Ductwork cleaning in Ham
We’ve been trading since 2009, working across London and the South East. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and our certificates are issued through the BESCA Vent Hygiene Elite portal. If you are dealing with duct runs with no cleaning record and hardened, baked-on grease in long horizontal runs, we can help.
In London, few kitchens can spare a day to close, so work in Ham is normally booked for the night or the early hours. Parking, loading and access to the roof are agreed with the building before the night of the clean.
The report is your system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

When to call us in Ham
Damaged or poorly fitted filters let more grease into the duct. More grease reaches the ductwork than it should and it fills faster.
Clients normally contact us when they notice something like this:
- A grease test showing the duct is overdue
- Thick deposits at the bottom of a vertical duct
- Duct runs that cannot be reached
- Proof of duct cleaning for the insurer
School kitchens, at schools like Meadlands Primary School for example, are usually cleaned in the holidays so no lunches are lost.
Questions to ask before booking
- What insurance they carry
- Whether the work can be done while the site is closed
- What happens if part of the system cannot be accessed
- When the next visit should be, and why
What your team can do, and what needs us
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. 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, and that is where we come in.
How the visit works
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, the work takes anything from a few hours to several visits, depending on the length of duct. Getting kit into a London building takes planning, so let us know where we can load and park in Ham.
- We map the duct route and check where the access panels are.
- We measure grease thickness at set points before cleaning.
- Through the access panels, thick grease is removed by hand first.
- The duct is degreased with the method that suits the grease, from degreasers to hot water or steam.
- Readings and photos are repeated and any section we couldn’t reach is recorded.
How to prepare
- Mention any sign-in, permit or induction we need
- Have your last certificate or report to hand
- Let us know how we reach the system, including roofs, risers and plant rooms

What ductwork cleaning looks like in Ham
The FSA’s data shows about 38 bars, pubs and nightclubs registered within about 1.5 miles of central Ham. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Fire safety in Ham falls to London Fire Brigade. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. London jobs typically start after the last service, with loading and roof access agreed with the building first.
A hospital like Teddington Memorial Hospital, about 1.5 miles south-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day. If you run catering at a historic house or estate in the area (Ham House is about 0.6 miles north), event kitchens in older buildings often have awkward duct runs that need planning.
Ham is about 1 mile south-east of Twickenham, in Greater London. From the centre of Ham to the outskirts, ductwork cleaning is available to all kinds of commercial premises, from a single unit to a large public building. Ham is one of 764 places in Greater London we cover for commercial clients. London is in our area too, around 10 miles away.

What happens if it’s left?
Old grease in a duct for a kitchen in Ham does not stay soft. Heat and age turn it into a thick, stubborn crust, so the later the clean, the bigger the job. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re not sure what’s needed, give us a ring on 0345 646 2711, or send details by email and we will give you an honest view and a fixed quote.

Your questions about ductwork cleaning in Ham
Can school kitchens in Ham be cleaned in the holidays?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 21 schools and colleges with food registrations within roughly a mile and a half of Ham. Just call 0345 646 2711 or use the quote form with your term dates and we will plan around them.
Who carries out food hygiene inspections in Ham?
Kitchens in Ham are inspected by Richmond-Upon-Thames council’s environmental health officers. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
How long does ductwork cleaning take?
Allow anything from a few hours to several visits, depending on the length of duct. We will confirm the time when we quote.
Do I get a certificate for ductwork cleaning?
Readings, photos and, for a full clean, a TR19 certificate. It also gives a recommended next clean date.
Can you quote from pictures?
In many cases, yes. With good photos, the site type and your last report, we can price many jobs. Where we can’t see enough, we arrange a survey.
How much does ductwork cleaning cost in Ham?
Size, condition, access and working hours all affect the cost. Call for a fixed quote and we’ll typically reply within one working day.
How do you protect the area?
We cover floors and nearby surfaces with sheeting before we start, and waste is contained as we go. At the end, the area is cleaned down.
What’s involved in cleaning extract ducts?
Through access panels along the duct. Thick deposits are removed by hand before degreasing, such as degreasers, hot water or steam.
Between visits
To keep the system working properly between visits:
- Run the extract fan throughout service
- Store the certificate with the fire risk assessment
- Ask us about extra access panels where sections can’t be reached
- Have the grease measured if cooking hours go up
When the duct is cleaned as part of a full TR19® Grease clean, a TR19 certificate is issued through the BESCA Vent Hygiene Elite portal. It shows when and where the clean was done and by whom.
Some signs mean the duct needs attention sooner: drips from the ductwork, stale smells or a noisy fan. A grease thickness test can confirm whether a spot clean is needed.

Part by part
Horizontal duct runs
Grease settles on the floor of a flat duct run. Thick deposits are scraped out by hand before degreasing, then the walls and roof are cleaned too.
Bends and transitions
Wherever the duct turns or changes size, grease builds up. The air slows and drops its load, so these points get extra attention.
What affects the cost of ductwork cleaning
We quote each job individually. These are the things that affect it:
- The number of sites or systems
- How easy every part is to reach
- Working hours and out-of-hours timing
- Parking and loading at the site
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll explain each part.
Helping us quote
There’s no need for technical detail. It helps if you can send:
- Detail shots of panels, filters and grilles
- The postcode and the type of business
- A few general shots of the system
- The roof, plant room or outside wall the system runs to
