“Harding Lewis Limited and Andrew Gerrard have been my Company’s accountants for over twenty years. When I first set out with my business I was advised by a friend that the best money I would spend would be by employing a good accountant. That advice has served me well. It has been a privilege dealing with Harding Lewis all of these years – Andrew is the ultimate professional and this can be said for all of his fellow Directors and employees of whom I have also dealt with on many occasions and received a truly superb friendly, service. This backing has enabled me to concentrate on developing my business with the comfort that my accounts are all kept perfectly in order. Thank you so much Harding Lewis Limited."

Whilst we looked for that personal touch missing from larger accountancy practices we still required the back-up and expertise associated with such firms. In Harding Lewis, we believe we have found that combination. It is reassuring to deal with the same personnel in a friendly and progressive office." John G Harrison, Eurocycles
