About our grease filter exchange in West Twyford
A clean set of filters is a simple, regular dose of prevention. 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 drips falling from the filters onto equipment and filters so greasy the air can barely pass, on restaurants and pubs, school and hospital kitchens and mesh 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. In West Twyford, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
The report is your system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

- How many systems or sites are involved
The cost depends on how big the system is, the condition it’s in and access to every part of it. We give you a fixed price before any work starts, so you know where you stand.

Your questions about grease filter exchange in West Twyford
Who would carry out a food hygiene inspection at a kitchen in West Twyford?
The local authority for West Twyford is Ealing council, and its environmental health team does the inspecting. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Which fire authority looks after West Twyford?
West Twyford is in the area of London Fire Brigade. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Can you come out in an emergency?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
Do you provide a certificate or report?
Yes. It’s your proof that the work was done: a dated report with pictures, listing the work and any areas we couldn’t reach.
Do you survey before quoting?
Yes. For many sites, photos and a few details are enough, and larger or hidden systems get a visit.
What does grease filter exchange cost?
It depends on the number and type of filters and how often they’re changed. We’ll give you a fixed quote once we know your canopies.
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.
Where does the waste go?
We take it away at the end of the visit. While we work, it’s kept contained to keep the area clean.
Grease filter exchange in West Twyford: the local picture
Food Standards Agency data counts about 255 cafés, restaurants and staff canteens and about 194 sandwich bars and takeaways within roughly a mile and a half of the centre of West Twyford. Each canopy among them has filters that load with grease and need swapping or cleaning. West Twyford sits within the area of London Fire Brigade. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. Overnight is the normal time to clean a London kitchen extract, so trading isn’t affected.
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Central Middlesex Hospital is the nearest hospital to West Twyford, about 0.6 miles east. Term dates shape school work: for a school like West Twyford Primary School, an extract clean fits neatly into a half-term or summer break.

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 can quote for the whole system.
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so each one has its own record.
Looking after it afterwards
How long the results last depends on use and care. Here’s what we suggest:
- Mention it if the kitchen gets busier
- Look out for drips from the canopy
- Make sure no filter is left out
- Tell us if a filter is bent or damaged
If the plenum behind the filters looks greasy, we say so. That might mean bringing a TR19® clean forward and we can book that in.
Damaged filters leave gaps in the defence. Replacing them early protects the plenum and ductwork.
What we do, step by step
The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. The work on site takes less than an hour in most kitchens, and the area is cleaned down before we leave. In West Twyford, 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.
- An exchange schedule is agreed to suit your cooking.
- The dirty set is lifted out.
- Clean filters go in and we check they sit snugly.
- The dirty filters leave with us and the next visit is booked.
Before we arrive
- Arrange a key holder or contact on site
- Let us know how we reach the system, including roofs, risers and plant rooms
- Move anything stored near the system
How to get a quote
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.
Related advice
Do you need grease filter exchange in West Twyford?
Long cooking hours in West Twyford or anywhere else mean more grease on the filters. A kitchen that cooks all day loads its filters quickly, so it needs more frequent changes.
Signs it’s time to call us include:
- Filter washing that keeps being missed
- Grease collecting in the filter channels
- Missing filters in the filter bank
- Filters so greasy the air can barely pass
For kitchens close to Stonebridge Park station, where the day often starts early and ends late, the extract can be cleaned overnight.
Before you book anyone
- Whether the figure could change on the day
- If they look at the system before pricing
- What records you will receive afterwards
- When they can work, and whether that is outside your opening hours
What happens if it’s left?
When filters block, extraction suffers. The kitchen gets hotter and smokier, and the fan works harder to pull air through. Keeping filters clean keeps the extract working properly. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
We don’t list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we will explain what it covers.

What the work involves, part by part
School, care home and staff kitchens
A longer exchange interval may suit lighter cooking. We agree the schedule to match.
Mesh filters
Layers of mesh catch grease droplets. They clog quickly in a busy kitchen, so they need changing often.
