Enviromena secures £825m bank-backed debt to deliver 1GW UK solar pipeline
This article covers Enviromena, a corporate energy developer, which has secured an £825m senior debt funding package to accelerate delivery of a 1GW solar pipeline across the UK. The financing, comprising a £525m committed tranche and a £300m uncommitted accordion, aims to move late-stage projects into construction and operation, supporting large-scale solar deployment and the UK’s energy transition.
Enviromena has signed an £825 million debt funding round, a senior portfolio financing package underwritten by a syndicate of banks that will accelerate delivery of a 1GW solar pipeline across the UK. The facility, with an initial £525 million commitment and a £300 million uncommitted accordion, is one of the largest solar financings in the UK this year and aims to move projects from late-stage development into construction and operation more quickly.
Why it matters
Large, project-level debt facilities are the lifeblood of utility-scale renewables. This transaction supplies immediate capital to push a substantial pipeline towards construction, supporting the UK’s wider objectives around energy security, decarbonisation and reducing long-term consumer costs. For the market, it is a signal that banks remain willing to back large solar portfolios, which could lower execution risk for future projects and encourage further private investment in onshore renewables.
Inside the product
The package is structured as a flexible platform financing: £525 million is committed now to enable rapid deployment, while a £300 million uncommitted accordion provides room to expand the facility as additional projects progress. That flexibility is designed to cover stages from late-stage development through construction to operational assets, making it easier to move projects across the completion gap that often separates consenting and grid connection from income-generating operation.
Perella Weinberg acted as exclusive financial adviser to Enviromena on the deal. Legal advisers included Travers Smith as borrower counsel and Eversheds Sutherland for the lenders.
Who are the investors?
The senior debt is underwritten by a syndicate of established banks: BBVA, Intesa Sanpaolo (IMI CIB), Lloyds, NatWest and Societe Generale. The arrangement combines committed capital with an uncommitted accordion to scale alongside the portfolio as projects advance.
Arjun Infrastructure Partners, which has supported Enviromena since 2017, also commented on the transaction and its strategic significance for the business.
In the announcement, Romain Py, Partner at Arjun Infrastructure Partners, said:

Founder perspective
In the announcement, Chris Marsh, CEO of Enviromena, said:
This is a landmark transaction for our business and demonstrates strong momentum in our growth strategy. With this support, we are accelerating the transition from development to delivery, building a gigawatt-scale solar platform to supply homes, businesses, and support the UK’s energy transition.
Importantly, this investment contributes directly to the UK’s net zero goals and the urgent need to scale low-carbon energy solutions. Rapid deployment of large-scale solar will be essential to meeting national targets, enhancing energy security, and reducing long-term costs for consumers.
The bigger picture
The deal sits within a wider rebound in large-scale project financing for renewables across Europe, where bank-led facilities and specialised infrastructure investors are increasingly active. For the UK, getting gigawatt-scale solar online faster helps diversify generation and eases pressure on electricity networks as demand patterns shift.
The transaction also underlines that established banks remain central to financing the energy transition, complementing equity from infrastructure funds and specialist investors. The success of this financing could encourage similar packages for other developers and support the delivery timetable required by UK net zero ambitions.
