What is it?

Working with Kingston & Sutton, LOTI has developed a this guidance for boroughs and Housing Associations participating in the Warmer Homes London programme to procure IoT (Internet of Things) monitoring solutions for retrofit projects. IoT sensors enable continuous monitoring of property performance before and after retrofit interventions, providing evidence of improvement while also helping identify residents at risk of fuel poverty, damp and mould, or overheating.

Why did we create it?

This document provides practical guidance for procuring IoT monitoring solutions that meet the technical, regulatory, and operational requirements of social housing retrofit programmes. It consolidates best practices from LOTI, national standards, and London borough experience.

What will it help with?

• Strategic Alignment: Understand why this technology is being deployed and how it fits into the broader Warmer Homes London programme.
• Technical Benchmarking: Set your minimum hardware and software requirements.
• Operational Execution: The “how-to” regarding resident trust, legal procurement routes, and phased rollout.
• Governance & Compliance: Ensure your data handling and contracts are legally sound.
  Tendering: A ready-made “Question Bank” to insert directly into your procurement documents.

Who should use it?

The guide is designed for use by:

• Retrofit Programme leads
• Procurement teams
• Information Governance teams
• Data and digital teams
