“The decision to appoint Nottingham City Council to support IKANO during the introduction of Phase 1 of ESOS was well justified. Their communicative, well-timed, and structured process helped minimise the workload to help meet the Environment Agencies requirement. This continued through Phase 2 with the same approach and value for money structure. So much so we are happy they can continue as we reach Phase 3” - Stephen Horgan, Facilities Manager at IKANO bank
