Grease trap cleaning in Erith, done properly
Think of the grease trap as a filter for the kitchen’s drains. When it’s looked after, you hardly know it’s there but left too long, it causes trouble. Routine cleaning keeps it in good working order. If you’re dealing with a routine grease trap service and an overdue grease trap, we can put it right.
Every food business in London is inspected by its local council’s environmental health officers, and walls, floors, ceilings and equipment are all part of the picture. Kitchens in Erith often book a deep clean before or after an inspection.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

What happens on the day
There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. Most of the time goes on the work itself, and that takes a short visit for a small trap and longer for an inline unit or interceptor. A name and number for whoever controls access to the building in Erith saves time on the night.
- 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.
Preparing for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Dig out any earlier paperwork for the system
- Move anything stored near the system
Ask for a quote
Every quote begins with a look at the system, from your pictures and details or, where that isn’t enough, a survey on site. Then we send a fixed price, before we start.

Erith kitchens: local notes
The FSA’s data shows about 27 pubs, bars and clubs registered across Erith and its immediate surroundings (about a mile and a half). Any of them serving food has a kitchen that collects grease out of sight and drains that need protecting. Kitchens in Erith get their food hygiene inspections from Bexley council. They look at the cleanliness of the whole kitchen: walls, floors, ceilings and equipment. A cleaning log that includes deep cleans and grease trap visits shows the work is planned. Fat from London kitchens contributes to sewer blockages, which is why grease traps need emptying on a schedule.
For busy kitchens close to Erith station, deep cleans and grease trap work can be done after closing. School kitchens, at schools like Christ Church (Erith) CofE Primary School for example, typically have their deep cleans and grease trap work done while the canteen is closed.

What affects the quote in Erith
Every site gets its own quote. These are the things that affect it:
- The scale of the work
- One-off work versus a regular cycle
- The condition of the system
- Access, including roofs, risers and ceiling voids
We do not list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we will explain what it covers.
What to send for a quote
When you call or email, it’s useful to have:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- A few general shots of the system
- Your last certificate, test record or report
There’s no standard price list, because no two systems are the same. We look at your system first, from pictures or on a visit, and then send you a fixed quote. To get going, ring 0345 646 2711 or use the quote form.
What the work involves, part by part
Under-sink grease traps
Small grease traps sit under the sink. They fill quickly, so they need frequent emptying.
Restaurant and takeaway kitchens
Busy kitchens with lots of washing-up fill traps fast. They often need the most frequent cleaning.

Questions from Erith
Can you work in Erith outside opening hours?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Erith needn’t be disturbed. Let us know the hours you are closed and we will book within them.
Do you work in school kitchens around Erith out of term?
Yes, out-of-term visits are normal for schools. Around Erith, the Food Standards Agency lists about 22 schools and colleges with registered kitchens within a mile and a half or so. Send us your term dates when you call 0345 646 2711 or drop us a line, and we will fit the work in.
Do you work in Erith?
Yes. We cover Erith and the rest of Greater London, as part of our work across South East England and London. To book, phone us on 0345 646 2711, or send details by email.
Do you have insurance?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
Do you survey before quoting?
Yes. Photos often do the job, and larger or hidden systems get a visit.
What do you do to protect the area?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line for anything that can’t wait until a planned visit. Call us any time and explain what’s happened.
Will we have to shut during the visit?
Not normally. We work when the area is out of use, such as evenings, overnight, early mornings or weekends, so you keep your normal hours.
What happens if it’s left?
A full grease trap lets grease through to the drains. It hardens on the pipe walls until water can’t get through. Regular trap cleaning beats dealing with a blockage. Planning ahead in Erith lets you pick a quiet night rather than lose a busy one.
The cost depends on the size of the system, the condition it’s in and access to every part of it. You get a fixed price before any work starts, so you know where you stand.

Common problems we fix in Erith
Hot washing-up water keeps grease liquid for a while. Once it cools, it sets, often in the trap or the pipe beyond.
Common reasons sites call us are:
- Sinks that drain slowly
- Foul odours from the grease trap
- An inline trap or interceptor due for cleaning
- Gurgling from the sink waste
Healthcare kitchens, like those at hospitals such as Erith and District Hospital (about within half a mile south-west), cook for long hours, so deep cleans and grease trap work are planned around patients’ meals.
Before booking anyone
- What insurance they carry
- When they can work, and whether that is outside your opening hours
- What happens if part of the system cannot be accessed
- If the quote is a fixed price or an estimate
When it’s something else
Grease trap cleaning can’t fix everything, and we’d rather say so up front. It doesn’t solve:
- Grease deep in the drains, which needs jetting by a drainage contractor
- A trap undersized for the amount of cooking
- Blockages further down the drainage network
If in doubt, call 0345 646 2711, or send details by email and we’ll say what we think before booking.
Parts of the system we cover
- Restaurants and takeaways
- Kitchen waste pipes
- Pot wash sinks
- School and care home kitchens
- Inline grease traps
- Under-sink grease traps
