The trees have an electrical warranty of 1 year and during this time if one LED goes we will replace the whole branch. You’ll need to send it back to us and then we will send you out a replacement. Where trees are being assembled and dismantled multiple times warranty will be limited. You must retain your receipt as proof of purchase date. If you do not have your receipt, or after the warranty period has ended, you may send back the branch and we will repair or replace it for a small fee, dependent on the size of the branch. If you happen to lose a branch we can sell you a replacement branch at any time.
