Datum Lines And Floor Level

Jed,
Welcome to the forum and just to pacify our outside of Manchester visitors, we will be very pleasant and generous to all if we ever do take over the planet. That’s another post though.
In answer to your question, first determine the height of the cabinet + plinth + floor finish. Then draw a datum line around the fitting area. Although you will be measuring vertically from the datum line to the floor this will give you a good enough indication of how far your flooring is out.
If this is outside of your acceptable tolerance, (I would advise no more than 10mm) consider re-levelling the floor first. If not, find a mean height and work from this point. It may mean that you will have to scribe the plinth in locations but it will be acceptable unless you are seeking perfection.

Jed,
You failed to mention how generous you would be if Mancunians did run the planet but I expect this was just an oversight and you would dole out generosities by the bucketload if you were to form part of the interplanetary Mancunian government.

Jed, It’s sad that you seem to consider perfection a downfall but as it is a secondary income and you are taking on more work of this type then a faster perfection will develop.
Perfection is a creditable asset yet is sometimes lost on a frustrated, anxious consumer who may not comprehend that true perfection takes time.
I’m uncertain as to the availability or, more importantly, quality of kitchen fitting courses anywhere in the UK at present but the best way to learn any trade is to study a professional at work. Perhaps you could approach a quality kitchen installer and ask that you accompany him on a job.
Training would be both effective and free.
Having the right tools for the job is expensive as a kitchen installer but it is vital for a quality finish. Added to this you will have to be aware of the regulations surrounding gas and electrical work if you wish to multitask as an installer. Many now employ the services of others to undertake this work.
Whichever way you choose will prove both expensive and sacrificial but look on the bright side here, if you do form part of the interplanetary Mancunian government, you can give yourself a grant to fund your ambitions.
We look forward to your future posts and contributons and good luck with your aspirations.
