Greater London · Grease filter exchange
Grease Filter Exchange in Osterley
Grease filter exchange in Osterley from ventilation hygiene specialists trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- Filter washing that keeps being missed
- Filters that come out of the sink still dirty
- Grease filters clogged with grease
What happens if it’s left?
Grease dripping from the canopy is a sign the filters cannot hold any more. Left, it ends up on equipment, food areas and staff, which an EHO may well notice. In a London building, a problem in a duct, damper or fan rarely stays in one unit.
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.
Why us?
- We diagnose before we treat
- Work around your opening hours, with 24/7 emergency cover
- Ventilation hygiene specialists since 2009
- A written report with photos after every visit

Grease filter exchange for kitchens and businesses in Osterley
We run grease filter exchange for all kinds of kitchens in Osterley, whether there’s one canopy or many. We can come before or after service, so cooking isn’t interrupted. We’re often asked to deal with gaps where filters have been removed and a canopy that drips grease, across baffle filters, restaurants and pubs and island canopies.
Kitchens in Osterley, like many across London, can share a building with flats or offices, with the duct running up through shared risers. A duct fire there can reach parts of the building far from the range, so a regular TR19® clean protects everyone in it.
We have been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

How the visit works
Everything the job needs comes with us, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. The visit takes anything from a few minutes to an hour or so, depending on the number of filters. Managed blocks in London often need contractors booked in ahead, and we are happy to deal with the agent directly for a site in Osterley.
- First, we check the canopies and the filters in them.
- We note any filters that are bent, damaged or missing.
- Greasy filters are swapped for clean ones.
- The filters are checked for fit before we go.
- Anything that needs attention, such as a greasy plenum, is pointed out.
Before we arrive
- Tell us the best time to work, such as after service or at a weekend
- Let us know about parking and loading
- Find the previous report, if there is one
Ask for a quote
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before any work starts.

Your questions about grease filter exchange in Osterley
Which fire authority looks after Osterley?
Osterley is in the area of London Fire Brigade. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Who carries out food hygiene inspections in Osterley?
The local authority for Osterley is Hounslow council, and its environmental health team does the inspecting. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Will I get paperwork for my records?
Yes. You get a written report with pictures after each visit, covering the work, any areas we couldn’t access and the recommended next date. Where the work is a TR19® Grease clean, there’s also a certificate issued through the BESCA Vent Hygiene Elite portal.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. We do not leave it behind.
What does grease filter exchange cost?
We price it on the number of filters and the visit frequency. Send us details or pictures and we will quote quickly.
Can damaged filters stay in the canopy?
Each filter is looked at when we exchange. Any that are bent or damaged are flagged since a poor fit lets grease past.
How much notice should we give?
Earlier is better, particularly for night and weekend visits. We normally quote within one working day, and there’s a 24/7 line for emergencies.
Is filter exchange enough instead of a full extract clean?
No, the two work together. A TR19® clean deals with the whole system, with a certificate and photo report.
How the job changes from site to site
School, care home and staff kitchens
Lighter kitchens can often go longer between changes. We agree the schedule to match.
The plenum
Heavy grease in the plenum often follows clogged or missing filters or that the next TR19 clean is due.

What grease filter exchange cannot fix
We won’t sell you work that does not address the problem, so these are the things it won’t cover:
- Extraction problems caused by the fan rather than the filters
- A canopy too small for the cooking beneath it
- Cooking smells reaching neighbours, which need odour control
If you’re not sure, just give us a ring on 0345 646 2711, or send details by email and we will give you a straight answer.

Grease, kitchens and Osterley
Food Standards Agency records include about 33 pubs, bars and clubs and about 11 hotels and B&Bs within about 1.5 miles of central Osterley. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. London jobs typically start after the last service, with loading and roof access agreed with the building first. London Fire Brigade covers Osterley. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
A hospital like West Middlesex University Hospital, about 1.3 miles south-east, is the kind of site where a kitchen may cook for patients, staff and visitors all day. Bursars and site managers at schools such as Isleworth and Syon School for Boys tend to book extract cleaning for when the kitchen is empty.
Osterley is about 1 mile north of Hounslow, in Greater London.

Our area takes in 764 places across Greater London, from busy centres to quieter spots. London is in our area too, about 11 miles from Osterley.

What your team can do, and what needs us
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
Managing agents and facilities teams in Osterley
Keeping records across a portfolio is half the battle. Each visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
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.
When to call us in Osterley
Filters get bent and damaged with handling. Damaged filters do not sit flush and grease passes round them.
Common reasons sites call us include:
- Grease building up behind the canopy filters
- Smoke and heat lingering under the hood
- Filters that leave gaps in the canopy
- Grease dripping from the canopy
Where a hall near St Mary's Church, or anywhere in Osterley, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
