Data is not published
Unlike Scotland (Historic Scotland), Wales (Cadw) & Northern Ireland (Department of the Environment) where the information is available under the Open Government Licence, the information for England is only available from English Heritage on a non-commercial basis.
Split the data into a number of smaller list by counties (or smaller area), which can then be made available on the English Wikipedia. See <https://en.wikipedia.org/wiki/Category:Lists_of_Grade_I_listed_buildings_in_England_by_county> for example of structure and <http://en.wikipedia.org/wiki/National_Register_of_Historic_Places_listings_in_Richmond_County,_New_York> for an example of what it may look like. The lists can then be utilised for the UK to take part in the world's largest photo competition <http://www.guinnessworldrecords.com/records-6000/largest-photography-competition/> : Wiki Loves Monuments.
The UK is one of the largest technological advanced country, and one of very few European countries that have not taken part in Wiki Loves Monuments <https://commons.wikimedia.org/wiki/File:Participating_Countries_WLM_2012.svg>. By taking part in Wiki Loves Monuments, we will expect to gain approximately 10,000 photographs of buildings of national or international importance and interest. These photographs will all be available for public reuse on Wikimedia Commons under free licenses. A number of these will also be used to illustrate individual articles on our listed buildings, as well as the lists previously created on Wikipedia, one of the world's most popular website and the de facto location for information for most people.
