The property market in the UK has been buoyant in recent years leading to generally positive financial results for the major residential and commercial property services groups.

The past 24 months has borne witness to the rise of what has been coined as “PropTech” – businesses which operate in or around these businesses’ value chains but use technology to challenge incumbent businesses or solve consumer problems that incumbent businesses have not tackled.

Incumbent businesses in the sector, enjoying good trading conditions, have yet to act in response to the threat posed by these new entrants.

The most widely discussed threat is that posed by so called “online” estate agents – businesses that claim to use technology to provide customers with a low cost alternative to typical estate agents. However, startups have sprung up across residential, commercial and other parts of the property ecosystem and they are determined to change the status quo.

The burgeoning PropTech space is focused on London. The city has recently come to be seen as a leading location to establish such businesses as part of a wider strategy to attract technology businesses across all sectors. Significant money is now being deployed in PropTech as can be seen in recent investments raised by, in particular, the online estate agents.

There has been a flurry of small investments in PropTech businesses led by Pi Labs and Seedcamp, which has made 13 investments in Prop:Tech businesses to date. There is also some public awareness of the potential for the sector as evidenced by some successful crowd funding campaigns by online estate agents.

It has been demonstrated across multiple sectors – including property – that consumers are inclined to use technology solutions that address their needs or wants, usually at a lower cost than incumbent solutions. This can be seen very clearly in the search part of the customer’s journey through the residential property transaction value chain.

Consumers are very happy with only two service providers – Rightmove and Zoopla. These businesses have created in effect a monopoly position and generate supernormal profits as a result. This has been to the detriment of the incumbent in that space, namely traditional print media.

It is entirely likely that property services businesses will come under threat from new entrants that have the potential to create similar monopoly positions at all points of their businesses in the next few years and therefore it is entirely sensible for those firms to consider a defensive, yet proactive strategy.

The first firm to act in this sphere will either prevent competitors from acquiring or investing in the best businesses or, if they do invest later, they will have to do so at much higher valuations. Either way, this creates competitive advantage for the first mover.

The market today is accessible for a strategic investor. Although some significant money has entered the PropTech vertical, it has focused primarily on online estate agencies, driving valuations much higher in that specific market than in others.

However, although those businesses have high valuations, they do not have large cash piles. Instead, they are reliant on regular and further fundraising rounds to grow their brands and their technology. This means that they are not in a position to acquire competitors or complementary businesses – yet.

There are two key things on which an incumbent property services firm must keep a wary eye if considering investing.

Firstly, many of these businesses are very narrowly niched and have not generated any traction yet.

Secondly, their business models may not be designed to work in concert with incumbents which may make it very difficult to generate traction in future.

Institutional money has not yet been deployed in this sector to any meaningful level but, when it comes, valuations will soar even higher, making it very expensive to enter the market in as little as six months’ time.

Incumbent property services groups have a chance to act now. Failure to do so will be extremely costly because as soon as a PropTech startup finds itself sitting on a cash pile due to investment or IPO it will go on an acquisition spree, locking incumbents out of the market and sealing their slow and painful death.
