Got a diy dude via neighbour hood app to place some lawn edging and before hand asked his rate and was told £ 50 flat rate and I assumed it meant either for one job or minimum cost for appearance and as I was busy left it with my husband and thought to check out his skills and pricing by having this job done which he did excellent and worked full day yesterday and today 3 hours but was shocked when charged £ 600. Have I been taken for a ride ? I usually pay £ 25 for DIY jobs and just feel a bit unprepared for these billing but paid and learned hard lesson of need to sort fixed price for a job instead of hourly rates and still in the dark on exact definition of flat rates
