Building’s annual Top 150 Contractors & Housebuilders tables and analysis out on Friday

Overall revenue for the top 150 contractors and housebuilders rose by 6.4% year-on-year, according to Building’s annual Top 150 Contractors and Housebuilders list.

Our analysis of the most recent published accounts shows firms generated £113.5bn in revenue in total, £6.8bn more than the previous year.

This is a faster increase than the 2% rise seen in last year’s top 150, albeit from a slightly different group of companies. But it is down on the 9% seen two years ago. A total of 59 companies reported a drop in turnover, with 91 saying income had increased.

Our analysis shows contracting turnover among 87 firms rose by nearly £5bn to £57.5bn. This was a rise of 9% – slower growth than the 12% reported for last year.

Building will on Friday release its annual Top 150 Contractors & Housebuilders list. Our table enables you to sort the largest firms by a variety of metrics, including turnover, pre-tax profit, operating profit, margins and sectorr-specific revenue.

We will also be publishing separate lists for contractors, housebuilders and facillities management firms. We have dived into the data to uncover patterns lying in the figures and reveal which firms have had the biggest increases and falls in turnover, profit and margin. We will also publish an exclusive analyis of the housebuilding market.

Tomorrow (Thursday) we will publish a piece looking at overall sentiment in the contracting market.

However, housebuilding turnover rose more slowly than contracting income, increasing 5% among the top 50 housebuilders reflecting the continuing uncertainty of the market. It went up by more than £1.6bn to £35bn.

A total of 28 housebuilders reported a fall in turnover, with 10 of the top 20 reporting a drop.

Overall pre-tax profit decreased 5.2% from £4.1bn to £3.9bn – better than the 31% drop recorded by the previous year’s top 150. More than half – a total of 85 – reported profit increases, with 64 reporting drops.

Operating profit – which excludes certain one-off items and gives a better measure of underlying performance – increased by 4% to £4.7bn. On this measure, housing operating profit fell 12% but contractor profit rose by 55% to £1.3bn.
