All CEC iPads purchased via the framework supplier (XMA) come with a 2 year collect and return warranty.
If your iPad is no longer under warranty, or has sustained damage rather than developed a fault, you should arrange to have it repaired by a third-party company via Oracle.
We would advise against having older iPads which can no longer be updated to the most recent iOS repaired. Cracked screens cost around £80 to repair, so before arranging to have an iPad repaired, please consider the age of the iPad and whether purchasing a new iPad would be a better option.
It is important to note that any repairs made without using Apple replacement parts will invalidate your warranty.
