Sanwa for companies

Are you an installer? This is everything we process for you.

CAEs, installation legalisations, energy certificates and works permits: a single platform that automates your company's paperwork so your team can focus on installing.

How we manage CAEs

A platform that processes, verifies and buys your CAEs for you.

Sanwa centralises the entire Energy Savings Certificate cycle: calculation, documentation, verification with an accredited body and connection with the Delegated Subject. Our engine automates every step so the case is ready in weeks, not quarters.

Once the CAE is issued, we buy it and settle it within the same week — and on every transaction you decide how much fee your company keeps.

    Purchase and settlement

    We buy the CAE and pay you

Legalisations17 autonomous communities

One legalisation, one single interface, every community.

We work across all 17 communities, prepare the standardised templates, file the documentation with the Industry authority and resolve any regional quirk. Depending on the community, we have registration receipts from just 3 days after filing.

On the platform you fill in a very simple form, the same for every community. No more needing an engineer to spend 45 minutes processing a legalisation: an administrative staff member with basic know-how gets it done with no trouble.
