Securing Guarding Tenders

Most businesses, both public and private, look to outsource their security requirements to a third party specialist. As a result, there's lots of contracts and tenders available for security businesses to generate partnerships.

Bidding for security tenders is a great way to grow or diversify your business, opening up lucrative contract opportunities. 

However, this can come with its own challenges as finding, developing and winning tenders can be daunting, suck up important resource, and not always be successfully rewarding with a lack of knowledge and experience in bid writing. This is where we can help!

How can I win a security tender?

With a broad range of services comes a high volume of opportunities within the security industry. This also presents a lot of competition, making tendering for security contracts quite challenging. 

That's why it is important to evidence and thoroughly explain the solution your business can provide. In our experience, we have generally found the following helps to win a security tender:

  1. You should show how robust your recruitment and vetting procedures are. Including an aspect of social value in here (as discussed below) would also be worthwhile. 
  2. Effective monitoring and supervision of operatives should also be considered. This should be in-line with how you measure and report on performance overall and how your team play a critical role in this. 
  3. Social value is increasingly important across all public sector tenders, including security tenders. Therefore you should demonstrate the positive impact you could have both on the contract and in the wider community longer-term. This should also show you that services can have a positive effect on driving efficiencies and cost savings. 
  4. With the increasing and evolving risks to businesses and properties across the UK, many buyers will be looking for innovation, particularly in how you can respond to issues timely and professionally, mitigating and planning for any scenario. 
  5. Continuous training can help support with the point above and should be discussed to evidence the skills and accreditations your business and team have to be equipped and confident in their approach to respond to security challenges.

Security guarding, manned guarding, marshals, key holding, mobile security, event security and stewarding all largely come under security services tenders especially when being advertised by the Public Sector. These buyers or Contracting Authorities will use CPV codes or common procurement vocabulary to help security guard bidders find the relevant tenders. These include:

  • Security services (79710000-4)
  • Guard services (79713000-5)
  • Patrol services (79715000-9)

By using our free software Tender Pipeline, you can set up email alerts, search by keywords or CPV and monitor your security services competitors.

Public Sector buyers, such as Housing Associations, Universities, Colleges, NHS and Councils will often use existing framework agreements so it is important as a security guarding contractor that you monitor these. For example:

Southern Universities Purchasing Consortium - Manned Guarding and Associated Services

Crescent Purchasing Consortium – Security Services Framework

LHC – Property Safety & Security Framework

NHS North of England Commercial Procurement Collaborative – Security Services for the Healthcare Sector

Or within wider Estate Management or Facilities Management Frameworks with the likes of Crown Commercial Services (CCS).

Buying will be looking for a security guarding organisation who have their security accreditations, relevant case studies, is financial security with appropriate levels of insurance. In addition to these more basic requirements, they will want to understand your expertise, management team, service levels, how you would reduce risk and implement the contract quickly and often with TUPE implications. You would need to demonstrate you hold similar values, for example, by making Social Value commitments to help them achieve their goals.
