Being retired does not create a separate set of rights, but the Consumer Rights Act 2015 protects older consumers in the same way as other consumers. Goods should be as described, fit for purpose and of satisfactory quality; depending on the circumstances, you may be entitled to a repair, replacement, price reduction or refund. Services must usually be provided with reasonable care and skill, within a reasonable time and at a reasonable price where no price was agreed. Keep receipts and contact the seller first, then check GOV.UK or seek advice from a consumer advice service if the dispute is unresolved.
