Grease trap cleaning for kitchens and businesses in Monkswood
A neglected grease trap stops doing its job. Further down the pipe, the grease cools and hardens and the result is blocked drains and bad smells. A trap that is cleaned regularly keeps grease where it belongs. The work covers inline grease traps, school and care home kitchens and under-sink grease traps, and people most often call us about drains that gurgle and bubble and a routine grease trap service.
For a kitchen in or near Monkswood, the visit is planned ahead, around opening times and the journey, and the deep clean is the same as anywhere: walls, floors, ceilings and equipment.
The paperwork matters as much as the work. You get a written report with pictures after each visit, 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.

Common problems we fix in Monkswood
Hot washing-up water keeps grease liquid for a while. Once it cools, it sets in the pipework or the drain.
What we’re most often called out for:
- Sinks that drain slowly
- A blocked kitchen drain caused by grease
- An overdue grease trap
- Scheduled grease trap emptying
Hall and church kitchens, near The Parish Church of St John or anywhere around Monkswood, are used by many hands, and periodic deep cleans and grease trap visits keep them in order.

How the job changes from site to site
Baffles and outlets
We check the inlet, outlet and baffles at each clean so water flows freely.
School, care home and staff kitchens
Kitchens with fixed mealtimes build up grease more predictably. Planned cleaning fits their routine.
Between visits
After the visit, a few habits help the work last:
- Keep strainers in every sink
- Make sure the trap can be reached easily
- Tell us if your menu or hours change
- Tell us when sinks start draining slowly
Keep used oil out of the drains and the trap will not fill as quickly. It’s the single easiest way to help.
An overfull trap lets grease pass. Cleaning it before it’s full keeps grease out of the drains and avoids a blockage.
Landlords, agents and facilities managers
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We are happy to deal with either side and send the paperwork to whoever needs it.
Records are where multi-site compliance often slips. Each visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
What staff can safely do
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.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Why act early in Monkswood
A blocked drain can stop a kitchen in its tracks. Water won’t drain away, and dirty water can back up. Keeping the trap clean reduces the risk. Planning a trip to Monkswood ahead is easier for everyone than a rushed one.
The price reflects the work, not guesswork. That’s why we survey first, from photos or on site, and the price is agreed before work begins.

Questions from Monkswood
Can a school kitchen in Monkswood be done out of term time?
Yes, holiday work suits schools best. Food Standards Agency records list about 15 schools, colleges and universities with registered kitchens within about a mile and a half of Monkswood. Just call us on 0345 646 2711 or email us with your term dates and we’ll plan around them.
Which environmental health team covers Monkswood?
In Monkswood, 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.
How long will the sinks be out of use?
The size and state of the trap make the difference, but a clean generally takes less than an hour for many under-sink units. We will confirm when we quote.
Which records should we keep?
Everything that shows the system is looked after: reports, certificates, photos and your own cleaning or check logs. One maintenance log per site keeps it simple.
How much notice should we give?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
Does the report say when we need you again?
Yes. The report recommends when the next visit should be, based on use and what we found.
Which sectors do you work in?
Any commercial site with kitchens or ventilation, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Do the sinks have to be out of use during the clean?
Just the sinks that drain into the trap, and only while we work. Visits are booked outside your busiest hours wherever possible.
The process
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, do the work, clear away and hand over the paperwork. On site, the work takes an hour or two in most kitchens, depending on the size and condition of the trap. The timing of a visit to Monkswood is set by you, and the travel is our side of the planning.
- A visit is booked around your service.
- We open the trap and look at its condition.
- We remove the grease layer and settled solids.
- We clean the baffles, inlet and outlet.
- We close it up, check it drains and suggest when it needs cleaning again.
Preparing for the visit
- Tell us where we can park and unload
- Tell us the best time to work, such as after service or at a weekend
- Tell us about site rules, permits or sign-in
