SolarQuote Check UK is a £29, one-time browser tool for UK homeowners comparing two current written residential solar PV quotes. It does not rank installers, read uploaded documents, predict generation, or recommend a system. You manually enter each quote’s total, array and battery sizes, installer-stated generation and savings, warranties, and included or unclear work. The tool aligns those entries, calculates cost per kWp and quote-provided simple payback, then highlights missing scope and conflicting assumptions. Inputs remain in your browser, no account is required, and you can download your own comparison record. Installer documents, MCS standards, consumer guidance, and qualified professional advice remain authoritative. SolarQuote Check UK is owned and created by Wolven Tech. It helps turn two differently written quotes into comparable questions before contract or deposit; it does not assess roof suitability, verify installer claims, provide a savings forecast, or choose which quote you should accept.

Why this comparison exists
CMA guidance recommends multiple quotes and written clarity on product, installation, taxes, funding, and extra work. Current MCS solar PV standards expose generation and self-consumption assumptions. SolarQuote Check puts entered facts beside each other; sources remain authority.
Before paying
Compare total price, system and battery size, quoted generation and savings assumptions, warranties, and whether enabling work is included or unclear.
No. It aligns values you enter and exposes differences. It does not rank installers or assess technical suitability.
No. The displayed figure divides quoted price by installer-quoted annual savings. It labels the result as a quote assumption, not a forecast.
