Are you not sure if you should go with a large UK or a smaller, local company? Below we discuss some of the pros and cons of each.

Should I use a local Welsh solar panel installer or a large UK-wide 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 larger company

A larger, UK-wide company might be better at the following:

  • Quick quote turnaround
  • Offering discounts due to volume discounts
  • Deep product knowledge (e.g. if they only work with a limited set of products)

A larger company might be worse due to the following:

  • Installation teams might be outsourced/contracted out
  • Limited solar panel manufacturers only (e.g. some install only 1 or two types of panels)
  • Quote and technical survey might be online or phone only (not on site)

Note: 'online' or 'phone'-only quotes and technical surveys can be good for efficiency—you can get a quote in literally minutes. But an onsite quote and technical survey can save you time in the long run and help ensure that the system you get is truly optimised for your situation. For example, in some cases it can be difficult for online or over-the-phone quotes to accurately estimate the number of panels that can actually fit on a roof—this may or may not be a factor for you. If your roof is small compared to your needs, then you need to maximise the panels on the roof.

Pros and cons of using a local Welsh company

A local company might be better at the following:

  • Installation teams might be more likely to be in-house (as opposed to contracted out)
  • Knowing the 'sunniness' of your area (and therefore what power generation can really be achieved)
  • Hand holding their customers
  • Having your company nearby in case of problems
  • On site quotes and surveys (vs remote)
  • Sourcing specific equipment you desire (e.g. they may be more open to installing your choice of panels)

A local company might be worse due to the following:

  • Quote turnaround might be slower
  • If they do less volume, they may not be able to pass on bulk discounts to customers
