Duct cleaning in Custom House
Need ductwork cleaning in Custom House? We diagnose first, fix the price and book the work around your hours, then sign off with a report and pictures.
- Grease leaking from duct joints
- A rancid smell from the extract duct
- A grease test showing the duct is overdue
What happens if it’s left?
Grease narrows the duct and slows the air. The fan works harder, the kitchen gets hotter and smoke lingers at the canopy, and grease may start to leak from joints. In Custom House, a planned overnight visit is much easier than closing unexpectedly.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you’re unsure, phone us on 0345 646 2711 or use the quote form and we will give you an honest view and a fixed quote.

Ductwork cleaning for kitchens and businesses in Custom House
The ductwork is where an extract clean is won or lost. Without enough access panels, long stretches can go years without being touched. We open up every reachable section and record any we cannot reach, so you know exactly where you stand. If you’re dealing with a duct nobody has opened in years and fat dripping from the ductwork, we can help.
Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, and the duct may run up through several floors before it discharges at the roof. In Custom House, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
Every visit ends with a written report and pictures, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Custom House kitchens: local notes
The FSA’s food hygiene register includes about 22 bars, pubs and nightclubs and about 18 hotels, B&Bs and guest houses within about 1.5 miles of central Custom House. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. The fire and rescue service for Custom House is London Fire Brigade. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. It’s Newham council that sends environmental health officers to food businesses in Custom House. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Before-and-after photos from each clean are a simple way to show the extract is in hand.
For schools such as St Joachim's Catholic Primary School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed. Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Custom House is Albert Dock Seamen's Hospital, about 0.5 miles north-east. Volunteers running a hall kitchen near St Matthew's Church, or anywhere in Custom House, may not know when the extract was last cleaned, and a grease test settles it.

Custom House questions
Who carries out food hygiene inspections in Custom House?
That is Newham council, whose environmental health officers carry out food hygiene inspections in Custom House. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Who is the fire and rescue service for Custom House?
London Fire Brigade is the fire and rescue service for Custom House. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
What types of premises do you cover?
Any commercial site with kitchens or ventilation, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
Are you insured?
Yes, fully. We also hold CHAS and SafeContractor for clients who vet their contractors.
Can you fit access panels in our ductwork?
Yes, we do. We will point out where panels are needed, and we can fit them so those sections are cleaned in future.
What information do you need?
A short description and a few pictures, with the address and opening hours. We will ask for anything else we need.
How much notice should we give?
For planned work, earlier is better, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
How the visit works
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool before we start, and floors and nearby surfaces are sheeted. On site, it takes from a few hours to more than one visit, depending on duct length and access. Night and weekend working is normal for us in London, and a site in Custom House is no exception.
- The duct route is surveyed and every access point found.
- We take grease readings along the route.
- Once the kitchen has closed, we protect the area and open the panels.
- Thick grease is scraped out, then the runs and risers are degreased.
- We close up, re-test, photograph and record anything out of reach.
Getting ready for the visit
- Move anything stored near the system
- Find the previous report, if there is one
- Let us know how we reach the system, including roofs, risers and plant rooms
Ask for a quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before work begins.
Related advice
Between visits
Aftercare is simple, and it helps at the next visit:
- Keep grease filters clean and fitted whenever you cook
- Keep to the interval on the report
- Consider fitting panels where the report shows gaps
- Leave a way through to the access panels
After the clean, the same points are tested again, giving you before and after readings. Before and after pictures sit next to the numbers.
Grease that never reaches the duct never needs cleaning out of it. Clean, properly seated filters are the duct’s best protection.
What affects the cost of ductwork cleaning
The diagnosis comes before the price. The main factors are:
- How big the system is
- Working hours and out-of-hours timing
- A single visit or a regular plan
- Site requirements such as sign-in and permits
The price reflects the work, not guesswork. That’s why every job is surveyed first, and why the quote is fixed before we start.
Helping us quote
What to send for a quote:
- The paperwork from the last visit, if you have it
- Detail shots of panels, filters and grilles
- Problems your staff have spotted
- The site address and the type of premises
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work, before we start.
How the job changes from site to site
Multi-storey and shared buildings
Ducts in taller or shared buildings often run past other occupiers. We plan access with you and the building manager, so the clean is done safely and quietly.
Vertical risers
Risers often pass through floors and walls, so fire dampers may be fitted where it crosses them. Damper testing is a separate service.
When it’s something else
We will always give you a straight diagnosis, so here’s what ductwork cleaning won’t do:
- An extract fan that has stopped working
- A damper stuck open in the duct
- Parts of the duct with no way in
Not sure which it is? You can ring 0345 646 2711 or email us and we will tell you honestly before booking.
Where we work
- Multi-storey ducts
- Vertical risers
- Attenuators
- Horizontal duct runs
