Tesla Electric UK: What It Means for Powerwall Owners in 2026

Posted by Alicja Kopinska on 10 Apr 2026

TL;DR On 12 March 2026, Ofgem officially granted Tesla a full retail electricity supply licence. Tesla Electric is coming to the UK. Anyone can sign up - you do not need a Tesla car or a Powerwall. But the more Tesla hardware you have, the more the system works in your favour. Powerwall owners can realistically reduce their annual electricity bill by £700 or more, and earn additional income through a Virtual Power Plant - before Tesla Electric has even launched, using tariffs available today.

Can You Put Solar Panels on a Flat Roof? Everything You Need to Know

Posted by Alicja Kopinska on 03 Apr 2026

TL;DR:
Yes, you can install solar panels on a flat roof. Modern ballasted mounting systems are non-penetrative, so there is no drilling through your roof membrane. Panels are tilted at around 10 degrees and can face south or be mounted east/west depending on your roof shape. No planning permission is needed for most properties. A south-facing system in southern England generates around 900 kWh per kWp per year. Costs start at roughly £1,200 to £1,800 per kWp for domestic systems.

Do Solar Panels Reduce Your Electricity Bill in the UK? 2026 Guide

Posted by Alicja Kopinska on 20 Mar 2026

Why electricity bills keep rising in the UK

Electricity bills in the UK continue to rise because the market is still heavily influenced by global energy prices, particularly gas. Even though we generate a growing share of electricity from renewables, gas often sets the wholesale price of electricity. When global supply is disrupted or demand increases, prices rise across the board. This has been seen repeatedly in recent years, and it means households remain exposed to factors completely outside their control. As long as the UK relies on gas as a core part of its energy mix, price volatility is likely to remain.

Posted by Charlie McGibbon on 08 May 2024

For those who have their finger on the pulse of the solar energy market, it's becoming obvious that there is an increasing shift towards the manufacture and use of n-type solar from p-type panels in both commercial and domestic settings, to the point where the former now dominate. But why has this shift come about, and more fundamentally what is the difference between the two?
