Blackheath: your questions answered
Which fire and rescue service is responsible for Blackheath?
It’s London Fire Brigade, which covers Blackheath. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Can parking be tricky for a job in Blackheath?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Where restrictions apply in the day, an evening or overnight visit typically gets round them.
Do you offer emergency callouts?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
Where does the waste go?
It’s contained and taken away. We collect grease, debris and waste water as we go, so it does not spread.
Do you survey before quoting?
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.
How much notice should we give?
For planned work, earlier is better, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
When is the ductwork cleaned?
We clean while the kitchen is closed, so evenings, nights and weekends are all possible. Equipment and the extract are switched off while we work.
Do you offer maintenance contracts?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.
Ductwork cleaning in Blackheath
Not every duct has enough access panels. TR19 calls for any section we couldn’t reach to be recorded, and we can fit new access panels so it’s cleaned next time. An honest report beats a guess. Typical jobs include proof of duct cleaning for the insurer and a duct nobody has opened in years, on bends and junctions, horizontal duct runs and multi-storey ducts.
Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, and the duct may run up through several floors before it discharges at the roof. For a kitchen in Blackheath, that normally means a longer system to clean and more access panels to plan around.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

What else we do in Blackheath
When to call us in Blackheath
Wherever the kitchen is, in Blackheath or elsewhere, the duct fills in the same way: hours of cooking, the type of food and how well the filters are kept. Under BESA guidance, the minimum interval is 3, 6 or 12 months, by daily cooking hours.
Look out for any of the following:
- Thick deposits at the bottom of a vertical duct
- An insurer asking for TR19 evidence
- Grease seeping out of the duct seams
- A grease test showing the duct is overdue
Where a hall near Church of All Saints, or anywhere in Blackheath, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
Questions to ask before you book
- Proof of insurance
- Whether the work can be done while the site is closed
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether a survey comes first
Ductwork cleaning around Blackheath
The FSA’s food hygiene register shows about 328 cafés, restaurants and staff canteens and about 146 takeaways and sandwich shops within about 1.5 miles of central Blackheath. Each kitchen that cooks under a canopy sends grease-laden air into a duct, where it cools and settles. Blackheath sits within the area of London Fire Brigade. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. In Blackheath, food businesses are inspected by environmental health officers from Lewisham council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Keeping each certificate and photo report on file helps show the extract is looked after.
If you run a café or takeaway near Blackheath station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits. Healthcare kitchens, like those at hospitals such as Greenwich District Hospital (about 1.1 miles north), often cook for long hours, which puts them in BESA’s heavier-use bands.
Blackheath is about 1 mile south-east of Greenwich, in Greater London. Blackheath gets the same approach as every site we work on: diagnosis first, a fixed price, out-of-hours working where necessary and a written report with pictures. Across Greater London, we cover 764 places, Blackheath among them.
All of SE3, SE13 and SE10 is covered for ductwork cleaning, from busy streets to back roads. Whether your site is on Pond Road, Heath Lane and Wemyss Road or a nearby road, we can help. Other places close to Blackheath include Vanbrugh Park Estate (1 mile north), Greenwich (1 mile north-west), Maze Hill (1 mile north), Lewisham (1 mile south-west) and Westcombe Park (1 mile north-east). We also work in nearby towns such as London (5 miles north-west), City of Westminster (8 miles north-west), Marylebone (7 miles north-west), Kensington (9 miles west), St Pancras (7 miles north-west) and Shoreditch (5 miles north-west).
Near you in Blackheath
We work in commercial kitchens and buildings around The Princess Of Wales Pub, Blackheath Proprietary School and Manor House Gardens and the streets around them. Blackheath has its own railway station: Blackheath station. A little further out are Lewisham Shopping Centre (1.1 miles south-west) and Royal Observatory (0.7 miles north-west). Open spaces near Blackheath include Tower Hill and Birdbrook Road Nature Reserve.
Why deal with it now?
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, including the grease inside the extract ductwork. A busy site in Blackheath builds up dirt and wear quickly, so putting it off makes the eventual job larger.
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You will have a fixed price before work begins.
Why book with us
- We’re fully insured
- Trading since 2009
- Every job surveyed first
- Out-of-hours work and a 24/7 emergency line

Managing agents and facilities teams in Blackheath
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so records stay tidy.
Keeping the system healthy
Good habits slow the build-up between visits. A few tips:
- Tell us if grease leaks from the ductwork
- Get panels fitted where the duct couldn’t be cleaned
- Check readings when the menu changes
- Keep the fan on while anything is cooking
A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. It shows when and where the clean was done and by whom.
Have access panels fitted where sections cannot be reached. It does not stop grease forming, but it stops it building unseen.
The process
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes a shift or more, depending on the length of the runs and the number of access points. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Blackheath.
- First we diagnose: the route, the access and the grease levels.
- A fixed quote follows, based on what we found.
- We clean section by section, working from panel to panel.
- We take extra care at bends and at the foot of risers.
- Readings, pictures and a recommended next clean date complete the job.
Before we arrive
- Arrange a key holder or contact on site
- Allow time for equipment near the work to be turned off and cool down
- Let us know about parking and loading
How to get a quote
We do not publish a price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, and then send you a fixed quote. To start, call us on 0345 646 2711 or send us an email.

Staff cleaning versus specialist work
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We can diagnose it and quote.
