About our TR19 inspection in North Street

TR19® Grease says grease should not exceed a mean of 200 microns between cleans, while a reading of 500 microns or more anywhere calls for immediate spot cleaning. Testing is how you know where your system stands. If you are dealing with missing access panels found on survey and missing TR19 certificates or history, we can put it right, from insurer audits, wet film thickness tests and access surveys onwards.

Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.

Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

North Street kitchens: local notes

About 51 miles out from central London, North Street is part of the South East area we work across. We work evenings, overnight and at weekends, so the visit fits around the site. Food hygiene inspections in North Street are the job of East Hampshire council’s environmental health team. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A dated certificate in the maintenance file answers the question before it’s asked.

Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Alton Community Hospital is the nearest hospital to North Street, about 5.1 miles north-east. Where a hall near Church of St Peter, or anywhere in North Street, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

North Street is about 6 miles south-west of Alton, in Hampshire. Whatever kind of site you run in North Street, we can take on TR19 inspection. Visits can be booked for evenings, overnight or weekends so the site keeps running. North Street is one of 683 places in Hampshire where we work for TR19 inspection. Our Southampton page covers sites nearby, about 18 miles away.

Why it’s worth doing now in North Street

A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. You’ll have a fixed price before work begins.

What we are called out for in North Street

Grease in a duct is flammable fuel. A flare-up on the range can be drawn into the canopy and duct, and from there a fire can spread through the ductwork. Knowing how much there is lets you act before it becomes a hazard.

Look out for these warning signs:

  • Kitchens whose menu or hours have changed
  • Pre-clean surveys before a first TR19 clean
  • An insurer’s request for a TR19 audit
  • Kitchens taken over with no cleaning records

Bursars and site managers at schools such as Ropley Church of England Primary School tend to book extract cleaning for when the kitchen is empty.

Comparing quotes

  • What records you’ll receive afterwards
  • Whether they’re fully insured
  • Whether a survey comes first
  • How they set the interval to the next visit

Choosing a duct cleaning contractor

Different parts, different methods

Restaurants, pubs and hotels

BESA’s minimum for heavy use of 12 to 16 hours a day is a clean every 3 months, and readings show whether that’s enough.

Extract fan and discharge

A greasy fan works harder and wears faster. The inspection shows whether it needs cleaning now.

Between visits

Good habits slow the build-up between visits. Our tips:

  • File every inspection report with your certificates
  • Look out for grease drips round the canopy edge
  • Send TR19 audit reports to your insurer on request
  • Diary the next grease test and clean

Readings of 500 microns or more are highlighted as needing immediate spot cleaning, and we can arrange it.

Revisit the cleaning interval whenever the menu or hours change. Fresh readings show whether it needs to change.

Managing agents and facilities teams in North Street

Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.

We also work for facilities teams across offices, schools and healthcare in North Street and across Hampshire. Work can be phased by floor, building or site around the people who use them.

How it works

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 morning or less for one kitchen, more where there are several systems. Seeing the system in photos first means the trip to North Street can be planned properly.

  1. We go through any past certificates and reports.
  2. We follow the extract from canopy to discharge.
  3. We note where access panels are and where more are needed.
  4. We measure the grease and photograph each point.
  5. We report back with readings and a fixed quote.

How to prepare

  • Name a contact who can let us in at the agreed time
  • Let us know how we reach the system, including roofs, risers and plant rooms
  • Tell us the best time to work, such as after service or at a weekend

Ask for a quote

Here’s what helps us quote: the address, the type of site and when it’s open, pictures of the system and any previous report or certificate. Then give us a ring on 0345 646 2711, or send details by email.

Advice

FAQs for North Street

Which fire authority looks after North Street?

Fire safety enforcement in North Street is handled by Hampshire and Isle of Wight Fire and Rescue Service. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.

Do you work overnight in North Street?

Yes, out-of-hours work is a big part of what we do. The work in North Street can fit around your hours. Tell us your opening hours when you ask for a quote.

What is grease thickness testing?

The Wet Film Thickness Test (WFTT) and Deposit Thickness Test (DTT) measure how thick the grease is at a given point. Readings are taken at set points through the system.

What does TR19 mean?

It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.

Do you work with multi-site operators?

Yes. Tell us the addresses and what each needs and we’ll quote them together.

Do you carry out TR19 audits for insurers?

Yes, for kitchens across the South East and London. Share the insurer’s request so the report addresses it.

How far ahead should we book?

Book as early as you can for planned work, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.

How often should grease be tested?

It depends on how heavily the kitchen cooks. BESA’s minimum cleaning intervals are every 3, 6 or 12 months for heavy, moderate and light use, and testing shows if your kitchen needs more.
