Grease filter exchange in Chainhurst, Kent
Grease filter exchange for Chainhurst and the surrounding area: a survey, a fixed price, careful work and proper paperwork. Ask us for a fixed quote.
- Hand-washed filters that still look greasy
- A canopy running with filters missing
- Grease filters clogged with grease
Leave it or put it right?
Filters full of grease are fuel sitting right above the cooking. Flames from the range can be drawn up into the canopy, and from there into the duct. Clean filters mean less fuel in the canopy. It’s worth booking a check, because nobody sees inside a duct day to day.
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. You’ll have a fixed price before any work starts.
Why us?
- Work around your opening hours, with 24/7 emergency cover
- One number for every site across the South East and London
- Accredited under CHAS and SafeContractor, with ISO 9001
- Survey first, then a fixed quote

Grease filter exchange in Chainhurst
Each visit is quick and tidy. The greasy filters come out, clean ones go in and make sure there are no gaps between them. If something looks wrong, we tell you. If you’re dealing with filter washing that keeps being missed and a canopy that drips grease, we can put it right.
Work in a small place like Chainhurst starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
Good records are part of the job. Each visit is written up with pictures, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

What else we do in Chainhurst
When to call us in Chainhurst
The type of cooking matters. Fryers, grills and woks load filters faster than ovens and steamers so no single schedule suits every kitchen.
It’s time to book a visit if you see:
- Grease left in baffles after washing
- Drips falling from the filters onto equipment
- Smoke and heat lingering under the hood
- Filters that leave gaps in the canopy
A TR19® clean in Chainhurst doesn’t stop at the filters: the plenum, ductwork, fan and discharge are cleaned too.
Before booking anyone
- Whether the work can be done while the site is closed
- Whether a survey comes first
- Whether they recommend a next date
- If the quote is a fixed price or an estimate
Aftercare tips
To keep the system working properly between visits:
- Watch for grease drips between visits
- Don’t let the full clean slip because filters are changed
- Keep every filter in place during service
- Make sure we can reach the canopy on exchange day
The next exchange is already in the diary. If the kitchen gets busier, the interval can be shortened to match.
Saturated filters let more grease through. Getting onto a regular exchange now keeps grease out of the plenum and ductwork between full cleans.
Part by part
Busy restaurant and pub kitchens
The more a kitchen cooks, the more grease the filters see. Regular changes help protect the ductwork.
Mesh filters
Mesh filters use layers of metal mesh to trap grease. In a busy kitchen, mesh soon blocks and need frequent attention.
What grease filter exchange looks like in Chainhurst
Chainhurst is covered by Kent Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. We cover Chainhurst, about 32 miles from central London, as part of our work across London and the South East. We work evenings, overnight and at weekends, so the visit fits around the site.
Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Chainhurst is Oakwood Hospital, about 4.6 miles north.
Chainhurst is about 5 miles south-west of Maidstone, in Kent. Sites in Chainhurst get the same service as everywhere we cover: diagnosis first, a fixed price, out-of-hours working where needed and a written report with pictures. Across Kent, we cover 922 places, Chainhurst among them.

If you need grease filter exchange in Chainhurst, phone us on 0345 646 2711, or email photos. Tell us what kind of premises it is and when it’s open, and send pictures or your last report if you can. We usually send a fixed quote within one working day.
In-house cleaning or a specialist?
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Chainhurst: your questions answered
Who is the fire and rescue service for Chainhurst?
Kent Fire and Rescue Service is the fire and rescue service for Chainhurst. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Do you clean school canteen extracts around Chainhurst out of term?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 3 schools and colleges with food registrations within roughly a mile and a half of Chainhurst. Booking early in the term gives the best choice of holiday dates.
Is there a cleaning option for the filters we have?
Yes, filters can be cleaned on a schedule as well as exchanged. We will explain the options when you get in touch.
What types of premises do you cover?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
How much does a filter exchange service cost?
We price it on the number of filters and the visit frequency. Send us details or photos and we will quote, typically within one working day.
What paperwork should we keep on file?
The reports and certificates from each visit, plus your own logs. Insurers, fire officers and EHOs may all ask to see them, so keep them together and easy to find.
Is there a survey before the work?
Yes. Every job is surveyed first, from your photos and details, or with a visit where necessary. Then you get a fixed quote.
Which accreditations do you hold?
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.
How it works
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before we start, and the area around the work is covered and protected. On site, it takes well under an hour for most canopies. If you can send pictures, we can arrive in Chainhurst knowing what to expect.
- First, we check the canopies and the filters in them.
- Any damaged or missing filters are noted.
- Greasy filters are swapped for clean ones.
- The filters are checked for fit before we go.
- We tell you if the plenum or canopy needs a clean.
Before we arrive
- Tell us where we can park and unload
- Tell us about site rules, permits or sign-in
- Mention any locked doors, roof access or ceiling voids
Getting a quote
There’s no standard price list, because no two systems are the same. We look at your system first, from pictures or on a visit, then send a fixed quote. To get going, give us a ring on 0345 646 2711 or send us an email.
