Financial Comparison: Solar vs Pension Investment

Phil Ogden financial advisor solar investment is it worth it

Phil Ogden, an independent financial advisor, recently analysed the return on a £17,000 investment in solar panels on his own home, looking at the investment over 20 years compared to investing the same amount in a pension.

“Even with basic-rate tax relief, the pension didn’t match the total return from solar. In fact, if you reinvest your energy savings of £220.67/month into your pension (boosted to £275.84/month with tax relief), you could generate over £130,000 in pension growth over 20 years.

That’s a remarkable return from a solar installation—especially when you consider that you’re also saving on bills the whole time.“

Phil’s example highlights the wealth-building potential of solar energy – not just as an environmental choice, but as a smart financial move.
