The survey also revealed that half of United Kingdom voters would like to see a referendum asking between the deal suggested by the government, no deal and remaining in the EU.
The result of the survey comes with less than eight months remaining before Britain is due to leave the European Union and as the United Kingdom "accelerates" preparations for a potential "no deal" exit from the European Union on World Trade Organisation (WTO) terms.
The shift in public opinion comes as Mrs May has stepped up planning for a so called "no-deal" Brexit that would see the world's fifth largest economy crash out of the European Union on March 29, 2019, without a trade agreement.
The survey of 1,466 Sky customers earlier in the month found that 65 percent of British voters now believe that the government will end up with a bad Brexit deal, an increase of 15 percent compared to similar polling from March.

Despite setting career bests in strikeouts and ERA a year ago , the right-hander struggled mightily earlier this season. McKinney has played two games for the Yankees , filling in on March 30-31 because of injuries to other outfielders.
The Sky poll showed 78 per cent of the public think May's government is doing a bad job on negotiating Brexit, up 23 percentage points from March, while just 10 per cent thought the government was doing a good job.
Results of a poll by Sky Data were release on Monday, and they showed that 50% of the public support a referendum on the final deal and 40% do not. "I'm surprised people said they want a second referendum".
When asked to choose between three options - Mrs May's deal, a no deal or staying in the European Union - 48pc said they would prefer to stay in the European Union, 27pc wanted to leave with no deal and 13pc would opt for the government's deal.
