Lea Valley: your questions answered
Is Lea Valley within the area you cover?
Yes. Villages and rural sites across the South East are part of our work, Lea Valley included. Let us know about access, parking and anything unusual about getting there when you book.
Do you work overnight in Lea Valley?
Yes, we can come after you close and finish before you open. The work in Lea Valley can fit around your hours. Tell us your opening hours when you ask for a quote.
Which accreditations do you hold?
We are 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.
What do the grease readings need to be?
The TR19® Grease figures are a mean of 200 microns or less between cleans, and immediate spot cleaning wherever a reading hits 500 microns. Our report sets your readings against both.
Can you set up regular visits?
Yes. Tell us what you have and how it’s used, and we will suggest a schedule and quote for it.
What does a pre-clean survey involve?
A survey finds out how the system is laid out, how dirty it is and what can be reached, before anyone starts cleaning. Missing access panels are noted ahead of the clean.
What if parts of the system can’t be reached?
They’re listed in the report, never skipped quietly. You’ll know exactly which parts weren’t reached and why, along with a quote to put access in.
How long does grease testing take?
An inspection takes an hour or two for a single kitchen, longer for a large or complex system. Large or multiple systems take longer, so give us a ring on 0345 646 2711 or use the quote form and we will plan it.
About our TR19 inspection in Lea Valley
Post-clean verification is a check carried out once the cleaning is done, with new readings and photos of the cleaned areas. It shows whether the system was left in the condition the paperwork describes. If you’re dealing with parts of the system left out of past cleans and checking the result of a recent clean, we can put it right, from insurer audits, deposit thickness tests and pre-clean surveys onwards.
For a kitchen in or near Lea Valley, the visit is planned around opening hours and the journey, and the clean itself is the same full TR19® job as in any town: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
The report is your system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

What we do, step by step
Every visit runs to the same pattern: protect the area, make the system safe, do the work, clear away and hand over the paperwork. The visit itself takes around an hour or two per canopy and duct system. Rural roads and tight entrances are worth telling us about before a visit to Lea Valley.
- Post-clean verification is booked once the clean is done.
- The same access points are opened up.
- We repeat the WFTT or DTT readings.
- Photos are taken to show the condition after the clean.
- The results are reported, with anything missed flagged.
Getting ready for the visit
- Allow time for equipment near the work to be turned off and cool down
- Name a contact who can let us in at the agreed time
- Let us know about parking and loading

Quoting starts with a diagnosis, either from photos and details you send or from a site visit. Then we send a fixed price so you know the cost before any work starts.
Advice
What your team can do, and what needs us
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
Leave it or put it right?
If a kitchen in Lea Valley has been cleaned on the same calendar for years, there’s no way to know if that interval is right without measuring. Measured readings let a competent person set the interval. Equipment tucked in a roof space or outbuilding near Lea Valley rarely gets looked at unless someone books it.
You will not find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we will talk you through it.

Honest limits
A few issues sit outside what this work can do:

- Hidden runs that need access panels first
- Installation problems, which fall under design guidance such as DW172

Managing agents and facilities teams in Lea Valley
Whether it’s one building or many, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with photos.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
How the job changes from site to site
Restaurants, pubs and hotels
A kitchen running from breakfast to late service builds grease quickly. Readings show if the cleans are frequent enough.
Canopy and plenum
The plenum behind the filters can carry a lot of grease. Readings and pictures are taken in the plenum on every inspection.
Looking after it afterwards
How long the results last depends on use and care. We suggest:
- Flag changes in how much frying the kitchen does
- Report grease dripping from the canopy
- Clean grease off the canopy between professional cleans
- Keep the route to access panels clear
After post-clean verification, file the results with the cleaning certificate. Together they show the system was cleaned and checked.
Keep certificates, reports and readings in one place so the history is easy to show.
TR19 inspection around Lea Valley
The FSA’s food hygiene register includes about 13 pubs, bars and clubs within 1.5 miles or so of the middle of Lea Valley. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Hertfordshire Fire and Rescue Service covers Lea Valley. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. Kitchens in Lea Valley get their food hygiene inspections from St Albans City council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
If you run catering at a historic house or estate in the area (Shaw's Corner is about 2.5 miles north-east), event kitchens in older buildings often have awkward duct runs that need planning. If you run catering at a healthcare site, such as a hospital like St Albans City Hospital about 4.2 miles south, the extract may need cleaning more often than a part-time kitchen. Volunteers running a hall kitchen near All Saints, or anywhere in Lea Valley, may not know when the extract was last cleaned, and a grease test settles it.
