Northern Powergrid Connection Guide: Solar, Batteries & EV Chargers in Doncaster (2026)

If you are fitting solar panels, a home battery or an EV charger anywhere around Doncaster in 2026, there is one piece of paperwork almost nobody talks about until it matters: the connection to your local electricity network. Every generation or storage device you bolt onto your home has to be registered with, or approved by, the company that owns the wires in your street — your Distribution Network Operator, or DNO. Get this wrong and you can end up with an installation that is technically illegal, uninsurable, and ineligible for export payments. Get it right and it happens quietly in the background while you enjoy cheaper bills.

At Amppro Electrical we are based at Armthorpe in DN3, and we handle these connection notifications week in, week out across South Yorkshire, north Nottinghamshire, north Lincolnshire and north-east Derbyshire. This guide explains, in plain British English, who your DNO is, the difference between G98 and G99, and how the whole process fits together in 2026.

Who is your DNO — Northern Powergrid or NGED?

This is the single most common point of confusion, because "who supplies my electricity" and "who owns the network" are two completely different things. Your supplier is who you pay (Octopus, E.ON, British Gas and so on). Your DNO is the company that physically owns the cables, substations and poles — and it is set purely by geography, not by choice.

For most of our patch, your DNO is Northern Powergrid (Yorkshire):

• **Doncaster and the whole borough** — Bessacarr, Cantley, Armthorpe, Bentley, Askern, Thorne and the rest.
• **South Yorkshire** generally — Sheffield, Rotherham, Barnsley, Mexborough, Conisbrough, Maltby, Rossington and Tickhill.
• Much of the **East Riding** and the towns north towards Selby.

But there is a hard boundary running just south and east of Doncaster, and once you cross it your DNO changes to National Grid Electricity Distribution (NGED, East Midlands) — the network formerly known as Western Power Distribution:

• **Nottinghamshire** — Worksop, Retford, Harworth and Mansfield.
• **Derbyshire** — Chesterfield and Bolsover.
• Much of **Lincolnshire**, including large parts of the Gainsborough area.

This matters because the two operators use different online portals, have slightly different approval timescales, and quote different figures for any reinforcement work. When we survey a job in [Worksop](/solar-panels-worksop) or [Retford](/solar-panels-retford), we lodge the connection with NGED; a few miles north in [Doncaster](/solar-panels-doncaster) or [Conisbrough](/solar-panels-conisbrough), the very same paperwork goes to Northern Powergrid. Scunthorpe and the north Lincolnshire towns sit in NGED territory too. If you are unsure, the quickest check is to look up your postcode on the Energy Networks Association "Who is my network operator" tool — or simply ask us during the survey.

G98 and G99: notify or apply?

Under the industry connection rules (Engineering Recommendations G98 and G99), every piece of generation or storage kit falls into one of two camps depending on its size:

• **G98 — "connect and notify".** For small single-phase systems up to **3.68kW per phase** (16 amps), you are allowed to install first and notify the DNO afterwards, usually within 28 days. Most modest domestic solar arrays and many home batteries sit here.
• **G99 — "apply and wait".** Anything larger than 3.68kW per phase needs the DNO's **prior approval before** you switch it on. The operator assesses whether the local network can absorb the extra generation. Approval typically takes a few weeks, occasionally longer if the substation is already busy.

A few practical points people get caught out by. First, it is the inverter output that counts, not the panel wattage — a 4.5kW array on a 3.68kW inverter can still be notified under G98. Second, batteries and EV chargers can trigger a notification too, not just solar. A large battery inverter or a load-managed charger may need registering even if you have no panels. Third, if you already have solar and are adding a battery, the combined system may tip you over the G98 threshold and into G99 territory. We assess all of this before we quote, so there are never any surprises.

The connection process, step by step

For a typical Doncaster home the journey looks like this:

1. Survey and design. We check your roof, consumer unit, main fuse and earthing arrangement, and design a system that suits both your usage and your DNO's rules. 2. Notification or application. For a G98 job we install and notify. For a G99 job we submit the application and wait for the operator's written approval before commissioning. 3. Installation. Our MCS-certified team fits the kit — solar, battery, charger or a combination. 4. Commissioning and handover. We test, issue your certificates and, for solar, your MCS certificate — the golden ticket for export payments. 5. DNO sign-off. We close out the notification so your system is fully legitimate on the network.

For MCS-registered installers this is routine, and for the great majority of homes across [Rotherham](/solar-panels-rotherham), [Mexborough](/solar-panels-mexborough) and [Barnsley](/solar-panels-barnsley) it never involves paying the DNO a penny. Reinforcement charges only appear on the rare occasion the local network genuinely needs upgrading.

What solar actually generates around Doncaster

South Yorkshire is sunnier than its reputation suggests. The area sees roughly 1,350–1,450 hours of sunshine a year, and the flat eastern terrain around Doncaster, Thorne and the Lincolnshire border means minimal horizon shading. In 2026 the standard domestic panel is around 440W, so a typical 4kW system generates about 3,300–3,800 kWh a year here — enough to cover a large slice of an average household's electricity.

Honest 2026 price ranges, supply-and-fit, look like this:

• **3kW system:** £5,000–£6,000
• **4kW system:** £6,500–£8,500
• **5kW system:** £8,000–£10,000
• **6kW system with battery:** £11,000–£14,000
• **Battery alone:** 5kWh £3,500–£4,500; 10kWh £5,500–£7,500
• **7kW EV charger:** £800–£1,200

Grants and VAT in 2026 — the honest version

There is a lot of noise online about "free solar", so let us be straight with you.

• **0% VAT** applies to domestic solar, batteries (including standalone retrofits) and associated electrical work until **31 March 2027**. After that it rises to **5%**. You should never see VAT added to a qualifying residential quote — it is already zero-rated.
• **There is no general "free solar" scheme.** Offers that promise free panels to any homeowner are misleading. Fully funded solar only exists through tightly targeted, benefit- or income-gated schemes.
• **ECO4** and the **Great British Insulation Scheme** closed to new applications in spring 2026 and were always restricted to low-income households, qualifying benefits and lower EPC ratings. Most owner-occupiers never qualified.
• The government's **Warm Homes Plan** (including the council-run Warm Homes Local Grant) is the successor, and it too is eligibility- and council-gated — not an open offer.
• The **EV chargepoint grant** rose from £350 to **£500 per socket on 1 April 2026**, but it remains restricted to people living in **flats or rental properties, plus landlords** — standard homeowners have not qualified since 2022, and an OZEV-authorised installer is required.

For nearly all Doncaster homeowners, the real financial case is 0% VAT plus the Smart Export Guarantee (SEG): with an MCS-certified install you can be paid for the electricity you export. SEG rates vary widely by supplier in 2026 — from around 4p to 16p per kWh, with Octopus and E.ON among the more competitive — so it pays to shop around rather than accept your existing supplier's default. We only quote figures we can stand behind; if a claim sounds too good to be true, it usually is.

Local jobs, from Armthorpe to the county line

Because we are based in Armthorpe rather than driving up from a distant depot, we know the housing stock and the network quirks street by street. The Victorian terraces of Hexthorpe and Balby, the 1930s semis across Intake and Wheatley, the post-war estates in Cantley, and the newer developments around Lakeside and Bessacarr each throw up their own consumer-unit and earthing considerations. Doncaster Council declared a climate emergency in 2019 with a 2040 net-zero target, and demand for home energy upgrades keeps climbing right across the borough.

Cross into Northern Powergrid's neighbouring towns and the same expertise applies in [Thorne](/solar-panels-thorne), [Tickhill](/solar-panels-tickhill) and out towards [Armthorpe](/ev-charger-installation-armthorpe). And when the job sits in NGED country — [Worksop](/battery-storage-worksop), Retford or Chesterfield — we simply switch portals. Whether it is a fresh solar array, a battery retrofit, an EV charger, an [EICR](/eicr-cost/), a [consumer unit upgrade](/consumer-unit-upgrades/) or a full connection application, one local team handles the lot.
