About
Thirty years in IT, most of it accountable for the outcome.
I'm Jonathan McHarg. I started in technical services, moved through leadership, and now run an IT consultancy from Poole, working with businesses across Dorset, Hampshire and further afield.
Seven years consulting for Exxon Mobil, focused on disaster recovery and designing security solutions alongside Microsoft. Large-scale, high-stakes, and unforgiving of anything built on optimism.
A key driver in TMB Group's growth into one of the largest hospitality IT companies in the UK — building the partnerships, the service delivery and the technology that made it work.
Industry recognition along the way: Go:Tech "Top IT Support Team" and SolarWinds "MSP of the Year".
ISO 27001, Cyber Essentials, Cyber Essentials Plus and PCI DSS delivered across multiple sectors, with particular depth in hospitality.
Why that matters to you
I've spent years on the supplier side of the table. That's the main reason I'm useful when you're buying IT — I know how proposals are constructed, where the margin hides, and which "limitations" are technical rather than commercial.
It's also why I don't oversell. I've seen what happens to businesses that bought more than they needed from someone paid to sell it.
How I work
Three ideas run through everything:
Tell people what's actually wrong
Not a longer list — a truer one.
No surprises
Monthly statements on retained work, fixed prices on projects, and security reports that separate real problems from noise.
Be straight about limits
I'm one person. I'll tell you when something is outside what I can do, and where to go instead.

I also do business coaching
It grew out of the consultancy, because clients kept asking me about their business rather than their technology. Same person, different conversation.
Tell me what's going wrong.
No charge for the first conversation, and no obligation afterwards.
