Scrap all the govt 'initiatives' which end up costing millions and no-one uses. Things that spring to mind are the energy saving deals for insulation etc and the one in the last budget where people save for a house deposit in an Isa style account which the government matches. They cost huge amounts to implement, the take up is usually very low and there are often horrible unthought of consequences i.e. dozens of nuisance calls from companies offering to insulate the loft 'under the government initiative', many of whom are charlatans.
Many of the EU rules and regs stifle small businesses and also cause a rise in abovementioned charlatan companies offering to do PAT testing, fire risk assessments etc which under HSE are unnecessary. I don't want the UK out of the EU but do think we are under a massive burden from the sheer volume of additional EU requirements.
Charge overseas visitors to galleries/museums etc. We have to pay to visit galleries in Italy/France so think unless you have proof of UK residency you should pay to visit our world class museums.
No more QE, ever ever ever. It costs and the only people it benefits are already wealthy. There is little evidence of 'trickle down effect'.
Stop paying salaries to local councillors. People used to do the job for expenses (I'm sure a lot of expenses were padded but this could be scrutinised). Our councillors with 2 notable exceptions are a shower of lying pocket lining arses. They are either wealthy retirees, or have full time jobs on top of their council activities.
Build more housing - a wide range of options from studio apartments to 3 bed houses, good quality with good fences and soundproofing (!) and not all on estates, but spread across the whole residential gamut. 1% increase in housing in all towns and villages will not cause overcrowding or problems with transport etc - if you live in a village with 100 homes, then an extra one house will not cause problems - similarly a town with 10,000 homes is not going to be disadvantaged by having an extra 100 homes built. These homes should be social housing and NEVER be sold off to the tenants. There should be options for tenants to downsize once family leave home without having to move miles away because there is no smaller accommodation available.
