Tower block fire highlights fire risk of plastic consumer units

10 February 2016


The safety risks associated with plastic consumer units have been highlighted by a fire in a ninth floor flat in Southampton. No one was injured but the flat was extensively damaged.

In order to cut the risk for fires and injury, the IET Wiring Regulations (BS 7671:2008+A3:2015), which the Institution of Engineering and Technology (IET) jointly publishes with BSI, has launched a new requirement for non-combustible (i.e. steel) consumer units. This new requirement (Regulation 421.1.201) came into effect on 1 January 2016.

The new regulation comes as the result of the IET’s work with London Fire Brigade, BEAMA and Electrical Safety First, which reported that a rising number of domestic house fires were being caused as the result of consumer units catching fire.

In fact, London Fire Brigade’s records show that there has been a five-fold rise in this type of fire in the last five years.

IET Chief Engineer, Geoff Cronshaw, said: “The IET Wiring Regulations set the standards for electrical installation in the UK and are used by many other countries, so they are regularly reviewed to ensure safety is top of the agenda.

“This new regulation, which requires consumer units in dwellings to be manufactured from a non-combustible material, such as steel, has the potential to save lives and cut the number of domestic fires in the UK.”

“The IET is concerned to hear reports that a nationwide housebuilder will still install plastic consumer units within new-build dwellings, despite the introduction of the new regulation. It believes that this may be the result of contracts that may have been agreed months or years ago and the building work would have been priced on the requirements at the time. However, it is drawing attention to the fact steel and plastic consumer units are very similar in price.”

Charlie Pugsley, Group Manager, Fire Investigation Team, London Fire Brigade, said: “Up to five London house fires a week are caused by consumer units and many of these could be avoided if the unit was cased in a metal or non combustible material. London Fire Brigade fully support the new amendment to the wiring regulations which will help stop fires spreading that start within the consumer unit."

Notes to editors:

  • Interview opportunities are available with IET spokespeople from a broad range of engineering and technology disciplines including cyber-security, energy, engineering skills, innovation, manufacturing, technology, transport and women in engineering.
  • The IET is one of the world’s largest engineering institutions with over 167,000 members in 127 countries. It is also the most interdisciplinary – to reflect the increasingly diverse nature of engineering in the 21st century. Energy, transport, manufacturing, information and communications, and the built environment: the IET covers them all.
  • The IET is working to engineer a better world by inspiring, informing and influencing our members, engineers and technicians, and all those who are touched by, or touch, the work of engineers.
  • We want to build the profile of engineering and change outdated perceptions about engineering in order to tackle the skills gap. This includes encouraging more women to become engineers and growing the number of engineering apprentices.
