Grease filter exchange in Bentley Heath
Good filters only work when they fit properly. Bent, damaged or missing filters leave gaps, so we check every one at each visit. We point out any that need replacing. If you have grease collecting in the filter channels and a canopy that drips grease, we can help, from baffle filters, mesh filters and school and hospital kitchens onwards.
In a London area like Bentley Heath, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. A duct fire there can reach parts of the building far from the range, which is why keeping it clean to TR19® matters.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

Keeping the system healthy
To keep the system working properly between visits:
- Keep every filter in place during service
- Always run the extract while cooking
- Report a dripping canopy early
- Report damaged filters so they can be replaced
Keep an eye out for filters that have been taken out. Gaps let grease into the plenum, so let us know if one goes missing or gets damaged.
Clean filters plus regular full cleans keep the system in good health. Setting both up on a schedule means neither slips.
Landlords, agents and facilities managers
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so each one has its own record.
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we’ll send a fixed quote.
What your team can do, and what needs us
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
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, and that is where we come in.
Bentley Heath kitchens: local notes
The FSA’s food hygiene register includes about 9 pubs and bars within 1.5 miles or so of the middle of Bentley Heath. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Fire safety in Bentley Heath falls to London Fire Brigade. 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. In Bentley Heath, food businesses are inspected by environmental health officers from Hertsmere council. Extraction counts as kitchen equipment, so its condition can come up on the day. A dated certificate in the maintenance file answers the question before it’s asked.
A hall kitchen that only cooks for events, whether near Church of King Charles and the Martyr or elsewhere in Bentley Heath, still needs its extract cleaned, just less often. Term dates shape school work: for a school like Pope Paul Catholic Primary School, an extract clean fits neatly into a half-term or summer break. Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Bentley Heath is Barnet General Hospital, about 2.4 miles south.

How we price grease filter exchange
Sites vary more than people expect. The main factors:
- The times the site is available
- A single visit or a regular plan
- What state the system is in
- How many systems or sites are involved
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. You’ll have a fixed price before any work starts.

To speed up the quote, please include:
- 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
- Your last certificate, test record or report
- Close-ups of filters, grilles, hatches or access panels
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 email us.
How the job changes from site to site
Mesh filters
Mesh traps grease between its layers, so a quick rinse rarely gets it clean.
Canopy filter housings
The trough or channel under the filters fills with grease. We point it out if it needs cleaning.
FAQs for Bentley Heath
How do you handle parking and loading in Bentley Heath?
London parking can be tight, so details of loading bays and permits help. Where restrictions apply in the day, an evening or overnight visit normally gets round them.
Can school kitchens in Bentley Heath be cleaned in the holidays?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 9 schools, colleges and universities with registered kitchens within about a mile and a half of Bentley Heath. Just ring 0345 646 2711, or send details by email with your term dates and we’ll plan around them.
Does the report say when we need you again?
Yes. We put a recommended next date 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.
Does a filter exchange disrupt service?
A change takes anything from a few minutes to an hour or so, depending on the number of filters, so disruption is small. We plan visits outside your busiest times wherever possible.
How long does grease filter exchange take?
The work itself takes a short visit, depending on how many filters the canopies hold. Larger systems naturally take longer, and we will tell you what to expect.
How much notice do you need?
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.
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 are fully insured.
How much does a filter exchange service cost?
Every kitchen is different, so we need to know the filters and interval first. You get a fixed price before the service starts.
What grease filter exchange cannot fix
A few issues sit outside what this work can do:
- Grease already built up in the ductwork, which needs a full TR19 clean
- Cooking smells reaching neighbours, which need odour control
- An extract that was undersized from the start
If you are not sure, just call 0345 646 2711 or email us and we’ll give you a straight answer.

What we do, step by step
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes well under an hour for most canopies. For a job in Bentley Heath, tell us about loading bays, permits, lifts and roof access when you book.
- First, we check the canopies and the filters in them.
- We note any filters that are bent, damaged or missing.
- Greasy filters are swapped for clean ones.
- We check the filters are seated and the canopy is ready to use.
- We tell you if the plenum or canopy needs a clean.
Getting ready for the visit
- Let us know about permits to work or site inductions
