Looks like a Westfire Uniq 23 wood burner. Cool modern design from a good Danish firm. Would be better as a 5kw model imho (it's a 6) due to combustion air requirements in the uk. They do offer a direct air feed or snorkel into most of their fires which is cool.
Little Thurlow on long legs by Town and Country fires. Amazing stove from one of the best U.K. manufacturers. Probably their best selling model too I'd imagine. 5kw output, awesome air controls (spinners) and the option of brass or st st features for the traditional or contemporary home. Looks like a nice install too. Just hope the wooden lintel is not too close to the flue pipe!
