It's been calculated that 83k on each 230k new build goes back to Exchequer in levies and taxes. This is over 30% of each new build costs.Would reducing the payment to the local authority to get a site serviced not be a better option?
The measures could be wider, VAT is only 13.5%. Scrapping development levies would shake the market even more.
Pushing the costs of building social housing on the young struggling families looking to buy a home is also cruel. Social housing should be financed from the general taxation. Currently developers pay huge money to free themselves from the requirement of providing X % of social houses in each estate. This cost is and must be pushed further on the buyer - there's no other way.
