We continued the search for single pulses (SPs) in the northern part of the all-sky High Time Resolution Universe survey, whose aim is to detect pulsars and other radio transients. This search is now about 21% complete and yielded the first discovery of a fast radio burst (FRB) with the 100m Effelsberg Radio Telescope. FRB 20110220A is detected with an S/N optimised dispersion measure of 501.0pc/cm^3^ and width of 11.9+/-3.5ms giving it a fluence of 0.6+/-0.1Jy.ms. We obtained the first the first L-band detection of the rotating radio transient (RRAT) J2028+28, from which upper limits on the source's period and burst rate are obtained, as well as an improved position. The discovery of a new RRAT, J0404+53, is reported previously identified as an isolated SP candidate by Houben et al. (2026A&A.707A..10H, Cat. J/A+A/707/A10). Eight new SP trains and 272 faint isolated SP candidates were detected. The latter could be used to show the presence of a Galactic latitude and longitude dependence on the all-sky detection rates of the isolated SP candidates. This direction dependence suggests the existence of a faint Galactic SP population.
