I can't say I know of this company.
One of the best ways of getting a good accountant is by word of mouth. The first advantage is that the accountant will probably be local; a good idea for ease of taking stuff round and/or asking questions.
Talk to local traders and discuss how they've got on with their accountant. They'll soon let you know who are the good ones - or the rubbish ones.
Don't be tempted by whizzy adverts in the local press. The good ones probably wouldn't need to advertise!
But, to reiterate, a local guy who comes well recommended by local users is usually a very good bet.
