Public sector contracts can transform a small business, but mastering how to write a business plan is only the start, since the tendering process is complex, fast-paced and full of compliance traps. Winning even a small slice of public sector spend can provide steady revenue and credibility. For women-led businesses, which the 2019 Alison Rose Review of Female Entrepreneurship estimates make up around 20% of UK SMEs, tendering is a route worth understanding.
ThThis guide explains how public sector tendering works under the current UK regime, what has changed, and how to prepare a compliant, competitive bid, including what is a limited company.hat the tendering process means
Public sector organisations must advertise contracts above set value thresholds and award them in a fair, open and transparent way. Prospective suppliers then submit a bid, which is evaluated against quality and price criteria.
The words “tender” and “bid” are used interchangeably. Contracting authorities may also use “request for tender” (RFT), “request for proposal” (RFP) or “invitation to tender” (ITT). Under the current regime, you will most often see a simple “tender notice” published on the relevant procurement portal.
The most time-intensive element is usually responding to the quality questions or method statements. These are forward-looking: they ask how you propose to deliver the contract, not simply what you have done before.
The new UK procurement regime
The Procurement Act 2023 came into force on 24 February 2025, replacing the previous regulations that were derived from EU law. The Act applies to most public sector contracting authorities in England, Wales and Northern Ireland. Scotland retains its own procurement rules, although many principles overlap.
The Act introduced two main tender procedures:
- Open procedure: all interested suppliers submit a full bid at the same time. This remains the default for many contracts and is the closest to the old open procedure.
- Competitive flexible procedure: the buyer designs a staged process that is “fit for purpose” for the particular contract. This replaces the old restricted procedure and gives authorities more discretion over how they shortlist and evaluate bidders.
Buyers must still publish notices, set clear award criteria, and treat suppliers transparently. The new regime also introduces a single public procurement register, making it easier to track opportunities and outcomes.
When must a contract be tendered?
Public procurement thresholds are reviewed every two years. Most public sector contracts for goods and services must be advertised if they are above set financial thresholds, which differ for central government bodies and sub-central authorities such as local councils, NHS trusts and universities. Works contracts have a separate, higher threshold. Check the current figures on gov.uk Procurement Act 2023 guidance before deciding whether an opportunity is regulated.
Contracts below these thresholds can often be procured through simpler routes, such as direct award or framework agreements. However, many authorities still choose to advertise lower-value opportunities to meet the government’s target of directing a substantial share of central government procurement spend to SMEs.
Given that SMEs account for 99.9% of the UK business population, according to the ONS Business Population Estimates for 2024, this target matters. Women-led businesses are a significant part of that SME base, and public sector tendering can be a powerful growth lever.
Steps for submitting a high-quality tender
Every tender is a competition. Your job is to prove you offer the best solution and value for money. With word or page limits common, every sentence must earn its place.
Analyse the opportunity before deciding to bid
The “bid/no-bid” decision is crucial. Once the tender documents are released, review:
- Minimum criteria or thresholds, such as turnover, insurance levels or mandatory accreditations like ISO 9001, Cyber Essentials or sector-specific licences.
- Anticipated volume and location, ensuring you have the resource to deliver the scope of works.
- Contract structure, including whether it is a single-supplier contract, a framework agreement or a dynamic purchasing system.
- The specification, noting any unusual or high-risk requirements.
Involve the right people before committing. A bid that stretches your team too thin can damage both your submission and your existing client work.
Compile all submission documents
Most tender packs include a submission checklist. Documents typically required are:
- Selection questionnaire (SQ): the modern replacement for the pre-qualification questionnaire, covering financial standing, insurance, technical capacity and exclusion grounds.
- Pricing schedule or rate card: where you submit costs for each element of the contract.
- Quality questions or method statements: forward-looking responses covering mobilisation, health and safety, customer care, quality assurance, social value and similar themes.
- Form of tender and certificates: signed declarations confirming your bid is genuine and non-collusive.
Assign a task owner and internal deadline for every document. A shared tracker prevents last-minute gaps.
Schedule adequate time for quality responses
Quality responses usually take the longest. Calculate the total word or page count, then assign writers with relevant expertise. A contract manager should review technical answers; a finance colleague should check pricing.
After drafting, ask a second person to review for accuracy, consistency and persuasiveness. Look for the “why” behind each response: not just what you will do, but why it benefits the buyer.
Check compliance before submitting
Bidders rarely get a second chance. At least 24 hours before the deadline, check:
- There are no blank fields or missing attachments.
- Job titles, company names and dates are consistent across all documents.
- Responses stay within word or page limits.
- Appendices and evidence are submitted in the requested format.
- The submission is uploaded to the correct portal before the deadline, allowing for technical delays.
After the outcome, save all feedback. Even unsuccessful bids produce useful lessons: a high-scoring mobilisation response can be repurposed for the next tender.
Where to find tender opportunities
The main UK portals are:
- Find a Tender: the UK-wide service for high-value public sector notices.
- Contracts Finder: for lower-value England-based opportunities.
- Public Contracts Scotland, Sell2Wales and eTendersNI: the devolved nation portals.
Many local authorities and NHS trusts also publish opportunities on their own websites. Set up email alerts on the relevant portals and review them weekly.
Action steps
- Register on Find a Tender and the relevant devolved or sector-specific portals.
- Prepare a bid library of standard documents: insurance certificates, accreditations, case studies, policies and financial accounts.
- Review the Procurement Act 2023 guidance on gov.uk so you understand your rights and the buyer’s obligations.
- Use a bid/no-bid checklist to avoid chasing opportunities that do not fit your business.
- Build time into every tender for a final compliance review at least 24 hours before submission.
Public sector tendering is competitive, but it is also one of the most accessible routes to long-term revenue for women-led businesses. By understanding the tendering process, preparing strong evidence and following a disciplined submission routine, you can turn public procurement into a reliable growth channel.
