Just Moved? Why You Should Change Locks on a New House in London

Getting the keys to a new home or flat is an exciting milestone. Whether you’ve just bought a property in Acton (W3), rented a place in Shepherd’s Bush (W12), or moved your family into Harlesden (NW10), your to-do list is probably massive. You’re thinking about painting, moving boxes, and setting up the Wi-Fi.

But there is one critical security step that far too many people skip on day one: changing the locks.

While it might seem like an unnecessary expense right after paying estate agents and removal vans, taking the time to change locks on a new house in London is one of the biggest security gambles you can avoid."

1.  The Hidden Risk: Why You Must Change Locks on a New House in London

When the estate agent hands you that shiny new set of keys, it’s easy to feel like you’re the only person with access to your property. But think about the history of the building.

Before you took over, how many people had access to those exact same keys?

• Previous tenants or owners

• Estate agents and letting agents

• Cleaners and decorators

• Builders or maintenance contractors

• Neighbours holding spare keys

  
  

The truth is, you have absolutely no idea how many copies of your front or back door keys are floating around London.

This is why many homeowners arrange a Lock Change Service immediately after moving in.

Spending your first night in a new home knowing a stranger could technically walk right through the front door simply isn’t worth the risk.

2. The Insurance Trap: Why BS3621 Locks Matter

Here is something many London homeowners only discover after a break-in: if your locks do not meet insurance standards, your provider may refuse to pay out.

Timber Doors

A British Standard BS3621 mortice lock with the official Kitemark.

uPVC & Composite Doors

A properly functioning multi-point locking system with a secure cylinder — ideally an anti-snap or 3-star upgrade.

A professional Emergency Locksmith NW10 can quickly identify whether your locks meet modern insurance requirements.

If someone enters your property using an old key without signs of forced entry, insurance claims can become complicated very quickly.

3. Cheap Locks Can Put Your Home at Risk

Not all locks offer the same level of protection.

Many homes across West London still use old cylinders vulnerable to:

• Lock snapping

• Forced entry attacks

• Bumping

• Easy picking methods

  
  

Modern anti-snap cylinders are designed specifically to resist common burglary techniques used across London.

A trusted Anti-Snap Lock Upgrade can dramatically improve your home security in less than an hour.

4. Don’t Fall for the “£49 Locksmith” Trap

Many people moving into a new property search Google quickly and end up calling national call-centre locksmith companies without realising it.

These firms often advertise unrealistic prices like:

• “Lock change from £49”

• “Cheap emergency locksmith”

• “15 minute arrival guaranteed”

  
  

But once the subcontractor arrives, the final bill suddenly jumps into the hundreds.

Always choose a real local locksmith with transparent pricing, proper credentials, and genuine customer reviews.

A professional Locksmith Near Me should always explain prices clearly before starting work.

5. A Full Security Check Gives Proper Peace of Mind

Changing a cylinder is only part of the job.

When moving into a new property, a locksmith should also inspect:

• Patio doors

• Side gates

• Window locks

• Rear access doors

• uPVC handles

• Multi-point locking systems

  
  

Recently, AMZ Locksmith helped a family who had just moved into a property in NW10.

The previous owner had left multiple spare keys with contractors and neighbours during renovation work. We upgraded the front door to a high-security anti-snap cylinder and checked the rear door alignment during the same visit.

A proper Home Security Locksmith Service can help secure the entire property from day one.
