Upcoming 2023 IPOs in the UK

Tracking the UK Contech Market | 2022

Farzana Haque, 08 December 2022

Contech (construction technology) has arrived to revolutionise the traditional construction industry. Indeed, construction companies already recognise the benefits of this emerging market, with several large acquisitions of contech startups taking place in recent years, such as American construction heavyweight Trimble buying Viewpoint in 2018, for $1.20b. 

Here in the UK, the construction sector provides an excellent opportunity for innovative technologies to support the transition to net zero. The UK Government has pledged to move towards cleaner growth measures, such as halving the energy use of new buildings by 2030. Its 2019 Construction Sector Deal paper outlines key policies, such as a commitment to invest £725m into programmes that capture the value of innovation. This sets the perfect stage for contech startups to grow in the UK. 

In this piece, we explore the UK construction technology sector in detail and profile 10 top high-growth contech companies, based on the amount of equity investment they’ve raised to date.

What is contech?

Contech refers to the use of innovative technologies in construction, often in the early stages, ranging from design to building materials and civil engineering. 

Is contech the same as proptech?

Proptech (property technology) focuses on property sales and post-construction matters, such as maintenance. Whilst there are certainly overlaps between the two, contech is a separate industry of its own. A notable difference between contech and proptech is the addressable market for the respective sectors: contech addresses multiple asset classes, including infrastructure, industrial, commercial and residential, while proptech only applies to commercial and residential. 

Uses of construction technology

There’s a diverse range of technologies emerging within contech. For example, in communications, software and mobile apps are being developed to collect, store and share documents for construction projects. There are also wearable technologies that can improve workplace safety, such as smart watches which detect slips, trips and falls and automatically contact help in an emergency. 

Another technology widely employed by contech companies is predictive analytics, which uses historical data to identify and mitigate risks. Meanwhile, contech also refers to 3D printing and immersive technologies, like augmented and virtual reality, in modelling sites. Extended reality technology offers a range of solutions, bringing designs to life to help visualise blueprints.

Trends in the UK’s contech sector

There are 46 high-growth contech companies in the UK, employing around 2k people. A large proportion (44%) are currently operating at the seed stage of evolution. This is similar to other startup sectors, such as fintech, where 43% of high-growth companies are in the seed stage: startups in their early days, operating with a low employee count and little to no equity investment. In contrast, just 15% of contech businesses are operating at the established stage.

In line with traditional construction, contech seems to be a very male-dominated sector, with 95% of contech company founders identifying as men, where gender is known, and 90% of companies having all-male founding teams. This is significantly worse than the UK’s wider high-growth ecosystem of 45k+ companies, in which 75% have all-male founding teams. 

The breakdown for the companies in this article is slightly better, but still leaves considerable room for improvement, with 63% being founded by all-male teams. As the sector continues to gain momentum and investor interest, we hope to see more female entrepreneurs emerging in this space in the coming years.
