I'm an engineer and was contacted by ERG to fix a leak for one of their customers. Leak fixed, invoice sent to ERG (payment terms agreed at 30 days). 87 days later and I'm still waiting for payment. Numerous emails sent to ERG accounts department who say 'we'll look into it' and then nothing. Customers - you will be over charged if you use this company. Go direct to a local tradesman in your area (use chckatrade for example). Tradesman/Contractors - do not do work for this company. They will not pay you. ERG trades as 'ERG Facilities' and 'ERG Facilities LTD'.
