I called Plumbing Force to my boiler which intermittently would fail to ignite. The original appointment was cancelled by them at short notice and re-scheduled. The engineer diagnosed the fault was due to low gas pressure and arranged for Northern Gas to replace the regulator and I was charged £237.60 by Plumbing Force. Whether there was a fault with the regulator or not I do not know, but the problem continued. I arranged a further appointment for Plumbing Force to return but again this was cancelled by them on two further occasions at short notice. Utterly frustrated with Plumbing Force I then called a Vaillant engineer who diagnosed faults internally with the gas valve, spark electrode and burner gasket and following replacement the boiler has continued to work without fault. I complained to Plumbing Force about the cancellation of appointments at short notice and about the poor standard of the engineer who was not familiar with the boiler, could not correctly diagnose the fault and had no relevant parts even if he had. The utter contempt and disregard Plumbing Force then displayed towards me is breath-taking. They did absolutely nothing to address my concerns and simply ignored my complaint even after I wrote personally to the Director. This shows a lack of professionalism and governance that is not acceptable by a company acting in the public service and endorsed by the Gas Safe Register. Having further ignored my request for a letter of deadlock I attempted to complain to the retail ombudsman, but Plumbing Force are not listed under the UtilitiesADR Home Services Providers Membership list which speaks volumes about this company. While I cannot comment on the safety standard of work carried out by Plumbing Force (the engineer actually did nothing other than charge for his time) the disdain shown by this company is appalling and I would urge any customer to keep well away
