Multi-site and managed buildings
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
TR19 kitchen extract cleaning in Northumberland Heath

We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001 and are fully insured.

Searching for commercial kitchen extraction cleaning in Northumberland Heath? Duct Doctor has covered London and the South East since 2009, as a BESCA Vent Hygiene Elite member.
The fire risk in a kitchen extract sits in the parts nobody sees: the plenum, the duct and the fan, which is why a TR19® clean in Northumberland Heath goes well beyond the canopy.
London kitchens are often tucked into basements or the back of a building, with extract ducts that can climb several floors to discharge at roof level. For a kitchen in Northumberland Heath, that typically means a longer system to clean and more access panels to plan around.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What affects the cost of kitchen extract cleaning
There’s no set price list, because no two systems are the same. The quote depends on:
- The condition of the system
- The times the site is available
- How easy every part is to reach
- Site rules, permits and inductions
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at, and you’ll get one fixed quote.
What to send for a quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Photos showing the whole system and its surroundings
- Where the site is and what kind of site it is
- Problems your staff have spotted
- Your opening hours and when the area is out of use
To help us quote: the address, the type of site and when it’s open, a few photos and the last certificate or report, if there is one. Then call us on 0345 646 2711, or email photos.
In-house cleaning or a specialist?
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
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, alongside our reports.
Grease, kitchens and Northumberland Heath
The FSA’s food hygiene register includes about 34 pubs, bars and clubs within 1.5 miles or so of the middle of Northumberland Heath. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. London jobs normally start after the last service, with loading and roof access agreed with the building first. London Fire Brigade covers Northumberland Heath. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
School kitchens, at schools like King Henry School for example, are typically cleaned in the holidays so no lunches are lost. If you cook for passing trade around Barnehurst station, the extract can be cleaned between your last and first customer.
Northumberland Heath is about 3 miles north-west of Dartford, in Greater London. Every kind of commercial site in Northumberland Heath, kitchen extract cleaning is something we can help with. We can work out of hours so the site keeps running. Northumberland Heath is one of 764 places in Greater London where we work for commercial clients. Our London page covers sites nearby (11 miles or so).

Local landmarks in Northumberland Heath
Typical jobs here are in premises near Trinity School, The Royal Oak pub and Braeburn Park. The nearest railway station is Barnehurst station, about 0.6 miles south-west of the centre. Well-known places in the area include Erith Museum (0.7 miles north-east) and Erith and District Hospital (within half a mile north). The countryside around Northumberland Heath includes Crossness Nature Reserve.
Why deal with it now?
Grease that is left only gets thicker. Under BESA guidance, grease shouldn’t exceed a mean of 200 microns between cleans, and 500 microns or more at any point needs immediate spot cleaning. The longer it’s left, the bigger the job becomes. In Northumberland Heath, a planned overnight visit is much easier than closing unexpectedly.
The cost depends on how big the system is, what state it’s in and how easy it is to reach. We give you a fixed price before any work starts, so you know where you stand.

How the visit works
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. All told, the work takes a single shift for most kitchens, with long duct runs and tall risers needing more time. In a London area like Northumberland Heath, parking, loading and building access are planned before the day of the work.
- First the diagnosis: a survey of the whole system and its access points.
- We record grease levels at set points, then fix the price.
- After the kitchen closes, we sheet the area and set up to contain grease and water.
- Heavy deposits are scraped by hand and the system degreased to TR19® Grease.
- Then the clean bill of health: readings, a TR19 certificate and a photo report with the next date.
Getting ready for the visit
- Arrange a key holder or contact on site
- Have your last certificate or report to hand
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Advice
Northumberland Heath: your questions answered
Who carries out food hygiene inspections in Northumberland Heath?
That’s Bexley council, whose environmental health officers carry out food hygiene inspections in Northumberland Heath. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Who is the fire and rescue service for Northumberland Heath?
It’s London Fire Brigade, which covers Northumberland Heath. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
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.
Do you cover Northumberland Heath?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, and that includes Northumberland Heath.
How often should a kitchen extract be cleaned?
It depends on how many hours a day the kitchen cooks. Heavy use of 12 to 16 hours a day calls for a clean at least every 3 months under BESA guidance, and lighter use less often. Your report gives a recommended next clean date.
Can you come out in an emergency?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
What do you need from me for a quote?
Only a few details: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. Then phone us on 0345 646 2711, or email photos.
What’s TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not legislation, but it’s the standard people check against.
Do you need kitchen extract cleaning in Northumberland Heath?
Hours of cooking are the biggest factor. Under BESA guidance, heavy use of 12 to 16 hours a day means a clean at least every 3 months, moderate use every 6 months and light use every 12. They are minimums: measured grease levels set the real interval.
Most sites get in touch when they notice something like this:
- A TR19 certificate needed for the insurer
- Fat running down the canopy edge
- A new tenancy or takeover with no cleaning history
- An inspection that picked up a dirty extract
A hospital like Erith and District Hospital, about less than half a mile north, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
