Tens of Hours Wasted! UV light, paint,etc

Lardness

Been living overseas about 15 years. Bought a UK house last year- and started decorating. Lick of emulsion, but lots of gloss, white paint (Dulux Once)....13 doors and a few hundred feet of skirting. It's spring, so thought I'd finish off the white work. I couldn't believe how yellow the paint from Sep last year was compared to the new. So, quick google search, EU regs, 2010, VOC content, UV light, etc, etc.
So, I'm going to start again on the white using water-based gloss. I know a high adhesive primer will be required (Zinsser seems to be pretty good), with maybe Leyland Fast Drying Gloss on top.
What I'm really not keen on is rubbing down the existing gloss......difficult profiles/cross sections to sand, carpet already in place (unable to move).
So....can I get away with the Zinsser primer alone? The attached pic shows a radiator in an interior bathroom painted in Sep last year with a stroke of the same paint this morning

I've found water based white paint yellows over time. Not as bad as oil based... Next time I paint the woodwork throughout, I may well go for another colour.

Perhaps better to use proper radiator paint 🤷‍♀️ Rather than normal paint

Use Dulux trade quick dry gloss for the woodwork and equivalent trade for rads. Costs a bit more but easier to paint and goes on better imo

The pic of the radiator was used just because it was quick & easy. All of last autumn's white paint is the same......not just the radiator .......skirting boards & doors

Dulux Trade Satinwood doesn't yellow.

Nor does Dulux Diamond oil based which is far more hardwearing than the water based products.

I did my whole house 4 years ago in Dulux Trade Satinwood.......16 doors, 15 rads, skirtings, door frames etc. No yellowing at all. Highly Recommended.

Being an MSE person, my recent white wood decorating has been with Wickes trade quick dry satinwood.
Cheaper than Dulux or Crown trade, and better than Dulux or Crown standard quick dry. The best thing about it is that you can go over it again, and not see all the brush strokes like you can with some water based paint ( as long as you are reasonably quick ) .

OP - A lot of the painting was direct onto old oil based gloss . I lightly sanded but did not use any primer.
The first coat was not that great, but looked OK after a second/third one. Probably a bit of a shortcut way of doing it but got away with it !

Did you wash down paintwork with sugar soap and use a undercoat prior to painting, it is the best way to keep paintwork white. Your previous owner may have been a smoker, used diffusers or cooked in such away that residues where on the paintwork.

I used Zinsser 123 & then a couple of coats of Leyland water-based gloss. Very happy with the rsults
