Tesla Powerwall 2 was it worth it - 2 years on in the UK

Our Tesla Powerwall 2 has been installed for 2 years. I look at the costs to install, the Powerwall's performance and statistic, how we operate it and how much we have saved. Will it pay for itself? I cover any issues and did we make the right decision. Does a Powerwall work in the UK? Will a home battery get a return on investment?

How did I miss that! Thanks to @bonbon who pointed this out.
@15:04 should have been times 24 months, not 48! This means the saving is £36.78 per month. So £57 - £36.78 = £20.22 per month for the cost of the Powerwall! Even better value!
