With a large, highly trained workforce and an advanced in-house control room operating 24 / 7 / 365, we deliver outstanding protection for land, property, infrastructure, and the people who rely on them.

Our reputation is built on reliability, innovation, transparency, and exceptional service delivery—qualities recognised through industry awards and long-standing client partnerships. As we continue to grow across the UK, we are now seeking a talented Bid Manager to support our continued expansion.

• Review tender documentation to understand client requirements, specifications, pricing templates, and evaluation criteria.
• Collaborate with operational managers, regional leads, and the control room team to gather and structure technical content.
• Develop win themes, solutions, and differentiators aligned to Land Sheriffs’ operational strengths and innovation.
• Coordinate bid schedules, ensuring the timely delivery of all submissions, supporting documents, and clarifications.
• Produce case studies, CVs, risk assessments, mobilisation plans, and method statements tailored to each tender.
• Work with finance and leadership teams to support pricing exercises and commercial strategy.
• Maintain and enhance the company’s bid library, templates, and best-practice documentation.
• Prepare presentation material for post-tender clarification meetings and client interviews.

• Proven experience as a Bid Manager, Bid Writer, Proposal Manager, or Commercial Manager within security, FM, rail, or safety-critical services.
• Strong understanding of security service delivery models (e.g., manned guarding, patrols, rapid response, control room operations).
• Excellent written English with the ability to turn technical information into persuasive, client-focused content.
• Highly organised and able to manage multiple bids concurrently under tight deadlines.
• Strong communication and stakeholder engagement skills.
• Ability to work independently while remaining collaborative with operational teams.
• High level of IT competency (Word, Excel, SharePoint, document management).
• Understanding of public sector procurement processes (e.g., rail, local authority, utilities) is advantageous.

• Competitive salary (up to senior-level depending on experience)
• Hybrid working model – flexibility to work from home 4 days weekly
• Opportunity to shape major UK-wide bids in a respected, growing organisation
• Supportive and collaborative leadership team
• Career development and training opportunities
• 25 days holiday + bank holidays
• Pension scheme and additional benefits
