Note, of the above list, we should point out that the company with the highest TrustScore and one of the highest Google customer ratings, Efficient Home, is not the same as the large, national company of the nearly identical name, Effective Home, which is based in Yorkshire. There are a few larger, nation-wide installers based in London, including Joju Solar (TrustScore 4.3) and Evergreen Power Solar (TrustScore 4.4), who also have an office in Leicester.

The companies listed in the table above are based in London, have TrustScores of at least 4.6 out of 5 from at least 30 customer reviews, Google customer ratings of at least 4.4 out of 5 (where available) and are MCS certified.

The companies above can be a starting point for you with your research, but of course there may be other London installers more suited to your needs. The above list is meant to be a list of local companies based in London—but there are many other companies that are based elsewhere yet install in London.

Check Google maps for other solar installers in your area, and you can even contact neighbors with solar panels to ask about their installers. First-hand, personal recommendations can be a great source of information!

Should I use a local solar panel installer in London, or a national installer?

When deciding which type of installer to use, 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 discounts due to volume discounts
  • Deep product knowledge (e.g. if they only work with a limited set of products)

A national 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)

In addition, the national companies tend to have been in operation longer, whereas some of the local companies are quite young, and less established.

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 London solar panel installer

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
  • Hand holding their customers
  • Having your company nearby in case of problems
  • On site quotes and surveys (vs remote)
  • Sourcing specific equipment you desire (they may be less likely to have established partnerships with specific manufacturers)

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
