Kilobat broadband guide

# UK broadband complaints and minimum speeds

Contact your provider first and make a formal complaint if the issue remains unresolved.

## What to check

For participating providers, check the minimum guaranteed download speed and its conditions. An advertised average is different. Keep the complaint date, reference and plan wording.

## What to do next

Eligible customers can use the provider’s approved independent dispute resolution scheme after six weeks or earlier with a deadlock letter. Verify current eligibility and membership.
