The main barriers to deployment were identified as part of the UK's broadband strategy ““Britain's Superfast Broadband Future””, published in December 2010. Work to address these issues—such as ensuring the business rate regime is appropriate, and examining options for deploying new overhead infrastructure—is ongoing. As well as this, the Department has delivered a number of outcomes including the publication of the advice note on micro trenching and street works, published in November 2011. Where barriers exist, we are committed to working with industry to remove them where possible.Regarding access to existing infrastructure, BT were required to offer access to their infrastructure as part of Ofcom's most recent 'Wholesale Local Access Review', published in October 2010. Ofcom have worked closely with industry to bring these products to market and have been available for competitors to use since November 2011. The implementation of the EU Communications Regulatory Framework in May 2011 also gave Ofcom the power to impose infrastructure sharing on other telecoms infrastructure where proportionate. This will be entirely Ofcom's decision.
