By providing regular up-to-date water meter readings, you can help to ensure your business water bills are calculated to reflect your actual usage. With many businesses operating out of the norm, it makes sense to submit meter readings more often.

Can I submit my own reads?

Yes – we are happy to accept customer reads in addition to our own annual reads. You can submit your own meter reads on our website. Our meter readers have also given their five top tips on finding and reading your water meter.

I've taken a meter reading and it doesn't reflect my bill - can I be re-invoiced?

We will re-evaluate your payments when issuing your new invoice. Where we have an up to date read, this will ensure your bill is as accurate as possible. When we have to use a read that is a little older, we will use the last two reads to estimate your average daily consumption. This average consumption will help us calculate the charges between your last meter read and your bill date. If you are concerned your bill doesn’t reflect your consumption, please get in touch to discuss this further. Remember to have an up to date read to hand.

My bill says estimated usage, but I send readings regularly

As most of our invoices aren’t produced on the date of your last reading, we may have to estimate a few days or weeks’ worth of charges. Therefore, our bills say ‘estimated usage’ by default. All our estimates are based on actual reads, and submitting your own meter reads will ensure there is always an up-to-date meter read for us to use when calculating your next invoice.


My bill has changed since moving to Castle Water. I thought my previous supplier was taking readings?

There may be a number of reasons your bill has changed since moving to Castle Water. Some of these are:

  • More frequent reads
  • Seasonal usage
  • Meter installation
  • Faulty meter

Previous supplier marking ‘estimate’ reads as ‘actual reads’

If you have any concerns about the consumption we have estimated for your property, please get in touch with us as soon as possible. Any reads you have taken yourself will be useful, so please have these to hand.
