Ductwork cleaning in Nunhead, done properly
No two duct runs are the same, in Nunhead or anywhere else. Some run a short distance to an outside wall, others climb several floors to the roof. The survey traces the route, so we know where to get in and how long it will take. The work covers access panels, horizontal duct runs and attenuators, and the jobs we see most are proof of duct cleaning for the insurer and a duct nobody has opened in years.
In a London area like Nunhead, 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.
The paperwork matters as much as the work. Each visit is written up with photos, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

Nunhead: your questions answered
Do you work overnight in Nunhead?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Just ring 0345 646 2711 or drop us a line with your opening times and we will plan around them.
Which council inspects kitchens in Nunhead?
Kitchens in Nunhead are inspected by Lewisham council’s environmental health officers. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Which kinds of sites do you work on?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
Who is the responsible person?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: often the employer, owner or occupier. Landlords, facilities managers and managing agents can also hold responsibility.
How much notice should we give?
The more notice, the better, particularly for night and weekend visits. We typically quote within one working day, and there’s a 24/7 line for emergencies.
What does ductwork cleaning cost?
It depends on the site, so we quote each one individually. For a quote, phone us on 0345 646 2711, or email photos and tell us about the site and its opening hours.
Are you insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
Is there a survey before the work?
Yes. For many sites, pictures and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
Looking after it afterwards
Once we’ve finished, these simple steps help:
- Diarise the next duct clean
- Run the extract fan throughout service
- File each certificate and photo report in the maintenance log
- Have the grease measured if cooking hours go up
A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. It records the date, the location and the technician.
Extra access panels mean more of the duct gets cleaned each time. It doesn’t stop grease forming, but it stops it building unseen.
How the visit works
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. In a London area like Nunhead, parking, loading and building access are planned before the day of the work.
- We trace the duct and find every way in.
- We take grease readings along the route.
- Once the kitchen has closed, we protect the area and open the panels.
- Thick grease is scraped out, then the runs and risers are degreased.
- We close up, re-test, photograph and record anything out of reach.
How to prepare
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Clear the space around the work
- Let us know about permits to work or site inductions

Advice
Ductwork cleaning in Nunhead: the local picture
The Food Standards Agency lists about 71 pubs, bars and clubs and about 5 hotels and guest houses as registered food businesses in and around Nunhead, up to about a mile and a half out. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. In London, kitchens are typically cleaned overnight, when the kitchen is closed and loading is easier. Nunhead is covered by 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.
A hospital like Southwark Adult Education Institute, about 0.7 miles north, is the kind of site where a kitchen may cook for patients, staff and visitors all day. Bursars and site managers at schools such as Ivydale Primary School tend to book extract cleaning for when the kitchen is empty.

Common problems we fix in Nunhead
Grease in a duct running from a kitchen in Nunhead is as much a fire risk as in any building. Burning grease can carry fire through the ductwork to other rooms or floors, which is why the responsible person needs it under control.
If you notice any of these, it’s worth a diagnosis:
- Proof of duct cleaning for the insurer
- Readings above 200 microns from a grease thickness test
- Heavy grease at the base of a riser
- Stale grease odours from the duct
If you run a church or community hall kitchen, near Saint Antony with Saint Silas or elsewhere in Nunhead, its extract still collects grease from every lunch and event.

What the work involves, part by part
Bends and transitions
The join where the canopy meets the duct is a common hotspot. We clean it from the canopy side or through a nearby panel.
Vertical risers
Risers are cleaned through panels at different levels. Where it can’t be reached safely, the report says so.
What affects the quote in Nunhead
We do not publish a price list, because sites vary so much. The quote depends on:
- Whether it’s a one-off visit or part of a schedule
- Where the site is and how we reach it
- The condition we find in the survey
- When the work can happen, such as evenings, overnight or weekends
The cost depends on the size of the system, the condition it’s in and access to every part of it. We give you a fixed price before we start, so you know where you stand.
What to send for a quote
We can often survey from pictures. The most useful are:
- Your opening hours and when the area is out of use
- How we’d reach plant on a roof or in a plant room
- Any access panels or hatches you can see
- The postcode and the type of business
Quotes are quick. Call or email with a few details and you will typically have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
When something else is needed
A few issues sit outside what this work can do:
- An extract fan that has stopped working
- Duct sections that need replacing
- Fire dampers that don’t close (they need testing and remedials)
Not sure which it is? You can ring 0345 646 2711, or email photos and we’ll tell you honestly.
Where we work
- Attenuators
- Bends and junctions
- Vertical risers
- Multi-storey ducts
- Horizontal duct runs
- Access panels
What staff can safely do
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That is our job.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
