Preston North End

Langmead began his career as a trainee at Preston North End joining in 2001. He spent a month on loan to Tamworth in the Football Conference, where he played two matches in September 2003.

Later in the same season Preston loaned him to then Division 3 club Carlisle. He played 11 matches, with his league début coming in a 4–1 defeat at Torquay on 6 March 2004. His first goal was at Mansfield in a 3–2 win on 24 April.

In September 2004 Langmead was again sent out on loan, this time to Kidderminster Harriers in the newly named League Two. He played 11 matches for the Harriers and scored one goal.

He then returned to Preston to make his only appearance for the club, coming on as a substitute in the Championship game against Millwall (1–1, 13 November 2004).

Shrewsbury Town

Two weeks after his Preston debut, he was again sent on loan, this time to Shrewsbury Town, this came shortly after the appointment of former Preston manager and youth development chief Gary Peters. Langmead played just three matches for the Shropshire club (scoring one goal) before making the move a permanent one, signing for £5,000.

Langmead then made more than 80 appearances in League Two for Shrewsbury as a striker. However, in September 2006, with a shortage of defenders, Gary Peters trialled him at centre-back in a reserve fixture. He was then utilised in this position for the first team, and was recognised in the League Two team of the week for his performance against Macclesfield Town on 6 October 2006.^[1] Langmead's success in this position saw him play out the rest of the season at centre-back, as Shrewsbury reached the League Two play-off final. Langmead also earned the Player of the Season award as voted for by both players and fans, for his consistency that term.

The following season, Salop's first at the New Meadow, Langmead was a little inconsistent this season, with a frequent change in defensive partners, Langmead was unable to find the form of the previous year.^[2]

At the start of the 2008–09 season, Langmead struggled to gain a place in the first team, as Paul Simpson preferred a central defensive partnership of Mike Jackson and Graham Coughlan. However, in the latter half of the campaign he regained a regular place, playing alongside Coughlan at the heart of the defence. The season ended in heartache for Langmead as Shrewsbury lost in the League Two play-off final for the second time in three years. In June 2009 he signed a new two-year contract.^[3]

Peterborough United

On 24 June 2010, he was sold to Peterborough United on a three-year deal for an undisclosed fee.^[4] On 7 August 2010, he made his debut in a convincing 3–0 home win over Bristol Rovers.^[5] He was virtually ever present for Peterborough United under Gary Johnson, however he fell out of favour under new manager Darren Ferguson. Langmead played over 40 times, scoring 4 goals, as the club gained promotion back to the Championship via the Play-offs.

Northampton Town

On 9 August 2011, he re-joined former Peterborough United manager Gary Johnson at League Two club Northampton Town on a one-month loan.^[6] Later that day, he made his debut for Northampton Town in a shock 2–1 win over Championship side Ipswich Town at Portman Road in the League Cup first round. He came off the bench to replace Bas Savage in stoppage time.^[7] After a difficult first season, Langmead came back the following season, fitter and stronger with a point to prove. This led to Langmead being made captain as the team pushed for a top 3 finish. Devastatingly for Langmead he suffered a Knee injury that not only kept him out of the play-off final against Bradford City, it also would see him not start again for the club for a further 18months. When Langmead returned, there had been a lot of change at the club, including the manager, and it was time for Langmead to leave and get a fresh start.

Non-league

After leaving Northampton Town by mutual consent, Langmead dropped into non-league football.

After a spell at Ebbsfleet United, he then spent a season-long loan at Kidderminster Harriers, before joining Nuneaton Town in the summer of 2016.^[8] He spent 2 seasons with Nuneaton.

In July 2018, Langmead joined Harrogate Town on a free transfer, where he helped them reach the National League Play-offs.

After one season with Harrogate Town he joined local side Brackley Town in the summer of 2019. Langmead didn't play as much as he would have liked and left the following summer.

In July 2020, Langmead joined Banbury United. Although Langmead's first season with the club was cut short due to the pandemic, he helped them reach the FA Cup First Round for the first time in over 40years. Langmead returned the following season to help the club win the Southern League Central Title by 23 points. He was also part of the defence with the best defensive record that season. Again like the previous year, Banbury reached the FA Cup First round, thanks to Langmead's winner against Bath City in the previous qualifying round. After considering retirement, Langmead's success at Banbury led to him signing on for his 3rd season. However, Langmead's start to his 3rd campaign suffered a blow in the week leading up to Banbury's first ever season at Step 2. Langmead suffered an Achilles injury which kept him out until December. Refusing to throw the towel in Langmead returned against Brackley Town on Boxing Day. His first start came against Hereford United where he scored 2 goals as they won 3.2. Langmead would go on to help keep Banbury in the Conference North playing a further 25 games.

In June 2023, Langmead left Banbury, signing for Kettering Town.^[9]
