Multi-point locks

A uPVC door will usually have a multi-point locking system. There are (at least) five points of contact from the door into the frame from top to bottom. This makes it harder to physically kick or ram the door open.

Everest doors have a robust three hook and two roller multi-point system. The door benefits from five points of contact and the hooks and rollers contact in both directions to deter forced entry.

However, the weakest part of a door is the lock and less secure cylinder locks have a vulnerability.

Secure locking

Most burglars get into the house through the door and 33% do this by forcing the lock. The cylinder or barrel that the key fits can be the weakest part of the locking and this can make the multi-point locking system redundant if the lock can be breached.

Euro-lock cylinders are vulnerable to an attack method known as ‘lock-snapping’. And intruder removes the casing around the lock to reveal the protruding cylinder and then used brute force to break the cylinder in half. A cylinder can be ‘snapped’ in as little as 5-10 seconds.

Lock-snapping became such an issue that a few years ago the police raised awareness with a national campaign. They worked with Secured by Design and the BSI to advise on minimum standards for anti-snap cylinders that could replace existing vulnerable cylinders.

A Euro-lock cylinder should be upgraded to a cylinder that meets the following standards:

  • BSI Kitemarked – TS007 3 Star Rating
  • Master Locksmiths Association - SS 312 3 Star Sold Secure Diamond

The lock cylinders used in Everest uPVC doors are designed so they can’t be picked, drilled or bumped and if snapped the added reinforcement of a cylinder guard prevents the removal of the cylinder keeping your door secure.

All Everest uPVC Doors are Secured by Design and the lock cylinders meet BS EN 1303:2015.

The average cost of items stolen from domestic burglary is £2,856 and the cost of damage is £846 (ONS).

Door handle and cylinder guard

For extra protection on a cylinder lock, a security door handle or a cylinder guard will also help to prevent lock-snapping attacks.

A security handle and cylinder guard both work in the same way to cover the protruding parts of the lock so a would-be intruder can’t get any tools to grip the edges of the lock.

The handle will also be extra strong to avoid the handle being snapped.

A door handle should be TS007 2 Star Approved or be part of a Secured By Design doorset.

Everest locks comprise of a set that incorporates a cylinder guard to prevent the removal of the cylinder, even if the lock has been 'snapped'.

Letterbox Cage Fishing Guard

What do many people do when they get home? Leave their door and car keys on a table in the hallway.

A popular method of burglary involves using a long retractable rod with a hook that can lift keys from a table through the letterbox.

A fishing guard letterbox has a cover at the back that stops a burglar from seeing into the hallway or from pushing the rod through the opening.

For a letterbox fishing guard, look for a security standard of TS008.

A doorset must be fitted with a letterbox fishing guard to earn the Secured by Design accreditation.

Door chain

A uPVC door security chain or bar is still a highly preventative security measure when opening a door to strangers. Especially for vulnerable people.

Make sure that the chain is tested and approved to TS003 standards.

Also, make sure that the chain is fitted correctly with the right screws that won’t come off under force.

A uPVC door will need the correct screws or rivets to make it secure.

As an alternative to a standard door chain, a door chain restrictor is screwed into the wall and then loops around the handle on a uPVC door.

In domestic burglaries, 76% of intruders break in through a door and 59% enter the house through the front (ONS).

Security or Sash jammers

If the lock on a door is forced open, a uPVC door security sash jammer adds another layer of security with a simple lever that pivots over the edge of a door. A door would usually have two security sash jammers fitted. One at the top and the bottom.

A non-locking sash jammer can be easily fitted on the inside of the door so it’s only manually operated from the inside. However, this can be an issue with elderly people if they fall and access is needed.

Key operated sash jammers are fitted through the frame of the door and can be key operated from the outside.

Note, Everest do not supply sash jammers.

Secured By Design accreditation

As of October 2015, all new build homes must be fitted with an entrance door that achieves PAS 24: 2016 to be Document Q compliant with Building Regulations.

When buying a new door always look for the PAS 24 standard, or Secured By Design.

Secured by Design (SBD) accredited uPVC doorsets meet requirements outlined by the police for crime prevention. To achieve SBD a door must meet the PAS 24: 2016 or similar standards:

  • STS 201 Issue 5:2013
  • LPS 1175 Issue 7:2010 security rating 2
  • STS 202 Issue 3:2011 burglary rating 2
  • LPS 2081 Issue 1:2015 rating B

    Are UPVC doors easy to break into?

    uPVC doors have multi-point locking that should make them very secure. However, multi-point locks are not effective if you don’t have a cylinder lock that meets standards.

    Some euro locks are vulnerable to lock-snapping and can be broken in 5-10 seconds by an intruder.

    Ensure that the complete door is Secured by Design or that the cylinder is TS007 3 Star Kitemarked or meets SS312 Sold Secure Diamond rating.

    You can fit a standard door chain to a uPVC door if you use the right security rated screws and rivets.

    The other option is to use a door chain restrictor that bolts into the wall at the side of the door frame and loops around the uPVC door handle.

    Can you put extra locks on uPVC doors?

    If your cylinder lock on a uPVC door is anti-snap and approved by Secured by Design or meets the ratings of SS312 Diamond or TS007 3 star then your door should be secure.

    It’s not usually possible to add another cylinder lock in the door as it wouldn’t be compatible with the multi-point locking system. By making changes to the door, it might invalidate any warranty or guarantee for the door.
