Expert business rates advice, appeals and audit — exclusively for UK power generation operators.
The 2026 revaluation takes effect 1 April 2026, with new rateable values based on a valuation date of 1 April 2024. Bills across the power sector will change — sometimes substantially. Navitas is currently reviewing portfolios across wind, solar and CCGT assets. Contact us now for a no-obligation assessment of your new position.

We know when to appeal and when to leave well alone. Our deep knowledge of how the VOA values power generating assets — from load factors to capacity constraints — gives us a genuine edge in negotiations. That forensic insight translates directly into successful appeals and measurable reductions in your liability.
2010 · 2017 · 2023 · 2026 ListsBilling errors on power assets are more common than most operators realise — and they compound quietly over time. We conduct a systematic audit of your rates bills across all sites, identifying overpayments, incorrectly applied reliefs and billing authority errors. Backdated refunds are frequently recoverable, and our audits consistently return more than their cost.
All Property TypesInvestment decisions made on inaccurate rates assumptions carry real financial risk. We provide detailed and high-level liability forecasts across existing and new sites — updated to reflect government announcements, pending revaluations and changes in market conditions. Whether you need a quick portfolio overview or a site-by-site model, we give you the numbers you can rely on.
Multi-Year ModellingRelief opportunities are frequently missed without specialist oversight. We proactively identify and pursue every applicable exemption across your portfolio — from temporary reductions during outages and generation constraints, to empty rates, Small Business Rates Relief and Enterprise Zone provisions. We are experienced across England, Wales and Scotland, where the rules and available reliefs differ materially.
England, Wales & ScotlandMany power operators are sitting on historic overpayments they don't know about. We conduct retrospective audits across past rating lists to identify errors, incorrectly calculated liabilities and missed reliefs — then pursue recovery on your behalf. Past errors do not simply expire, and a thorough historic audit frequently uncovers significant refunds.
All Rating ListsOur strong working relationship with the VOA allows us to pre-agree new assessments ahead of a revaluation or when a new asset is commissioned — removing the need for formal appeals and providing clear budgetary certainty from day one. Where sites have undergone physical changes, capacity upgrades or shifts in generation levels, we engage directly to ensure your Rateable Value reflects the true position.
VOA Engagement
MRICS · Founder & Managing Director
Owen spent over a decade at the Valuation Office Agency, working within the specialist Utilities Rating Team as Lead Surveyor — valuing CCGTs, coal-fired stations and the full range of renewable assets. He left the VOA in 2009 to advise the operators whose assets he had previously valued.
His advisory track record spans the 2010, 2017, 2023 and 2026 rating lists, covering England, Wales and Scotland — where he is also fully conversant with the distinct processes of the Scottish Assessors Association.
