Areas of expertise

Editorial focus

On the Connection Technologies blog, Callum publishes long-form guides aimed at decision-makers in finance, IT and operations roles inside UK small and mid-sized businesses. Coverage spans business mobile networks (EE, O2, Vodafone, Three and the major MVNOs), hosted VoIP and SIP trunking, business broadband and SoGEA, Microsoft 365 and managed IT support, the Cyber Essentials and Cyber Essentials Plus frameworks, and the UK B2B energy market — including fixed and pass-through tariffs, broker selection, and procurement timing.

Every guide is checked against current provider pricing, network coverage data and regulatory documentation before publication. Articles are updated when material changes happen — Ofcom rule revisions, mobile network mergers, the ongoing PSTN switch-off, or significant supplier price moves. The aim is straightforward: give buyers the same information their procurement team would surface after a week of supplier meetings, written for people who need to make a decision rather than read a sales pitch.

How to work with Connection Technologies

Callum is part of the team at Connection Technologies, an independent UK telecoms and IT brokerage. The business compares contracts across every major network and provider on the buyer's behalf, negotiates pricing, and project-manages installations so SMEs aren't left juggling four suppliers at once. If a guide on this site is relevant to a problem you're trying to solve, the quickest route to a tailored quote is to contact the team directly.
