Letter of authority (let someone act for you) – free template (UK)

A letter of authority lets someone deal with a specific matter for you, for example collecting a parcel or talking to your bank, energy supplier or council. Organisations may still ask for ID or their own form. It is not a lasting power of attorney and does not work if you lose mental capacity.

Legal basis: General law of agency; for lasting decisions use a lasting power of attorney under the Mental Capacity Act 2005 · Legal position: October 2026

A letter of authority covers one task while you can still decide for yourself. To let someone make decisions for you in the long term, even if you lose mental capacity, you need a lasting power of attorney registered with the Office of the Public Guardian.
