Grease filter exchange in Wennington
The filters in the canopy are the first thing cooking vapour meets. Their job is to stop grease getting further into the system and they do it best when they’re clean. With grease filter exchange, clean filters replace greasy ones at regular intervals. If you have grease collecting in the filter channels and poor airflow through the filters, we can put it right, from restaurants and pubs, island canopies and baffle filters onwards.
In London, few kitchens can spare a day to close, so work in Wennington 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 report is your system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Multi-site and managed buildings
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.

What your team can do, and what needs us
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
What we’re called out for in Wennington
Kitchens in Wennington, as everywhere, find filter washing slips down the list on busy weeks. A missed wash or two is all it takes for filters to fill with grease.
Any of these means the system needs a check-up:
- Grease collecting in the filter channels
- Hand-washed filters that still look greasy
- Poor airflow through the filters
- Filter washing that keeps being missed
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Rainham Hall is about 1.5 miles north-west), access may need planning.
What your quote should include
- Whether a written report and pictures are included
- When they can work, and whether that’s outside your opening hours
- Whether the quote shows VAT
- Proof of insurance
Different parts, different methods
The plenum
With good filters, less grease ends up in the plenum, but it’s still cleaned during a full TR19 clean.
Busy restaurant and pub kitchens
The more a kitchen cooks, the more grease the filters see. Changing them on time protects the ducts behind.
Leave it or put it right?
Washing filters in-house is an option for kitchens in Wennington, and it works when it’s done well and never skipped. Where it slips, an exchange service takes the job off staff. Leaving it on a busy London site only adds to the work.
We don’t list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we will talk you through it.

The process
When we arrive, we check the system against the survey or the pictures you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes a short visit, depending on how many filters the canopies hold. A name and number for whoever controls access to the building in Wennington saves time on the night.
- We look at the canopies and the condition of the filters.
- Any damaged or missing filters are noted.
- We exchange the dirty filters for a clean set.
- We check the filters are seated and the canopy is ready to use.
- We tell you if the plenum or canopy needs a clean.
How to prepare
- Let us know about parking and loading
- Clear the space around the work
- Tell us the best time to work, such as after service or at a weekend

Grease, kitchens and Wennington
Look up Wennington on the FSA’s food hygiene register and you’ll find about 23 restaurants, cafés and canteens and about 16 sandwich bars and takeaways in and around Wennington, up to about a mile and a half out. Each canopy among them has filters that load with grease and need swapping or cleaning. In London, kitchens are typically cleaned overnight, when the kitchen is closed and loading is easier. London Fire Brigade covers Wennington. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
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. If you run a church or community hall kitchen, near St Mary and St Peter's Church or elsewhere in Wennington, its extract still collects grease from every lunch and event.
Wennington is about 4 miles south of Hornchurch, in Greater London.

FAQs for Wennington
Do you work overnight in Wennington?
Yes, out-of-hours work is a big part of what we do. It means the site in Wennington keeps running as normal. Let us know the hours you’re closed and we will book within them.
Which fire and rescue service is responsible for Wennington?
It’s London Fire Brigade, which covers Wennington. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
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, and TR19® Air covers general supply and extract systems.
Who is responsible for fire safety on the premises?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: normally the employer or whoever controls the premises. Landlords, facilities managers and managing agents can also hold responsibility.
Do we need to close while you work?
Not usually. We work when the area is out of use, such as evenings, overnight, early mornings or weekends, so you keep your normal hours.
Do I get a report after the visit?
Yes. Every visit ends with a written report and photos, covering the work, any areas we couldn’t access and the recommended next date. Kitchen extract cleans to TR19® Grease also get a certificate through the BESCA Vent Hygiene Elite portal.
Can we skip TR19 cleans if the filters are changed regularly?
No. Filter exchange works between full cleans, not instead of them. A TR19® clean deals with the whole system and comes with a certificate and photo report.
Does the law say we must follow TR19?
No. TR19® itself is not law; it’s a BESA specification. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and cleaning to TR19® is the recognised way to show grease is under control.
What a clean won’t put right
An honest diagnosis matters more to us than a booking, so here’s what grease filter exchange will not do:
- Grease behind the filters that a swap cannot remove
- A canopy that does not capture the vapour properly
- Cooking smells reaching neighbours, which need odour control
If you are not sure, just give us a ring on 0345 646 2711 or email us and we’ll give you a straight answer before booking.
