The accountant who got tired of solar roulette.
Worpra was started by Gordon Wilson, an Aylesbury-based Chartered Accountant, after seeing the same pattern too often: three solar quotes, three wildly different numbers, and nobody showing the working.

Why Worpra exists
Solar should not feel like quote roulette.
The model is simple: Worpra designs the system, holds the customer relationship, vets and inspects the installation team, and connects compatible batteries so they can keep earning after the install.
That means the buying process starts with the maths, not a commission visit. If the roof, shading or usage make the payback poor, we say so.
Standards
The promise is careful competence.
Installer checks
Worpra checks certification, insurance, references, finances and past work before jobs are offered.
