Yes, you can, and as you may be able to get a self-build mortgage with a relatively small deposit, it’s an affordable option. Your money will also go further if you’re building your own home versus buying an existing one. In England, the Help to Build equity loan scheme could make it more affordable as you may be able to take out an equity loan of up to 20% of the land and build costs (40% in London), which means you can take out a smaller mortgage.
