Battery storage in Lewes

What decides a battery job in Lewes

Where the stack can go, what the board and the supply will take, and how much the house actually uses after dark. These are the local facts behind those three questions in Lewes.

Adding a battery to the panels Lewes already has

The survey starts at the wall where the inverter already is: its make and age, its paperwork, what the array actually produces, and whether that inverter can take a battery directly or needs a battery inverter alongside it — a cleaner job than it sounds. Then the board, which on a house whose panels went in some years ago is sometimes the real work. Then the position under PAS 63100, which in a Lewes town house is usually a dry cellar or a utility. The new inverter is notified to UK Power Networks and the handover pack covers both halves of the system; we hold our own quote against the Solar Together prices, which remain a fair yardstick for anyone’s.

Adding a battery to panels you already have in East Sussex is the longer read; solar panels in Lewes is the roof side.

Cellars, flint and the listed question

The historic core is flint and tile with a great many listed houses, and a listed interior is where a battery can need consent even though the outside of the building is untouched: the position of the stack and the route of the cables are the two things the conservation officer looks at, so a drawing goes to the National Park Authority before we quote. Where the house is not listed, the cellar or the utility is agreed in a minute and the work is in the sizing — half-hourly consumption or bills, never a price list. The county picture is on the battery storage page; the East Sussex edge covers Peacehaven and the coast, and Brighton & Hove is the next page west.

What a battery changes on the bill

Without storage a typical home uses somewhere around half of what its panels make and exports the rest; the Smart Export Guarantee pays for those exported units, but at less than you pay to buy them back in the evening. A battery sized to the evening load keeps most of that surplus at home. The size is the whole question, which is why we read half-hourly consumption from the meter where it will give it and the bills where it will not, and why the calculator asks for your bill before it says a number.

Two things people in Lewes ask before they book

“Our panels went in under Solar Together — will a battery work with them?”

In most cases. The survey reads the existing inverter first: some take a battery directly, others need a battery inverter alongside, and either is a tidy job. What we check before promising anything is the board and the paperwork the original installation left.

“The house is listed — does a battery need consent?”

Possibly, for the position and the cable runs rather than the kit. We put a drawing to the National Park Authority’s conservation officer before we quote; that costs you nothing and settles it either way.

Questions we get asked in Lewes

Who receives the notification for a battery in Lewes?

UK Power Networks — BN7 and BN8 are group J on the 18 October 2026 lookup. G98 for an inverter up to 16 amps per phase, a G99 application above that, both made by us before the system is energised.

Can a battery go in the cellar of a Lewes town house?

Often, yes. A dry, ventilated cellar suits PAS 63100 on location and clearances; the survey checks the detection, the cable route to the board and, on a listed house, whether consent is needed for either.
