When looking to overseed bare patches in shady areas of UK lawns, several grass seed options are particularly effective due to their shade tolerance.

1. Hard Fescue: Known for its upright growth, hard fescue is highly tolerant of shade, drought, and poor soil conditions. This grass variety can be a robust choice for those looking to establish a resilient lawn in less sunny spots. More detailed information can be found in a comprehensive guide on DIY Gardening.

2. Perennial Ryegrass: Often recommended as a companion grass, perennial ryegrass is valued for its excellent shade tolerance and dark green color. This grass seed can thrive well in shaded conditions, making it an ideal candidate for overseeding. For further insights, refer to The Grass People.

3. Specialized Shade Mixtures: Products such as the "Premium Shade" mixture from Lawn UK are specifically formulated for high-quality grass growth in heavy shade. This could be an excellent choice for ensuring a lush lawn in particularly dark areas. Check out more about this mixture on the Lawn UK website.

4. Fine Fescues: This category includes creeping red fescue, Chewings fescue, and hard fescue, which are touted for their excellent shade resistance. They are ideal for lawns that experience significant shade throughout the growing season. You can read more about these grass varieties on Lawnsmith.

5. Premium Shade Grass Seed Mix: Another recommended product is the premium shade grass seed mix that contains a blend of grass types designed to thrive in shaded or wet areas. This mix promises to create deeper roots, ensuring survival and growth in challenging conditions. More details are available on Relentless Gardener.

These options provide a robust foundation for overseeding in shady areas, maximizing growth potential and ensuring a lush appearance in those less sunny parts of your lawn.
