UK cost sharing regulations have changed
Following extensive consultation, the CAA has introduced new mandatory requirements for all cost-sharing flights. Here's everything you need to know and how to stay compliant.
Implementation Timeline
Here's how the changes rolled out
2021-2022: Consultation Period
The CAA conducted extensive consultation with the aviation community on proposed changes to cost-sharing regulations.
Early 2025: Regulations Published
Updated Air Navigation Order published with final requirements and guidance documents (CAP 1590, CAP 1590A, and NCO.GEN.102).
October 1st, 2025: Mandatory Compliance
All cost-sharing flights must comply with new requirements. Non-compliance could result in regulatory action.
What's changed?
The new regulations introduce several mandatory requirements for all cost-sharing flights
Passenger Declaration Forms
Every passenger must complete and sign a declaration form before the flight, acknowledging the recreational nature and risks.
Must be retained for 6+ months
Enhanced Advertising Rules
All flight advertisements must include specific pilot credentials, license type, experience hours, and aircraft details.
7 mandatory disclosure requirements
Group Size Limits
Maximum of 6 people per flight (including pilot). Stricter enforcement of cost-sharing principles and equal contribution requirements.
No profit allowed - direct costs only
Platform Charter Requirements
CAA recommends using only platforms signed to the UK Cost Sharing Charter for added consumer protection.
Enhanced safety and compliance oversight
"These changes strengthen consumer protection while maintaining the flexibility for pilots to share flying costs responsibly. The new requirements ensure passengers are fully informed about the nature of recreational flights."

The practical implications for UK pilots sharing flight costs
More Paperwork

Better Protection
Enhanced consumer protection and clearer expectations for all parties involved in cost-sharing arrangements.
What are the key facts?
Essential requirements every UK pilot needs to know about cost-sharing flights
Direct Costs Only
Only flight-specific costs (fuel, landing fees, hire) can be shared. Aircraft ownership costs are not permitted.
Common Purpose
For A-to-B flights, pilot and passengers must share a common purpose beyond just cost-sharing.
Equal Cost Sharing
Costs must be shared equally among all participants, though the pilot can choose to pay more.
Maximum 6 People
Including the pilot, maximum 6 people per cost-sharing flight. No age restrictions apply.
Safety Disclosure
Passengers must understand this is recreational flying, not commercial public transport.
6-Month Storage
Passenger declarations must be retained for minimum 6 months after each flight.
