→ The Wales Act 2017 strengthened Welsh devolution by guaranteeing the Senedd’s permanence, requiring a referendum for abolition.→ It moved Wales to a reserved powers model, clearly defining what the Senedd can legislate on.
→ The Wales Act 2017 gave the Senedd power to set its own taxes, such as Land Transaction Tax (LTT), which replaced Stamp Duty in Wales.→ For example, as of April 2025, the main residential LTT rate is 0% for properties up to £225,000, and 6% for the portion from £225,001 to £400,00→ The Act granted significant new powers, including tax-setting, energy, and local governance.→ These changes increased Welsh accountability, self-determination, and brought Wales in line with Scotland’s devolution settlement.
