Getting solar panels installed? Planning a rewire? Not sure if a contractor's quote is fair? We provide honest, independent advice to help you make confident decisions — without trying to sell you anything.
We don't install anything or sell equipment. Our only interest is making sure you get the right advice and a fair deal.
Every service has a clear, fixed price. You know exactly what you'll pay before we start.
Our consultant started as an electrician and worked their way up to designer. They know what good work looks like — and what bad work looks like.
All services include a written report you can share with your installer or contractor. We explain everything in plain English — no jargon, no waffle.
Had a solar panel quote? We'll independently review the proposed design to check it's properly sized, correctly specified, and BS7671 compliant.
Planning a rewire? We'll assess what you actually need, help you plan the scope of work, and make sure you're not paying for unnecessary extras.
Not sure if a quote is fair? We'll review what's been proposed, flag anything that looks wrong or overpriced, and tell you what questions to ask.

I've spent 20 years in the electrical industry. I started as an apprentice electrician, worked my way through installations, and moved into electrical design. I've seen every kind of job — good, bad, and dangerous.
I started ZESTEC because I kept seeing homeowners getting poor advice, paying too much, or agreeing to work they didn't understand. There was nobody offering independent, jargon-free guidance without trying to sell them something at the same time.
I'm not here to sell you solar panels or a rewire. I'm here to make sure that whatever you're having done, it's right, it's safe, and it's fair. If your contractor's quote is spot on, I'll tell you that too.
It depends. If you've had a quote from an MCS-accredited installer with good reviews, the design is likely fine. But if you've had multiple conflicting quotes, or something doesn't feel right, a £150 review could save you thousands in rework. Think of it as a second opinion from a GP before surgery.
Most reviews are completed within 3–5 working days. You'll receive a written report by email with clear findings and recommendations.
That's absolutely fine — and it happens. Our report gives you the technical basis for the conversation. A good installer will welcome an independent check.
No — and that's the whole point. We're completely independent. We don't install anything, sell any products, or take referral fees from contractors.
Absolutely. We offer a free 15-minute initial phone consultation for all services. No obligation.
We work remotely across the entire UK. Since our service is design review and consultation rather than physical installation, we can help homeowners anywhere.
