How Thornton & Lowe can help you

This is a practical working session tailored to your company, your services and the contracts you want to secure.

It is suitable for NSI Approved Companies operating across security systems, fire safety, guarding, monitoring and other specialist security services.

Depending on your current position, we can help you with:

✔️ Assessing your readiness for the public sector frameworks, private sector tenders and larger contracts you want to pursue

✔️ Identifying suitable opportunities based on your services, experience, location, resources and growth plans

✔️ Reviewing the policies, accreditations, case studies, performance data and supporting evidence available for your bids

✔️ Presenting your NSI approval and technical credentials clearly within tender responses rather than relying on certification alone to demonstrate your strengths

✔️ Improving method statements covering areas such as mobilisation, service delivery, quality assurance, risk management, incident response, business continuity and contract management

✔️ Strengthening case studies so that they demonstrate relevant outcomes, challenges, results and lessons learned

✔️ Approaching social value, sustainability, workforce development and community benefits in a way that is realistic for your organisation

✔️ Deciding whether a tender is worth pursuing before committing significant time and resources

✔️ Understanding buyer feedback or discussing questions from a current tender

✔️ Agreeing your priority actions for the next 30 to 60 days

Turn Your Technical Credentials Into Stronger Tender Evidence

NSI approval provides valuable independent assurance of your company’s technical competence, quality and commitment to recognised standards.

However, buyers will still expect you to explain how your systems, people and procedures will support the specific contract they are procuring.

A strong tender needs to connect your credentials with practical delivery. This may include explaining:

How you will mobilise the contract
How your service will be managed and monitored
How you recruit, screen and develop your people
How incidents, faults and service risks will be controlled
How you maintain quality across different sites or regions
How performance will be reported to the customer
How you will provide continuous improvement throughout the contract

Thornton & Lowe can help you identify where this evidence already exists, where there may be gaps and how it can be presented more effectively.

Why This Support Is Available Through NSI Advantage

NSI helps approved companies demonstrate that they meet recognised technical, operational and quality standards across the fire and security sectors.

Through NSI Advantage, approved companies can also access trusted services and business support designed to help them develop and grow.

Thornton & Lowe specialises in helping businesses secure work through tenders, frameworks and formal procurement processes. We support organisations with bid writing, tender reviews, framework applications, bid strategy and outsourced bid management.

This partnership brings the two areas together. Your NSI approval demonstrates the standards behind your service, while Thornton & Lowe helps you communicate your strengths clearly and persuasively to buyers.
