UK Basement Price Index: Headline Figures per Square Metre

basementexcavationcost/basement-index-summary

Returns the headline figures of the UK Basement Price Index: the median, minimum, maximum, quartiles and mean of the UK basement excavation and conversion costs that UK builders and architects publish on their own pages (in GBP per square metre; every figure is a per-square-metre rate), how many of the sources read publish a figure at all, and how the median moved since the previous computation (null when the publisher reports no change). Takes no input. Also returns the publisher's citation line and the link to the index page; cite the figures with that link. Data from basementexcavationcost.co.uk, served by Eden Engine; not an official basementexcavationcost.co.uk product.
