Grease filter exchange in Orpington
An exchange visit in Orpington does not take long. We lift out the dirty filters and fit a clean set, and we check they’re seated with no gaps. If something looks wrong, we tell you. We are often asked to deal with grease left in baffles after washing and filters that leave gaps in the canopy, across baffle filters, wall canopies and school and hospital kitchens.
London kitchens tend to trade late and open early, so extract cleaning in Orpington is usually done overnight, after the last service. Before the clean, we agree loading, parking and roof access with whoever manages the building.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

The process
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. On site, the work takes less than an hour in most kitchens. Security desks and permits-to-work are routine in London, so let us know what your building in Orpington needs from us.
- We start by noting how many filters you have and what type they are.
- A change schedule is agreed to match the kitchen’s cooking hours.
- On each visit, the dirty filters come out of the canopy.
- Clean filters go straight back in, seated properly with no gaps.
- We flag any damaged filters or anything wrong with the canopy.
Getting ready for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Plan for cooking equipment or plant to be off before we arrive
- Name a contact who can let us in at the agreed time

Questions from Orpington
Which council inspects kitchens in Orpington?
Food hygiene inspections in Orpington are carried out by Bromley council. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Can you clean school kitchen extracts in Orpington during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. There are about 3 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Orpington. You can give us a ring on 0345 646 2711 or use the quote form with the dates the site is empty.
Do you offer maintenance contracts?
Yes. Send details of the systems and how they’re used and we will propose a schedule with a fixed quote.
Is filter exchange enough instead of a full extract clean?
No. Filter exchange works between full cleans, not instead of them. A TR19® clean deals with the whole system and comes with a certificate and photo report.
Are you fully insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
How long will you be on site?
That depends on the amount of work, but for many sites it takes anything from a few minutes to an hour or so, depending on the number of filters. We’ll confirm it with the quote.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
What should go in our maintenance log?
Visit reports, certificates and your in-house cleaning logs. They’re what an insurer, fire officer or EHO may ask for, so keep them together and easy to find.
What happens if it’s left?
Some kitchens in Orpington wash filters themselves to save the cost of a service, and that can work if it’s done thoroughly and on time. Where it slips, an exchange service takes the job off staff. In Orpington, a planned overnight visit is much easier than closing unexpectedly.
What you pay depends on how big the system is, what state it’s in and access to every part of it. You get a fixed price before any work starts, so there are no surprises.

What affects the cost of grease filter exchange
The survey tells us what the work involves. We look at:
- How big the system is
- The condition of the system
- Whether we need access equipment or extra panels
- Any permits to work or inductions
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account, and the price is fixed before we start.
What we need to know
When you contact us, it’s useful to have:
- Any previous report or certificate
- When the site is open and when it’s quiet
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- A few general shots of the system
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
Grease, kitchens and Orpington
Food Standards Agency records list about 102 restaurants, cafés and works canteens and about 60 sandwich bars and takeaways within roughly a mile and a half of the centre of Orpington. Swapping filters on a schedule keeps kitchens like these drawing air properly. Orpington is covered by London Fire Brigade. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Overnight is the normal time to clean a London kitchen extract, so trading isn’t affected.
Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Orpington is Orpington Hospital, about 1.5 miles south. If you run a church or community hall kitchen, near St Andrew's or elsewhere in Orpington, its extract still collects grease from every lunch and event.

Common problems we fix in Orpington
However long the kitchen cooks each day, the filters see every minute of it. Heavy daily use means fast build-up so changes need to come round sooner.
Any of these means the system needs a check-up:
- Filters left unwashed on busy weeks
- Grease filters clogged with grease
- Weak extraction at the canopy
- A canopy that drips grease
Term dates shape school work: for a school like Perry Hall Primary School, an extract clean fits neatly into a half-term or summer break.
What your quote should include
- How VAT is shown on the quote
- Exactly which parts of the system are covered
- Whether they recommend a next date
- How areas they can’t reach will be recorded
Landlords, agents and facilities managers

For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so each one has its own record.
Different parts, different methods
Mesh filters
Mesh traps grease between its layers, which makes hand-washing hard work.
Baffle filters
Baffle filters are a common choice for commercial canopies. They still need regular cleaning as the collected grease builds up between the blades.
Staff cleaning versus specialist work
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
