Water Calculations

Water Efficiency Calculations

Water efficiency calculations are required by the Government in the United Kingdom under Part G of the building regulations. 

All new developments and properties require water calculations to help ensure that they have suitable water provisions to accommodate proposed activities. Additionally, water calculations also help to ensure that the maximum amount of water being used by a person within a property or development does not exceed a limit of 125 litres of water, per person each day.

What is involved in water calculations?

Through our nationwide network of experts, we are able to perform water calculations according to the latest advice, guidance and requirements under Section G of the Building Regulations. This includes expert assessment and advice if our water calculations highlight any inefficiencies or the need for improvement. Water calculations can be performed to comply across a range of levels, from mandatory minimum requirement performance, to helping make a greener, more energy efficient development through attaining zero carbon status. 

We have expertise and experience in helping our clients attain the level of efficiency their project requires through our reliable water calculation processes. This includes knowledge of a range of areas relevant to attaining acceptable water calculations, including fittings versus measured approaches to water calculation, advice regarding high pressure and low-pressure systems, as well as information regarding options for water calculation in grey-water systems and rain-water type systems.


How can I improve water efficiency?

If our water calculations show that your water efficiency is currently at unacceptable levels, we can use our years of experience to offer practical, efficient solutions to help you boost up the results of your water calculations. 

Each property and development is unique when it comes to water calculations, and we encourage you to get in touch as early possible to ensure your water calculations are as successful as possible. Some common measures to improve poor performance on water calculations can include installation of water flow restrictors, low-flow shower heads and low-flush toilet units.

Do I need water calculations?

Achieving minimum efficiency standards for water calculations are required under Section G of the Building Regulations. If you have a new development, or are converting an existing development for a new purpose, it is likely that you will require water calculations performed.

Our unrivalled service includes free, expert advice for helping properties achieve required efficiency levels through water calculations. Simply the use the contact form on this page, or call our offices, to chat about your water calculation assessment requirements with our friendly and knowledgeable team of acoustic consultants.

Sound Absorption Vs Sound Insulation? What’s the big difference?

Sound absorption refers to the loss of sound energy when sound waves hit ceilings, walls and floors, and they are absorbed. Materials that are absorbent are often used so that a particular building is soundproofed to reduce the amount of reverberation, which has an impact on the way a particular room sounds.

How to Install Resilient Bars?

Resilient bars allow secure fixing of plasterboard or other boards to timber joints while improving the acoustic insulation of walls or ceilings. When properly installed, they allow the wall or ceiling to flex slightly, which absorbs sound.
