Walthamstow packs a huge number of small businesses into its market, high street and growing food scene — one of the densest concentrations of independent firms in East London.
Since the business water market opened in 2017, companies in England (and Scotland since 2008) can choose who bills them for water. Win Energy helps Walthamstow businesses compare water retailers — and, just as importantly, checks your existing bill for the overcharges that quietly add up.
What we check for Walthamstow businesses
We look line by line: are you paying surface-water drainage you do not use? Are your reads actual or estimated? Are your meter size and tariff right? Fixing errors like these can uncover backdated refunds as well as future savings — often worth more than switching alone.
No disruption to your supply
Switching only changes the retailer that bills you. The water itself, and the pipes, stay exactly the same, so there is no interruption and no work on your Walthamstow premises. We will be honest, too: where the saving is in fixing your bill rather than switching, we will say so.
