Welcome to our website about the regeneration of the former Clarendon Gasworks – Haringey Heartlands.

As work progresses over the next two years, we intend to use these pages to keep you informed of any changes and developments on the site. If you have any questions, or would like to know further details, our experts are happy to talk to you.

Who is National Grid?

National Grid’s role is to connect people to the energy they use. We own and manage the energy network to which many different power sources are connected; our systems keep homes, offices and factories across the country going.

Over the years we have accumulated a number of sites related to energy industry but also shops, offices, depots and residential properties. This includes around 400 former gasworks sites, one of which is the Clarendon Road site. Today we are looking at how we can bring these sites back into use and in London, this means providing space for new homes.

Buiding the new gas pressure reduction station (PRS)

In October 2017 we’ll begin building a new gas pressure reduction station (PRS) at the former Clarendon Road Gasworks and carrying out gas mains work. We expect this phase of the project to be complete by summer 2018.

The new PRS will lie to the east of the site, near to Hornsey Park Road, and will regulate the pressure of gas in the local distribution system. It received planning permission in February this year and will replace the existing PRS with an up to date model.

We have instructed tRIIO, a specialist gas engineering company, to build the new PRS and carry out any accompanying gas mains work. Their operatives will arrive onsite on 2 October 2017, with work initially taking place on the gas mains running underneath Mary Neuner Road.

Our working hours throughout this phase of the project will be 08:00 – 17:00 Monday – Friday.


Mary Neuner Road – Temporary Closure

At certain points between October 2017 and Summer 2018, it will be necessary for us to temporarily close or install a one way system on Mary Neuner Road to allow us to carry out gas mains work. We have been granted special permission for these closures from London Borough of Haringey Council.

We’re doing everything we can to minimise disruption to our neighbours by only closing the road when it is absolutely necessary and we’re liaising with the council, local businesses and residents to find out when it is most convenient for road closures to take place.

When the road is closed to traffic in both directions, a diversion will be in place and will be well sign-posted.
