Specialist Financial & Management Consultancy for the Public Sector
Senior financial expertise for the decisions the public sector can't get wrong.
Nonsuch Finance is a specialist financial and management consultancy working exclusively with local government, central government, the NHS and public bodies. We help finance and executive leaders bring clarity to complex financial and organisational challenges — from reorganisation and reform to efficiency, transformation and long-term sustainability — with senior-level expertise applied directly, not filtered through layers of delivery teams.
Founded by a former Chief Finance Officer of the Greater London Authority, with 30+ years of senior public sector finance leadership.
Credibility
Senior financial leadership. Specialist public sector knowledge. Direct, practical advice.
Nonsuch Finance works with organisations across local government, central government departments, NHS trusts and public bodies — bringing senior public finance leadership experience from the Greater London Authority, the Cabinet Office, the Home Office, local government and the NHS directly to every engagement.
Why we exist
A specialist alternative to the traditional consultancy model
Public sector organisations are being asked to make increasingly difficult financial decisions — often on compressed timelines, under public and political scrutiny, and with less internal capacity than the scale of the challenge demands. Local Government Reorganisation, SEND and High Needs Block pressures, transformation programmes and long-term financial sustainability all require the kind of senior, specialist financial judgement that is expensive to hold permanently in-house and difficult to access quickly through a large consultancy structure.
Nonsuch Finance was founded to close that gap. We provide the calibre of financial thinking associated with the largest professional services firms, delivered directly by senior practitioners who have held public sector finance leadership roles themselves — without the scale, cost base or delivery hierarchy of a major consultancy. Every engagement is led by senior expertise from first conversation to final recommendation.
We work across two connected disciplines: financial consultancy — strategy, planning, management, business case development, climate budgeting and green finance — and management consultancy — efficiency review and corporate services transformation. Increasingly, our work concentrates on the moments where these two disciplines meet: Local Government Reorganisation and SEND/High Needs Block reform, where financial and operational decisions cannot sensibly be separated.
The work
The challenges we help solve
- 01 Financial Strategy Helping leadership teams set a coherent financial direction, establish priorities under constraint, and build a strategy that can withstand political, regulatory and public scrutiny.
- 02 Financial Planning & Forecasting Strengthening budget setting, medium-term financial planning and resource allocation, so financial plans reflect realistic demand and cost assumptions rather than historic trend alone.
- 03 Organisational Efficiency Identifying genuine, defensible opportunities to reduce cost and improve resource use — without compromising statutory service delivery or outcomes.
- 04 Transformation & Reorganisation Providing the financial rigour that large-scale change — including Local Government Reorganisation and corporate services redesign — depends on, from opening budgets through to a credible medium-term plan.
- 05 Business Case Development Strengthening the financial evidence, benefits, costs and risk case behind significant investment and transformation decisions, so they hold up to governance and external scrutiny.
- 06 Climate Budgeting & Green Finance Helping organisations integrate climate priorities and sustainable financing approaches into mainstream financial planning, rather than treating them as a parallel workstream.

Our services
Specialist expertise
Featured specialist expertise
We work across two connected disciplines: financial consultancy — strategy, planning, management, business case development, climate budgeting and green finance — and management consultancy — efficiency review and corporate services transformation. Increasingly, our work concentrates on the moments where these two disciplines meet: Local Government Reorganisation and SEND/High Needs Block reform, where financial and operational decisions cannot sensibly be separated.
01
Local Government Reorganisation
Reorganisation compresses years of normal financial planning into months, under public scrutiny and with limited room for error. We provide senior-level financial advisory across the full transition — from financial assessment and budget modelling to business case development and implementation support.
02
SEND & High Needs Block Reform
Rising EHCP demand and sustained High Needs Block pressure are driving DSG deficits across the country. We provide specialist financial advisory for SEND transformation, DSG deficit recovery planning, and Safety Valve or Delivering Better Value arrangements.
03
Efficiency & Corporate Services Transformation
Structured, independent efficiency reviews and corporate services redesign that identify genuine savings without compromising statutory delivery.
04
Climate Budgeting & Green Finance
Practical integration of climate and sustainability priorities into core financial planning and investment decisions.
Public sector

- NHS & Health Organisations Specialist financial and management support for NHS trusts and health system partners, drawing on direct NHS finance experience.

Leadership
Enver Enver
Founder & Managing Director
Enver Enver founded Nonsuch Finance following a career as Chief Finance Officer at the Greater London Authority, bringing over 30 years of senior public sector finance leadership across the GLA, the Cabinet Office, the Home Office, local government (county, unitary and district) and NHS trusts.
Enver has recently worked in partnership with Langbrook Finance to provide senior financial advisory services on behalf of the Department for Education to local authorities and Integrated Care Boards developing and submitting their SEND Reform plans — direct, current experience of the exact pressures many public sector finance teams are navigating today.
That experience shapes how Nonsuch Finance works: senior-level financial judgement applied directly to your organisation's position, not filtered through junior delivery teams.
