UK Parliament Warns Forensic Science Crisis Remains Unresolved as 20,000 Devices Await Analysis

A new UK parliamentary briefing has renewed concerns about the condition of forensic science services in England and Wales, highlighting a backlog of more than 20,000 digital devices awaiting examination and unresolved questions about the independence of forensic evidence.

Published by the House of Lords Library on November 5, 2026, the briefing examines the government's response to a parliamentary committee report that warned of serious weaknesses across the forensic science system.

The briefing comes ahead of a House of Lords debate scheduled for November 11, when lawmakers are expected to consider recommendations for rebuilding forensic science services.

One of the most pressing problems concerns digital evidence.

Police investigators increasingly rely on information recovered from smartphones, computers, and other electronic devices. However, growing evidence volumes and limited examination capacity have created substantial backlogs.

A government policing reform document previously estimated that approximately 20,000 devices were awaiting forensic analysis at any given time.

In a parliamentary response dated October 20, policing minister Sarah Jones acknowledged that digital forensic backlogs remained a significant challenge.

The Home Office also confirmed that it did not hold the requested national figures for average examination waiting times or the number of criminal cases delayed by digital forensic processing.

This creates an important accountability problem.

Without consistent information about processing times and affected investigations, assessing whether reforms are improving forensic capacity becomes difficult.

The concerns extend beyond digital evidence.

A February report by the House of Lords Science and Technology Committee identified weaknesses in the commercial forensic science market, inconsistent oversight of police-operated laboratories, and problems with long-term evidence storage.

The committee reported that one company, Eurofins, provided more than 80% of external forensic science services, raising concerns about market concentration.

It recommended establishing an independent National Institute for Forensic Science to strengthen scientific standards, research, and oversight.

The government declined to adopt that central recommendation, instead proposing a nationally coordinated forensic service within its planned National Police Service.

According to the November briefing, the government had not yet provided a specific progress update on establishing the proposed national service.

Forensic independence remains a particularly important concern.

Scientific evidence must be evaluated objectively, regardless of whether its findings support the prosecution or defence.

The committee warned that forensic services operating too closely within police structures could create risks involving oversight, consistency, and unconscious bias.

For investigators, the backlog also has practical consequences. Delayed examinations can postpone access to potentially important evidence, while long-term storage and rapidly changing technology create additional challenges.

However, the available figures do not establish how many individual prosecutions have been delayed or how much time each examination requires.

The November 11 parliamentary debate will provide another opportunity to scrutinise the government's approach.

The briefing highlights a broader question facing forensic science in England and Wales: whether structural reform can improve examination capacity while preserving scientific independence, quality, and public confidence.
