The 5 Best Security Features for Your New Front Door
The 5 Best Security Features for Your New Front Door
When choosing a new front door, aesthetics and energy efficiency are important. But the non-negotiable, number-one priority is security. An unsecured door is just a “polite suggestion” to an intruder.
Butsecurity is a term that gets thrown around a lot. What really makes a door secure? It’s not just one feature, but a system of components working together. A great lock on a weak door is useless, and a strong door with a cheap lock is a vulnerability.
Here are the 5 key security features your new front door must have.
1. A Multi-Point Locking Mechanism
Gone are the days of a simple deadbolt and a latch. The modern standard for any high-security door is a multi-point locking mechanism. When you lift the handle and turn the key, you aren’t just engaging one bolt. You’re engaging a whole system of hooks, bolts, and compression cams that lock into the door frame at multiple points from top to bottom.
This does two things:
- It spreads any potential impact from a forced entry attempt across the entire frame, not just at one weak point.
- It creates a more robust, airtight seal, which also improves weatherproofing and insulation.
2. A 3-Star “Anti-Snap” Cylinder
This is arguably the most important single component. The lock cylinder is the part you put your key into. The most common break-in method in the UK is called “lock snapping,” where a burglar applies force to break a standard, cheap cylinder in half, giving them access to the lock’s mechanism.
The solution is a 3-star anti-snap euro cylinder. These are certified to the TS007 3-star standard. They are designed with a built-in weak point that snaps off if attacked, but leaves the core mechanism intact and secure, preventing entry. They are also protected against drilling and lock-picking.
3. A Solid Core Construction
A high-security lock system is only as good as the door it’s bolted to. If the door itself is weak, an intruder won’t bother with the lock—they’ll just kick the panel in.
This is where different door materials show their weaknesses:
- Basic uPVC Doors: Many standard uPVC doors have a multi-chambered plastic frame with a simple styrofoam-filled panel. This panel can be a major weak point.
- Traditional Timber: While strong, wood can warp, crack, or swell. This can create gaps that weaken the lock’s hold on the frame.
- Composite Doors: This is the clear winner. A modern composite door has a solid core, made of either laminated timber or high-density foam, encased in a super-tough GRP (Glass Reinforced Plastic) skin. This construction is incredibly robust and highly resistant to impact.
4. A Reinforced Frame with Hinge Bolts
Even if the door slab and lock are strong, what about the hinges? An old tactic is to attack the hinges and simply lift the door out of its frame.
A secure door system defeats this in two ways:
- Steel-Reinforced Frame: The uPVC outer frame should be reinforced with steel, preventing it from being bent or pried away from the brickwork.
- Hinge Bolts: These are fixed, high-tensile steel bolts on the hinge side of the door. When the door is closed, they slot into the frame, meaning even if an intruder grinds the hinges completely off, the door still cannot be removed.
5. Independent Security Accreditations
Finally, don’t just take a company’s word for it. Look for proof.
The two most important security accreditations to look for in the UK are:
- PAS 24:2016: This is the “enhanced security performance” standard. It means the entire door set (door, frame, locks, and hardware) has been rigorously tested to withstand a series of common attack methods.
- Secured by Design (SBD): This is the official police security initiative. SBD is an even higher standard that requires*PAS 24 certification. When you see the Secured by Design logo, it means the door is in the top tier of UK security.

Frequently Asked Questions (FAQs)
The most secure system combines a multi-point locking mechanism (with hooks, bolts, and cams) with a 3-star ‘anti-snap’ euro cylinder. One without the other is a vulnerability.
Lock snapping is a common burglary technique where intruders apply force to and break a standard euro cylinder lock, allowing them to access the internal mechanism. A 3-star anti-snap cylinder is specifically designed with a built-in weak point that snaps off, leaving the core mechanism intact and secure.
Yes. While both can have high-security locks, a composite door’s solid core (made of timber or high-density foam) is far stronger and more impact-resistant than a multi-chambered uPVC door. This makes the entire door unit, not just the lock, a powerful deterrent.
