Niche - or boutique - firms
Niche - or boutique - firms have a specific area of expertise in a specific industry or sector.
Across the sector there are outstanding ’boutique firms’ (typically fewer than 250 employees) gaining recognition for expertise and excellence in many different areas.
The Financial Times’ annual survey of the UK's Leading Management Consultants recognises smaller, boutique firms wining ‘gold medals’ in their fields for the quality and value of the services delivered to clients. Examples of boutique consulting firms hiring graduates include CMG Consulting (focused on change management and technology-led change) and White Space Strategy (an Oxford based consulting firm focused on growth strategies).
The Management Consultancies Association (MCA) also recognise the quality among boutique firms. 50% of finalists shortlisted for the 2025 Management Consultancies Association Annual Awards were SMEs. Since 2024, the MCA has annually Awarded the ‘Best New Consultancy’ award, celebrating consulting firms which have been operating for fewer than 7 years.

Boutique firms also advertise throughout the year on CareerConnect and attend the Finance and Management Consultancy Fair.
Careers offers exclusive consulting opportunities with boutique firms through the Micro-internship and Summer Internship Programmes.
Example Specialisms
Brand: firms work with organisations to strategically define, articulate, and strengthen their brand ensuring it succeeds in competitive markets. The role sits at the intersection of strategy, business problem solving and creativity. It includes responsibilities such as conducting research, analysing customer and market insights, and developing strategic recommendations that shape brand positioning, messaging, and identity. This involves working closely with senior stakeholders, designers, and marketing teams to build impactful brands. It is ideal for analytically and strategically minded individuals who are also creative and excel at storytelling. Work is fast-paced, project-based and varied. Example organisations include Lippincott, Brandpie, FutureBrand, Accenture Song, Landor and Brand Opus.
Economic: firms generally hire students studying economics and are particularly interested in masters and DPhil candidates who combine a strong foundation in economic theory with good research and analytical skills. For some positions, knowledge of Stata, R, Python or Excel can be helpful. Projects may include analysing market share, pricing and potential consumer harm relating to large corporate mergers, modelling the economic effects of new infrastructure and using economic models to guide clients expanding into emerging markets. There are Oxford based firms such as Oxera (also in London and Europe). Specialist firms include Cornerstone Research, Frontier Economics, NERA, RBB Economics. Larger firms with a strong economic consulting practice include FTI Consulting and Charles River Associates.
Education: firms may work with education providers to design and develop curriculum and new strategies. Alternatively, freelance consultants may deliver training to organisations to help cultivate talent. International based consultancies may work with families and pupils to advise students through admissions processes. Strategy consultancies may provide strategic advice to education institutions, sometimes partnering with foundations or international charities. Projects could include transformation programmes, funding strategies, and overcoming educational disruptions. You can read examples of education-related consultancy projects on McKinsey’s education and BCG’s education pages. Examples of specialist firms include SUMS Consulting, which delivers projects around strategy and transformation, and Optimus Education, which supports clients with reviews of safeguarding, curriculum, pupil premium, school culture, leadership and SEND.
Energy: this is a growing area and a number of firms do not require specific degree disciplines or experience for their graduate programmes. Read the Energy sector page and consider your interests in the global energy transition and renewables sector. Learn more about example energy consulting graduate schemes such as those offered by Aurora Energy Research and EON. The latter has its own in-house consulting team, ECON, of around 115 consultants, involved in key projects and strategy challenges.
Health and life sciences: healthcare consultancies may provide expertise to healthcare organisations to improve services and efficiencies whilst reducing cost. This could involve digital transformation across a range of areas including programme and project management, data, analytics, communication and engagement. Life science clients are typically pharmaceutical, biotechnology, medical device, diagnostic and healthcare technology companies. Projects may include the development and launch of medicines and technology whilst navigating complex regulations. Roles exist across global and specialist firms, and NHS consultancy teams. Example firms include ClearView Healthcare Partners, Carnall Farrar, IQVIA and Trinity.
Technology: firms specialise in areas such as AI, cybersecurity, digital transformation and data science and consultants will often possess deep technical expertise. Clients have growing concerns around cyber security, particularly after high profile attacks on organisations like Co-op and Jaguar Land Rover. Market growth of the cyber security consulting market is predicted to double in 2025/26. The fast-paced change in AI has also led to a surge in demand. Example firms include Kubrick Group, Infinity Works (part of Accenture), Netcompany and Equal Experts.
Larger vs smaller firms
A large firm might offer a broader range of opportunities in terms of projects, team size, and location however this is not always the case, and in some instances, new recruits may be constrained to one area for some time. Smaller firms will perhaps have more localised opportunities and a more specific field of expertise. New recruits are usually involved in a broader range of tasks in each project and may get to work closely with senior consultants from the start. It is common to move between smaller and larger firms and vice versa, and for consultants to later join a client they have worked with.
