This page is to supplment the BFI LFF 2025 Planner on https://lff-planner.co.uk and will explain the calculations we do for the end times of screenings.

We use different "buffer" times for different types of screenings and events in the BFI London Film Festival.

Buffer Times​

We use the following buffer times in our calculation.

These times are based on personal experiences and the valuable contribution of the BFI Southbank WhatsApp group.

Calculations​

The BFI London Film Festival provides the start time and the runtime of the film or duration of an event.

This results in the following calculation:

Start Time + Runtime + Buffer Time = End Time

I hope everyone finds the BFI LFF 2025 Planner website useful including CineSeats.

CineSeats is designed to give you as much detail as possible about specific cinemas and their individual screens—so you can book the seat that’s perfect for you.

Think of CineSeats as a cinema wiki. Information is organized by cinema chain, then by location, and finally by screen.

Most of the content comes from personal experience, supported by publicly available information. In the future, I’ll publish a dedicated post about sources and attribution. Longer term, the goal is to make CineSeats community-driven—where you can share your own insights and help improve the information for everyone.
