Proof your kitchen's compliant. Not just an invoice that says so.
You were told the extract needs certifying. Nobody told you what for, what it costs to get wrong, or what a proper job even looks like. We start with a free inspection and written workplan - so you never pay for compliance work you don't understand.
Does this sound familiar?
Told, not shown
Someone — landlord, insurer, fire officer — told you the extract needs certifying. They didn't tell you why, or what "properly done" actually looks like.
An invoice, not evidence
You've paid for a clean before. What came back was an invoice. Not what was measured, not what was found, not what changed.
Proof
Then there's a fire, a claim, an audit — and the "proof" sat in your files turns out to be a bill with a date on it.
THE STANDARD
What "properly done" actually means
A free inspection and written workplan first - so you know exactly what needs doing and why.
Grease deposits measured against the BESA TR19 standard — not eyeballed.
Before-and-after photos tied to your site, your ductwork, your job. Not a template.
A certificate that references the actual numbers taken on your system, signed by a TR19-certified technician.
One person accountable from first call to final sign-off. No passing between departments.
