Grease trap cleaning for kitchens and businesses in St John's
Kitchens in St John's use us for grease trap cleaning, from small under-sink units to inline traps and interceptors. Visits are booked around your service, so the kitchen keeps running. If you are dealing with a full, neglected grease trap and an under-sink unit that needs regular emptying, we can help, from pot wash sinks, under-sink grease traps and inline grease traps onwards.
In a place like St John's, kitchens often sit in older buildings with older drains. Smells and slow drains are the usual warning signs.
The report is your system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Managing agents and facilities teams in St John's
We also work for facilities teams across offices, schools and healthcare across Surrey. Larger estates can be phased building by building to keep disruption down.
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
What we do, step by step
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes anything from under an hour to a few hours, depending on the trap. For a place like St John's, we load the van from the survey notes so the work can be done in one visit where possible.
- 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.
- We take out the layer of fat, oil and grease and any solids.
- Every part of the trap is scraped and cleaned, including the baffles.
- Once it’s refitted, water is run through to check it drains, and we take the waste with us.
How to prepare
- Mention any locked doors, roof access or ceiling voids
- Let us know about parking and loading
- Arrange a key holder or contact on site

Advice
How we price grease trap cleaning
Before we fix a price, we need to know a few things. We check:
- Access, including roofs, risers and ceiling voids
- When the work can happen, such as evenings, overnight or weekends
- How many systems or sites are involved
- Site rules, permits and inductions
What you pay reflects the actual work. That is why every job is surveyed first, and why the quote is fixed before any work starts.
What we need to know
To help us quote quickly, send us:
- The postcode and the type of business
- When the site is open and when it’s quiet
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Wide photos of the system and the area around it

Keeping the system healthy
After the visit, a few habits help the work last:
- Act on gurgling or smelly drains
- Fit sink strainers to catch food scraps
- Get food waste into the bin, not the sink
- Avoid pouring boiling water down to shift grease
We take the grease and solids away. Nothing is left for you to dispose of when we’re done.
A trap that’s left too long stops catching grease. Regular emptying keeps it working and saves a call-out for a blocked drain.
FAQs for St John's
Which council inspects kitchens in St John's?
Kitchens in St John's are inspected by Woking council’s environmental health officers. How often a business is inspected depends on the council’s risk rating for it, so the kitchen needs to be ready at any time.
Is St John's within the area you cover?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before work begins, and waste is contained as we go. Before we leave, we tidy up and clean down.
What’s the right interval for grease trap cleaning?
That depends on the trap and the kitchen. A small trap fills more quickly than a large one and the busier the kitchen, the faster it fills. We will suggest an interval after the first clean.
Does the report say when we need you again?
Yes. Every report includes a recommended date for the next visit, based on what we found and how the system is used.
Do you take the waste away?
The waste leaves with us. You’re not left with anything to dispose of when we go.
Can one contract cover all our sites?
Yes. Tell us the addresses and what each needs and we will quote them together.
Do you deal with blocked drains beyond the grease trap?
We clean the trap, not the drain network. Where the problem is further down the drain, we will say so so you can call a drainage contractor.
St John's kitchens: local notes
According to Food Standards Agency records, there are about 7 pubs, bars and clubs within roughly a mile and a half of the centre of St John's. Any of them serving food has a kitchen that collects grease out of sight and drains that need protecting. In St John's, food businesses are inspected by environmental health officers from Woking council. Grease behind equipment or on a ceiling is the kind of thing an inspection can note. Photos and dates from each deep clean make a useful record.
Brookwood Hospital, about 1 mile west, is the nearest hospital to St John's; healthcare kitchens cannot stop cooking, so deep cleans are worked around meal times. Where a church or community hall near St John's Church, or anywhere in St John's, has a kitchen used by volunteers, a periodic deep clean keeps it ready for the next event.

When it’s something else
Grease trap cleaning can’t fix everything, and we’d rather say so up front. It does not solve:
- Drains that are cracked or have collapsed
- A grease trap that’s too small for the kitchen
- Drains that need jetting rather than trap cleaning
If in doubt, phone us on 0345 646 2711 or use the quote form and we’ll say what we think before booking.
What we work on in St John's
- Restaurants and takeaways
- School and care home kitchens
- Inline grease traps
- Under-sink grease traps
- Kitchen waste pipes
- Pot wash sinks
What happens if it’s left?
A full grease trap lets grease through to the drains. There it sets and narrows the pipe until water can’t get through. Cleaning the trap regularly is far easier than clearing a blocked drain. Systems on quieter sites still build up dirt and wear, just more slowly.
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at, and you will get one fixed quote.
