In 2023 we bought and refurbished a house which had been empty for a few years. I have now found out that due to it being empty for 2+ years, we could have had a certificate in place to pay just 5% VAT on the associated renovation costs.
Does anyone know if there is a way to claim this back retrospectively now? I still have all invoices which state the VAT paid at 20%. Can’t find anything online about how to go about this so would appreciate any guidance.
