Grease trap cleaning in Blackfriars, done properly
A neglected grease trap stops doing its job. Fat sets in the pipes downstream, leading to slow drains, blockages and smells. Regular cleaning keeps it working. We’re often asked to deal with a kitchen drain that smells and a small trap that fills too quickly, across inline grease traps, under-sink grease traps and school and care home kitchens.
Across London, many commercial kitchens are compact and run long hours, so grease collects behind equipment, on ceilings and in drains and grease traps. In Blackfriars, deep cleans and grease trap work are usually done overnight.
We have 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.

Managing agents and facilities teams in Blackfriars
Multi-site operators often want one contractor and one number. We cover South East England and London, 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 send the paperwork to whoever needs it.
What we do, step by step
The first job on site is protection: floors, worktops and anything near the work are covered. Then we make the system safe and start. It takes an hour or two in most kitchens, depending on the size and condition of the trap, and the area is cleaned down before we leave. For a job in Blackfriars, tell us about loading bays, permits, lifts and roof access when you book.
- We locate the trap and check how it’s fitted.
- Sinks feeding the trap are taken out of use.
- 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.
Preparing for the visit
- Name a contact who can let us in at the agreed time
- Let us know about permits to work or site inductions
- Dig out any earlier paperwork for the system

Blackfriars questions
Does London parking affect a job in Blackfriars?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. If the building has a loading slot system, we will book into it.
Who carries out food hygiene inspections in Blackfriars?
Kitchens in Blackfriars are inspected by the City of London Corporation’s environmental health officers. An officer may look behind equipment and at drains, so it pays to have the deep clean booked before those areas build up.
Do you have insurance?
Yes. Duct Doctor is fully insured, and the details are available on request.
Do you provide a certificate or report?
Yes, always. It’s a dated, written report with pictures, and TR19® Grease cleans come with a certificate through the BESCA VHE portal. File it with your fire safety records.
How do you protect the area?
By covering it before any work starts. We keep the work contained and leave the area clean.
Do we need to stop using the sinks while you work?
The sinks that drain into the trap can’t be used while it’s open. We book the visit around your service so the kitchen isn’t held up.
What do you do with what you remove?
We take it away when we go. While we work, it’s kept contained so the area stays clean.
Do you clean under-sink and inline grease traps?
We cover under-sink, inline and interceptor units. Each one is emptied, cleaned and checked whatever the size.
What a clean won’t put right
We’d rather tell you now than book work that won’t help, so these are the things it won’t cover:
- Leaking pipework or sink wastes, which need a plumber
- Collapsed or damaged drains, which need a drainage contractor
- A trap undersized for the amount of cooking
Not sure which it is? You can phone us on 0345 646 2711, or email photos and we will tell you honestly.
Parts of the system we cover
- Restaurants and takeaways
- Pot wash sinks
- Inline grease traps
- Kitchen waste pipes
- School and care home kitchens
- Under-sink grease traps
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. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
You will not find a price list here, because the cost depends on the site in front of us. For a fixed quote, phone us on 0345 646 2711, or email photos, and we’ll explain what it covers.

Looking after it afterwards
How long the results last depends on use and care. Here’s what we suggest:
- Wipe grease off pans before washing them
- Tell us if your menu or hours change
- Keep strainers in every sink
- Keep access to the trap clear
We take the grease and solids away. Nothing is left for you to dispose of when we’re done.
A trap that is left too long stops catching grease. Regular emptying keeps it working and saves a call-out for a blocked drain.

In-house cleaning or a specialist?
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That is our job.
Blackfriars kitchens: local notes
Food Standards Agency records list about 4,454 cafés, restaurants and staff canteens and about 1,028 takeaways and sandwich shops within roughly a mile and a half of the centre of Blackfriars. Kitchens like these wash fat, oil and grease down the sink every day, and a grease trap is what stops it reaching the sewer. Kitchens in Blackfriars get their food hygiene inspections from the City of London Corporation. Walls, floors, ceilings and equipment are all part of what they look at. Photos and dates from each deep clean make a useful record. In London, deep cleans and grease trap work are typically done overnight, so the kitchen opens as normal the next day.
Hall and church kitchens, near St Ann Blackfriars or anywhere around Blackfriars, are used by many hands, and periodic deep cleans and grease trap visits keep them in order. School kitchens, at schools like Mercers' School for example, typically have their deep cleans and grease trap work done while the canteen is closed.

What we’re called out for in Blackfriars
In Blackfriars, as everywhere, grease traps are easy to forget. Hidden under a sink or in a floor, it’s often ignored until something goes wrong.
What we are most often called out for:
- An overdue grease trap
- Foul odours from the grease trap
- Drains that gurgle and bubble
- A larger grease trap that needs emptying
If you run catering at a healthcare site, such as a hospital like St Philip's Hospital about 0.6 miles west, deep cleans and grease trap visits are planned so meals still go out.
