ExcluServ provides our clients with a team of people with expertise ranging from qualified and part qualified accountants, systems specialists and software developers.

Heinrich Groenewald 

Commercial Director

With his focus on the capacity of the business to deliver, Heinrich has overseen the steady growth of ExcluServ over the last 10 years. His strong business acumen ensures the team remain focussed and our operations remain sustainable, well resourced and profitable.

Paul Winnan

Director Consulting

With a background as a systems accountant, and 30 plus years working with mid-tier accounting solutions, Paul brings his experience to the consultancy offering from ExcluServ. This expertise is applied in all areas of the business and spills over into software solutions and outsourcing.

Richard Britten-Kelly

Technical Director

An experienced accountant Richard has intervened for different clients to develop finance teams, and oversee audits. He is now establishing and building our operations in Johannesburg to build on outsourced services and will be providing the support base for our software solutions.


ExcluServ is a private limited company, offering consultancy, software and accounting support to small to medium companies and UK & international NfP organisations. While our service offering is wide it is broadly always to enable them to get more from their finance function.

ExcluServ was established in 2005 by three founding directors, qualified CIMA accountants who saw that the services they were offering to one company could benefit smaller companies that would not have that level of expertise within their staff team. The company soon expanded to include a fourth director to lead on software development and a wider team of accounts staff, data processing staff, system specialists and software developers. As the importance of software development has grown, this has now been separated from the core of ExcluServ, and a new company called Xama Technology has been formed that we retain strong links with. 

ExcluServ operates out of the UK, South Africa and Bulgaria. Our main UK office is in the heart of the City of London and our South African team are based in the Rosebank area of central Johannesburg.



It is intrinsic to ExcluServ that the relationship with our clients is open and honest. We strongly believe that both parties must find the relationship beneficial.

ExcluServ is a private profit making company, but we are proud of our strong links to the charity sector and we reflect that in our values, and pricing model.

Our Work

ExcluServ will only enter into a contract with a client where we believe that we have the capacity and skills to deliver that contract at a level that we will be proud of, and the client will be pleased with.

ExcluServ will seek to always be open about issues that's come up and look to our staff to do the same. Issues and problems will always arise and staff and consultants will not always have the answers to hand – it is good to be able to recognise that, to seek assistance and to find the best way to resolve a problem when it happens.

Our People

At ExcluServ we want all of our employees to enjoy working for us. We know this can only be achieved if they are treated with respect, and we are reasonable and supportive towards them in their work. We do not adopt a “blame culture” and believe it is counter-productive to do so.

ExcluServ will only employ people who we are confident, are right for the organisation and who share our ethos.

Directors and some staff of ExcluServ hold governance positions for charities, and work voluntarily for charities that they personally have chosen to support. ExcluServ support our staff in doing this and believe that doing so is ethically right.


ExcluServ believe in the use of technology as a method by which greater value can be driven for organisations, meaning that the stakeholders in that organisation can derive greater benefit. We seek to work with organisations where this approach is shared, and where the benefits of knowledge sharing are valued.


We help clients in the multiple sectors within the UK and internationally.
