The Scottish Government recently announced that it would be easing permitted development rights (PDRs) for rooftop solar. But what do these changes mean and how will they allow consumers access to cheaper electricity? Also, how will these changes support the country’s ambitious climate change targets, including the toughest statutory emissions target in the world, which stipulate that Scotland aims to supply 50% of its total energy demand (electricity, heat, and transport), from renewable sources by 2030, and targets a 75% emissions reduction by 2030?

What are the changes?

Laid before the Scottish Parliament on Thursday 28 March 2024, the proposals are expected to come into effect on Friday 24 May 2024, subject to parliamentary scrutiny. The changes remove the upper limit of a maximum of 50kW total energy output from equipment installed on the majority of domestic and non-domestic buildings and means that most rooftop solar projects that are progressed outside of a World Heritage site or on listed buildings no longer need planning consent. This includes many projects within conservation areas.

What makes these changes welcome?

These changes have been campaigned for over several years. Simplifying the planning process for rooftop solar will make a substantial difference in Scotland’s ability to deliver 6GW of solar power by 2030. With energy costs remaining stubbornly high, solar power remains one of the most effective ways to reduce the expenses of running residential and commercial buildings. This change by the Scottish Government will make the process of installing solar quicker and easier.

How do they compare to the policy in the rest of the United Kingdom?

The changes bring Scotland largely in line with England where a similar change was made on the 30  November 2023. There are some differences between the two nations depending on the type of building. As such, the detailed planning guidelines in each nation should be followed to ensure that a rooftop solar project stays within the permitted development rights.

What is the impact to consumers?

Changes on both sides of the border are aimed at cutting red-tape in the planning system so that homeowners and businesses can install solar panels without being held up by costly delays. The permitted development announcement in Scotland extends beyond rooftop solar to introduce them for free-standing solar panels within the curtilage of non-domestic buildings (up to 12 sq m).

Furthermore, certain restrictions have been relaxed for solar canopies in carparks, including removing the requirement that these must be primarily for the purpose of powering electric vehicle chargers. This policy is an important step on Scotland’s journey towards net zero.
