Question to the Department for Digital, Culture, Media & Sport:

To ask the Secretary of State for Culture, Media and Sport, how many new telecommunications masts have been erected in rural areas since the agreement with the four mobile network operators in December 2014 guaranteeing voice and text coverage from each operator across 90 per cent of the UK by 2017.

Neither DCMS nor Ofcom hold consistent time series data on the number of masts used by mobile network operators. Analysys Mason's report on the Financial Impact of Electronic Communications Code Changes, published 17 May 2016, estimated there were currently 33,000 physical sites hosting mobile communications across the UK, consisting of mobile towers or rooftops.
