What Is UKRPS?

UKRPS is an independent UK organisation that works alongside MCS and FLEXI-ORB-accredited solar installers to validate solar performance projections using EPVS and RECC-approved methodology.

We are not a solar installer.
We do not sell panels or inverters.

Our role is simple:
to make sure the performance figures you are shown are realistic — and protected.

Key Benefits for Homeowners

When your installer partners with UKRPS, you benefit from:

✔ Independent Validation

Your system’s projected output and savings are reviewed using industry-recognised EPVS standards — not sales estimates.

✔ Conservative Projections

We apply a 10% safety buffer to projections so expectations are realistic, not optimistic.

✔ Financial Protection if Performance Falls Short

If your system produces more than 10% less than the validated benchmark, we compensate you for the shortfall.

✔ Long-Term Peace of Mind

Protection applies for up to 10 years, giving confidence well beyond installation day.(even if your installer seizes to trade)

✔ Clear, Transparent Limits

  • Up to £200 per year

  • Up to £2,000 total
    No hidden clauses, no vague promises.

✔ A Certified Protection Certificate

You receive a formal UKRPS Performance Protection Certificate confirming eligibility and protection terms.

✔ Added Confidence When Choosing an Installer

UKRPS is only available through approved, MCS-accredited partner installers — a further quality signal.

How It Works

Step 1: Validation

Before installation, your installer submits system details for independent validation using EPVS methodology.

Step 2: Protected Benchmark

We reduce the projected output and savings by 10%.
This adjusted figure becomes your protected performance benchmark.

Step 3: Ongoing Protection

If annual performance falls below this benchmark, you may claim compensation under the UKRPS protection terms.

What Protection Do You Receive?

  • Up to £200 per year if underperformance occurs

  • Up to 10 years of protection

  • £2,000 maximum total compensation

  • Claims assessed annually based on verified generation data

Protection applies only where eligibility conditions are met.

Important Transparency

UKRPS believes in clarity.

UKRPS Is:

✔ Independent
✔ Performance-based
✔ Contractual protection

UKRPS Is NOT:

✘ Insurance
✘ A manufacturer warranty
✘ A replacement for installer workmanship guarantees

Your installer remains responsible for installation quality and system setup. UKRPS protects performance expectations, not physical components.

Frequently Asked Questions

Is this an insurance policy?

No. UKRPS is a contractual performance protection scheme, not an insurance product.

Is this the same as an installer warranty?

No. Installer warranties cover workmanship and faults.
UKRPS covers underperformance against validated projections.

How do you decide if a system has underperformed?

We compare verified annual generation data against the validated, buffered EPVS RECC benchmarks.

What data do you use to assess performance?

Generation data from your inverter, monitoring platform, or meter readings.

What happens if my system produces more than expected?

That’s great news — no action is required. UKRPS only applies if performance falls short.

Are there any exclusions?

Yes. Protection does not apply where underperformance is caused by:

  • New shading (trees, buildings, extensions)

  • Equipment tampering or poor maintenance

  • Unrepaired faults or inverter failures

  • Changes to the system after installation

  • Extreme weather events or force majeure

  • Failure to provide accurate generation data

Full terms apply.

Can I transfer the protection if I sell my home?

Protection is not automatically transferable. Any transfer must be approved by UKRPS in writing.

Do I need to do anything each year?

You must provide access to annual generation data and ensure the system is reasonably maintained.

How do I make a claim?

Claims are submitted annually within the stated claim period.
If approved, compensation is paid directly to you.

Does every installer offer UKRPS?

No. UKRPS is only available through approved partner installers who meet our requirements.

Choosing Solar With Confidence

Solar projections should be honest.
Savings should be realistic.
And homeowners shouldn’t carry all the risk.

UKRPS exists to bring clarity, accountability, and confidence to UK solar installations.

Ask Your Installer About UKRPS

When comparing quotes, ask:

“Is this system independently validated and protected by UKRPS?”

If the answer is yes, you’re choosing one of the most transparent solar options available in the UK today.
