They never quite say what they mean.
These books translate it.

A funny, no-nonsense guide to British & Irish English — for people moving to, working in, or just baffled by the UK & Ireland. Because "not bad" means very good, and "that's interesting" means absolutely not.

That's Brilliant book cover

A quick translation

What they say  →  what they actually mean

"Not bad"Actually, very good
"That's interesting"I completely disagree
"With all due respect…"I'm about to insult you
"I'll bear it in mind"I've already forgotten it
"You must come for dinner"(This is not a real invitation)
"Quite good"Genuinely a compliment
"Sure, it'll be grand"(Irish) It's fine, stop worrying
"I'm not being funny, but…"I'm about to be very funny (rude)

…there are a few hundred more where that came from.

About

Written by Colin Hartley — with a soft spot for the gloriously indirect way the British and Irish speak, and for everyone who's ever nodded along to "you alright?" wondering what on earth they were being asked.
