Energy bills are biting hard, and most businesses know the pressure isn’t easing any time soon. Add to that the government’s net zero commitments, and the message to developers and organisations is clear: the future has to be lower carbon. Solar PV and battery storage are often the first technologies people turn to. But here’s the catch – no matter how good the technology, if it isn’t installed to the right standards, the project can quickly become more of a liability than an asset.
The Smart Export Guarantee (SEG), introduced by Ofgem in 2020, gives businesses a chance to earn money from the renewable electricity they export back to the grid. It sounds straightforward, but in reality it comes with strict requirements. Systems must be designed, installed, and certified correctly. Miss one step, and developers risk missing out on SEG income entirely. That’s why compliance is not just a “nice-to-have” – it’s the key that unlocks value.
Why Solar PV and Battery Storage Matter Now
For most organisations, electricity is one of the biggest running costs. It’s unpredictable too – prices rise with little warning. Solar PV helps offset that demand, but without a way to store excess power, businesses often end up selling energy back to the grid at low SEG rates while buying it back later at a higher price. Batteries change the game. They allow you to keep daytime generation on site and use it when demand – and prices – peak. For developers planning warehouses, schools, or healthcare facilities, this makes the difference between a project that simply ticks the sustainability box and one that delivers genuine operational savings.
Understanding the SEG Scheme
The SEG requires licensed electricity suppliers to pay small-scale generators for every unit of renewable electricity they export. For businesses, this creates an extra income stream. But, and it’s a big but, SEG payments only apply if the installation meets MCS standards and follows ENA G98/G99 grid connection rules. Skip compliance, and you lose eligibility altogether. Developers can find full details on Ofgem’s own guidance page here: Ofgem – Smart Export Guarantee.
The Compliance Framework You Can’t Ignore
- IET Wiring Regulations (BS 7671:2024) – the backbone of safe electrical design and installation.
- MCS MIS standards – the certification route for solar and battery systems, and the gateway to SEG eligibility.
- ENA G98/G99 – the grid connection rules that ensure distributed generation integrates safely.
- Electricity at Work Regulations 1989 – requiring systems that prevent danger to people and property.
- CDM Regulations 2015 – setting duties for developers and contractors during construction.
The truth is, compliance does more than satisfy regulators. It keeps people safe, ensures insurance cover, and avoids expensive rework down the line.
The Benefits of Doing the Job Properly
Choosing a compliance-first contractor doesn’t just tick boxes. It creates long-term value. Businesses gain SEG income that would otherwise be lost. They face fewer operational risks because systems are tested and signed off correctly. Insurers are far more likely to provide cover. And importantly, developers avoid reputational damage by showing stakeholders that projects are both sustainable and safe.
Pitfalls Developers Need to Watch For
Unfortunately, there are still contractors in the market who cut corners. Common warning signs include exaggerated savings claims, a lack of DNO approval, equipment that isn’t MCS listed, or vague promises about “eco-friendly” results without evidence. Some even hand over projects without the right documentation, leaving clients unable to claim SEG payments. For developers, spotting these pitfalls early can prevent costly mistakes later.
What to Expect from a Trusted Solar Partner
So what should developers demand? At minimum: NICEIC Approved Contractor status, MCS certification for solar PV and storage, a strong record of ENA G99 submissions, and full transparency on documentation. Ask for commissioning certificates. Ask about similar projects they’ve delivered. Ask how they calculate sustainability benefits. The right partner won’t hesitate to provide evidence.
At Ranger Electrical Services (North West) Ltd, all of this is standard. We are accredited by NICEIC, MCS, ECA, and CHAS, and our renewable installations are delivered with compliance front and centre. See more about our expertise on our Renewables page.
Real-World Examples
Our portfolio shows how compliance translates into real benefits. For warehouses, we’ve delivered solar PV integrated with battery storage to cut demand charges and protect operations. Councils we work with now generate clean power across public buildings, supported by SEG income that feeds back into local budgets. In healthcare and education, we’ve designed renewable systems with resilience built in, ensuring critical services can continue even during power interruptions. You can explore examples on our Projects page.
A Developer’s Quick Checklist
Before moving forward with any solar and storage installation, ask these five questions:
- Are you MCS-certified for both solar and storage?
- Will you handle the G99 process with the DNO?
- Can you show me recent commissioning certificates?
- How do you calculate SEG payments and savings, and can I see the assumptions?
- What large-scale projects have you delivered that compare with mine?
If the answers aren’t clear or backed up with evidence, proceed with caution.
