For both UK resident and non-resident owners, VAT will always need to be considered. As a general rule, VAT does not need to be (indeed cannot be) charged on rents to residential tenants. The downside of this is that a residential landlord cannot recover any of its associated VAT costs. However, if any works are to be carried out at a UK property, the UK “zero” and “reduced rates” should be considered carefully as they may reduce the VAT costs incurred (and may allow certain VAT costs to be recovered).
