Need expert support with water efficiency and Part G compliance? Our experienced team helps you implement innovative water-saving technologies and practices. Ensuring your buildings meet the required standards for water usage and drainage is critical for promoting sustainable development.

Why is Part G Water Efficiency Important?

With years of expertise in regulatory compliance, our tailored water efficiency services ensure your building meets Part G requirements. Our team will assist in specifying water saving fixture, ensure compliance, and provide reports for Building Control.

For new builds, extensions, or conversions, a Part G assessment is essential to verify water use stays below either 125l/ 110l/105l or even 100l per person per day. By meeting these regulations, you help conserve water, lower operating costs, and support sustainability. Non-compliance can lead to delays in approvals and impact your overall EPC (Energy Performance Certificate) rating.

What Does a Part G Water Calculation Involve?

Working with our expert team ensures all aspects of water usage and efficiency are considered from design to construction phase. The Part G calculation focuses on evaluating the following key factors:

  • Water Supply: Ensuring an efficient water supply system is installed
  • Water Usage: Calculating water usage for various fixtures, including toilets, showers, and sinks
  • Sanitaryware and Fixtures: Checking water flow rates and fixture specifications to comply with water efficiency standards
  • Water Recycling: Considering any water-saving systems, such as greywater or rainwater harvesting

How We Can Help

At Energy Report, we make Part G compliance simple by offering both Design Stage Water Calculations and As Built Water Calculations:

Design Stage Water Calculations

Early in the design phase, we can provide guidance on the water-efficient fixtures and fittings that meet the required standards. This ensures compliance with the local planning authority or Building Control requirements before construction begins.

As Built Water Calculations

Once the build is completed, we will calculate the actual water usage based on the installed fixtures and fittings. This final calculation will ensure your property meets the water efficiency standards and is ready for approval.
