These figures were updated on Feb 10th 2004. They are for estimating purposes only and must be used in conjunction with the guidance notes. If you live in Northern Ireland, the cost of building work is considerably lower than in the rest of the UK and you should seek local advice. As an indication, use the figures for Mids, Yorks, NE & Wales and deduct 20%. If you live in the Channel Islands, London is the most appropriate comparison but local conditions affect building costs and you should seek local advice.
