Estimated solar yield for East of England

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: 960 kWh/kWp/yr

Annual generation: 4 × 960 = 3,840 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%)
1,536 kWh
Exported to grid (60%)
2,304 kWh
Import saving (24p × 1,536 kWh)
£369
SEG export income (15p × 2,304 kWh)
£346
Total annual benefit
£714

With a battery

A home battery typically raises self-consumption to around 75%.

Self-consumed (75%)
2,880 kWh
Exported to grid (25%)
960 kWh
Import saving (24p × 2,880 kWh)
£691
SEG export income (15p × 960 kWh)
£144
Total annual benefit
£835

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 East of England

UK Power Networks (UKPN)

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 East of England

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. Suffolk and Norfolk councils have historically participated in area-based retrofit programmes — check with your district or borough council.

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 East of England

Most UK solar installations fall under permitted development and do not require a planning application.

Most properties in the East of England proceed under permitted development. Homes in the Norfolk and Suffolk Broads or in designated AONB areas should verify planning requirements with their local authority before installation.

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.
