TR19 inspection for sites in Belmont

TR19 inspection in Belmont

Taking on a kitchen in Belmont with no cleaning records? Start with an inspection. You get readings, photos and a clear view of what’s needed, before any cleaning is booked. The work covers access surveys, wet film thickness tests and post-clean checks, and people most often call us about cleaning intervals that may not suit the kitchen and an insurer’s request for a TR19 audit.

In London, few kitchens can spare a day to close, so work in Belmont is normally booked for the night or the early hours. Before the clean, we agree loading, parking and roof access with whoever manages the building.

We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

Signs you need TR19 inspection in Belmont

When a site in Belmont changes owner or cleaning contractor, the records do not always follow. Without them, nobody knows how much grease is in the system or when it was last cleaned.

It’s time to book a visit if you see:

  • Kitchen extract systems with no recent grease readings
  • Parts of the system left out of past cleans
  • An insurer’s request for a TR19 audit
  • Uncertainty over how often to clean

Term dates shape school work: for a school like St Joseph's Catholic Primary School, an extract clean fits neatly into a half-term or summer break.

Questions to ask before you book

Multi-site and managed buildings

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 to a regular schedule.

When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.

Staff cleaning versus specialist work

When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.

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’s where we come in.

Your questions about TR19 inspection in Belmont

Who carries out food hygiene inspections in Belmont?

In Belmont, it’s Harrow 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 enforces fire safety at workplaces in Belmont?

Belmont is in the area of London Fire Brigade. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.

What is post-clean verification?

After a clean, we take new readings and photos to show how the system was left. It can follow our own cleans or another contractor’s.

Why survey before a clean?

We check the layout, the grease levels and the access, before anyone starts cleaning. Any access problems are flagged ahead of the clean.

Will you produce a report for our insurer?

Yes. Many insurers ask for proof of TR19 cleaning and inspection, and an audit report gives you that, with recommendations where something needs doing.

How much notice should we give?

The more notice, the better, especially for out-of-hours work. Quotes usually come back within one working day, and there’s a 24/7 line for emergencies.

Is there a survey before the work?

Yes. For many sites, pictures and a few details are enough, and larger or hidden systems get a visit.

What grease levels does TR19 allow?

Two figures matter: a mean of no more than 200 microns between cleans, and 500 microns at any single point, which needs immediate spot cleaning. We show your readings against those figures.

When something else is needed

Some problems need a different service or another trade:

  • The legal duty, which stays with the responsible person
  • Installation problems, which fall under design guidance such as DW172
  • Mechanical faults in the extract

If you’re not sure, just phone us on 0345 646 2711 or email us and we’ll give you a straight answer.

Belmont kitchens: local notes

The Food Standards Agency lists about 22 pubs and bars as registered food businesses within roughly a mile and a half of the centre of Belmont. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Fire safety in Belmont falls to London Fire Brigade. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. Most London extract cleaning happens at night, after the last service.

Church and community hall kitchens, near Church of St Anselm or anywhere around Belmont, are easy to forget, but their extracts collect grease like any other. If you cook for passing trade around Harrow & Wealdstone station, the extract can be cleaned between your last and first customer.

Belmont is about 1 mile south-west of Stanmore, in Greater London. Belmont gets the same approach as every site we work on: diagnosis first, a fixed price, out-of-hours working where needed and a written report with pictures. Belmont is one of 764 towns, villages and districts in Greater London we cover for commercial clients. There’s also a page for London, about 12 miles away.

We cover every part of HA3 and HA7 for TR19 inspection and the streets around it. TR19 inspection is available to premises on The Avenue, Locket Road and Church Lane and the roads around them. If your site is just outside Belmont, we cover Harrow Weald (1 mile west), Stanmore (1 mile north-east), Headstone (2 miles west), Brockley Hill (2 miles north-east) and Hatch End (2 miles west). We also work in nearby towns such as London (12 miles south-east), City of Westminster (9 miles south-east), Marylebone (9 miles south-east), Kensington (9 miles south-east), St Pancras (10 miles south-east) and Shoreditch (12 miles south-east).

Around Belmont

In Belmont, that means kitchens and buildings near Whitchurch Junior School, Park High School and Canons Park, among other places. Belmont’s nearest station is Harrow & Wealdstone station, about 0.9 miles south-west of the centre. Other landmarks nearby include Hilfield Castle (3.7 miles north) and St. Anns (1.6 miles south-west). Not far away are Northala Fields and Stanmore Country Park.

How the job changes from site to site

Horizontal duct runs

Bends and long runs can hold heavy deposits, out of sight of the kitchen.

Vertical risers

Vertical risers take the extract up through the floors. Grease can drain down and pool at the bottom, so the base is a key test point.

How it works

The visit has three parts: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. The middle part takes longest, which takes an hour or two for a single kitchen, longer for a large or complex system. Security desks and permits-to-work are routine in London, so let us know what your building in Belmont needs from us.

  1. First we look at the system’s cleaning history, if there is one.
  2. We follow the extract from canopy to discharge.
  3. Access panels are located and any missing ones noted.
  4. We measure the grease and photograph each point.
  5. You get a report and a fixed quote for the clean.

Getting ready for the visit

  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
  • Clear loose items from the work area
  • Make sure someone can let us in and lock up afterwards

How to get 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.

What affects the cost of TR19 inspection

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • The size of the system
  • The condition we find in the survey
  • Site rules, permits and inductions
  • Working hours and out-of-hours timing

Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will explain each part.

Helping us quote

A few details help us quote accurately. With your enquiry, please include:

  • Any symptoms, from odd noises to smells or leaks
  • Your last certificate, test record or report
  • When the site is open and when it’s quiet
  • How we’d reach plant on a roof or in a plant room

There’s no standard price list, because every site is different. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To start, ring 0345 646 2711 or send us an email.
