These terms were last reviewed on 2 September 2017.
The purpose of this site is to publish information that might be useful to understand or challenge regulatory and commercial arrangements in the electricity supply industry in the UK, in particular distribution use of system charges in England, Scotland and Wales.
I publish this material in the hope that it might prove useful to someone, in order to improve the openness of the arrangements in the industry, and in order to promote my consultancy services.
Privacy promise: This site does not try to track you. Should I ever want to introduce any kind of user tracking, I will put a prominent notice on each page of the site for at least six weeks before changes come into effect.
The information and software on this site is provided "as is" and any express or implied warranties, including, but not limited to, the implied warranties of merchantability and fitness for a particular purpose are disclaimed. In no event shall I or any other contributors be liable for any direct, indirect, incidental, special, exemplary, or consequential damages (including, but not limited to, procurement of substitute goods or services; loss of use, data, or profits; or business interruption) however caused and on any theory of liability, whether in contract, strict liability, or tort (including negligence or otherwise) arising in any way out of the use of this software, even if advised of the possibility of such damage.
In other words: mistakes can happen; you have not paid for information from this site; thank you for not being too silly if something does go wrong.
I have tried to make this site work with a wide range of devices, including screen readers. But I cannot test on every type of device.
If something does not work for you, tell me about it: email firstname.lastname@example.org. I would particularly welcome feedback from iPad users.
Spreadsheet models and source code come with explicit and permissive open-source BSD-style copyright licences.
Text and other materials created specifically for this site are under my copyright. My policy is as follows:
Electricity companies, their associations, DCUSA Limited, Reckon LLP, the Crown and others might make some copyright claims over some of the material included or linked on this site. I believe that what I am doing is permissible and fair. Contact me at email@example.com if you disagree.
If you spot an error or omission on this site, please contact me at firstname.lastname@example.org. I will correct mistakes. I will let you choose whether you get the credit or stay in the shadows.
You might not agree with some of the opinions that I express on this site. I am not hard to find and I enjoy intelligent debate.
There is no comment facility or online discussion forum. I thought that it would be too hard to keep such a system free of spam, personal information and false information. If you really feel the urge to shout on the web that I am completely wrong, get your own site.
