About our grease trap cleaning in Hatfield
In Hatfield, we time grease trap visits so the sinks are not needed. We empty, clean and check the trap, and the waste is taken away. It can be booked on its own or alongside other kitchen work. If you have an overdue grease trap and a routine grease trap service, we can put it right.
Kitchens in a town like Hatfield often book a deep clean alongside their extract clean, which keeps the disruption to a single night.
Good records are part of the job. Each visit is written up with photos, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

What a clean won’t put right
In fairness, some problems need a different fix:
- A trap undersized for the amount of cooking
- Drains that need jetting rather than trap cleaning
- Sewer problems outside the premises

Leave it or put it right?
A full grease trap lets grease through to the drains. It hardens on the pipe walls, until the drain blocks. Regular trap cleaning beats dealing with a blockage. If an inspection, an insurer’s survey or a fire risk assessment is coming up in Hatfield, having the work done and recorded first helps.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you are not sure what’s needed, call us on 0345 646 2711 or drop us a line for straight advice and a fixed quote.

FAQs for Hatfield
Which environmental health team covers Hatfield?
In Hatfield, it’s Welwyn Hatfield council that carries out food hygiene inspections. An officer may look behind equipment and at drains, so it pays to have the deep clean booked before those areas build up.
Can school kitchens in Hatfield be cleaned in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. There are about 18 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Hatfield. Just ring 0345 646 2711, or email photos with your term dates and we’ll plan around them.
Do the sinks have to be out of use during the clean?
For the length of the clean, yes. The clean takes a short visit for a small trap and longer for an inline unit or interceptor and we book it around your service.
What about areas you can’t get to?
The report shows them clearly. In ductwork, new access panels are often the answer, and we can fit those.
Which kinds of sites do you work on?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
How often should a grease trap be cleaned?
The right interval depends on your trap and your cooking. Slow or smelly sinks between cleans mean it needs doing more often, and we can shorten it.
Which records should we keep?
Anything that proves the system is maintained: our reports and pictures, any certificates and your in-house logs. One maintenance log per site keeps it simple.
What problems does a full grease trap cause?
Grease and food waste build up until the trap stops working. The result is slow drains, foul odours and eventually a blockage.

Grease trap cleaning in Hatfield: local notes

Fat from washing up sets hard in pipes, and kitchens like these produce plenty of it. Food hygiene inspections in Hatfield are the job of Welwyn Hatfield council’s environmental health team. Walls, floors, ceilings and equipment are all part of what they look at. Keeping a record of deep cleans and grease trap visits helps at inspection time.
Queen Elizabeth II Hospital, about 2.4 miles north-east, is the nearest hospital to Hatfield; healthcare kitchens can’t stop cooking, so deep cleans are worked around meal times.

Aftercare tips
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Book trap cleans at a set interval
- Get food waste into the bin, not the sink
- Keep strainers in every sink
- Tell us when sinks start draining slowly
Collect waste cooking oil separately rather than pouring it down the sink and the trap won’t fill as quickly. It’s the single easiest way to help.
More cooking means more grease in the trap. Shortening the cleaning interval now stops it overflowing.
Managing agents and facilities teams in Hatfield
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
From a single site to a large estate, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
What we do, step by step
There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and photos. Most of the time goes on the work itself, which takes an hour or so for an under-sink trap, longer for a larger unit. A closed day, an evening or an early start: whichever suits your site in Hatfield, we will book around it.
- First, we locate the grease trap and look at the pipework around it.
- The sinks feeding the trap are kept out of use while we work.
- Built-up fat, oil and grease is removed from the trap.
- We clean the chambers, baffles and connections.
- The trap is reassembled, checked for leaks and the waste taken away.
Preparing for the visit
- Mention any locked doors, roof access or ceiling voids
- Plan for cooking equipment or plant to be off before we arrive
- Arrange a key holder or contact on site
Ask for a quote
Here’s what helps us quote: where the site is, what it is and its opening hours, pictures of the system and the last certificate or report, if there is one. Once you have those, ring 0345 646 2711, or send details by email.

What your team can do, and what needs us
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
