Grease trap cleaning for kitchens and businesses in Woolmer Green
Smells from the sink, gurgling drains or slow drainage all point to the grease trap. We find the trap, empty it and clean it and run water through to check it drains. The work covers pot wash sinks, school and care home kitchens and restaurants and takeaways, and the jobs we see most are an under-sink unit that needs regular emptying and a full, neglected grease trap.
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.
Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

What your team can do, and what needs us
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Staff cleaning does not 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.

Aftercare tips
Here’s the after-treatment advice, short and simple:
- Never pour used oil down the sink
- Keep strainers in every sink
- Mention any increase in cooking
- Scrape plates and pans into the bin before washing up
You will get our view on how often the trap needs cleaning. It’s based on how full it was and how busy the kitchen is.
A fixed cleaning interval means the trap never gets overfull. We agree the timing with you.
Honest limits
A few issues sit outside what this work can do:
- Blockages further down the drainage network
- Broken pipework below ground
- Grease deep in the drains, which needs jetting by a drainage contractor
If you’re not sure, just call us on 0345 646 2711 or send us an email and we will give you a straight answer before you book.

Common problems we fix in Woolmer Green
Food scraps go down the sink with the washing-up water. It settles in the trap as solids and fill it from below.
If you notice any of these, it’s worth a diagnosis:
- A full, neglected grease trap
- An inline trap or interceptor due for cleaning
- A small trap that fills too quickly
- Washing-up water that will not drain away
Knebworth House, about 2 miles north-west, is one of the historic houses around Woolmer Green; event kitchens at places like that work in bursts, so a deep clean after a busy season helps.

Woolmer Green kitchens: local notes
The FSA’s food hygiene register shows about 13 restaurants, cafés and works canteens and about 4 takeaways and sandwich shops in and around Woolmer Green, up to about a mile and a half out. Each of them sends fat, oil and grease towards the drain, which is why grease traps need regular emptying. It’s Welwyn Hatfield council that sends environmental health officers to food businesses in Woolmer Green. The state of floors, drains and hard-to-reach corners all feeds into the inspection. Photos and dates from each deep clean make a useful record.
Healthcare kitchens, like those at hospitals such as Queen Elizabeth II Hospital (about 4.8 miles south), cook for long hours, so deep cleans and grease trap work are planned around patients’ meals. School kitchens, at schools like St Michael's Woolmer Green CofE VA Primary School for example, typically have their deep cleans and grease trap work done while the canteen is closed.

Landlords, agents and facilities managers
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we will send a fixed quote.
The process
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before we start, and floors and nearby surfaces are sheeted. The work itself takes less than an hour for many under-sink units. Rural roads and tight entrances are worth telling us about before a visit to Woolmer Green.
- We agree a time when the sinks aren’t needed.
- The trap is opened up and checked.
- Built-up grease and food waste are taken out.
- The inside, baffles and outlet are cleaned.
- We close it up, check it drains and suggest when it needs cleaning again.
Preparing for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Let us know about parking and loading
- Make sure equipment near the work can be switched off and left to cool
