Commercially: “we want to save money”

This is an extract from a BBC article b y Dave Harvey (published 18th May):

Rise in solar panel sales as people ‘want to save money’

“It’s all about saving money now, not just sustainability.”

Those are the words of the founder of a solar power firm who sums up the shift in the industry neatly. Ben Harrison’s Gloucestershire company has installed 65% more solar panels for businesses since the Iran war started, and energy bills soared.

Across the UK, the total amount of solar power installed has risen 11% compared to last year, according to government figures. For companies, the maths is simple.

In Somerset, the makers of the Henry vacuum cleaner have just spent £1.5m on new solar panels at their Chard factory. The financial director said he will get his money back “in less than four years”.

On a sunny day, this field of solar panels will power the whole factory behind it making vacuum cleaners in Chard, Somerset.

Fly low over a typical industrial estate and you’ll see plenty of solar panels on factory rooftops. But at the huge Numatic plant in Chard, they have gone to a new level.

They have just filled a whole field behind the factory.

There are 1,200 people working here, making Henry, the famous little red vacuum cleaner, and his pink friend Henrietta.

They make everything except the motors on site, from scratch. Moulding their own plastic and automated robotic production sucks power like, well a vacuum cleaner.

“Electricity is hugely expensive,” says Steve Whitlock, the firm’s financial director.

He is proudly showing me the brand new field of solar panels, 2,672 in all.

Until recently, it would be sustainability managers promoting this kind of work. But today, a solar installation costing £1.5m is “a major investment, like any other”, according to Whitlock.

“We need electricity to manufacture our products, and with the price going up and up, this solar field has given us a step change to generate our own electricity, and not rely on the market,” he added.

On sunny days, the new system will power the whole plant. Across the year, they project it will average about a quarter.

But further investments in high-tech inverters and batteries will take them to about half their total energy needs.

Within four years, Whitlock calculates the solar system will have paid for itself.

And next time a global conflict pushes up the price of electricity, this factory will be more protected.

The Somerset solar field is unusually big, but it’s not unique.

Since the Russian invasion of Ukraine first caused energy prices to soar, many firms have looked at solar power as an investment, not just a green initiative.

Now the war in Iran has pushed energy bills up again, and companies worry about what else might happen in the future.

Government figures revealed a big increase in March 2026, with 27,000 new solar installations in total. That is the highest since 2012, and pushed the total number of solar systems to over two million.

Official statistics do not separate solar power on commercial buildings from residential installations. But because companies use power in the daytime, while the sun is out, they stand to save a lot more than domestic customers, whose main use is in the morning and evening.

Chris Hewett, CEO of the trade body Solar Energy UK, said the south-west had seen the biggest increase in the country in solar panels installed by companies.

He believes solar power is the “quickest and most effective” way for business to cut energy bills.

The solar panels on this wine warehouse in Gloucester will provide 42% of its power

High on a warehouse rooftop in Gloucester, Ben Harrison spells it out starkly for me.

He started Mypower, his solar installation firm, 15 years ago.

“In the early days it was mainly about sustainability,” he said.

“Now it’s all about money. Customers are all about controlling their long-term electricity costs, as prices of energy have gone up.”

Over the last three months, his firm has installed 1,783 solar panels per month, 65% more than the average over the rest of the year.

Beneath him, the wine warehouse buzzes with activity.

Forklifts whirr along, pallets laden with red, white and fizz.

Automated conveyor belts shuttle boxes of wine along to a massive pallet wrapper, like a giant cling film dispenser twirling the pallets around ready for shipment.

It all uses a huge amount of electricity. The day I visited it was cloudy, but the 1,710 panels were still powering the whole site, and selling some to the national grid on top.

Loreta Landray, of Laithwaite’s Wine, said it was a “fantastic day” when the panels were switched on

Loreta Landray, health and safety manager at Laithwaite’s Wine, who run the warehouse, said it was “fabulous” when the panels were switched on.

“The cost increase in energy has been phenomenal for the last five years, and it will help massively for the business going forward, when it comes to paying for electricity,” she added.

While many families struggle to keep up with rising energy bills, fueled by the war in Iran, companies are now deciding to spend big money to keep their future bills under control.

A Builder’s Guide to Reliable Project Partnerships

Choosing the right Electrical Contractor – Your 7 Point Guide

In today’s construction environment, small and medium-sized building contractors are under increasing pressure to deliver projects on time, on budget, and to a consistently high standard.

Successful projects are rarely delivered by individual trades working alone. They are achieved through strong collaboration between experienced professionals who understand the importance of teamwork, accountability, and shared project success.

One of the most important relationships on any project is between the builder and the electrical contractor. When that relationship works well, projects run smoother, communication improves, delays are reduced, and clients are happier.

The challenge for many builders is identifying which electrical contractor is the right fit for their business and their projects. Price will always matter, but the cheapest quote rarely delivers the best long-term value. Builders need electrical contractors who can integrate into the wider construction team, solve problems quickly, and help protect the project timeline.

Why the right Electrical Contractor matters

Electrical works now play a central role in almost every construction project. From domestic housing developments to commercial refurbishments, electrical installations are more advanced than ever, often involving:

  • Smart home technologies
  • Energy-efficient lighting systems
  • EV charging infrastructure
  • Fire and security systems
  • Data and communication networks
  • Renewable energy integration

A reliable electrical contractor does more than install cables and fittings. They become part of the project delivery team.

An experienced contractor can help builders by:

  • Identifying design issues early
  • Coordinating effectively with other trades
  • Maintaining programme schedules
  • Managing compliance and certification
  • Reducing costly rework
  • Supporting health and safety requirements
  • Presenting professionally to clients and site managers

What builders should look for

1. Proven Industry Experience

Experience remains one of the strongest indicators of reliability. Builders should look for electrical contractors with a track record in projects similar to their own.

A contractor experienced in residential new builds may not necessarily be suitable for commercial fit-outs or industrial works. Ask potential partners for examples of completed projects, references, and case studies.

Key questions include:

  • Have they worked on projects of similar size and scope?
  • Can they demonstrate repeat business with builders?
  • Do they understand modern building methods and regulations?
  • Are they familiar with fast-paced site environments?

Experienced contractors typically anticipate problems before they become delays.

2. Strong Communication and Collaboration

Construction projects succeed through coordination. Electrical contractors must be able to work collaboratively with site managers, plumbers, HVAC engineers, joiners, and other trades.

Poor communication often causes:

  • Programme clashes
  • Missed deadlines
  • Incorrect installations
  • Material delays
  • Additional labour costs

Builders should seek contractors who:

  • Attend coordination meetings
  • Respond quickly to queries
  • Provide clear progress updates
  • Raise issues early
  • Work proactively rather than reactively

The best electrical contractors understand they are part of a larger delivery team, not operating independently.

3. Reliability and Resource Capability

One of the biggest risks for builders is appointing contractors who cannot resource the project properly.

A reliable electrical contractor should have:

  • Adequate qualified labour
  • Supervisory support
  • Consistent supply chain relationships
  • Contingency plans for labour shortages
  • The ability to scale with project demands

Builders should assess whether the contractor can genuinely support multiple phases of work without compromising quality or deadlines.

Consistency is critical. Turning up when promised and maintaining labour levels on site builds trust quickly.

4. Accreditation and Compliance

Electrical compliance is non-negotiable. Builders should only work with properly accredited contractors who understand current regulations and certification requirements.

Important considerations include:

  • NICEIC or equivalent accreditation
  • Up-to-date public liability insurance
  • Health and safety policies
  • Qualified electricians and supervisors
  • Testing and certification capability
  • Compliance with current wiring regulations

Failure in compliance can create major legal and financial consequences for builders and developers alike.

5. Commercial Awareness

The best electrical contractors understand construction pressures beyond their own trade.

They recognise the importance of:

  • Budget control
  • Programme deadlines
  • Minimising variations
  • Protecting builder-client relationships
  • Delivering snag-free handovers

Commercially aware contractors help builders avoid unnecessary costs and disputes.

Rather than simply identifying problems, strong contractors bring solutions.

6. Quality of Workmanship

Quality electrical installation affects both safety and reputation. Poor workmanship often becomes visible late in the project, causing delays, failed inspections, or expensive remedial works.

Builders should inspect previous work where possible and look for:

  • Neat containment and cable management
  • Accurate first-fix installation
  • Professional finishing standards
  • Proper labelling and documentation
  • Organised testing procedures

Attention to detail often reflects the overall professionalism of the contractor.

7. Adaptability and Problem Solving

Construction rarely goes exactly to plan. Drawings change, client requirements evolve, and site conditions create unexpected challenges.

Builders benefit greatly from electrical contractors who remain flexible and solutions-focused.

A good contractor will:

  • Adapt to programme changes
  • Coordinate revised works efficiently
  • Suggest practical alternatives
  • Minimise disruption to other trades
  • Maintain a positive site attitude

Problem-solving ability is often what separates average subcontractors from long-term project partners.

Building Long-Term Relationships

Many successful builders prefer to establish long-term working relationships with trusted electrical contractors rather than sourcing new subcontractors for every project.

Long-term partnerships create:

  • Better communication
  • Improved efficiency
  • Familiarity with working methods
  • Greater trust on commercial matters
  • Faster mobilisation on future projects

Electrical contractors who consistently perform well become valuable assets to a builder’s business.

The Value Beyond Price

While competitive pricing is important, builders should avoid selecting electrical contractors based solely on the lowest quotation.

Low-cost pricing can sometimes result in:

  • Labour shortages
  • Inferior materials
  • Delays
  • Increased variations
  • Reduced supervision
  • Lower installation quality

The true value of a professional electrical contractor is measured in reliability, collaboration, quality, and project support.

A dependable contractor helps builders protect both profitability and reputation.

Final Thoughts

In a competitive construction industry, builders need subcontractors who contribute positively to project delivery, not add unnecessary risk.

The best electrical contractors are those who combine technical expertise with professionalism, communication, reliability, and commercial understanding.

For small and medium-sized builders, choosing the right electrical partner can significantly improve project outcomes, strengthen client relationships, and support long-term business growth.

Successful projects are rarely delivered by individual trades working alone. They are achieved through strong collaboration between experienced professionals who understand the importance of teamwork, accountability, and shared project success.

Plug-and-Play Renewables

Balcony Clip-on … Solor solution, or disaster waiting to happen?

The idea that plug-and-play balcony solar panels could be rolled out as a quick response to energy insecurity might sound pragmatic on the surface, but from a safety, regulatory, and technical standpoint, it raises serious concerns that deserve scrutiny.

As a professional electrician … it makes my fuses buzz!

The Hidden Risks of DIY Balcony Solar Installations

In the wake of global energy instability, worsened by tensions around the Strait of Hormuz, the UK Government has moved to approve so-called “clip-on” balcony photovoltaic (PV) systems. Marketed as simple, off-the-shelf solutions that people can install themselves, these systems promise instant access to renewable energy: clip them onto a balcony, plug them in, and put the kettle on.

Really?!?

This ‘apparent’ simplicity masks a number of critical safety and compliance issues.

A Regulatory Contradiction

For years, the UK has enforced stringent requirements for electrical installations. Qualified electricians, often accredited through professional bodies like the Institution of Engineering and Technology (whose members abbreviate to MIET), must demonstrate competence, undergo rigorous training, and adhere to national standards such as BS 7671 (the IET Wiring Regulations).

These standards are not optional. They exist to prevent electrical fires, ensure safe operation, and protect both property and life. Oversight from bodies like the Health and Safety Executive (HSE) reinforces the expectation that electrical work, particularly generation equipment connected to domestic circuits, must be carried out safely and competently.

Against this backdrop, allowing untrained individuals to install grid-connected generation devices represents a stark inconsistency in policy.

It’s frankly bonkers!!!

Electrical Safety Concerns

1. Backfeeding and Circuit Integrity

Plug-in PV systems typically connect directly into a domestic socket. This introduces the risk of “backfeeding,” where electricity flows in unintended directions through the circuit. Standard household wiring in the UK is not designed for distributed generation at socket level, and protective devices may not operate correctly under these conditions.

2. Overloading and Thermal Risk

Ring circuits and radial circuits are designed with specific load assumptions. Introducing generation at arbitrary points can lead to uneven load distribution, potentially causing overheating of conductors, loose connections, or socket outlets. These are conditions that significantly increase fire risk.

3. Lack of Proper Isolation

Professionally installed PV systems include dedicated isolation switches, allowing safe disconnection for maintenance or in emergencies. DIY plug-in systems often lack robust isolation mechanisms, leaving occupants, and emergency responders, at risk.

4. Earthing and Fault Protection

Correct earthing and bonding are fundamental to electrical safety. Without proper verification, a DIY installation may fail to meet fault protection requirements, increasing the risk of electric shock.

Non-Compliance with National Standards

The UK’s electrical infrastructure operates under clearly defined regulations. BS 7671 specifies how generation equipment must be connected, including requirements for:

  • Dedicated circuits
  • Appropriate protective devices
  • Certification and inspection

DIY balcony PV systems, by their nature, bypass many of these requirements. Simply plugging a generator into a micro-invertor or socket does not align with the principles of safe design outlined in national standards. In effect, these installations risk operating outside the regulatory framework that governs all other forms of electrical work.

Structural and Mechanical Risks

Beyond electrical issues, there are physical safety considerations:

  • Wind loading on balcony-mounted panels can lead to detachment if not properly secured.
  • Falling panels pose a hazard to people below.
  • Improper mounting could damage building structures or breach leasehold agreements.

Hey, Mr Starmer, these are serious issues.

The Skills Gap Problem

The notion that complex electrical systems can be safely installed by individuals with little or no training is optimistic at best, and dangerous at worst.

Electricians spend years developing the expertise required to assess load calculations, verify circuit integrity, and ensure compliance. Reducing this to a “plug-and-play” activity undermines both the profession and the safety framework it supports.

How many MPs does it take to change a light bulb? None – they’d all call a qualified electrician.

A Better Path Forward

The intent behind promoting small-scale solar adoption is understandable. However, a safer and more coherent approach would include:

  • Mandating installation or inspection by qualified electricians
  • Requiring compliance certification for all grid-connected systems
  • Providing clear public guidance on risks and limitations
  • Encouraging innovation within the framework of existing safety standards

Conclusion

Balcony-mounted PV systems may offer a convenient entry point into renewable energy, but convenience cannot come at the expense of safety and compliance. The current approach risks creating a two-tier system – one governed by rigorous standards, and another effectively exempt from them.

If the UK is serious about renewable energy (and we should be), it must ensure that new technologies, no matter how small or accessible, are held to the same principles that underpin the entire electrical industry.

Anything less is not innovation; it is a serious and potentially disastrous compromise on safety.

Your Roof is an Untapped Asset

Turning Space into Energy and Revenue

For many owners of commercial property and larger residential buildings across England, the roof has long been treated as a passive necessity, something that keeps the rain out and little more. But in today’s energy landscape, that same roof space represents one of the most underutilised financial and environmental assets available.

With rising electricity prices, ongoing grid uncertainty, and increasing pressure to decarbonise, solar photovoltaic (PV) systems are no longer a “green-thinking extra”, they’re a strategic investment.

And crucially, the economics are far more compelling than many property owners realise. For commercial buildings and high-end homes alike, unused space could be actively generating energy, reducing operational costs, and creating long-term financial value.

With the cutting edge solar technology we advise on and instal, what was once passive infrastructure can now deliver measurable returns, often saving tens, if not hundreds, of thousands of pounds over time.

The conversation is shifting from “Can we install solar?” to “Why wouldn’t we maximise the asset we already own?”

The hidden value sitting above your head

A typical commercial or large residential property roof, offers significant usable surface area. Even allowing for access, shading, and plant equipment, most roofs can accommodate substantial solar capacity.

As a rule of thumb:

  • For early feasibility / proposals in the South of the UK:
  • South‑facing: 1,050 kWh/kWp/year
  • East–West: 950 kWh/kWp/year (south facing would require more space between rear of module and front of next module due to shading from module in front)
  • Very conservative assumption: 1,000 kWh/kWp/year

Example: Medium Commercial Building

  • Roof space available: 500 m²
  • Usable for solar: ~400 m²
  • System size: ~~50 kWp (That would typically be ~100 × 500 W modules.)
  • Annual generation: ~@950kwh per m²: ~47,500 kWh (47.5 MWh)

That’s not just energy, it’s a hedge against future price volatility and a direct reduction in operating costs.

Turning generation into financial return

The real value of solar is self-generated power, displacing the uncertainties and high costs of grid electricity.

Current commercial electricity costs (Typical Range)

  • Grid electricity: £0.20–£0.35 per kWh (often higher under certain contracts)
  • Solar generation cost (levelised): ~£0.05–£0.10 per kWh

This creates an immediate margin of savings.

Example Savings

Using the 70 kWp system above:

  • Annual generation: 65,000 kWh
  • Self-consumption: 70% → 45,500 kWh used onsite
  • Grid price: £0.25/kWh

Annual savings

  • 45,500 × £0.25 = £11,375 per year

Excess energy (exported to the grid) can still generate income, typically:

  • Export rates: £0.05–£0.15 per kWh
  • Exported energy (~19,500 kWh): ~£1,000–£2,500 per year

Total annual benefit: ~£12,500–£14,000

Installation costs and payback – it’s shorter than expected

One of the most persistent myths is that solar takes decades to pay back. That may have been true in the past, but certainly not today.

Typical installed costs (Commercial Scale)

  • £700–£1,000 per kWp (depending on scale and complexity)

For a 70 kWp system:

  • Capital cost: ~£50,000–£70,000

Payback Period

With annual returns of ~£13,000:

  • Simple payback: ~4–6 years

Given system lifespans of 25–30 years, that leaves potentially two decades of low-cost electricity after payback.

Larger Roofs, Stronger Returns

The economics improve further at scale.

Example: Large Industrial Unit

  • Roof space: 2,000 m²
  • System size: ~300 kWp
  • Annual generation: ~270,000 kWh

Financials:

  • Installation: ~£210,000–£270,000
  • Annual savings & revenue: ~£50,000–£70,000
  • Payback: ~3.5–5 years

Larger systems benefit from:

  • Lower cost per kWp
  • Higher on-site consumption (especially for energy-intensive operations)
  • Greater protection against future price increases

Beyond the Numbers: Strategic Advantages

While the financial case alone is compelling, solar also delivers broader value:

  • Energy price stability: Long-term protection against volatile markets
  • Increased asset value: More attractive to tenants and investors
  • Regulatory readiness: Future-proofing against tightening carbon regulations
  • Sustainability credentials: Supporting ESG targets and reporting

Why many still miss the opportunity

Despite strong returns, adoption is often delayed due to:

  • Outdated assumptions about cost and payback
  • Lack of awareness of usable roof capacity
  • Perceived complexity of installation
  • Competing capital priorities

However, with financing options, power purchase agreements (PPAs), and falling technology costs, many of these barriers are now significantly reduced.

A simple way to think about it – Every square metre of unused roof is effectively:

  • Generating nothing … or:
  • Each square metre of a commercial flat‑roof solar installation typically generates ~110–120 kWh per year, equivalent to ~£28–30 per m² annually at 25p/kWh. ,
  • That’s £687.50–£750.00 per m² of potential value, often from space that currently delivers none..

The Bottom Line

Solar is no longer a speculative investment. For commercial and large residential property owners, it is a proven, cash-generating asset with:

  • Predictable returns
  • Short payback periods
  • Long operational life
  • With EVERYTHING done for you

The question is no longer “Does solar make sense?”
It’s “Why leave that value sitting unused?”
