Energy & Cost Savings Proposal

Hayling College

This proposal turns your energy data into a live, transparent financial plan for a full-site LED upgrade - built to reflect how your school actually operates.

Why This Dashboard Matters

Every LED upgrade proposal should come with complete transparency - and a clear explanation of what’s being offered, how it performs, and what it’s worth over time. This interactive dashboard gives you exactly that: real figures based on conservative assumptions, premium fixtures selected for compliance and long-term performance, and calculations you can explore and verify yourself.

Use the scenario planner to test different assumptions. Adjust your energy rates, usage schedules, or operational patterns and see the real-time impact on your financial outcomes. This is how a properly engineered LED upgrade should be presented - practical, flexible, and fully accountable.

If you'd like to walk through any aspect together, our team is here to explain the detail behind every calculation and support your decision-making process.

Key Assumptions & Methodology

This proposal demonstrates how a strategically planned LED lighting upgrade can use your existing energy budget to fully fund both the new LED fittings and their installation, achieving complete budget neutrality whilst delivering substantial long-term benefits.

Conservative Projections

Our calculations use conservative estimates to ensure realistic outcomes. We've based operating hours on minimum school patterns without including potential additional savings from extended day periods, enhanced controls, or future energy price increases.

Premium LED Specification

We've specified higher-efficiency LED solutions that extend whole-life value. With 60,000+ hour lifespans and superior lumen-per-watt performance, these fixtures deliver a stronger return on investment over their operational lifetime when compared to standard fittings.

Flexible Financing

Our financing options allow you to spread the investment over time while maintaining positive cash flow. Adjust the funding term and deposit in the calculator to find the optimal structure for your budget.

🚀 Quick Start Guide

This dashboard calculates your potential savings from upgrading to LED lighting. Use the Scenario Planner (left sidebar) to adjust assumptions and see real-time updates across all metrics.

The Financial Case

The Financial Impact

Cash Flow Neutral or Better from Day One

Your projected energy savings are designed to match or exceed funding costs. By adjusting deposit levels and funding terms, you can tailor the financial profile to suit your strategy - ensuring the upgrade delivers immediate value while modernising your estate.

*Lifetime calculation: 31-year projection using weighted-average methodology. High-consumption areas (classrooms, offices) are weighted proportionally to their energy use, whilst PIR-controlled areas contribute based on their reduced operational hours.

LED Technology Benefits Fixed Information

💡 Extended Lifespan

60,000+ operational hours compared to 10,000 hours for traditional lighting - that's over 25 years of typical school use. All fixtures come with a 5-year manufacturer warranty and a 1-year onsite installer warranty for complete peace of mind.

🎨 Superior Light Quality

CRI 80+ colour rendering ensures natural light appearance, reducing eye strain and improving learning environments.

⚡ Instant Performance

No warm-up time required. Full brightness immediately with no flickering or humming sounds.

🔧 Minimal Maintenance

Virtually maintenance-free for 10+ years, dramatically reducing replacement costs and disruption to classes. With fewer fixtures and only 12 standardised types (down from 15), future procurement and replacement becomes simpler and more cost-effective.

Why "Whole of Life" Beats "Lowest Upfront Cost"

Most LED upgrade projects fall into the same trap: choosing the cheapest possible fittings to tick the "sustainability" box. But in doing so, many schools end up locking in higher long-term costs — paying more in energy bills, maintenance, and replacements for years to come.

That's why we've taken a total cost of ownership approach to your lighting upgrade — selecting products that deliver both immediate savings and sustained value over time.

A Smarter Balance of Cost and Performance

For this project, we've focused on delivering the best long-term value within the practical budget constraints of a state school. The fixtures we've selected offer a strong balance between affordability and durability, providing 60,000+ hours of lifespan — significantly reducing the need for future replacements and lowering maintenance overhead.

This ensures you benefit from high-quality, energy-efficient lighting that cuts running costs year after year, without compromising your upfront budget. It's a smarter investment that supports both operational and sustainability goals in a way that's financially realistic.

Our Quality-First Approach

This is exactly why we:

  • Specify high-quality, efficient fittings that balance upfront affordability with durability and performance — avoiding low-cost, short-life options that cost more in the long run.
  • Include intelligent sensors in key areas such as corridors, toilets, and stairwells — ensuring you maximise savings by reducing wasted energy in areas that are often left lit unnecessarily.
  • Factor in maintenance costs — cutting corners on fittings leads to earlier failures, more disruption, and higher labour costs for replacements.

Smart Control Strategy Maximising Efficiency

Beyond the core LED upgrade, strategic deployment of occupancy sensors transforms your energy profile by ensuring lights operate only when spaces are occupied. The hours shown in the calculations already reflect these intelligent reductions:

This comprehensive approach also avoids future retrofit costs. Installing sensors later - particularly in corridors and circulation areas - would require additional mobilisation costs and cause more disruption. By addressing all control upgrades now, we maximise efficiency whilst minimising long-term costs. And of course using your PIR sensors will extend the life of your LED lights still further.

Funding Options

Self-Funding: If you choose to self-fund this project, payment terms are 40% on order and 60% on completion.
