Professional Negligence Solicitors in Cardiff

Cardiff professional negligence solicitors providing clear advice on claims against solicitors, surveyors, accountants and other professionals.

Specialist expertise in professional negligence claims in Wales and England

Berry Smith’s professional negligence solicitors in Cardiff act exclusively for claimants across England and Wales. We can help you with any claim you may have against your professional advisors. Don’t just take our word for it – we are one of only a few law firms recommended in Wales by both the Legal 500 and Chambers and Partners independent guides to the legal profession as having a recognised expertise in claims for professional negligence.

Chambers and Partners has reported that they know what they are doing in claims for professional negligence, whilst the current 2026 edition says “They have serious expertise, which is difficult to find in the local legal market” and that “Berry Smith punches above its weight and has some really good people.”

Legal 500 top ranks the team in Wales, and the current 2026 edition says, ‘The professional negligence team at Berry Smith is particularly adept at handling cases relating to properties and property transactions.’

What types of professional negligence work do we conduct?

Berry Smith acts exclusively for claimants across the whole of England and Wales and provides what the Legal 500 described as “Small firm service and costs but with big firm expertise”. We have successfully helped individuals and businesses, ranging in size from multinational insurance companies to sole traders, to bring claims against all types of professionals.

Whilst we have a nationally recognised expertise in property-related professional negligence claims, we have also been able to help our clients in claims against Solicitors, Barristers, Accountants, Construction Professionals (including Architects and Engineers), Surveyors, Financial Advisors and Insurance Brokers.

The team has a range of specialists able to assist in claims against every type of professional, led by the head of the Dispute Resolution Department, Iwan Doull, along with the Head of the Property Litigation Team, Simon Care.

Professional Negligence Claims We Handle

We act for individuals and businesses of all sizes, from sole traders and private individuals through to multinational insurance companies, on claims against every type of professional. Whilst we have nationally recognised expertise in property-related professional negligence, our experience extends across the full range of professional services.

Claims Against Solicitors and Barristers

We act on behalf of clients who have suffered loss as a result of negligent legal advice or representation – covering every aspect of legal work, including conveyancing, litigation, family law, and commercial matters.

Claims Against Accountants

Where negligent tax advice, audit failures, or poor financial guidance have caused financial loss, we advise clients on the merits of their claim and the most effective route to recovery.

Claims Against Surveyors and Construction Professionals

We have significant experience in claims against surveyors, architects, engineers, and quantity surveyors – including complex multi-party disputes involving development projects and construction contracts. Our professional negligence guide sets out what you need to establish to bring a successful claim.

Claims Against Financial Advisers and Insurance Brokers

Where poor investment advice, negligent pension planning, or a failure to obtain adequate insurance cover has resulted in financial loss, we assess the strength of your claim and advise on the most effective approach to recovery.

Our Track Record in Professional Negligence

The most reliable indicator of our capability is the work we have successfully completed. Our team has acted on a significant number of high-value professional negligence claims, including:

  • A claim exceeding £3m against boutique London family law solicitors and a King’s Counsel for negligent settlement advice
  • Multiple claims against solicitors and barristers on behalf of a global legal expenses insurer
  • A claim exceeding £1m against a global firm of accountants for negligent tax advice
  • A claim of £0.7m against regional accountants for negligent advice on tax mitigation schemes
  • A claim of £1m against financial advisers for negligent advice on a settlement trust
  • A claim exceeding £0.9m against insurance brokers for failure to obtain adequate insurance cover
  • A multi-party claim exceeding £3m against architects, engineers, and quantity surveyors relating to a London property
  • Representation of a local authority in a claim exceeding £1.5m against specialist asbestos surveyors

Nationally Recognised Expertise in Professional Negligence

Our professional negligence team is led by Iwan Doull, head of our Dispute Resolution department, and Simon Care, head of our Property Litigation team. Both are individually recognised by the leading independent legal directories as outstanding practitioners in this field.

Chambers & Partners describes Iwan as a first-rate solicitor who genuinely fights for his clients, noting that his expertise in professional negligence is difficult to find elsewhere in the local legal market. Legal 500 recognises Simon specifically for his skill in property-related professional negligence matters, describing him as a gifted lawyer who fights for his clients.

Our team is regularly instructed on claims of significant value from complex, multi-party disputes to high-value claims against global professional firms. We bring the same level of commitment and expertise to every instruction, regardless of size.

What Our Clients Say

The best indication of what we deliver is the experience of clients who have worked with us. One client, Robert Howell, Plant Hire and Construction, described their experience of working with Iwan in a professional negligence claim against their own solicitor:

“Where other solicitors had taken things at face value, Iwan took the time to fully understand the case, thought outside the box, and came up with a plan of attack. He kept us fully informed at all times. He was not afraid to be honest and told us when things were not likely to go our way, instead of the usual ‘tell them what they want to hear’. We only wish Iwan were on our team from the beginning of this case.”
