Safeguard’s Insurance Approved LPC1 Security Grille

Safeguard Security’s LPC1 grilles are approved by the LPCB for insurance purposes and have successfully withstood a simulated attack under stringent test conditions.

As well as being an ISO 9001 accreditation body, the LPCB also tests security grilles in its own testing facilities. This test (LPS 1175) is intended for use in conjunction with the rules and regulations of the Association of British Insurers and Lloyd’s of London for insurance purposes.

In 2012 Safeguard Security launched its new Multi-Lock which has been approved by the LPCB to security level 1 (LPC1) issue 7. It is the only retractable grille approved to this latest issue level. This security grille has successfully undergone a simulated attack by an opportunist burglar using a variety of tools that can all be concealed about his person. This form of attack would represent virtually all domestic and commercial burglaries.

The attack is in two parts:

A soft body impact attack test

which is a laboratory method of simulating shoulder blows or kicking as a means of gaining forced entry.

A manual intervention test

which is a manual attempt at gaining forced entry with the aid of tools.

The attack tools used are as follows:

Non Tool

  • 1 Soft body impactor – 30kg

Prime Kit

  • 1 Screwdriver – 6.5mm/square x 150mm long
  • 1 Knife – blade 125mm long x 3mm thick
  • 1 Lever – 0.7kg/300mm long
  • 1 Glass cutter
  • 1 Cable Cutter – 150 mm long
  • 1 Scriber


  • Tweezers
  • Hooks
  • Pliers (including self gripping) – selection 200mm long
  • Spanners – selection 150mm long
  • Hexagon wrenches – selection 120mm long
  • Punches
  • Rope
  • Wire
  • Adhesive tape
  • Flexible plastic coupon
  • Wood/plastic wedges
  • Fishing line
  • Traction Screws
  • WD 40

Although designed to simulate an actual attack, the test is arguably much more severe than in reality because:

  • It is carried out by two experienced engineers
  • They have extensively studied drawings and the actual test sample prior to testing
  • The test is conducted in laboratory conditions:
    • Well lit
    • Dry
    • Warm
  • All the tools are to hand and can be used in combination
  • They can take it in turns to attack the security grille and have rests between attacks
  • The tester is allowed a one minute attack over a ten minute period for each chosen method and area of attack
  • In real life the burglar would be attacking through glass and the security grille would be installed behind a window or door frame
  • Finally, there is no need to be quiet and no fear of being discovered


Please note our LPC1 approved grilles can be recess or face fixed and are approved when installed in the following substrates – brick, concrete, block work, timber and steel. This assumes that the installation is direct to the substrate and not via intermediate substrates, such as plasterboard. However, the resistance to forced entry provided by the substrate itself is outside the scope of the approval.

As well as being an accredited ISO 9000 certification body, the LPCB also arrange testing of security products in their specialist security test facilities. These tests are intended for use in conjunction with the rules and regulations of the Association of British Insurers and Lloyd’s of London for insurance purposes.
