Continuous power surges in home?

USA You use the term power surge, but a surge will not dim the lights. Absolutely call the electric utility and report this. However, if they have not had any power supply problems with the lines or transformer feeding your house, you should call a licensed electrician and have all your power, neutral and ground connections checked. Loose or corroded terminations will cause lights to dim, electronics not to work right, etc... I have found loose neutral connections, corroded connections, and even corroded stabs on the back of main circuit breakers that will cause those problems.
