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.

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.

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.

TL;DR
UK energy prices are under renewed pressure as gas and oil markets react to Middle East tensions, and that volatility is exactly what tends to push both electricity bills and solar installation prices higher over time. If solar is already on your radar, waiting for “certainty” can backfire, because when everyone jumps at once, installer bottlenecks and supply chain pressure usually drive solar costs up.

TL;DR
Solar is not just about lowering your electricity bill. It is a long-term hedge that reduces your household’s exposure to unpredictable energy prices, similar to holding gold for protection rather than speculation.

TL;DR
If you are planning solar panels or a battery, the DNO application is not just admin, it is one of the most important parts of the project because it determines what size system you are allowed to install, how much you can export, whether you might face connection costs, and how your payback stacks up. This guide explains what a DNO application is in the UK, what your Distribution Network Operator looks at, and why local grid capacity can feel first come first served, so you can avoid expensive design mistakes later. 

The UK’s grid connection reforms are fundamentally changing how solar and battery storage projects get financed and built. Experts say the shifts, designed to tackle one of Europe’s longest connection queues, are creating both opportunities and headaches for developers, with knock-on effects likely to influence renewable markets across the continent.

“I can’t buy solar, I won’t be in this building long enough to see the returns.”  

TL;DR

Winter is when a home battery should deliver the biggest savings because electricity is often priciest and solar generation is lowest. But cold temperatures can limit charging and power if a battery cannot manage its own temperature. Look for strong thermal management, outdoor-ready weatherproofing with a suitable IP rating, and an installer who sets your system up to reliably off-peak charge.

What Is the Warm Homes Plan? Do You Qualify?

The Warm Homes Plan is the UK government’s largest ever programme aimed at upgrading existing homes to make them cheaper to run, more energy efficient, and less reliant on fossil fuels.
