Guildford Chartered Accountants / Chartered Tax Advisers

About Us

We are Guildford (Surrey) based Chartered Accountants and Chartered Tax advisers, in the town centre, just 100 yards from the High Street. The firm is founded on traditional values. In everything we try to do, we attempt to serve others by following these principles:

“Treat others how you would like to be treated”

“If anyone would be first, he should be last and the servant of all”

These ethics are not just words given "lip-service", but are used to hire the right staff, for continual staff appraisal and much more.

In practice this means:

  • You won’t be sold something you don’t need;

  • We try hard to make ourselves available as much as possible: if we cannot answer your queries straight away, they are typically done within a few hours;

  • If a simpler, more economical service would better serve your needs, we will tell you and reduce the price;

  • We won’t lie to you, even in small things: no one will say some one is out when they are in;

  • We won’t hide from you on the rare occasions we make mistakes, but “bend over backwards” to resolve any problem as soon as possible;

  • We will work very hard for you to get what you deserve without complaint and as quickly as possible;

  • We invest heavily in staff training, compared to other firms, to provide the best possible service.
