Grease trap cleaning in Aldenham
Once a trap is full, grease passes straight through. Further down the pipe, the grease cools and hardens, leading to slow drains, blockages and smells. A trap that’s cleaned regularly keeps grease where it belongs. The work covers under-sink grease traps, school and care home kitchens and pot wash sinks, and common reasons people get in touch are sinks that drain slowly and a bad smell from the sinks or drains.
Somewhere as small as Aldenham, the kitchens that need a deep clean are typically a pub, a school, a care home or a hall kitchen, wherever there is one. Each still needs the occasional deep clean and its grease trap kept clear.
For insurers and inspectors, the record counts. That is why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What staff can safely do
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
Different parts, different methods
Inline grease traps
Several sinks may drain into one inline trap. More waste means faster filling.
Restaurant and takeaway kitchens
We time visits to avoid service so you do not lose trade.
Your questions about grease trap cleaning in Aldenham
Can a school kitchen in Aldenham be done out of term time?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 9 schools, colleges and universities with registered kitchens within about a mile and a half of Aldenham. Send us your term dates when you phone us on 0345 646 2711 or send us an email, and we will fit the work in.
Do you work at weekends in Aldenham?
Yes, we can come after you close and finish before you open. It means the site in Aldenham keeps running as normal. Just call us on 0345 646 2711 or email us with your opening times and we’ll plan around them.
What is TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
Do we lose a day’s trading?
Not typically. Visits are timed for when the area is closed, such as overnight or at a weekend, so you keep your normal hours.
Do you offer maintenance contracts?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.
How long does a grease trap clean take?
Most grease trap cleans take anything from under an hour to a few hours, depending on the trap including checking it drains. It’s booked when the sinks are not needed.
Which records should we keep?
Each report and certificate we give you, kept together in your maintenance log, along with your own cleaning log. BESA advises that certificates record the date, location and technician.
How do you keep the site clean during the work?
We start with protection: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
Grease trap cleaning around Aldenham
The Food Standards Agency lists about 7 pubs, bars and clubs as registered food businesses across Aldenham and its immediate surroundings (about a mile and a half). Wherever they cook, the kitchen and its drains need the same attention as a restaurant’s. Kitchens in Aldenham get their food hygiene inspections from Hertsmere council. The state of floors, drains and hard-to-reach corners all feeds into the inspection. Having the dates of the last deep clean to hand saves digging for them on the day.
If you cater for weddings or events at a historic house in the area (High Elms Manor is about 2.5 miles north-west), deep cleans can be fitted between bookings. Hall and church kitchens, near Church of St John the Baptist or anywhere around Aldenham, are used by many hands, and periodic deep cleans and grease trap visits keep them in order. A summer deep clean suits schools such as Fair Field Junior School, as the kitchen can be stripped back with no lunches to serve.

What affects the quote in Aldenham
The price is fixed before any work begins. It takes into account:
- The condition we find in the survey
- Site rules, permits and inductions
- Whether several sites go on one quote
- One-off work versus a regular cycle
Working hours, access and the scale of the site can all change the price. We take each of them into account, and the price is fixed before work begins.

- The postcode and the type of business
- Any symptoms, from odd noises to smells or leaks
Here’s what helps us quote: where the site is, what it is and its opening hours, a few pictures and the last certificate or report, if there is one. Once you have those, call us on 0345 646 2711, or send details by email.

What happens on the day
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with pictures. Most of the time goes on the work itself, and that takes an hour or so for an under-sink trap, longer for a larger unit. If the van will struggle with a lane or gateway near Aldenham, let us know and we’ll plan around it.
- A visit is booked around your service.
- The trap is opened up and checked.
- We remove the grease layer and settled solids.
- The inside, baffles and outlet are cleaned.
- The trap is closed, tested and the next clean discussed.
Getting ready for the visit
- Tell us the best time to work, such as after service or at a weekend
- Clear loose items from the work area
- Tell us where we can park and unload
How to get a quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
Related advice
Why act early in Aldenham
A full grease trap lets grease through to the drains. There it sets and narrows the pipe, until the drain blocks. Cleaning the trap regularly is far easier than clearing a blocked drain. Systems in rural buildings are often out of sight and out of mind.
We don’t list prices on the website, because the cost depends on the site in front of us. For a fixed quote, call us on 0345 646 2711, or send details by email, and we will explain what it covers.
