Readers' forum : Jersey services

I have an electrician client who is VAT-registered in the UK but carries out a lot of work in Jersey. He has been claiming Jersey VAT on his UK VAT returns – mainly on hotel bills – which appears to be at 5% and is described as goods and services tax (GST). He is worried that his claims are wrong.
