Financial Stability and Investment
By 2004, the Trust was opening the Park to the public every day as a museum. Additionally, a number of buildings were taken over and renovated by a private company, Bletchley Park Capital Partners, and put into use as serviced office accommodation, providing a supporting income stream for the Trust. In April 2006 Simon Greenish was appointed as CEO of the Bletchley Park Trust. In spite of all of its successes, Bletchley Park had reached a critical point. Minimal maintenance had been undertaken on the site since the war and its buildings were in disrepair; some of the iconic Codebreaking huts were derelict and the Mansion suffering major roof leaks endangering the building.
In 2007, Block H was leased to the Codes and Ciphers Heritage Trust for use as The National Museum of Computing. In late 2008, English Heritage stepped in with investment of £330,000 to repair the mansion roof at the same time offering a further £100,000 per year for the following three years, subject to another body offering match funding, to deal with a large backlog of maintenance and repairs. Early in 2009, Milton Keynes Council went to the public vote as to whether they should provide this funding and responding residents voted overwhelmingly in favour. In the 2010, the Department of Culture, Media and Sport invested £250,000 in the infrastructure of the site enabling repairs needed to support the steady growth in visitor numbers. In 2011, Iain Standen was appointed CEO of the Bletchley Park Trust and later that year was able to announce that the Trust had raised the £2.4 million needed to match fund a Heritage Lottery Fund grant of £5 million to begin the work of transforming Bletchley Park into a world-class heritage and education centre.
