About 451 Analytics

451 Analytics is a bespoke Model Portfolio Service built for financial advisers who want technical rigour without sacrificing personalisation.

We work with UK and international advisers facing a decision every growing practice eventually confronts: build model portfolios in-house, or outsource construction to focus on financial planning and client relationships. Most Model Portfolio Services force a trade-off — either a generic, off-the-shelf range, or the time and governance burden of running an investment committee. We built 451 Analytics to remove that trade-off.

Founded by Glyn Chetwynd, who brings 26 years in financial planning, including 16 years as an external analyst conducting due diligence on other firms' investment processes, 451 Analytics is built on a simple premise: portfolios should be constructed with the same rigour an adviser would expect from their own due diligence, and priced transparently enough to withstand it.

We are the second-lowest-cost Model Portfolio Service in the UK, out of 1,681 providers charging manager fees, without compromising on methodology.

That methodology goes beyond headline performance figures. We report using performance metrics (risk adjusted, relative and absolute) and factor models because a single flattering number rarely tells the full story.

We are a boutique firm by design, not an MPS "burger chain." Our models are built around an adviser's actual client bank, not a fixed, off-the-shelf risk-rated range, and every adviser we work with has direct access to the analyst behind the numbers.

If your practice has outgrown ad hoc portfolio decisions, or you're weighing the true cost — in time, consistency, and evidencing under Consumer Duty — of building in-house, we'd welcome the conversation.
