Contractor Recharges & Service Credits 

​

To ensure consistent service delivery and minimise disruption to customers, Zuno reserves the right to apply financial recharges where a Supplier fails to meet the requirements of this Agreement. These recharges are intended to recover costs incurred by Zuno, including customer compensation payments, additional administration, and Job Gone Down (JGD) charges payable to installation teams. 

​

1. Scaffold No-Show 

​

Where a Supplier accepts a scaffold order and fails to attend on the agreed erection date without prior approval from Zuno, a recharge of £100 per occurrence will be applied. 

​

This recharge reflects the costs associated with: 

  • Customer compensation. 
  • Lost installation capacity. 
  • JGD charges payable to electricians and roofing teams. 
  • Additional administration and rescheduling. 

​

2. Late Erection 

​

Where scaffolding is not erected within the agreed Service Level Agreement (SLA), resulting in delays to the planned solar installation, Zuno reserves the right to recover all reasonable costs incurred, including: 

  • JGD charges. 
  • Customer compensation. 
  • Additional site visits. 
  • Administrative costs. 
  • ​

In addition, Zuno may apply a fixed service credit of £100 where the delay is solely attributable to the Supplier. 

​

3. Failure to Dismantle Within SLA 

​

Scaffolding must be dismantled within 2 working days of the confirmed completion of the solar installation unless otherwise agreed. 

Failure to meet this requirement may result in: 

  • Recovery of the cost of alternative scaffold contractors. 
  • Customer compensation costs. 
  • A fixed recharge of £50 per additional working day beyond the agreed dismantle date. 

​

4. Compliance & Quality Failures 

​

Where scaffolding is found to be non-compliant with TG20:21, Working at Height Regulations, manufacturer guidance, or Zuno's installation requirements, the Supplier may be liable for all associated costs. 

​

Examples include (but are not limited to): 

​

  • Missing scaffold tags or handover certificates. 
  • Missing ladder guards or access gates. 
  • Inadequate edge protection or toe boards. 
  • Unsafe access. 
  • Incorrect platform widths. 
  • Missing brick guards where required. 
  • Missing lifting systems where specified. 
  • Poor workmanship requiring remedial visits. 
  • Scaffold erected differently from the agreed scope. 

​

Where a compliance or quality issue prevents the installation from proceeding, Zuno may recover: 

  • All JGD charges. 
  • Additional scaffold attendance costs. 
  • Customer compensation. 
  • Internal administration costs. 

​

A fixed recharge of up to £100 per occurrence may also be applied depending on the severity of the non-compliance. 

​

5. Failure to Upload Documentation 

​

The Supplier is required to upload all required photographs, handover documentation and supporting information within the agreed timescales. 

​

Failure to provide: 

  • Pre-installation photographs. 
  • Scaffold photographs. 
  • Handover certificate. 
  • Scaffold tag. 
  • Ladder guard photographs. 
  • Post-dismantle photographs. 
  • ​

within 24 hours may result in a recharge of £25 per occurrence. 

​

6. Repeated Performance Issues 

​

Where a Supplier demonstrates repeated failures to meet Zuno's quality standards or SLA requirements, Zuno reserves the right to: 

  • Suspend allocation of new work. 
  • Remove the Supplier from the Approved Contractor Network. 
  • Recover all reasonable costs arising from repeated service failures. 
  • Terminate the agreement in accordance with the Installer Agreement. 

​

General 

​

All recharges will be reviewed on a case-by-case basis and will be supported by appropriate evidence, including photographs, installation records, customer correspondence, engineer reports and app data. 

​

Where multiple failures arise from a single event, Zuno reserves the right to recover the full cost incurred where these exceed the standard recharge values listed above.
