Estimated solar yield for Yorkshire and Humber
Based on a typical 4kW south-facing system at 35° pitch. Figures use conservative regional irradiance data from MCS.
How we calculate this
System size: 4 kWp
Regional irradiance: 845 kWh/kWp/yr
Annual generation: 4 × 845 = 3,380 kWh
Import rate used: 24p/kWh (standard flat tariff, Q2 2026)
SEG export rate used: 15p/kWh (best fixed rate, April 2026)
Without a battery
Typical self-consumption of 40% for a household home during the day.
- Self-consumed (40%)
- 1,352 kWh
- Exported to grid (60%)
- 2,028 kWh
- Import saving (24p × 1,352 kWh)
- £324
- SEG export income (15p × 2,028 kWh)
- £304
- Total annual benefit
- £629
With a battery
A home battery typically raises self-consumption to around 75%.
- Self-consumed (75%)
- 2,535 kWh
- Exported to grid (25%)
- 845 kWh
- Import saving (24p × 2,535 kWh)
- £608
- SEG export income (15p × 845 kWh)
- £127
- Total annual benefit
- £735
These are estimates based on regional averages. Actual yield depends on your roof orientation, pitch, shading, and specific panel technology. Rates used: 24p/kWh import (Ofgem Q2 2026 price cap standard tariff), 15p/kWh SEG export (best available fixed rate, April 2026).
Your Distribution Network Operator
Your DNO manages the local electricity network and must be notified before your solar system goes live.
DNO for Yorkshire and Humber
Northern Powergrid
G98 and G99 notifications
Systems up to 3.68 kW (single phase) can use the simpler G98 process — your installer notifies the DNO within 28 days of commissioning.
Systems larger than 3.68 kW, or on a three-phase supply, require G99 approval before installation begins. This can add several weeks to your timeline.
A good installer will handle DNO notifications as part of the installation process. Ask them to confirm this before you sign a contract.
Local grants and schemes in Yorkshire and Humber
There may be funding available to reduce the upfront cost of solar panels depending on your household income and energy rating.
England households may be eligible for the Warm Homes: Local Grant administered through local authorities. West Yorkshire Combined Authority and South Yorkshire Mayoral Combined Authority have both supported area-based retrofit schemes.
Also worth exploring
- ECO4— the government's main energy efficiency scheme for low-income and fuel-poor households, funded through energy supplier obligations. Eligibility is based on income and EPC rating.
- 0% VAT on solar — solar panels, batteries, and installation are zero-rated for VAT until at least 2027, saving around 20% compared to other home improvements.
- Smart Export Guarantee (SEG) — all licensed energy suppliers with 150,000+ customers must offer an export tariff. You earn money for every unit you send to the grid.
Planning permission in Yorkshire and Humber
Most UK solar installations fall under permitted development and do not require a planning application.
Properties within the Yorkshire Dales or North York Moors national parks require full planning permission. Urban properties in Leeds, Sheffield, Hull, and Bradford typically qualify for permitted development.
Permitted development
Applies to most houses. Panels must not protrude more than 200mm from the roof surface and must not be higher than the highest point of the roof.
Conservation areas
Permitted development rights may be restricted. Panels visible from the road or public right of way may require prior approval from the local authority.
Listed buildings
Full listed building consent is almost always required before solar panels can be installed on a listed property. Seek advice from your local authority conservation officer.
Planning rules in the UK are set at national level but interpreted locally. Always confirm with your local planning authority if you are unsure.
