A growing patchwork of rules

Licensing depends on the council area as well as the property, and more councils are introducing schemes. Since the Renters' Rights Act, the penalties for getting it wrong are much higher, and the new PRS Database will make unlicensed lets easier for councils to find.

The three schemes landlords need to know

  1. Mandatory HMO licensing. Applies across England to properties let to five or more people forming two or more households who share facilities.
  2. Additional licensing. Councils can extend licensing to smaller HMOs, often three or four sharers, in designated areas.
  3. Selective licensing. Covers all privately rented homes in a designated area, whatever the number of tenants. New schemes continue to be consulted on across England.

Safety Certificates Every Let Needs

Every rented home needs a valid Energy Performance Certificate, and from 1 October 2030 must reach EPC C or have an exemption. Homes with gas appliances need an annual gas safety check by a Gas Safe registered engineer, electrical installations must be inspected at least every five years, and smoke and carbon monoxide alarms are required. Councils check these as part of any licence and can take action on their own.

Check before you exchange

Check licensing when you first look at a property, not after you buy. The council's website or a local landlord association will confirm what applies. Building the licence fee and any required works into your numbers early avoids a costly surprise. Some councils also use planning rules (Article 4 Directions) to restrict new HMOs.

Illustrative example · not a real client

Checking before, not after: a fictional case study

Ahmed was about to offer on a five-bedroom shared house in a London borough, assuming standard buy-to-let rules applied. His broker flagged that the house needed a mandatory HMO licence and that the borough ran additional licensing nearby. Ahmed built the licence fee and a fire-door upgrade into his offer, avoiding a costly surprise after completion.
