Hi,
The more savvy of you are probably already aware of this, but in case you are not, BT may extend the standard 12 month warranty for your Home Hub if you renew your annual broadband contract with them. The operative word is may, see this from their website:
http://bt.custhelp.com/app/answers/detail/a_id/646/c/In my case I have been a BT FTTC customer for over 2 years. During that time I have upgraded twice for free – firstly to the 80/20 service and very recently to include BT Sport. My BT contract has another 11 months or so to run.
Last week I took advantage of purchasing a HH4 at a much reduced offer price, and placement of the order generated an automated message from BT advising me that the HH3 warranty would expire on the date the HH4 was delivered.
On querying this with BT I was told that the H3 warranty would have continued to run for nearly 3 years (ie until the end of the current contract period connected with the recent BT Sport upgrade) if I had not ordered the HH4. Their policy appears to be that they only warrant one Home Hub per connection.
So the moral is, if your old HH expires don’t automatically assume that its warranty has expired.
