You are confusing terms:
You have your statuatory legal rights which you can claim under for years after purchasing – this is what the seller has to work under. Distance selling regs, consumer rights act etc. These form a contract between you and the retailer / seller.
And you have a ‘warranty’ or ‘guarentee’ from the manufacturer which is additional to those and dealt with by the manufacturer. This is a contract between you and the manufacturer.
You don’t have a ‘statuatory warranty’ with the seller. Distance selling and CRAs are not a ‘warranty’.
And yes it is important that you are clear on what you are claimng under should you end up taking court action.
You can claim under statuatory legislation with the seller beyond one year but the burden of proof and the assumption of a fault being present at the time or purchase changes (after 6 months under CRAs).
Even if the manufacturer only gives a 1 year warranty, you can still claim against the seller under consumer law after this as it is 2 seperate contracts.
