Why work with Charterhouse

Charterhouse is not a typical firm of accountants, we know that everyone says that but you only have to come into our office to realise it is true. From the images on our walls to the laughter and casual attire, this is nothing like what you would expect to see in a traditional accountant’s office.

Our whole approach is based on building relationships by taking time to get to know the people we work with; our clients, our partners and most of all our staff. Every client, no matter what the size, is assigned to a director or associate who oversees all the work done to ensure our service is of the highest quality.

We are tax planning specialists with expert knowledge in tax mitigation, with over 25% of our staff being tax professionals.

We are experts in property business planning, working with our clients to help them set up tax efficient structures to manage their properties and ensuring they get the maximum return from their property business.

We are not afraid of a challenge and we have a track record to prove it. Charterhouse are renowned for our persistence with HMRC, striving for that positive result for our client and it is this relentless drive to deliver good results for our clients along with our attention to detail that is our unique selling point ‘USP’.

From the beginning of our relationship, we work to understand your unique requirements and put the right team and support in place to meet these and at the same time maximising the value of your business and personal assets. From the start of your journey when you set up your business to the final day when you sell or close the business, whether it is through our tax planning, compliance, or business advisory services, we are your trusted partners.

I’ve been using the company for nearly forty years and whether its straightforward accountancy work or complex tax planning advice I can only praise and highly recommend.
