A practical 2026 guide for small contractors: where tenders are published, how to filter for your trade, and how to set up daily alerts so you never miss an opportunity.
2026 guide · For small and micro contractors · Updated October 2026
The UK public sector spends billions on construction and maintenance every year, and much of it must be openly advertised. The challenge for small contractors is not a shortage of work — it is knowing where to look, how to filter out irrelevant notices, and how to hear about new contracts before your competitors do.
A tender is a formal invitation from a public body — a local council, NHS trust, housing association, school, or government department — asking contractors to submit a price and method statement for a piece of work. Because public bodies are spending taxpayers' money, procurement law requires them to run competitive processes and, above certain value thresholds, to advertise contracts openly.
For construction, this covers everything from a £15,000 school boiler replacement to a £50 million hospital expansion. Small contractors most commonly win maintenance and repair contracts, minor works, and specialist subcontract packages — often in the £20,000–£500,000 range.
There is no single place where all UK construction tenders appear. They are spread across several portals depending on the contracting authority and the size of the contract.
Checking all of these manually every morning is time-consuming. A tender alert service aggregates them so you receive one filtered email instead of visiting six websites.
Raw procurement portals publish hundreds of notices a day across all sectors — IT, healthcare, education, and construction lumped together. To find what is relevant to you, use three filters:
CPV stands for Common Procurement Vocabulary — a standardised European classification system that all public buyers must use. Construction trades each have a CPV code. A few commonly used ones:
| Trade | CPV code range |
|---|---|
| General building construction | 45200000–45213000 |
| Roofing and cladding | 45260000–45261420 |
| Electrical installation | 45310000–45316213 |
| Plumbing and drainage | 45330000–45332400 |
| Roads and groundworks | 45230000–45236290 |
| Painting and decorating | 45440000–45442190 |
Search for your specific specialism — "asbestos removal", "flat roof", "mechanical and electrical" — to catch notices where the buyer has used descriptive language rather than relying purely on CPV codes. Buyers do not always classify correctly.
Set a minimum value to filter out tiny one-off purchases, and a realistic maximum to avoid chasing contracts you cannot staff. For most small contractors, £20,000–£2,000,000 is a sensible starting range.
Winning a tender is not just about price. Public buyers evaluate quality and price together, often using a 60/40 or 70/30 quality-to-price ratio. Three things that consistently separate winning bids from losing ones:
The biggest competitive advantage in construction tendering is speed. Many invitation-to-tender periods last only two to four weeks. Finding out about a contract on day one rather than day fourteen gives you time to assess it properly, visit the site if needed, and write a considered submission.
