9 May 2026Asking your landlord to take in a lodger or sub-let under the Renters' Rights Act: the tenant consent request walkthrough (RRA Day 9, May 2026)
A spare room earns nothing while it sits empty. A friend needs somewhere for three months. A second income would take pressure off a tight budget. Each of these is a reason a tenant might want to take in a lodger or arrange a short sub-let - and each requires, in most cases, the landlord's consent. The Renters' Rights Act 2025 has tightened the consent regime in some places (pets, most visibly) and left the lodger / sub-let rules broadly unchanged - but the escalation routes if a landlord behaves unreasonably are now significantly stronger. This walkthrough covers the two scenarios precisely, the clean consent-request letters (lodger and sub-let), what counts as reasonable refusal under the established framework, and the four-step escalation path to the Property Redress Scheme.
