The public sector procurement landscape is built on precision, compliance, and clarity. For suppliers, navigating this environment means that a winning tender submission is often defined not just by a competitive price, but by the flawless execution of the bid itself. Crafting a winning tender response requires a structured bid writing process, where careful planning, compliance, and expert support are essential to success. In a world governed by strict regulations, even the smallest oversight—a missing signature, a misread instruction, or a poorly formatted document—can lead to immediate disqualification. This means countless hours of work can be undone in an instant. Understanding and avoiding these common pitfalls is the first step towards transforming your bidding process from a source of frustration into a powerful engine for growth.
This article breaks down the most common and costly errors that suppliers make during the tender process. Bid writers play a crucial role in helping organisations fully understand and respond to buyer requirements, ensuring that every aspect of the submission meets the evaluation criteria. Bid writing is the process of creating persuasive and compelling proposals which answer the particular requests of a tender to assist you as you try to win a contract. By turning these mistakes into a checklist for success, you can significantly improve your win rate, ensure that your hard work receives the consideration it deserves, and establish a reputation as a reliable and professional partner to the public sector.
The High Cost of Small Errors in Your Tender Submission
Winning a public sector tender is about more than just having the best product or the lowest price; it’s about proving you are a low-risk, reliable, and diligent partner. Public sector buyers are custodians of taxpayer money, and their processes are designed to be fair, transparent, and auditable. Consequently, they are incredibly risk-averse and compliance-driven. Any deviation from the tender instructions, no matter how minor, can be grounds for your submission to be set aside without ever being fully evaluated.
This is where the real cost of small errors becomes apparent. It’s not just the disappointment of losing a contract; it’s the wasted investment of time, resources, and expertise that went into preparing the bid. Weeks of effort from your best people can be nullified by a simple mistake.
The good news is that these mistakes are almost always avoidable. By focusing your efforts on the right opportunities and approaching each submission with a meticulous process, you can dramatically increase your chances of success. The first step in any winning strategy is to ensure that your efforts are directed at tenders for which you are well-positioned to win. Using Tracker Intelligence helps you find the right opportunities well in advance, giving you the time to prepare a bid that is not only compelling but also perfectly compliant.

Mistake 1: Misunderstanding the Procurement Tender Process & Requirements
One of the most fundamental errors in the tender process is a failure to read and fully comprehend the tender documents. Invitation to Tender (ITT) or Request for Proposal (RFP) documents are often lengthy and complex, filled with specific instructions, legal clauses, and detailed evaluation criteria. A superficial skim-read is a recipe for a non-compliant bid.
This mistake often stems from suppliers being under pressure, leading them to search for keywords rather than digesting the full scope of the buyer’s needs. This can lead to a bid that answers the wrong question or misses a critical requirement entirely. A common point of confusion is the distinction between mandatory pass/fail criteria and scored questions. Mandatory requirements, such as specific certifications (like ISO 9001), minimum turnover levels, or signed declarations, are non-negotiable. If you don’t meet them, your bid will be disqualified before the evaluation stage even begins. Scored questions, on the other hand, are where you compete on the quality of your response. Misinterpreting a mandatory requirement as optional is a fatal error.
To avoid this, dedicate time to a thorough review of every document. Create a checklist of all requirements, deadlines, and formatting rules. If anything is unclear, use the official clarification question period to ask the buyer directly. It is always better to seek clarity than to make an assumption that could derail your entire submission.
Mistake 2: A Poorly Structured or Incomplete Supplier Tender
Beyond understanding the requirements, the practical assembly of your supplier tender is where many bids fail. A submission that is missing documents, leaves questions unanswered, or is structured confusingly makes the evaluator’s job difficult and, more importantly, portrays your business as disorganised and unreliable. Remember, your submission is the buyer’s first impression of your ability to deliver a complex project.
Common errors include forgetting to attach a pricing schedule, neglecting to sign a form of tender, or failing to include a required insurance certificate. Each tender will specify the exact documents needed, and overlooking even one can lead to disqualification. Beyond missing documents, incomplete or inconsistent answers are major red flags. If a question has multiple parts, ensure you address every single one. If your technical proposal mentions a five-person team but your pricing only accounts for three, it undermines your credibility.
Failing to Answer the Question
A surprisingly common reason for low scores is simply not answering the question asked. A well-prepared tender response is tailored to the specific question and evaluation criteria. This frequently happens when suppliers rely on generic, copy-pasted content from previous bids. Evaluators are looking for a direct response to their specific needs, not a general overview of your company. If a question asks how your methodology will achieve a specific outcome, a response that only describes your methodology without linking it to the outcome will fail to score well. A simple but effective technique is to structure your response using the exact headings and keywords from the question, ensuring you cover every point the evaluator is tasked with scoring.
The Perils of Bad Formatting
Formatting guidelines in a tender document are not suggestions; they are rules. It is crucial to adhere to all formatting requirements, word limits, and specified requirements—such as word counts, font sizes, and layout—to ensure compliance with official guidelines and avoid penalties or disqualification. Ignoring instructions on page limits, word counts, font size, or file naming conventions can be interpreted as a failure to follow instructions, leading to your bid being marked down or even rejected. If a response is limited to 500 words, any text beyond that limit will likely be disregarded by the evaluator. These rules exist to ensure a level playing field, and adhering to them demonstrates your attention to detail. A clean, professional, and well-organised submission that respects all formatting rules makes it easier for the evaluator to find the information they need and score your bid favourably.
Mistake 3: Not Providing Evidence to Support Your Claims
In public procurement, claims are meaningless without proof. A common mistake is to fill a tender with ambitious marketing statements like “we deliver an industry-leading service” or “we are committed to innovation” without providing any evidence to back them up. Evaluators are trained to look for tangible proof of capability, not just promises. Your bid needs to convince them that you are a safe and credible choice.
Instead of making generic claims, provide concrete data and examples. Rather than saying you offer “excellent customer service,” state that you “achieved a 98% on-time delivery rate and a 4.8/5 client satisfaction score last year.” This transforms a vague assertion into a verifiable fact. The most powerful evidence comes from your track record. Include concise case studies from relevant past projects, highlighting the outcomes you achieved. Use key performance indicators (KPIs), client testimonials, and third-party accreditations (like ISO standards or industry awards) to build a compelling case.
This evidence-based approach is crucial for differentiation. When a buyer is comparing two similar proposals, the one that can prove its approach works will always have the advantage. Treat every claim you make as an opportunity to provide proof, and you will build a narrative of a trustworthy and highly capable supplier.
Mistake 4: Generic Content vs. Bespoke Bidding: What is Tender Writing?
Tender writing is the professional skill of crafting a customised, compliant, and persuasive response that speaks directly to a single buyer’s unique needs. This is not about recycling marketing brochures or copying and pasting from old submissions. A generic, “one-size-fits-all” bid is easy for an experienced evaluator to spot, and it immediately signals a lack of genuine interest and effort.
The most effective bids are meticulously tailored. This means going beyond simply inserting the buyer’s name. It involves researching the contracting authority to understand their strategic goals, challenges, and priorities, and then framing your solution in that context. If a local council has a stated commitment to achieving Net Zero, for example, your proposal should detail how your solution contributes to that specific goal.
A bespoke bid uses the buyer’s own language and terminology. It mirrors the structure of their questions and directly addresses the pain points mentioned in the specification. While it is efficient to maintain a library of pre-written content, every section should be reviewed and adapted for each new tender to ensure it is 100% relevant. This tailored approach demonstrates a deep understanding of the buyer’s world and positions your offer not as a generic product, but as a specific solution to their problem.
Mistake 5: An Uncompetitive or Unsustainable Pricing Strategy
Pricing is one of the most critical elements of any tender, and mistakes here can be fatal. The most obvious error is pricing too high and being uncompetitive. However, pricing too low can be just as damaging. An “abnormally low” tender raises red flags for buyers, who may suspect you have misunderstood the scope or that your business model is unsustainable. Under UK procurement regulations, they are required to investigate such bids and can reject them if a credible justification cannot be provided. A bid is a formal offer to supply goods or services at a specified price, usually describing how the contract requirements will be met.
The goal is not to be the cheapest, but to offer the best “value for money.” Following the implementation of the Procurement Act 2023, tenders are awarded based on the Most Advantageous Tender (MAT), which is a holistic assessment of price, quality, and other factors like social value. Value for Money (MEAT) emphasizes the best balance of cost and quality over the contract’s life. A higher-priced bid that demonstrates significantly better quality or long-term benefits can easily beat a cheaper competitor.
Equally important is the clarity and accuracy of your pricing submission. Arithmetic errors in your cost breakdown, missing line items, or unexplained assumptions can lead to disqualification. Always use the provided pricing schedule and double-check all your calculations. Your pricing should tell a coherent story that aligns with your technical proposal, justifying the investment and demonstrating clear value for the public purse. A well-prepared bid increases your chances of securing contracts and a successful contract award.
Unique Challenges of Bidding for Government Tenders UK
Bidding for public sector contracts in the UK is fundamentally different from commercial sales. Contracting authorities are responsible for issuing tender documents and overseeing the process. The process is governed by a strict legal framework designed to ensure fairness and transparency. This creates a unique environment with specific challenges that suppliers must navigate. The tendering process is often the key route for businesses looking to win longer term contracts with larger organisations. During the submission phase, potential suppliers submit their bids in response to the tender documents. The evaluation phase involves assessing bids to find the most suitable supplier based on predefined criteria. After the contract award, the post-evaluation phase includes finalising the contract with the selected supplier and managing the contract effectively.
The Importance of Social Value
Social value is no longer a “nice-to-have”; it is a mandatory and scored component of UK government tenders, typically accounting for at least 10% of the overall score. Failing to provide a specific, credible, and relevant social value offer is akin to leaving a tenth of your marks on the table. Vague statements like “we will support the local community” will score poorly. Buyers expect concrete, measurable commitments, such as hiring a specific number of local apprentices, reducing carbon emissions by a verifiable amount, or dedicating volunteer hours to a local charity. Your social value offer should be tailored to the priorities of the contracting authority and the community it serves.

Navigating Official Portals
Nearly all UK public tenders are managed through e-procurement portals. Each portal has its own interface and technical requirements. Waiting until the last day to familiarise yourself with a new portal is a significant risk. Technical glitches, slow upload speeds, or forgotten passwords can easily cause you to miss the deadline. Always register on the portal well in advance, check for file size limits, and do a test upload if possible. Treat the portal as a critical part of the compliance process.
The Final Hurdle: Submitting Late
There is no mistake more final or more absolute than submitting your tender late. In public procurement, deadlines are rigid and non-negotiable. A submission received even one second past the deadline will almost certainly be rejected, regardless of the reason. The system is designed to be fair to all bidders, and making an exception for one would compromise the integrity of the entire process.
The only way to avoid this is through disciplined project management. Plan your bidding process backwards from the submission date, setting an internal deadline at least 24 hours in advance. This buffer provides a crucial safety net for any last-minute technical issues or unforeseen delays. Break the work down into manageable stages with their own deadlines—for drafting, review, and final sign-off. On the day of submission, aim to upload all documents several hours early, and always save the electronic receipt or confirmation as proof of timely submission.
A Proactive Approach: How to Make a Tender Submission that Wins
Avoiding the common mistakes detailed above is the foundation of any successful bidding strategy.
