About our grease trap cleaning in Bell Bar
Grease is behind most blocked kitchen drains. Down the line, they can add to fatbergs in the sewer. A well-maintained trap holds them back. If you are dealing with drains clogged with fat and a grease trap that hasn’t been emptied in a long time, we can put it right, from pot wash sinks, school and care home kitchens and under-sink grease traps onwards.
In rural areas, a kitchen may drain to a private system rather than a public sewer, and fat getting past a grease trap can cause real trouble there.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

How it works
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before work begins, and floors and nearby surfaces are sheeted. On site, it takes an hour or two in most kitchens, depending on the size and condition of the trap. In a small place like Bell Bar, the journey is planned ahead and the visit arranged around the site’s hours.
- We find the trap and check how it’s connected.
- We ask for the sinks that drain into the trap not to be used.
- We take out the layer of fat, oil and grease and any solids.
- Every part of the trap is scraped and cleaned, including the baffles.
- We put it back together, run water through and remove the waste.
Before we arrive
- Mention any parking or loading restrictions
- Tell us about site rules, permits or sign-in
- Move anything stored near the system

What the work involves, part by part
School, care home and staff kitchens
Kitchens with fixed mealtimes build up grease more predictably. Planned cleaning fits their routine.
Grease interceptors
Grease interceptors are larger units that serve busier kitchens. They hold more grease and solids but they still need cleaning.
Common questions in Bell Bar
Can you come to Bell Bar after we close?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Bell Bar needn’t be disturbed. Let us know the hours you are closed and we will book within them.
Which council inspects kitchens in Bell Bar?
The local authority for Bell Bar is Welwyn Hatfield council, and its environmental health team does the inspecting. An officer may look behind equipment and at drains, so it pays to have the deep clean booked before those areas build up.
What do you do to protect the area?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
Is TR19 cleaning required by law?
Not in itself. Insurers, fire officers and EHOs look to TR19® as the benchmark, and many insurers ask for proof of cleaning to it. The legal duty sits in the Regulatory Reform (Fire Safety) Order 2005, which applies in England and Wales.
Do you offer emergency callouts?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
Will you tell us when the next visit is due?
Yes. The recommended date is on the report. BESA’s minimum intervals for kitchen extracts range from 3-monthly for heavy use to 12-monthly for light use, while fire dampers are tested at least annually.
How far ahead should we book?
Book as early as you can for planned work, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
Why does a grease trap need regular cleaning?
Once it’s full, grease passes straight through. It then sets in the drains, causing blockages and smells and can end up adding to sewer blockages.

Why deal with it now?
Grease that gets past the trap does not disappear. It can build up in the drains and join fatbergs in the sewer. A well-maintained trap keeps it where it can be removed. If the system at a site near Bell Bar fails, there may be nowhere nearby to move to.

Looking after it afterwards
Think of this as the after-treatment advice, short and simple:
- Keep the grease trap on a regular cleaning schedule
- Keep access to the trap clear
- Scrape plates and pans into the bin before washing up
- Act on gurgling or smelly drains
You will get our view on how often the trap needs cleaning. It’s based on how full it was and how much the kitchen cooks.
Grease that gets past the trap sets in the drains. Once it’s there, it needs a drainage contractor to clear so prevention is the easier route.
Grease trap cleaning around Bell Bar
The FSA’s data shows about 3 pubs and bars registered within about 1.5 miles of central Bell Bar. Wherever they cook, the kitchen and its drains need the same attention as a restaurant’s.

- The paperwork from the last visit, if you have it
- How we’d reach plant on a roof or in a plant room
- Any symptoms, from odd noises to smells or leaks

In-house cleaning or a specialist?
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
