What is MCS certification and why does it matter?
MCS — the Microgeneration Certification Scheme — is the recognised quality mark for small-scale renewable installations in the UK. An MCS-certified installation meets recognised industry standards for product quality, installation competence and aftercare. MCS certification may also be required for certain export arrangements or benefit schemes. We do not claim MCS certification for ourselves — we install through MCS-certified partners, so your installation is carried out to MCS standards.
Should I get multiple quotes?
It is sensible to compare quotes from different installers. When comparing, look at what is included — not just the headline price. A proper quote should specify the system size in kWp, panel make and model, inverter type, battery capacity if included, mounting system, scaffolding, and electrical connection work. The full installed price should be shown at 0% VAT. A no-obligation survey and written quote lets you compare like for like and decide in your own time. See our cost guide for what factors to compare.
What should a written quote include?
A proper quote sets out the recommended system in detail: panel array size (kWp), panel make and model, inverter type and capacity, battery capacity if requested, mounting system, scaffolding requirements, and any electrical connection work such as a consumer unit upgrade. It shows the full installed price at 0% VAT, with no hidden extras. It also states warranty terms — manufacturer warranties for panels, inverter and battery, and workmanship warranty for the installation. If a quote is vague about any of these, ask for clarification before proceeding.
What sales tactics should I avoid?
Be cautious of any installer who pressures you to sign on the day, offers a discount that expires immediately, or refuses to leave the quote with you to consider. A reputable installer gives you a written quote and lets you decide in your own time. Also be cautious of installers asking for large upfront deposits before a survey or full payment before work begins. Our surveys and quotes are completely no-obligation — you take the quote away and decide when you are ready. See our How It Works page for our process.
What about warranties and aftercare?
Solar panels typically come with a 25-year performance warranty. Inverters may need replacing after 10-15 years and come with their own manufacturer warranty. Battery storage lifespan is typically 10-15 years with a manufacturer warranty. Installation workmanship is covered by our partner. After installation you receive documentation for your system, and support is available if you have questions once the system is live. All warranty terms should be clearly stated in your quote.
