- Damaged filters letting grease past

What happens on the day
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. The visit itself takes a few minutes per canopy, longer for a large kitchen with several canopies. Somewhere like Bletchingdon, lanes, gates and parking are worth mentioning in advance.
- We record the number, size and type of your filters.
- We set the interval with you.
- The dirty set is lifted out.
- A clean set is fitted and checked for gaps.
- The dirty filters leave with us and the next visit is booked.
Preparing for the visit
- Tell us about site rules, permits or sign-in
- Make sure someone can let us in and lock up afterwards
- Dig out any earlier paperwork for the system
How to get a quote
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

Grease filter exchange in Bletchingdon
Whether your canopy has baffle or mesh filters, they load up with grease. Once they’re clogged, airflow drops and the extract struggles. Regular exchange keeps the air moving. If you’re dealing with filters that leave gaps in the canopy and staff short of time to wash filters, we can put it right.
For a kitchen in or near Bletchingdon, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What the work involves, part by part
The plenum
With good filters, less grease ends up in the plenum, but it’s still cleaned during a full TR19 clean.
Baffle filters
Baffle filters are robust and widely used in commercial canopies. They still need regular cleaning, because the grease they collect builds up.
Multi-site and managed buildings
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
Records are where multi-site compliance often slips. Every visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.
What grease filter exchange looks like in Bletchingdon
There are about 3 restaurants, cafés and works canteens across Bletchingdon and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. Each canopy among them has filters that load with grease and need swapping or cleaning. The fire and rescue service for Bletchingdon is Oxfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. In Bletchingdon, food businesses are inspected by environmental health officers from Cherwell council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A dated certificate in the maintenance file answers the question before it’s asked.
Where a hall near Church of St Giles, or anywhere in Bletchingdon, hosts lunch clubs or events, its extract gathers grease just as a café’s does. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Bicester Community Hospital is the nearest hospital to Bletchingdon, about 5.7 miles north-east. If you look after a school kitchen, at a school such as Bletchingdon Parochial Church of England Primary School or anywhere near Bletchingdon, the holidays are the usual time for a TR19® clean.

Bletchingdon: your questions answered
Can the work in Bletchingdon be done at night or at weekends?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Bletchingdon needn’t be disturbed. Let us know the hours you’re closed and we’ll book within them.
Do you cover smaller places like Bletchingdon?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
How do you protect the area?
With sheeting and covers, before anything else happens. We keep the work contained and leave the area clean.
What happens to the waste?
We take it away when we go. During the work, it’s contained so the area stays clean.
How long does grease filter exchange take?
That depends on the amount of work, but for a typical site it takes less than an hour in most kitchens. We’ll give you a better idea when we quote.
What paperwork should we keep on file?
The reports and certificates from each visit, plus your own logs. They’re what an insurer, fire officer or EHO may ask for, so keep them together and easy to find.
How far ahead should we book?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and for anything urgent, ring our 24/7 emergency line.
Who is the responsible person?
That depends on who controls the premises. The Fire Safety Order 2005 puts the duty on the responsible person, which may be the employer, owner, landlord, facilities manager or managing agent.
Looking after it afterwards
After the visit, a few habits help the work last:
- Mention it if the kitchen gets busier
- Always run the extract while cooking
- Wipe the outside of the canopy as part of daily cleaning
- Keep every filter in place during service
Once the clean filters are in, the kitchen can cook right away. The dirty set leaves with us to be cleaned.
If cooking has stepped up, the filter schedule should too. Changing the interval early stops grease building up unseen behind the canopy.
What staff can safely do
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.

Why act early in Bletchingdon

One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before work begins.

When it’s something else
We will always give you a straight diagnosis, so here’s what grease filter exchange won’t do:
- Odours from the discharge that filters won’t stop
- A canopy too small for the cooking beneath it
- Extraction problems caused by the fan rather than the filters
