Fabrication and Machining Framework

United Kingdom National Nuclear Laboratory Limited · Public undertaking

In brief

United Kingdom National Nuclear Laboratory Limited has announced plans to buy construction and building maintenance work. This is an early notice: there is nothing to bid on yet, but it tells you a tender may follow.

It is a framework worth up to £10,000,000 excluding VAT: the most the buyer expects to spend across all suppliers, not one contract.

The contract runs for 8 years, starting 21 August 2026.

The buyer says it is suitable for small and medium-sized businesses.

Built from the notice's own fields. Always check the official notice before you bid.

Can I win this?

Competition

Usually high: a median of 12 bids per contract for this buyer (from 13 awards in the last 12 months).

Framework

Winning puts you on a list of suppliers the buyer can call on; it does not guarantee work. The £10,000,000 is the most the buyer expects to spend across all suppliers over the framework's life, not one contract.

What the notice says

United Kingdom National Nuclear Laboratory is undertaking pre-market engagement to inform the development of a Fabrication and Machining framework, structured as a multi-lot arrangement to support both nuclear and non-nuclear requirements. The framework is intended to provide access to suitably qualified suppliers, capable of delivering a range of fabrication and machining services, which may include (but are not limited to): - precision machining; - coded welding; - specialist fabrication; - component manufacture; - repair and modification activities; - associated quality, inspection and documentation services.

How to bid

  1. Read the full notice on Find a Tender, including any tender documents it links to.
  2. Register your organisation on the Central Digital Platform (through Find a Tender) if you have not already. Suppliers need to be registered to take part in procurements under the Procurement Act 2023.
  3. Follow the submission instructions in the notice; it does not name an e-tendering portal.
