It takes a lot for me to waste time writing a review but castle water have done enough to deserve this. I inherited them when I moved into a property. It has taken me 4 months to move companies after they blocked 4 attempts to switch. When I called to find out why they couldn’t explain. On one call I was told it was because I made a complaint!! They sent me £116 bill for 10 days use based on previous tenant (even though the premises was barely even occupied) even when I submitted readings they refused to alter their bills and forced me to pay them.They also had the wrong address from the start. I explained this and they tried to charge me £210 to change it. I wouldn’t be surprised to hear the mafia were operating this company. Now reported to OFWAT. Dont contract with them unless you’re prepared to give up hours of you working days to argue. Although apparently if you do, you might stand a chance of compensation because they will most certainly make your life a living hell.
