Low hot water pressure after pipe changes

[Leakypipes]

Evening all.. can anyone help me please?? today I cut & reconnected both the hot and cold feeds in the kitchen due to new position of sink. Ive capped off the feeds with push fit until the sink arrive ie no tap is connected/not pulled water through yet. Mains pressure back on, but got terrible hot water pressure now. Bar gauge showing 1.5. No fault codes. Valiant 831. Hot water pressure fine this morning! Any pointers?? help..

At a guess was the cold stop tap not fully open?
