Sian Howard

I work within the Property Services team, having transitioned from the Investment Support team in 2026. 

Before joining the Development Bank of Wales, I built a strong professional background in Law, specialising in Residential Conveyancing.

I am passionate about supporting homeowners to make energy‑efficient improvements to their homes. By helping people reduce their energy costs and carbon footprint, I contribute to creating warmer, more affordable homes and support Wales’s transition to a greener, more sustainable future.
