Next Generation Insulation is a specialist nationwide roofing and energy efficiency helping homeowners across the Midlands and the wider UK with spray foam removal, loft insulation, roofing solutions, and property energy efficiency improvements.
We combine practical roofing knowledge, careful project management, and clear communication to help homeowners protect their properties and make informed decisions.
Our work is especially important for customers dealing with spray foam insulation, mortgage concerns, property sales, remortgages, inherited homes, or roof condition issues.
Next Generation Insulation was founded by Dean Simpson, who has built his career around sales, marketing, business development, and property improvement.
Before starting the company, Dean was involved in property renovation and HMO conversions. That experience gave him a practical understanding of buildings, trades, project management, and the importance of doing work properly rather than cutting corners.
It also helped him build strong relationships with skilled and trustworthy roofers, electricians, joiners, plasterers, and other tradespeople. That network became the foundation for the experienced team behind Next Generation Insulation.
For Dean, the business has always been about more than insulation or roofing. It is about building a company based on integrity, accountability, clear communication, and long-term customer trust.
A major motivation for starting the business was family. As a father of two, Dean wanted the independence to build something he could be proud of while still being present for his family. That same sense of responsibility shapes the way the company treats its customers.
From the beginning, the goal has never been simply to chase the next job. The aim has been to improve homes the right way, raise standards in the industry, and create a business homeowners can rely on.
Corporate accountability and stringent standards define our operational framework. We align our services with leading industry bodies to guarantee complete regulatory peace of mind for our clients.
The modern property market presents significant challenges for buildings containing legacy insulation materials. Our entire operational workflow is explicitly designed to satisfy the rigorous criteria set out by surveyors, valuers, and major financial institutions.
To date, Next Generation Insulation has successfully executed over 227 spray foam removal projects. This portfolio includes 66 combined spray foam removal and structural re-roofing operations. Through meticulous documentation, we have maintained a 100% lender acceptance record across all completed projects, successfully facilitating property transactions and equity release applications with major high street lenders including Santander, Nationwide, and Barclays.

Because our core heritage is rooted in professional roofing, we hold a distinct advantage over standard insulation companies. If we uncover hidden structural defects during extraction, such as fractured purlins, degraded breathable membranes, or slipped tiles, we execute permanent, correct external roofing restorations. We never rely on temporary internal patches. Every structural adjustment is discussed transparently with the homeowner beforehand, ensuring absolute clarity with no hidden costs.
To guarantee complete asset protection, every client receives a comprehensive, mortgage-friendly digital asset portfolio upon project completion. Delivered via secure Google Drive links, email, or WhatsApp, this pack provides undisputed evidence of structural remediation for future property surveys:
Location: Little Haywood, Staffordshire
The Challenge: Retained via a direct recommendation from a satisfied client, we were instructed to inspect a historic 200-year-old cottage. The property had recently undergone independent assessments by both a specialist damp and timber surveyor and a chartered surveyor, with neither professional identifying structural defects behind the insulated timber envelope.
The Discovery: During the meticulous mechanical extraction of the spray foam, our technicians uncovered a critical, concealed point of failure: severe structural timber deterioration hidden directly beneath a low-level purlin. The roof structure was on the verge of imminent collapse, masked entirely by the polyurethane insulation.
The Solution: The project immediately transitioned from a standard insulation removal into a complex structural roofing operation. Prioritizing occupant safety, our team rapidly shored up the internal ceilings, erected temporary structural internal supports, and deployed full perimeter external scaffolding with complete weather protection roof coverings. Working strictly to structural engineering parameters, we dismantled the compromised segments, integrated new purlin supports, installed a modern breathable membrane with new structural battens, and completed a full external re-tile. This professional intervention saved a historic home, proving why deep roofing expertise is vital when dealing with volatile insulation environments.
Next Generation Insulation was built around a simple belief: homeowners deserve clear advice, honest communication, and work completed to a high standard.
Founder Dean Simpson brings together a background in business development, marketing, property renovation, and HMO conversions. That mix of commercial experience and hands-on property knowledge has shaped the company’s approach from day one.
Dean’s property background helped him build a trusted network of skilled tradespeople, including roofers, electricians, joiners, and plasterers. Today, that network supports a team built around professionalism, reliability, and high-quality workmanship.
The company’s growth across the Midlands and nationwide has been driven by that standard. Every project is approached with the same focus: understand the property, explain the options clearly, complete the work properly, and provide the evidence customers need after completion.
As Next Generation Insulation continues to grow, the company is investing in training, qualifications, and industry accreditations. The team is also preparing to support government-backed energy efficiency initiatives through the ECO Scheme.
The ambition is clear: to raise standards across the industry and become one of the UK’s most trusted specialists in spray foam removal, loft insulation, and roofing solutions.
For Dean, this business is about far more than insulation or roofing. It is about creating a company built on integrity, expertise, accountability, and long-term customer trust.
