The Lithium-ion Battery Safety Bill mandates new regulatory steps aimed at reducing the fire and safety risks of lithium-ion batteries across three fronts: grid-scale Battery Energy Storage Systems (BESS), electric micromobility vehicles and the online sale of goods that contain such batteries. It gives the Secretary of State a series of timelines to make regulations, requires planning authorities to consult safety regulators before approving stand‑alone BESS sites, and creates mandatory conformity-assessment and marking requirements for micromobility products.
The bill matters because it shifts compliance obligations upstream — onto online marketplaces, manufacturers, and importers — and creates explicit duties for planning and emergency services around BESS. It also centralises standard-setting and enforcement power in secondary legislation, allowing criminal offences and civil sanctions to be created by regulation.
That combination of delegated powers, tight deadlines and potential penalties will affect sellers, small manufacturers, conformity-assessment bodies and regulators, and could materially change how micromobility and battery products are placed on the UK market.
At a Glance
What It Does
Requires planning authorities to consult the Environment Agency, HSE and local fire services on stand‑alone BESS applications; requires the Secretary of State to make regulations for online marketplaces to verify lithium‑ion battery goods and to publish a list of authorised conformity assessment bodies (CABs) for micromobility products. The bill also mandates rules on conversion kits, charging systems, and disposal labeling, and permits criminal and civil penalties by regulation.
Who It Affects
Online marketplaces operating in the UK, manufacturers and importers of electric micromobility vehicles and conversion kits, developers and operators of stand‑alone BESS, conformity assessment bodies authorised by the Secretary of State, and local fire and rescue services consulted on planning.
Why It Matters
It ties product safety, planning and waste rules into a single battery-focused regime designed to reduce fire risk and boost public confidence — while using delegated regulations to set the technical details, enforcement tools and penalties that will determine compliance costs and market impacts.

What This Bill Actually Does
The bill sets out two statutory purposes: protect householders and communities from the dangers of lithium‑ion batteries and increase public confidence in Battery Energy Storage Systems (BESS). Those purposes must guide any public authority acting under the Act.
For BESS, planning authorities must consult the Environment Agency, the Health and Safety Executive and the local fire and rescue service before approving any stand‑alone BESS (whole or partly lithium‑ion). Separately, the Secretary of State has a 12‑month window to make regulations about environmental permits for stand‑alone BESS facilities, giving central government scope to impose permit conditions tailored to battery risks.
On product safety, the Secretary of State must within one year require operators of online marketplaces to take “reasonable steps” to ensure goods containing lithium‑ion batteries comply with the General Product Safety Regulations 2005 and any further safety requirements set by regulation. The marketplace duty also bars goods that have previously been the subject of certain enforcement notifications from being offered for sale.
The regulations can vary by product type and may create criminal offences and civil sanctions for noncompliance.The bill creates a short, targeted regime for micromobility vehicles. The Secretary of State must publish a list of authorised conformity assessment bodies (CABs) within six months.
Once the Secretary of State publishes that list, sellers will have three months to ensure e‑scooters, e‑bikes and their batteries have undergone conformity assessment by an authorised CAB, that the manufacturer has prepared technical documentation and a declaration of conformity, and that products bear the CE or UKCA mark. CABs that judge products meet essential safety requirements must issue a certificate of conformity; the Act makes it an offence to mark products falsely or place non‑certified products on the market, subject to supporting regulations.The Secretary of State must also make regulations (within 12 months) on conversion kits and charging systems used with micromobility vehicles, and consult within six months about whether to ban universal chargers until those regulations are in place.
On disposal, the Secretary of State must make regulations within six months requiring sellers to display prominent warnings about improper disposal and to attach information on cell chemistry and safe disposal at point of sale; those disposal rules may not impose additional financial burdens on local authorities. The Act contains standard provisions on delegated legislation, territorial extent (UK‑wide but requiring devolved consent for application in Scotland, Wales and Northern Ireland), commencement on enactment and definitions of key terms used throughout.
The Five Things You Need to Know
The Secretary of State must publish a list of authorised conformity assessment bodies for micromobility products within six months of enactment; three months after that list is published, no e‑scooter or e‑bike (or their batteries) may be placed on the UK market without CAB certification and CE/UKCA marking.
Online marketplace operators must, within one year, take reasonable steps to ensure items containing lithium‑ion batteries comply with the 2005 General Product Safety Regulations and are not products previously notified or subject to enforcement under specified EU/UK market‑surveillance rules.
Regulations across the Act may create criminal offences punishable by fines and may also provide for civil sanctions, leaving the scope and severity of penalties to secondary legislation.
The Secretary of State must make disposal regulations within six months requiring sellers to display prominent warnings and attach information on battery cell chemistry and safe disposal, but those regulations may not impose extra financial burdens on local authorities.
Planning authorities must consult the Environment Agency, HSE and the local fire and rescue service before approving stand‑alone BESS planning applications; the Secretary of State also has a 12‑month power to make environmental‑permit rules specific to BESS.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Statutory aims and decision‑maker duty
The Act opens by declaring two statutory purposes: protect householders and communities from lithium‑ion battery dangers and increase public confidence in BESS. It then requires anyone exercising functions under the Act to have regard to those purposes. Practically, this language creates a legal benchmark for regulators and courts to interpret subsequent provisions and to weigh competing policy goals during implementation.
Mandatory consultee list for stand‑alone BESS planning
Before approving planning applications for stand‑alone BESS that contain lithium‑ion batteries, a planning authority must consult three named bodies: the Environment Agency, the Health and Safety Executive and the local fire and rescue service. That is a procedural precondition: failure to consult could leave a planning approval open to legal challenge. The provision does not prescribe timing or consultation form, so practical implementation will depend on national planning guidance and local practice.
Secretary of State power to regulate BESS permitting
The Secretary of State receives an express power to make regulations about environmental permits for stand‑alone BESS within 12 months. This grants the executive flexibility to add permit conditions tailored to battery risks (for example operational plans, fire suppression, spacing, or end‑of‑life management) via secondary legislation rather than primary law, letting technical requirements be updated without another Act.
Due‑diligence and listing prohibitions for marketplace operators
Within one year the Secretary of State must require online marketplaces to take reasonable steps to ensure goods containing lithium‑ion batteries meet the 2005 General Product Safety Regulations and any additional standards set by regulation. Marketplaces must also prevent listings of goods that have been subject to specific enforcement notifications. The bill allows regulation to be product‑specific and to create criminal and civil sanctions, meaning compliance will require marketplaces to enhance vetting, record‑keeping and takedown processes and to align with market‑surveillance databases.
CABs, certificates of conformity and CE/UKCA marking
The Secretary of State must publish a list of CABs within six months; three months after that publication, micromobility vehicles and their batteries cannot be placed on the UK market unless assessed by an authorised CAB, the manufacturer has prepared technical documentation and a declaration of conformity, and the product bears a CE or UKCA mark. CABs must issue certificates when they consider essential safety requirements are met, and the Act bars marking without such a certificate. The timing compresses manufacturers’ and importers’ compliance windows and creates demand for accredited CAB capacity.
Standards for conversion kits and charger types; consultation on universal chargers
The Secretary of State must make regulations within 12 months setting safety standards for conversion kits and for proprietary or non‑proprietary charging systems. Separately, the Secretary must consult within six months about whether to prohibit the sale of universal chargers until those regulations are in force. These measures aim to reduce risks from mismatched or uncertified charging systems but raise interoperability and market‑access questions depending on the outcome of the consultation.
Seller labeling and information at point of sale; limits on local authority costs
Disposal regulations must be made within six months and require sellers to display prominent warnings about improper disposal and to attach information on battery cell chemistry and safe disposal with sales. Critically, the Act forbids regulations that impose additional financial burdens on local authorities, directing that implementation should not shift new collection costs onto councils — a constraint that will shape how disposal responsibilities are allocated.
Key term definitions, delegated legislation, territorial limits
The bill supplies working definitions for terms such as 'conversion kit', 'electric micromobility vehicle', 'lithium‑ion battery' and 'stand‑alone BESS'. Regulations are to be made by statutory instrument and subject to annulment ('negative resolution' style). The Act extends to the whole UK but requires each devolved legislature to pass a resolution agreeing to its application in Scotland, Wales and Northern Ireland, and the Act comes into force on the day it is passed.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Householders and nearby communities — they gain an express statutory focus on battery safety around homes and formal consultation on stand‑alone BESS siting, which should improve risk assessment and emergency planning.
- Local fire and rescue services and emergency responders — the consultation requirement gives them a statutory role in planning decisions affecting BESS, improving early involvement in site mitigation and response planning.
- Consumers of micromobility devices — mandatory conformity assessments, technical documentation and marking aim to reduce unsafe or counterfeit e‑scooters and e‑bikes entering the market, increasing safety and consumer confidence.
- Accredited conformity assessment bodies (CABs) — authorised CABs will see increased demand for certification services from manufacturers and importers seeking to place micromobility products on the UK market.
- Waste management and recycling operators — clearer seller responsibilities and required disposal information should improve collection and sorting of lithium‑ion batteries, reducing uncontrolled disposals and associated fire risks.
Who Bears the Cost
- Online marketplace operators — they must implement vetting, record‑keeping and takedown procedures to ensure listings comply with product safety rules and to exclude items previously subject to enforcement, increasing compliance costs.
- Micromobility manufacturers, importers and aftermarket sellers — they must secure CAB assessments, prepare technical documentation and affix CE/UKCA marks within tight timelines, which raises testing and certification expenses and could delay market entry.
- BESS developers and operators — the additional planning consultation and forthcoming permit requirements may add procedural steps, mitigation obligations and permit conditions that increase project timelines and capital costs.
- Regulators and enforcement bodies (Environment Agency, HSE, local fire services) — they face increased consultation and oversight responsibilities without specified new funding, stretching resources for review, permitting and enforcement.
- Small sellers and second‑hand markets — the requirement for CAB certification and marketplace vetting could disproportionately affect informal sellers, peer‑to‑peer platforms and low‑volume traders who lack resources for formal compliance.
Key Issues
The Core Tension
The central dilemma is between improving safety and preserving market access: the bill advances robust, evidence‑based steps to reduce battery fire risk, but does so by shifting costs and procedural burdens onto manufacturers, marketplaces and developers and by vesting detailed rule‑making power in secondary legislation — a trade‑off that tight timelines and potential criminal penalties amplify, risking reduced competition, supply bottlenecks or slower adoption of micromobility and battery storage where compliance is costly.
The bill leans heavily on delegated powers: technical standards, the scope of prohibited listings, the nature of criminal offences and the contours of civil sanctions all arrive by regulation. That design preserves flexibility but also creates uncertainty for businesses that must plan compliance now without knowing the final requirements or penalties.
The use of terms like 'reasonable steps' for marketplace duties and reliance on CE/UKCA marking require regulators to define operational standards; enforcement outcomes will hinge on how strictly those phrases are interpreted and on the resources regulators receive.
Several practical tensions may complicate implementation. First, the CAB model presumes sufficient accredited testing capacity; if demand outstrips supply, certification delays could bottleneck legitimate products.
Second, the bill bars disposal regulations from imposing extra costs on local authorities, which constrains funding models for safe battery collection — implementing robust take‑back or collection schemes without council budgets may require industry funding mechanisms that the bill does not prescribe. Third, the devolved consent requirement creates the possibility of uneven application across the UK: the Act's safety protections could take effect in England sooner than in Scotland, Wales or Northern Ireland depending on devolved approvals, complicating cross‑border commerce and enforcement.
