Niamh has specialised in housing law since 1999, acting for local authorities, housing associations, private landlords, tenants and the homeless. She has particular expertise in the areas of homelessness, judicial review, disability discrimination, anti-social behaviour, right to buy, shared ownership, housing fraud and HMO licencing.
Notable cases:

When representing landlords Niamh’s aim is always to find the most practical and cost effective way for her clients to achieve their goals.
When representing tenants she is acutely aware of the need to have particular care to the emotional aspect of the litigation, whether it involves preserving their existing housing rights or addressing their current housing needs.
