Grease filter exchange in Castle Green
A filter that does not sit right lets grease straight past. Bent, damaged or missing filters leave gaps, so we check every one at each visit. Damaged filters are flagged so they can be replaced. The work covers school and hospital kitchens, mesh filters and wall canopies, and people most often call us about damaged filters letting grease past and a canopy running with filters missing.
Kitchens in Castle Green, like many across London, can share a building with flats or offices, with the duct running up through shared risers. 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.
Good records are part of the job. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

Aftercare tips
Here’s the after-treatment advice, in brief:
- Don’t let the full clean slip because filters are changed
- Never leave gaps in the filter bank
- Keep the extract on whenever the range is in use
- Report a dripping canopy early
Once the clean filters are in, the kitchen can cook right away. The dirty set leaves with us for cleaning.
Damaged filters leave gaps in the defence. Sorting them now keeps grease where it can be caught.
Part by part
Baffle filters
When baffles fill with grease, less air gets through. A clean exchange set brings the airflow back.
Busy restaurant and pub kitchens
Kitchens that fry and grill all day load their filters fast. Their exchange schedule is typically the tightest.

How we price grease filter exchange
Sites vary more than people expect. The main factors:
- Access, including roofs, risers and ceiling voids
- The condition we find in the survey
- The scale of the work
- Parking and loading at the site
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.
What to send for a quote
You don’t need the technical terms. It helps if you can send:
- Any access panels or hatches you can see
- When the site is open and when it’s quiet
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The paperwork from the last visit, if you have it
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.
What your team can do, and what needs us
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
FAQs for Castle Green
Can a school canteen extract in Castle Green be done out of term time?
Yes, and it’s the easiest time to do it. The FSA’s register shows about 42 schools and colleges with food registrations within roughly a mile and a half of Castle Green. Send us your term dates when you give us a ring on 0345 646 2711 or send us an email, and we’ll fit the work in.
Can parking be tricky for a job in Castle Green?
Tell us where a van can stop near your site in Castle Green, and about any building rules on loading. Night visits tend to make loading easier on London streets.
Is there a survey before the work?
Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need and the fixed quote is built on it.
Do you deal with bent or broken filters?
A bent filter leaves a gap for grease. We point them out on the visit and explain what’s needed.
Can you give a price for filter changes?
Filters, canopies and how often you need visits all affect the price. Send us details or pictures and we will quote quickly.
Will I get paperwork for my records?
Yes, on every job. It’s a dated, written report with pictures, and TR19® Grease cleans come with a certificate through the BESCA VHE portal. File it with your fire safety records.
How regularly do grease filters need exchanging?
It varies with the type and amount of cooking. If filters clog early, the interval needs shortening, and we can change it.
Can you set up regular visits?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
Castle Green kitchens: local notes
Food Standards Agency data counts about 84 restaurants, cafés and canteens and about 92 takeaways across Castle Green 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. Food hygiene inspections in Castle Green are the job of Barking and Dagenham council’s environmental health team. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Our report lists what was cleaned and when, which is useful to have ready. Most London extract cleaning happens at night, after the last service.
Term dates shape school work: for a school like Jo Richardson Community School, an extract clean fits neatly into a half-term or summer break. If you run catering at a historic house or estate in the area (Eastbury Manor House is about 1 mile west), event kitchens in older buildings often have awkward duct runs that need planning. Volunteers running a hall kitchen near St John the Divine, or anywhere in Castle Green, may not know when the extract was last cleaned, and a grease test settles it.

Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We are happy to deal with either side, and the report can go to both.
How it works
A visit follows the same order every time: sheeting and protection first, make the system safe, do the work, clear away and hand over the paperwork. On site, the work takes a short visit, depending on how many filters the canopies hold. A name and number for whoever controls access to the building in Castle Green saves time on the night.
- The filters in each canopy are measured and counted.
- An exchange schedule is agreed to suit your cooking.

Advice
Leave it or put it right?
Washing filters in-house is an option for kitchens in Castle Green, and it works when it’s done well and never skipped. When it does not happen reliably, an exchange makes it automatic. London sites work long hours, and the longer a job is left, the bigger it gets.
The price reflects the work, not guesswork. That is why we survey first, from pictures or on site, and the price is agreed before work begins.
