Landlords, agents and facilities managers

Ductwork cleaning for kitchens and businesses in Bishopsgate
Every duct has its own route. Some run a short distance to an outside wall, others climb several floors to the roof. The survey traces the route, so we know where to get in and how long it will take. Common call-outs are for a rancid smell from the extract duct and grease pooling at the foot of the riser, on horizontal duct runs, attenuators and multi-storey ducts.
London kitchens tend to trade late and open early, so extract cleaning in Bishopsgate is typically done overnight, after the last service. Parking, loading and access to the roof are agreed with the building before the night of the clean.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

How the job changes from site to site
Attenuators and discharge
At the end of the duct is the discharge. It can gather grease and mark the wall or roof around it, so it’s cleaned as far as safe access allows.
Vertical risers
A riser takes the duct up through one or more floors. Grease runs down the walls and gathers at the base, so the base is one of our test points.
Honest limits
To be straight with you, some problems need a different fix:
- Duct sections that need replacing
- A failed fan motor at the end of the duct (a fan repair job)
- Fire dampers that don’t close (they need testing and remedials)
If in doubt, call us on 0345 646 2711 or send us an email and we’ll say what we think.

How it works
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. For a job in Bishopsgate, tell us about loading bays, permits, lifts and roof access when you book.
- We start by working out how the duct runs and where it can be opened.
- 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.
- We test again, take photos and note any part that couldn’t be reached.
Before we arrive
- Tell us the best time to work, such as after service or at a weekend
- Let us know about permits to work or site inductions
- Make sure someone can let us in and lock up afterwards

What your team can do, and what needs us
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Ductwork cleaning in Bishopsgate: the local picture
The FSA’s data shows about 501 pubs and bars and about 88 hotels, B&Bs and guest houses registered in and around Bishopsgate, up to about a mile and a half out. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. The fire and rescue service for Bishopsgate is London Fire Brigade. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. Most London extract cleaning happens at night, after the last service.
For schools such as The London School of Barbering, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed. Volunteers running a hall kitchen near Church of St Ethelburga, or anywhere in Bishopsgate, may not know when the extract was last cleaned, and a grease test settles it. Healthcare kitchens, like those at hospitals such as London Bridge Hospital (about 0.7 miles south), often cook for long hours, which puts them in BESA’s heavier-use bands.

Looking after it afterwards
After the visit, a few habits help the work last:
- Have the grease measured if cooking hours go up
- Leave a way through to the access panels
- Keep to the interval on the report
- Flag drips from the duct straight away
Access panels are closed and sealed back up after cleaning, and the area around them is cleaned down. Grease and dirty water are contained and removed.
Have access panels fitted where sections cannot be reached. It does not stop grease forming, but it stops it building unseen.
Your questions about ductwork cleaning in Bishopsgate
Do you work overnight in Bishopsgate?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Bishopsgate needn’t be disturbed. When you call us on 0345 646 2711 or send us an email, mention when the site is quiet.
Who would carry out a food hygiene inspection at a kitchen in Bishopsgate?

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.
Do we need to close while you work?
Not typically. Out-of-hours visits keep the disruption down. Larger jobs can be phased over several visits to keep things running.
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 shows that the ducts need a clean?
Signs include grease dripping from joints, smells and a fan working harder, but the only sure way is to measure. A WFTT or DTT reading gives a clear answer.
What’s involved in cleaning extract ducts?
We survey the route, test the grease, then open the access panels. We clean the runs and risers section by section, then the readings are repeated.
