Grease filter exchange in Coldharbour
In Coldharbour, our filter exchange runs on a schedule set by how much the kitchen cooks. The heavier the cooking, the more often filters need changing while a lighter kitchen can go longer. We agree the interval with you at the start. If you’re dealing with filters left unwashed on busy weeks and grease left in baffles after washing, we can put it right.
Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, with extract ducts that can climb several floors to discharge at roof level. For a kitchen in Coldharbour, that normally means a longer system to clean and more access panels to plan around.
A written report with photos follows each visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Why act early in Coldharbour
Grease dripping from the canopy is a sign the filters can’t hold any more. Drips land on surfaces and equipment below, which an EHO may well notice. A building in Coldharbour may have flats or offices above and alongside, and a fault in the system can affect them too.
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered and we’ll price it together.

- We count and measure the filters in every canopy.
- A change schedule is agreed to match the kitchen’s cooking hours.
- 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.

Advice
What affects the cost of grease filter exchange
You will get a fixed price before work begins. It takes into account:
- What state the system is in
- Access, including roofs, risers and ceiling voids
- One-off work versus a regular cycle
- Whether several sites go on one quote
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote and give you a fixed price before work begins.
Helping us quote
Photos and a few facts are often enough to price the work. Useful things to send:
- The roof, plant room or outside wall the system runs to
- The times we could work without disrupting the site
- The postcode and the type of business
- A few general shots of the system
Quotes are quick. Call or email with a few details and you will typically have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
Looking after it afterwards
Good habits slow the build-up between visits. Our tips:
- Wipe the outside of the canopy as part of daily cleaning
- Look out for drips from the canopy
- Don’t let the full clean slip because filters are changed
- Mention it if the kitchen gets busier
Fresh filters improve airflow at the canopy from the moment they’re fitted. Keep the extract running while you cook so they catch grease as intended.
If cooking has stepped up, the filter schedule should too. Changing the interval early stops grease building up unseen in the ducts.

Grease, kitchens and Coldharbour
Look up Coldharbour on the FSA’s food hygiene register and you’ll find about 108 restaurants, cafés and works canteens and about 39 takeaways across Coldharbour and its immediate surroundings (about a mile and a half). Clogged filters slow the airflow, and busy kitchens like these clog them fast. London jobs typically start after the last service, with loading and roof access agreed with the building first. London Fire Brigade covers Coldharbour. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
Commuter trade near Mottingham station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands. For schools such as Mottingham Primary School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed.

The right interval depends on the kitchen. If filters are dripping or clogging before the next change, it’s too long, and we can change it.
How much does a filter exchange service cost?
Filters, canopies and how often you need visits all affect the price. Tell us what you have and we’ll come back with a fixed quote quickly.
What happens to the dirty filters?
We take them away to be cleaned and your staff don’t have to deal with them. Clean filters go straight in.
Do you look at the system first?
Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need, and the quote is based on that.

- Bent or damaged filters that don’t sit properly
- Grease filters clogged with grease
