Construction materials tenders cover the aggregates, timber, steel, plumbing and electrical stock and other products that housing associations with their own repair teams, highways authorities and councils buy. This page shows live notices and the product marking rules buyers check, and explains how merchants, quarries and manufacturers can win supply contracts, including through frameworks and dynamic markets. Our tender eligibility checker is coming soon. Until then, tell us your trade and postcode to join the free weekly list of live tenders, starting soon. If you are not sure which CPV codes cover your products, find your CPV codes.
What buyers usually ask materials suppliers for
The questions below have a legal basis. The tender pack sets out everything else.
Product marking in Great Britain
Government guidance says the CE mark continues to be available for construction products in Great Britain, and the UKCA mark can also be used. If you use UKCA for products covered by a designated standard, you need testing and certification from a UK approved body. Those bodies are listed on the UKMCAB database. The government’s sector table shows UKCA or CE accepted for construction products. The long-term position depends on wider reforms, so check the page before you rely on it. Northern Ireland has separate arrangements that we don’t cover here.
Expect to be asked for the marking and test evidence for what you supply. What exactly goes in the response is in the pack.
Steel
Central government has issued guidance on procuring steel, PPN 022. If you supply steel to a central government buyer, read it so you know what the buyer has been told to consider. We don’t summarise it here.
Delivery capability, coverage area and stock
Materials contracts are often defined by what the lot covers: which products, which sites and how quickly. Be clear on your delivery radius, stock levels, lead times and what happens when an item is out of stock. If you can’t serve every site in the lot, bid for a lot you can, or say so.
Insurance, turnover and environmental credentials
Product liability cover, minimum turnover and environmental policies vary by contract. We can’t source typical figures. Check the pack. See turnover tests.
Most of this is not in the notice itself. In the week to 10 Oct 2026, 29 of the 470 live notices in our data (about 6%) stated insurance requirements (as of 10 Oct 2026). That’s why the pack matters: we flag points a notice leaves vague, but we cannot see what it does not mention.
How to win construction materials contracts
Dynamic markets (formerly dynamic purchasing systems)
A dynamic market is a set of arrangements a buyer sets up to award contracts to member suppliers. Before establishing one, the buyer must publish a dynamic market notice. Once it is running, the rules on membership in section 36 work in a supplier’s favour:
- the buyer must accept applications to join at any time, consider them within a reasonable period, and admit suppliers that meet the conditions and aren’t excluded
- conditions for membership must be a proportionate means of checking legal and financial capacity and technical ability
- a buyer can’t require audited accounts unless you are legally required to have your accounts audited, and can’t require insurance to be in place before a contract is awarded
- a buyer can’t require you to have been awarded a contract by that particular authority
Because a buyer can limit a competition to members of an appropriate dynamic market, apply as soon as you can rather than waiting for a contract you want. See how dynamic markets work.
Frameworks and lots by product or area
Buyers must consider lots, or give reasons for not using them. A materials contract may be split by product group, depot or area. A framework’s term is limited to four years in most cases, so you can plan for the next opening. Bid for the lots where your stock, pricing and delivery range are strongest, not for everything on the list.
Supplies thresholds and below-threshold buying
From 1 January 2026, a contract for goods falls under the full Act rules at £135,018 including VAT for central government authorities and £207,720 including VAT for sub-central ones. Below that, when a buyer invites tenders it can’t restrict who may tender by assessing suppliers’ suitability (Welsh devolved buyers follow their own rules, and call-offs from frameworks are excluded).
If a buyer advertises a below-threshold contract worth £12,000 or more (central government, including NHS trusts) or £30,000 or more (other authorities), including VAT, it must first publish a below-threshold tender notice. Buyers can also invite quotes from chosen suppliers without advertising. That makes smaller local supply contracts a realistic starting point for a merchant or manufacturer.
Price for the whole contract
Supply bids can be won or lost on delivery terms, minimum order quantities and how price changes are handled during the term. Check how the pack treats those before you quote, and don’t offer a price you can’t hold for the full term.

Questions
Do my products need UKCA marking to supply a UK council?
Not necessarily. For construction products in Great Britain, the government says CE marking continues to be available and the UKCA mark can also be used. Products covered by a designated standard need testing or certification by the right approved body for the mark you use. Northern Ireland has separate rules that we don't cover here, so check the pack.
What is a dynamic market and how do I join one?
A dynamic market, formerly a dynamic purchasing system, is a set of arrangements a buyer sets up to award contracts to member suppliers. Buyers must accept applications to join at any time during the market's term, and must admit suppliers that meet the conditions and aren't excluded. The conditions must be proportionate: for example, a buyer can't require audited accounts unless you are legally required to have your accounts audited, or require insurance to be in place before a contract is awarded.
Can I bid for one product lot or one delivery area?
Often, if the buyer has split the contract. Buyers must consider lots, or give reasons for not using them. Look for lots by product group or area that match your stock and delivery range.
What is the threshold above which a supplies contract must follow the full Procurement Act rules?
For procurements starting on or after 1 January 2026, it is £135,018 including VAT for central government authorities and £207,720 including VAT for sub-central authorities. Below that, the below-threshold rules apply.
