When someone in Cardiff types "best plumber near me" into ChatGPT or Perplexity, the model names two or three businesses. This page is how Cardiff plumbers make sure they are on that list.
Cardiff has around 370,000 residents. Housing stock varies: Edwardian terraces in Roath, Victorian bay-fronts in Pontcanna and new-builds in Cardiff Bay. When a homeowner in Roath, Pontcanna or Whitchurch hits a burst pipe at 11pm on a Sunday, the first search now often happens inside ChatGPT, Perplexity or Google AI Overviews rather than on page one of Google. The model answers with two or three named businesses. Every plumber not on that list is invisible for that query.
Typical Cardiff pricing for a plumber is £70 to £150 for a standard call-out, £90 per hour for emergency work. Work covered includes boiler repair, leak detection, bathroom installs. Where regulation applies, customers expect to see Gas Safe Register credentials on the homepage. AI models read the same homepage; they weigh plain-language pricing, clear service lists and structured schema far more than they weigh marketing copy.
A worked example from our 20-questions list: a Cardiff customer types "best plumber in Cardiff for boiler repair" into ChatGPT. The model pulls from FAQ schema, LocalBusiness schema and the first 40 words of candidate homepages. If your site has none of those three signals, you will not be cited, regardless of how long you have traded in Cardiff.
