Historical Context:
UK electricity prices rose at 3.8% annually (2010-2021). Conservative default of 3.0% models compound savings growth as energy prices increase over time.

LED Lighting Upgrade Dashboard
Energy & Cost Savings Proposal
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 your existing energy budget can fully fund a comprehensive LED upgrade,
including both premium fittings and professional installation, while achieving immediate positive cash flow.
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 or enhanced controls.
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 lease term and deposit in the calculator to find the optimal structure for your budget.
🚀 Quick Start Guide

Here's What Most Schools Don't Realise...
You're already paying for a full LED lighting upgrade — you're just not getting one.
Every month, St Mary's School spends approximately £815
on lighting energy — much of it wasted on outdated fluorescent tubes. But what if that spend could be
redirected into a cost-neutral upgrade that slashes your energy use and your
carbon emissions from day one?
The Financial Reality:
▸Your current energy spend covers the monthly payments
▸As a VAT-registered school, reclaim 20% of the total project cost
▸Immediate positive cash flow - save from month one
▸No capital outlay required with our managed funding
In short: Your energy company pays. The government helps. You save.
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.
Our specified fixtures deliver 60,000+ hours of operational life – that's
over 45 years
of typical school use without replacement. This isn't just about energy savings; it's about creating
lasting value for your school.
Beyond Energy Savings: The Complete Value Picture
Enhanced Learning Environment
Premium, UGR ≤ 19 compliant LED lighting transforms classrooms with superior light quality – better colour rendering (CRI 80+),
reduced flicker, and consistent illumination levels. Students and
staff benefit from consistent, comfortable lighting that supports wellbeing and productivity. Research shows that proper lighting improves student
concentration, reduces eye strain, and can even boost academic performance by up to 15%.
Financial Intelligence
With immediate positive cash flow from day one, you're not waiting years to see returns.
The £7,551 annual savings
can be redirected to educational resources, technology upgrades, or facility improvements.
Over the 45-year fixture lifespan,
that's over £355,000
returned to your educational budget if you self-fund.
Operational Excellence
Forget the constant disruption of failed tubes and emergency call-outs. Our specified fixtures virtually
eliminate maintenance for the next decade. That means no more:
Classes interrupted by maintenance work
Budget surprises from emergency repairs
Staff time wasted reporting and managing lighting failures
Health & safety concerns from flickering or failed lights
Environmental Leadership
By cutting 30,204 kWh annually
(77% reduction),
St Mary's School joins the vanguard of educational institutions taking climate action seriously.
This visible commitment to sustainability becomes a teaching tool, demonstrating to students that
environmental responsibility and financial prudence go hand-in-hand.

✓ End-to-End Project Management - From initial survey to final commissioning, we handle everything
The Hidden Costs of "Cheap" LED
Beware of contractors offering rock-bottom prices. Low-quality LEDs often deliver only 20,000-30,000 hours,
use inefficient drivers that waste energy, and suffer from colour shift and lumen depreciation within 2-3 years.
You'll end up replacing them twice while our fixtures are still performing at 90% output.
What is UGR ≤ 19 and Why Does It Matter?
Educational Research Findings
Studies consistently show that lighting quality affects how students learn and feel in class.
International standards (EN 12464-1, SLL Lighting Guide 5) recommend a
Unified Glare Rating (UGR) ≤ 19 for classrooms to avoid discomfort glare.
When classrooms meet this benchmark, students experience less eye strain, fewer headaches,
and improved ability to concentrate for extended periods.
Research has linked low-glare, well-designed lighting to measurable
academic benefits: faster and more accurate reading, better comprehension, and calmer
behaviour. Teachers also report less visual fatigue and more effective classroom management
when lighting conditions are comfortable and consistent.
By contrast, non-UGR-compliant lighting – such as bare LED fittings –
has been associated with headaches, visual discomfort, reduced clarity on boards and screens,
and heightened distraction. Poor glare control can undermine both attendance and attainment.
Our Commitment: Unifi.id exclusively specifies UGR-compliant lighting fixtures
in all educational environments where they are required, ensuring optimal learning conditions
whilst delivering energy savings. We never compromise on visual comfort for the sake of cost reduction.
