Grease filter exchange in Woodcote Green
Grease filters are the first line of defence in a kitchen extract. They catch grease before it reaches the plenum and ductwork and they do it best when they’re clean. With grease filter exchange, clean filters replace greasy ones at regular intervals. The work covers mesh filters, island canopies and school and hospital kitchens, and common reasons people get in touch are a greasy plenum behind the filters and a canopy that drips grease.
London kitchens tend to trade late and open early, so extract cleaning in Woodcote Green is typically done overnight, after the last service. Parking, loading and access to the roof are agreed with the building before the night of the clean.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

What we do, step by step
Your staff don’t need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. In a London area like Woodcote Green, parking, loading and building access are planned before the day of the work.
- The filters in each canopy are measured and counted.
- We set the interval with you.
- On each visit, we remove the greasy filters.
- A clean set is fitted and checked for gaps.
- The dirty filters leave with us and the next visit is booked.
Getting ready for the visit
- Let us know about parking and loading
- Tell us the best time to work, such as after service or at a weekend
- Let us know about permits to work or site inductions
Getting a quote
To get a fixed quote, give us a ring on 0345 646 2711 or drop us a line and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We normally come back within one working day.

What staff can safely do
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Honest limits
We’ll always give you a straight diagnosis, so here’s what grease filter exchange will not do:
- Smell complaints that need odour control equipment
- An extract that was undersized from the start
- Grease already built up in the ductwork, which needs a full TR19 clean
Not sure which it is? You can call us on 0345 646 2711 or email us and we’ll tell you honestly.

Woodcote Green: your questions answered
Who is the fire and rescue service for Woodcote Green?
Woodcote Green is in the area of London Fire Brigade. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Can you work in Woodcote Green outside opening hours?
Yes, evening, overnight and weekend work is normal for us. That way a site in Woodcote Green does not have to lose a day’s trading. Your opening times are the first thing we ask for.
How regularly do grease filters need exchanging?
The right interval depends on the kitchen. If filters are dripping or clogging before the next change, it’s too long and we will adjust it.
Does the law say we must follow TR19?
No. The law sets the duty; TR19® is the benchmark used to show it’s met. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person has to manage fire risk, and without records, many insurers may refuse or reduce a claim.
Is there a survey before the work?
Yes. Every job is surveyed first, from your pictures and details, or with a visit where needed. Then you get a fixed quote.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line, for problems that cannot wait. Call us any time and explain what’s happened.
Are you fully insured?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
Do you recommend a next date?
Yes. Every report includes a recommended date for the next visit, based on what we found and how the system is used.
Part by part
Baffle filters
In a baffle filter, the air zigzags through metal baffles. Grease drops out as it does.
The plenum
Clean filters reduce the grease reaching the plenum, but it’s still cleaned during a full TR19 clean.
Kitchen extracts in Woodcote Green
According to Food Standards Agency records, there are about 10 pubs and bars in Woodcote Green and the streets around it, up to about 1.5 miles out. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Night work suits London kitchens, and roads and loading bays tend to be quieter too. Environmental health officers from Sutton council inspect food businesses in Woodcote Green. 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.
A hospital like Queen Mary's Hospital For Children, about 1.1 miles north-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day. A hall kitchen that only cooks for events, whether near St. Patrick's Church or elsewhere in Woodcote Green, still needs its extract cleaned, just less often.
Woodcote Green is about 1 mile west of Purley, in Greater London.

Fixed quotes for grease filter exchange in Woodcote Green
Before we fix a price, we need to know a few things. We look at:
- Whether several sites go on one quote
- When the work can happen, such as evenings, overnight or weekends
- Whether it’s a one-off visit or part of a schedule
- Where the site is and how we reach it
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote and give you a fixed price before work begins.
What to send for a quote
A few details help us quote accurately. With your enquiry, please include:
- Problems your staff have spotted
- A few general shots of the system
- Any previous report or certificate
- Close-ups of filters, grilles, hatches or access panels
There’s no standard price list, because every site is different. We look at your system first, from photos or on a visit, then send a fixed quote. To get going, phone us on 0345 646 2711 or use the quote form.
Keeping the system healthy
No system stays clean for ever, but care slows the build-up. A few tips:
- Clear anything stored on or near the canopy
- Wipe the outside of the canopy as part of daily cleaning
- Let us know if your cooking hours increase
- Keep the extract on whenever the range is in use
We tell you if we spot anything in the canopy that needs attention. That might mean bringing a TR19® clean forward, and we can arrange it.
If filters are already dripping, they’re overdue. A clean set straight away cuts the grease in the canopy and the plenum may need a clean as well.
Do you need grease filter exchange in Woodcote Green?
Hand-washed filters often come back still greasy. Grease lodges deep in baffles and mesh, and a quick rinse leaves it there.
These are the problems we see most often:
- Filters that leave gaps in the canopy
- Smoke and heat lingering under the hood
- Grease filters clogged with grease
- Missing filters in the filter bank
Term dates shape school work: for a school like Wallington High School for Girls, an extract clean fits neatly into a half-term or summer break.
