Questions from Coldharbour
Who is the fire and rescue service for Coldharbour?
It’s London Fire Brigade, which covers Coldharbour. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Can a school canteen extract in Coldharbour be done out of term time?
Yes. The holidays are the usual time for school work. There are about 21 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Coldharbour. You can phone us on 0345 646 2711, or email photos with the dates the site is empty.
Is there a survey before the work?
Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
Are you accredited?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We’re fully insured and have been trading since 2009.
Can you price the work without visiting?
Often, yes. With good photos, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
How long does it take to clean extract ducts?
It depends on the length of the duct, the number of access panels and how much grease there is. Typically it takes a few hours for a short run, longer for long runs and tall risers.
Will the duct clean disrupt the kitchen?
Out of hours, at a time that suits the kitchen. Long ducts can be split across visits, with the kitchen ready to cook each morning.
What shows that the ducts need a clean?
The date on the last certificate is the first thing to check. If it’s overdue, or there is not one, a clean is due, and grease readings will confirm how urgent it is.
About our ductwork cleaning in Coldharbour
Not every duct has enough access panels. TR19 calls for any section we couldn’t reach to be recorded, and new panels can be fitted to reach it in future. It’s better to know than to assume. If you are dealing with readings above 200 microns from a grease thickness test and thick deposits at the bottom of a vertical duct, we can put it right.
In a London area like Coldharbour, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. Grease in a duct like that is a fire risk to the whole building, not just the kitchen, so a regular TR19® clean protects everyone in it.
Think of the report as the system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Coldharbour kitchens: local notes
The FSA’s data shows about 18 bars, pubs and nightclubs registered across Coldharbour and its immediate surroundings (about a mile and a half). Any of them serving cooked food has an extract to keep clean, from canopy to discharge. London Fire Brigade covers Coldharbour. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. In London, kitchens are typically cleaned overnight, when the kitchen is closed and loading is easier.
If you run catering at a healthcare site, such as a hospital like Eltham Community Hospital about 1.3 miles north, the extract may need cleaning more often than a part-time kitchen. For kitchens close to Mottingham station, where the day often starts early and ends late, the extract can be cleaned overnight. Where a hall near St Alban, or anywhere in Coldharbour, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

The process
We start by comparing what we find with the survey or your pictures. Anything unexpected is raised with you before we go further. From there, it takes a shift or more, depending on the length of the runs and the number of access points. In a London area like Coldharbour, parking, loading and building access are planned before the day of the work.
- First the duct route is traced and every access point noted.
- Set points along the runs are tested for grease.
- Access panels are opened and heavy deposits scraped out by hand.
- Next the ducts and risers are degreased, using whatever suits the deposit.
- Readings and pictures are repeated and any section we couldn’t reach is recorded.
Getting ready for the visit
- Have your last certificate or report to hand
- Tell us about site rules, permits or sign-in

What affects the quote in Coldharbour
Sites vary more than people expect. What affects the quote:
- The number of sites or systems
- How easy every part is to reach
- The condition of the system
- Site requirements such as sign-in and permits
Working hours, access and the scale of the site can all change the price. We take each of them into account, and the price is fixed before we start.
Helping us quote
To speed up the quote, send us:
- Where the site is and what kind of site it is
- How we’d reach plant on a roof or in a plant room
- Any access panels or hatches you can see
- Your opening hours and when the area is out of use
Quoting starts with a diagnosis, from your photos and details or, where that is not enough, a survey on site. Then we send a fixed price, before we start.
Multi-site and managed buildings
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.
Why act early in Coldharbour
TR19® isn’t law, but the duty to manage fire risk is. The Fire Safety Order 2005 makes the responsible person assess and reduce fire risk, and grease in the duct is part of that. Every month a London system goes without attention adds to what has to be done later.
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. You will have a fixed price before any work starts.

What a clean will not put right
We’d rather tell you now than book work that will not help, so these are the things it won’t cover:
- Faulty fire dampers
- A failed fan motor at the end of the duct (a fan repair job)
- Ductwork that’s corroded, split or holed (that needs a ductwork contractor)
If in doubt, call us on 0345 646 2711, or send details by email and we’ll say what we think.
Where we work
- Bends and junctions
- Horizontal duct runs
- Vertical risers

In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Different parts, different methods
Attenuators and discharge
Near the discharge, the air has cooled the most, which can mean heavier deposits. We include it in the clean and the readings.
Vertical risers
Cleaning a riser needs access along its height. Any part that can’t be safely reached is recorded.
