Police Architectural Liaison Officers

Police Architectural Liaison Officers (ALOs) are specifically trained in interpreting architects drawings and assessing the physical environment, in order to recommend measures that can be realistically applied to reduce or eliminate the risk of crime and anti-social behaviour, helping to create safe and sustainable communities.

How much does it cost?

All advice is provided free of charge.

What is it based on?

It is based on Crime Prevention Through Environmental Design(C.P.T.E.D.).

What can it be applied to?

It can be applied to proposed and existing developments.

What is it aimed at achieving?

It is aimed at designing out and removing opportunities for crime by alterations to the physical environment.

When is the best time to apply for the service?

It is most effective when applied at the design stage, thus reducing the risk of criminal activity and the associated on-costs to residents/occupants/landlords etc.

It can equally be applied to the existing environment but the initial outlay required for alterations may, of course, be greater than if the design had incorporated these measures from the start.

What kind of recommendations does it produce?

The C.P.T.E.D. advice provided includes recommendations for

  • Development or estate layout.
  • Maximising surveillance opportunities.
  • Appropriate siting of vehicular traffic and pedestrian routes.
  • Boundary or perimeter treatments.
  • Suitable access restrictions.
  • Effective lighting.
  • Appropriate physical and electronic security measures.

Will recommendations be sympathetic to design features?

It is important to remember that recommendations will be incorporated sympathetically to any development in order to reduce the outward signs of hardening; CPTED is empathetically applied to developments to ensure security and safety is incorporated without affecting aesthetics.

How can I benefit from Architectural Liaison services?

The official UK Police initiative, Secured by Design (SBD) is awarded to recognise adherence to this holistic approach to crime prevention, which blends physical security and police expertise together in order to reduce crime in the built environment.

The award is made to developers who adhere to the Police recommendations and has been proven to reduce housebreaking and criminal damage risk by at least 75%, further improving the safety and wellbeing of people places and communities.

The Safer Parking Scheme is a police initiative aimed at reducing crime and the fear of crime in parking facilities. ‘Park Mark’ is awarded to parking facilities that have met the requirements of a risk assessment conducted by trained Police officers. These requirements mean the parking operator has put in place measures that help to deter criminal activity and anti-social behaviour, preventing crime and reducing the fear of crime in their parking facility.

The ‘Park Mark’ scheme is managed by the British Parking Association (BPA) on behalf of Secured by Design.
