The UK market in three points

Britain’s residential market runs on smart tariffs: the Smart Export Guarantee pays export rates that differ by a factor of ten between suppliers, and agile-style dynamic tariffs turn a home battery from a comfort into an income strategy — charge cheap overnight, discharge into the evening peak. MCS certification is not bureaucracy for its own sake: it underpins insurance, warranties and SEG eligibility, and your DNO notification (G98/G99) belongs on the installer’s checklist, not yours. Our editorial advice: pick your tariff strategy before sizing anything, and treat any quote that does not line-item scaffolding, registration and monitoring as unfinished.

What to check before you buy

Four things decide your project: ① the real all-in price — scaffolding, registration and monitoring belong inside the quote; ② the written warranty — years, cycles, and who responds locally if your installer vanishes; ③ after-sale service — ask for response times and European parts stock; ④ your consumption curve — your smart meter app has it, and it should size the battery. Our free tools help with the first three.
