There is no government web form for digital waste tracking
A common assumption at the yard is that come October there will be a government website where somebody types each load in. There will not be. Defra tested exactly that idea and dropped it. In its own words: "users reported that manually creating records on a GOV.UK style service was time-consuming and burdensome", so the service was built to receive records from software through an API instead.
The spreadsheet fallback
The only route without software is a spreadsheet upload. It is Defra's fixed template, around twenty mandatory fields per receipt, and you cannot change the format. Each spreadsheet is single use, so every submission means downloading a fresh file, filling it, and uploading it with a Government Gateway or GOV.UK One Login account. Defra describes it as "a temporary solution" it expects to keep "until at least October 2027" and will withdraw when appropriate.
The service also carries a charge of £26 a year for any legal entity that creates or edits records once reporting becomes mandatory, whichever route it uses.
What it means for a breaker
The two working day reporting deadline applies however you submit. A yard on the spreadsheet route is downloading, retyping and uploading against that clock for every load, with no vehicle lookup and no record kept for an inspector. Software fills the same fields from the reg at the gate. Whatever software a yard picks, the honest advice is the same: do not build a process on a route the government has already said it plans to switch off.
