INVESTIGATION and INQUEST

On 13/12/2023 I opened an inquest into the death of Mohsin Janjua who, at the date of his
death was aged 28 years old. The inquest was resumed and concluded on 30/07/2025.

I found that the cause of death to be: -
1a The Effects of Fire

I concluded with a narrative conclusion:
On 02/12/2023, Mohsin Janjua died from the inhalation of products of combustion in a
house fire at his home address at
, Bradford. Unknown to him, he had
previously purchased an unsafe lithium battery on the internet in order to convert his
bicycle with other modifiable parts to an E-bike, which he left on charge overnight in his
living room. It is found more likely than not that the fire was caused by a catastrophic
failure of the ion lithium battery.

CIRCUMSTANCES OF THE DEATH

During the early hours of 02/12/2023, whilst the family were asleep at their home address
of
, Bradford a pedal cycle converted by Mohsin to an e-bike suddenly caught
fire after he had plugged its battery into the mains in the living room where he was
sleeping on the sofa.

When Mohsin became aware he immediately alerted his mother and son in the upstairs
bedroom and they were all able to exit by way of the front door. However since Mohsin’s
brother was thought to be trapped inside the house, Mohsin re entered the burning
property in a bid to locate him, albeit in doing so he was unaware that his brother had
previously jumped to safety from his upstairs bedroom window, sustain injuries in the
process.

Notwithstanding his injuries, Mohsins brother made his own desperate attempt to re enter
the property, risking his own life, but despite his best efforts, was forced back by the
density of the toxic smoke and fire intensity to escape down the stairs.

Upon the arrival of fire service and upon entering the property, Mohsin was found
unresponsive in the rear upstairs bedroom, but was subsequently found to have died.

The inquest heard that Mohsin had converted his Carrera bike with an electric motor 18

 months previously and that he had replaced the motor a week before he died with a
20am/hour 52-volt battery.

Test purchases were conducted after it was established that he had purchased the battery
from a site on eBay and a forensic examination of this along with the recovered remains of
the lithium battery from the fire.
The test purchase battery and charger, thought to have emanated from China, were found
not to confirm with UK safety standards and regulations. Although the battery recovered
from the fire showed some similarities with the test purchase, the extent of its fire damage
prevented further identifications.

The fire investigation officer confirmed in his evidence that the ion-lithium battery
purchased by Mohsin was the source of the fire.

CORONER’S CONCERNS

During the course of the investigation my inquiries revealed matters giving rise to concern.
In my opinion there is a risk that future deaths could occur unless action is taken. In the
circumstances it is my statutory duty to report to you.

The MATTERS OF CONCERN are as follows:
(brief summary of matters of concern)

• To review and reconsider the adequacy of the of the current unregulated sale of lithium-
ion batteries, especially those intended for e-bike conversions through online market
places, since they pose a significant and growing risk to public safety.
• Fires caused by substandard or non-compliant batteries have increased and many
originate from online marketplaces.
• At the moment it is my understanding that online market places disclaim responsibility for
the safety of 3rd party goods, so I ask that you give consideration to the appropriateness of
regulations to make online marketplaces jointly responsible for ensuring the safety and
legal compliances of products sold on their sites.
• Consider further steps to increase the general publics awareness with regard to the life
threatening risks involved with lithium ion batteries from e-bikes in this case stored in
domestic properties.

ACTION SHOULD BE TAKEN

In my opinion action should be taken to prevent future deaths and I believe you (and/or
your organisation) have the power to take such action.

Dear Mr Fleming, 

Thank you for sharing your Regulation 28 Report to Prevent Future Deaths, dated 5 
August 2025, concerning the death of Mohsin Janjua following a house fire started 
by an e-bike battery. I am responding in my role as Chief Executive of the Office for 
Product Safety and Standards (OPSS), which is part of the Department for Business 
and Trade.  

I was sorry to hear of Mr Janjua’s death. In my letter to you of 31 May 2024 I set out 
some of the actions OPSS were taking at that time. I am grateful for the opportunity 
to outline the further actions we have been taking since.    

Regulatory framework 
The safety of e-bikes and their batteries is a high priority for Ministers and for OPSS. 
Lithium-ion batteries for e-bikes and conversion kits are regulated under the General 
Product Safety Regulations 2005 (GPSR). This places obligations on those 
producing or importing consumer products, including lithium-ion batteries, to ensure 
their products are safe before being placed on the market, whether sold online or in 
physical retailers. Distributors also have duties regarding product safety under 
GPSR. OPSS and Local Authority Trading Standards departments have powers to 
take action when non-compliant or unsafe products are identified, including removing 
them from sale.  

While product safety regulations do already apply to online marketplaces when they 
are carrying out the activities of a distributor, we recognise that the growth of e-
commerce has created challenges for the product safety framework. The 
Government recently introduced the Product Regulation and Metrology Act 2025, 
which received Royal Assent in July 2025. The Act enables Government to introduce 
new duties on online marketplaces with regards to product safety. TGovernment has 
committed to consult on these responsibilities at the earliest opportunity, to create a 
proportionate regulatory framework where online marketplaces prevent non-
compliant and unsafe products being made available on their platforms.  

The Office for Product Safety and Standards (OPSS) delivers consumer protection and supports business 
confidence, productivity and growth. It is part of the Department for Business and Trade.

In December 2024 the Department introduced statutory guidelines for the safety of 
lithium-ion batteries supplied for use with e-bikes. These guidelines apply to all 
lithium-ion batteries for e-bikes, including those sold online or sold for use with a 
conversion kit. They set out what is required for these batteries to be considered a 
safe product under GPSR, including that they must have a mechanism, or 
mechanisms, to protect against the risk of thermal runaway, which is a major cause 
of battery fires. We expect product distributors, including online marketplaces acting 
as distributors, to take account of the guidelines in assuring themselves that the 
product is compliant and meets the requirements of GPSR before making a lithium-
ion battery available on the market. OPSS senior leaders regularly meet with the 
major online marketplaces operating in the UK market to hold them to account for 
their product safety responsibilities, including implementing these guidelines. 

We are also working with businesses and other stakeholders to improve technical 
understanding of producing safer e-bike batteries. We have commissioned the 
British Standards Institution (BSI) to produce a fast-track standard – known as a 
publicly available specification (PAS) – on technical requirements for battery systems 
used in e-bikes, e-scooters and conversion kits. The PAS will be informed by a 
significant research project we commissioned from Warwick Manufacturing Group on 
lithium-ion battery safety, which was published in January 2025 on gov.uk. 
Businesses will be able to follow the recommendations in this PAS to help 
demonstrate their products comply with product safety regulations. The development 
of the PAS is being led by a technical expert steering group, including 
representatives from industry and academia. We anticipate it will be published by 
BSI in 2026.     

Enforcement Action  

OPSS’ investigation into the safety of the lithium-ion battery involved in the fire which 
led to Mr Janjua’s death, and another serious fire in the West Midlands, identified the 
specific models of UPP battery involved. The evidence enabled OPSS to take 
enforcement action in January 2024 to prohibit the sale of these battery models in 
the UK, which included their supply by online marketplaces. 26 Withdrawal Notices 
were served on eight online marketplaces, two manufacturers and 16 other sellers, 
requiring them to immediately stop the supply of two dangerous models of UPP 
battery. OPSS also published public safety messages advising consumers not to use 
the models and how to dispose of them safely.  

The Office for Product Safety and Standards (OPSS) delivers consumer protection and supports business 
confidence, productivity and growth. It is part of the Department for Business and Trade.

The prohibition on supply of these dangerous batteries remains in place. Should 
regulators become aware the models are available in the UK, action will be taken to 
remove them from the market.  

Public awareness 

In 2024 the Government’s safety campaign ‘Buy Safe, Be Safe’ was launched, 
aimed at raising public awareness of the risks from dangerous e-bikes, e-scooters 
and their components with advice on safer purchasing and charging practices. OPSS 
is working closely with other Government departments, as well as safety charities 
Electrical Safety First and the Royal Society for the Prevention of Accidents, local 
authorities, fire and rescue services, and retailers, to amplify these important safety 
messages through their networks and communication channels.  

OPSS has also produced Buy Safe, Be Safe videos with five key safety steps that 
users should take if they own or use e-bikes. These videos have been translated into 
several languages. They are aimed particularly at food delivery riders, based on 
insights from gig economy companies. OPSS has shared the videos with those 
companies and encouraged them to raise awareness with riders and couriers.    

While I believe that the actions outlined above will make a material difference to 
consumer safety in this area, e-bike safety, and the sale of unsafe products via 
online marketplaces, remains a priority area for OPSS.   

Thank you again for raising these important issues. I would be grateful if you could 
share a copy of this letter with colleagues who may find it useful. 

Kind regards, 

Chief Executive
