GSK’s announcement that it will close its Stevenage research and development site by 2029, relocating around 1,000 employees to a new £400 million facility on the Cambridge Biomedical Campus, marks the end of an era for one of the town’s most recognisable employers.
The company has been part of Stevenage for more than 50 years, so it’s understandable that the news has raised questions from homeowners, landlords and local businesses alike.
As estate agents and letting agents in Stevenage, one question has come up repeatedly since the announcement.
Will this affect the local property market?
The short answer is probably not in the way many people might expect.
A phased move, not an overnight departure
One of the most important details is that GSK isn’t closing tomorrow. The company plans to relocate staff in phases over the next three years, with the Stevenage site remaining operational until 2029.
That gives employees, homeowners, landlords and businesses time to adapt.
It’s also worth remembering that GSK isn’t leaving Hertfordshire altogether. Alongside the Cambridge investment, the company has confirmed further investment into its research facilities in Ware, with some employees expected to relocate there instead.
What could it mean for Stevenage house prices?
Whenever a major employer announces a move, concerns about house prices naturally follow.
However, today’s Stevenage is a very different town from the one GSK first moved into half a century ago.
The town now benefits from a diverse employment base including advanced manufacturing, aerospace, engineering, logistics, technology, life sciences, financial services and London commuters.
According to the latest Office for National Statistics figures, the average house price in Stevenage reached approximately £318,000 in May 2026, representing annual growth of around 4.3%. Average private rents have also continued to increase, reflecting the strong demand for homes across the town.
While GSK’s announcement is significant, house prices are influenced by many factors including interest rates, housing supply, affordability, buyer confidence and the wider economy. One employer, even one as important as GSK, is unlikely to determine the direction of the entire Stevenage property market.
Will landlords be affected?
For landlords and buy to let investors, this announcement should be viewed with perspective rather than panic.
As specialists in property management in Stevenage, we continue to see strong demand from professionals working across Hertfordshire, London and Cambridge. Stevenage remains one of the region’s best connected commuter towns, with fast rail services into London King’s Cross and improving connections towards Cambridge.
Some GSK employees may choose to relocate closer to Cambridge over the coming years, but many are also likely to remain in Stevenage, where housing remains considerably more affordable than Cambridge itself.
Demand for quality rental properties continues to outweigh supply across much of the local market, particularly for homes close to the station, Stevenage Old Town and major employment hubs.
Cambridge may benefit, but Stevenage still offers value
There is little doubt that Cambridge will attract more life sciences professionals as GSK joins one of Europe’s leading research clusters.
However, Cambridge is already one of the UK’s most expensive places to buy or rent a home.
For many employees, remaining in Stevenage while commuting may prove to be the more practical and affordable option, particularly with improved transport links between the two cities.
An opportunity for Stevenage
Although losing such a well known employer is disappointing, it also creates opportunities.
The GSK site occupies a prime location and represents one of the largest redevelopment opportunities in the area. With Stevenage continuing to attract investment across science, technology, engineering and advanced manufacturing, there will almost certainly be significant interest in the site once it becomes available.
The challenge for local leaders will be ensuring the next chapter is every bit as successful as the last.
Why local property advice matters
National headlines often paint a dramatic picture, but property markets are driven by dozens of local factors.
As estate agents in Stevenage and letting agents in Stevenage, we speak with buyers, sellers, landlords and tenants every single day. That gives us a far clearer understanding of market sentiment than national speculation ever can.
Stevenage remains one of Hertfordshire’s strongest commuter locations, offering excellent value compared with neighbouring towns and cities, outstanding transport links and a broad employment base that continues to attract buyers and tenants alike.
Our view
GSK’s decision is undoubtedly significant for Stevenage and for the many families connected to the company. However, we don’t believe it fundamentally changes the long term outlook for the local property market.
Markets evolve, businesses relocate and economies change, but the fundamentals that make Stevenage an attractive place to live remain firmly in place. Excellent transport links, strong housing demand, continued investment and a diverse local economy continue to underpin confidence in the area.
While GSK’s departure marks the end of an important chapter, we believe Stevenage’s story is far from over. The town has consistently shown its ability to adapt and evolve, and from a property perspective we remain confident that it will continue to be one of Hertfordshire’s strongest locations for homeowners, landlords and investors alike.
