Renaissance Pubs Limited

Renaissance Pubs Limited is an expanding chain of gastro pubs. We have used Carbon Accountancy since the early days and have always found them friendly and pro-active as well as professional. They have always provided their service on a fixed fee basis and we have never had any nasty surprises. They are happy to provide advice outside the scope of preparing accounts within their annual fee.

Nick Fox, CEO

Hudson & Co

Hudson & Co is a London based firm of solicitors and as such we have to have our client account money audited for the Law Society – Carbon Accountancy have always done the audit with minimum disruption to the firm and on a fixed fee basis. They also do the firm's accounts and tax returns. I would have no hesitation in recommending them as accountants to any company or professional individual. 

David Hudson, Solicitor

Magic Breakfast

As a growing charity we need advice on a regular basis, but as a charity we want to ensure that our financial resources go towards our charitable objectives. Carbon Accountancy provides us with a cost effective solution – they haven't charged us a penny in over five years!! On top of that they are easy to deal with and turn things around quickly.

Carmel McConnell, CEO

Intellistream Limited

As a venture capital backed company it is essential that we have information produced on time each month. Carbon Accountancy provides a full accounting service – everything from payroll and book-keeping to financial and commercial advice – all at a fixed monthly fee, making it easy to control cost and budget effectively. The team is friendly and pro-active and I would have no hesitation in recommending them.

Jim Beagle, CEO

YouGovStone Ltd

Carbon Accountancy have been my accountants since 2003 and I am very pleased indeed they were recommended to me. The service provided has been excellent - they take a real interest in my business. Their advice is sound and I regularly ring them for off the cuff advice. The fixed fee is very reasonable - I have on more than one occasion actually insisted they charge me more!!

Carole Stone, Managing Director

CT Investment Partners LLP

Carbon Trust Investments is a venture capitalist which invests in clean technology companies that develop energy efficiency and renewable energy technologies. We have used Carbon Accountancy for financial due diligence work and found them fast, reliable and commercial in their advice. We widened the scope of their work slightly but they still stuck to their fixed fee – a genuinely refreshing experience.
