Ductwork cleaning in Blackheath, done properly
Once air leaves the canopy, it travels through ductwork that most people never see. Grease settles along every metre of it, and that’s where a kitchen fire can travel. Our ductwork cleaning reaches inside the runs and risers through access panels, to BESA TR19® Grease. The work covers access panels, multi-storey ducts and bends and junctions, and common reasons people get in touch are readings above 200 microns from a grease thickness test and sections of duct with no access panels.
In a small place like Blackheath, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. We agree access and timings in advance.
Accreditations are easy to claim and worth checking. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Aftercare tips
Think of this as the after-treatment advice, short and simple:
- Ask us about extra access panels where sections can’t be reached
- Never cook with a filter missing
- Do not block access panels with shelving or stock
- Keep your cleaning records together
Access panels are closed and sealed back up after cleaning, and the surrounding area is left clean. Waste grease and water are taken away.
The less grease gets past the canopy, the cleaner the duct stays. Keep the filters clean, well fitted and in place whenever you cook.
Ductwork cleaning in Blackheath: the local picture
It’s Waverley council that sends environmental health officers to food businesses in Blackheath. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Before-and-after pictures from each clean are a simple way to show the extract is in hand. Blackheath, about 27 miles from central London, is within our usual area. We work evenings, overnight and at weekends, so the visit fits around the site.
If you run a church or community hall kitchen, near Church of St Martin or elsewhere in Blackheath, its extract still collects grease from every lunch and event. A hospital like St. Luke’s Hospital, about 2.6 miles north-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

What ductwork cleaning can’t fix
We’d rather tell you now than book work that will not help, so these are the things it won’t cover:
- A damper stuck open in the duct
- Duct sections that need replacing
- Sections that cannot be reached safely without new access (those are recorded, and panels can be fitted)
Not sure which it is? You can call 0345 646 2711 or use the quote form and we’ll tell you honestly.

What affects the cost of ductwork cleaning
Before we fix a price, we need to know a few things. We look at:
- Access, including roofs, risers and ceiling voids
- Site requirements such as sign-in and permits
- The number of sites or systems
- Parking and loading at the site
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you’re unsure, call 0345 646 2711, or send details by email and we will give you an honest view and a fixed quote.
What we need to know
Before you ask for a quote, gather:
- The roof, plant room or outside wall the system runs to
- Any previous report or certificate
- Any symptoms, from odd noises to smells or leaks
- The postcode and the type of business
Quotes are quick. Send a few details and photos, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
Staff cleaning versus specialist work
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.

The process
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. The visit takes a few hours for a short run, longer for long runs and tall risers. Seeing the system in photos first means the trip to Blackheath can be planned properly.
- We trace the duct and find every way in.
- We take grease readings along the route.
- Out of hours, the area is protected and the access panels opened.
- Thick grease is scraped out, then the runs and risers are degreased.
- Panels are closed, readings and pictures repeated, and unreachable sections recorded.
Getting ready for the visit
- Dig out any earlier paperwork for the system
- Mention any parking or loading restrictions
- Clear the space around the work
Getting a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.

Common problems we fix in Blackheath
Damaged or poorly fitted filters let more grease into the duct. More grease reaches the ductwork than it should and it fills faster.
Signs it’s time to call us include:
- A grease test showing the duct is overdue
- A duct nobody has opened in years
- An insurer asking for TR19 evidence
- Grease pooling at the foot of the riser
Commuter trade near Chilworth station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.
Questions to ask before you book
- What paperwork you get at the end
- Proof of accreditation you can verify
- When they can work, and whether that is outside your opening hours
- Whether the figure could change on the day
FAQs for Blackheath
Who inspects food businesses in Blackheath?
Food hygiene inspections in Blackheath are carried out by Waverley council. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Is Blackheath within the area you cover?
Yes. Blackheath is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
Are you fully insured?
Yes, we are fully insured. We also hold CHAS and SafeContractor, for sites that check contractor safety.
Are you accredited?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Do you survey before quoting?
Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need, and the quote is based on that.
Can extra access doors be added to the duct?
Yes, we do. We’ll point out where panels are needed, and we can fit them so those sections are cleaned in future.
How much does ductwork cleaning cost in Blackheath?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote and we will normally reply within one working day.
Can we book visits on a schedule?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. Each report recommends when the next visit should be.
Leave it or put it right?
A fire in a greasy duct is hard to reach and hard to stop. The duct can carry it to rooms, floors or roof spaces well away from the kitchen, which is why the duct matters as much as the canopy. In a small place like Blackheath, a system that fails can take a site out of use.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll explain each part.
