Are you on a water meter? If you're in credit you can get a refund.
Ring 'em and find out. I'm in credit too.
Yes, I'm on a meter, but I'm sure that this credit is not reflective of how much I owe them. I've been on payment plans, threatened with court action etc in the past. Call centre agents have been unable to explain how bills have got so high. I'm not going to touch that credit.
My calls with them usually result in me saying "I've got a direct debit, just take whatever the water costs each month" and they say "Sorry, we assessed your water usage would be £38 per month but it's actually £54 a month so you've only paid £456 instead of £648. Please give us £192 this instance or else we'll call the bailiffs and fuck your credit record".
I bet that if I ask for my £200 back, I'll fritter it away, then Thames Water will pull another £200 bill out of the sky and I'll be left fuming.
And, no joke, I've just looked it up and I'm now £238 in credit. I pay £43 per month so if I was charged nothing at all, that would take almost six months to build up. I had previously been paying £80 per month. Then, having been moved to £22 per month I was £250 short last August and had to pay that over the phone. The only thing I know is that
editor is in for a pain in the area now he deals with them directly.
Edit: Sorry to go on about this, but I have started looking into it a bit more.
discobastard my bills went into credit in September 2019. There's something there in the summary which says
Cancelled charges to allow issue of revised bill -£308.37. I end up £55 in credit. In my March 2020 bill I have a line of
Transferred payment (credit) -£98.02. No idea what either of these represent, but am sure that if I go looking for the credit in my account, they will hammer me for credits that they shouldn't have given me.
Final edit: I phoned Thames Water, they told me that while I do have a credit balance, it will be used to pay for future bills so not to touch it. I pointed out that my credit balance had gone up from the one before last so she says she will put the amount I am paying down, as low as £5 if I want. This, I suspect, will lead me to go into arrears. It is all a shambles.
