The short answer for Norfolk: a 4kW south-facing system in Norfolk generates about 4,130 kWh a year on the EU's PVGIS model — about 1% more than London. Installed prices for that size run roughly £6,600–£7,800 on the UK government's 2025/26 cost data, and at October–December 2026 Eastern electricity prices (26.61p/kWh) it is worth roughly £700 a year without a battery, or £900 if a battery lets you use most of it yourself.
Norfolk is a county of detached houses, and a lot of them are off the gas grid: 17% of households heat with oil alone, against 4% across England and Wales. That shapes solar here. Roofs are often big enough for 4–6kW, and many owners are pricing panels alongside a heat pump rather than on their own.
How much a solar panel system generates in Norfolk
The table uses the European Commission's PVGIS tool for Norwich: crystalline panels at a 35° pitch, with PVGIS's standard 14% allowance for system losses and the local horizon. Your installer's MCS estimate will differ a little because MCS uses its own irradiance tables and your actual pitch and shading, but the gap between places and orientations is what matters here.
| Roof faces | Per kW | 3kW system | 4kW system | 6kW system |
|---|---|---|---|---|
| South | 1,032 kWh | 3,100 kWh | 4,130 kWh | 6,190 kWh |
| East | 819 kWh | 2,460 kWh | 3,280 kWh | 4,910 kWh |
| West | 796 kWh | 2,390 kWh | 3,180 kWh | 4,780 kWh |
Annual output, PVGIS 5.3 (SARAH3 satellite data, 2005–2023) for Norwich, fetched 30 October 2026. Actual output varies year to year.
Of the 25 areas we cover, Norfolk ranks eighth for south-facing yield (Dorset is highest at 1,126 kWh per kW, Glasgow lowest at 853). The seasons matter as much as the location: in December a 4kW system here makes about 140 kWh for the whole month, against 495 kWh in June — which is why a battery is mostly a summer and shoulder-season tool, and why nobody should promise you winter bills near zero.
The figures use Norwich. The flat Norfolk landscape means hills rarely shade a roof; trees, chimneys and outbuildings are the usual culprits, so ask the surveyor for a shading check. East- and west-facing roofs make about four-fifths of a south-facing one. Winter output is low everywhere in Norfolk, so if you heat with oil or a heat pump, don't expect panels to cover winter heating.
What solar costs and saves in Norfolk
There is no separate "Norfolk price" for solar — installers price by system size, roof and access — so the fairest benchmark is the government's own cost series. Across domestic installations registered with MCS between April 2025 and March 2026, the average installed cost was £1,955 per kW for systems up to 4kW and £1,645 per kW for 4–10kW, VAT included and batteries excluded.
| System | Output in Norfolk | Typical installed price | Year-one value, no battery | Simple payback |
|---|---|---|---|---|
| 3kW | 3,100 kWh | £4,900–£5,900 | £600 | 9–11 years |
| 4kW | 4,130 kWh | £6,600–£7,800 | £700 | 9–11 years |
| 6kW | 6,190 kWh | £9,900–£11,700 | £1,100 | 9–11 years |
Price range: DESNZ Solar PV cost data (published 28 May 2026), each size priced between the 4–10kW average (£1,645/kW) and the up-to-4kW average (£1,955/kW); bigger systems tend towards the lower figure per kW. Value: south-facing PVGIS output, 40% used in the home at the Eastern price-cap unit rate of 26.61p/kWh (1 October to 31 December 2026), the rest exported at 12p/kWh (the 12p rate several large suppliers pay their own import customers in September 2026). Payback ignores panel degradation, future price changes and inverter replacement.
Two things move those numbers more than anything about Norfolk itself. First, how much you use yourself: every unit you use saves 26.61p, every unit you export earns only what your export tariff pays — 12p in this illustration. Our illustration assumes you use 40% without a battery; with a battery taking that to around 70%, the same 4kW system is worth about £900 a year — but the battery adds several thousand pounds, so price it as its own line and judge it on its own payback (battery storage guide). Second, the export tariff: rates are set by suppliers, not Ofgem, and range widely — see the solar payback guide for current examples.
VAT on solar panels and batteries installed in homes is 0% until 31 March 2027 (how the relief works), so a quote that adds 20% VAT to a domestic install is wrong.
Solar Together Norfolk
Norfolk's councils run the Solar Together group-buying scheme with iChoosr, now called Switch Together. Norwich City Council says it runs "seasonally (4 times per year)" (Norwich City Council). The latest round we found, in King's Lynn and West Norfolk, took registrations until 25 September 2026 (West Norfolk council); Broadland and South Norfolk run their own sign-up pages (Broadland and South Norfolk). On 30 October 2026 the operator's partner list showed no open Norfolk round (Switch Together partners), so check your district's page for the next one.
Norfolk homes and what they mean for your roof
Census 2021 counted 404,342 households in Norfolk: 29.6% semi-detached, 18.1% terraced, 38.7% detached and 13.0% flats or maisonettes, with 65.0% owner-occupied and 18.5% privately rented (England and Wales: 61.6% owned).
Detached houses are the largest group in Norfolk, at almost four in ten homes. Bungalows have a lot of roof for their floor area, and low eaves make scaffolding simpler, so they are often good solar roofs. A detached house or bungalow with a clear south, east or west slope can usually take a bigger system than a semi: ask for quotes at more than one size and compare the price per kW.
About 70,000 Norfolk households heat with oil only, and only 57% use mains gas alone. Solar doesn't replace an oil boiler, but if you are moving to a heat pump, panels and a heat pump work well together. See the off-gas heat pump guide and the Boiler Upgrade Scheme before you size the panels. On the coast, ask what mounting and fixings the installer uses for salt air.
Planning permission in Norfolk
For houses in England, roof-mounted solar is permitted development — no planning application — as long as the panels stand no more than 20cm proud of the roof slope and don't rise above the highest part of the roof. The main exceptions are listed buildings (which need listed building consent), panels mounted on a wall that faces a road in a conservation area, and properties where the council has removed permitted development rights with an Article 4 direction. Blocks of flats have their own, similar permitted development rules, but panels on a shared roof still need the freeholder's consent. The rules were last amended on 27 August 2026.
Inside the Broads, the Broads Authority is the planning authority for all land and buildings inside its area, not your district council (Broads Authority). The Broads has the status of a national park (Broads Authority), so check with the Authority before fitting panels on a listed building, a building in a conservation area, a flat roof or the ground: on a flat roof anywhere in the Broads you must first ask the Authority whether it needs to approve how the panels will look (GPDO Part 14, A.2(ba)). Elsewhere your district council decides.
In Norwich, the city council lists 17 conservation areas (Norwich City Council). Some streets also have Article 4 directions that remove permitted development rights: Bracondale, Bishopgate, Calvert Street and parts of Heigham Grove (Article 4 directions). If you live there, read the notice for your street before you get a quote.
Connecting to the grid: UK Power Networks (Eastern)
Norfolk's local electricity network is run by UK Power Networks in its Eastern licence area. Your installer notifies or applies to UK Power Networks for the connection; your electricity supplier is a separate company. Rural parts of the county sit at the end of long lines, and bigger systems, or panels plus a heat pump and battery, are more likely to need G99 approval or an export limit, so ask early whether your design needs one.
For a typical home system the installer handles this. A single-phase installation up to 3.68kW of inverter capacity (16 amps per phase) is connected under the G98 process and the network operator is notified within 28 days of commissioning. Anything larger — including a bigger system, or panels plus a battery whose combined inverter capacity passes that limit — goes through G99, which needs the network operator's approval before installation and can add weeks. Ask your installer which route your design needs and whether an export limit is being applied.

Questions from Norfolk homeowners
How much do solar panels cost in Norwich and Norfolk?
A typical 4kW system costs roughly £6,600–£7,800 on the government's 2025/26 installation cost data, VAT-free on a home. Bigger systems for detached houses and bungalows cost less per kW. The cost table above uses Norwich's output and Eastern electricity prices.
Is Norfolk good for solar panels?
Yes. On PVGIS data a 4kW south-facing system in Norwich makes about 4,130 kWh a year, more than London. East- and west-facing roofs make about four-fifths of that.
I heat my Norfolk home with oil. Should I get solar panels or a heat pump first?
Solar panels cut your electricity bill, not your oil bill. If you plan to replace the oil boiler with a heat pump, get the heat pump survey first or at the same time, so the solar system is sized for the extra electricity the heat pump will use.
Do I need planning permission for solar panels in the Broads?
Ask the Broads Authority, which is the planning authority there. Panels on the pitched roof of an ordinary house are usually permitted development, but flat roofs, listed buildings, conservation areas and ground-mounted panels need checking with the Authority first.
Is Solar Together Norfolk open in 2026?
Not on 30 October 2026. The scheme, now called Switch Together, runs in rounds; the latest one we found, in King's Lynn and West Norfolk, closed to registrations on 25 September 2026. Check your district council's page for the next round.
