For food producers, the grease trap schedule should follow the volume going through it. Environmental health officers from Welwyn Hatfield council inspect food businesses in Welwyn Garden City.

How we handle grease trap cleaning in Welwyn Garden City
A grease trap is the kitchen drain’s first line of protection. Kept clean, it does its job quietly but left too long, it causes trouble. Routine cleaning keeps it in good working order. The work covers restaurants and takeaways, under-sink grease traps and pot wash sinks, and the jobs we see most are a bad smell from the sinks or drains and an overdue grease trap.
For a kitchen in a town like Welwyn Garden City, a deep clean is often booked after a refit, before an inspection or alongside an extract clean, so the whole kitchen is done in one closure.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

In-house cleaning or a specialist?
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
What we do, step by step
Your staff do not need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. Sites in a town like Welwyn Garden City rarely need to lose trading hours, as the work fits around them.
- We locate the trap and check how it’s fitted.
- Sinks feeding the trap are taken out of use.
- Grease and solids are removed from the trap.
- We clean every part of the inside.
- The trap is refitted, tested with water and the waste taken away.
How to prepare
- Name a contact who can let us in at the agreed time
- Find the previous report, if there is one
- Tell us where we can park and unload

Part by part
Baffles and outlets
The baffles hold back grease while water flows on. Grease clings to them so they’re cleaned every time.
Under-sink grease traps
Small grease traps sit under the sink. They fill quickly and need regular cleaning.
When it’s something else
In fairness, some problems need a different fix:
- A unit that cannot cope with the kitchen’s output
- Leaking pipework or sink wastes, which need a plumber
- Grease deep in the drains, which needs jetting by a drainage contractor
Not sure which it is? You can ring 0345 646 2711 or send us an email and we will tell you honestly.

Aftercare tips
After the visit, a few habits help the work last:
- Tell us if your menu or hours change
- Avoid pouring boiling water down to shift grease
- Report slow or smelly sinks early
- Fit sink strainers to catch food scraps
Scrape plates into the bin before washing up. Sink strainers help catch solids so less solid waste gets through.
An overfull trap lets grease pass. Regular emptying keeps it working and avoids a blockage.
What affects the cost of grease trap cleaning
There’s no set price list, because sites vary so much. What we look at:
- Access, including roofs, risers and ceiling voids
- Working hours and out-of-hours timing
- Travel, parking and unloading
- How big the system is
Working hours, access and the scale of the site can all change the price. We take each of them into account and give you a fixed price before any work starts.

Common questions in Welwyn Garden City
Can school kitchens in Welwyn Garden City be cleaned in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. There are about 21 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Welwyn Garden City. You can call 0345 646 2711 or use the quote form with the dates the site is empty.
Who inspects food businesses in Welwyn Garden City?
That’s Welwyn Hatfield council, whose environmental health officers carry out food hygiene inspections in Welwyn Garden City. Keep the dates of your last deep clean and grease trap visit with your food safety records, ready if an officer asks.
How much time does a grease trap clean need?
Most grease trap cleans take a short visit for a small trap and longer for an inline unit or interceptor including checking it drains. We plan the visit around your service.
Do you clean under-sink and inline grease traps?
Under-sink and inline grease traps, and larger interceptors. Each one is emptied, cleaned and checked in the same careful way.
Do I get a report after the visit?
Yes, always. The report is dated and includes pictures, and TR19® Grease cleans come with a certificate through the BESCA VHE portal. Keep it in your maintenance log.
What do you do with what you remove?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. We don’t leave it behind.
Can you clear our blocked drains as well?
That depends on the cause. If the trap is full, cleaning it often helps but grease set further down the drains needs jetting by a drainage specialist.
Do the sinks have to be out of use during the clean?
While the trap is being cleaned, nothing can drain into it. That’s why we time visits around service so the kitchen isn’t held up.
Signs you need grease trap cleaning in Welwyn Garden City
A full trap cannot hold any more grease. It then builds up in the drains and the sewer beyond, where it can form blockages.
Look out for these warning signs:
- An interceptor full of grease and solids
- Gurgling drains in the kitchen
- A small trap that fills too quickly
- Drains clogged with fat
If you run a church or community hall kitchen, near Church Of Saint Francis Of Assisi or elsewhere in Welwyn Garden City, a deep clean and an emptied grease trap before a busy season of events are worth booking.
