If you’re building or renovating a property in the UK, you’ve likely come across the term Water Efficiency Certificate. It’s a key requirement for demonstrating compliance with building regulations in England and Wales, but what does it entail, and how can you obtain one? In this guide, we’ll break it all down for you.

What Is a Water Efficiency Certificate?

A Water Efficiency Certificate confirms that a property meets the required water usage standards set out in the Building Regulations (Approved Document G). These standards are designed to ensure new homes are built with sustainability in mind, limiting water usage to:

• Maximum 125 litres per person per day for general compliance.
• Optional target of 110 litres per person per day in areas where stricter regulations apply (e.g., water-stressed areas).

This certification is a critical step in obtaining final approval for your build from your local authority.

Why Is It Important?

Water is one of our planet’s most valuable resources, and the UK faces growing challenges with water supply due to climate change and population growth. The Water Efficiency Certificate ensures that new builds contribute to:

• Reduced water wastage through efficient design and fixtures.
• Lower utility bills for homeowners.
• Environmental sustainability by preserving water resources.

For developers, failing to provide this certificate can delay project approvals and increase costs.

How Is Water Efficiency Calculated?

To issue a Water Efficiency Certificate, your property’s water consumption is assessed based on factors such as:

1. Flow rates of taps and showers – How much water is used per minute.
2. Toilet flush volumes – The amount of water used per flush.
3. Appliance water use – Washing machines and dishwashers.
4. Bath size and overflow capacity.
5. Outdoor water usage – For example, garden irrigation systems.

These inputs are used to calculate the average daily water consumption per person in the property.
