Nathan Jones felt his side put in a "professional performance" as they defeated Accrington Stanley 2-0 at the Wham Stadium
James Collins gave the Hatters the lead with a tap in from an Olly Lee header before Danny Hylton netted from the penalty spot after Alan Sheehan was fouled just before half-time.
The result means the Town move up to third having picked up five wins in their last six Sky Bet League Two matches.
Jones said: "It was a real professional performance away from home against a side that started above us going into the game. It's a difficult place to play – these are always a good side, Stanley, at this level. To come here and be relatively comfortable, a 2-0 win, I am delighted."
The first goal came just after the first real chance of the game when Lee saw his effort saved – the move continuing and eventually seeing Collins put the Hatters in the lead.
"We had a littlle bit of pressure there, it was a great ball in, a great rise from Olly Lee – we've seen him do that in pre-season at Boreham Wood – and then to Collo who is Jonny on the spot in terms of that back post area," Jones continued. "We are not worried about that sort of stuff (getting first half goals). We score and we keep clean sheets that's all we are worried about.
"We are relatively high scorers, I'd be surprised if we're not the top scorers in the league. So we know whether we take it first half, second half, 80th, 90th, 98th minute, we don't care. The level of performance today showed professionalism. The second half wasn't the most entertaining game, it wasn't as fluent. We did all the ugly stuff you have to do to win games away from home, especially when you come to difficult places."
