Best Place to purchase Paint?

Decorating centre online will mix paints to match known brands and cheaper. Can also harden paints and alter finishes to suit. Highly recommend them. Standard off the shelf paints, I use Brewers. Leyland paints, as someone has said, are good

Virtually every independent painters/decorators stores in my city have long closed.

The choice I have is The Range, B&M and the usual DIY stores.

The door frames/skirting I did with Crown white gloss, anti yellowing paint. Excellent. Will use again when I need to redo, if still available. [Looks like some form of acrylic paints have replaced those]

You can get away with cheaper emulsion paint, but I'd go with good quality gloss every time (edited)

Dulux Trade High Gloss Brilliant White

From screwfix will be cheapest. Use it all the time.

Where you based ? Lots of towns / small shopping centres have discount / poundsaver style DIY stores that sell everything including paint most of which are just damaged tin and a fraction of the price they sell in Screwfix / B&Q etc. (edited)

The wall would be the best place mate, ceiling be second best

You can do the floor too but I’d advise against

Cheers
