No. Grafto is run from Suffolk, where Green & Home Ltd has its warehouse in Mildenhall (registered office: Hertford). We work with businesses in Cardiff remotely: the AI Tools Report, the apps and support are all online or by email. Our only in-person events are in Bury St Edmunds.
It depends on what you do, but on the local mix we would usually start with AI Tools Report. Ten minutes of questions, then a costed nine-slide plan: which jobs AI can take off you, which tools, what they cost. £59.99 inc VAT.
From the Office for National Statistics’ UK Business Counts for 2026, published through Nomis. They count 12,120 enterprises registered for VAT and/or PAYE in Cardiff, so very small unregistered sole traders are not included.
