Complaint guides

Start with what went wrong—not the software.

Choose your situation for general guidance, questions to think about and examples of information that may help you explain your complaint.

Flight problems

Flight delay or cancellation

Organise your journey, delay information, expenses and airline response before preparing a UK flight complaint.

Vehicle purchases

Prepare a focused complaint about a vehicle bought from a dealer, including the advertised condition, faults, inspections and attempted repairs.

Home improvement

Organise the quotation, agreed scope, payments, workmanship evidence and attempts to put the work right.

Renting

Compare proposed deductions with the tenancy, check-in evidence, check-out evidence and deposit-scheme information.

Retail purchases

Record what you bought, what was promised, what went wrong and what the retailer has offered or refused.

Phone and broadband

Bring together outages, speeds, bills, promises and support calls before taking your phone or broadband complaint further.

Insurance

Compare the policy wording, claim evidence and insurer’s reasons before writing a formal complaint.

Property surveys

Prepare a measured complaint about a survey or valuation using the instructions, report limitations, visible evidence and resulting costs.
