Absolutely the worst experience with regard to service from supposed pros. They took my bank details quoted £145 +vat for a boiler service and to look at a control panel issue and informed me that there may be a further charge for parts which would be notified before any works were carried out. They took £340 from my a/c with no additional works carried out, never issued a customer ref no/job no, 6+ calls and 3 weeks later I’m still waiting on an invoice and a refund. The gas engineer issued a cert stating the boiler had passed but required parts????? May not be safety critical but will be reporting to gas safe anyway.
