Kitchen extracts in Adelphi
Food Standards Agency records list about 4,261 restaurants, cafés and canteens and about 749 sandwich bars and takeaways within roughly a mile and a half of the centre of Adelphi. Behind every canopy among them is a run of ductwork that collects grease out of sight. Adelphi sits within the area of 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. Overnight is the normal time to clean a London kitchen extract, so trading is not affected.
Volunteers running a hall kitchen near Savoy Chapel, or anywhere in Adelphi, may not know when the extract was last cleaned, and a grease test settles it. Healthcare kitchens, like those at hospitals such as Savoy Hospital (about less than half a mile north-east), often cook for long hours, which puts them in BESA’s heavier-use bands.

Ductwork cleaning in Adelphi, done properly
Between the canopy and the fan runs the ductwork, hidden above ceilings and inside walls. Every horizontal run and vertical riser collects grease along the way and a fire in the duct can spread through the building. We clean it from the inside, through access panels, to BESA TR19® Grease. The work covers multi-storey ducts, access panels and attenuators, and people most often call us about grease seeping out of the duct seams and gaps where access panels were never fitted.
In a London area like Adelphi, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. Grease in a duct like that is a fire risk to the whole building, not just the kitchen, so a regular TR19® clean protects everyone in it.
Nothing is signed off by word of mouth: a dated report with photos 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.

What else we do in Adelphi
Why it’s worth doing now in Adelphi
Under BESA guidance, the mean grease level should stay at or below 200 microns between cleans. Anywhere that reaches 500 microns or more needs immediate spot cleaning. Putting off the clean only pushes readings higher. Choosing the date yourself beats having a fault choose it for you.
The cost depends on how big the system is, the condition it’s in and access to every part of it. You get a fixed price before work begins, so there are no surprises.
Why book with us
- Out-of-hours work and a 24/7 emergency line
- Ventilation hygiene specialists since 2009
- Fixed quotes, typically within one working day
- One number for every site across the South East and London
Landlords, agents and facilities managers
Facilities teams in offices, schools and healthcare sites book us too across Greater London. Larger estates can be phased building by building around the people who use them.
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
What a clean will not put right
An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:
- Ductwork that’s corroded, split or holed (that needs a ductwork contractor)
- Fire dampers that do not close (they need testing and remedials)
- Sections that can’t be reached safely without new access (those are recorded, and panels can be fitted)
Not sure which it is? You can call us on 0345 646 2711 or use the quote form and we’ll tell you honestly before booking.
Where we work
- Attenuators
- Access panels
- Vertical risers
- Bends and junctions
- Horizontal duct runs
- Multi-storey ducts
In-house cleaning or a specialist?
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
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, which is where we come in.
Adelphi questions
Who inspects food businesses in Adelphi?
Kitchens in Adelphi are inspected by Westminster council’s environmental health officers. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Does London parking affect a job in Adelphi?
A loading bay, a visitor permit or off-street space near the site in Adelphi makes the visit easier to plan. Where restrictions apply in the day, an evening or overnight visit typically gets round them.
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 as one programme. Every site has its own report.
How long does it take to clean extract ducts?
Allow a shift or more, depending on the length of the runs and the number of access points. We’ll confirm the time when we quote.
What if part of the duct can’t be reached?
Sections out of reach are written down on the report, as TR19 expects. New panels can be fitted to reach them in future.
What does TR19 mean?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line for anything that cannot wait until a planned visit. Ring any time and tell us what’s happened.
What should I send you?
A short description and a few pictures, with the address and opening hours. We’ll ask for anything else we need.
Keeping the system healthy
After the visit, a few habits help the work last:
- Do not switch the extract off early
- Ask us about extra access panels where sections can’t be reached
- Check readings when the menu changes
- Keep grease filters clean and fitted whenever you cook
Keep the certificate and report with the fire risk assessment. It’s the evidence an insurer or inspector may ask for, and the photos make the duct’s condition easy to see.
Watch for warning signs between cleans: grease leaking from duct joints, smells, or a fan that sounds rough. A grease thickness test can confirm whether a spot clean is needed.
Signs you need ductwork cleaning in Adelphi
Many ducts do not have enough access panels. Stretches with no way in may never have been touched, and the grease there keeps building out of sight.
What we’re most often called out for:
- High readings at a recent grease test
- An insurer asking for TR19 evidence
- Duct runs that can’t be reached
- Thick deposits at the bottom of a vertical duct
Commuter trade near London Charing Cross station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.
What to look for in a quote
- Exactly which parts of the system are covered
- Whether inaccessible sections are listed on the report
- If the quote is a fixed price or an estimate
- Whether a written report and pictures are included
How it works
When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. From there, it takes a shift or more, depending on the length of the runs and the number of access points. Expect the work in Adelphi to happen after your last customer leaves, not during trading.
- First we diagnose: the route, the access and the grease levels.
- A fixed quote follows, based on what we found.
- Each section is cleaned in turn through its access panel.
- We take extra care at bends and at the foot of risers.
- The duct is signed off with readings, pictures and a next clean date.
Getting ready for the visit
- Let us know about permits to work or site inductions
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Let us know about parking and loading
Get a fixed quote
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.
