How to get connected 

You have decided you want to inject biomethane into the Cadent network. Please find below our eight key steps which will guide you through the connection process. 

These have been split into two key areas: 

The commercial element of the process is detailed in steps 1-4 below. Here you will find the guidance, and documents you will need to complete when you are progressing through each step.

Step 1 - Process

You complete our initial enquiry form providing the following key information:

  • site location
  • postcode
  • estimated flow rate - standard cubic meters per hour (scm/h) of biomethane for injection into the pipeline grid network

We perform a high level network analysis and mapping to assess whether a connection is possible.

We will talk to you about this once the Initial Enquiry has been completed.

There is no charge to you for this activity.

Step 2 - Process

There are two types of Detailed Analysis Study (DAS); a Standard DAS and a Capacity Only DAS.

A Standard DAS will provide you with the following:

  • network entry connection options
  • indication of costs to connect
  • plant and equipment required to be provided by the customer
  • details of proposed site and pipeline route
  • network capacity flows, and constraints

A Capacity Only DAS, this will provide you with:

  • network entry connection options
  • estimate of the programme of works required to deliver a connection
  • other issues relevant to providing a connection

Details of where to send the DAS to are contained within the application form.


A Standard DAS costs £950 + VAT

A Capacity Only DAS costs £750 + VAT


Detailed Analysis Study 30 working days from receipt of payment

Following receipt of your signed agreement, you will be invoiced. Once we have received payment the study will be completed and issued within 30 working days.

The DAS is a snapshot of the network at the current time and is not a guarantee of gas flow as the dynamics of the gas distribution network are subject to change.

Once you have reviewed your study we can discuss the next steps with you or you can proceed to Application to Connect – Step 3, when you are ready.
