Decision-Makers.
The Problem.
Most commercial solar projects start with installer-led designs that cost nothing upfront and create problems later on.
Designs Vary Wildly
Different installers propose different system sizes, layouts and assumptions.
Without a clear brief, comparing options becomes guesswork.
Quotes Not Comparable
Prices often vary because scopes, equipment and outputs differ.
Cheapest rarely means best value over the long term.
Decisions Drag On
Too many conflicting proposals slow internal approvals.
Projects stall while teams try to make sense of it all.
Risk Sits With The Client
Without expert guidance, costly mistakes can be missed.
The client carries the risk of choosing wrong.
Tendera Approach.
Tendera works through three defined stages. Clients can exit after each stage, retaining full ownership of the work completed.
Feasibility & cost transparency
A paid upfront assessment that defines system size, grid strategy, battery approach, and true cost benchmarks.
Tender pack & tender management
A controlled procurement process using a standardised scope, enabling true like‑for‑like comparison.
Client‑side project delivery
End‑to‑end project management from mobilisation to commissioning and handover, using approved installers.

Not for Everyone - by Design.
Tendera works with owner‑led or privately controlled UK businesses that:
- Have a minimum project budget of £50,000 (ex VAT)
- Have a clear decision‑maker (owner, MD, FD, or Ops)
- Require installation within six months
- Want transparency, speed, and delivery certainty
- We do not provide speculative designs or compete on free proposals.
