    He has represented clients in a wide range of goods and services and debt claims, at trial and at interlocutory and case management hearings.

    His recent instructions include acting for employers and employees/directors in civil claims arising from restrictive covenants, non-compete clauses and non-poaching clauses, and he is keen to develop his practice in these areas.

    Owing to his education and discrimination practices he is particularly well placed to act in claims relating to education contracts, and has experience in multi-faceted claims in that arena brought on the basis of breach of contract, discrimination and negligence.

    He has also acted in claims for injunctions under the Protection from Harassment Act relating to the use and enjoyment of property.

    Alex has experience in advising on lease renewals, service charge liabilities and the enforcement of covenants, as well as acting for both landlords and tenants in possession and disrepair cases.

    He accepts instructions from both local authorities and claimants in housing matters under the Housing Act 1996, and has a strong understanding of this area from his experience as a paralegal working in a housing and public law team at a solicitors’ firm specialising in these areas of work.

    Alex accepts instructions in discrimination, breach of contract and negligence claims arising in the context of schools, colleges and universities in the First-tier Tribunal and the civil courts, as well as school admission and exclusion cases and judicial review cases relating to education.

    Alex’s previous experience of working in higher education policy means that he is particularly interested in cases in the higher education context, including discrimination and breach of contract claims, judicial reviews and cases involving complaints to the Office of the Independent Adjudicator for Higher Education.
