Reduction in electrical work

Hourly is safer and leaves less room for error , if you find a problem and the job takes longer then the customer will pay for the time...

I personally feel much more comfortable working by the hour

Mostly I'll quote for a job unless it's very difficult to gauge how long it'll take or fault finding.
The only downside with working on an hourly rate in my view is that I feel under pressure to deliver good value for money and prove integrity so probably feel under more strain.
