Short answer: Yes, you can. But the scaffold must meet your solar installer's exact specification, be erected by CISRS-certified operatives, and be ready on the confirmed install date.
Key Takeaways
- You can legally arrange your own scaffold — you are not required to use the installer's.
- The scaffold must meet your solar installer's specification.
- If the scaffold doesn't meet spec, your installer can refuse to start work.
- Savings are often smaller than expected — installers may have trade rates.
- Best case: combine with other at-height work (re-roof, chimney, gutters).
- Always share the installer's scaffold spec document with any scaffolder you approach.
When does arranging your own scaffolding make sense?
There are three scenarios where it genuinely saves money or effort:
- You're combining multiple at-height jobs. Roofer, solar installer and gutter team all working from the same scaffold. See combining solar and roof repair on one scaffold.
- You have an existing relationship with a local CISRS-certified scaffolder. Using them directly can be cheaper than the installer's sub-contract.
- You've obtained multiple quotes and the gap is significant. Worth discussing or sourcing independently.
What spec must the scaffold meet?
Your solar installer should provide a specification document. Typical MCS-aligned requirements include:
- CISRS-certified operatives — valid CISRS card copies required
- Scaffold sign-tagged before installation date
- Platform height less than 400mm from bottom edge of roof
- Platform extends at least 1.5m beyond outer edge of PV array, or double handrail edge protection at the array perimeter
- Ladder fixed to scaffold with a fall arrest gate at the top
- Toe boards on all outer edges
- If scaffold crosses public pavement — pavement licence in place
What are the risks of arranging independently?
| Risk | How likely | How to mitigate |
|---|---|---|
| Scaffold not ready on install day | Medium — coordination failure | Confirm erection date in writing with both parties. Build a 24-hour buffer. |
| Scaffold doesn't meet installer spec | Medium — if spec not shared | Share the installer's full spec document with the scaffolder before booking. |
| Installer refuses scaffold as unsafe | Low if CISRS-certified | Only use CISRS-certified companies. Request card copies before erection. |
| No cost saving vs installer's scaffolder | Common | Get three quotes. Factor in your coordination time as a cost. |
Frequently asked questions
Can I arrange my own scaffolding for solar panel installation?
Yes — you are legally allowed to arrange your own scaffold contractor for a solar installation. However, the scaffold must meet the exact specification required by your solar installer (CISRS-certified, correct platform height, edge protection, sign-tagged). Failure to meet the spec can result in the installer refusing to use it.
Is it cheaper to arrange your own scaffolding for solar panels?
It can be, but savings are often smaller than expected. Solar installers typically use scaffolding companies they have an ongoing trade relationship with and may receive trade rates. An independent quote from a local scaffolder might be similar in price once you factor in the coordination effort.
What spec must the scaffolding meet if I arrange it myself?
Your solar installer should give you a specification document. Naked Solar's published requirements include: CISRS-certified operatives, scaffold sign-tagged, platform less than 400mm below roof eaves, edge protection extending 1.5m beyond PV array edge, and a fixed ladder with a fall arrest gate. Request your installer's spec before booking.
What are the risks of arranging your own scaffolding for solar?
Coordination risk: if the scaffold is not ready on time, the install is delayed and may be charged as a cancellation. Spec risk: if the scaffold does not meet the installer's requirements, they will not start work. Liability risk: if something goes wrong, the chain of responsibility becomes less clear.
Can my solar installer refuse to use scaffolding I arranged myself?
Yes. If the scaffold does not meet their stated specification, the MCS-certified installer is within their rights to refuse to start the installation. They have a duty of care under Work at Height Regulations and cannot work from a scaffold that doesn't comply.
When does it genuinely make sense to arrange your own scaffolding?
If you already have an established relationship with a local CISRS-certified scaffolding company; if you are combining solar with other at-height work and the same scaffolder is doing all of it; or if you have compared quotes and the standalone scaffold is materially cheaper. In all cases, share the installer's spec with the scaffolding company before booking.
