Built on Over Three Decades of Enforcement Excellence.
National Warrant Services Ltd was founded with a single purpose: to protect energy suppliers from the financial and operational impact of theft and fraud. Today, we are the UK's most trusted revenue protection partner.
Our Story
National Warrant Services Ltd was established by a team of former enforcement professionals who recognised a gap in the market: energy suppliers needed a specialist partner who could combine investigative expertise with rapid, compliant enforcement capability.
Over three decades, we have grown from a regional operation into a truly national force — with trained agents deployed across England, Scotland, and Wales. We have executed Nationwide warrants and recovered millions in lost revenue for some of the UK's largest energy suppliers.
Our approach has never changed: rigorous investigation, full legal compliance, and an unwavering commitment to results. We don't cut corners. We protect your revenue the right way.
