Should landlords change the locks between tenants?

Changing the locks between tenancies is not a legal requirement, but it is a sensible and low-cost precaution.

Nationally, the proportion of rented homes is around 20%, with the concentration in London much higher and in some regions considerably lower. However, with 5.5 million homes in the private rental sector, post-tenancy security is a major issue. A locksmith Bishop Auckland or Bognor Regis is likely to be as much in demand as one in Birmingham or Bristol.

End of tenancy

When one tenant moves out, you cannot be sure all key copies have been surrendered. If a former tenant, their visitors or tradespeople still have access, you risk both the security of the property and the safety of your new occupant.

Routine maintenance

Even during a tenancy, a change of locks can be built into your maintenance programme. If keys were lost, the lock has become stiff, or there are signs of damage, it is advisable to replace the cylinder. Upgrading to BSI level, insurance-approved locks can strengthen security and appeal to prospective tenants. Always use one of the UK’s several thousand accredited locksmiths, such as //lockwork24-7.co.uk/locksmith/bishop-auckland/.

Legal obligations

Landlords must provide a safe, secure home and take reasonable steps to prevent unauthorised entry. Failing to act when you know unauthorised keys may exist could leave you liable after a break-in. Insurers may also question claims if you neglected to update locks where it was clearly advisable. For most landlords, the modest cost of changing locks is a worthwhile investment in risk reduction and tenant peace of mind.
