We take you into account
Your business, your goals, our legal support

Flexible and transparent support
From ad hoc advice to outsourced DPO services, we provide the right level of support with clear pricing and no surprises.
Legal advice built built around your business
By understanding your operations and goals, we deliver legal solutions that reduce risk, support compliance, and build trust with your stakeholders and customers.
Your trusted partner in navigating data protection complexities
How our data protection solicitors can help
We help data controllers and data processors stay ahead of evolving data laws with tailored, practical advice. From start-ups to multinationals across fintech, SaaS, healthcare, retail and education, we make compliance clear and workable – whether you need quick answers, strategic input or breach support.
Data Protection Regulations
We guide you through UK General Data Protection Regulation (UK GDPR), the Data Protection Act (DPA) 2018, the Privacy and Electronic Communications (EC Directive) Regulations (PECR) 2003, and upcoming changes like the Data Use and Access Act (DUAA) 2025, ensuring your data handling, security measures, and business practices meet legal requirements.
ICO registration, enforcement response and data governance
We support ICO registration, enforcement response, and strong internal data governance. If you don’t have in-house resource, we can provide you with in-house DPO support – or we can act as your registered DPO through our outsourced DPO service, taking responsibility for your compliance as your business grows.
Privacy policies, cookie notices & internal procedures
We review or draft privacy and cookie notices, and design internal policies to meet compliance requirements and reduce risk. We also help assess and document your lawful bases for processing, including completing Legitimate Interest Assessments (LIAs) where appropriate.
Risk management & readiness
We identify and address vulnerabilities with Data Protection Impact Assessments (DPIAs), Data Protection Health Check audits, and cyber security guidance – keeping you one step ahead.
Subject Access Requests & Data Subject Rights
We manage Data Subject Access Requests (DSARs) and other rights request, ensuring accurate, timely responses and efficient handling processes.
Data breach management & incident response
We help you prepare for and respond to data breaches by developing robust a data breach and incident management plan, and supporting you with ICO notifications, investigations, and recovery.
Supplier due diligence & data-sharing agreements
We can carry out supplier due diligence and draft or review data-sharing agreements to ensure responsibilities are clear and risk is managed.
Digital platforms, marketing, & international data flows
We advise on compliant use of digital platforms, cross-border data flows, and consent management.

We support compliant employee data handling, from recruitment to exit, and deliver GDPR training programmes tailored to your team’s needs.

TESTIMONIALS
What our clients say
We help you stay focused by taking care of the legal detail – offering tailored support so you can focus on running your business.
Harper James solicitors don’t speak in the legalese which I have heard too many times from other solicitors and which is totally unhelpful. What I’m after is focused, considered advice about the specific situations that I face. By which I mean, do you think this is a good idea? Their response might be ‘Yes’ or ‘No’. One word is often all I’m looking for! My solicitor gives a view and I really value that.

Harper James has been invaluable. They drafted the relevant agreements and gave us sound legal advice in an area that we did not have prior experience in. As a start-up, having advice and feedback from an organisation that specialises in early-stage enterprises was instrumental in us having the confidence to push forward with our product

Harper James Solicitors provides excellent value for money and helps to cover gaps in specialist areas of legal practice. Using an outside legal provider enables us, as a business, to better manage our internal resources, the volume of work we have and to deal with our level of overall risk. I would undoubtedly recommend them to others.

Commercial Partner, Rob Cobley, helped us do the necessary due diligence and guided us on which online age verification solution offered us the best legal protection. We needed to eliminate any reputational risk and wanted a ‘gold-standard’ solution that set us apart from any competitors. Getting it right with all the 'belts and braces' gave us comfort because there are several different providers who achieve age verification in different ways. Navigating and implementing the solution was made possible with Rob’s help.
