Solar panel installation companies can vary widely in quality and reliability, so it helps to know what to look for before you commit. In the UK, one common red flag is high-pressure sales tactics, such as insisting you sign immediately or offering “limited-time” discounts. Another warning sign is a lack of clear documentation, including no written quote, no breakdown of costs, or no details about warranties and guarantees.
It’s also worth checking whether the company is registered with recognised industry bodies, and whether they can provide references or examples of previous work. If a business is vague about product specifications, uses unfamiliar brands without clear information, or can’t confirm who will be responsible for the installation, it’s usually best to look elsewhere. Finally, always compare at least two or three quotes to get a clearer sense of what a reasonable price and service level should look like.
