About NLA

NLA is the membership organisation for the built environment in London. We work with some of the most recognisable organisations across the built environment — including developers, architects, engineers, planners, investors and public‑sector bodies — many of whom are shaping cities in the UK and around the world.

Through insight, learning, debate and high‑profile programmes, NLA convenes senior leaders and organisations to drive better outcomes for London and beyond. Our membership spans large organisations through to individuals and small practices, united by a shared interest in the built environment.

As NLA grows, our strategic focus is on expanding and deepening our organisational and business membership, while continuing to support and retain our wider professional community.

The Growth Marketing Manager will sit alongside our existing Marketing and Communications Managers, with a distinct focus on driving membership growth through acquisition, conversion and retention.

• Converts awareness of NLA’s programmes, research and influence into paid membership
• Owns marketing‑led processes that support membership engagement, retention and renewal across the lifecycle

• Plan, execute and optimise digital campaigns to grow NLA’s membership base, with a strong focus on built environment organisations operating in London and internationally
• Own the marketing‑led acquisition funnel from awareness through to Marketing Qualified Lead (MQL), supporting conversion in partnership with sales and membership colleagues
• Translate NLA’s propositions, programmes, research and events into compelling, conversion‑focused digital journeys for organisational audiences

• Partner with sales operations and membership colleagues to align on target organisations, account‑based priorities, conversion criteria and performance
• Manage relationships with external agencies or suppliers where required

• Track, analyse and report on performance across acquisition and retention activity
• Own and report on marketing and handover metrics including:
  • Marketing Qualified Leads (MQLs)
  • Sales Accepted Leads (SALs)
  • Conversion rates from MQL to SAL and onward to member (in partnership with sales)
