Booth Ainsworth

Booth Ainsworth is a full service Chartered Accountancy practice that specialises in the legal sector. The legal discipline is headed up by Partner, Gary Cook, who embarked upon developing this niche sector long before other accountancy firms considered specialising.

Gary is the award winning lead partner who manages his highly specialised team at their office based in the North West. He has developed significant experience over the last 20 years in advising hundreds of legal practices. The services range from offering pro-active tax advice, efficient and effective structures, consultancy and compliance. Over that time the team has gained client confidence and trust by conducting their work with skill and understanding of what is required for the legal sector.

With the team’s commercial expertise and technical knowledge they are able to meet the needs of all types of legal practices, no matter what their service-line, size or location. Clients in the North West range from city centre based firms (10+ partners) to 1-5 partner practices, with each having different challenges and objectives.

Gary’s innovative approach to advising legal clients demonstrates an individual style that has shortlisted him for a number of industry awards. He held the 2020 Innovation Marketing Person of the Year award, which reflected his pro-activity within the legal sector. He has clients who have won many prestigious awards, including an OBE, and the Manchester Law Society Small Business of the Year award. Each firm has benefited from the service offered by the team, which includes benchmarking surveys, seminars, marketing support, industry emails and so much more besides. Using the Professional Practices’ team can make a real difference to your business.

Award winning client, Roberts Jackson, has spoken highly about the level of service they have received from Gary and the Professional Practices team at Booth Ainsworth, which has been instrumental with the initial set up of their business and provided guidance during the subsequent period of accelerated growth which placed Roberts Jackson at the forefront of their competitors and enabled Manchester Law Society to recognise them as winners of the Small Business of the Year.

“We have been dealing with Booth Ainsworth from our inception. It was the best decision we have made and Gary is one of our most valuable partners.

The technical accountancy advice we have received has been exceptional but the additional value of the relationship has been the outstanding sector specific experience that Gary has in law. The consultancy advice he provides at our regular quarterly meetings has been vital to our initial structure and to our on-going success. Gary has many law firms going through or has already gone through and dealt with the raft of changes we are faced with. It is therefore the in-depth sector knowledge, experience and benchmarking ability that sets Booth Ainsworth apart from its rivals.”
