Had boiler installed by Polaris Plumbing and Heating. Sunny was polite courteous and very focused on customer service. From the initial quotation, it was clear that Sunny was customer focused and it was very important that his companies image was projected correctly. I had my boiler installed, really good work, very happy. I had a separate issue, which Sunny sorted straight away and was extremely helpful, don't go anywhere else, use Polaris Plumbing and Heating. May not be the cheapest, by absolutely worth that small amount extra.
