The service provided by John and the team at Square One Law has been second to none. They are very approachable and provided commercial opinions which were always focussed around the best interests of Hirestreet.

The Square One Law team are excellent. They always provide us not only with rapid, detailed and most of all, cost effective guidance but also advice that is very commercial.

We’ve worked with Square One Law across our business from the start. They understand our proposition and can deliver in terms of us achieving quick turnaround times for our customer base, which will promote new benchmarks for the industry.

It is important to have a strong and trusted team of professional advisors. That is why I use Square One Law.

Peter StephensonExecutive Chairman, Able UK

The reason that our partnership has worked is that when you’re building a business you need to work with organisations that will take the time to understand your business, that have all the resource base that you need and that you trust. I think that when you build up a start-up you need to pull on a lot of resources and having an organisation that you can just lift up the phone – you can talk to somebody – and they’ll give you some interim advice on the spot, then that’s great; then you can go through more detail in the process.

The Square One Law team played a pivotal role in the launch and growth of North East Times. Their input extended beyond legal matters, offering crucial business advice that spurred our early initiatives. Recently, their support proved invaluable once more. Their guidance was key in securing a new investment, enabling our expansion into digital publishing and bespoke high-level events. Their pragmatic and efficient approach was refreshing and has made a big contribution to the growth of our business.

I would not have taken the business anywhere other than with Square One from my previous experiences but you all - without compromise - delivered over and above my expectations. My whole Team commented on a regular basis as to the professional and supportive interaction throughout the project. I cannot thank you all enough and would without question recommend Square One to anyone as my first choice for any legal advice. Great to work alongside and do business with good, kind, committed and professional people with great values.
