Changing the Door Locks on a New Home in London: Secure Your Property from Day One

Changing The Door Locks on a New Home in London: Why It’s a Critical First Step for Your Safety

Why You Should Always Change the Locks on a New House in London

The simple act of replacing your locks ensures that you have full control over who has access to your property, eliminating any risk posed by previous occupants, estate agents, contractors, or even neighbours who may have been entrusted with a key.

It’s not uncommon for multiple sets of keys to have been circulated during the selling or letting process.

Common Scenarios That Demand Immediate Lock Replacement

Previously rented property:
Tenants often duplicate keys without informing landlords. You can never be sure who still has access.

Lost keys before moving day:
If you’ve misplaced a key prior to settling in, there’s a possibility it may fall into the wrong hands.

Old or outdated locks:
Older locks are often easier to pick or break, and may not comply with modern British Standard BS3621 insurance requirements.

Why Lock Changes are Non-Negotiable in London’s Urban Landscape

Opportunistic crime is a serious concern, particularly in zones with higher rates of short-term rentals, student housing, or Houses in Multiple Occupation (HMOs).

By investing in a professional lock replacement right after you acquire the property, you are actively reducing the risk of:

Burglary and break-ins
Unauthorised entry
Compromised home insurance claims

Most insurers will not cover theft if there is no sign of forced entry and it’s discovered that someone accessed the home with a previously distributed key.

Which Locks Should Be Installed? Understanding British Standards

When replacing your locks, it’s vital to choose those that meet UK safety standards, especially if you want to stay compliant with your home insurance policy. Look out for:

✅ BS3621 Locks: Recognised by insurance companies, these are standard mortice or cylinder rim locks that offer a high level of security.

✅ Multi-point locking systems: These are commonly used on uPVC and composite doors and secure the door at multiple points with a single turn of the key.

✅ Anti-snap euro cylinders: These are essential for protecting against lock snapping — a common method used by burglars in London.
