and unload
- Mention any sign-in, permit or induction we need
- Find the previous report, if there is one
Getting a quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before work begins.
Advice
What affects the quote in Tilbury
The quote reflects the site in front of us. We take into account:
- The times the site is available
- How many systems or sites are involved
- Whether it’s a one-off visit or part of a schedule
- How big the system is
The price reflects the work, not guesswork. That is why we survey first, from pictures or on site, and why the quote is fixed before we start.
Helping us quote
Photos let us diagnose from a distance. The most useful are:
- Any previous report or certificate
- The times we could work without disrupting the site
- Any access panels or hatches you can see
- The roof, plant room or outside wall the system runs to
If you need AHU cleaning in Tilbury, call 0345 646 2711 or use the quote form. Tell us what kind of premises it is and when it’s open, plus photos or the previous report if they’re to hand. A fixed quote normally follows within one working day.
Leave it or put it right?
Dirt left in an air handling unit does not stay in the unit. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. Even a site near Tilbury that is only busy part of the week needs its system checked on a schedule.
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote, and the price is fixed before any work starts.

Aftercare tips
Results last longer with the right care. We suggest:
- Do not ignore odours coming through the grilles
- Make sure the unit’s access doors open easily
- Look at the condensate drain whenever the unit is serviced
- Note any water around the unit or leaks below it
When we’ve closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to make sure it stays clear.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.
Part by part
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. We note any we find in the report.
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated in agreement with the site.
Tilbury questions
Do you clean school ventilation in Tilbury in the holidays?
Yes, out-of-term visits are normal for schools. There are about 7 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Tilbury. Send us your term dates when you phone us on 0345 646 2711, or send details by email, and we’ll fit the work in.
Is Tilbury within the area you cover?
Yes, we work in villages as well as towns, and Tilbury is covered. Just mention lanes, gates or anything else about the site when you book.
Can we book visits on a schedule?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. Each report recommends when the next visit should be.
Can one contract cover all our sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together on one programme. Every site has its own report.
What types of premises do you cover?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
Can you quote from pictures?
In many cases, yes. With good pictures, the site type and your last report, we can price many jobs. Where we can’t see enough, we arrange a survey.
What do you clean inside the unit?
Everything inside the unit that air passes over, from intake to discharge, including coils, fan and drain trays. You get a photo report showing each part before and after.
How much notice should we give?
The more notice, the better, especially for out-of-hours work. Quotes usually come back within one working day, and emergencies are covered by our 24/7 line.
Tilbury buildings and their air
Going by the FSA’s register, there are about 7 schools, colleges and universities and about 9 caring premises (care homes, nurseries and hospitals) serving food across Tilbury and its immediate surroundings (about a mile and a half). Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. For Tilbury, the closest hospital is Gravesham Community Hospital, roughly 1.4 miles south. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital. We cover Tilbury, about 20 miles from central London, as part of our work across London and the South East. The visit is fixed around your opening hours, not ours.
If you manage shops or offices close to Tilbury Town station, a TR19® Air inspection shows whether the ductwork needs cleaning. School buildings such as The Gateway Academy are usually done in the holidays, so classrooms are not disturbed. Healthcare ventilation, from large hospitals like Gravesham Community Hospital (about 1.4 miles south) to small clinics, depends on clean filters, coils and ducts.

What AHU cleaning cannot fix
