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

We are currently carrying out essential work in Mary Neuner Road as part of our preparatory work for the PRS on our Clarendon Road site. In order to carry out this work safely, Mary Neuner Road is closed until early March. The road closure is already in place and we have special permission for these closures from London Borough of Haringey Council.

As part of this work we will be carrying out venting of the old pipework under the road. This venting work will take place from Monday 11 February to Friday 22 February, and at times during this venting you may hear the occasional loud noise. Our venting work can last for around 15 to 30 minutes at a time and will take place between site working hours (8am to 6pm). Please do not be alarmed, this is completely normal, and any noisy work will be short and take place within our working hours.

We’re doing everything we can to minimise disruption to our neighbours and we’re liaising with the council, local businesses and resident on a frequent basis.

We have placed signage in the immediate area about the road closure and this will be maintained on a daily basis, to ensure that it is visible to road users and the local community.

Thank you for your patience while we carry out this essential work.
