Cranbrook is located to the East of Exeter, in close proximity to Exeter Airport has already seen rapid development, with 1,800 new homes built and occupied, two schools for more than 1,400 pupils completed, a railway station and neighbourhood centre together with country park completed by the end of 2019. The Cranbrook Development Plan Document allocates land for around 6,500 additional homes and 18,000 or more residents. In addition, the Second New Community proposed within East Devon is located within the Cranbrook Leisure catchment area and proposes up to 10,000 new homes. In October 2024 East Devon District Councils (EDDC) Strategic Planning Committee endorsed a masterplan for Cranbrook town centre. The masterplan sets out where the main uses will be located and high-level principles for the form and feel of Cranbrook town centre. This masterplan identifies a site for the Leisure and Health and Wellbeing Centre at the southern end of the town centre, north of Badger Way. The chosen site seeks to locate the leisure facility adjacent to the health and wellbeing centre, with the facilities connected by Public Realm. The site allocated for the Leisure, Health and Wellbeing Facilities is located at the southern end of Cranbrook town centre, north of Badger Way. The site is large enough to accommodate a leisure centre with swimming pool (including Learner Pool),100 station gym, 2 studios, 1 spin studio, soft play and cafe. It will not, however, include a 4-court sports hall. A Feasibility Study for the Leisure Centre and Library, Youth and Family Hub is being led by East Devon District Council and is due to complete in the Autumn. A similar Feasibility for a Neighbourhood Health Centre is being led by the NHS and working to a similar timeframe.

East Devon District Council (EDDC) is seeking to engage the market in advance of procuring a long-term Energy Services Company (ESCo) to deliver a new District Heating Network to serve the expansion areas of Cranbrook. The scheme will serve the growth of Cranbrook new town, supplying low-carbon heat to approximately 4,500 new homes and 24,500m2 of commercial space, including three new schools. The project has successfully secured a £5.95 million capital contribution grant from the Green Heat Network Fund (GHNF), administered by Triple Point on behalf of the Department for Energy Security and Net Zero. This funding is intended to support the delivery of low-carbon heat infrastructure and will be made available to the appointed ESCo as a contribution towards eligible capital works. The scheme will be required to meet Future Homes and Future Building standards as set out in the updated building regulations. Planning consent for the network has already been secured under East Devon District Council's Local Development Order (LDO) for district heating, adopted in July 2020. Additionally, the Cranbrook Plan has allocated two hectares of land for an Energy Centre and associated heat network plant and equipment within the development. The new heat network will include heat distribution pipework, and a new heat generation source. The estimated annual heat demand from the new development is 27.4 GWh, with a peak demand of 14.8 MW. A feasibility study has been carried out that has built the technical and economic case for the expansion. The successful bidder will need to develop the design to construction stage. This will involve coordination with the developers and their network builders/operators. The successful bidder will then operate and maintain the network for the duration of the contract in line with industry best practices and the Heat Trust Scheme Standards with a subsequent move to market regulations where applicable. The given contract end date is indicative of the construction end, the expectation is that the successful bidder will then operate and maintain the network for a period of circa 80 years.

The project is the expansion of the Cranbrook district heating network in East Devon, to supply heat to new development areas of an additional c4,500 homes and 24,500m2 of commercial space including 3 new schools at Cranbrook new town. The project will benefit from decarbonised heat by connecting to an Energy from Waste facility (EFW) in Hill Barton via an interconnect pipe to SkyPark energy centre “The Interconnector Project”. The interconnector will support the planned expansion of the Cranbrook new town through enabling the delivery of a Future Homes/Buildings Standard compliant energy solution. The project team have developed good working relationships with the Developers of the new homes and commercial spaces at Cranbrook as well as E.ON, the owner and operator of the existing network. The project will be delivered by an ESCo. EDDC will act as broker and facilitate the procurement of the ESCo. The procurement will be carried out by the Cranbrook Developers. Planning is already in place via the EDDC Local Development Order (LDO) for district heating dated July 2020. The proposed expansion area network length is anticipated to be c.98.6km, which will need to be installed by the ESCo. The total heat demand is estimated to be 34.05 GWh/yr, the anticipated diversified Peak demand for the expansion area is 12.5MW. An estimated 96.9% of this demand will be met by three EFW units, and an anticipated 3.1% from the existing gas CHP at Cranbrook Energy Centre. The total CHP heat capacity is approximately 10.4MW. The scheme includes thermal storage plant of a capacity of approximately 900m3 which will be located in the vicinity of the Cranbrook energy centre. This location is identified within the adopted Cranbrook plan. The intention is to secure additional carbon savings through further avoidance of gas CHP.

Early Engagement - Currently we are looking to have all design drawings in place for the 3rd September. we have had early agreement on the basis of design so we hope to pull this date forward to 3rd August. We are looking for the contractor to express interest in the works and by doing so will ensure they will have estimating team ready for August -September when the tender documents become live. The contractor will also ensure there will be availability within their programmes to commit to the works target date of 7th October at the latest. Phase 1 completed in July 2024 . Phase 2 target start date 7th October 2024. Works involved installation of 150m linear length Anchored sheet pile wall with deviation around concession buildings. Sheet pile lengths between 9.5-10 metres. Rock anchors on every In-pan length of anchors 18m. As part of this early engagement see attached phase 1 drawings which will serve as the basis for the phase 2 design but are not to be priced against. I have also provided the alignment for phase 2. There are 2 concessions to pile around, and a third area where a (Coastguard building) concession once stood. As part of the design process we are trying to establish if these areas can be built as a cantilever rather than require anchoring. The sheet piling around the third area is still subject to change.
