When to call us in South Street
Wherever you are, South Street included, filter washing is the job that gets skipped when the kitchen is busy. A missed wash or two is all it takes for a filter bank to clog.
Look out for these warning signs:
- Missing filters in the filter bank
- Damaged filters letting grease past
- Grease collecting in the filter channels
- Hand-washed filters that still look greasy
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Tandridge Priory is the nearest hospital to South Street, about 3.2 miles south.

How we handle grease filter exchange in South Street
A filter service works alongside TR19® cleaning, not instead of it. Fresh filters help limit what gets into the ductwork, but some grease still passes through as vapour. That’s why the whole system still needs cleaning to TR19 at the right interval. The work covers island canopies, school and hospital kitchens and baffle filters, and the jobs we see most are filters left unwashed on busy weeks and filters so greasy the air can barely pass.
In a London area like South Street, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. Grease in a duct like that is a fire risk to the whole building, not just the kitchen, which is why keeping it clean to TR19® matters.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Landlords, agents and facilities managers
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so records stay tidy.
Grease filter exchange around South Street
Food Standards Agency records list about 11 restaurants, cafés and canteens and about 10 sandwich bars and takeaways across South Street and its immediate surroundings (about a mile and a half). Where they cook under a canopy, the grease filters are the first line of defence and clog quickly. In London, kitchens are typically cleaned overnight, when the kitchen is closed and loading is easier. It’s Bromley council that sends environmental health officers to food businesses in South Street. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after.
If you look after a school kitchen, at a school such as Charles Darwin School or anywhere near South Street, the holidays are the usual time for a TR19® clean. If your kitchen is in a listed or historic building, like the houses around South Street (Titsey Place is about 2.1 miles south-west), fitting access panels needs care.

What staff can safely do
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Looking after it afterwards
How long the results last depends on use and care. We suggest:
- Book full TR19 cleans alongside filter changes
- Wipe the outside of the canopy as part of daily cleaning
- Clear anything stored on or near the canopy
- Watch for grease drips between visits
Once the clean filters are in, the kitchen can cook right away. We take the greasy filters with us to be cleaned.
Saturated filters let more grease through. A regular cycle keeps the rest of the system cleaner between full cleans.
What happens on the day
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. The visit itself takes a few minutes per canopy, longer for a large kitchen with several canopies. Expect the work in South Street to happen after your last customer leaves, not during trading.
- 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.
- We tell you if the plenum or canopy needs a clean.
Preparing for the visit
- Make sure someone can let us in and lock up afterwards
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Find the previous report, if there is one
Getting a quote
We do not publish a price list, because every site is different. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To get going, give us a ring on 0345 646 2711 or send us an email.

How we price grease filter exchange
Before we fix a price, we need to know a few things. We check:
- Working hours and out-of-hours timing
- Any permits to work or inductions
- Whether several sites go on one quote
- What state the system is in
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you are not sure what’s needed, call 0345 646 2711 or drop us a line for straight advice and a fixed quote.
Helping us quote
To help us quote quickly, send us:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Any access panels or hatches you can see
- Wide photos of the system and the area around it
- When the site is open and when it’s quiet
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Your questions about grease filter exchange in South Street
Do you work at weekends in South Street?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Your opening times are the first thing we ask for.
Which fire service covers South Street?
London Fire Brigade is the fire and rescue service for South Street. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Do you have a 24/7 line?
Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we will talk you through the next steps.
What paperwork should we keep on file?
Anything that proves the system is maintained: reports, certificates, pictures and your own cleaning or check logs. One maintenance log per site keeps it simple.
Do you look at the system first?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
What’s the right interval for changing filters?
It depends on how much and what the kitchen cooks. Kitchens that fry and grill all day need changes more often than lighter ones. We set a schedule that suits your kitchen.
What types of premises do you cover?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
Do we need to close while you work?
Not typically. We need the work area to ourselves while we’re on site, so the visit goes in a quiet slot.

Why deal with it now?
A filter exchange is a few minutes; a choked extract affects a whole service. Few maintenance jobs are as easy, and one of the easiest to let slip. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
What you pay depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before any work starts, so you know where you stand.
