Promotion to League Two was confirmed on 15 April 2014 after nearest rivals Cambridge United failed to win; Luton eventually ended the season 19 points ahead of them.

Victories over higher-league opponents Wolverhampton Wanderers and Norwich City in the FA Cup gave some respite, but "genuine personal reasons" saw Paul Buckle leave the club in February.

Under his replacement, John Still, performances and results gradually picked up to culminate in a late five-game unbeaten run, but the club could not challenge for a play-off finish and ended the season in a club-record low of seventh place.

[5] He later released three more, transfer listed five others, and then signed players he had either worked with or scouted previously at Dagenham & Redbridge in the form of Solomon Taiwo, Scott Griffiths, Alex Wall and Elliot Justham.

[13][14][15][16][17] The opening of the transfer window on 1 July saw Southport players Andy Parry and Shaun Whalley sign for undisclosed fees, and out-of-contract Histon duo Danny Fitzsimons and Jim Stevenson also join the club.

[20] Transfer-listed goalkeeper Dean Brill moved on loan to Scottish Premier League club Inverness Caledonian Thistle on 2 July until January 2014.

[26] Luton's first team played a number of local friendly matches, winning two and losing one, before hosting Premier League club Aston Villa at Kenilworth Road on 23 July.

[31] After video evidence contradicted the referee's assessment of violent conduct, McNulty's red card was overturned on appeal in time for the match against Salisbury City three days later.

[33][34] Luton then drew 0–0 in consecutive matches with title favourites Forest Green Rovers and league leaders Cambridge United to leave themselves in 14th place in the table.

John Still acknowledged his team's lack of goals in their opening five games and, combined with injuries to strikers Mark Cullen, Jon Shaw and Alex Wall, he signed prolific forward Paul Benson on a season-long loan from League One club Swindon Town on 26 August.

[39] Youth team graduates Jerome Jibodu and Jake Woolley both joined Conference South club Boreham Wood on three-month loans on 6 September.

[43] The previous season's player of the year Alex Lawless made his first start on 17 September upon returning from injury, inspiring Luton to a 3–0 win over Dartford in which he scored one goal and set up another.

[44] After impressing in youth team and development squad games, 17-year-old striker Zane Banton signed a two-year professional contract with the club on 19 September.

[52] A hat-trick from Andre Gray and a goal from Luke Guttridge saw Luton beat basement club Hyde 4–1 on 12 October to extend their unbeaten run to seven games.

[53] Injured defender Garry Richards, who was yet to make an appearance for the club since signing in the summer of 2012, was released from his contract on 14 October and announced his retirement from football soon after.

[55] The club were involved in another high-scoring game on 19 October, winning 4–3 away to Tamworth with two goals from Paul Benson and long-range strikes from Jonathan Smith and Andy Parry.

[57] The club returned to league games on 2 November, drawing 0–0 with Gateshead in weather described by manager John Still as "as bad conditions as I can remember a team playing in".

[65] On 28 November, injuries to defenders Anthony Charles, Alex Lacey, Andy Parry and Steve McNulty, coupled with the impending closure of the loan transfer window, saw the club act to sign three defenders on loan: Joe Davis arrived from Port Vale, Alfie Mawson from Brentford, and Pelly Ruddock Mpanzu, who was also able to play in midfield, from West Ham United.

[70] The club then won their ninth home game in a row on 21 December, beating Gateshead 4–2 to move just one point behind league leaders Cambridge United.

[74] Despite the setback of potentially losing Smith for the rest of the campaign, Luton went on to record their then-biggest victory of the season on 28 December by defeating Kidderminster Harriers 6–0 in front of 8,488 people at Kenilworth Road, which moved the club into first place in the table.

Luke Guttridge and substitute Jake Howells scored two apiece, with goals also coming from Paul Benson and a first for the club by full-back Scott Griffiths.

[76] On 30 December, midfield loanee Pelly Ruddock Mpanzu was recalled early by his parent club West Ham United to cover their injury crisis.

[77] Luton began 2014 with a 2–1 home victory over Barnet, their seventh consecutive league win, in wet conditions on New Year's Day that almost saw the game abandoned.

[78] With midfielders in short supply at the club, John Still moved on 3 January to sign Peterborough United's Kane Ferdinand on loan until the end of the season.

[84] The next day saw a busy period of transfer activity, as Welling United defender Fraser Franks was signed for an undisclosed fee on a contract until July 2015, while fringe players Alex Wall and JJ O'Donnell were loaned out to Dartford and Gateshead respectively for one month.

[90] On 28 January, former loanee Pelly Ruddock Mpanzu signed permanently for Luton from West Ham United on a two-and-a-half-year contract for an undisclosed fee, in a transfer described as a "major coup".

An Andre Gray hat-trick and goals from Paul Benson, Jake Howells, Pelly Ruddock Mpanzu and Alex Lawless placed the club nine points clear at the top of the table.

Luton went 1–0 down – the first time they had been in a losing position in a league game since October – but a late equaliser from substitute Mark Cullen resulted in a 1–1 draw and left the club 15 points clear at the top of the table.

[117] The club made it 15 consecutive away league games unbeaten with a 2–1 win at play-off chasing Grimsby Town three days later; Robinson and Benson were again on the scoresheet.

[127] The final home match of the season two days later saw Luton run out as 4–1 victors over Forest Green Rovers, with Andre Gray scoring his 30th goal of the campaign.
