   - Replacement Options: Upgrading to more robust casement fasteners or stays is a viable option. Homeowners can replace these locks independently with basic tools.

3. UPVC Windows:
   - Common Locks: UPVC windows commonly use multi-point locking systems, which can include shootbolts, espag rods with rollers, or mushroom-headed bolts.
   - Replacement Options: Homeowners may consider upgrading to advanced multi-point locks for increased security. However, replacing these locks often requires professional assistance due to the complexity of the systems.

Conclusion:

While upgrading window locks for increased security is a wise decision, homeowners must consider the complexity of the locking systems, especially in modern UPVC windows. While some replacements can be done independently, intricate multi-point locks may require professional assistance. Homeowners should carefully weigh the security benefits against the potential challenges of sourcing and installing specialized replacement window locks.
