The 35,000 sq ft building, on Gelderd Road in Leeds, is due to open in June.

The business, which earlier this year launched a range of covid-safe welfare vehicles designed to ensure teams working on remote sites have access to a secure, virus-free environment, specialises in vehicle conversion and installation for firms with their own fleets. Vans and HGVs are equipped with features such as blind-spot camera systems and high-tech internal racking systems to make them safer and more efficient.

SM UK managing director Steve MacDonald, who founded the business in 2000, said: “We have continued to grow and to diversify the services we can offer our customers, and our HGV safety systems teams in particular have seen a rapid increase in demand.

“During the first lockdown it quickly became evident the transport industry would play a massive role in the pandemic and as a team we have been really proud to be on hand to support the fleets operating up and down the country.

“Many of our customers also operate in the construction industry, so as restrictions were eased, and more vans and HGVs returned to the roads, an increase in demand for our conversions and safety systems came with it.”

He added: “We’re now on the point of outgrowing our 10,000 sq ft Leeds facility, which we opened in 2018, and it’s exciting to be progressing the development of our new northern workshop and headquarters in the city, which will give us plenty of room to expand further.”

The business has acquired the 1.4 acre former Winerite warehouse site and work to redevelop the property as an auto-engineering workshop is currently underway.

SM UK, whose clients range from blue-chip companies with large fleets of HGVs, to individuals with a single van, currently employs 70 staff across its sites in Leeds and Tamworth.

The 30 new hires which will be for both engineering and office-based roles, will take the workforce to around 100.

Sales of the firm’s covid-safe welfare vehicles have grown rapidly and are expected to double the number initially forecast by the end of 2021.

“Everything we do is about making vehicles safer, both for drivers and for other road users and people working on sites,” said Mr MacDonald.

“Legislation such as Transport for London’s Direct Vision Standard has brought safety to the fore and prompted owners of commercial vehicles to ensure they have the relevant safety, lighting or racking systems installed on their fleet, and that is good news for everyone.”

The new Direct Vision Standard requires lorry drivers to prove they can adequately see potential hazards from their cab using specially installed cameras and other measures.

The new investment follows SM UK’s £3m investment in a new 13,000 sq ft vehicle conversion workshop in the Midlands.

Earlier this year, the firm also invested £200,000 to develop a fleet of Covid-safe vehicles designed to provide workers with a secure environment while working on remote sites. Each van is equipped with features such as sanitising stations, toilet facilities, a kitchen area and seating.
