Ventilation duct cleaning in Harwell, done properly
Everyone in the building breathes the air the ventilation brings in. Keeping the ducts clean is a sensible part of looking after them, as much as clean filters and a well-kept AHU. The work covers supply ductwork, general extract ductwork and offices and schools, and common reasons people get in touch are stuffy rooms and stale air and systems with no record of inspection or cleaning.
For a building near Harwell, the visit is planned around how it’s used, and the journey is planned ahead. The work is the same as in any town: inspect, clean, record.
The sign-off is always in writing: a written report, dated and illustrated with photos, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Questions from Harwell
Do you cover Harwell for ventilation duct cleaning?
Yes, Harwell is covered. You can call 0345 646 2711, or email photos and tell us what needs doing.
Do you cover smaller places like Harwell?
Yes, Harwell is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
Do you provide a report?
Yes, both a certificate and a photo report. It also notes unreached sections and a recommended next inspection.
What do you need from me for a quote?
The site address, the type of premises and your opening hours, along with a few photos and any previous report.
Is TR19 cleaning required by law?
No. The law sets the duty, and TR19® is the recognised benchmark for meeting it. Under the Fire Safety Order 2005, the responsible person must reduce fire risk, and many insurers can refuse or reduce a claim without proof of cleaning.
What do you do with what you remove?
It’s contained and taken away. We collect grease, debris and waste water as we go, so it does not spread.
What happens if parts of the ductwork cannot be reached?
Those sections are recorded as not cleaned in the report, with the reason. We can fit new access panels so they’re covered next time.
Do you inspect before cleaning?
Yes, on every job. We check the layout, access and condition, so the quote is fixed before any work starts.
What affects the quote in Harwell
Every site gets its own quote. These are the things that affect it:
- What state the system is in
- One-off work versus a regular cycle
- Parking and loading at the site
- How big the system is
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you’re unsure, call 0345 646 2711 or send us an email for straight advice and a fixed quote.
Asking for a quote
When you contact us, these details help:
- How we’d reach plant on a roof or in a plant room
- Detail shots of panels, filters and grilles
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Any previous report or certificate
We do not publish a price list, because every site is different. We look at your system first, from photos or on a visit, then send a fixed quote. To start, ring 0345 646 2711, or send details by email.
How it works
The first job on site is protection: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. It takes a day or less for a small system and a series of visits for a large one, and we clear up before we go. Your opening hours decide when we come to Harwell, not ours.
- We agree timings that suit the building, including evenings and weekends.
- Access panels are opened along each run.
- Before photos are taken and the ducts cleaned section by section.
- Grilles and diffusers are cleaned and refitted.
- We take after pictures and send the certificate and report.
How to prepare
- Let us know how we reach the system, including roofs, risers and plant rooms
- Make sure equipment near the work can be switched off and left to cool
- Arrange a key holder or contact on site
How to get a quote
Here’s what helps us quote: where the site is, what it is and its opening hours, a few pictures and any previous report or certificate. Once you have those, give us a ring on 0345 646 2711, or send details by email.
Advice
In-house cleaning or a specialist?
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Looking after it afterwards
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Get leaks near ductwork fixed quickly
- Keep grilles and diffusers dusted
- Switch the ventilation off or cover grilles during dusty building work
- Keep filters changed on time
The report lists the sections we cleaned and any we couldn’t reach, backed up by before and after pictures. We will suggest where new access panels would help.
Deal with condensation and leaks near ducts promptly, as moisture makes dust stick.
Multi-site and managed buildings
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so records stay tidy.
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.

Signs you need ventilation duct cleaning in Harwell
Most ductwork is out of sight, so nobody sees the build-up. The grilles get a wipe, but what’s behind them doesn’t.
Look out for any of the following:
- Rooms that feel airless when the system runs
- Odours carried round the building by the ducts
- Ductwork with too few access panels to clean
- Dusty supply ductwork that hasn’t been cleaned in years
For schools like Harwell Primary School, the holidays are the usual time to inspect and clean ventilation.
