Westminster Hall is an alternative Chamber for MPs to hold debates, named after the adjoining Westminster Hall.

Each debate is chaired by an MP from the Panel of Chairs, rather than the Speaker or Deputy Speaker. A Government Minister will give the final speech, and no votes may be called on the debate topic.

It is a pleasure, as ever, to serve under your chairmanship, Mrs Main, and to follow my hon. Friend the Member for Poplar and Limehouse (Jim Fitzpatrick) and the hon. Member for Southend West (Sir David Amess). As a member of the all-party fire safety rescue group, I identify entirely with everything they said, and without being boastful, we have made warnings that have not been heeded.

I want to concentrate on a particular area of concern, which is the safety of cables used in construction projects. I am indebted for what I am about to say to Tratos, a company that produces cables in my constituency. It has concerns about the way that the flammability of cables is classified in this country, and strong views about how that can be improved.

In July this year, a construction products regulation came into force, as a result of which all cables sold in the EU must now adhere to new, improved common standards. That should result in safer, consistent building regulations, and, as a consequence, improved public safety. The EU has not been prescriptive in specifying which classification of cable performance should be used for buildings and infrastructure. Instead, it is the responsibility of the regulator in each EU member state—which in this case is the Minister—to determine what that standard should be. I will advance the argument that the standard we are adopting is not good enough.

The Minister’s Department has not specified which class of cables should be used in buildings. Instead it requires all electrical installations in buildings to comply with British standard 7671—a minimum requirement that is equivalent to European class E. That allows more flammable cables that are less resistant to the spread of flames to be used in this country, and means that the UK is no closer to having a safer building environment for any buildings that use cables of that kind. Construction products regulation presents a real opportunity to ensure that the cables used in buildings and infrastructure are safe. Tratos has a manufacturing capability in my constituency, and it has declared that all CPR for fire cables should meet at least European class CCA, as that would ensure much greater safety.

I am sure that Members and the Minister will have seen images of cladding tests that show that the lower the classification, the quicker the fire spreads. There is a similar testing process for cables, which shows that the CCA category is much more resistant. The result is almost identical to that for cladding. The higher the specification for the cable, the less quickly the fire spreads.

The right hon. Gentleman raises an interesting point. Would he make that point about all white goods? My understanding is that it is primarily washing machines and tumble driers that are the first to go up, and that a higher percentage of them do so. Is he talking about all electrical goods, right down to washer-drier combos, microwaves and so on?

At the start of my remarks I identified entirely with the two previous speakers, and I wholeheartedly agree with everything that they said on that subject. I then said that I intended to speak specifically about cables used in buildings.

Tratos does not see the argument for introducing the CCA standard as if it were a sort of gold plating or a gold standard; it sees it simply as a good way of reducing the risk to public safety. It cites two reasons for that. First, it would ensure that regular plant auditing and regular audit testing of cables from the production line takes place. On a visit to the Tratos plant production facility in my constituency, I saw how rigorously it conducts its own testing. It also argues that if we introduce that standard, the reaction to fire would be better because there is no continuous flame spread, there is a limited fire growth rate because of the resistance to spread, and there is a limited heat release rate.

Tratos suggests—I wholeheartedly endorse this—that the UK regulator stipulate a minimum requirement of European class CCA for CPR. That is higher than at present, and will therefore provide better public safety. It also suggests a programme of market surveillance for CPR and cable compliance, to ensure that substandard cables are eradicated from the market. I understand that some countries produce inferior cable standard products, and export them to this country, where they are relabelled as meeting the British standards classification, although that does not by any means approach the European standard that we expect.

In the wake of Grenfell, it is timely to look at all aspects of regulation—white goods is clearly one of those, as is cladding and other factors in building, such as building layout and so on. All those things must be considered, and I argue that the standard of fire resistance for cables should be added to that list, because potentially, such cables could lead—I hope they do not—to another disaster on the scale of Grenfell.
