Carbon Impact Calculator Scotland
Quick answer
The carbon calculator helps you think about how solar, batteries and heat pumps change where your home's energy comes from. It is an educational tool and its results are indicative only. We install through MCS-certified partners across Scotland. Savings depend on your roof, usage and tariff, and a no-obligation survey gives figures for your home.

The carbon calculator helps you think about how solar, batteries and heat pumps change where your home's energy comes from. It is an educational tool and its results are indicative only.
How it works
It uses the electricity you generate and use, and general assumptions about grid electricity and heating fuels. Grid carbon intensity changes over time and by hour, so results are approximate.

Scotland's grid
Scotland generates a large share of its electricity from renewables, especially wind. Replacing oil or gas heating with a heat pump typically has a bigger effect than solar alone.
Using the results
Treat results as a guide to the direction of change rather than a precise figure.
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.
