Some energy efficiency measures have a good return on investment but cost a lot upfront. It is up to your organisation to choose how to fund this kind of measure. Some companies offer a “shared savings” finance model, where the supplier or a third-party finance company covers the cost of the work, then the organisation repays the cost through an agreed percentage of the energy savings achieved. Your lead assessor should be able to advise you on the best options for financing your energy efficiency work.
