How often is a gas safety check needed?
The Health and Safety Executive says landlord-provided gas appliances and flues must receive a gas safety check every year. HSE guidance also describes a flexible window that can allow a check in the two months before the due date while retaining the existing annual cycle.
Use the expiry or due date shown on your record, and confirm the correct timing with your Gas Safe registered engineer. LetDue organises dates and evidence; it does not replace professional or legal advice.
