Title: Innovative Senze Retrofit Tool Revolutionizes Energy Savings for Landlords with Data-Driven Precision

---

The race toward net-zero housing and energy-efficient homes has taken a significant leap forward with the launch of Senze, a pioneering retrofit tool designed to help landlords unlock substantial energy-related savings. By deploying real-time sensor technology and advanced data analytics, Senze offers landlords a precise, cost-effective, and scalable solution to improve housing energy performance—outperforming traditional methods reliant on visual inspections and estimated modeling.

What is the Senze Retrofit Tool?

Senze is a cutting-edge retrofit assessment platform developed by a team led by industry veterans including Related Argent chair David Partridge, Project Etopia founder Joseph Michael Daniels, and Veritherm founder Tom Fenton. The tool uses sensor technology installed in every room of a property to gather live data on thermal and energy performance. This approach replaces conventional reliance on Energy Performance Certificates (EPC) and desktop modeling with actual, real-world measurements[1][2].

By pinpointing where heat loss occurs and how efficiently a home performs, Senze allows landlords to precisely tailor retrofit improvements such as insulation, heating upgrades, and ventilation measures. The data-driven analysis supports more targeted interventions, reducing costs, minimizing unnecessary work, and accelerating project delivery.

Proven Success Across Multiple Pilot Programs

Senze has undergone successful trials with major social housing landlords and authorities, including Bromford Housing, the Northern Ireland Housing Executive, the Church of England, Greater Manchester Combined Authority, and the New York City Housing Authority[1][2]. These pilots have demonstrated measurable benefits, substantiating Senze's value proposition:

• One property was found to perform 59% better than its official EPC rating, preventing a costly and unnecessary external wall insulation project and saving the landlord £25,838 in capital retrofit costs[1][2].
• Across all pilot homes, the tool delivered average savings of £4,890 on retrofit works and £133.90 annually on fuel bills[1][2].
• Carbon emissions dropped by an average of 1.29 tonnes per home per year, reinforcing the tool’s environmental impact[1][2].
• The live data capture reduced the time spent on assessments and consultancy by an average of nine hours per property, streamlining workflows and accelerating retrofit delivery[1][2].

Why Senze is a Game-Changer for Landlords and Social Housing Providers

The UK faces a monumental challenge in retrofitting its aging housing stock to meet climate targets and eliminate fuel poverty. Estimates suggest that achieving net zero in UK homes could cost more than £500 billion[1][2]. Senze’s data-driven approach offers a transformative alternative that can reduce costs significantly while delivering accurate, actionable insights.

David Partridge, co-founder of Senze, highlighted the tool’s potential, saying, “Retrofitting British homes to reach net zero is estimated to cost more than £500bn. But what if we could actually do it much more cheaply? Senze is a genuinely game-changing British technology that will enable the UK to tackle this colossal retrofit challenge at pace and scale.”[1][2]

Tom Fenton, CEO of Senze, noted that social landlords, who manage large legacy housing portfolios, are a key focus for the tool’s deployment. The system’s capability to support strategic asset management decisions, such as buying or selling stock based on energy performance data, adds further value[1].

Key Benefits of Using Senze for Retrofit Projects

• Accurate Real-Time Data: Sensors installed in each room capture live thermal and energy performance, providing a far more precise picture than estimated EPC ratings.
• Cost Savings: By identifying unnecessary or less impactful retrofit measures, Senze helps landlords avoid overspending on works like external wall insulation.
• Energy Bill Reduction: Improved targeting of retrofit actions leads to lower annual energy costs for tenants, supporting efforts to reduce fuel poverty.
• Carbon Emission Cuts: Landlords can meet environmental and regulatory obligations through quantifiable reductions in carbon emissions.
• Time Efficiency: Live data replaces lengthy visual inspections, cutting assessment and consultancy time by an average of nine hours per property.
• Strategic Asset Management: The tool supports informed decisions on housing stock investments and divestments by integrating energy performance analytics.

Addressing Retrofit Challenges with Technology

Traditional retrofit assessments rely heavily on visual inspections and computer-generated models based on standardized assumptions, which can lead to inaccuracies and suboptimal recommendations. Senze’s novel approach transcends these limitations by leveraging IoT sensors and real-time monitoring to collect empirical data from inside each home.

This transformation in retrofit diagnostics is crucial for unlocking energy savings in the social housing sector, where budgets are constrained and the risk of ineffective capital expenditure is high. By providing landlords with reliable, actionable intelligence upfront, Senze ensures money is spent efficiently, maximizing the impact of retrofit investments.

Supporting Government and Sustainability Goals

The introduction of Senze aligns with broader UK government objectives for energy efficiency and carbon reduction in residential buildings. Accurate data and targeted retrofit measures help social landlords and registered providers meet regulatory requirements, including those linked to Energy Performance Certificate improvements and decarbonization targets for 2030 and beyond[3].

Additionally, successful retrofit programs assist landlords in securing funding and attracting investment by demonstrating compliance with Environmental, Social, and Governance (ESG) criteria. Tools like Senze that quantify both cost savings and carbon reductions enhance the credibility of social landlords’ sustainability strategies[3].

Related Technologies in the Retrofit Space

Senze is part of an emerging ecosystem of retrofit tools focusing on optimizing home energy performance with data-driven insights. For instance, Kamma Climate offers a Home Energy Saving Tool that helps landlords and homeowners uncover cost-effective retrofit packages based on unique property data, aiming to increase retrofit uptake and lower emissions[5].

While Kamma’s tool emphasizes customer education and finance solutions to encourage retrofit investment, Senze’s strength lies in delivering precise, sensor-based diagnostics for social landlords managing large property portfolios[1][5].

The Future of Energy-Efficient Housing Retrofits

As the UK and other countries intensify efforts to decarbonize housing stock, data-driven retrofit tools like Senze will play an increasingly vital role. By combining technology, accurate measurements, and strategic insight, these platforms enable targeted, cost-effective upgrades that bring multiple benefits:

• Enhanced tenant comfort and health
• Significant reductions in energy consumption and fuel poverty
• Lower carbon footprint for housing sectors
• Accelerated retrofit delivery timelines
• Optimized investment decisions by landlords

Senze exemplifies how innovation in retrofit assessment can transform challenges into opportunities, supporting landlords to deliver greener, more affordable homes at scale.
