Who We Are

Energy Lock is a retrofit/home energy consultancy that believes making changes to a property to boost energy efficiency should be straightforward, expert-led and client-focused.

We want our clients to feel empowered, informed and at ease after approaching us for energy advice or retrofit work. That’s why we guarantee that if you instruct us to carry out work to meet your energy needs, your project will undergo a rigorous quality assurance process, with all work personally approved by Energy Lock before completion. You’ll also have one clear point of contact so you know who to call to get answers to your questions. This is the Energy Lock Guarantee.

Our Story

Founded in 2022, Energy Lock (known then as L.Retrofit) was set up as a home energy consultancy to serve the changing needs in the construction industry.

UK homes contribute to 20% of the carbon dioxide in our atmosphere, and in order for the UK to reach Carbon Net Zero by 2050, the UK government needed qualified professionals to make changes to thousands of buildings that would mean they use less energy.

With 15 years in architecture and project management, Energy Lock founder, Leanne Madden, was perfectly placed to gain retrofit accreditation and satisfy a growing list of clients who want to make fundamental changes to a building to make it more energy efficient.

Our Mission

Put simply, we want to help you contribute to a net zero nation.

What does this mean?

It doesn’t matter if you’re a homeowner looking to reduce your long-term energy bills or a property manager trying to achieve a higher EPC rating, we want the same thing; to make your property more energy efficient.

The best bit?

We’ve got the expertise to make your energy efficiency dreams a reality.

Every year we put plans in place to help homeowners save thousands of pounds in energy bills.

Our phased approach to Whole House Plans ensures that homeowners and housing associations can balance comfort with cost so they can utilise their budgets, or unlock the funding they need.

Whatever your priorities, we can help you make UK homes healthier and more comfortable, energy bills more affordable and contribute to a net zero nation.
