Looking for TR19 inspection in City of London? We survey first, give you a fixed quote and work around your opening hours, finishing with a written report and pictures.

TR19 inspection for sites in City of London

Different parts, different methods

Extract fan and discharge

We look at where the extract discharges outside, since grease reaches the very end of the system.

Horizontal duct runs

If a run has no access panel, we note it so it can be fixed before the clean.

About our TR19 inspection in City of London

Before any clean in City of London, we survey the canopy, plenum, filters, ducts, fan and discharge. Access is checked along the full length, and record grease readings at set points. If you have heavy grease suspected in the plenum or ducts and post-clean verification after another contractor’s clean, we can put it right.

London kitchens are often tucked into basements or the back of a building, and the duct may run up through several floors before it discharges at the roof. In City of London, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.

Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

What TR19 inspection can’t fix

We won’t sell you work that does not address the problem, so these are the things it will not cover:

  • Ductwork that was designed or installed badly
  • Fire safety duties beyond the extract system
  • A faulty or failing extract fan

If you are not sure, just call 0345 646 2711, or send details by email and we’ll give you a straight answer.

What we work on in City of London

  • Wet film thickness tests
  • Insurer audits
  • Post-clean checks
  • Deposit thickness tests
  • Access surveys
  • Pre-clean surveys

What affects the cost of TR19 inspection

The diagnosis comes before the price. The main factors are:

  • The number of sites or systems
  • Whether we need access equipment or extra panels
  • The condition of the system
  • The times the site is available

We do not list prices on the website, because the cost depends on the site in front of us. For a fixed quote, call 0345 646 2711, or send details by email, and we’ll talk you through it.

What to send for a quote

The more you tell us, the more accurate the quote. When you get in touch, it helps to send:

  • Close-ups of filters, grilles, hatches or access panels
  • Where the plant sits or the system leaves the building, such as a roof or outside wall
  • Your opening hours and when the area is out of use
  • Any previous report or certificate

Quotes are quick. Send a few details and pictures, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

What TR19 inspection looks like in City of London

The FSA’s food hygiene register includes about 545 pubs and bars and about 129 hotels and B&Bs across City of London and its immediate surroundings (about a mile and a half). A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. The fire and rescue service for City of London is London Fire Brigade. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. In City of London, food businesses are inspected by environmental health officers from the City of London Corporation. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Our report lists what was cleaned and when, which is useful to have ready.

Where a hall near St Olave Old Jewry, or anywhere in City of London, hosts lunch clubs or events, its extract gathers grease just as a café’s does. If you run catering at a healthcare site, such as a hospital like London Bridge Hospital about 0.6 miles south-east, the extract may need cleaning more often than a part-time kitchen. School kitchens, at schools like Fashion Retail Academy for example, are typically cleaned in the holidays so no lunches are lost.

Why it’s worth doing now in City of London

After an incident, an insurer can ask to see proof of TR19 cleaning and inspection. Missing records can put a claim at risk. An up-to-date inspection report is a good place to start. It’s better booked as a planned job in City of London than handled as an emergency.

The price reflects the work, not guesswork. That’s why every job is surveyed first, and why the quote is fixed before work begins.

Staff cleaning versus specialist work

Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.

Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.

Landlords, agents and facilities managers

When the building owner and the occupier are different, the lease normally sets out who maintains what. We’re happy to deal with either side and send the paperwork to whoever needs it.

Whether it’s one building or many, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with photos.

How it works

Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. It takes a couple of hours for a typical kitchen extract system, and we clear up before we go. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in City of London.

  1. First we book a time that won’t disrupt cooking.
  2. The system is checked from canopy to discharge.
  3. Grease readings are taken at set points using WFTT or DTT.
  4. Photos are taken at each point, and access gaps noted.
  5. The findings go into a report with readings, photos and a recommended next clean.

Before we arrive

  • Let us know when the site is closed or quiet
  • Move anything stored near the system
  • Arrange a key holder or contact on site

Getting a quote

Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.

Your questions about TR19 inspection in City of London

Who enforces fire safety at workplaces in City of London?

That’s London Fire Brigade. TR19® isn’t law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.

Does London parking affect a job in City of London?

A loading bay, a visitor permit or off-street space near the site in City of London makes the visit easier to plan. If the building has a loading slot system, we’ll book into it.

How do you keep the site clean during the work?

With sheeting and covers, before anything else happens. We keep the work contained and clean down when we finish.

Can you price the work without visiting?

Yes, if we can see what we need. If not, a site survey comes first, and the quote follows that.

What do you do with what you remove?

It leaves the site with us when we go. While we work, it’s kept contained so the area stays clean.

Will you produce a report for our insurer?

Yes, anywhere in the area we cover. Tell us what your insurer has asked for and we’ll set the report out to match.

How often should grease be tested?

Enough to be sure grease stays within the TR19® Grease figures between cleans. If readings rise, the interval should shorten.

What do you need from me for a quote?

Only a few details: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. Then call us on 0345 646 2711 or drop us a line.
