  • I couldn’t be more impressed with Greg’s exceptional service! Despite the short notice, he managed to carry out the EPC inspection and prepare the full report all on the same day. His professionalism, efficiency, and attention to detail were simply outstanding. Greg made the entire process seamless and stress-free. I highly recommend him to anyone needing a reliable and swift EPC report – truly five-star service!

  • I had a wonderful experience with Daniel & Greg at Hollen+ while arranging an Energy Performance Certificate (EPC). I called on Monday afternoon, and within a day they had scheduled the assessment for the following morning. Greg arrived promptly, was professional, and maintained clear, friendly communication from start to finish. By first thing this morning (Wednesday), we already had the certificate in hand, smooth, fast, and stress-free. It’s rare to find such responsive and reliable service these days. Highly recommend Hollen+ for anyone seeking a seamless, efficient EPC process.
