What affects the quote in Wennington
Before we fix a price, we need to know a few things. We check:
- Whether we need access equipment or extra panels
- The scale of the work
- Where the site is and how we reach it
- A single visit or a regular plan
What you pay depends on the size of the system, the condition it’s in and access to every part of it. You get a fixed price before any work starts, so there are no surprises.
What we need to know
When you call or email, these details help:
- The site address and the type of premises
- The times we could work without disrupting the site
- A few general shots of the system
- Close-ups of filters, grilles, hatches or access panels
Getting a quote does not take long. Send a few details and photos, and we normally reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
How we handle ductwork cleaning in Wennington
Duct cleaning is the hardest part of an extract clean, and the part most often skipped. Sections with no way in can go uncleaned for years. We open up every reachable section and record any we cannot reach, so you know exactly where you stand. Typical jobs include a duct nobody has opened in years and duct runs that can’t be reached, on attenuators, bends and junctions and access panels.
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. For a kitchen in Wennington, that normally means a longer system to clean and more access panels to plan around.
Nothing is signed off by word of mouth: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Aftercare tips
Good habits slow the build-up between visits. Our tips:
- Leave a way through to the access panels
- Tell us if grease leaks from the ductwork
- File each certificate and photo report in the maintenance log
- Run the extract fan throughout service
When the duct is cleaned as part of a full TR19® Grease clean, a TR19 certificate is issued through the BESCA Vent Hygiene Elite portal. It shows when and where the clean was done and by whom.
Keep to the cleaning interval on the report. If the kitchen starts cooking longer hours, the interval may need to shorten, and grease thickness testing will show it.
What staff can safely do
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
How the job changes from site to site
Multi-storey and shared buildings
Ducts in taller or shared buildings often run past other occupiers. Access is planned with the building’s managers, so the clean is done safely and quietly.
Vertical risers
Cleaning a riser needs access along its height. Any part that can’t be safely reached is recorded.
Landlords, agents and facilities managers
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side and send the paperwork to whoever needs it.
Facilities teams in offices, schools and healthcare sites book us too in Wennington and across Greater London. Larger estates can be phased building by building around the people who use them.
Wennington kitchens: local notes
Food Standards Agency records list about 23 restaurants, cafés and works canteens and about 16 takeaways and sandwich shops within roughly a mile and a half of the centre of Wennington. Wherever those kitchens cook under a canopy, the horizontal runs and risers need cleaning as well as the hood. Wennington is covered by London Fire Brigade. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Most London extract cleaning happens at night, after the last service.
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; St George's Hospital is the nearest hospital to Wennington, about 2.8 miles north. Bursars and site managers at schools such as Brady Primary School tend to book extract cleaning for when the kitchen is empty.
Wennington is about 4 miles south of Hornchurch, in Greater London.

The process
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before work begins, and the area around the work is covered and protected. The work itself takes a shift or more, depending on the length of the runs and the number of access points. Managed blocks in London often need contractors booked in ahead, and we are happy to deal with the agent directly for a site in Wennington.
- We trace the duct and find every way in.
- 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.
- Panels are closed, readings and pictures repeated, and unreachable sections recorded.
Getting ready for the visit
- Clear the space around the work
- Tell us where we can park and unload
- Arrange a key holder or contact on site
How to get 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, the quote is fixed before any work is booked.

Your questions about ductwork cleaning in Wennington
Who inspects food businesses in Wennington?
Food hygiene inspections in Wennington are carried out by Havering council. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
What do you need to know about parking in Wennington?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Much of our London work is done overnight, which helps.
Can you look after several sites?
Yes. You deal with one contact for every site across London and the South East, with visits on a regular schedule.
What happens if you can’t reach some of it?
The report shows them clearly. In ductwork, new access panels are often the answer, which we can install.
What do you need from me for a quote?
The site address, the type of premises and your opening hours, along with a few photos and any previous report.
What types of premises do you cover?
Any commercial site with kitchens or ventilation, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
How do you protect the area?
By covering it before any work starts. The work is kept contained and leave the area clean.
Can you quote from pictures?
Usually, yes. Send a few wide photos plus close-ups of panels, filters or grilles, and we typically come back within one working day. Some sites still need a visit, and we will say so.
Common problems we fix in Wennington
Grease filters that do not seal let fat straight through. The duct then takes grease that the filters should have stopped and it fills faster.
Signs it’s time to call us include:
- Readings above 200 microns from a grease thickness test
- An insurer asking for TR19 evidence
- Years of grease along the duct floor
- Duct runs with no cleaning record
Church and community hall kitchens, near St Mary and St Peter's Church or anywhere around Wennington, are easy to forget, but their extracts collect grease like any other.
