Our Water Efficiency Services Include:

Building Regulations Part G Compliance

All new dwellings must demonstrate that they do not exceed the daily water consumption limit set out in Part G. We provide official calculations using approved methodologies to meet this requirement.

Water Usage Assessment

Using your project’s specifications and design data, we carry out detailed assessments of anticipated water consumption. This includes fittings, appliances, and system types to provide a clear picture of usage.

Compliance Documentation

We deliver a comprehensive Water Efficiency Report that can be submitted to Building Control or your assessor. The report includes usage figures, compliance confirmation, and a breakdown of each water-consuming element.

Design Recommendations

If your design is close to or exceeds the water usage threshold, we provide practical suggestions to reduce consumption and achieve compliance – including fixture choices and system alternatives.
