Refurbishment of the whole estate was commenced in partnership with Your Homes Newcastle (YHN), the social housing arm of Newcastle City Council. The work was undertaken by Mansell, a division of Balfour Beatty. The work involved careful reinstatement of original features and colour schemes, using modernised materials where possible, while retaining the look and feel of the 1970s design scheme. For example, a new coloured aluminium window frame was designed to allow for improved security and insulation, without compromising the visual impact of the buildings. The most recent phase of this was completed in June 2008. A bid for PFI funding from the Homes and Communities Agency (to the value of £80 million) was sought in June 2009 to fund the project, which was estimated to cost £210 million, but was rejected as it did not meet the criteria; subsequent negotiations with the Department for Communities and Local Government led to the creation of the Byker Community Trust in 2012.
