Common Questions
Frequently asked questions.
What is data governance consultancy?
Data governance consultancy helps organisations define who owns their data, how it should be managed, and what standards govern its quality, access, and use. A specialist data governance consultancy such as Mayfair IT Consultancy works alongside public sector and financial services organisations to design governance frameworks, establish data ownership, implement data quality processes, and ensure compliance with UK GDPR and sector-specific regulations.
How does Mayfair IT Consultancy support UK central government?
MITC delivers three core services to UK central government: data transformation (modernising data estates and analytics capability), DDaT agile team allocation (deploying SC and DV cleared digital professionals rapidly), and network security (protecting critical infrastructure against cyber threats). We have worked with HMRC, DWP, ONS, the Home Office, the Ministry of Justice, and the UK Intellectual Property Office, among others.
What is DDaT agile team allocation?
DDaT (Digital, Data and Technology) agile team allocation is the rapid deployment of security-cleared technology professionals — individually or as complete multidisciplinary squads — to fill capability gaps in government delivery programmes. MITC maintains an active network of SC and DV cleared DDaT specialists and can present a shortlist within 48 to 72 hours of a requirement being agreed, with mobilisation typically within five to ten working days.
How do I find a reliable cyber security consultant in London?
The most important criteria when selecting a cyber security consultant for UK public sector work are: relevant clearances, demonstrable experience with NCSC frameworks and HMG Security Policy, and an understanding of the specific regulatory environment (PSN, CJSM, or financial services equivalents). Mayfair IT Consultancy is headquartered in Mayfair, London, holds Cyber Essentials Plus certification, and has delivered network security programmes for central government departments on sensitive infrastructure.
What makes Mayfair IT Consultancy one of the best data governance consulting services in the UK?
MITC combines deep technical delivery experience with a genuine understanding of the operational and political context of UK public sector programmes. We are a Crown Commercial Service (CCS) supplier, a Cyber Essentials Plus certified organisation, and an MSDUK-certified minority business. Our data governance work is embedded within wider data transformation programmes, meaning clients get frameworks that are practical, technically grounded, and built to last — not advisory reports that sit on a shelf.
Is Mayfair IT Consultancy a Crown Commercial Service (CCS) supplier?
Yes. MITC is a Crown Commercial Service supplier, enabling UK public sector clients to procure our services through CCS frameworks without a full open tender process. We are also aligned to G-Cloud 14 for cloud-based service delivery. Our clients include central government departments, arm's length bodies, and NHS organisations.
