Why it’s worth doing now in St John's Wood
Dripping canopies and greasy smells often start with the filters. Left, it ends up on equipment, food areas and staff, which an EHO may well notice. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and the price is agreed before we start.

Grease filter exchange for kitchens and businesses in St John's Wood
Cleaning filters by hand takes staff time and is easy to put off. With a filter exchange, we bring a clean set and take the dirty one away and the canopy is refilled right away. We are often asked to deal with grease left in baffles after washing and filters left unwashed on busy weeks, on mesh filters, school and hospital kitchens and baffle filters.
London kitchens are often tucked into basements or the back of a building, and the duct may run up through several floors before it discharges at the roof. For a kitchen in St John's Wood, that normally means a longer system to clean and more access panels to plan around.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Aftercare tips
Aftercare is simple, and it makes the next visit easier:
- Watch for grease drips between visits
- Make sure no filter is left out
- Report damaged filters so they can be replaced
- Keep the canopy clear for exchange visits
There’s no waiting: the canopy is ready as soon as the clean set is fitted. We take the greasy filters with us for cleaning.
Damaged filters leave gaps in the defence. Replacing them early protects the plenum and ductwork.
Common questions in St John's Wood
Do you work at weekends in St John's Wood?
Yes, we can come after you close and finish before you open. It means the site in St John's Wood keeps running as normal. Let us know the hours you are closed and we’ll book within them.
Who would carry out a food hygiene inspection at a kitchen in St John's Wood?
In St John's Wood, it’s Camden council that carries out food hygiene inspections. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Do you deal with bent or broken filters?
A badly damaged filter should be replaced. We’ll tell you which ones and why when we find them.
What happens if you cannot reach some of it?
The report shows them clearly. In ductwork, new access panels are often the answer, and we can fit those.
Do you work in St John's Wood?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, and that includes St John's Wood.
Do you handle baffle and mesh filters?
Baffle filters and mesh filters. Tell us what you have when you phone us on 0345 646 2711 or email us, or we’ll check on the first visit.
Which sectors do you work in?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
Who has the legal duty for fire safety?
In the words of the Fire Safety Order 2005, it’s the responsible person. That is generally the employer or the person in control of the premises, and in shared buildings more than one person can have duties. Your lease and fire risk assessment should make it clear.
Honest limits
Not every problem is solved by grease filter exchange, and we’ll tell you before any work starts. It does not solve:
- Greasy ducts and risers that a filter change won’t reach
- Smell complaints that need odour control equipment
- A fan that is failing or too weak for the system
If you are not sure, just call 0345 646 2711, or send details by email and we will give you a straight answer before you book.

What affects the quote in St John's Wood
Some jobs are bigger than they look, and some smaller. The main factors:
- Whether it’s a one-off visit or part of a schedule
- Any permits to work or inductions
- Whether we need access equipment or extra panels
- How big the system is
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will explain each part.
What we need to know
When you contact us, it’s useful to have:
- The postcode and the type of business
- Your last certificate, test record or report
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Close-ups of filters, grilles, hatches or access panels
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.
Landlords, agents and facilities managers
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 records stay tidy.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.
Signs you need grease filter exchange in St John's Wood
Missing filters are more common than you’d think. Every gap in the filter bank lets grease straight into the plenum and on into the ductwork.
Look out for these warning signs:
- Drips falling from the filters onto equipment
- Bent or damaged filters that don’t sit properly
- Staff short of time to wash filters
- Blocked baffle filters
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Hospital of St John and St Elizabeth is the nearest hospital to St John's Wood, about less than half a mile south.
Before booking anyone
- Which accreditations they hold, and whether you can check them
- Proof of insurance

What happens on the day
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes a few minutes per canopy, longer for a large kitchen with several canopies. Loading bays, visitor permits and roof access are the first things we ask about for a site in St John's Wood.
- We look at the canopies and the condition of the filters.
- 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.
How to prepare
- Agree a time when the area can be out of use
- Move anything stored near the system
- Tell us where we can park and unload
