How we handle grease filter exchange in Enfield
Think of filter exchange as routine care for the extract. Between full cleans, it keeps the airflow healthy, and it saves your staff a greasy job. Full TR19 cleaning still comes at the right interval, with a certificate. We’re often asked to deal with filters so greasy the air can barely pass and grease building up behind the canopy filters, on school and hospital kitchens, wall canopies and baffle filters.
London kitchens are often tucked into basements or the back of a building, with extract ducts that can climb several floors to discharge at roof level. For a kitchen in Enfield, that normally means a longer system to clean and more access panels to plan around.
Good records are part of the job. You get a written report with photos after every visit, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Grease, kitchens and Enfield
Look up Enfield on the FSA’s food hygiene register and you will find about 111 restaurants, cafés and canteens and about 58 takeaways in Enfield and the streets around it, up to about 1.5 miles out. Where they cook under a canopy, the grease filters are the first line of defence and clog quickly. In London, kitchens are normally cleaned overnight, when the kitchen is closed and loading is easier. Enfield sits within the area of London Fire Brigade. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
If you run catering at a healthcare site, such as a hospital like St Michaels Hospital about 0.7 miles north, the extract may need cleaning more often than a part-time kitchen. A kitchen near Enfield Town station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.

Enfield questions
Can the work in Enfield be done at night or at weekends?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Enfield needn’t be disturbed. Let us know the hours you are closed and we will book within them.
Which fire and rescue service is responsible for Enfield?
Fire safety enforcement in Enfield is handled by London Fire Brigade. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Can we skip TR19 cleans if the filters are changed regularly?
No. Filter exchange works between full cleans, not instead of them. TR19® cleaning covers the canopy, plenum, ductwork and fan, with a certificate and photo report.
How much does a filter exchange service cost?
We price it on the number of filters and the visit frequency. Send us details or pictures and we will quote quickly.
What happens to the dirty filters?
The greasy set leaves with us for cleaning and your staff do not have to deal with them. Clean filters go straight in.
Is there a cleaning option for the filters we have?
We can. Some kitchens prefer their own filters cleaned on a schedule, and others prefer a straight swap. We make sure the canopy is ready for service either way.
How often should grease filters be changed?
The right interval depends on the kitchen. If filters clog early, the interval needs shortening, and we can change it.
Can we book visits on a schedule?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.
How it works
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. The visit takes less than an hour in most kitchens. In Enfield, as across London, we usually work overnight or at weekends and hand the site back ready to open.
- We record the number, size and type of your filters.
- We set the interval with you.
- On each visit, we remove the greasy filters.
- A clean set is fitted and checked for gaps.
- We take the greasy set away and confirm the next date.
Preparing for the visit
- Name a contact who can let us in at the agreed time
- Plan for cooking equipment or plant to be off before we arrive
- Have your last certificate or report to hand
How to get a quote
Quoting starts with a diagnosis, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price so you know the cost before any work starts.

In-house cleaning or a specialist?
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That is our job.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Landlords, agents and facilities managers
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
How the job changes from site to site
Busy restaurant and pub kitchens
In a busy kitchen, filter washing is easy to skip. An exchange service takes it off the rota.
School, care home and staff kitchens
Visits can be planned around holidays and quieter periods, keeping the filters ready for the busy weeks.
What affects the quote in Enfield
A fixed price needs a few facts first. We check:
- The condition of the system
- Site requirements such as sign-in and permits
- A single visit or a regular plan
- The number of sites or systems
What you pay reflects the actual work. That is why every job is surveyed first, and why the quote is fixed before work begins.
Helping us quote
To help us quote quickly, send us:
- Where the site is and what kind of site it is
- A few general shots of the system
- The times we could work without disrupting the site
- Where the plant sits or the system leaves the building, such as a roof or outside wall
There’s no standard price list, because no two systems are the same. We look at your system first, from photos or on a visit, then send a fixed quote. To get going, call 0345 646 2711 or use the quote form.
Why act early in Enfield
Grease-loaded filters are a fire risk in their own right. Flames from the range can be drawn up into the canopy and grease in the duct can carry a fire further. Keeping filters clean takes some of that fuel away. London sites work long hours, and the longer a job is left, the bigger it gets.
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You will have a fixed price before work begins.
