📊 CASE STUDY: How a Business Spending £2,500/Month on Electricity Can Save £1M+ With Solar PV
If your business is spending around £2,500/month (£30,000/year) on electricity, this will be one of the most eye-opening case studies you’ll read this year.
Here’s the reality…
Energy usage won’t increase much.
Energy prices absolutely will.
And that’s the biggest financial risk most businesses overlook.
🔍 Energy Usage Forecast
Most commercial premises (warehouses, retail, light industrial, offices) only see ±10% usage change over 10 years.
So your consumption stays roughly the same.
But your cost doesn’t…
🔥 What Happens If Prices Keep Rising?
Even using a low assumption of 5% annual increases:
Year 1: £30,000
Year 10: £48,886
Year 20: £79,788
Year 25: £102,050 per year
Total cost over 25 years if you do nothing: £1.51 million.
This is the real threat to UK businesses.
