So what can be done to reduce the talent shortfall?
Provision of appropriate space
Developers need to ensure that the appropriate sort of space is being provided to develop talent. Partly funded by Scottish Enterprise, Scotland currently provides more incubators (2.5) and accelerators (5.8) per 1,000 new businesses than all other UK regions, providing a platform for business growth.
However, all other UK regions provide fewer accelerators per 1,000 businesses than London. Accelerators base their business model on equity from startups, with a strong emphasis on growth over a fixed duration programme, usually around six months. In order to retain homegrown companies who are looking to scale up, the regional cities must increase accelerator provision.
What's more, part of the reason for the shortfall in floorspace is that high-growth companies are offered favourable rents and are not moved on to conventional office space quickly enough. If existing start-ups were offered subsidised rents in the first and second years, leading to harder commercial terms in subsequent years, this would free up more space for incomers.
Improving labour mobility
Mobility of labour remains one of the major labour markets constraints within the UK. Compared with other European countries, workers are considerably less footloose, which can be partially accounted for by increasing house price disparities between London and the UK regions.
Savills What Workers Want survey indicates that workers wanted to change the length of commute to work more than any other factor. Proximity to the workplace is what workers are most concerned about, and investing in infrastructure projects in the regional cities, from HS2 to local bus routes will help improve regional labour mobility and attract talent away from London and the South East.
Employees' perspective
With significantly higher living costs for workers relocating into the capital, the northshoring argument is becoming even more compelling for employees.
The first time buyer house price to earnings ratio in London now stands at 10.2, almost twice the national average, according to Nationwide. With an increasing disparity between the most expensive and least expensive UK regions, many workers in London are resigned to the fact that home ownership is becoming a pipedream. Burberry plans to relocate finance, HR, IT and procurement to Leeds, where the first time buyer house price to earnings ratio is 3.7. If one of workers' key priorities is "climbing the housing ladder", it is no wonder that anxiety levels are significantly higher in the capital than in the rest of UK regions, according to ONS figures (Graph 4).
We expect the net inflow of graduates to London to ease off as regional infrastructure projects are delivered and workers take advantage of higher living standards by working and living in the regions.
