Moving to UK from Canada

I recently got my Irish/EU passport and live in Canada. I’m not keen on moving to Ireland because of the high cost of living and the housing shortage. I’ve thought about moving to the UK since I’m eligible to work and live under the Common Travel Area agreement. I only speak English, and I’ve heard that finding work in other EU countries might be challenging due to language barriers. What’s the best approach to finding immediate work in the UK? I have experience in customer service and web design. Should I start by sending my resumes to recruiting agencies, or would it be better to move there first even though it’s risky to quit my job and go with nothing lined up. I don’t have too much in savings. I’m feeling a bit lost on how to do this.
