London Cleantech Startup Metal Morph Raises 700,000 Pounds Pre-Seed, to Recover Chemicals From Wastewater
Updated: 6 days ago
A 700,000 pound pre-seed round is a small number against the billions moving through tokenisation headlines this week, but for founders trying to read how blended capital, grant funding stacked with angel and climate tech VC money, actually gets deployed at the earliest stage, this is a useful data point.
Metal Morph, is a London based infrastructure as a service cleantech startup founded by Moletsane Mophethe, and it has raised 700,000 pounds in pre-seed funding to develop an advanced chemical recovery platform that integrates directly into existing municipal and industrial wastewater treatment plants.
The round combined backing from climate tech venture capital funds and angel investors alongside a 100,000 pound grant from Ofwat, the economic regulator for the water sector in England and Wales.
The structure is a useful illustration of how early stage UK founders in capital intensive, infrastructure adjacent sectors are increasingly stacking non dilutive grant funding with equity rather than choosing one or the other. Ofwat grants are typically tied to demonstrable water sector outcomes rather than growth metrics, which gives founders like Mophethe a way to fund technical validation before asking equity investors to underwrite commercial traction.
For a sector like water infrastructure, where sales cycles into municipal and industrial customers can run to years, that blended structure matters more than the headline amount. It is also a reminder that founder access to capital, the structural story we are interested in, is not only about who gets a venture cheque. It is equally about which founders know a grant like Ofwat's exists, understand how to combine it with private capital, and can navigate two very different application processes at once.
Key Takeaways
Metal Morph raised 700,000 pounds pre-seed combining climate tech VC, angel money and a 100,000 pound Ofwat grant.
The startup's platform recovers chemicals from wastewater by integrating into existing municipal and industrial treatment infrastructure.
The blended grant and equity structure reflects a wider pattern in capital intensive early stage sectors, where non dilutive funding de-risks technical validation ahead of an equity round.
Founder access to structures like Ofwat grants, not just to VC networks, remains an underreported part of the capital access story.
How the round was put together
The £700,000 round was co-led by Sustainable Ventures and Green Angel Ventures, with Aqcelerator and Found Capital also taking part, according to Tech.eu. Metal Morph was founded in 2025, and Mophethe, who grew up in Lesotho, has linked the business to his early experience of water scarcity.
The Ofwat money is staged. The company received £100,000 up front, with a further £450,000 available as agreed milestones are met. That mirrors the wider Ofwat model. In the Water Discovery Challenge, run by Challenge Works with Arup and Isle Utilities, 20 finalists announced in July 2026 each receive £100,000 of seed funding, and up to 10 of them can win up to £550,000 each in April 2027.
The first technology targets aluminium and iron-based coagulants, the treatment chemicals that would otherwise be discharged to sewer, sent to landfill or spread on land. The company reports more than 50 live tests across three drinking water treatment plants, recovering up to 90% of spent chemicals at 95% purity and cutting coagulation-related operating costs by 26%. These are company-reported figures, not independent results.
What it means for UK founders
Milestone-based grant tranches change how a pre-seed budget is planned. Money that only arrives after a technical milestone cannot safely be counted as runway on day one, but once the milestone is hit it can extend runway without further dilution, which may reduce the size of the next equity round.
Utility relationships are the other asset. Metal Morph says it is working with six UK water utilities, including Anglian Water and Thames Water, which together represent 56% of the UK water market. In regulated infrastructure, named partners willing to host trials can carry as much weight with early investors as revenue.
Founders planning to combine public grants with SEIS or EIS backed equity may want to take professional advice, as grant terms and tax relief conditions can interact.

Frequently asked questions
How much did Metal Morph raise in its pre-seed round?
Metal Morph, a London based cleantech startup founded by Moletsane Mophethe, raised 700,000 pounds in pre-seed funding. The round combined climate tech venture capital, angel investors and a 100,000 pound grant from Ofwat.
What does Metal Morph's technology do?
Metal Morph is developing an advanced chemical recovery platform that recovers chemicals from wastewater. It integrates directly into existing municipal and industrial wastewater treatment plants on an infrastructure as a service basis.
What is Ofwat and why does an Ofwat grant matter for early stage founders?
Ofwat is the economic regulator for the water sector in England and Wales. Its grants are typically tied to demonstrable water sector outcomes rather than growth metrics, which can help founders fund technical validation before raising equity on commercial traction.
Why do UK cleantech startups combine grant funding with equity?
In capital intensive, infrastructure adjacent sectors such as water, sales cycles into municipal and industrial customers can run to years. Stacking non dilutive grant funding with equity helps de-risk technical validation ahead of an equity round.
