Grease filter exchange for kitchens and businesses in Langley
Good filters only work when they fit properly. Bent, damaged or missing filters leave gaps, so we check every one at each visit. Damaged filters are flagged so they can be replaced. The work covers school and hospital kitchens, wall canopies and mesh filters, and common reasons people get in touch are damaged filters letting grease past and grease collecting in the filter channels.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. We agree access and timings in advance.
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 are fully insured.

What happens if it’s left?
Clogged filters choke the extract. Heat and fumes hang in the kitchen, and the fan works harder to pull air through. A regular exchange keeps the airflow where it should be. Rural sites can’t always move to another kitchen or room when something fails.
What you pay reflects the actual work. That’s why every job is surveyed first, and the price is agreed before any work starts.

Kitchen extracts in Langley
Food Standards Agency records list about 13 restaurants, cafés and works canteens within roughly a mile and a half of the centre of Langley. Any of those kitchens with a canopy relies on its filters to catch grease before it reaches the duct. Langley is covered by Kent Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. In Langley, food businesses are inspected by environmental health officers from Maidstone council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Our report lists what was cleaned and when, which is useful to have ready.
If you run a church or community hall kitchen, near Church of St Mary or elsewhere in Langley, its extract still collects grease from every lunch and event. If you run catering at a healthcare site, such as a hospital like KIMS hospital about 3.6 miles north, the extract may need cleaning more often than a part-time kitchen. Stoneacre, about 1.1 miles north, is one of the historic houses near Langley; if you run event catering at a venue like that, cleans can be booked between functions.

Common questions in Langley
Can school kitchens in Langley be cleaned in the holidays?
Yes, holiday work suits schools best. Food Standards Agency records list about 8 schools, colleges and universities with registered kitchens within about a mile and a half of Langley. Send us your term dates when you call us on 0345 646 2711, or email photos, and we’ll fit the work in.
Can you work in Langley outside opening hours?
Yes, out-of-hours work is a big part of what we do. It means the site in Langley keeps running as normal. Just ring 0345 646 2711 or drop us a line with your opening times and we will plan around them.
Do you cover Langley?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, and that includes Langley.
What should go in our maintenance log?
Anything that proves the system is maintained: our reports and photos, any certificates and your in-house logs. One maintenance log per site keeps it simple.
Which sectors do you work in?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
How long will you be on site?
Your quote will say how long we expect to be there. In most cases, the work takes a few minutes per canopy, longer for a large kitchen with several canopies.
What’s TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
Do you clean filters as well as exchanging them?
Yes, filters can be cleaned on a schedule as well as exchanged. We will explain the options when we quote.
Keeping the system healthy
Aftercare is simple, and it helps at the next visit:
- Don’t refit a filter that is bent
- Tell us if the menu or opening hours change
- Wipe the outside of the canopy as part of daily cleaning
- Keep the canopy clear for exchange visits
Between visits, check that every filter is still in place. Gaps let grease into the plenum so tell us if you need a replacement.
Saturated filters let more grease through. A regular cycle keeps the rest of the system cleaner between full cleans.
What a clean won’t put right
Not every problem is solved by grease filter exchange, and we’d rather say so up front. It will not put right:
- Greasy ducts and risers that a filter change will not reach
- A noisy or failed extract fan
- A heavily greased plenum or canopy, which needs cleaning to TR19
If in doubt, ring 0345 646 2711 or drop us a line and we will say what we think.

How the job changes from site to site
Canopy filter housings
Grease collects in the channels and drip trays below the filters. We point it out if it needs cleaning.
School, care home and staff kitchens
For kitchens closed in the holidays, visits can be timed around term or rota, keeping the filters ready for the busy weeks.
Managing agents and facilities teams in Langley
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
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 to a regular schedule.
Staff cleaning versus specialist work
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
When your team notices a problem 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’ll take a look and send you a fixed quote.
