Merrow grease trap cleaning
Grease trap cleaning in Merrow from ventilation hygiene specialists trading since 2009. Out-of-hours visits and 24/7 emergency callout.
- A full, neglected grease trap
- A small trap that fills too quickly
- Grease setting in the kitchen pipework
How it works
The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. The work on site takes an hour or two in most kitchens, depending on the size and condition of the trap, and we clear up before we go. Because the survey comes first, a visit to Merrow can usually be finished without a second trip.
- First, we locate the grease trap and look at the pipework around it.
- We ask for the sinks that drain into the trap not to be used.
- We take out the layer of fat, oil and grease and any solids.
- We clean the chambers, baffles and connections.
- We put it back together, run water through and remove the waste.
Preparing for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Clear the space around the work
- Dig out any earlier paperwork for the system

How we handle grease trap cleaning in Merrow
Smells from the sink, gurgling drains or slow drainage all point to the grease trap. We find the trap, empty it and clean it, then check the water flows properly. If you are dealing with washing-up water that won’t drain away and an under-sink trap that keeps filling up, we can help.
Work in a smaller place like Merrow is planned around your opening hours.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Common problems we fix in Merrow
In Merrow, as everywhere, grease traps are easy to forget. Hidden under a sink or in a floor, it’s often ignored until something goes wrong.
If you notice any of these, it’s worth a diagnosis:
- A blocked kitchen drain caused by grease
- A routine grease trap service
- A slow-draining kitchen sink
- An under-sink trap that keeps filling up
If you run a church or community hall kitchen, near Church of St John the Evangelist or elsewhere in Merrow, a deep clean and an emptied grease trap before a busy season of events are worth booking.

Part by part
Grease interceptors
Interceptors separate grease the same way, on a larger scale. Cooling water lets grease rise and solids settle.
Baffles and outlets
Baffles inside the trap slow the water so grease can separate. They gather grease and debris so they’re cleaned every time.
Commercial kitchens in Merrow
The FSA’s food hygiene register shows about 16 cafés, restaurants and staff canteens and about 4 takeaways and sandwich shops in and around Merrow, up to about a mile and a half out. Kitchens like these wash fat, oil and grease down the sink every day, and a grease trap is what stops it reaching the sewer. Environmental health officers from Guildford council inspect food businesses in Merrow. They look at the cleanliness of the whole kitchen: walls, floors, ceilings and equipment. A record of each deep clean helps show the kitchen is kept in order.
For schools such as Bushy Hill Junior School, deep cleans and grease trap work are normally booked for the holidays. Healthcare kitchens cook through the year, so a deep clean has to be fitted around meals; St. Luke’s Hospital, about 1.5 miles south-west, is the nearest hospital to Merrow.

Merrow questions
Do you work in school kitchens around Merrow out of term?
Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 12 schools, colleges and universities with registered kitchens within about a mile and a half of Merrow. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Will you come out to Merrow?
Yes, we work in villages as well as towns, and Merrow is covered. Just mention lanes, gates or anything else about the site when you book.
Where does the waste go?
It’s contained and taken away. We collect grease, debris and waste water as we go, so it doesn’t spread.
What types of grease trap do you clean?
Under-sink and inline grease traps, and larger interceptors. They’re emptied, cleaned and checked whatever the size.
Are you fully insured?
Yes. We carry full insurance, and we’ve been trading since 2009.
How do you protect the area?
We cover floors and nearby surfaces with sheeting before we start, and anything we remove is contained. At the end, the area is cleaned down.
What’s TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
Can we book visits on a schedule?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. The report from each visit recommends the next date.
Aftercare tips
So the system stays in good health:
- Keep waste oil out of the drains
- Act on gurgling or smelly drains
- Keep access to the trap clear
- Wipe grease off pans before washing them
Once the trap is cleaned and refitted, the sinks can be used right away. Water is run through to check everything flows before we go.
Setting regular cleans takes the guesswork out. The interval is set to suit the trap and the kitchen.
Multi-site and managed buildings
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
