Portfolio Preparation

our deep knowledge of the UK utility landscape enables us to review every supplier of water to obtain the most competitive price for our clients.

with thousands of possible tariff combinations across four key services, including 130+ regional volumetric water tariffs alone, market leading bill validation protects you from errors and unnecessary costs that can go undiscovered, ensuring mistakes do not re-occur.

It takes 2 weeks to get initial prices from suppliers.

This varies depending on the supplier, but on average it takes 2-4 weeks to switch.

Water prices are made up of the wholesale cost + the suppliers management fee. You can’t fix the wholesale charges as these are reviewed every April (usually increasing), but some suppliers do offer fixed management fees.

As of November 2023, we tender out to 8 suppliers.

Wholesale costs are what the supplier is paying for the water, default costs are what the client will be charged if they aren’t in a water contract.

Only the supplier’s management fee can be negotiated as the majority of the price is the wholesaler’s costs.
