It’s not a fair comparison then is it? $80/hr is an expensive but not outrageously so handyman, plus they have their own tools to purchase and maintain and other business operating overhead (fuel and transportation maintenance) etc.

DIY—if you’re able—is always less expensive.

quoted £245 for a handyman to come in and do the three hour job

Power tools, hand tools, clothes, batteries, heavy painters cothes, gloves etc.. do not make the job.

The skill of the handyman who can quickly and efficiently deduce an effective solution (described vaguely by a couple of photos and a description over the phone by someone who doesn't know shit about the problem they need solved) to a carpentry/handyman repair and do it within 3 hours is what makes the job.

People often make the point about learning home repair as a way to save money, and true it definitely is a necessary skill to some degree as a home owner unless you have a lotttt of money... but learning to do your own home repair really isn't "saving money" so much as simultaneously devaluing your free time AND labor time to the point that all of the incurred debt is inscribed into your body and lost time with your family or friends rather than in invoices for repairman. This leaves me hesitant to call doing a significant portion of home renovation yourself ON TOP of holding down a full time job "saving" anything even if it helps keeps monetary expenses down.
