How to complain to BT
How to use BT’s official complaint process for billing, payment support, arrears or service issues.
BT publishes a formal complaints process and Customer Complaints Code. If your complaint concerns arrears, include the bill dates, balance, payments already made and details of any payment-support arrangement.
Make the issue specific
State whether the dispute concerns a missing payment, an arrears balance, a late charge, a payment plan or service restriction so BT can investigate the correct account history.
Keep the response
Keep BT’s complaint reference and final response because those records matter if the dispute later needs independent escalation.
