About our grease filter exchange in Dulwich
Think of filter exchange as routine care for the extract. Between full cleans, it keeps the airflow healthy and takes a messy task off your team. Full TR19 cleaning still comes at the right interval, with a certificate. The work covers school and hospital kitchens, island canopies and restaurants and pubs, and the jobs we see most are a canopy that drips grease and grease left in baffles after washing.
In a London area like Dulwich, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. A duct fire there can reach parts of the building far from the range, which is why keeping it clean to TR19® matters.
The report is your system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

Kitchen extracts in Dulwich
The FSA’s data shows about 52 pubs, bars and clubs and about 3 hotels and guest houses registered in Dulwich and the streets around it, up to about 1.5 miles out. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Night work suits London kitchens, and roads and loading bays tend to be quieter too. Fire safety in Dulwich falls to London Fire Brigade. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
For schools such as St Anthony's Catholic Primary School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed. If you cook for passing trade around West Dulwich station, the extract can be cleaned between your last and first customer.

Keeping the system healthy
After the visit, a few habits help the work last:
- Never leave gaps in the filter bank
- Clear anything stored on or near the canopy
- Clean the canopy surfaces regularly
- Don’t let the full clean slip because filters are changed
Keep an eye out for filters that have been taken out. A missing filter leaves a gap for grease so tell us if you need a replacement.
If filters are already dripping, they’re overdue. A clean set right away cuts the grease in the canopy and the plenum may need a clean as well.
Why deal with it now?
A filter exchange is a few minutes; a choked extract affects a whole service. It’s one of the simplest parts of looking after the system, and one of the easiest to let slip. Leaving it on a busy London site only adds to the work.
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. You will have a fixed price before any work starts.

The process
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. The middle part takes longest, which takes a short visit, depending on how many filters the canopies hold. In a London area like Dulwich, parking, loading and building access are planned before the day of the work.
- First, we record the size, type and number of filters in each canopy.
- We agree a schedule that suits how much the kitchen cooks.
- At each visit, the greasy filters are lifted out.
- We fit clean filters and check they sit snugly in the housing.
- Anything we notice, such as bent filters or a dirty plenum, is pointed out.
Before we arrive
- Clear the space around the work
- Tell us the best time to work, such as after service or at a weekend
- Name a contact who can let us in at the agreed time
Getting a quote
To get a fixed quote, phone us on 0345 646 2711, or email photos 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 typically come back within one working day.
Advice
Common problems we fix in Dulwich
Washing filters by hand does not always get them clean. Grease lodges deep in baffles and mesh and a sink wash rarely reaches it.
Signs it’s time to call us include:
- Filters that leave gaps in the canopy
- Blocked baffle filters
- Drips falling from the filters onto equipment
- Missing filters in the filter bank
If you run a church or community hall kitchen, near Christ's Chapel of God's Gift or elsewhere in Dulwich, its extract still collects grease from every lunch and event.
Questions to ask before booking
- Whether they’re fully insured
- Whether VAT is included
- Whether the price is fixed
- Proof of accreditation you can verify
Fixed quotes for grease filter exchange in Dulwich
Every site gets its own quote. This is what makes a difference:
- The scale of the work
- Site rules, permits and inductions
- Whether it’s a one-off visit or part of a schedule
- Whether several sites go on one quote
You will not find a price list here, because each job is priced on what it involves. For a fixed quote, ring 0345 646 2711, or email photos, and we will explain what it covers.
What to send for a quote
Many jobs can be priced from pictures and some basics. Useful things to send:
- When the site is open and when it’s quiet
- Where the site is and what kind of site it is
- Any access panels or hatches you can see
- The paperwork from the last visit, if you have it
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 many jobs can be priced from that alone.
Questions from Dulwich
Who would carry out a food hygiene inspection at a kitchen in Dulwich?
Food hygiene inspections in Dulwich are carried out by Southwark council. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Can you work in Dulwich outside opening hours?
Yes, out-of-hours work is a big part of what we do. The work in Dulwich can fit around your hours. Let us know the hours you’re closed and we will book within them.
What’s TR19?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t legislation, but it’s the standard people check against.
Is filter exchange enough instead of a full extract clean?
No, the two work together. A TR19® clean deals with the whole system, with a certificate and photo report.
How much does a filter exchange service cost?
The cost depends on your filters and the schedule. Just call us on 0345 646 2711, or email photos for a fixed quote, usually within one working day.
Do you have insurance?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
What about areas you can’t get to?
We record them on the report, with photos where possible, and we explain what access is needed, such as extra access panels in ductwork.
Can you look after several sites?
Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Every site has its own report.
What grease filter exchange can’t fix
An honest diagnosis matters more to us than a booking, so here’s what grease filter exchange will not do:
- Cooking smells reaching neighbours, which need odour control
- Grease behind the filters that a swap can’t remove
- A canopy too small for the cooking beneath it
If you’re not sure, just ring 0345 646 2711 or email us and we’ll give you a straight answer.

Also in Dulwich
Part by part
Mesh filters
Older or smaller canopies often use mesh filters. They can be on the same exchange schedule as baffle filters.
Baffle filters
A clogged baffle filter restricts airflow. Swapping them for a clean set restores it.
