As a benefit of membership, NHER members who have lodged more than 20 EPCs in the previous year are entitled to free setup (for a single user account) of the service and have the facility to use it on a pay on use basis at £1.00 + VAT per transaction.  A transaction is defined as either the creation of a new report or the finalisation of a measure.

Members can also benefit from volume discounts through contracting to the service for a 3, 6 or 12 month period and paying a monthly charge.  The monthly charge, payable in arrears, provides access to a number of inclusive ECO transactions over the contract period with higher monthly charges and longer contract durations providing higher levels of discounts. 

NES ECO Online v1.1 is tailor made software for calculating ECO scores for reporting to Ofgem or forecasting. This web based software can be accessed at
