Glow Green
A point of note about Glow Green: Glow Green is based in the South West (Bournemouth, specifically)—but they operate as one of the largest UK solar panel installers in the country. In fact, according to Companies House filings, Glow Green has historically reported annual turnovers in excess of £24 million. Around since 2011, they are very well established.
(Note: Total Renewable Solutions has been around nearly as long—since 2012).
Should I use a local solar panel installer in London, or a national installer?
When deciding which type of installer to use—smaller, local vs. larger, national—here are some factors to keep in mind:
Pros and cons of using a national company
A national company might be better at the following:
- Quick quote turnaround
- Offering lower prices due to volume discounts on hardware
- Deep product knowledge (e.g., if they exclusively work with a limited set of flagship products)
A national company might be worse due to the following:
- Installation teams might be outsourced/contracted out to third parties
- Limited manufacturer options (e.g., some install only one or two types of panels)
- Quote and technical survey might be conducted online or over the phone (not on-site)
One other point to keep in mind: ideally, your installer will remain in business for years in case you need them again or have a warranty claim. National companies tend to be better established, whereas some of the local companies are quite young.
Note: 'Online' or 'phone-only' quotes and technical surveys are great for efficiency—you can get a quote in literally minutes. But an on-site technical survey can save you time in the long run and helps ensure the system you get is truly optimised for your home. For example, it can be difficult for remote software to accurately estimate how many panels can actually fit around complex roof lines. If your roof is small compared to your energy needs, you need a physical survey to safely maximise the panel count.

Pros and cons of using a local SW company
A local company might be better at the following:
- Installation teams are much more likely to be in-house staff (as opposed to contracted out)
- Knowing the 'sunniness' and specific weather realities of your coastal or inland area
- More personalised "hand-holding" customer service
- Having your company nearby in case of problems or hardware faults
- On-site quotes and surveys are the default (vs. remote)
- Sourcing specific equipment you desire (they are often more open to installing your choice of panels)
A local company might be worse due to the following:
- Quote turnaround and installation wait times might be slower
- Because they do less volume, they may not be able to pass on the massive bulk-buy discounts that national brands offer
