Battery storage in East Grinstead

What decides a battery job in East Grinstead

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 East Grinstead.

Behind a timber frame

PAS 63100:2024 — the fire-safety specification home batteries have been installed to since April 2026 — wants a location out of the living space with the clearances and detection around it. A timber-framed High Street house rarely offers that in the house itself, and a listed interior adds the consent question on where the stack sits and how the cables run. The positions that work are the cellar where there is one, an outbuilding, or a later rear addition; what we will not do is wedge a stack into a cupboard off the hall and call it compliant.

Where the house is listed we put a drawing to the conservation officer first, which costs you nothing and settles it either way. Solar panels in East Grinstead is the roof side of the same survey.

On the later streets

Outside the conservation area the job is the Mid Sussex standard: a garage or utility wall, a short run to the board, UK Power Networks notified, and a size that comes from your half-hourly consumption or your bills rather than from a price list. If the sums say a smaller battery, or none, that is the quote you get. The county picture is on the battery storage page; Haywards Heath and Burgess Hill are the neighbouring pages on the same run.

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 East Grinstead ask before they book

“The house is listed — is a battery even possible?”

Often, yes. The kit is indoors and the outside of the building is untouched; what can need consent is the position of the stack and the route of the cables. We ask the conservation officer with a drawing before we quote rather than discover it afterwards.

“We are right on the edge of town — which council are we even under?”

Whichever the address says. East Grinstead sits where four counties meet, so we read the council from the postcode and the network operator from the MPAN on your bill, and the quote names both.

Questions we get asked in East Grinstead

Who receives the notification for a battery in RH19?

UK Power Networks — group J on the 18 October 2026 lookup. An inverter up to 16 amps per phase is notified under G98 after it is fitted; anything larger is applied for under G99 before it is energised. We make both.

Can a battery go in an East Grinstead High Street house?

Sometimes. It needs a position that meets PAS 63100 — a dry cellar, an outbuilding or a later rear addition usually — and on a listed house the position and the cable runs are put to the conservation officer first. The survey says which your house has before any size is named.
