Herts police's Welwyn Garden City headquarters is set to undergo a major redevelopment after a £70 million investment was given the go ahead.

Approved by Hertfordshire police and crime commissioner David Lloyd, the investment will see a new building constructed at the Stanborough site.

As part of the redevelopment, several 1960s buildings are set to be demolished later this year, having exceeded the end of their designed life and having issues with flooding, heating malfunctions, IT infrastructure and asbestos contamination.

After analysis requested by PCC Lloyd, data revealed that rebuilding on the existing site was the most cost efficient option, with the renovation of existing buildings far more costly.

"This is all about ensuring that the people of Hertfordshire continue to get the very best policing service they deserve," said PCC Lloyd. 

"We now have a record high number of officers in the constabulary, and I am pleased to announce these new facilities will maintain that momentum of investment.

"The people who will work in these new buildings will play a core role in delivering the best frontline policing service, as expected by the public.

"Committing to this once in a generation opportunity is not a decision I have taken lightly but this is a tremendously positive and cost effective step for policing and keeping people safe.

"These aging buildings are no longer fit for purpose and have developed serious faults which would require expensive maintenance, remedial work and energy costs just for them to be kept open.

"This new environmentally friendly facility is a key part of the estates strategy, which is also committed to retaining operational police stations in every district and borough across the county.

"Together with the extra officers this will ensure Hertfordshire Constabulary is fit to respond to the challenges facing a 21st century police service."

Chief Constable Charlie Hall added: "This much needed development will provide modern and efficient facilities to help deliver effective future policing for Hertfordshire.

"The much improved facilities will be more cost effective, assist our recruitment and improve our effectiveness given the far better and more sustainable working conditions for our staff."

A full planning application for the redevelopment has already been granted by Welwyn Hatfield Borough Council.
