Grease trap cleaning in Charlton, Hertfordshire
Need grease trap cleaning in Charlton? We diagnose first, fix the price and book the work around your hours, then sign off with a report and pictures.
- An inline trap or interceptor due for cleaning
- A grease trap that hasn’t been emptied in a long time
- A small trap that fills too quickly
How we handle grease trap cleaning in Charlton
No two traps are quite the same. Under-sink traps are compact and need frequent attention and larger traps hold more grease before they fill. We assess the trap and how fast it fills and suggest an interval that suits. The work covers restaurants and takeaways, under-sink grease traps and pot wash sinks, and people most often call us about an under-sink unit that needs regular emptying and a blocked kitchen drain caused by grease.
Somewhere as small as Charlton, 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.
For insurers and inspectors, the record counts. That’s why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Do you need grease trap cleaning in Charlton?
Hot water and detergent carry grease further than you’d expect. When it cools, the grease hardens in the pipework or the drain.
If you notice any of these, it’s worth a diagnosis:
- A blocked kitchen drain caused by grease
- Gurgling drains in the kitchen
- An inline trap or interceptor due for cleaning
- A slow-draining kitchen sink
School kitchens, at schools like Highbury Infant School and Nursery for example, normally have their deep cleans and grease trap work done while the canteen is closed.
Questions to ask before booking
- What insurance they carry
- What hours they’ll be on site
- Which accreditations they hold, and whether you can check them
- Whether a survey comes first
What affects the cost of grease trap cleaning
The price is fixed before any work begins. It takes into account:
- Working hours and out-of-hours timing
- The number of sites or systems
- Any permits to work or inductions
- Where the site is and how we reach it
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you’re not sure what’s needed, call us on 0345 646 2711, or send details by email for straight advice and a fixed quote.
What we need to know
To help us quote quickly, send us:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The paperwork from the last visit, if you have it
- The times we could work without disrupting the site
- Photos showing the whole system and its surroundings
Quoting starts with a diagnosis, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work, before work begins.
Commercial kitchens in Charlton
Food Standards Agency records include about 31 pubs, bars and clubs and about 4 hotels, B&Bs and guest houses within about 1.5 miles of central Charlton. Pub and hotel kitchens get the same build-up behind equipment and in the grease trap as any other. In Charlton, food businesses are inspected by environmental health officers from North Hertfordshire council. Grease behind equipment or on a ceiling is the kind of thing an inspection can note. Keeping a record of deep cleans and grease trap visits helps at inspection time.
Hall and church kitchens, near St Mary's Church or anywhere around Charlton, are used by many hands, and periodic deep cleans and grease trap visits keep them in order. Healthcare kitchens cook through the year, so a deep clean has to be fitted around meals; Lister Hospital, about 3.3 miles east, is the nearest hospital to Charlton.

What happens if it’s left?
A smelly, overflowing trap attracts pests. A clean trap is less of an attraction as part of a clean kitchen. Systems in rural buildings are often out of sight and out of mind.
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’ll have a fixed price before we start.

When it’s something else
Grease trap cleaning can’t fix everything, and we will tell you before any work starts. It does not solve:
- A trap undersized for the amount of cooking
- Broken pipework below ground
- Blockages further down the drainage network
Not sure which it is? You can ring 0345 646 2711 or use the quote form and we’ll tell you honestly before you book.
What the work covers
- School and care home kitchens
- Inline grease traps
- Kitchen waste pipes
- Under-sink grease traps
- Pot wash sinks
- Restaurants and takeaways
The process
Night work is normal for us. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes a short visit for a small trap and longer for an inline unit or interceptor. A few pictures of the system help us make the most of a visit to a place like Charlton.
- We find the trap and check how it’s connected.
- Nothing drains into the trap while it’s open.
- Built-up fat, oil and grease is removed from the trap.
- The inside, baffles and pipe connections are cleaned.
- We put it back together, run water through and remove the waste.
How to prepare
- Name a contact who can let us in at the agreed time
- Tell us where we can park and unload
- Tell us about site rules, permits or sign-in

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 photos, get a survey first. Either way, the quote is fixed before any work is booked.

Questions from Charlton
Do you clean school kitchens in Charlton in the summer holidays?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 12 schools, colleges and universities with registered kitchens within about a mile and a half of Charlton. Send us your term dates when you call 0345 646 2711 or email us, and we’ll fit the work in.
Can the work in Charlton be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Your opening times are the first thing we ask for.
What’s the right interval for grease trap cleaning?
It varies. We look at how full the trap is and how quickly it fills, then suggest a schedule.
Can you clear our blocked drains as well?
Our service covers the grease trap itself. Where the problem is further down the drain, we will say so so you can call a drainage contractor.
Do we need to close while you work?
Not usually. Visits are timed for when the area is closed, such as overnight or at a weekend, so the site can carry on as normal.
Are you fully insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Will you tell us when the next visit is due?
Yes. The report recommends when the next visit should be, based on what we found and how the system is used.
Aftercare tips
No system stays clean for ever, but care slows the build-up. Our tips:
- Never pour used oil down the sink
- Keep access to the trap clear
- Don’t rely on hot water to clear grease
- Tell us if your menu or hours change
You’ll get our view on how often the trap needs cleaning. That depends on how quickly it filled and how much the kitchen cooks.
More cooking means more grease in the trap. Booking cleans more often stops it overflowing.
Other services in Charlton
For landlords and multi-site operators
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We’re happy to deal with either side, and the report can go to both.
