Expert advisory at the intersection of energy, regulation, and finance.
Energy consulting. Financial assurance. Senior practitioners.
Smart GB Services is a specialist consultancy founded by Roger Hey CEng, providing senior-level expertise to organisations navigating complex challenges in the UK energy sector. With over 30 years of experience in electricity distribution, regulatory affairs, and grid modernisation, Roger established the company to offer genuine depth of knowledge to clients who need more than generalist resource.
In 2026, Smart GB Services expanded with a new financial controls and assurance division, led by Tiffany Hey ACA. Drawing on 29 years of public sector audit experience, the financial assurance division brings the same commitment to senior-level, practitioner-led delivery into the NHS, local government, and regulated energy sectors.
Energy Consulting
Regulatory affairs, grid modernisation strategy, and go-to-market advisory for organisations operating in the UK electricity distribution sector.
Financial Controls and Assurance
Internal audit, financial controls review, and capital programme assurance for public sector and regulated organisations.
Why Smart GB Services?
You work directly with senior practitioners, not junior staff or agency resource. We are engaged for specific outcomes on a project basis, with direct access to the people doing the work. Our presence across both energy and public services means we bring cross-sector insight that pure specialists in either field cannot offer.
