The survey confirms the design.

Next steps

Calculator results are estimates based on the figures you enter and general assumptions. They are not a quote. Your written quote after a no-obligation survey shows the full price and the expected generation for your roof.

Design inputs

A good design considers each roof face, its pitch and orientation, nearby shading from chimneys, trees and buildings, the electrical supply and the network connection rules. In Scotland, systems up to around 3.68kW per phase usually connect under G98 notification, and larger systems need G99 approval from SP Energy Networks or SSEN.

From design to quote

The designer gives a starting point. Your survey confirms the layout, and your written quote shows the final design, equipment, expected generation and full price.

Solar on Scottish roofs

Scottish roofs vary more than most. Sandstone tenements in Glasgow and Edinburgh often have natural slate on steep pitches with valley gutters and rear slopes facing back greens. Granite houses in Aberdeen and the north-east frequently have dormers and chimneys that cast shade. Interwar and post-war council-built homes usually have concrete interlocking tiles that are straightforward to work on, while newer estates around Livingston, Dunfermline and Inverness tend to have simple gable roofs that suit a neat array.

Fixings are chosen for the roof covering and for the wind exposure of the site, which matters on the west coast, in the islands and on high ground. A survey also checks the roof timbers and slate condition before any panels go up, because it is far easier to fix a roof problem before an installation than afterwards.

How our survey works

Every project starts with a no-obligation survey. We look at your roof orientation, pitch, shading and condition, your fuse board and meter position, where a battery or inverter could go, and how your household uses electricity through the day and across the Scottish seasons. You then receive a written quote showing the equipment, the expected generation for your roof and the full price, so you can compare it fairly. We handle the network connection paperwork with your local distribution network operator, which is SP Energy Networks in central and southern Scotland and SSEN in the north, Highlands and islands. We install through MCS-certified partners. Solar panels and batteries are 0% VAT until March 2027. Finance available, subject to status.
