How Invictus Works
One connected process — from your first enquiry to your installer arriving on site.
Contact TEC about a repair, installation, battery upgrade, EPS or backup power addition, replacement or other renewable energy project.
Our team reviews the requirements, identifies missing information and prepares the opportunity for suitable registered installers.
Registered installers review the available job and technical information, then submit their proposed rates and pricing.
Compare the offers side by side and select the proposal that best suits your needs.
Following acceptance, you and your installer coordinate availability and make arrangements directly.
We can assist with technical questions, commissioning, DNO documentation and issues arising during the project where appropriate.
For Customers
Get in touch about your project and our team will review it with you — resolving anything we can remotely first. If physical work or new equipment is needed, we prepare the opportunity and put it in front of suitable registered installers, who each submit their own proposal.
You compare the offers side by side and choose the installer you wish to proceed with. Once you accept, you and your installer coordinate the work directly.
The more we know upfront, the better installers can quote. Don't worry about getting it perfect — our team will follow up on anything missing.
For Installers
Invictus gives approved installers access to repair, upgrade and installation opportunities — with the information you need before you commit, and the freedom to price your own work rather than being assigned jobs at predetermined rates.
Every installer is reviewed and approved by our team before being granted access. We approve access personally — no instant, unvetted sign-ups.
Enquire to Join InvictusInstaller Review
We aim to build a network of capable, reliable renewable energy professionals through an installer review and approval process — looking at experience and standards before granting access to the platform.
Approval means an installer has passed our review process — it doesn't guarantee any particular outcome on your job, and you always retain the choice of which installer to appoint.
We gather the details, equipment information and site context before jobs are released, so installers quote on facts rather than guesswork.
More Than a Job Board
We're renewable energy specialists first — our team is available at every stage of your project, including DNO application and notification assistance where appropriate. (TEC does not assume the installer's legal or regulatory responsibilities.)
Commercial Transparency
We facilitate the introduction, job preparation and coordination. Where we have a commercial involvement in a project, our role is made clear — we're not an escrow service or a dispute-resolution body.
Tell us what you need — we'll prepare the opportunity and bring the offers to you.
