If you've decided you need external strategic support, the next question is what kind. Two of the most common options are a fractional advisor and a consulting agency — and they're more different than they might initially appear.
What is a fractional advisor?
A fractional advisor — sometimes called a fractional director, part-time advisor, or strategic advisor — is an experienced individual who works with your business on a part-time or retained basis. They're not an employee. They're not delivering a project. They're embedded in your thinking and decision-making on an ongoing basis.
The value is continuity and trust. A fractional advisor knows your business, understands your history, and is available when you need them. The relationship compounds over time. The advisor who has worked with you for six months understands the context of a new challenge in a way that someone parachuted in for a project cannot.
What is a consulting agency?
A consulting agency or consultancy firm is a team of people engaged to deliver a defined piece of work. They come in, do the project, and leave. The output might be a strategy, a market analysis, a transformation programme, or an operational redesign.
The value is resource and specialism. If you need twenty people to implement a new system, or a team with deep technical expertise in a niche area, an agency can mobilise that in a way that a solo advisor cannot.
Agencies sell projects. Advisors sell relationships. The right choice depends on whether your problem has a clear end — or whether what you really need is someone in your corner consistently.
The key differences
Continuity
A fractional advisor builds context over time. The longer the relationship, the more useful they become. An agency's team may change between projects, and institutional knowledge is often lost in the transition.
Accountability
A fractional advisor is personally accountable. There's no team to hide behind. Agencies can sometimes diffuse accountability across a team — more people involved, but less clear who owns the outcome.
Flexibility
A fractional advisor can respond to what the business actually needs week to week. An agency relationship is typically governed by a scope of work — if the situation changes, the scope needs renegotiating.
Cost
Fractional advisory is typically more cost-efficient for ongoing strategic support. You pay for access to a senior mind without the overhead of an agency team. Agencies tend to be more cost-effective when you need to mobilise significant resource or specialist delivery capability quickly.
Which model suits which situation?
Choose a fractional advisor when: you need ongoing strategic challenge and a trusted sounding board; you're at a growth inflection point and need embedded support over months; you want accountability and continuity from one person who knows your business.
Choose a consulting agency when: you have a defined project with a clear output and timeline; you need specialist technical expertise or significant resource; you're running a transformation programme that requires a team to deliver.

Frequently asked questions
What is a fractional advisor?
A fractional advisor — sometimes called a fractional director or part-time strategic advisor — is an experienced individual who works with your business on a retained, ongoing basis. Unlike an agency, they are embedded in your thinking and decision-making over time, building context and trust that compounds in value.
What is the difference between a fractional advisor and a consulting agency?
A fractional advisor works as a single, ongoing strategic partner embedded in your business. A consulting agency provides a team engaged to deliver a specific project or piece of work. Agencies sell projects with defined outputs. Advisors sell ongoing relationships with compounding value.
When should I choose a fractional advisor over a consulting agency?
Choose a fractional advisor when you need ongoing strategic challenge, a trusted sounding board, or embedded support over months rather than weeks. Choose a consulting agency when you have a defined project with a clear output and timeline, or when you need specialist resource or significant delivery capacity.
How much does a fractional business advisor cost in the UK?
Fractional advisory retainers for senior strategic advisors in the UK typically cost between £1,600 and £4,800 per month, depending on the number of days per month and the advisor's experience level. This compares favourably to agency project costs while providing continuity and relationship depth.
