In 2009 they changed their name to St Andrews,[5] and then to Hull United in 2014,[6] when the club was rebranded after Jamie Waltham and ex-pro Jamie Barnwell-Edinboro joined up with John Duffill and Kenny Sayers, adopting a new nickname ("the Citizens") and changing their kit colours to black and white, echoing Hull City's original kit, although this is widely seen as a common misconception.

[8] One of the club's biggest matches came in March 2015 when they played Hull City Under-21s in the East Riding Senior Cup, beating them 3–2.

They kept up their good league form for the rest of the month, recording wins against Penistone, Westella VIP and a 7–0 thrashing of Grimsby Borough, as well as a draw at Hemsworth.

Emley and lead Glasshoughton Welfare before the game was abandoned early in the second half due to floodlight failure.

A few days later they travelled to Selby Town and won 3–1, which meant after 8 games United sat 3 points clear at the top of the league and remained unbeaten.

Mansfield was postponed due to being locked out of Dene Park by Jamie Waltham after he and the club were unable to agree on a lease to play there.

This was to be their last game here as on 13 January the club announced it would no longer be playing at the stadium due to being unable to afford the match day running costs.

It was revealed on 22 January that the club had made a request to groundshare with Brigg Town, however this was rejected by the league, meaning United would have to play their remaining games away until the end of the season or until a suitable ground could be found.

The following game took place almost two weeks later on 13 February and saw them face North Ferriby in the East Riding Senior Cup for the first ever time.

The game was played at South Hunsley School in Melton, just outside of Hull, and ended 2–1 to Ferriby, who fielded a reserve side, knocking United out of the cup.

On 31 March manager Curtis Woodhouse left the club but was persuaded to re-join until the end of the season just a couple of days later, with Paul Foot taking charge of the game he missed.

[14] It was also confirmed on the club website that they had acquired a 10-year lease of the old Endeavour School sports centre, as part of their recently formed partnership with Hull College, starting from the 2016–17 season.

As United were hit hard by an 18-point deduction for three instances of player irregularities and an inability to obtain a ground/ground-share agreement for next season by 31 March deadline,[15] on 21 April the Northern Counties East League decided to relegate them to a lower league designated by the FA as they have not "received a grading certificate by 31st March and not having an alternative proposal approved at the relevant Board Meeting"[1] and as a consequence for this failure.

After a statement was released from the club, it was revealed they will be participating in the Humber Premier League Division one from the 2016–17 season, with Ian Ashbee leaving his role as chairman and Curtis Woodhouse resigning as first team manager.

They finished the season in a very respectable 5th position, however their main success came in the Humber Premier League cup, winning the final on penalties after holding Chalk Lane to a draw in normal time, with Chalk Lane hoping to win the league and cup double for a second season in a row.

The first point of the season came after a 4–4 draw with Cherry Burton in December, with the first league win not coming until February when they beat Hessle Rangers 8–3.

Manager John Duffill opted to appoint a new 1st team captain, long serving player Tresor Kalilwa, in a bid to refresh the culture, mentality and morale following the disappointment of last season.

After a good start to the season, which included a surprise 6–2 win over champions Hedon Rangers, United were drawn against Hull City U23's in the East Riding Senior Cup but were beaten 4–0 in a spirited display.

The first game was against Bottesford Town and attracted a crowd of 431 and the big derby against city rivals Hall Road Rangers drawing in a somewhat disappointing 242.

From 2016, the club played its games at Steve Prescott Centre, the former sports facility of the closed down Endeavour High School.

On 3 May 2023 plans for upgrades to the playing surfaces at Haworth Park were revealed after the club secured a significant amount of funding through grants from The Football Foundation.

Now playing in a higher league United found it tough and would start the season poorly with a draw on the opening day and 3 points from a walkover.
