DesignBuilder Software only provides annual Energy Assessor packages and Certification module licences because this is the easiest way to ensure that you remain up to date with Government legislation.

With an annual license, you pay the license fee each year and DesignBuilder provides up-to-date software over that period including the periodic changes to SBEM introduced by Government. Towards the end of the subscription period we send you a reminder to re-subscribe to maintain continuity of the service, with a 10% discount available for renewing in advance.
