How we handle grease filter exchange in Hampstead Garden Suburb
A filter that does not sit right lets grease straight past. Bent, damaged or missing filters leave gaps and every filter is checked when we swap them. Damaged filters are flagged so they can be replaced. Typical jobs include missing filters in the filter bank and filters left unwashed on busy weeks, across baffle filters, mesh filters and restaurants and pubs.
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 Hampstead Garden Suburb, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Staff cleaning versus specialist work
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Why act early in Hampstead Garden Suburb
Clogged filters choke the extract. The kitchen gets hotter and smokier while the fan strains. Keeping filters clean keeps the extract working properly. For a site in Hampstead Garden Suburb, fitting the work in overnight now is far easier than closing at short notice later.
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.

Keeping the system healthy
Good habits slow the build-up between visits. A few tips:
- Tell us if the menu or opening hours change
- Never leave gaps in the filter bank
- Report a dripping canopy early
- Wipe the outside of the canopy as part of daily cleaning
We tell you if we spot anything in the canopy that needs attention. That might mean bringing a TR19® clean forward and we can book that in.
Dripping filters are a clear sign they’re full. A clean set right away cuts the grease in the canopy, and it’s worth checking the plenum too.
How it works
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and floors and nearby surfaces are sheeted. On site, it takes less than an hour in most kitchens. For a job in Hampstead Garden Suburb, tell us about loading bays, permits, lifts and roof access when you book.
- We count and measure the filters in every canopy.
- Together we set how often the filters should be changed.
- Each visit starts with the used filters being removed.
- Clean, dry filters are fitted in their place, with no gaps left between them.
- Anything we notice, such as bent filters or a dirty plenum, is pointed out.
How to prepare
- Let us know how we reach the system, including roofs, risers and plant rooms
- Make sure equipment near the work can be switched off and left to cool
- Arrange a key holder or contact on site
Ask for a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

When it’s something else
To be straight with you, some problems need a different fix:
