Having been looking at increasing our resilience and reducing our impact by using rainwater internally from a large Rainwater Tank, one thing to note is that it can also save us money. Firstly we need to get a meter fitted, so that we’ll only pay our standing charge plus actual water usage. If we’re not using any external water then, according to United Utilities’ Rate Sheet we could be paying as little as £43 a year – saving about £100 a year. Secondly we can apply for a reduction in our Sewerage charges as the water will no longer be entering the sewer. It’s not a huge reduction  – about £34 a year on the fixed charge, plus about £100 a year on consumption charges, but better than nothing! 

So in total we’ll probably save just over £200 a year – not enought o make it a no-brainer investment decision, but certainly a nice bonus for something we were already wanting to do.
