His company, Green Planning Studio Ltd, act as agents for appellants in public appeals, some of which can be high profile. Matthew Green is often a professional planning witness in these cases. The appeals take place after applications for planning permission have been refused by Councils, or after an enforcement notice has been issued. Green Planning Studio’s clients include Councils; applicants for planning permission ranging from individual householders seeking extensions to larger scale housing developers; and third parties who usually are objecting to a proposed development. The company's website claims: "Particular skills and success for projects in the countryside, Green Belt, Areas of Outstanding Natural Beauty and the historic environment". Some of Green Planning Studio’s clients are from the travelling community and their applications and subsequent appeals can attract significant press attention even for small scale developments. Green remained involved in politics after leaving Parliament, being mentioned by the
Shropshire Star as a potential Liberal Democrat candidate in the
2021 North Shropshire by-election. In 2024, Green stood as the Liberal Democrat candidate in the new constituency of
South Shropshire (this seat expands the borders of the old Ludlow constituency) and came second. == Personal life ==
