We have over 700 IT companies in the Edinburgh and surrounding area (EH Post Code). 61% of the companies have less than 10 employees, and less than 7% have 100 employees or more. Around a third of companies work in the area of software development, slightly lower than in Cambridgeshires. The main sectors that companies supply their services too are IT, Financial Services and Healthcare. The Oil & Gas sector takes fourth place which is interesting, as the main Oil & Gas companies are located further north.
