Ductwork cleaning for kitchens and businesses in Wandsworth
Duct cleaning is the hardest part of an extract clean, and the part most often skipped. Without enough access panels, long stretches can go years without being touched. Each section we can reach is cleaned, and any we can’t is written down, so you know exactly where you stand. If you have grease seeping out of the duct seams and duct runs with no cleaning record, we can help.
London kitchens tend to trade late and open early, so work in Wandsworth is normally booked for the night or the early hours. Parking, loading and access to the roof are agreed with the building before the night of the clean.
The sign-off is always in writing: a dated report with pictures of the work, 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.

How the visit works
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. We fit London jobs around the building rather than the other way round, so a visit in Wandsworth is normally out of hours.
- We map the duct route and check where the access panels are.
- We measure grease thickness at set points before cleaning.
- Access panels are opened and heavy deposits scraped out by hand.
- The duct is degreased with the method that suits the grease, from degreasers to hot water or steam.
- Post-clean readings and pictures go into the report, with any unreachable section listed.
Before we arrive
- Clear the space around the work
- Make sure equipment near the work can be switched off and left to cool
- Let us know about parking and loading
Getting a quote
We do not publish a price list, because no two systems are the same. We look at your system first, from photos or on a visit, then send a fixed quote. To get going, ring 0345 646 2711 or email us.

Grease, kitchens and Wandsworth
The Food Standards Agency lists about 81 pubs, bars and clubs and about 9 hotels and B&Bs as registered food businesses within roughly a mile and a half of the centre of Wandsworth. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. London jobs typically start after the last service, with loading and roof access agreed with the building first. Environmental health officers from Wandsworth council inspect food businesses in Wandsworth. Extraction counts as kitchen equipment, so its condition can come up on the day. A dated certificate in the maintenance file answers the question before it’s asked.
A hall kitchen that only cooks for events, whether near St Anne's Church or elsewhere in Wandsworth, still needs its extract cleaned, just less often. For schools such as St Anne's CofE Primary School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed.

FAQs for Wandsworth
Which fire authority looks after Wandsworth?
That is London Fire Brigade. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Who would carry out a food hygiene inspection at a kitchen in Wandsworth?
The local authority for Wandsworth is Wandsworth council, and its environmental health team does the inspecting. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Can you come out in an emergency?
Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we will talk you through the next steps.
How often does extract ductwork need cleaning?
It depends mostly on daily cooking hours. Kitchens cooking 12 to 16 hours a day need it at least every 3 months, while lighter use can go longer.
What types of premises do you cover?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
How long does ductwork cleaning take?
It takes from a few hours to more than one visit, depending on duct length and access. We will confirm the time when we quote.
How do you protect the area?
With sheeting and covers, before anything else happens. The work is kept contained and clean down when we finish.
What if parts of the system cannot be reached?
They’re listed in the report, never skipped quietly. You will know exactly which parts weren’t reached and why, and we can quote to improve the access.
Aftercare tips
Aftercare is simple, and it makes the next visit easier:
- Keep the fan on while anything is cooking
- Keep to the interval on the report
- File each certificate and photo report in the maintenance log
- Never cook with a filter missing
You will have a recommended date for the next clean, worked out from the grease we found and how long you cook each day, in line with BESA guidance.
Book the next duct clean before the date passes. A change in cooking hours may change the interval under BESA guidance, and grease thickness testing will show it.
What affects the cost of ductwork cleaning
The price is fixed before any work begins. It’s based on:
- The times the site is available
- How big the system is
- Parking and loading at the site
- The condition we find in the survey
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered, and you will get one fixed quote.
Asking for a quote
There’s no need for technical detail. It helps if you can send:
- Your last certificate, test record or report
- Any symptoms, from odd noises to smells or leaks
- How we’d reach plant on a roof or in a plant room
- The times we could work without disrupting the site
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.
What happens if it’s left?
Insurers know the risk of a greasy duct. Many require cleaning to TR19, and they can refuse or reduce a claim without proof. Your certificate and photo report show the ducts were cleaned. A busy site in Wandsworth builds up dirt and wear quickly, so putting it off makes the eventual job larger.
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote, and the price is fixed before work begins.

What staff can safely do
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
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, which is where we come in.
What we are called out for in Wandsworth
Grease in a duct running from a kitchen in Wandsworth is as much a fire risk as in any building. Once it lights, fire can spread along the duct and into other areas, which is why the responsible person needs it under control.
The symptoms we are asked about most are:
- A duct clean needed for an insurer
- Duct runs with no cleaning record
- Hardened, baked-on grease in long horizontal runs
- Smells of old cooking grease from the ductwork
For kitchens close to Wandsworth Town station, where the day often starts early and ends late, the extract can be cleaned overnight.
