Grease filter exchange for kitchens and businesses in Lewson Street
Good filters only work when they fit properly. Gaps in the filter bank are a direct route into the plenum, so we check every one at each visit. We point out any that need replacing. The work covers island canopies, mesh filters and school and hospital kitchens, and the jobs we see most are a canopy that drips grease and grease filters clogged with grease.
In a small place like Lewson Street, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
The report is your system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Signs you need grease filter exchange in Lewson Street
Wherever you are, Lewson Street included, filter washing is the job that gets skipped when the kitchen is busy. It only takes a couple of missed weeks for filters to fill with grease.
It’s time to book a visit if you see:
- Damaged filters letting grease past
- Filters that come out of the sink still dirty
- Grease building up behind the canopy filters
- Grease dripping from the canopy
Historic houses near Lewson Street, such as Belmont House and Gardens about 3.3 miles south, are a reminder that older buildings with event kitchens can have long, awkward duct routes.
Questions to ask before booking
- How areas they can’t reach will be recorded
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether VAT is included
- What insurance they carry
What the work involves, part by part
Mesh filters
Grease lodges deep in the layers of a mesh filter, so a quick rinse rarely gets it clean.
The plenum
Behind the filters sits the plenum, where air gathers before the duct. It collects whatever grease the filters miss.
Between visits
A little care between visits keeps the system in better shape. Our advice:
- Make sure no filter is left out
- Report a dripping canopy early
- Tell us if a filter is bent or damaged
- Book full TR19 cleans alongside filter changes
Your team carries on as normal, without the filter washing. Just keep the canopy clear for the next visit and let us know of any changes to opening hours.
Clean filters plus regular full cleans keep the system in good health. A maintenance plan that covers both means neither slips.
How the visit works
A visit follows the same order every time: sheeting and protection first, make the system safe, carry out the grease filter exchange, clear away and hand over the paperwork. The visit itself takes well under an hour for most canopies. If the van will struggle with a lane or gateway near Lewson Street, let us know and we will plan around it.
- 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.
- The filters are checked for fit before we go.
- We tell you if the plenum or canopy needs a clean.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Make sure equipment near the work can be switched off and left to cool
- Dig out any earlier paperwork for the system
How to get a quote
Quoting starts with a diagnosis, from your photos and details or, where that is not enough, a survey on site. Then we send a fixed price, before we start.
Related advice
Staff cleaning versus specialist work
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That’s our job.
