PropTech is one of the most exciting parts of the modern UK economy. It’s where real estate, data, software and automation collide. It covers everything from AI driven valuation tools to energy optimisation systems inside smart buildings. If it touches how we build, operate, manage, or invest in property, it sits somewhere inside this sector.
Why does it matter? Because the built environment drives productivity, net zero progress, housing affordability, and the UK’s ability to attract investment. PropTech is where many of the solutions to these challenges are being built. The sector is expanding fast, and until now it has been difficult to see it clearly. Traditional SIC codes bury it under labels like “management consultancy” or “other service activities”, obscuring the real story.
At The Data City, we classify companies in real time using website text and machine learning. Our Real Time Industrial Classifications (RTICs) give a clear picture of what PropTech looks like today, not what it looked like in 2007.
We’ve recently launched our ALPHA PropTech RTIC, which maps the UK’s PropTech landscape. You can learn more about what an ALPHA RTIC is in our blog to Introducing alpha RTICs
Let’s bring the fog down and show you the sector as it really is.
The PropTech RTIC: four core verticals
We classify the sector into four key verticals:
- Construction and development – Tech that supports planning, design and delivery of real estate and infrastructure.
- Property management and leasing – Software and platforms that streamline buying, selling, letting and property operations.
- Real estate investment tech – Tools for analysing property markets, valuing assets and supporting investment decisions.
- Smart buildings and IoT – Connected systems that enhance sustainability, energy efficiency and occupant experience.
Now the scene is set, let’s look at the companies reshaping the sector.

What this tells us about the UK PropTech sector
This ranking makes one thing clear. PropTech is no longer just a support function. It is a high growth, high skill, high complexity part of the UK economy, with clusters in:
- London
- The Northeast
- Sheffield
- The Southeast
The sector includes everything from low carbon retrofitting to AI powered valuations. Yet SIC codes hide most of it. PropTech companies commonly sit in unrelated SIC labels including:
- Management consultancy
- Electrical installation
- Other information service activities
- Activities of head offices
- Architectural activities
This is why accurate, real time classification matters. You cannot build policy, investment strategies or innovation support on broken foundations.
Looking ahead
PropTech is evolving at speed. Energy optimisation, automation, IoT integration and AI driven investment insight are becoming standard. The companies above prove that the next generation of the built environment is already here.
