Why deal with it now?

If a kitchen in Alton has been cleaned on the same calendar for years, there’s no way to know if that interval is right without measuring. Testing gives you the evidence to set it properly. If an inspection, an insurer’s survey or a fire risk assessment is coming up in Alton, having the work done and recorded first helps.

One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. The price is fixed before work begins.

TR19 inspection for kitchens and businesses in Alton

Before any clean in Alton, we survey the canopy, plenum, filters, ducts, fan and discharge. We check where the access panels are and whether every section can be reached, and record grease readings at set points. We are often asked to deal with kitchens whose menu or hours have changed and sites with gaps in their extract records, on deposit thickness tests, pre-clean surveys and insurer audits.

Most kitchens in a town like Alton cannot close for a day, so cleans are booked after closing, early in the morning or on a quiet day. The kitchen is handed back clean and ready to cook.

A written report with pictures follows every visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Common questions in Alton

Who carries out food hygiene inspections in Alton?

In Alton, it’s East Hampshire council that carries out food hygiene inspections. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.

Who is the fire and rescue service for Alton?

Hampshire and Isle of Wight Fire and Rescue Service is the fire and rescue service for Alton. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.

What do you do with what you remove?

We contain it and take it with us. We collect grease, debris and waste water as we go, so it does not spread.

How long does a TR19 inspection take?

As a guide, it takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. The size of the system and the access make the difference.

What accreditations do you have?

CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We’ve been trading since 2009 and we are fully insured.

What does TR19 mean?

TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.

What if parts of the system cannot be reached?

They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, which we can install.

What do the grease readings need to be?

Between cleans, the mean should stay at 200 microns or below, with 500 microns or more anywhere needing immediate spot cleaning.

Keeping the system healthy

Looking after the system between visits is straightforward, and it helps at the next visit:

  • Never cook with filters missing
  • Clean grease off the canopy between professional cleans
  • Keep the route to access panels clear
  • Flag changes in how much frying the kitchen does

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

Keep all TR19 records together so you can produce them quickly.

What we do, step by step

When we arrive, we check the system against the survey or the pictures you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. Send us pictures of the system and we can plan most of a visit in Alton before we arrive.

  1. The visit is arranged for when the kitchen isn’t busy.
  2. The system is checked from canopy to discharge.
  3. Grease thickness is measured at set points by WFTT or DTT.
  4. We photograph the test points and record any sections we can’t reach.
  5. You get a report with readings, photos and recommendations.

Preparing for the visit

  • Clear loose items from the work area
  • Agree a time when the area can be out of use
  • Have your last certificate or report to hand

Advice

Common problems we fix in Alton

Looking at a canopy tells you little about what’s in the duct. Clean filters can hide a heavy layer behind them, which is why readings matter.

Most sites get in touch after spotting one of these:

  • Sites with gaps in their extract records
  • Post-clean verification after another contractor’s clean
  • Kitchens whose menu or hours have changed
  • Sections of duct that cannot be reached

Term dates shape school work: for a school like Saint Lawrence Church of England Primary School, an extract clean fits neatly into a half-term or summer break.

What your quote should include

  • Whether the quote shows VAT
  • Whether they recommend a next date
  • Which accreditations they hold, and whether you can check them
  • Whether the quote is based on a survey or pictures

Questions to ask before you book

For landlords and multi-site operators

When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.

We regularly work with managing agents. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.

Honest limits

TR19 inspection can’t fix everything, and we will tell you before we start. It doesn’t solve:

  • Ductwork that was designed or installed badly
  • Removing the grease, which is a separate clean
  • The responsible person’s own fire risk assessment

If in doubt, ring 0345 646 2711 or email us and we’ll say what we think before you book.

How the job changes from site to site

Canopy and plenum

Behind the filters, the plenum catches plenty of grease. Readings and pictures are taken in the plenum as part of every survey.

TR19 inspection in Alton: the local picture

The FSA’s data shows about 19 bars, pubs and nightclubs and about 3 hotels, B&Bs and guest houses registered within about 1.5 miles of central Alton. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Alton sits within the area of Hampshire and Isle of Wight Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. Environmental health officers from East Hampshire council inspect food businesses in Alton. Extraction counts as kitchen equipment, so its condition can come up on the day. Our report lists what was cleaned and when, which is useful to have ready.

A hall kitchen that only cooks for events, whether near Church of St Lawrence or elsewhere in Alton, still needs its extract cleaned, just less often. 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 Alton, about 0.9 miles south-west.
