How we handle extract fan cleaning in Tonwell
Every kitchen extract depends on its fan: it draws the air through the canopy and ductwork and pushes it outside. Whatever grease slips past the filters and duct reaches the fan, and that is what we clean. If you have hot, greasy smells near the fan and a fan shaking on its mounts, we can help.
For a kitchen in or near Tonwell, the visit is planned around opening hours and the journey, and the clean itself is the same full TR19® job as in any town: canopy to discharge, then a TR19® certificate and a photo report.
For insurers and inspectors, the record counts. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What we’re called out for in Tonwell
A fan in Tonwell builds up grease at a rate set by the kitchen, not the location: how many hours a day the kitchen runs and what it cooks. Under BESA guidance, the whole system, fan included, needs cleaning at least every 3, 6 or 12 months depending on daily hours.
Common reasons sites call us include:
- A fan that hums, whines or rumbles
- Grease stains around the discharge
- Hot, greasy smells near the fan
- A fan coated in grease inside its housing
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Aston Bury is about 4.6 miles north-west), access may need planning.

Managing agents and facilities teams in Tonwell
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 can quote for the whole system.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
What we do, step by step
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. Most of the time goes on the work itself, and that takes a couple of hours per fan, depending on its size and the build-up. Somewhere like Tonwell, lanes, gates and parking are worth mentioning in advance.
- The fan is found and its type, access and isolation checked.
- It’s isolated so it cannot run while we work.
- We scrape the heavy grease from the blades and housing.
- Blades, housing and surrounds are degreased with care around the electrics.
- It’s closed up, run, checked and photographed for the report.
How to prepare
- Make sure equipment near the work can be switched off and left to cool
- Move anything stored near the system
- Dig out any earlier paperwork for the system
How to get a quote
For a fixed quote, call 0345 646 2711 or drop us a line with the site type, your trading hours and a short description of the system. A few pictures and your last certificate or report help a lot. We typically come back within one working day.

Honest limits
An honest diagnosis matters more to us than a booking, so here’s what extract fan cleaning will not do:
- A fan that won’t start
- Grease in the duct and canopy before the fan (those need a full TR19 clean)
- A faulty speed controller or isolator
If in doubt, give us a ring on 0345 646 2711 or send us an email and we’ll say what we think.
What the work covers
- Axial fans
- Discharge points
- In-line fans
- Centrifugal fans
- Roof-mounted fans
- Fan housings
Different parts, different methods
Roof-mounted fans
Roof fans also discharge grease onto the roof around them, so the outlet area is checked too. We note any grease around the fan.
Wall fans
Wall fans often have a short duct, so grease reaches them quickly. They may need cleaning as often as the canopy, which grease readings will show.
Aftercare tips
Once we’ve finished, these simple steps help:
- Keep each photo report with the maintenance log
- Listen for new noises or vibration from the fan
- Look for grease stains near the discharge
- Check filters are seated before cooking
Once it’s clean, the fan is closed up and run to check it’s working smoothly. Anything we notice, like noise, vibration or a worn part, goes on the report, so you can plan any repair.
A change in how the fan sounds is worth noting. New noise or vibration often means grease is building on the impeller and early action can save a repair.

Should the extract fan be cleaned as part of TR19?
Yes, it should be. The whole system is cleaned, from the canopy to the discharge, and the fan sits right in that path, so it’s cleaned too.
