What makes a city good for business? Employers usually list a skilled workforce, good transport links, low property costs and good communications networks as top priorities. (46) As computer and telephone networks become increasingly sophisticated, businesses no longer have to be tied to one place or run all their operations on one site. Most of the country now has access to broadband. Insurance giant Norwich Union is one company which now operates from 1,200 sites nationwide, all linked up through a single network. (47) Call centres can operate as easily from Liverpool as from London and employees can be scattered across the country, working from home and keeping in touch with the office via e-mail and voice messaging systems. Businesses are global rather than local. Relocating businesses are welcomed with open arms by regional development agencies (RDAs), set up to co-ordinate strategic planning, channel funding and work with local organisations to bring in new businesses. (48) "We are about supporting existing businesses and jobs but we also want to bring new employers into areas and encourage organic growth and entrepreneurs," says a spokesman for the National Secretariat of Regional Development Agencies. RDAs are also helping to tackle problems holding some cities back. (49) Unskilled or elderly workforces, lack of technological knowledge, poor facilities, inadequate infrastructure and gaps in broadband availability can all combine to put businesses off relocating. On current form, the best place in the UK to do business is Leeds, according to specialist research consultancy OMIS, which advises companies on relocation. (50) OMIS"s latest Britain"s Best Cities report gives Leeds high marks for its skilled and educated workforce, availability of office space and regenerated city centre full of new shops and restaurants.
