The Sunday Times 100 features businesses from a wide range of sectors across the UK economy, highlighting companies that continue to drive innovation, create employment opportunities and deliver sustainable growth despite challenging market conditions. The Sunday Times mentioned that "the majority [of businesses] are based outside of the capital". They also point out that "a record number of companies were founded, co-founded or are led by women this year, a total of 33 per cent".

The Sunday Times described Wilson Power Solutions as follows: "This third-generation manufacturer began life in 1946, when its founder, Richard Wilson, started selling flameproof equipment, pumps and motors. Now it is led by his granddaughter Erika Wilson, 47, (an apprentice-turned managing director) and makes transformers — crucial components of the power grid that increase and decrease voltage. The Leeds-based company recorded sales of £113.6 million last year and has expanded overseas, with a factory in Chennai, India, and a power-hire venture in Dubai."

"To be recognised by The Sunday Times 100 for a second time is an honour. The standard for inclusion continues to rise, making this achievement even more meaningful. It reflects the dedication, expertise and hard work of every person across our business. Our people are the driving force behind our success, and I would like to thank them all for their contribution. For eight decades, hundreds if not thousands of customers have entrusted us with their business, and we are thankful for the longstanding trust that has supported our continued growth."
