In addition to this, their payroll bureau handle all aspects of our busy payroll which some weeks can be in excess of 100 people.

In a world where every accountant appears to promise the best service, we have been delighted with the value and service levels we have received over the past ten years from Martin and his team at Haines Watts. They do what they say they will do by our agreed deadline and do it to a high standard. They also add value and offer us things from time to time which means they are thinking on our behalf. I would recommend Martin and the team to any small business needing accountancy services.

Haines Watts have helped us considerably. They made everything so much easier for us when we had to report our accounts to the EU and UK Government - we would not have managed it without the expert help and advice from Haines Watts.

Before moving to Haines Watts, our affairs were dealt with by a much larger firm. The difference in service is vast. Haines Watts are not only able to provide all of the services of a much larger firm, their cost structure is such that the services are much better value. In addition to this, the whole service is more personable. I see Mark on a regular basis which has proved invaluable. As an owner manager himself he easily relates to both the everyday issues I face in the business, and my future plans.
