The products are a two-year tracker accelerator mortgage with an initial rate of 5.5% and a two-year discount rate arrears mortgage with an initial rate of 4.74%.

Both products have guaranteed stage payments based on cost and no requirement for interim valuations during the build.

Clients can borrow up to 85% on their land and build costs, with a maximum final LTV of 80% with both products.

The products will look to support intermediaries and their homebuilding clients.

Tom Gurrie, head of intermediary sales at Vernon Building Society, said self- and custom-build was a highly specialised, but important part of a diverse housing market.
