Grease filter exchange in Holborn, done properly
In Holborn, our filter exchange runs on a schedule set by how much the kitchen cooks. The heavier the cooking, the more often filters need changing while a lighter kitchen can go longer. The interval is agreed before the first visit. If you have blocked baffle filters and grease dripping from the canopy, we can help.
London kitchens tend to trade late and open early, so work in Holborn is normally booked for the night or the early hours. Parking, loading and access to the roof are agreed with the building before the night of the clean.
Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Holborn: your questions answered
Which environmental health team covers Holborn?
The local authority for Holborn is Camden council, and its environmental health team does the inspecting. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Can you come to Holborn after we close?
Yes, evening, overnight and weekend work is normal for us. That way a site in Holborn doesn’t have to lose a day’s trading. When you ring 0345 646 2711, or email photos, mention when the site is quiet.
Are you fully insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
What happens if you can’t reach some of it?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
Do you work with multi-site operators?
Yes. One number covers all your sites across London and the South East, and visits can be set on a regular cycle.
Which records should we keep?
Each report and certificate we give you, kept together in your maintenance log with your in-house cleaning records. BESA says certificates should show the date, location and technician.
Will you tell us when the next visit is due?
Yes. The interval depends on how much the system is used and what we find and the report sets out why.
Grease, kitchens and Holborn
Food Standards Agency data counts about 4,009 cafés, restaurants and staff canteens and about 872 takeaways in and around Holborn, up to about a mile and a half out. Where they cook under a canopy, the grease filters are the first line of defence and clog quickly. In Holborn, food businesses are inspected by environmental health officers from Camden council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after pictures from each clean are a simple way to show the extract is in hand. London Fire Brigade covers Holborn. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Holborn is Royal London Hospital for Integrated Medicine, about less than half a mile west. If you run a church or community hall kitchen, near St Alban's Church or elsewhere in Holborn, its extract still collects grease from every lunch and event. School kitchens, at schools like St Alban's Church of England Primary School for example, are usually cleaned in the holidays so no lunches are lost.
Holborn is about 2 miles north-west of London, in Greater London. From the centre of Holborn to the outskirts, grease filter exchange is available to all kinds of commercial premises, from small sites to large estates. We cover 764 places across Greater London, from busy centres to quieter spots.
We cover every part of WC1X, WC1N and EC1R for grease filter exchange and the roads nearby. That includes premises on Shoe Lane, Drury Lane and New Square and the roads around them. You’ll find Holborn on the A4 and A40, so it’s easy for us to get to for grease filter exchange. If your site is just outside Holborn, we cover Farringdon (1 mile east), St Pancras (1 mile north-west), Clare Market (1 mile south), Smithfield (1 mile east) and Temple Bar (1 mile south). We also work in nearby towns such as Kensington (4 miles west), Walthamstow (6 miles north-east), Hampstead (4 miles north-west), Ruislip (13 miles west), Brompton (3 miles south-west) and Stockwell (4 miles south).
Around Holborn
Typical jobs here are in premises near The Yorkshire Grey pub, British Library of Political and Economic Science and City Academy. Also close by are Elizabeth Garrett Anderson School (0.9 miles north) and Lincoln's Inn Fields (within half a mile south-west). There’s a railway station in Holborn itself: Farringdon station. Nearby you’ll also find Montfichet's Tower (0.7 miles south-east) and Brunswick Centre (0.5 miles north-west). Green spaces nearby include Barnsbury Wood and Ludgate Hill.
For landlords and multi-site operators
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
We also work for facilities teams across offices, schools and healthcare in Holborn and across Greater London. Work can be phased by floor, building or site around the people who use them.
What staff can safely do
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
What happens on the day
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. On site, the work takes a short visit, depending on how many filters the canopies hold. Expect the work in Holborn to happen after your last customer leaves, not during trading.
- First, we check the canopies and the filters in them.
- We note any filters that are bent, damaged or missing.
- We exchange the dirty filters for a clean set.
- We check the filters are seated and the canopy is ready to use.
- We tell you if the plenum or canopy needs a clean.
How to prepare
- Let us know about permits to work or site inductions
- Have your last certificate or report to hand
- Clear the space around the work

Fixed quotes for grease filter exchange in Holborn
The diagnosis comes before the price. We look at:
- The size of the system
- What state the system is in
- Whether we need access equipment or extra panels
- The times the site is available
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote, and the price is fixed before we start.
Helping us quote
There’s no need for technical detail. It helps if you can send:
- Your opening hours and when the area is out of use
- The postcode and the type of business
- Photos showing the whole system and its surroundings
- Any access panels or hatches you can see
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. Then we send a fixed price, before we start.
Aftercare tips
Good habits slow the build-up between visits. Our tips:
- Don’t refit a filter that is bent
- Keep the extract on whenever the range is in use
- Keep filter exchange and TR19 cleaning on the same plan
- Watch for grease drips between visits
The next exchange is already in the diary. If cooking increases, we can change filters more often to keep up.
Dripping filters are a clear sign they’re full. A clean set right away cuts the grease in the canopy and the plenum may need a clean as well.
Why it’s worth doing now in Holborn
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. Keeping filters clean takes some of that fuel away. Leaving it on a busy London site only adds to the work.
You will not find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll explain what it covers.
