Hello hope all are well
We recently purchased a house that was rewired a few years ago. After moving in we decided to change the light fittings (8 months or so later) what I found has confused me and made me think is this allowed?
On the downstairs lighting circuit the porch, hallway, and both receptions room have live feed going to light to next light to next light. The kitchen, utility, garage and toilet have live going to switch to next switch to next switch. If I switch the breaker marked downstairs light off all the downstairs light go off. (So all downstairs on same breaker)
If I take out the live wire from the kitchen switch, the kitchen, garage, utility and toilet don’t work but the rooms that have live to light work.
So I was thinking there must be 2 feeds in the breaker. So I opened the consumer unit and there is only 1 live wire into the downstairs lighting 6am breaker. So what the electrician must have done is made a connection from light to light to light then to switch to switch to switch.
If read somewhere that this could be dangerous, cause reverse polarity etc etc is this true?
Is that allowed, will that cause problems, we been living here for 8 months have had no problems so far thanks

It is perfectly okay to mix live feed at the switch and live feed at the light just as you have. If wired correctly there is no reason to have any reverse polatity or be danderous.
In fact In my own home they flip back and forth as alterations have been made over the years.
