Finding the meter behind the invoice
Serial numbers on paper and serial numbers on the wall should match. A walkthrough exists because they often do not.
An invoice is a claim that a particular meter recorded a quantity of fuel. The plant room is where that claim can be photographed. Between the two sit cupboards, landlord risers, and meters that were swapped during a weekend shutdown that nobody logged.
We ask to see the intake, not only the boiler. Heat meters on a district connection, check meters on a photovoltaic array, and a forgotten night-rate clock still in the old kitchen all change how a year should be drawn.
Photographs need the serial in focus and a second frame that shows the cupboard so a successor can find it in February. A close-up of digits alone is how packs become orphaned.
If access needs a landlord’s key, say so when you book the walkthrough. Waiting on the pavement with a camera is not a billed outcome we consider complete.
New automatic readers are useful when they exist and when someone still holds the export. They are not a substitute for knowing which room the old mechanical meter was removed from. That removal date belongs in the usage report if it falls inside the year.
