Grabarz, who took European gold and London 2012 bronze, jumped a personal best of 2.37m at the Lausanne Diamond League meeting in August, equalling Steve Smith's 20-year-old record.
And the 25-year-old attributed his change in fortunes to a fundamental change in attitude having bounced back from having his funding cut in 2011.
And now that his coach, Fuzz Ahmed, has landed at role at UKA's centralised facility at Loughborough University the Cambridge jumper is confident a change of scenery will help him reach new heights in 2013.
"I will be spending a bit of time there in Loughborough," said Grabarz. "But it doesn't change a great deal for me except that it's an opportunity to see more physiotherapists and it's nice to change things up and see new people.
"It gives us a little more direction and there are a lot more opportunities and more people behind the scenes who can help out.
"It's a really good idea because of the success of Team GB at the Olympics and I don't see why it's not a great idea for athletics.
"Whatever you do it is never going to be enough. There is always something you want to improve upon, and I want that British record all to myself.
"Its always frustrating to jump highest not at the big championships but it was my first ever Olympic Games and to perform on such a big stage in front of such a big crowd was a huge deal.
"It was just a matter of committing to my program and not going through the motions anymore. It was about stepping up and finishing everything.
"I got what I deserved in the end and it's given me a taste for success at the top."
Grabarz is currently looking to step up preparations ahead of the World Championships in Moscow, as he bids to outshine Olympic champion Ivan Ukhov on home soil.
But first up for the Diamond League champion will be meets in both Glasgow and Birmingham as part of the British Athletics series - a good opportunity Grabarz feels to lay down a marker.
"It's a really good chance to set a new record in a new stadium and it's a good way to open my season," he added.
"I've been in Birmingham long enough to call it my home and I want to improve on the jump I did there last year."
