VAT (Value Added Tax): Official Rates & Who They Are For
The UK VAT system applies three core rates to trade contracting: Standard (20%), Reduced (5%), and Zero (0%). Which rate applies depends strictly on whether the property is existing, undergoing energy-efficiency retrofit, or being constructed from the ground up as a new residential dwelling.
