Comments and complaints

Whilst we aim to provide a quality service at all times there may be occasions when the service provided does not meet the standards that we set for ourselves or that you might expect from us. We have therefore established a simple complaints procedure so that problems can be resolved quickly and efficiently and to your satisfaction.

If you have a complaint, please contact us at complaints@sden.org.uk. Please note that we can also accept complaints by telephone and by post, though we will request that your complaint be made in writing if this is possible, subject to your individual circumstances and needs.

If you are not satisfied with the way in which your complaint is dealt with by the complaints management team, please contact the SDEN Managing Director Amanda Cherrington at amanda.cherrington@sden.org.uk.

If your complaint has not been resolved to your satisfaction within 8 weeks from the date on which you first contacted us about that complaint then you may escalate your complaint to the Energy Ombudsman. Please visit their website for full details.
