Verdict
Choose Dodl if…
Cost-conscious beginners who want AJ Bell's backing and FSCS protection without AJ Bell's full range or capped-fee complexity. The flat 0.15% with no dealing fees is simple and competitive at smaller portfolio sizes.
Choose Fidelity if…
Fund investors who want a broad range of active and passive funds with no dealing charge. Fidelity's 0.35% rate is cheaper than HL for funds, and it offers a junior ISA for families.
