The agreement, valued at £3m, encompasses various lots including annular sealants, leakage sealants, bar hole sealing, flow stopping, and live insertion. It operates within the utilities sector and adheres to Gas Industry Standards, with deliveries planned across regions in the UK. The awards were declared on 27th March 2026, and the contracts will commence from 27th April 2026, lasting up to 29th April 2029, with possible extensions. Northern Gas Networks Limited, headquartered in Leeds, is the buyer organisation responsible for overseeing this supply continuity, conducting supplier evaluations and awarding the contracts based on specified criteria. This tender presents substantial business growth opportunities for suppliers, particularly SMEs specialising in sealant production and associated equipment for gas industry applications. The framework's structure allows suppliers to bid for one or multiple lots, increasing competitiveness and flexibility for business expansion. Businesses with capabilities to meet rigorous industry standards and diverse regional delivery can significantly benefit from this framework by securing contracts that promise sustained engagement and potential extensions. The procurement process involves a selective method with staged evaluations, offering firms transparent pathways to compete and succeed within the utilities market. ## Notice The products under this Framework Agreement are used throughout the NGN network. The purpose of this framework is to ensure continuity of supply of the sealant and associated equipment to the business at agreed rates and lead time and to ensure products conform to the correct specification and standards. The items under the framework agreement met the necessary Gas Industry Standards, LC9, LC12 and LC24, but there was a national strategy group considering if there was a requirement for the sealant to be manufactured to British Standards. In September 2022 new guidance and standards were published. This event was conduced under PA23 - PR24. The scope was split into 5 lots, indicated below: Lot 1 - Annular sealants Lot 2 - Leakage Sealants Lot 3 - Bar Hole Sealing Lot 4 - Flow Stopping Lot 5 - Live Insertion Interested suppliers were able to bid for any of the lots. This means they can bid for one or all or anything in between. This Framework value is estimated at PS3m for the lifecycle of the contract. ### Lot Information Lot 1 - Annular sealants Renewal: 3 year initial term with the option to extend a further 5 x 1 years thereafter Lot 2 - Leakage Sealants Renewal: 3 year initial term with the option to extend a further 5 x 1 years thereafter Lot 3 - Bar Hole Sealing Renewal: 3 year initial term with the option to extend a further 5 x 1 years thereafter Lot 4 - Flow Stopping Renewal: 3 year initial term with the option to extend a further 5 x 1 years thereafter Lot 5 - Live Insertion Renewal: 3 year initial term with the option to extend a further 5 x 1 years thereafter ## Key Details | Field | Value | | --- | --- | | Publication source | Find A Tender Service | | Latest notice | https://www.find-tender.service.gov.uk/Notice/033707-2026 | | Notice type | UK6 - Contract Award Notice | | Procurement type | Framework | | Procurement category | Goods | | Procurement method | Selective | | Procurement method details | Competitive flexible procedure | | Tender suitability | Not specified | | Awardee scale | SME | | All stages | Tender, Award | ## Dates | Field | Value | | --- | --- | | Publication date | 14 Apr 2026 | | Submission deadline | Not specified | | Future notice date | Not specified | | Award date | 27 Mar 2026 | | Contract period | 26 Apr 2026 - 26 Apr 2029 | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | £3,000,000 | | Lots value | £3,000,000 | | Awards value | £3,000,000 | | Contracts value | Not specified | ## Status | Field | Value | | --- | --- | | Tender status | Complete | | Lots status | Complete | | Awards status | Pending | | Contracts status | Not specified | ## Buyer | Field | Value | | --- | --- | | Main buyer | NORTHERN GAS NETWORKS LIMITED | | Locality | COLTON LEEDS | | Post town | Leeds | | Postcode | LS15 8TU | | Country | England | | ITL 1 | TLE Yorkshire and The Humber | | ITL 2 | TLE4 West Yorkshire | | ITL 3 | TLE42 Leeds | | Local authority | Leeds | | Electoral ward | Garforth & Swillington | | Westminster constituency | Leeds East | | Delivery location | TLC North East (England), TLD North West (England), TLE Yorkshire and The Humber, TLF East Midlands (England), TLG West Midlands (England), TLH East (England), TLI London, TLJ South East (England), TLK South West (England) | ## Supplier | Field | Value | | --- | --- | | Number of suppliers | 5 | | Supplier names | A L H SYSTEMS; CHEMENCE; GAS SEALING SOLUTIONS; M.W.
