Grease trap cleaning in London Colney
For kitchens across London Colney, grease trap cleaning fits easily around service. The trap is emptied, cleaned and checked, and the waste is taken away. It can be booked on its own or alongside other kitchen work. The work covers inline grease traps, restaurants and takeaways and school and care home kitchens, and people most often call us about an under-sink unit that needs regular emptying and a bad smell from the sinks or drains.
In a place like London Colney, kitchens often sit in older buildings with older drains. A blocked drain or a smelly grease trap is usually the first sign.
Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

When to call us in London Colney
Waste cooking oil poured down the sink fills a grease trap far faster than washing-up. Even small amounts add up.
If you notice any of these, it’s worth a diagnosis:
- A slow-draining kitchen sink
- Drains that gurgle and bubble
- A larger grease trap that needs emptying
- An overdue grease trap
School kitchens, at schools like Bowmansgreen Primary School for example, typically have their deep cleans and grease trap work done while the canteen is closed.

How it works
There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and photos. Most of the time goes on the work itself, which takes a short visit for a small trap and longer for an inline unit or interceptor. Getting to the system matters more than parking in a place like London Colney, so let us know how to reach it.
- We locate the trap and check how it’s fitted.
- We make sure nothing drains into the trap.
- We empty out the fat, oil, grease and solids.
- We clean every part of the inside.
- The trap is refitted, tested with water and the waste taken away.
How to prepare
- Let us know about parking and loading
- Let us know about permits to work or site inductions
- Allow time for equipment near the work to be turned off and cool down

Advice
How the job changes from site to site
Restaurant and takeaway kitchens
Busy kitchens with lots of washing-up fill traps fast. A shorter cleaning interval normally suits them.
Inline grease traps
Several sinks may drain into one inline trap. More waste means faster filling.
Leave it or put it right?
A smelly, overflowing trap attracts pests. Keeping the trap clean removes something they’re looking for as part of a clean kitchen. In a smaller place like London Colney, a site that has to close is felt quickly.

Honest limits
Not every problem is solved by grease trap cleaning, and we’d rather say so up front. It will not put right:
- A trap undersized for the amount of cooking
- Drains that need jetting rather than trap cleaning
- Collapsed or damaged drains, which need a drainage contractor
Not sure which it is? You can give us a ring on 0345 646 2711 or drop us a line and we’ll tell you honestly before you book.

What affects the quote in London Colney
Your quote is based on your site. We consider:
- Working hours and out-of-hours timing
- The size of the system
- The condition of the system
- How many systems or sites are involved
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You will have a fixed price before any work starts.
What to send for a quote
When you call or email, these details help:
- Close-ups of filters, grilles, hatches or access panels
- The roof, plant room or outside wall the system runs to
- The postcode and the type of business
- Your last certificate, test record or report
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, you get a fixed price before we start.
Looking after it afterwards
How long the results last depends on use and care. We suggest:
- Mention any increase in cooking
- Act on gurgling or smelly drains
- Scrape plates and pans into the bin before washing up
- Avoid pouring boiling water down to shift grease
Collect waste cooking oil separately rather than pouring it down the sink, and the trap will stay cleaner for longer. It’s the single easiest way to help.
More cooking means more grease in the trap. Booking cleans more often stops it overflowing.

Will you tell us when the next visit is due?
