In October 2025, Natural England confirmed that water neutrality restrictions no longer apply in the Sussex North Water Supply Zone (SNWSZ), ending the four-year pause on development in the region. This major policy shift follows new evidence and a package of ecological measures. You can read our full analysis of what this means for your project on our blog here.
Cost and timing
Before we quote, we look at your proposed development and where it is, so we can explain what water neutrality or water efficiency information your application needs and how long the work is likely to take. Your quote sets out the fee, what is included and any exclusions, so you know what you are agreeing to before appointing us.
Quotes are free and with no obligation.
An address and a short description give us enough to begin. Plans or planning comments are helpful if you have them.
We confirm what applies to your site now that the Sussex North restrictions have been lifted.
Once appointed, we prepare the water demand calculations and supporting statement for your application.
Here are answers to common questions about this work. If you would like to discuss your own site, we can help you work out what is needed.
Send the site location, existing and proposed use, and any planning advice you have received. We check the relevant catchment and local requirements before agreeing the assessment.
Yes. We review the available information and explain what can be used, what needs updating and how the findings may affect the proposed design.
The site location, a short description of your plans and any comments from your planning authority are a useful starting point. If you have drawings or previous reports, share those too; we can help you work out what else is needed when we discuss the project.
After reviewing your plans and the information available, we provide a quote explaining the work, fee and expected timing. We also talk through any surveys, data requests or decisions from other organisations that may affect the programme.
