Pay as You Go (PAYG)

A Pay as You Go (PAYG) account enables you to pay for your water and waste services as you use them.

How does it work?

  • You enter your meter reading online or we will read your meter for you – usually every 30 days
  • We provide you with an accurate bill
  • You pay your bill within 14 days

Terms and conditions apply.

Am I eligible for PAYG?

PAYG is available for existing Castle Water customers in England with premises in the Thames Water, South East Water and Portsmouth Water areas. You can request a PAYG account if:

  • You have a metered supply
  • You agree to provide regular meter readings or request that we take the readings for you
  • There is no outstanding debt on your existing account

Please note, PAYG is not available to customers with an unmetered supply, who require trade effluent services, or who have previously signed up to a cashback agreement with Castle Water.

Terms and conditions apply.

Register your interest for a PAYG account

To request a new PAYG account:

  1. Clear all outstanding bills on your existing account
  2. Register your interest for a PAYG account
  3. Set up your payment method
  4. Submit your first meter reading or request that we take the reading for you

Request your PAYG bill

With PAYG, you can choose the period in which we bill you in order to suit your business needs. This can be anywhere between 30 days and 90 days following your previous invoice.

As a PAYG customer, you can generate your bill by either submitting your own meter readings or we can read your meter for you.

If you submit your own meter reads then these must be supplied no later than 85 days following the date of your last invoice.

If you request that we read your meter for you then this may incur an additional cost and may also be subject to VAT. Please see further details under ‘Request a Castle Water meter reading’ below.

Submit your meter reading

If you choose to submit your own meter reads, customers on our PAYG contract should submit a read every 30 days. You can submit meter readings quickly and easily online. How you do this will depend on where your premises are located.

What if I don’t submit a meter reading in time?

We must invoice you at least every 90 days. If you do not generate your own invoice within 85 days of your last invoice, we will raise an estimated bill for that 90-day period. You must pay this bill within 14 days.

PAYG Pricing

With a PAYG account, the price you pay for your water and waste services will be no higher than the default charges set by Ofwat. You can find the price that relates to your premises in the relevant Scheme of Charges.

Payment terms

  • PAYG invoices must be paid within 14 days.

What if I miss a payment?

If you miss a payment, we will send you a reminder. This must be paid within 7 days.

If you fail to pay the outstanding amount within 7 days, we will ask you to pay a security deposit to cover your payment obligations to us.  The deposit amount will be based on your estimated six-months consumption costs.

If you do not pay your reminder invoice and / or security deposit within 14 days of our request, you will no longer be eligible for our PAYG scheme. We will then continue to invoice you as per our standard billing arrangements.
