The outstanding personality of the years after the 1939-45 war was Ian Kilgour, captain from 1948 to 1950. In the 1949-50 season, having played through all the SRU trials, Kilgour came close to being Kirkcaldy's fourth cap. Most critics of the time believed he should have been in the national team but instead he remained as travelling reserve. After having served the club as its president Kilgour became the Midlands District representative on the Union committee.

The Midlands league failed to resume after the war, apparently because many claimed it encouraged negative play. Sides like Kirkcaldy therefore had to content themselves with a diet of friendly fixtures. Most seasons produced more wins than losses but Kirkcaldy remained unable to force themselves onto the fixture lists in the Borders, Edinburgh and Glasgow.

The shared pavilion with the cricket club produced a series of disputes about responsibility for breakages and repairs. This encouraged the rugby club to seek facilities elsewhere in the town, at Dunnikier Park for instance, where the new Kirkcaldy High School was shortly to be built. Shortage of finance precluded any move but ultimately the situation resolved itself when the cricketers moved to Bennochy.

Slowly playing standards improved with a marked improvement in the quality of fixtures and greater attention being paid to fitness and techniques. By the late 1960's Kirkcaldy was generally considered to be one of the better sides outwith the unofficial championship, then run by various national newspapers.

Playing numbers grew appreciably thanks to the numbers recruited from Kirkcaldy High School, then one of the strongest rugby schools in the district. A fourth team had a full fixture list by 1964 and within a couple of years a sixth side had a full fixture list.

Suggestions had been made regularly from the mid fifties that the club should acquire premises in the town for conversion into clubrooms and bar. These came to nothing until the departure of the cricket club changed the situation. The Beveridge Park pavilion, now wholly owned by the rugby club, underwent a transformation in 1968 into a clubhouse with bar and tea room. Plans for new changing rooms were drawn up soon afterwards and eventually opened in 1971. Welcome though the new clubhouse was it proved to be inadequate for a rapidly expanding club and extensive fund raising in the mid seventies provided the £30,000 needed to construct the present clubhouse.
