Grease filter exchange for kitchens and businesses in Holywell
Across Holywell, our filter exchange suits restaurants, pubs, cafés, schools, care homes and other kitchens, whether there’s one canopy or many. We can come before or after service, so cooking isn’t interrupted. We’re often asked to deal with staff short of time to wash filters and grease building up behind the canopy filters, across restaurants and pubs, baffle filters and mesh filters.
In a London area like Holywell, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. A duct fire there can reach parts of the building far from the range, which is why keeping it clean to TR19® matters.
We have been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

How the job changes from site to site
The plenum
Heavy grease in the plenum often follows clogged or missing filters, or that a full clean is due.
School, care home and staff kitchens
Lighter kitchens can often go longer between changes. The interval is set to fit.
What your team can do, and what needs us
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Managing agents and facilities teams in Holywell
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
What affects the cost of grease filter exchange
We quote each job individually. These are the things that affect it:
- Parking and loading at the site
- The number of sites or systems
- What state the system is in
- Whether it’s a one-off visit or part of a schedule
What you pay reflects the actual work. That is why we survey first, from photos or on site, and the price is agreed before work begins.
What to send for a quote
To speed up the quote, please include:
- The paperwork from the last visit, if you have it
- The postcode and the type of business
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any symptoms, from odd noises to smells or leaks

What grease filter exchange looks like in Holywell
Look up Holywell on the FSA’s food hygiene register and you’ll find about 141 restaurants, cafés and works canteens and about 47 sandwich bars and takeaways within roughly a mile and a half of the centre of Holywell. Any of those kitchens with a canopy relies on its filters to catch grease before it reaches the duct. Holywell is covered by 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. Night work suits London kitchens, and roads and loading bays tend to be quieter too.
Bursars and site managers at schools such as Westfield Academy tend to book extract cleaning for when the kitchen is empty. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Watford General Hospital is the nearest hospital to Holywell, about 0.9 miles east. Where a hall near St Oswald's Parish Church, or anywhere in Holywell, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

What a clean won’t put right
A few issues sit outside what this work can do:
- Grease already built up in the ductwork, which needs a full TR19 clean
- Smell complaints that need odour control equipment
- Extraction problems caused by the fan rather than the filters

Your questions about grease filter exchange in Holywell
Do you clean school canteen extracts around Holywell out of term?
Yes, and it’s the easiest time to do it. There are about 24 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Holywell. Just give us a ring on 0345 646 2711 or use the quote form with your term dates and we will plan around them.
Can parking be tricky for a job in Holywell?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Working overnight, as we often do in London, normally makes it simpler.
Do you clean filters as well as exchanging them?
Yes. Some kitchens prefer their own filters cleaned on a schedule while others want an exchange. Either way, the canopy is not left without filters during service.
Can we skip TR19 cleans if the filters are changed regularly?
It does not. Filters don’t catch everything, so grease still reaches the ductwork and the whole system still needs its TR19 clean.
How long will you be on site?
On site, it takes less than an hour in most kitchens. Bigger or more complicated systems take longer, and the quote will say how long.
Where do the greasy filters go?
The greasy set leaves with us for cleaning and your staff do not have to deal with them. Clean filters go straight in.
Do you offer emergency callouts?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we will advise on what to do next.
How much notice do you need?
Earlier is better, particularly for night and weekend visits. Quotes normally come back within one working day, and emergencies are covered by our 24/7 line.

Between visits
Think of this as the after-treatment advice, short and simple:
- Keep the canopy clear for exchange visits
- Never leave gaps in the filter bank
- Look out for drips from the canopy
- Report damaged filters so they can be replaced
Between visits, check that every filter is still in place. A missing filter leaves a gap for grease, so let us know if one goes missing or gets damaged.
If filters are already dripping, they’re overdue. A clean set right away cuts the grease in the canopy and the plenum may need a clean as well.
The process
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes well under an hour for most canopies, and the area is cleaned down before we leave. Before any visit in Holywell, we agree where the van can stop and how equipment reaches the system.
- We count and measure the filters in every canopy.
- We agree a schedule that suits how much the kitchen cooks.
- At every visit, the greasy filters are lifted out.
- We fit clean filters and check they sit snugly in the housing.
- If a filter is damaged or the plenum needs attention, we tell you.
Getting ready for the visit
- Clear the space around the work
- Find the previous report, if there is one
- Mention any locked doors, roof access or ceiling voids
