We would like to say an enormous thank you to the many clients who provided their anonymous feedback to the Legal 500 team this year and are happy to see the firm's ethos of providing clear unambiguous advice and being readily accessible to our clients shining through in their comments. Thank you!

"Trevor Gibson ensures you work together in a collaborative manner which enables all parties to understand the risks, strengths or weakness of any proposals. He is a very strong negotiator and gains the respect of boards and senior executives"

"Jemma O’Reilly has an exceptional ability when undertaking investigations to expose the real positions and always ensures the issues are addressed"

"The thing I most like about Heminsley is its willingness to roll its sleeves up and muck in. The lawyers don’t give ’50/50 you decide’ advice but will get off the fence and look at practical solutions to often difficult problems. Even though they’re small they’ll give much larger firms a run for their money – in part through their skills & their ability to see through fog"

"Heminsley Law has long been my ‘go-to’ for advice as their team is readily available and provides advice that is clear and unambiguous"

"Trevor Gibson is one of the finest employment lawyers I have ever worked with. Always accessible Trevor makes complex issues seem simple, and exceeds expectations every time. "

"Heminsley Law’s ability to align to the customers’ needs, customise the advice and a constant touchpoint makes them ‘part of the team’. It’s very convenient to engage with the partners at Heminsley Law. Their expertise in Employment and Privacy is par excellence and helps navigate a litigation or dispute in an effective and cost effective manner"

"Heminsley is a fantastic specialist employment firm, providing a brilliant service to its clients. Very client focused, commercial advice."

"Heminsley has consistently provided our People Team with quick, pragmatic employment advice and guidance. Jemma really understands the business and tailors the approach to recognise the size and nature of the company"

"Heminsley Law is a ‘very sleek set-up’ that is led by Trevor Gibson. It advises companies on a wide range of people risks from employment law to bribery and corruption. The ‘accessible’ team frequently handles high-risk issues from whistleblowing and complex discrimination cases to IR35 bonus claims and the enforcement of restrictive covenants. Jemma O’Reily has an excellent reputation too. Another highlight for the team was Simon Stephen joining the firm from Gowling WLG."

"The service is delivered by a partner who  continues as your point of contact, accessibility is excellent which ensures issues are dealt with in a very proactive manner. The team’s strength is its ability to focus on the problems faced and its capability in addressing senior management issues raised during disputes and robustly refute claims in a very proactive manner leaving little opportunity for counter arguments to be raised"

"I have found Heminsley to be a really innovative and personable firm. They give their clients a really top-notch service."

“Heminsley is a fantastic boutique Firm. The team is always available, very proactive, client focussed and knowledgeable”

“Hensley are a fabulous firm. They are small but punch well above their weight. In many ways their size is to their advantage - Trevor and Jemma are able to offer a fantastic, efficient and personal service to their clients in a way that target firms just can’t”
