Grease Filter Exchange in Elstree
Grease filter exchange across Elstree and nearby, booked around your opening hours and signed off in writing with photos.
- Filter washing that keeps being missed
- Missing filters in the filter bank
- Filters that leave gaps in the canopy
How the visit works
We start by comparing what we find with the survey or your pictures. If anything is different, we talk it through with the person on site before carrying on. From there, it takes less than an hour in most kitchens. Seeing the system in photos first means the trip to Elstree can be planned properly.
- First, we check the canopies and the filters in them.
- Any damaged or missing filters are noted.
- We exchange the dirty filters for a clean set.
- We check the filters are seated and the canopy is ready to use.
- Anything that needs attention, such as a greasy plenum, is pointed out.
How to prepare
- Agree a time when the area can be out of use
- Have your last certificate or report to hand
- Make sure equipment near the work can be switched off and left to cool

About our grease filter exchange in Elstree
Filter exchange sits between full TR19® cleans. Fresh filters help limit what gets into the ductwork though vapour still carries some grease past them. That is why the whole system still needs cleaning to TR19 at the right interval. If you have gaps where filters have been removed and grease filters clogged with grease, we can put it right.
Somewhere as small as Elstree, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease, whatever the size of the place.
For insurers and inspectors, the record counts. That is why every job is written up in a report with photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

In-house cleaning or a specialist?
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.

When it’s something else
In fairness, some problems need a different fix:
- An extract that was undersized from the start
- A heavily greased plenum or canopy, which needs cleaning to TR19
- Extraction problems caused by the fan rather than the filters
If in doubt, phone us on 0345 646 2711, or email photos and we will say what we think.

What grease filter exchange looks like in Elstree
The FSA’s food hygiene register includes about 8 bars, pubs and nightclubs across Elstree and its immediate surroundings (about a mile and a half). Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. The fire and rescue service for Elstree is Hertfordshire Fire and Rescue Service. 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. It’s Hertsmere council that sends environmental health officers to food businesses in Elstree. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Our report lists what was cleaned and when, which is useful to have ready.
A hospital like Royal National Orthopaedic Hospital, about 0.8 miles south, is the kind of site where a kitchen may cook for patients, staff and visitors all day. If you run a church or community hall kitchen, near Church of St Nicholas or elsewhere in Elstree, its extract still collects grease from every lunch and event.

What we are called out for in Elstree
What a kitchen cooks affects how fast filters clog. Fryers, grills and woks load filters faster than ovens and steamers, so the right exchange interval varies.
Common reasons sites call us are:
- Grease dripping from the canopy
- Filters left unwashed on busy weeks
- Grease filters clogged with grease
- Damaged filters letting grease past
For schools such as St Nicholas Elstree Church of England VA Primary School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed.

Common questions in Elstree
Do you clean school canteen extracts around Elstree out of term?
Yes, holiday work suits schools best. The FSA’s register shows about 12 schools and colleges with food registrations within roughly a mile and a half of Elstree. 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 come to Elstree after we close?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Your opening times are the first thing we ask for.
Who is responsible for fire safety on the premises?
The Fire Safety Order 2005 calls them the responsible person: normally the employer or whoever controls the premises. In shared or managed buildings, a landlord, facilities manager or managing agent can share the duty.
Where does the waste go?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We do not leave it behind.
Is filter exchange enough instead of a full extract clean?
No. Clean filters help keep grease down, but the ducts and plenum still need cleaning at the right interval.
Can you look after several sites?
Yes. Send the list of sites and the work at each and you will get one fixed quote.
Do you take the used filters away?
The greasy set leaves with us for cleaning, so your staff don’t have to wash them. A clean set is fitted in their place.
Do you have insurance?
Yes. Duct Doctor is fully insured, and the details are available on request.
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 can quote either party and send the paperwork to whoever needs it.
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
How we price grease filter exchange
Some jobs are bigger than they look, and some smaller. The main factors:
- A single visit or a regular plan
- Where the site is and how we reach it
- Whether several sites go on one quote
- Working hours and out-of-hours timing
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll go through it with you.
Helping us quote
A few details help us quote accurately. With your enquiry, please include:
- The postcode and the type of business
- The paperwork from the last visit, if you have it
- Any symptoms, from odd noises to smells or leaks
- Where the plant sits or the system leaves the building, such as a roof or outside wall
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Why deal with it now?
Grease dripping from the canopy is a sign the filters cannot hold any more. Left, it ends up on equipment, food areas and staff and that is the kind of thing inspectors look for. In a place like Elstree, ductwork and fans are easy to forget until something goes wrong.
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 will talk you through it.
