A buying guide built on usable capacity, round-trip efficiency, warranty terms, and real installed cost — not manufacturer marketing.

Octopus Energy unveiled the Nook Cube and Nook Colossus at its Energy Tech Summit on 22 June 2026 — becoming the first major British energy supplier to launch its own home battery range. The Cube is plug-in and needs no installation, opening battery storage to renters for the first time. Both go on sale in 2027 with native Kraken smart-tariff integration built in.

Most UK solar owners use only 30% of what their panels generate — the rest is exported at a fraction of the import price. This guide sets out the practical, ranked ways to raise that figure: shifting appliance use into daylight hours, adding a solar diverter for hot water, charging an EV from your own panels, and adding battery storage to bank the midday surplus for evening use. Includes the Energy Saving Trust's baseline self-consumption figures and a step-by-step order to tackle them in.

Repurposed EV batteries are 30-40% cheaper than new cells and cut carbon emissions sharply, but a UK government-commissioned safety study found experts split on whether they can ever be safely deployed in homes. Here's what second-life EV battery storage actually is, where the UK market stands today, and why homeowners can't buy one yet.

Home battery storage is often lumped in with headline lithium-ion fire statistics that are almost entirely e-bikes, phones and EVs — not stationary storage. Here's what UK data on battery-bank fires actually shows, why chemistry and placement rules matter, and how to buy with confidence.

On 8 and 9 October 2026 the government granted development consent to Green Hill Solar Farm and the Steeple Renewables Project, together roughly 950MW of solar with battery storage. Here is what was approved, how it fits the 2030 solar target, and what it does and doesn't mean for UK homeowners.

With electricity costing 24.67p per kWh under the Ofgem Q2 2026 price cap, cutting what you use and generating your own can save hundreds of pounds a year. This guide walks through every proven measure, from quick wins like LED lighting to bigger investments like solar panels and battery storage.

Sodium-ion is emerging as a lithium-free alternative for home battery storage — cheaper raw materials, better cold-weather performance, and no cobalt or nickel. But UK residential products are still niche in 2026. This guide explains how sodium-ion compares to the LFP batteries most homes buy today, who is actually selling sodium-ion batteries in Britain right now, and an honest verdict on whether to wait.

A 5kW solar panel system is now one of the most popular choices for UK families. Covering 12–14 panels, it generates around 4,000–4,500 kWh per year — enough to cover most of a typical 3–4 bedroom home's electricity use. This guide walks through 2026 installed costs, realistic bill savings, payback periods with and without battery storage, and whether 5kW is the right size for your home.

Commercial battery storage lets UK businesses cut energy bills, avoid peak-demand charges, and earn revenue from grid services. This guide covers system sizes from 50 kWh to 1 MWh, AC vs DC coupling, key suppliers, the Balancing Mechanism, capital allowances, fire safety requirements, and how to model a realistic 5–8 year payback.

You don't need your own roof or your own battery to benefit from stored solar — that's the idea behind community battery storage, and the UK government opened a call for evidence on it in June 2026. Here's what a community battery actually is, who it's aimed at, what real UK schemes have already shown, and what to do instead if you can install your own battery today.

EcoFlow's Stream 5000 launched in the UK on 21 August 2026 — a stackable 5kWh home battery pitched as a middle ground between a plug-in balcony solar kit and a full MCS-installed battery storage system. Here's what it actually offers, what it costs, and who it genuinely suits.
