Understanding your door type is the first step to securing it properly. Different materials and constructions require specific hardware and locking systems. This guide breaks down the most common door types found in UK homes and the optimal security measures for each.
uPVC Doors
uPVC doors are the most common in modern UK housing. They typically feature multipoint locking systems that engage multiple bolts and hooks when the handle is lifted and key turned. To secure a uPVC door:
- Upgrade to an anti-snap, anti-bump, anti-pick cylinder (TS007 3-star rated)
- Ensure the multipoint mechanism engages smoothly — stiffness indicates wear
- Check hinge security bolts are fitted and engaged
- Consider a door chain or restrictor for additional control
Timber and Wooden Doors
Traditional wooden doors require different security approaches. The most effective setup combines:
- A British Standard 5-lever mortice deadlock (BS3621) positioned correctly
- A nightlatch for convenient everyday locking
- Hinge bolts to prevent the door from being lifted off
- A viewer or digital door viewer for identification before opening
Composite Doors
Composite doors combine the best attributes of multiple materials. They are incredibly strong and typically come with advanced multipoint locks fitted as standard. Security recommendations include:
- Verify the cylinder is at least 1-star rated, ideally 3-star
- Test the auto-locking feature if fitted
- Ensure the door frame is properly reinforced
- Consider smart lock integration for keyless convenience
Aluminium and French Doors
Aluminium doors, including French and patio styles, often feature slim frames that require specialist multipoint locks. Security tips:
- Install patio door locks or foot bolts for French doors
- Use anti-lift blocks on sliding patio doors
- Upgrade glass to laminated or toughened where possible
- Consider alarm contacts on sliding panels
Garage Doors
Garage doors are frequently overlooked but provide an entry point to your home. Upgrade to a garage door defender or install a purpose-made garage lock. If your garage connects to your house, treat the internal door with the same security as your front entrance.
