Theft, vandalism and arson are the crimes most likely to affect your business. Appropriate security measures can help reduce the risks and the potential impact on your business.

There is no single solution. You need to identify the particular threats you face to decide which are the right security measures to make your premises safer.

1. Assessing the security risk

Apart from the financial costs, crime can disrupt your business. Assess the risks your company faces and put protective measures in place. This will save time and money later.

Find the weak points in your security

  • Is there a controlled access system in place? If not, is it practical to introduce one?
  • What are the possible entry points? How easy would it be to break in at each of these points?
  • If a thief gained access to the premises, what is most likely to be stolen? How secure are those items?
  • How easy would it be for a thief to get away with stolen items? How long would it be before the alarm was raised and somebody arrived on the premises?
  • How easy is it for somebody to start a fire?

Find out what kinds of crime are taking place in your area

  • Speak to police and to neighbouring businesses. For example, smashed windows or graffiti may be a problem in some areas.
  • Meet your permanent beat officer - or the liaison officers for self-help schemes, like your local office watch, pub watch or club watch. Ask them about other businesses or organisations in the area which could affect your security.

2. Basic premises security precautions

Overall responsibility for security should be allocated to one individual

Even if you contract out some additional security requirements, the overall responsibility remains yours. One individual should:

  • check the premises and security systems regularly and review when appropriate
  • check that security procedures are being followed
  • maintain contact with police, insurers and fire services

Reduce the risk of thieves gaining access to your premises during business hours

  • Shoplifters and thieves often assess how easy it is to steal from premises by how quickly they are greeted by a member of staff. Position a staff member, such as your receptionist, near the door to keep track of who comes in and out; or install an entry phone
  • Make sure visitors identify themselves and state who they are visiting. Consider issuing passes or signing visitors in and out.
  • If possible, keep all other external doors locked. But check fire regulations first.

Ensure all employees understand and comply with security and safety procedures

  • Encourage your employees to challenge visitors (Can I help you?) if they do not recognise them.
  • Make sure safety information, such as fire drill details, is prominently displayed in your premises.
  • Keep a record of key holders, and stress the importance of keeping keys secure.
  • Change alarm codes on a regular basis and whenever an employee leaves.

Work with the local police

  • Arrange to meet your local crime prevention officer and seek advice on security measures.
  • If appropriate, establish key contacts with the police. If you are particularly at risk, officers may check your premises regularly during the night.
  • Ask your local police station, crime prevention or community support department to add your details to their email or text messaging list to receive local community news and broadcasts relevant to your business.

3. Physical premises security

Insurance companies may insist on minimum security standards for locks, windows, and the perimeter and roof of your premises. Strengthen potential entry points.

Ensure your locks are effective

  • They should conform to British Standard 3621.
  • Consider locks with registered keys, for which extra keys are only available with written confirmation from the owner.
  • Label keys with a code that you can explain to employees, but which outsiders will not understand.

Make sure all windows are shut and locked when the premises are unoccupied

  • Repair or replace any faulty windows immediately.
  • Install window locks on ground floor windows.
  • Consider installing rolling shutters or laminated glass.

Window bars or grilles are an effective deterrent, especially when fitted internally

  • If possible, protect all accessible windows.
  • Consider solid steel bars set in concrete in the wall.
  • Collapsible gates are also recommended, and can look better.

Protect the perimeter of your premises

  • Put up a wall or fence.
  • Illuminate all potential entry points to the premises. But bear in mind that, in isolated areas, lighting could assist a thief in gaining entry to the building.
  • Secure car park gates with a strong chain and padlock when not in use.
  • Consider installing ant-ram bollards.
  • Consider using barbed wire, anti-climb paint or other anti-climb security measures on outside walls over eight feet high. This will discourage vandals and criminals, but it should be a last resort. Someone could injure themselves and claim damages from you (for example, children playing).
  • Store wheelie bins securely away so that they can't be used to gain access to the building.
  • Do not make your premises seem like a fortress. It may deter customers and potential employees.

Store high-risk items securely

  • Used cooking oil is a popular target for thieves as it can be used to make biodiesel. Businesses with stores of used oil such as restaurants and takeaways should use lockable storage containers and authorised waste disposal services.
  • Keep tools, company vehicles and materials securely locked away.

Secure empty premises

  • Empty buildings are a target for squatters, graffiti artists, vandals and thieves. Consider deterring them by installing live-in 'guardians' or a regular security patrol.

4. Electronic security

Electronic security provides another level of protection for your business. Intruder alarms and CCTV 
can be powerful deterrents. Discuss with your insurers what measures you should consider.

Look at a wide range of alarms before making a decision

  • Compare specifications and quotes from a number of suppliers.
  • Consider buying an alarm system, rather than leasing one. If you lease an alarm, you are committed to using the same firm to maintain it.
  • For reliability, your alarm should comply with British Standards BS EN 50131. Make sure the supplier is approved by the National Security Inspectorate (NSI).
  • Check that your insurer will accept an alarm installed by your chosen supplier.
  • Appoint a key holder to check your premises if the alarm goes off. The key holder must be able to get to the premises within 20 minutes.
  • Consider installing panic buttons as part of your alarm system.

In commercial premises, audible-only alarms have limited benefit

  • Consider an instant response service by connecting to an Alarm Receiving Centre (ARC).
  • When the alarm is activated, the police are sent to your premises. A key holder from your business must then let them in.
  • Smoke-generating devices can create a smokescreen if someone gains unauthorised entry, making burglary more difficult.

False alarms can be a problem

  • Police forces generally have a policy of refusing to respond if you have a history of false alarms.
  • The cause of false alarms can be faulty equipment, but it is usually human error.
  • Consider a system that includes alarm confirmation technology to minimise false alarms.
  • Test your burglar and fire alarms regularly.
  • Make sure regular maintenance is carried out by a competent NSI-approved alarm company.

Consider installing CCTV

  • CCTV is widely used as a deterrent and can also discourage employee theft.
  • It allows one person to monitor multiple areas, including remote sites. This is especially useful for security guards.
  • CCTV can be cost-effective for monitoring remote sites. It can be used to call a Security Guarding Company or the police for instant response with visual and audio verification from a remote manned centre.
  • If CCTV is not monitored, it is only useful after the event.
  • Your employees may not like the idea of being watched. Explain why you are introducing CCTV and clear up any objections before it is installed.
  • To comply with data protection regulations, you must ensure CCTV does not unduly impact on privacy and that suitable signage is installed.

5. Preventing IT theft

IT theft often has serious consequences for businesses. The loss of computers can be extremely costly and disruptive.

There are many ways to secure your physical IT assets

  • Site your IT equipment away from the most visible and accessible places. Consider putting key equipment, such as your network server, in a locked room or a security cage.
  • Mark your equipment in a permanent and visible way.
  • Use steel cables to anchor your equipment to furniture or the floor. Use special security screws that will prevent any intruder gaining quick access to the components inside your computers.
  • Fit computer alarms that detect tampering.
  • Theft of laptops and smartphones is common, so lock them away when not in use. Install software that will allow you to 'wipe data' remotely.

Secure the data on your computers

  • Back up files regularly. Check that your back-up system is working properly, by 
re-installing and checking files. Keep copies of back-ups off-site.
  • Use passwords or biometric data to prevent unauthorised access to computer files.
  • Use anti-virus software.
  • Set up procedures to screen all incoming material - and insist they are used.
  • Certification to the government-backed Cyber Essentials scheme can be a useful starting point.

6. The threat of arson

Do not allow combustible material to accumulate in or near your premises

  • Arsonists could use it to attack the building.

Lock away hazardous and flammable materials

  • Control access to vulnerable areas, such as warehouses.
  • Store wheelie bins, skips and stores of waste oil securely, away from the building.

Make sure you have the necessary fire precautions in place

  • Fit fire alarms and smoke detectors to detect fires early. They should conform to British Standard BS 5839.
  • Ensure there are enough fire extinguishers, of the right types and in the right places.
  • You have a legal responsibility to carry out fire risk assessments and ensure you have appropriate fire precautions in place.

7. Additional security

If your business faces particular risks, you may need to consider additional security measures.

Employ a security company

The services a good company can offer usually include:

  • auditing current security arrangements and suggesting improvements
  • specifying and fitting any new security systems required
  • providing periodic (eg twice per night) or full-time inspection of your premises outside business hours

A security company can provide a security guard to protect your premises

  • Make sure the guard comes from a firm registered with the British Security Industry Association or the International Professional Security Association. Or look for a Security Industry Authority (SIA) Approved Contractor.
  • Make sure the security guard holds an SIA licence. It is illegal not to hold one - without it, insurance claims could be invalid.
  • The security company should screen and interview each guard as thoroughly as you would check a new employee.
  • Discuss the security orders for the guard, including hours, duties and equipment with the supervisor responsible for your site.

Integration of security is the key to success

  • For example, using CCTV and guards together will provide maximum protection.

8. Mitigating any loss

Review your security systems regularly.

Anticipate possible losses

  • Maintain a detailed inventory of your assets. Send a copy to your insurer.
  • Devise a disaster recovery plan to cover the whole range of possible situations.
  • Take pictures of your assets and store them off-site or in the cloud.

Act quickly after the event

  • Involve the police and your insurance company immediately.
  • Secure any broken points of entry.
  • Review and upgrade your security systems.

You are most at risk immediately after a break-in or a theft

  • The criminals know the layout of the premises and that you will quickly replace the stolen items.

Your insurance

Improved security can save you money on insurance

  • Tell your insurance company what measures you propose and discuss how this may affect your premium.
  • Your insurers should be able to help with technical security specifications.

Keep your insurers informed about any material changes to your security

  • Get your insurance company's approval for proposed security measures before buying or installing new protective measures, including new equipment.
  • Most problems with insurers result from not keeping them up to date with changes to your business.
