Bocking grease filter exchange
Our technicians work in Bocking on grease filter exchange. Out-of-hours visits, a fixed quote and a written report with pictures on every job.

- Grease collecting in the filter channels
- Grease left in baffles after washing
Multi-site and managed buildings
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We’re happy to deal with either side and send the paperwork to whoever needs it.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
Grease filter exchange for kitchens and businesses in Bocking
A filter service works alongside TR19® cleaning, not instead of it. Clean filters reduce the grease reaching the ducts, but some grease still passes through as vapour. So the canopy, plenum and ducts still need their full TR19 clean. If you’re dealing with hand-washed filters that still look greasy and poor airflow through the filters, we can put it right, from island canopies, mesh filters and school and hospital kitchens onwards.
For a smaller kitchen near Bocking, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. We plan the visit around your hours, with the journey sorted in advance.
Every visit ends with a written report and pictures, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What a clean won’t put right
An honest diagnosis matters more to us than a booking, so here’s what grease filter exchange will not do:
- A heavily greased plenum or canopy, which needs cleaning to TR19
- Extraction problems caused by the fan rather than the filters
- Greasy ducts and risers that a filter change will not reach
If in doubt, phone us on 0345 646 2711 or use the quote form and we’ll say what we think before you book.

In-house cleaning or a specialist?
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That’s our job.
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
How it works
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 first, and floors and nearby surfaces are sheeted. On site, it takes a few minutes per canopy, longer for a large kitchen with several canopies. In a smaller place like Bocking, parking is rarely the issue, but tell us about gates, roof access and opening hours.
- 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.
- Clean filters go straight back in, seated properly with no gaps.
- We flag any damaged filters or anything wrong with the canopy.
Preparing for the visit
- Make sure equipment near the work can be switched off and left to cool
- Let us know about parking and loading
- Mention any sign-in, permit or induction we need

Questions from Bocking
Can you come to Bocking after we close?
Yes. We work evenings, overnight and at weekends. The work in Bocking can fit around your hours. Let us know the hours you’re closed and we will book within them.
Can school kitchens in Bocking be cleaned in the holidays?
Yes, and it’s the easiest time to do it. The FSA’s register shows about 14 schools and colleges with food registrations within roughly a mile and a half of Bocking. You can give us a ring on 0345 646 2711 or use the quote form with the dates the site is empty.
What about areas you cannot get to?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.
Can damaged filters stay in the canopy?
We check every filter at each visit. Any that are bent or damaged are flagged, because gaps let grease into the plenum.
What does grease filter exchange cost?
Every kitchen is different, so we quote once we know your filters and schedule. We give you a fixed quote before the first visit.
What accreditations do you have?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
Do you offer maintenance contracts?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. The report from each visit recommends the next date.
Does the report say when we need you again?
Yes. The recommended date is on the report. BESA’s minimum intervals for kitchen extracts range from 3-monthly for heavy use to 12-monthly for light use, and fire dampers need testing at least once a year.

What affects the quote in Bocking
We do not publish a price list, because no two systems are the same. What we look at:
- Whether we need access equipment or extra panels
- A single visit or a regular plan
- Site rules, permits and inductions
- The size of the system
Working hours, access and the scale of the site can all change the price. We take each of them into account and give you a fixed price before any work starts.
What to send for a quote
We can often survey from photos. The most useful are:
- Your last certificate, test record or report
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Photos showing the whole system and its surroundings
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
To help us quote: where the site is, what it is and its opening hours, photos of the system and the last certificate or report, if there is one. Once you have those, call us on 0345 646 2711 or use the quote form.
Kitchen extracts in Bocking
There are about 65 restaurants, cafés and canteens and about 35 takeaways and sandwich shops in and around Bocking, up to about a mile and a half out, according to the Food Standards Agency’s register. Any of those kitchens with a canopy relies on its filters to catch grease before it reaches the duct. Food hygiene inspections in Bocking are the job of Braintree council’s environmental health team. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after. Essex County Fire and Rescue Service covers Bocking. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
School kitchens, at schools like St Francis Catholic Primary School for example, are typically cleaned in the holidays so no lunches are lost. Church and community hall kitchens, near Church of St Peter or anywhere around Bocking, are easy to forget, but their extracts collect grease like any other. If you run catering at a healthcare site, such as a hospital like St Michael's Hospital about 0.5 miles south-west, the extract may need cleaning more often than a part-time kitchen.

Between visits
Once we have finished, these simple steps help:
- Keep the extract on whenever the range is in use
- Report damaged filters so they can be replaced
- Don’t let the full clean slip because filters are changed
- Wipe the outside of the canopy as part of daily cleaning
Nothing changes for your staff, except one less greasy job. Make sure we can reach the canopy on exchange day and tell us if service times change.
Clean filters plus regular full cleans keep the system in good health. Setting both up on a schedule means neither slips.
What the work involves, part by part
Baffle filters
Baffle filters use overlapping metal blades that force the air to change direction. Grease is thrown out of the airstream and collects on the baffles.
The plenum
Behind the filters sits the plenum, where air gathers before the duct. It collects whatever grease the filters miss.
