The paperwork for a Bedford battery goes to a company most households never deal with directly. Your supplier sends the bills, but the cables that reach your house belong to the network operator, and in central Bedford that is UK Power Networks. Every battery that can feed power back into those cables has to be reported to it, and a large one has to be approved before anyone picks up a drill. This guide explains which network Bedford is on, how G98 and G99 work, what UK Power Networks approves automatically and what a battery really does when the power goes off. For where a unit fits in Bedford’s flats and houses, see our page on battery storage in Bedford.
None of this is something you fill in yourself. The installer handles it. But knowing the steps helps you read a quote, judge a timetable and ask the right question if a design comes back bigger or smaller than you expected.
Which network Bedford is on
UK Power Networks’ own licence-boundary data places central Bedford in its Eastern Power Networks area. Its history page says its Eastern predecessor managed the cables and lines in most of Bedfordshire, and the company runs a postcode area checker for anyone unsure. That is worth using if you live on the edge of the borough: on NESO’s boundaries, the nearest other licence area, National Grid’s East Midlands network, is about 7.8 km from the town-centre point. For any single address, the checker settles it, and your installer confirms it before applying.
The 16 A line: G98 or G99
The rule that matters is a single number. Under the Energy Networks Association’s EREC G98, type-tested equipment rated up to and including 16 A per phase, which is 3.68 kW on a normal single-phase house supply, is notified to the operator before commissioning or no later than 28 days after it. Anything above that line needs a G99 application approved before work starts. A 4 kW inverter, at 17.39 A, is just over it.
What counts is the inverter rating, not the battery’s storage capacity. A 10 kWh battery behind a 3.68 kW inverter is a G98 job; a 5 kWh battery behind a 5 kW inverter is not. If you already have panels, the existing inverter and the new one are added together.
What UK Power Networks approves automatically
UK Power Networks says it automatically approves applications where the maximum export, after any export limitation scheme, is under 5 kW. Export limitation means the system is set up so that it never sends more than a set amount to the grid, whatever its inverters could produce. For a Bedford house whose evening use justifies a larger inverter, a limit below 5 kW can be the difference between automatic approval and a longer wait. The design should say plainly whether a limit is applied and at what level.
Approved installers file the forms through UK Power Networks’ Smart Connect portal, which handles G98 and G99 applications for solar PV and battery storage. For a house whose supply can take the new equipment, UK Power Networks says the installer simply notifies it within 28 days of installation; where G99 applies, the approval still comes first.
When the supply itself needs work
Sometimes the survey finds that the incoming supply is not sufficient for the additional load. UK Power Networks says it may then need to upgrade the supply first, and that the cost and timing of each project vary. If no upgrade is needed, there is nothing for you to pay it. The survey checks the main fuse and the consumer unit before a design is fixed, and in Bedford’s older housing, where ONS puts the median EPC score for existing houses at 60 in Castle & Kingsway and 62 in Harpur, it is also the moment to ask whether insulation belongs in the same conversation.
Power cuts, plainly
A standard grid-tied battery shuts down when the grid does, even when it is full. That is deliberate: it stops the system feeding power into lines engineers may be working on. So in a power cut, a Bedford home with a standard battery goes dark like its neighbours.
How often does that happen? Ofgem’s 2024/25 figures for the whole Eastern Power Networks area show about 44.6 supply interruptions per 100 customers and about 32.5 minutes lost per customer over the year, counting planned and unplanned work. Those are averages across a large licence area, not a forecast for your street, and on their own they are rarely a reason to buy a battery.
If keeping a few circuits live matters to you, backup can be designed in, with extra switching and wiring, and priced as its own line. Winter limits it: PVGIS puts a 4 kWp south-facing Bedford array at about 141 kWh in December, roughly 4.5 kWh a day (our arithmetic), so a backup battery in a December cut runs on what it held beforehand.
Flats, landlords and the meter room
In the Bedford built-up area, flats, maisonettes and apartments make up 28.9% of households and 25.2% of households rent privately. In those homes the grid steps above come second: the freeholder’s written consent, and the landlord’s for tenants, comes first, because the meter, the cable route and any shared supply belong to the building.
Reading a quote with this in mind
A quote should state the inverter rating, whether the job is G98 or G99, any export limit and whether backup is included. Our guide to solar battery storage explained covers how the parts fit together, and what size home battery you need helps you check the capacity. For the roof, see solar panels in Bedford, and for the county’s schemes and planning, the Bedfordshire solar panels hub.
