They should be maintained because of historical values. It is part of the country's culture. (I am currently working on this topic and wanted some ideas from the public, thanks for helping)
Thanks for responding, actually I am not a debater so I am not too familiar with the game. I just want to have some ideas and thought from the public about this issue.
Listed buildings are building which have high historical and architectural value, such as the Palace of Westminster in London which is a famous tourist point. It also is an important building for the two houses for UK government.
They should be maintained well and be protected to ensure that they can act as a symbol of English heritage.
I feel as though protecting them as a symbol of english heritage is nice and everything, however, if it is costing the government money that we don't have or it becomes a public health risk that they should be condemned.
Buildings will be carefully assessed and checked before they become listed. Not all old buildings can be listed buildings, only the ones with special interest and importance will be considered. The government will control the amount spent on maintaining them, but after good maintenance, they can be opened to the public and earn back the amount from entrance fees and donations.
