February Project Update

February project update

Sizewell C is continuing work along Lover’s Lane, the Ancillary Construction Area on King George’s Avenue and the Main Development Site. You may have noticed our contractors are trimming back hedgerows around the Sizewell C site and this work will also continue over the next month.

We have recently written to residents along the B1122, highlighting the upcoming resurfacing work to improve the condition of the road, which will reduce noise and vibrations generated from traffic. These works will be undertaken on sections of the B1122 between the junction with the A12 and the junction with Abbey Lane in Leiston. We expect the work to start week commencing 18th March and we anticipate it will be completed by 14th April 2024 (subject to weather conditions). We will write to confirm the schedule and outline traffic management before work begins.

The online works tracker will also be updated https://www.szcworkstracker.co.uk/

Construction update

Current activity on site and across a number of Associated Development sites is concentrated on ecological and archaeological works on site, as well as conducting ground trials for civil engineering works and commencing drainage and earthworks. We’ll be working on access roads on site so that construction traffic can get direct and efficient access, and we’ll establish perimeter fencing so that we have safe and secure site boundaries. We’ll also start on the construction and fit-out of our early site welfare and site offices, so we’ve got the right facilities in place for our team.


We have now held three inaugural forum meetings including the Main Development Site, Northern Transport Forum and the Southern Transport Forum, and thank all attendees for their contributions. The agendas and slide packs can be found on our webpage Community Forums - Sizewell C. The minutes from the meetings are with forum members and will be formally approved at the start of the next meeting, then published on the East Suffolk Council website.

The Sizewell C forum will run annually, the first meeting will be held on Tuesday 9 April (please note the date has been amended to avoid a clash with the Easter bank holiday weekend). For further information please visit our website: https://www.sizewellc.com/community/forums.

• The Main Site Forum will meet on Tuesday 16 April.

• The Northern Transport Forum will meet on Wednesday 8 May.

• The Southern Transport Forum will meet on Wednesday 15 May.

• Venue and time details can be found on the website.

HGV movements and notifications

Local communities are encouraged to sign up for email notifications in advance of wide load movements during the construction period. If you’d like to receive these notifications, simply get in touch with our Community Relations Team info@sizewellc.com to register.

There are designated routes for HGV movements which are monitored by our Traffic Management Team who brief our contractors of their travel obligations. We have also put signs in place across the region and in Leiston to direct our traffic. This process is working well, however, if you see any HGVs that you believe are not complying, please get in touch via info@sizewellc.com or 0800 197 6102.

Please find below a copy of the presentation by The Sizewell C Community Relations team and a copy of the documents referred to during the evening 27th October 2023:


The Deed of Obligation

As presented on Friday, the Deed of Obligation  details the commitments made for mitigations to areas such as tourism, traffic, blue light services etc. 



The Freight Management Strategy details our plans to deliver 60% of materials by Rail and Sea to reduce the HGV numbers on the roads at the peak of construction.

The Consolidated Transport Assessment details the modelled impact on local roads, shown by road and timings throughout the day and phase of construction.

The Construction Worker Travel Plan shares full details of the plans, including the facilities at the park and rides and enforcement. 

The Worker Code of Conduct purpose is covered in the Community Safety Management Plan, the final Worker Code of Conduct is currently being finalised. 

The Traffic Incident Management Plan details the plans in the event of traffic issues on the A12. 


The Beach Landing Facility

The plans for the Beach Landing Facilities can be viewed here: PowerPoint Presentation (planninginspectorate.gov.uk) (Part 1) and here PowerPoint Presentation (planninginspectorate.gov.uk) (Part 2)

EN010012-007571-Sizewell C Project - Other- Volume 2 Main Development Site Chapter 3 Appendix 3D- Construction Method.pdf (planninginspectorate.gov.uk) For details on the Construction Method, see section 3.1 on Page 22.



EN010012-002231-SZC_BK8_8.10_Accommodation_Strategy.pdf (planninginspectorate.gov.uk) (Please see from page 18 for consideration of the impact on tourist accommodation)


SZC Co. cannot directly control the accommodation choices of the workforce; many workers would not be directly employed by SZC Co. and cannot be compelled to live in any given location. However, SZC Co. would assist workers in finding suitable accommodation, both in terms of its type and location.


As set out above, there is a significant stock of homes and bedspaces in the sector – in 2011, there were over 99,000 bedspaces in the area, and based on national and regional average increases this may have since risen to over 128,000. As such, Sizewell C workers are likely to require around 1.2% of all bedspaces in the area. This is well within the overall calculated level of frictional vacancy within the sector, and is therefore expected to be imperceptible at that scale.


The strategy details that:

− Over a third of the workforce are expected to live locally
− Up to 3,000 workers could occupy an accommodation campus and caravan park provided by the Sizewell C Project.

− Around 800 workers would be expected to seek tourist accommodation in a range of types (e.g. serviced, self-catering, caravans) depending on price, location, and availability.

− Around 1,200 workers would be expected to seek tenancies in the private rented sector (similar to levels of private renting during the peak of Sizewell B).

− Around 880 workers are predicted to buy accommodation (owner-occupied sector), including NHB operational staff making a permanent move to the area and workers in long-term construction and support/management roles.


This breakdown is considered to be an upper estimate as it does not include workers seeking spare rooms in existing homes, or in currently unregistered accommodation known as ‘latent accommodation’ – this type of accommodation has proved popular at Hinkley Point C.
