We’re saving NFUS members
£39,000 per year on water bills

Great water service that saves time and money

We’re creating better water, wastewater and trade effluent services for farming and agriculture businesses in Scotland.

2024 marks the 10th year of partnership between NFUS and Castle Water. For too long, farmers and growers had been left out of the benefits of the competitive water market in Scotland, that’s why we chose to partner with NFUS partnered and offer a deal that secures preferential water and wastewater rates for NFUS members.

We estimate we are currently saving NFUS members £39,000 on annual bills. We haven’t yet found a NFUS member who pays water charges where we can’t offer worthwhile savings. The partnership between NFUS and Castle Water was the first affinity partnership in the water sector, and we continue to look for opportunities to support NFUS.

Discounted NFUS member water rates

Our affinity partnership with NFUS delivers worthwhile savings, and with a smooth switching process, straightforward billing, simple ways to manage your account online, support to improve sustainability, and specialised Agriculture Wastewater Treatment Services, we have everything you need get the most from your water services in Scotland. Our Scotland-based team handle the switch for you.

Don't settle for bad service
and misleading quotes

Other water retailers fail to take over 20% of the meter readings for which they are responsible, and it’s strongly suspected that they have a much higher failure rate with rural customers. We’re the only water retailer that’s invested in our own meter reading team and we achieve on time readings in 99% of cases in Scotland. We make it easy for our customers to submit their own water meter readings online all year round to keep bills low.

Unlike other business water retailers, our quotes don’t have hidden retail fees in the small print, and we don’t do exit charges. We have more 5-star customer reviews and more directly employed meter readers than any other UK water retailer.

Limpet readers

Is your water meter difficult to read?

You need an accurate, low cost solution to hassle-free meter readings

Limpet readers are a budget friendly option for businesses looking to avoid skipped meter readings, eliminate estimated billing, and minimise the hassle of monthly meter readings, by providing 100% accurate readings directly to your device.

Quick and easy to set up, Limpet readers help to keep your business water bills up-to-date and improve safety by removing the need to open meter manholes to collect meter readings.

The benefits of limpet readers

  • Track water consumption
  • Improve safety and physical benefits

How do limpet readers work?

The Limpet reader attaches to your existing water meter. The device takes a photo of the meter reading and converts the image into accurate numerical readings (as displayed on your meter). The meter reading data is transmitted to a database, that stores your readings with corresponding dates, before being sent to your mobile device.

The devices offer the flexibility to set up in advance how often you would like to receive your water meter readings. Typically businesses set Limpet readers to provide monthly readings.
