Grease filter exchange for kitchens and businesses in Chandler's Cross
The filters in the canopy are the first thing cooking vapour meets. They catch grease before it reaches the plenum and ductwork, but only while they’re reasonably clean. Our grease filter exchange service swaps dirty filters for clean ones on a schedule. The work covers wall canopies, baffle filters and school and hospital kitchens, and common reasons people get in touch are a canopy running with filters missing and poor airflow through the filters.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
For insurers and inspectors, the record counts. So every job comes with a written report and photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What your team can do, and what needs us
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Why deal with it now?
Grease-loaded filters are a fire risk in their own right. Flames from the range can be drawn up into the canopy and grease in the duct can carry a fire further. Clean filters mean less fuel in the canopy. Equipment tucked in a roof space or outbuilding near Chandler's Cross rarely gets looked at unless someone books it.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll go through it with you.

Different parts, different methods
Baffle filters
In a baffle filter, the air zigzags through metal baffles. Grease is thrown out of the airstream and collects on the baffles.
The plenum
Clean filters reduce the grease reaching the plenum, but it’s still cleaned during a full TR19 clean.
When something else is needed
A few issues sit outside what this work can do:
- Greasy ducts and risers that a filter change will not reach
- A canopy that does not capture the vapour properly
- Odours from the discharge that filters won’t stop
If in doubt, call 0345 646 2711 or email us and we’ll say what we think before you book.

Questions from Chandler's Cross
Do you work overnight in Chandler's Cross?
Yes, evening, overnight and weekend work is normal for us. It means the site in Chandler's Cross keeps running as normal. When you give us a ring on 0345 646 2711, or send details by email, mention when the site is quiet.
Is Chandler's Cross within the area you cover?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
Do you have insurance?
Yes, we’re fully insured. CHAS and SafeContractor accreditation sit alongside it, for sites that check contractor safety.
Where do the greasy filters go?
We do. Used filters go with us to be cleaned and the clean set stays in the canopy.
Do you offer maintenance contracts?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.
How regularly do grease filters need exchanging?
That depends on the cooking. Heavy cooking means more frequent changes than kitchens that cook less. We agree the interval with you.
What do you do with what you remove?
We take it away at the end of the visit. During the work, it’s contained so the area stays clean.
Is TR19 cleaning required by law?
No, not in itself. Insurers, fire officers and EHOs look to TR19® as the benchmark, and many insurance policies ask for proof of TR19® cleaning. The law behind it is the Fire Safety Order 2005, which applies in England and Wales.
Between visits
No system stays clean for ever, but care slows the build-up. A few tips:
- Make sure we can reach the canopy on exchange day
- Look out for drips from the canopy
- Always run the extract while cooking
- Tell us if the menu or opening hours change
The next exchange is already in the diary. If cooking increases, we can change filters more often to keep up.
A kitchen that’s getting busier needs its filters changed more often. Adjusting the schedule now prevents a build-up in the ducts.
For landlords and multi-site operators
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.
Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with photos.
What grease filter exchange looks like in Chandler's Cross
There are about 7 restaurants, cafés and canteens across Chandler's Cross and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. Where they cook under a canopy, the grease filters are the first line of defence and clog quickly. Hertfordshire Fire and Rescue Service covers Chandler's Cross. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. Food hygiene inspections in Chandler's Cross are the job of Three Rivers council’s environmental health team. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
Historic houses near Chandler's Cross, such as Chenies Manor House about 3.2 miles west, are a reminder that older buildings with event kitchens can have long, awkward duct routes. A hospital like Watford General Hospital, about 2.9 miles south-east, is the kind of site where a kitchen may cook for patients, staff and visitors all day. Term dates shape school work: for a school like York House School, an extract clean fits neatly into a half-term or summer break.
