New RE:FIT 5 Framework Strengthens Role of Independent Measurement & Verification (M&V)
The launch of the new RE:FIT 5 Framework marks an exciting next step for public sector energy efficiency and decarbonisation in London and beyond. The programme - recently announced by the Mayor of London - continues to support public bodies in delivering energy and carbon saving projects at scale, with a renewed focus on performance, transparency, and guaranteed outcomes. Read the announcement here.
Supporting Cost Savings, Carbon Reduction & Risk Management
RE:FIT 5 continues to offer a robust, procurement‑ready route for public sector organisations to implement energy efficiency, renewable energy and low‑carbon upgrades. By embedding energy performance contracting principles, it helps organisations reduce energy costs and carbon emissions while managing delivery risks through savings guarantees.
At the heart of these guarantees is Measurement & Verification (M&V) - the process that quantifies real‑world performance and confirms whether promised energy and carbon savings are actually achieved.
A Stronger Role for Independent M&V
One of the most welcome upgrades in RE:FIT 5 is the strengthened requirement for independent Measurement & Verification.
This is a significant step forward for the sector. Independent M&V:
Builds trust in reported savings by ensuring findings are impartial and transparent.
Strengthens credibility for both clients and service providers, enabling long‑term, performance‑driven partnerships.
Aligns the framework with international best practice, including the IPMVP (International Performance Measurement & Verification Protocol), which requires third‑party verification when guarantees are involved.
Reduces risk by ensuring that savings guarantees are supported by robust, unbiased technical evidence.
As public sector organisations face increasing pressure to deliver proven energy and carbon reductions - supported by defensible data - this shift toward independent oversight represents a major enhancement to the RE:FIT framework.
EEVS: The UK’s Leading Provider of Independent M&V for RE:FIT
EEVS has been a key part of the RE:FIT journey for over 10 years, supporting public sector organisations and their service providers with independent M&V and third‑party technical review across projects for Local Authorities, Central Government, the NHS and Education.

Our long‑standing experience means we understand the nuances of energy performance contracting, the risks, the data requirements, and the practical steps needed to ensure that savings can be robustly reported and guarantees enforced.
Considering a RE:FIT 5 Project? Embed M&V from the start.
Successful M&V doesn’t begin at project completion - it must be designed into your project from the very start. Early M&V planning is essential to:
Select the right savings measurement approach
Ensure good quality data
Agree robust baselines
Make sure guarantees are measurable and enforceable
Avoid disputes later on
