Battery Tenders and Contracts

Battery storage tenders cover grid-connected battery energy storage systems, from supplying the battery to building a storage site, and solar PV installations with batteries at schools, hospitals, housing and community buildings. Storage containers and feasibility studies also appear.

Stotles brings together battery storage tenders and contracts from 100+ portals into one search, so you do not have to check each portal separately, and you can set alerts for new opportunities across the UK and Ireland.

If you want to search the government portals directly, Find a Tender carries higher-value contracts across the UK and Contracts Finder carries lower-value contracts in England. Public Contracts Scotland, Sell2Wales and eTendersNI cover Scotland, Wales and Northern Ireland, Ireland's eTenders covers Irish public bodies, and many councils, NHS bodies and housing associations publish on their own e-tendering portals such as ProContract. Solar and battery installs are often called off from decarbonisation and retrofit frameworks, such as those run by Procurement for Housing, so some opportunities reach only installers already on them.

Battery storage tenders are scored on system design and performance, safety, grid connection, warranties and whole-life cost. Most are bundled with solar PV, so installers that can deliver both are better placed.

Battery installations must meet electrical safety requirements under BS 7671 and fire safety guidance for battery energy storage, and grid-connected systems need distribution network operator approval. Tenders usually set minimum insurance cover, check financial standing and ask for evidence of similar installations at selection stage. Under the Procurement Act 2023, suppliers can be excluded for certain criminal convictions, insolvency or failure to pay tax.

Battery storage contracts are mostly let as design-and-build contracts that bundle the battery with a solar PV installation, rather than a standalone battery purchase. A single tender typically covers design, supply, installation, commissioning and sometimes ongoing maintenance. Larger grid-scale sites and multi-site framework programmes also appear.

Councils, NHS trusts, housing associations, universities and utilities tender for battery storage, usually as part of a decarbonisation or net zero programme.

Read decarbonisation plans, net zero strategies, energy and estates investment programmes and feasibility studies, since battery storage is often bundled into a wider solar PV or energy programme. On Stotles you can track those signals and the buyers behind them, then follow a notice from pre-tender through to award.

CPV 31422000 (Battery packs) is the code most specific to the physical battery, while 09330000 (Solar energy) appears widely because many battery storage projects are bundled with a solar PV installation. Neither code is specific to battery storage on its own.
