Grease filter exchange around Trench Green
We cover Trench Green, about 40 miles from central London, as part of our work across London and the South East. Evening, overnight and weekend visits are all possible. Trench Green sits within the area of Royal Berkshire 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.
If you run catering at a historic house or estate in the area (Mapledurham House is about 1.1 miles south-west), event kitchens in older buildings often have awkward duct runs that need planning. Where a hall near Church of St Margaret and Bardolf Aisle, or anywhere in Trench Green, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
Trench Green is about 2 miles north-west of Caversham, in Reading. From the centre of Trench Green to the outskirts, grease filter exchange is available to all kinds of commercial premises, from a single unit to a large public building.

Grease filter exchange in Trench Green, done properly
A filter that doesn’t sit right lets grease straight past. Bent, damaged or missing filters leave gaps and every filter is checked when we swap them. We point out any that need replacing. Common call-outs are for a canopy running with filters missing and filters so greasy the air can barely pass, across wall canopies, restaurants and pubs and island canopies.
In a village or hamlet like Trench Green, the kitchens that need extract cleaning are typically a pub, a school, a care home or a hall kitchen, wherever there is one. Each still has a canopy and duct that collect grease.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Do you need grease filter exchange in Trench Green?
The type of cooking matters. Fryers, grills and woks load filters faster than ovens and steamers, so the right exchange interval varies.
Signs it’s time to call us include:
- Staff short of time to wash filters
- Blocked baffle filters
- Filters that come out of the sink still dirty
- A canopy that drips grease
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Trench Green is Battle Hospital, about 2.6 miles south.
Before booking anyone

Trench Green: your questions answered
Which council inspects kitchens in Trench Green?
That is South Oxfordshire council, whose environmental health officers carry out food hygiene inspections in Trench Green. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Can you come to Trench Green after we close?
Yes. We work evenings, overnight and at weekends. That way a site in Trench Green doesn’t have to lose a day’s trading. Let us know the hours you’re closed and we’ll book within them.
Are you accredited?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.
What happens to the waste?
We take it away at the end of the visit. During the work, it’s contained so the area stays clean.
Who is responsible for fire safety on the premises?
It depends on the building. Under the Fire Safety Order 2005, it’s the responsible person, which can be the employer, the owner, a landlord, an FM or a managing agent.
What about areas you can’t get to?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, along with a quote to put access in.
How long does the visit take?
We will confirm the time with your quote. For a typical site, it takes anything from a few minutes to an hour or so, depending on the number of filters.
Do I get a report after the visit?
Yes. Each visit ends with a written report and photos, showing what was done, anything we couldn’t reach and when the next visit is due. Where the work is a TR19® Grease clean, there’s also a certificate issued through the BESCA Vent Hygiene Elite portal.
How the job changes from site to site
Baffle filters
When baffles fill with grease, less air gets through. A clean exchange set brings the airflow back.
Canopy filter housings
Grease collects in the channels and drip trays below the filters. If it needs attention, we will tell you.
What grease filter exchange can’t fix
We’ll always give you a straight diagnosis, so here’s what grease filter exchange won’t do:
- A canopy too small for the cooking beneath it
- Grease behind the filters that a swap cannot remove
- Cooking smells reaching neighbours, which need odour control
If in doubt, phone us on 0345 646 2711, or email photos and we’ll say what we think.
What the work covers
- Restaurants and pubs
- Baffle filters
- Island canopies
- Mesh filters
- Wall canopies
- School and hospital kitchens
Looking after it afterwards
Aftercare is simple, and it makes the next visit easier:
- Keep every filter in place during service
- Keep the canopy clear for exchange visits
- Always run the extract while cooking
- Report damaged filters so they can be replaced
Fresh filters improve airflow at the canopy straight away. Always run the extract during cooking so the filters do their job.
A kitchen that is getting busier needs its filters changed more often. Adjusting the schedule now prevents a build-up behind the canopy.
How the visit works
Everything the job needs comes with us, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes anything from a few minutes to an hour or so, depending on the number of filters. Rural roads and tight entrances are worth telling us about before a visit to Trench Green.
- We count and measure the filters in every canopy.
- We agree a schedule that suits how much the kitchen cooks.
- On each visit, the dirty filters come out of the canopy.
- We fit clean filters and check they sit snugly in the housing.
- Anything we notice, such as bent filters or a dirty plenum, is pointed out.
Preparing for the visit
- Clear the space around the work
- Tell us about site rules, permits or sign-in
- Tell us where we can park and unload
Ask for a quote
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. Then we send a fixed price, before any work starts.
Related advice
Staff cleaning versus specialist work
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.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
