How we handle grease trap cleaning in Mackerye End
Grease traps sit between the sinks and the drain, holding back fats, oils and grease. As the waste water cools, the grease floats and stays in the trap while the water carries on to the drain. Over time, the trap fills up and has to be emptied and cleaned. The work covers restaurants and takeaways, inline grease traps and school and care home kitchens, and people most often call us about gurgling drains in the kitchen and an under-sink trap that keeps filling up.
For a kitchen in or near Mackerye End, 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.

How the job changes from site to site
Baffles and outlets
The outlet carries the separated water on to the drain. If it’s blocked or greasy, the trap backs up.
Under-sink grease traps
Under-sink traps are compact units fitted below the kitchen sink. They fill quickly, so they need frequent emptying.
Keeping the system healthy
Aftercare is simple, and it makes the next visit easier:
- Collect waste cooking oil separately
- Keep strainers in every sink
- Avoid pouring boiling water down to shift grease
- Don’t store things on top of the trap
Between cleans, keep food scraps out of the sink. Sink strainers help catch solids before they reach the trap.
A fixed cleaning interval means the trap never gets overfull. We agree the timing with you.
How the visit works
Your staff don’t 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 we take it from there. Before we leave, the area is tidied and the paperwork follows. Somewhere like Mackerye End, lanes, gates and parking are worth mentioning in advance.
- We agree a time when the sinks are not needed.
- We open the trap and look at its condition.
- Built-up grease and food waste are taken out.
- We clean the baffles, inlet and outlet.
- The trap is closed, tested and the next clean discussed.
How to prepare
- Let us know when the site is closed or quiet
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Tell us about site rules, permits or sign-in
Ask for a quote
Every quote begins with a look at the system, from your photos and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work so you know the cost before any work starts.

In-house cleaning or a specialist?
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
FAQs for Mackerye End
Can a school kitchen in Mackerye End be done out of term time?
Yes, out-of-term visits are normal for schools. The FSA’s register shows about 5 schools and colleges with food registrations within roughly a mile and a half of Mackerye End. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Which council inspects kitchens in Mackerye End?
Kitchens in Mackerye End are inspected by St Albans City council’s environmental health officers. Photos from a deep clean are a simple record of what was done and when.
Which kinds of sites do you work on?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
How far ahead should we book?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
Do you provide a certificate or report?
Yes, on every job. It’s a dated, written report with photos, plus a certificate via the BESCA Vent Hygiene Elite portal for TR19® Grease cleans. File it with your fire safety records.
How do you protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
Can you come out in an emergency?
Yes. Our emergency line runs 24/7, for problems that can’t wait. Ring any time and tell us what’s happened.
Will cleaning the grease trap fix a blocked drain?
A trap clean removes the grease in the trap, and can clear the problem where the trap was the cause. A blockage deeper in the drains needs a drainage specialist.
When to call us in Mackerye End
Waste cooking oil poured down the sink fills a grease trap far faster than washing-up. Even small amounts add up.
The symptoms we are asked about most include:
- A kitchen drain that smells
- Grease setting in the kitchen pipework
- Gurgling drains in the kitchen
- An under-sink unit that needs regular emptying
Healthcare kitchens cook through the year, so a deep clean has to be fitted around meals; St Albans City Hospital, about 4.8 miles south, is the nearest hospital to Mackerye End.
