About National Inventory Services
Compliance, Delivered with Confidence.
At National Inventory Services, we’re setting a new standard for inventory and compliance reporting in the Build-to-Rent and large portfolio rental sectors. We believe that asset protection, legal compliance, and operational efficiency should be built-in, not bolted on.


Our Mission
To make inventory and compliance reporting effortless, accurate, and scalable for the UK’s most forward-thinking rental property operators. We exist to eliminate uncertainty, resolve disputes, and establish professional consistency in a fragmented sector.
Who We Are

Unlike freelance-based networks or patchwork clerk models, we offer a unified, accountable, and professional approach tailored to the needs of institutional landlords and Build-to-Rent developers.
With experience in property management, compliance law, and asset reporting, our leadership team understands the pressures that BTR operators face. Our services are designed to align with your workflows, compliance requirements, and brand standards.

- End-to-end reporting for the full tenancy lifecycle
- Consistent national coverage with trained, vetted clerks
