FAQs for Colney Street
Can school kitchens in Colney Street be cleaned in the holidays?
Yes, holiday work suits schools best. There are about 5 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Colney Street. Booking early in the term gives the best choice of holiday dates.
Can you get to a site in Colney Street?
Yes. Colney Street is within the area we cover across London and the South East. A survey first, from pictures or a visit, means we arrive with the right kit.
Can one contract cover all our sites?
Yes. One number covers all your sites in our area, and visits can be set on a regular cycle.
How far ahead should we book?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and for anything urgent, ring our 24/7 emergency line.
What happens if you cannot reach some of it?
They’re listed in the report, never skipped quietly. You’ll know exactly which parts weren’t reached and why, and we can quote to improve the access.
Will I get paperwork for my records?
Yes. You get a written report with pictures after every visit, covering the work, any areas we couldn’t access and the recommended next date. Where the work is a TR19® Grease clean, there’s also a certificate issued through the BESCA Vent Hygiene Elite portal.
What accreditations do you have?
Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
How long will the sinks be out of use?
A typical clean takes an hour or so for an under-sink trap, longer for a larger unit, including testing. We plan the visit around your service.
Grease trap cleaning for kitchens and businesses in Colney Street
Fats, oils and grease are the main cause of blocked kitchen drains. Further on, grease can build into fatbergs in the sewer. A well-maintained trap keeps them out of the drains. Typical jobs include a regular cleaning plan for the grease trap and washing-up water that won’t drain away, across restaurants and takeaways, inline grease traps and school and care home kitchens.
Somewhere as small as Colney Street, the kitchens that need a deep clean are usually 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.
The paperwork matters as much as the work. Each visit is written up with pictures, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

When to call us in Colney Street
Every pan and plate washed sends grease towards the drain. They cool and float to the top of the trap and the grease layer grows.
Clients usually contact us after spotting something like this:
- A bad smell from the sinks or drains
- An inline trap or interceptor due for cleaning
- A grease trap that hasn’t been emptied in a long time
- Grease setting in the kitchen pipework
Healthcare kitchens, like those at hospitals such as Kingsley Green (about 1 mile east), cook for long hours, so deep cleans and grease trap work are planned around patients’ meals.
Before booking anyone
- When they can work, and whether that’s outside your opening hours
- If they look at the system before pricing
- Whether inaccessible sections are listed on the report
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
How the visit works
The visit has three parts: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and photos. The middle part takes longest, and that takes anything from under an hour to a few hours, depending on the trap. We agree a date with you, plan the drive to Colney Street and turn up when the site is quiet.
- First, we locate the grease trap and look at the pipework around it.
- Nothing drains into the trap while it’s open.
- The trap is emptied of grease and food waste.
- 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.
Preparing for the visit
- Mention any locked doors, roof access or ceiling voids
- Make sure someone can let us in and lock up afterwards
- Let us know when the site is closed or quiet
How to get a quote
To get a fixed quote, call us on 0345 646 2711 or email us with the site type, your trading hours and a short description of the system. A few pictures and your last certificate or report help a lot. We typically come back within one working day.
Advice
When it’s something else
Not every problem is solved by grease trap cleaning, and we’ll tell you before we start. It does not solve:
- A grease trap that is too small for the kitchen
- Collapsed or damaged drains, which need a drainage contractor
- Sewer problems outside the premises
If you are not sure, just call 0345 646 2711, or email photos and we’ll give you a straight answer before booking.
What the work covers
- Inline grease traps
- Restaurants and takeaways
- Pot wash sinks
- Kitchen waste pipes
- School and care home kitchens
- Under-sink grease traps
What happens if it’s left?
A blocked drain can stop a kitchen in its tracks. Water will not drain away, and dirty water can back up. Keeping the trap clean reduces the risk. If the system at a site near Colney Street fails, there may be nowhere nearby to move to.
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. You will have a fixed price before we start.

What grease trap cleaning looks like in Colney Street
Food Standards Agency records list about 17 restaurants, cafés and works canteens and about 7 takeaways and sandwich shops in and around Colney Street, 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. It’s St Albans City council that sends environmental health officers to food businesses in Colney Street. 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.
If you look after a school kitchen, at a school such as Park Street Church of England Voluntary Aided Primary School or anywhere near Colney Street, the holidays are the time for a deep clean or a grease trap clean. Hall kitchens near Church of the Holy Trinity or elsewhere in Colney Street may have older sinks and drains, so a grease trap check is worth adding to a deep clean.

Between visits
No system stays clean for ever, but care slows the build-up. Our tips:
- Keep waste oil out of the drains
- Act on gurgling or smelly drains
- Fit sink strainers to catch food scraps
- Keep access to the trap clear
The sinks are ready to use as soon as we have finished. Water is run through to check everything flows before we go.
A fixed cleaning interval means the trap never gets overfull. We agree the timing with you.
How the job changes from site to site
Under-sink grease traps
An under-sink trap is out of sight. A full one shows itself with a slow, smelly sink.
Baffles and outlets
Baffles inside the trap slow the water so grease can separate. Grease clings to them, so we clean them.

What else we do in Colney Street
In-house cleaning or a specialist?
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
