How we handle grease filter exchange in Green Street
Washing filters in the kitchen sink is messy and easily missed on a busy week. With a filter exchange, we bring a clean set and take the dirty one away, so the canopy is never left without filters. Common call-outs are for a greasy plenum behind the filters and grease filters clogged with grease, on school and hospital kitchens, wall canopies and mesh filters.
For a kitchen in or near Green Street, the visit is planned around opening hours and the journey, and the clean itself is the same full TR19® job as in any town: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

FAQs for Green Street
Do you cover smaller places like Green Street?
Yes. Villages and rural sites across the South East are part of our work, Green Street included. The journey is planned ahead, so a few details about the route help.
Can you come to Green Street after we close?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Just phone us on 0345 646 2711 or drop us a line with your opening times and we’ll plan around them.
Which grease filters does the service cover?
Both baffle filters and mesh filters are covered. At the start, we note what your canopies use so every set we bring fits.
Is TR19 cleaning required by law?
Not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, and many insurance policies ask for proof of TR19® cleaning. The law behind it is the Fire Safety Order 2005 in England and Wales.
Who is the responsible person?
That depends on who controls the premises. The Fire Safety Order 2005 puts the duty on the responsible person, which may be the employer, owner, landlord, facilities manager or managing agent.
What happens to the waste?
It leaves the site with us when we go. During the work, it’s contained so the area stays clean.
What does TR19 mean?
A BESA specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t law, but it’s the benchmark.
Does a filter exchange replace TR19 cleaning?
No. Some grease passes the filters as vapour and settles in the ducts and the whole system still needs its TR19 clean.
Why deal with it now?
When filters block, extraction suffers. The kitchen gets hotter and smokier while the fan strains. A regular exchange keeps the airflow where it should be. It’s worth booking a check, because nobody sees inside a duct day to day.
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before any work starts.

Staff cleaning versus specialist work
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. Leave those to us.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
How it works
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. Most of the time goes on the work itself, which takes a short visit, depending on how many filters the canopies hold. For a village or hamlet like Green Street, tell us about narrow lanes, gates and parking when you book.
- We start by noting how many filters you have and what type they are.
- A change schedule is agreed to match the kitchen’s cooking hours.
- At every visit, the greasy filters are lifted out.
- Clean filters go straight back in, seated properly with no gaps.
- If a filter is damaged or the plenum needs attention, we tell you.
Before we arrive
- Tell us the best time to work, such as after service or at a weekend
- Arrange a key holder or contact on site
- Let us know how we reach the system, including roofs, risers and plant rooms

Here’s what helps us quote: the address, the type of site and when it’s open, photos of the system and any previous report or certificate. Once you have those, call us on 0345 646 2711 or email us.
Advice
Looking after it afterwards
So the system stays in good health:
- Make sure no filter is left out
- Wipe the outside of the canopy as part of daily cleaning
- Tell us if the menu or opening hours change
- Make sure we can reach the canopy on exchange day
The next exchange is already in the diary. If cooking increases, we can change filters more often to match.
If cooking has stepped up, the filter schedule should too. Changing the interval early stops grease building up unseen in the ducts.
Green Street kitchens: local notes
The FSA’s food hygiene register shows about 39 cafés, restaurants and staff canteens and about 16 takeaways within roughly a mile and a half of the centre of Green Street. Each canopy among them has filters that load with grease and need swapping or cleaning. Fire safety in Green Street falls to Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Environmental health officers from Hertsmere council inspect food businesses in Green Street. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A dated certificate in the maintenance file answers the question before it’s asked.
For schools such as Parkside Community Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed. Volunteers running a hall kitchen near St Michael and All Angels Church, or anywhere in Green Street, may not know when the extract was last cleaned, and a grease test settles it.
Green Street is about 1 mile north of Borehamwood, in Hertfordshire. Wherever you are in the WD6 postcode area, we can carry out grease filter exchange at your premises. Our Hertfordshire coverage runs to 381 places, Green Street among them. There’s also a page for London, roughly 14 miles from Green Street.
Grease filter exchange in WD6 follows the same survey, fixed quote and written report as everywhere else we cover.

Local landmarks in Green Street
We work in commercial kitchens and buildings around The White Horse Public House and Hertswood Academy. The nearest railway station is Elstree & Borehamwood station, roughly 1.6 miles south of the centre. Other landmarks nearby include Hilfield Castle (3 miles south-west) and Shenley Hospital (1.6 miles north-west). Not far away are Darland's Lake and Arkley Lane and Pastures.
Landlords, agents and facilities managers
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so records stay tidy.
Common problems we fix in Green Street
However long the kitchen cooks each day, the filters see every minute of it. A kitchen that cooks all day loads its filters quickly, so it needs more frequent changes.
The symptoms we’re asked about most include:
- Hand-washed filters that still look greasy
- A canopy that drips grease
- Missing filters in the filter bank
- Filters so greasy the air can barely pass
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Green Street is Shenley Hospital, about 1.6 miles north-west.

What a clean won’t put right
Grease filter exchange can’t fix everything, and we will tell you before any work starts. It doesn’t solve:
- Extraction problems caused by the fan rather than the filters
- Odours from the discharge that filters will not stop
- Grease behind the filters that a swap cannot remove
If in doubt, give us a ring on 0345 646 2711, or send details by email and we will say what we think before you book.
