I got a quote for a solar PV and battery install back in September 2022 and was provided assurances that all certification (including MCS) would be provided on completion. Having paid a 30% deposit I learned that Hassle Free Boilers (now called Koze Home) are not MCS accredited for solar PV installations. Concerned by this news I immediately requested to terminate the contract on the basis of Hassle Free Boilers miss-selling their ability to provide an MCS certificate for my installation in the contract. Reluctantly they agreed, however the refund amount was paid a week late (after their already generous 30-day refund policy) and only following 15+ phone calls a day and threats of legal action against them. When the refund was paid to me after 35-days I noticed a fee of £240 was deducted which I challenged. Not hearing anything back from Hassle Free Boilers after many emails and attempted phone calls I was forced to submit a small claims court summons to Hassle Free Boilers. Thankfully the final element of my deposit was paid shortly after their court summons arrived and I terminated my claim against Hassle Free Boilers. So in summary, AVOID HASSLE FREE BOILERS AT ALL COSTS, they will: - promise you everything and deliver you nothing - lie to you about MCS accreditation for solar PV in the contract - take your money freely but only refund your money once legal action against them is taken
