Public bodies in the UK spend around £300bn a year, and since February 2025 the rules were rewritten to make it easier for small firms to get a share. This is what changed, where to look, and how to bid without losing a week of evenings.
Most new notices — councils, housing associations, NHS trusts, schools, universities, utilities — go on the central digital platform, Find a Tender. The older site, Contracts Finder, still carries some below-threshold and legacy notices. Nobody reads both every day, which is why we built the Projects list: both feeds, filtered to building and building-services packages, tagged by trade and region, refreshed every morning. Start from your trade: electrical, M&E & heating, fit-out, roofing, civils, repairs & maintenance.
Supplier registration on Find a Tender is free. Have ready: company number, VAT number, turnover for the last two years, employer's and public liability insurance (most buyers ask for £5m / £10m), accreditations (NICEIC, Gas Safe, CHAS / SafeContractor / Constructionline), and two or three references with contact details. Buyers pull these from the register, so you stop re-typing them in every bid.
The Act makes buyers consider barriers to small firms and justify them. In practice that means you can reasonably ask for: payment within 30 days (it's in the Act and must flow down the supply chain, including to you as a subcontractor), lots sized for a firm your size, proportionate turnover requirements (the long-standing benchmark is no more than twice the contract value), and clarification questions answered in writing for everyone. Use the questions period — buyers must publish answers to all bidders, and a good question often reveals who the incumbent is and how they'll score.
Public work is paperwork-heavy: RAMS before you start, inductions signed, daily records, test certificates, O&M files and valuations every month. That's what Graftum was built for — site records from the phone, timesheets and CIS pay from the same data, valuations that match the contract lines, and a handover pack at the end. It's free for 90 days, and the Projects list stays free regardless.
285+ public-sector packages, filtered to construction, refreshed every morning.
Thresholds and rules are as published for England, Wales and Northern Ireland at 30 October 2026; Scotland runs its own regime via Public Contracts Scotland. This is general guidance, not legal advice.
