We cover poles except broken poles which are the result of accident or improper handling.
You can get insurance for your tent and we would suggest contacting The Caravan and Camping Club in the UK, if you are a UK resident.
If you have a broken part on your tent you must contact the dealer where you purchased the tent from. They will be able to obtain any replacement parts needed.
Alternatively,you can contact www.scottishmountaingear.com who might be able to help you source the replacement part.
