Martin grew up in Liverpool and progressed successfully through the youth ranks at Brighton and was awarded a professional contract in September 2004 on reaching his 17th birthday. During that time, the highly rated 'keeper was a target for a number of premiership clubs including Liverpool with whom he trialled in 2004 and Everton in 2006. Martin made his first team debut for Brighton in a pre-season friendly against Le Havre AC and went on to feature in four more ties including starts against Oxford United and AFC Bournemouth. During the course of the 2005–06 season, he made fourteen appearances on the substitute bench as understudy to Irish international Wayne Henderson and also had a successful loan spell at Kingstonian, helping them move from 18th to seventh position in the league before being recalled by the club. At the beginning of the 2006–07 season, Martin was sent on a season-long loan to Conference South side Dorchester Town, making eleven appearances and helping Dorchester challenge for a playoff place before being recalled by Brighton after suffering an injury. Martin then went out on loan to Folkestone Invicta at the end of February 2007 and helped the club avoid relegation, playing in every one of their remaining games. Martin was released at the end of his contract in May 2007, his departure coinciding with that of long time goalkeeping coach John Keeley. In August 2007, two weeks before the start of the new Premiership season Martin, still without a club, was invited to train with Manchester City for a week by goalkeeping coach Eric Steele. However, injuries to Joe Hart and Andreas Isaksson resulted in Martin unexpectedly playing for City that weekend. After impressing in the friendly fixture, Martin was given a month-long contract. Martin continued to impress in subsequent Premier Reserve team fixtures, including a victory over Manchester United. This didn't go unnoticed as City bossSven-Göran Eriksson saw fit to extend Martin's contract to the end of the season.

However, a knee injury in September kept him on the sidelines until March 2009. On 17 April 2009, Martin joined Conference National league-leaders Burton Albion on an emergency loan as cover for their two remaining games of the season, after Kevin Poole suffered an injury. After a series of unfortunate injuries during the 2008–09 season, Martin's tenure at Manchester City came to an end. On 1 July 2009, Martin went on trial with League One side Yeovil Town and went on to appear in four pre-season games before signing a one-year contract prior to the start of the 2009–10 season.

His league debut came just under two weeks later on 12 September in Yeovil's 2–2 draw against Stockport County, being called into action after 22 minutes to replace Alex McCarthy who had been sent off. After making three league and two cup appearances during the first half of the 2009–10 season, on 19 January 2010, Martin was loaned out to bottom placed Conference National club Grays Athletic. Martin returned to Yeovil in February were the continued fine form of England U-21 goalkeeper McCarthy limited further first team appearances.
