The Impact of Firm Migration on the City of London
This project was commissioned by the City of London Corporation in June 2013. TBR was asked to examine the characteristics and trends exhibited by the business population within the City of London, also referred to as the ‘Square Mile’, and its surrounding areas, over the nine year period of 2003 to 2012, paying particular attention to firm migration. This period was one of significant change, including the deepest global recession since the 1930s. The research considers the impact, implications and interaction of firm migration on key aspects of the City including serviced premises, business clusters and the retail offer, as well as the adjacent ‘Tech City’ area.

This report provides a summary and overview of the research findings. The full technical report provides additional detail on each of these aspects and can be downloaded here1. This research brings together business performance data from TBR’s own database, Trends Central Resource (TCR)2 with property transactions data from Estates Gazette (EGi)3. The analysis of business migration represents a novel approach to investigating this underresearched component of economic change. When combined with the other components of start-ups, closures and continuing firms, the research provides new insights into the forces at play within a local economy.

RESEARCH REPORT CITY OF LONDON CORPORATION
Summary findings The City is a global centre for finance and a key driver of wealth creation in the UK. Given the nature of the 2008 recession (balance sheet rather than inflationary), the City, along with London and the UK as a whole, was inevitably exposed to its full consequences. Since then, the UK economy has made a slow recovery and has yet to recover to pre-recession levels of Gross Domestic Product (GDP) output.
At present, the City is home to 17,750 businesses employing 365,500 people that contribute over £38.5bn to the UK economy5. Furthermore, the City is highly productive (£105k output per employee) compared to London (£57k) and the UK (£38k). Figures 1, 2 and 3 demonstrate that while businesses in the City represent only 4% of London’s total firms, they are highly productive, generating 8% of the employment and 16% of the output.
By comparison, the City has recovered relatively well. Following initial reductions in firms, employment and output4, the latter is now above the 2008 level, though firm and employment numbers are still to match their earlier peaks.

The Impact of Firm Migration on the City of London
How is the profile of the City’s business community being changed by migration? The components of change that impact any economy comprise of the following: 1. Business start-ups and business closures; 2. The performance of continuing businesses (i.e. businesses that survive the period of time); andEmployees 365,500 3. Inward8% and outward migration of businesses. This research investigates the effects of these three components of change over a nine year period, 2003 to 2012. Each of these three components is investigated in more detail in the following sections.
Reading from left to right, Figure 4 describes the position in 2008 (Stock 2008) in terms of the number of firms, people employed and amount of output (as defined by Gross Value Added), followed by the impact of firm births (Births 2008 to 2012), continuing firms (Continuing Businesses) and closures (Deaths 2008 to 2012) to present the position in 2012 (Stock 2012). The vertical axis highlights the impact of firm migration into and out of the City. Stock 2008 + Births + Continuing Businesses – Deaths + In Migrators – Out Migrators = Stock 2012
Figure 4 sets out a detailed analysis of these three components over a more recent time period in particular, 2008 to 2012, to provide an overview looking forward (post-recession).

RESEARCH REPORT CITY OF LONDON CORPORATION
Business start-ups and business closures Over the period 2003 to 2012 there were over 1,000 start-ups annually (12,000 in total). By 2012, 27% of all firms in the City had been set up within the last four years, i.e. since 2008. This compares to 31% for London as a whole over the same period.
As a result, employment losses through closures have tended to exceed those gained from startups. Thus for every three employees lost through business closures, only two are replaced by new business starts.
By contrast, business closures have ranged between 1,000 and 2,000 per annum since 2008. This generated a closure rate of 44%, which is comparable to London. However, this is notably higher than the start-up rate of 27% for the same period in the City.
The net effect of business start-ups and closures was a reduction of ÂŁ3.9bn in output and nearly 33,000 jobs over the period 2003 to 2012.
As Figure 5 shows, the rate of firm closures continues to outpace start-ups, suggesting that recovery is still fragile.

Overall, migration can be seen as having extremely positive impacts for the City economy.

These strong economic contributions are in part 100 to increases in productivity. Average output due per50employee in serviced premises has risen from £60k to £94k over the last nine years, indicating an 0 influx of highly productive businesses.
2004-05
1. Inward migrators are generally larger (33 employees) than outward migrators (24). 2. I nward migrators are more productive, generating £113k per employee than outward migrators (£67k). 3. Inward migrators are more established, typically between 10 and 20 years old compared to outward migrators that tend to be nine years old or less. 4. Inward migrators are more likely to be European or North American-owned, whereas outward migrators are more likely to be independently owned.

The number of businesses in serviced premises has risen significantly over the last decade. The number of tenants in a sample of serviced premises in the City and surrounding areas, increased from nearly 700 in 2003, to almost 2,400 firms in 2012 (see Figure 8). Coupled with this are steady rises in employment from a total of 8,800 employees in 2003 to over 22,000 in 2012 in 300 serviced premises in the City (or 10% per annum), 250 a fourfold increase in economic output from and £523m to over £2.1bn (or 15% per annum). 200

Firms tend to relocate from or to other parts of London, with adjacent boroughs featuring most prominently. While Westminster usually provides the greatest number of inward migrating firms, the majority of employees come from firms relocating from Islington. The South East of England is the most popular location outside London.

The Impact of Firm Migration on the City of London
What type of office space is attractive to businesses, especially those that have moved into the City? Most prevalent sectors located in serviced premises n Professional, Scientific & Technical – 580 firms. n Real Estate & Administrative – 460 firms. n Information & Communication – 330 firms.
Other characteristics of businesses located in serviced premises n Most firms less than five years old. n Few firms over 15 years old. n Firms have an average productivity rate of £94k per employee, above the London average of £57k per employee.
The average size of office space taken up in the City is 6,400ft2. By comparison, inward migrants tend to take up significantly larger premises, of around 8,830ft2 on average. The average cost of office space taken up in the City was £27 per ft2 whereas inward migrants tend to pay slightly more at £31 per ft2 (see Figure 9).
Key characteristics of premises Inward migrators tend to pick newer buildings constructed from the 1990s onwards, compared to businesses in general that are more likely to choose pre-war buildings or those built between the 1950s and 1970s. Inward migrators are more likely to select second-hand grade A office space, compared to businesses in general, which are more likely to select second-hand grade B office space.

What is the impact of Tech City? What type of businesses move to it? For the purposes of this report Tech City has been defined as a geographical location to the north of the Square Mile, and includes an element of overlap with the City. It is comparable to the City itself in terms of the business base, though Tech City has a slightly greater number of businesses within its area than the City – 21,100 actively trading businesses in 2012 (compared to 17,750 in the City). However, Tech City businesses are generally smaller, employing a total of 243,600 people (versus 365,500 in the City) and less productive than the City, outputting £17.4bn to the UK economy (or £71k per employee, compared to £105k in the City). This difference in productivity largely reflects the Square Mile’s position as a global leader in finance and Tech City’s greater reliance on (relatively new) tech firms.

Across Tech City start-ups have exceeded closures over the whole nine year period (2003 to 2012). However, in 2008/09 the situation reversed, with more closures than starts. Similarly in 2011/12; this downward trend is particularly noticeable and results mainly from a dramatic fall in the number of start-ups, though the rate of closures has also risen. 350
The analysis of start-ups and closures suggests that 300firms are surprisingly similar in size, output and these productivity. It would be anticipated that new firms250 would be smaller and less productive than those that close. 200

TMT performance in Tech City The Technology. Media & Telecommunications (TMT) sector has fared relatively well in Tech City: n There were marginally more start-ups than closures over the four year period 2008 to 2012 in particular, when Tech City as a whole saw net closures. n While there were around a fifth fewer inward migrators than outward migrators, incoming firms were slightly larger (12 employees compared to 11) and significantly more productive (£109k per employee compared to £81k per employee). n Continuing firms also generated an extra 130 jobs and raised output by £168m.
Destinations of outward migrators
Characteristics of businesses that move from Tech City to the City 1. Micro businesses, with 10 or fewer employees. 2. H ighly productive businesses, with an average of £108k output per employee. 3. M ainly office-based, working in the Financial Services, Real Estate or Professional, Scientific & Technical Services sectors. 4. Mainly independently or UK-owned. Overall then: n Since 2008 Tech City as a whole has been losing firms, and experienced reduced levels of employment and output as a result of net outward migration. n T here is a greater preponderance of TMT businesses in Tech City than in the Square Mile. n Since 2008 the TMT sector bucked the trend and generated more start-ups than closures, which contributed to the overall firm base.
The City, Westminster and Camden were the main destinations for firms moving out of Tech City. However, the nature of the Tech City geography may mean that firms that moved premises from one part of Islington to another may be classified as outward migrators even though they have stayed within the borough.

There is an above average density of businesses and employment in the areas surrounding the City but at a significantly lower level than within the Square Mile. The density of Financial Services businesses has decreased between 2003 and 2012 both in the City and adjacent areas, suggesting either a reversal in the trend towards co-location, or that mergers have consolidated the number of businesses.

Professional Services In 2012, the Professional Services cluster in the City had 3,780 firms with 79,800 employees that produced £8.1bn in output. The cluster has proved resilient over 2003 to 2012. There is a prevalence of businesses in the west of the City7, forming part of a larger cluster of activity connecting the City with Camden, Westminster and Islington. Clusters in the centre and the east of the City have seen reductions in employment density, but not firm density, suggesting firms in the centre and east have reduced headcount over time.

To retail within the City in more detail, TBR developed the Retail Variety Index (RVI). The RVI is an indexed score that takes into account: the variety of retail activity, the degree of monopolisation, the geographic density of retail and the level of retail independence. Generally the higher the score the better the retail 150 offer. Output
These firms produced £820m in economic output (2% of the City’s total), at a rate of £36k per employee.Firms This level of productivity is much higher 25,800 1400 than the retail offer in the rest of London (£30k) Employment 25,600 1200 and the UK (£23k) but significantly lower than 25,400 the City’s overall average of £105k.

Concluding remarks About the economy
About property demands
The migration of businesses is an area of economics that is particularly underresearched. However, it is clear from this research that firm migration has played a vital role in the City’s economic revival following the recession.
While the property market has always had to respond to the demand for premises from firms that start, grow and shrink – be they already in the City or moving in – there has been little empirical evidence of the relevant proportions and their respective requirements. This research demonstrates that there are discernible differences between groups of businesses.
The gains from firm movements have largely overcome the net decline attributable to closures and start-ups. Post 2008, migration has been more prevalent, with increased flows of businesses into and out of the City. Should this increased propensity for businesses to migrate continue, it should prove positive for the City. Not only will it mean an increase in firms, employment and output, it is also likely to contribute towards the diversification of the City’s economy, in addition to the traditional dominance of Financial Services and Insurance firms.
Serviced premises are clearly important and provide a vital component of the overall offer, especially for new and small firms. Likewise second hand Grade A and, to a lesser extent, Grade B premises are also in demand for businesses seeking their own premises in the City.
