Allan Pickard • Leicester, UK

"My mum had some awful experiences with other loft companies, who kept letting her down and not carrying out the work properly, which ended up costing her even more money. From the moment I spoke to Dean, I felt completely reassured. He was at my mum’s house within the hour, identified the problems straight away, and sent clear video evidence explaining exactly what needed to be done. Dean’s professionalism, knowledge, and customer service were absolutely fantastic. He took the time to explain everything clearly and gave us confidence that the job would be done properly. I wouldn’t hesitate to recommend Next Generation Insulation to anyone looking for an honest, reliable, and professional company. 5 stars!"

"Dean arrived promptly for the survey appointment and provided a very full description of the work needed and the method of execution of the undertaking. Kirsty and Luke provided great assistance in providing the detailed information of the technical aspects of the work and the follow up information. Brett and Grant arrived on time and immediately prepared the property for the work to be undertaken. They worked extremely hard over the 2 days and ensured that the work was completed to a high standard and that the property was left immaculately clean and tidy. All aspects of the job were undertaken to the high standards described in the initial proposal provided by the company. My wife and I are extremely grateful to Brett and Grant who undertook to remove the heavy items from the loft and to return them to the loft on completion of the job - a great gesture to assist elderly customers and certainly not part of the job description. My sincere thanks to all at Next Generation for their excellent customer service."

"Firstly is the most Dean approachable contractor I have ever worked with and I do for a living! When we reached out to him about the difficulty we were having making a sale with my mum‘s loft (spray foam insulation) he was honest and open and keen to help. Having to do everything remotely from 300 miles away was a real challenge, but Dean and his team did everything possible to make it work. The loft had closed cell insulation onto a non-breathable membrane. We had quotes from so many people and none of them were the same (some promising things that were cheaply priced around 3k but sounded unrealistic and only when pressed did we hear things like “50% success rate” and then bigger price tags emerging- up to 25k!) We were recommended Dean by a surveyor who had seen his Work previously and said it was the best cleanest Work he had seen and there were no problems getting a mortgage once he had done the work. Dean was the 1st to provide us with clear evidence of the testing he done. He showed us why we couldn’t have ice blasting without damaging the roof. He explained what was needed was a full removal and replacement - we went for a new roof with dark tiles as this had looked very good on neighbouring properties. His pricing was very fair and reasonable for the work he proposed. Dean answered so many calls with many questions and always dealt with things personally. They repaired anything that needed it along the way and did a fantastic job tidying up knowing we are trying to sell. The roof looks amazing and we felt genuinely supported every step of the way. The work was completed very fast and they were very popular with the neighbours, they started a new roof trend on the street- everybody wanted one! We are very hopeful that we get a sale quickly now this is done and will update this review following that with how it went with his guarantee and the surveyors etc. Overall Dean and his team were true lifesavers."

"We recently used Next Generation Insulation to diagnose the cause of damp in our loft and provide the right solution. Dean was very clear and knowledgeable, and I’m confident he correctly identified the issue and recommended the best course of action. As the team specialise in both insulation and roofing, they were able to take a holistic view and find the right solution, rather than simply suggesting work that would benefit them. They removed the wet insulation from my loft, carried out mould removal and preventative treatment, and then correctly installed new insulation. The work was completed over two days with a large team on site, all of whom were great lads. The work was delivered to a very high standard, with real care taken to protect my property and leave everything clean and tidy. Honestly, they are the best tradesmen and company we’ve come across in a very long time. I wouldn’t hesitate to recommend them or use them again for any future work."

"I have recently used Next Generation Insulation (NGI) to remove spray foam from my loft and re lay new insulation. They have done an exceptional job, from protecting all the carpets to completely cleaning up after themselves and doing everything to a very high standard. They always arrived on time and kept me fully informed when anything unexpected occurred and the guys doing the work were a pleasure to have in the house. I have no hesitation in recommending them."
