Durham City receives approximately 1,140 peak sun hours per year, with south-facing properties on the hillside suburbs particularly well-positioned. A typical 4kW system in Durham City generates 3,150–3,550 kWh per year. Combined with current grid electricity prices and Smart Export Guarantee rates, that gives most homes a payback of 6–9 years on solar-only, dropping to 5–7 years when paired with a battery on a time-of-use tariff like Octopus Go or Intelligent Octopus.
Over the panels' 25-year warranty period, a Durham City homeowner can typically expect £18,000–£28,000 in combined bill savings and SEG income from a 4kW system, or more with a battery.

SEG export rate per kWh
Most Durham City homes fall within our standard pricing bands above. The main variables that can move the price are:
Roof complexity
Multi-pitch or hipped roofs in Durham City need more panel arrangement work and sometimes more mounting kit.
Access
Three-storey properties or hard-to-scaffold houses (back lanes, tight terraced streets) attract additional scaffolding cost.
Inverter & battery
A hybrid inverter is included; a separate battery inverter or a high-capacity battery (15kWh+) pushes the total higher.
Electrical upgrades
A small minority of older homes need a consumer unit upgrade for the install — surveyed in advance.
Conservation or listed status
Some streets in Durham City sit in conservation areas. Standard solar usually still qualifies under permitted development, but listed buildings may need consent and a different panel finish.
Local context
The Durham World Heritage Site buffer zone covers a substantial chunk of central Durham — including parts of the peninsula, the Bailey, Saddler Street and Silver Street — and any visible alteration to roofs within it can require both conservation-area consent and a heritage assessment. The good news for solar is that the suburbs ringing the city (Belmont, Bowburn, Framwellgate Moor) sit well outside the buffer zone with no additional restrictions.

Economic context
Durham’s economy is anchored by Durham University (one of the UK’s top universities), Durham County Council itself, and a growing knowledge-economy cluster at NETPark in Sedgefield. Buy-to-let student lets dominate parts of the city centre.
Energy context
Durham County Council declared a climate emergency in 2019 and is targeting a net-zero council estate by 2030, alongside a wider county net-zero ambition for 2045. Durham City’s World Heritage Site (cathedral + castle + their setting) creates specific planning constraints in the historic centre.

Worked example
Imagine a typical Durham City household: a 3-bed semi using around 3,800 kWh of electricity per year at a unit rate of around 28p/kWh. They install a 4kW solar system for £4,999 and add a 5kWh battery for another £4,000, total £8,999. Here's how the numbers play out:
| Item | Per year |
|---|---|
| Solar generation in Durham City (4kW) | 3,150–3,550 kWh |
| Direct self-consumption (no battery) | ~30-40% |
| Self-consumption with 5kWh battery | ~70-80% |
| Electricity bill saved (with battery, ~28p/kWh) | ~£700-900 |
| SEG export income (~15p/kWh average) | ~£100-150 |
| Total annual benefit | ~£800-£1,050 |
At those numbers, the £8,999 capital cost pays back in roughly 9-11 years. Over the panels' 25-year warranty, the system continues to generate income for a further 14-16 years after payback — typical 25-year lifetime benefit is £18,000-£28,000 in combined savings and export income, excluding any future electricity price rises (which materially improve the numbers further).
Sensitivity: every 2p/kWh increase in retail electricity prices adds roughly £75-£100 to the annual benefit. Every 5p/kWh increase in SEG export rates adds roughly £30-£60. Both have been rising historically.
Smart Export Guarantee
The Smart Export Guarantee is paid by your electricity supplier — not by the government — and rates vary materially. You're free to choose any SEG supplier regardless of who supplies your import electricity. Current notable options:
Octopus Outgoing Fixed
~15p/kWh fixed export rate. Among the best mainstream rates available. Requires a smart meter sending half-hourly readings.
Tesla Energy Plan
Up to 24p/kWh — currently the highest available SEG rate. Restricted to customers with a Tesla Powerwall battery installed.
Eon Next Export
~3-7p/kWh. Available to most customers. Lower than the leading offers but no requirement to switch import supplier.
British Gas Export & Earn
~6-15p/kWh depending on plan. Bundle options for customers also importing from British Gas.
Rates are reviewed periodically. We help you check current offers and register with your chosen supplier as part of the Durham City install — you don't need to research this independently.
Paying for it
Most Durham City customers pay cash from savings — solar is one of the highest-return uses of cash savings currently available in the UK. For customers who prefer to spread the cost:
Local cost factors
Two Durham City houses on the same street can end up with different solar quotes. The variables that move price most:
Larger systems cost less per kW than smaller ones, because survey, scaffolding, DNO notification and MCS paperwork are fixed costs spread across more panels. A 6kW install isn't 1.5× a 4kW install — it's typically closer to 1.3×. For Durham City properties with the roof space, fitting all you can is usually the better economic decision.
Most Durham City properties are two-storey, which fits within our standard scaffolding allowance. Three-storey properties — common in central Durham City terraces — and properties with restricted access (back lanes, courtyards) attract additional scaffold cost, typically £200-500.
Battery price scales with kWh capacity. A 5kWh battery typically adds £3,500-£5,000 to the install, 10kWh adds £4,500-£6,500, and 15kWh+ adds £6,000-£8,500. Most Durham City homes get the best payback from a 10kWh unit sized to cover evening and overnight consumption.
Properties in Durham City conservation areas (Durham City Centre, Crossgate and others) may need all-black panels and sympathetic mounting. The hardware costs slightly more, but the difference is rarely more than £200-400 over a standard install.
Durham City has a varied mix of housing ages. Pre-1980s properties sometimes need a consumer-unit upgrade as part of the install — we check during the free survey and quote it transparently if needed.
