Solar PV in-roof installation

Why choose a Solar PV system?

Solar PV can cut your electricity bills and reduce your carbon footprint. Getting started is easier than you think.

Our free online tool gives you an instant estimate of how much energy you could generate and save, simply by mapping your roof space. Then, for complete accuracy, we carry out a professional home survey. You’ll receive a clear, fixed price and friendly, expert advice tailored to your home.

As an MCS and RECC accredited installer with over 9 years as a Which Trusted Trader, Gregor delivers high-quality solar installations you can trust.

Your system could be installed in as little as 2 weeks, helping you start saving sooner.

A sustainable choice

With energy prices continuing to rise, Solar PV also helps protect you from future cost increases, giving you greater independence and control over your energy use. And when combined with other technologies such as battery storage, you can maximise your savings by storing surplus energy to use later, reducing your reliance on the grid even further.

At Gregor, we believe in building a greener, more sustainable future and with over 9 years accredited by Which?, MCS certified since 2013, and long-standing members of RECC, you can trust us to deliver not just solar, but complete renewable energy solutions tailored to your home.

Frequently Asked Questions

In most cases, no. Solar PV is considered “permitted development” for homes, so planning permission isn’t usually required. The only exceptions are if you live in a listed building, a conservation area, or have specific local restrictions.

A typical home Solar PV system can be installed in 1–2 days, depending on roof size and access. From survey to switch-on, the whole process is usually completed within 2–3 weeks.

Yes. By generating your own electricity, you’ll reduce the amount you need to buy from the grid. How much you save depends on your usage and roof size, but many homeowners see significant reductions in their electricity bills from day one.

Any excess electricity can be exported back to the grid, and with the Smart Export Guarantee (SEG) you may get paid for what you export. If you add battery storage in the future, you can store surplus energy for use later, maximising your savings.

Solar PV systems are very reliable and typically last 25 years or more. Most panels also come with performance warranties, giving you peace of mind that your system will generate energy for decades.
