Solar Panels for Homes in the UK

Start with the home you actually have

Look at available roof faces, shading and condition. A roof survey should distinguish suitable panel space from the building’s total footprint. Leaseholders, shared roofs and tenants need ownership and permission questions settled before committing to a design. Read the roof and survey checks.

Collect annual electricity consumption in kWh from the bill. Separate electricity from gas, and consider how planned vehicle charging or electric heating might alter demand. A bedroom count is not an energy measurement.

Choose the tool for your stage

Use the savings calculator to see bill reduction separately from export income. Move to detailed payback once you know the installed cost and expected generation. The shared inputs travel within the same browser session where storage is available.

Already have a proposal? Check the quote for scope, inconsistent panel arithmetic and unspoken savings assumptions. Keep the original quoted claim and the calculator estimate separate.

Set a budget with a complete scope

Read the panel-cost guide and identify access, electrical work, commissioning and exclusions. Ask for a cash price even when considering finance. The online tools do not assess lending or promise future tariff savings.

If storage interests you, ask for a solar-only alternative. Battery backup, extra energy capacity and financial return are separate reasons to choose a system. Battery costs and export payment explain what changes its value.

Existing solar needs a different decision

A homeowner adding storage should retain generation history, inverter details and the FIT/export agreement. The original solar purchase does not become a new battery cost. Follow the existing-owner battery journey for the information an installer will need.

For a new installation, first verify the contracting business, certification, aftercare and payment terms. Our site provides research and comparison tools; it does not install systems or certify a proposed design.

Follow the survey context for your home

Read the terraced-house access guide, semi-detached roof guide, detached-house layout guide or bungalow roof guide. These explain property-specific questions without turning bedroom counts into a generation forecast.
