About BOSH
BOSH is a UK building-materials comparison platform in testing. We are developing tools to help people estimate quantities, compare retailer product prices and follow links to buy from retailers.
This public preview contains material guides and a working quantity calculator. Retailer feeds are awaiting approval and connection, so there are no live prices, stock claims or purchasing features here.
If approved, BOSH may earn commission when a visitor buys through an affiliate link. Those links will be clearly identified. No retailer partnership is implied by this preview.
