Grease filter exchange for kitchens and businesses in Frimley
We run grease filter exchange for all kinds of kitchens in Frimley, from a single canopy to several. Visits can be timed around your service so nobody has to stop cooking. The work covers island canopies, school and hospital kitchens and mesh filters, and the jobs we see most are missing filters in the filter bank and blocked baffle filters.
Around a town like Frimley, extract cleaning usually means a restaurant, pub, takeaway or the kitchen of a school or care home. Each has a canopy, filters, ductwork and a fan to keep clear of grease, and each is cleaned to the same TR19® standard.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

What your team can do, and what needs us
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
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.
Multi-site and managed buildings
Facilities teams in offices, schools and healthcare sites book us too in Frimley and across Surrey. Larger estates can be phased building by building around the people who use them.
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.
What grease filter exchange looks like in Frimley
The FSA’s food hygiene register shows about 39 cafés, restaurants and staff canteens and about 21 sandwich bars and takeaways within roughly a mile and a half of the centre of Frimley. Clogged filters slow the airflow, and busy kitchens like these clog them fast. Surrey Fire and Rescue Service covers Frimley. 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. It’s Surrey Heath council that sends environmental health officers to food businesses in Frimley. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Before-and-after photos from each clean are a simple way to show the extract is in hand.
Term dates shape school work: for a school like Lakeside Primary School, an extract clean fits neatly into a half-term or summer break. Volunteers running a hall kitchen near St. Peter's Church, or anywhere in Frimley, may not know when the extract was last cleaned, and a grease test settles it.
Frimley is about 1 mile south of Camberley, in Surrey.

What’s near Frimley
In Frimley, that means kitchens and buildings near Tomlinscote School, The White Hart Public House and Frimley Lodge Park and the streets around them. Frimley’s nearest station is Frimley station, about 0.7 miles west of the centre. A little further out are Frimley Park Hospital (0.6 miles north-west) and Surrey Heath Museum (1.9 miles north). For a walk, there’s Danger Hill and Wildmoor Heath.
Leave it or put it right?
Clogged filters choke the extract. Heat and fumes hang in the kitchen while the fan strains. A regular exchange keeps the airflow where it should be. A small fault found now is a quick job; the same fault found later can close the site.
The cost depends on the size of the system, the condition it’s in and access to every part of it. We give you a fixed price before any work starts, so you know where you stand.

Frimley: your questions answered
Who is the fire and rescue service for Frimley?
It’s Surrey Fire and Rescue Service, which covers Frimley. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Can a school canteen extract in Frimley be done out of term time?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 23 schools, colleges and universities with registered kitchens within about a mile and a half of Frimley. Tell us your holiday dates and we’ll book the visit for when the site is empty.
What do you do with what you remove?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. None of it is left on site.
Are you accredited?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’ve been trading since 2009 and we are fully insured.
Will we have to stop cooking for a filter change?
A filter change is quick and can be timed around service. The canopy shouldn’t be used without filters, so we swap them in one go.
Does a filter exchange replace TR19 cleaning?
It is not. The rest of the system still collects grease at the right interval.
What happens to the dirty filters?
They leave with us. That is how an exchange works: clean filters in, dirty ones out and nothing greasy left on site.
How long does grease filter exchange take?
We will confirm the time with your quote. For a typical site, it takes less than an hour in most kitchens.
Common problems we fix in Frimley
What a kitchen cooks affects how fast filters clog. Fryers, grills and woks load filters faster than ovens and steamers so no single schedule suits every kitchen.
Look out for any of the following:
- Grease building up behind the canopy filters
- Grease filters clogged with grease
- Filter washing that keeps being missed
- A canopy that drips grease
For kitchens close to Frimley station, where the day often starts early and ends late, the extract can be cleaned overnight.
What your quote should include
- Whether they’re fully insured
- Whether the whole system is included, or only the parts that are easy to reach
- Whether VAT is included
- Whether a survey comes first
Fixed quotes for grease filter exchange in Frimley
Sites vary more than people expect. What affects the quote:
- The condition of the system
- Site rules, permits and inductions
- Travel, parking and unloading
- How big the system is
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are not sure what’s needed, call 0345 646 2711 or drop us a line and we will give you an honest view and a fixed quote.
Helping us quote
Photos let us diagnose from a distance. Try to include:
- How we’d reach plant on a roof or in a plant room
- Your opening hours and when the area is out of use
- The postcode and the type of business
- Any symptoms, from odd noises to smells or leaks
To help us quote: the address, the type of site and when it’s open, a few pictures and any previous report or certificate. Then call 0345 646 2711 or drop us a line.
What we do, step by step
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 we start, and the area around the work is covered and protected. On site, it takes a few minutes per canopy, longer for a large kitchen with several canopies. We arrive in Frimley once you’ve closed and leave the site ready for the morning.
- First, we check the canopies and the filters in them.
- We note any filters that are bent, damaged or missing.
- We exchange the dirty filters for a clean set.
- We check the filters are seated and the canopy is ready to use.
- Anything that needs attention, such as a greasy plenum, is pointed out.
Getting ready for the visit
- Make sure someone can let us in and lock up afterwards
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Dig out any earlier paperwork for the system
Ask for a quote
For a fixed quote, ring 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. You’ll typically have a quote within one working day.
