Most retailers of consumer electronics sell extended warranties on their own products. This means that if you want to buy the warranty from their store you have to have bought the product from their site. Retailers such as Argos and Currys fall in to this category. 3rd party suppliers of extended warranties allow you to buy the product from any retailer and they will cover the product.
Different retailers impose different lengths of time between when you have to buy their cover. The Supply of Extended Warranties on Domestic Electrical Goods Order 2005 says an offer from a retailer of an extended warranty at point of sale needs to be valid for at least 30 days. This means that whatever price the retailer quotes you at the point of sale they have to by law allow you to buy the warranty at the same price for a minimum of 30 days. A lot of retailers allow you a longer period than the standard 30 days to buy the extended warranty.
If the retailer is not mention below you can assume they offer only 30 days.
Which retailers give you longer than 30 days to buy the extended warranty
- Argos offers 45 days
- Currys/PC World offers up to 1 year
3rd party extended warranty retailers
Some companies that do not usually sell the electrical products sell independent stand alone extended warranties which can be bought and will cover any product (check terms and conditions for exclusions).
