Frequently asked
Your questions, answered
Can I renew early without losing time?
Yes — since April 2018 you can have the check done up to two months before expiry and keep the original expiry date. There's no penalty for booking early, and it avoids the risk of a last-minute lapse.
What happens if my tenant won't give access?
Your legal duty remains, but you need to show reasonable attempts to gain access — written requests, dated records. Evening and Saturday appointments solve most access problems before they become a compliance issue.
