Kitchen extract cleaning in Bush Hill, done properly
The ducts are where most of the grease hides. We reach horizontal runs and vertical risers through access panels, scraping heavy deposits by hand before degreasing. Anything out of reach is noted in the report, and new panels can be fitted. Common call-outs are for fat running down the canopy edge and an overdue clean flagged by an EHO or fire officer, across extract fans, discharge points and plenums and filters. Kitchen extract cleaning, TR19 cleaning, extraction cleaning: whatever you call it, it’s the job we do every week across Greater London.
We clean every reachable part of the system in Bush Hill: canopy, plenum, filters, ducts, risers and fan, and the discharge where it can be reached.
In London, few kitchens can spare a day to close, so extract cleaning in Bush Hill is usually 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, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

Aftercare tips
Think of this as the after-treatment advice, in brief:
- File each certificate with the fire risk assessment
- Refit filters properly after cleaning
- Run the extract fan throughout cooking
- Keep grease collection points emptied
A TR19 certificate notes the date, the location and the technician. File it with the fire risk assessment and the maintenance log so it’s ready when anyone asks to see it.
Clean the grease filters often, not just on clean day. A filter that’s clean and seated properly stops more grease getting into the plenum, so the ductwork stays cleaner for longer.

What else we do in Bush Hill
Common questions in Bush Hill
Which environmental health team covers Bush Hill?
Food hygiene inspections in Bush Hill are carried out by Enfield council. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Can a school canteen extract in Bush Hill be done out of term time?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 42 schools, colleges and universities with registered kitchens within about a mile and a half of Bush Hill. Just call us on 0345 646 2711 or drop us a line with your term dates and we will plan around them.
Will the clean disrupt our service?
We clean while the kitchen is closed, so evenings, overnight, early mornings and weekends are all options. Equipment needs to be off and cool before we start.
How often should a kitchen extract be cleaned?
Under BESA guidance, the minimum depends on how long you cook each day: 3-monthly for heavy use, 6-monthly for moderate use and 12-monthly for light use. Grease readings can show a shorter interval is needed.
Will my insurer ask for a TR19 certificate?
Many insurers ask for proof of regular cleaning to TR19, and many policies require it. An insurer may refuse or reduce a claim if there’s no evidence, so it’s worth checking your policy wording.
How much does kitchen extract cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote and we’ll normally reply within one working day.
What’s TR19?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.
Do you look at the system first?
Yes, every time. We diagnose before we treat: the survey shows what needs doing and what access we need and the fixed quote is built on it.
What we do, step by step
A visit follows the same order every time: sheeting and protection first, make the system safe, do the work, tidy up and hand over the paperwork. On site, the work takes anything from a few hours to a full night, depending on the size of the system. Security desks and permits-to-work are routine in London, so let us know what your building in Bush Hill needs from us.
- We survey the system, from your pictures or on site, canopy to discharge.
- Grease thickness is measured and the price is fixed before work starts.
- The kitchen is closed, the equipment cooled and everything nearby protected.
- Filters, canopy and plenum are cleaned, then the ducts, risers, fan and discharge.
- Readings are repeated, photos taken, and your TR19 certificate and photo report issued.
Before we arrive
- Let us know when the site is closed or quiet
- Make sure equipment near the work can be switched off and left to cool
- Find the previous report, if there is one

What we’re called out for in Bush Hill
In Bush Hill, as anywhere, grease gathers where the air slows down: long horizontal runs, bends, the base of risers and around the fan. The cooler the duct, the more grease drops out of the air.
If you notice any of these, it’s worth a diagnosis:
- Fat running down the canopy edge
- An extract that has never been cleaned to TR19
- Grease smells coming from the extract
- Extraction mentioned at an environmental health visit
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; St Michaels Hospital is the nearest hospital to Bush Hill, about 1.4 miles north.
What to look for in a quote
- Whether the price is fixed
- What insurance they carry
- Whether the work can be done while the site is closed
- What happens if part of the system cannot be accessed
What affects the cost of kitchen extract cleaning
A fixed price needs a few facts first. We look at:
- The scale of the work
- The condition of the system
- Working hours and out-of-hours timing
- Where the site is and how we reach it
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
Helping us quote
We can often survey from photos. The most useful are:
- Any previous report or certificate
- Detail shots of panels, filters and grilles
- Any symptoms, from odd noises to smells or leaks
- The postcode and the type of business
We don’t publish a price list, because no two systems are the same. We look at your system first, from pictures or on a visit, then send a fixed quote. To start, phone us on 0345 646 2711 or drop us a line.
What the work involves, part by part
Restaurant and pub kitchens
High-heat cooking loads the extract with grease, and measured readings show whether the minimum interval is enough.
Extract fan and discharge
Some systems have attenuators to cut noise, and they hold grease. We clean what can be reached and note anything that cannot.
What staff can safely do
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.
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.
Why deal with it now?
Grease that’s left only gets thicker. BESA guidance says the mean should not go above 200 microns between cleans, and 500 microns or more at any point needs immediate spot cleaning. Heavy build-up takes longer to remove than regular cleans. London sites work long hours, and the longer a job is left, the bigger it gets.
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 work begins.
What you get with us
- In business since 2009
- We are fully insured
- CHAS, SafeContractor and ISO 9001
- One number for every site across the South East and London

London Fire Brigade covers Bush Hill. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
