In 1988, the business was enlarged and two part time engineers were employed, investment in new equipment was made and annual turnover nearly doubled. A year on year increase in business continued until 2001, when the Foot and Mouth epidemic drastically curtailed outside events and led to a diversification of the company activities. Reliance on outdoor events, which tended to be seasonal (April through October), had to be reduced.

In the autumn of 2001 Event Sound Services started to undertake permanent installation work in restaurants, offices and factories of public address systems, telephones systems and Cat5e cabling. Both permanent engineers also gained City and Guild qualifications for P.A.T. ( Portable Appliance Testing ) testing.

Further increased business meant that by 2003 the company comprised of two permanent engineers, three part time engineers and an office manager. Event Sound Services also works in conjunction with F.T.S. a company providing computer services and the installation of specialist high quality home audio visual equipment and telephone systems for home or office including least cost routing packages.

In the spring of 2004 Event Sound Services introduced a 24 hour nationwide maintenance package for installed public address systems to further increase their services to the industry.
