Grease trap cleaning for kitchens and businesses in Bishopsgate
A grease trap catches fats, oils and grease from the kitchen sinks before they reach the drain. Cooling water lets the grease rise and separate while the water carries on to the drain. Eventually it fills and has to be emptied and cleaned. If you’re dealing with a bad smell from the sinks or drains and a routine grease trap service, we can put it right.
London kitchens work hard in small spaces, so grease collects behind equipment, on ceilings and in drains and grease traps. In Bishopsgate, deep cleans and grease trap work are normally done overnight.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

What the work involves, part by part
Baffles and outlets
The baffles hold back grease while water flows on. Grease clings to them, so we clean them.
School, care home and staff kitchens
Drains in care settings need to keep flowing. Visits are planned between meals.

FAQs for Bishopsgate
What do you need to know about parking in Bishopsgate?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Much of our London work is done overnight, which helps.
Can you work in school kitchens in Bishopsgate during the holidays?
Yes, holiday work suits schools best. There are about 96 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Bishopsgate. Send us your term dates when you call 0345 646 2711 or send us an email, and we will fit the work in.
How much notice should we give?
For planned work, earlier is better, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
Do the sinks have to be out of use during the clean?
Only briefly, and only the sinks that feed the trap. We plan the visit for a quieter time where we can.
Do you provide a certificate or report?
Yes. Every visit ends with a written report and photos, 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.
How much does grease trap cleaning cost?
It depends on the type and size of the trap, its condition and access. Tell us about the trap and we will come back with a fixed price.
What accreditations do you have?
We hold 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.
What happens to the waste?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. We do not leave it behind.
When to call us in Bishopsgate
Food waste slips past sink strainers or gets rinsed down. It settles in the trap as solids and fill it from below.
Most sites get in touch after spotting something like this:
- An under-sink trap that keeps filling up
- An overdue grease trap
- Scheduled grease trap emptying
- Drains clogged with fat
For schools such as The London School of Barbering, deep cleans and grease trap work are normally booked for the holidays.
Before booking anyone
- Whether they recommend a next date
- Whether they’re fully insured
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether inaccessible sections are listed on the report
Why act early in Bishopsgate
Pests are drawn to grease and food waste. A clean trap is less of an attraction as part of a clean kitchen. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote and give you a fixed price before we start.
Why choose Duct Doctor in Bishopsgate
- Fixed quotes, normally within one working day
- A written report with photos after each visit
- Evenings, overnight and weekends, plus 24/7 emergency callout

Managing agents and facilities teams in Bishopsgate
We regularly work with managing agents. Send the address, what’s needed and how access works, and we’ll send a fixed quote.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
What we do, step by step
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. Most London sites can’t stop for the day, so work in Bishopsgate is typically done overnight, early in the morning or at weekends.
- 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.
- The chambers and baffles are cleaned.
- We refit it, run water through and remove the waste.
Before we arrive
- Name a contact who can let us in at the agreed time
- Mention any locked doors, roof access or ceiling voids
- Have your last certificate or report to hand

Bishopsgate kitchens: local notes
The FSA’s food hygiene register shows about 55 food manufacturers and packers in and around Bishopsgate, up to about a mile and a half out. For food producers, the grease trap schedule should follow the volume going through it. It’s Tower Hamlets council that sends environmental health officers to food businesses in Bishopsgate. 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. Most London kitchens cannot close in the day, so deep cleaning is usually done overnight.
Where a church or community hall near Church of St Ethelburga, or anywhere in Bishopsgate, has a kitchen used by volunteers, a periodic deep clean keeps it ready for the next event. For a café close to London Liverpool Street station, a deep clean can be done between closing and the morning rush.

In-house cleaning or a specialist?
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
Keeping the system healthy
Results last longer with the right care. Here’s what we suggest:
- Keep waste oil out of the drains
- Avoid pouring boiling water down to shift grease
- Keep access to the trap clear
- Book trap cleans at a set interval
The waste we remove leaves with us. There’s no greasy waste left on site when we’re done.
More cooking means more grease in the trap. Booking cleans more often keeps the drains flowing.
