Water Part G Compliance Report & Part G Water Efficiency Assessments

A Water Part G Compliance Report assesses water efficiency within a proposed residential development and provides evidence of compliance with the water efficiency requirements of the Building Regulations.

Our consultants prepare water efficiency calculations and supporting reports for planning and Building Regulations purposes.

Water Efficiency Calculations

The assessment considers expected domestic water consumption based on the proposed fittings, appliances and sanitary installations.

We use the relevant information to calculate anticipated water consumption and determine whether the development meets the applicable performance requirements.

Part G Compliance

Part G of the Building Regulations includes requirements relating to sanitation, hot water safety and water efficiency.

Our reports provide the technical evidence required to demonstrate that the proposed development has addressed the relevant water efficiency requirements.

Efficient Fixtures and Fittings

Water consumption can be influenced by the specification of taps, showers, toilets, baths and appliances.

We can review proposed fittings and identify where changes may be required to achieve the target water consumption level.

Residential Development

Water efficiency assessments are particularly relevant to new residential developments and can be incorporated into the wider sustainability and building compliance strategy.

Early assessment allows the specification to be adjusted before construction documentation is finalised.

Supporting Compliance

Our reports provide clear calculations and supporting information for project teams, building control and other relevant stakeholders, helping to demonstrate compliance with the applicable requirements.

At the Syntegra Group, our Energy Certification team can provide guidance on targeted flow rates and consumption levels for different fitting as well as review and comment on specification to ensure that the requirement can be achieved in an appropriate strategy for the site.
