Ashtead stands out because of its size. Its enterprise value - which aggregates the market value of a firm's equity (its market capitalisation) and the book value of debt, preference shares and minority interests - is over £12bn. By this measure it's a bigger company than Sainsbury's. It's four times bigger than Aggreko, the next biggest company in my list and more than ten times bigger than all the rest.

With revenues of nearly £3bn, Sunbelt - Ashtead's North American operation - is the second largest equipment rental firm in the USA. A-Plant, which earned £441m in the year to July 2017, is the largest hire firm in the UK.

Ashtead says its market share in both countries is 7%, which means it has lots of competitors. It may gain some advantage from its scale but no company dominates the industry and smaller companies may be strong in niches.

Andrews Sykes, a market leader in air conditioning and a good example of a niche business, may be of limited appeal to long-term investors though.

About 90% of the shares in Andrews Sykes are owned by a company affiliated to the chairman Jacques Murray and his family, or directly by the family. Although shareholders have prospered alongside the Murrays for over a decade, the fact that their stake is sufficient to carry any shareholder vote means they could, for example, vote to take the company private - bringing a buy and hold investment to a premature end. Other companies in the list have majority shareholders, but none have more than the 75% of shares required to pass a special resolution at a general meeting; the kind of resolution that might fundamentally change the status of a company.

You can find out who the major shareholders in any company are, and how many shares they own, in the DD view of SharePad, which also reports directors' dealings.

HSS and Arena only floated recently on the stock market, so we don't have enough data to examine their long-term track records. HSS's short-term track record is dismal, though, which has not done anything to change the dubious reputations of hire firms or new issues.

Northgate is also an anomaly. It doesn't hire tools and equipment; it hires vans. However it shares the same business model, and many of the same customers, especially in the construction sector.
