Libby (via local library) — borrow e‑books and audiobooks free

Libby is an app from OverDrive that lets UK library members borrow e‑books and audiobooks at no charge through participating public libraries; you’ll need a free library card from your local authority to sign in. Once linked, you can browse, borrow and stream or download titles for offline reading without any payment. The service is available to library cardholders across participating UK libraries and provides access to thousands of digital titles.
