Thanks for visiting my website!

A bit of background, I’ve been the onboard voice for the Great Western Railway (GWR) network in the UK since 2017.  I was chosen as my voice has a neutral tone with a slight Welsh lilt, and the network covers both England and parts of Wales.  It’s a great company to be part of and I’m very proud of my work for GWR.

I’m also one of the train announcers on the highly popular Stepford County Railway game for Roblox, the onboard announcer for the Stena Line ferry between Holyhead and Dublin, and since 2025 I have been one of the announcers for the fabulous company UK Departure Boards (alongside Elinor Hamilton, Matthew Streeton and the voice of Phil Sayer).  

I’ve also been interviewed on The Jeremy Vine Show on Radio 2 talking about my train announcements, and I was given a spoof Radio 2 train announcement to perform live on air.  I’ve also been on a couple of podcasts talking about my work, including “How Do You Say That” with Mark Ryes and Samantha Boffin.  For three years I announced “Magic in the Skies”, a spectacular summer firework display at Land’s End.

As well as keeping you entertained on your rail journeys, I’ve been a voiceover artist for 25+ years for radio stations and production companies in the UK, Europe and beyond. I voice for a wide number of organisations across the public and private sector, including in-store commercials (eg, New Look), training modules, corporates, explainers, onhold, IVR (eg, the GoDaddy helpline), e-learning, audiobooks and video games. I’ve been told I’m adaptable, dependable and easy to work with and I certainly enjoy the challenge of each and every project that comes my way.

My voice has been described as distinctive, clear, warm and engaging - with that added hint of a Welsh lilt. I’m also comfortable voicing in a more neutral/RP - I was born in Kent. I’m also a Welsh learner (I’m really good at pronouncing all those tricky Welsh place names!) and I’m happy to voice the odd sentence or two. I also know my limitations so if it’s a full on Welsh language script, I have one or two VO colleagues tucked up my sleeve who I’d be delighted to recommend.

I work mainly from my broadcast-quality studio in Cardiff, the fabulous capital of Wales, where I’m able to connect with other studios throughout the world via the wonders of modern technology. I don’t just record live sessions though, I’m also trusted by the majority of my clients to self-record and send through audio when the job is complete. And when I get the chance, I love travelling to studios throughout the UK too. It’s always good to meet clients and producers face to face from time to time - human connection, yay!
