About Us

Security, Environmental & Electrical Engineering Consultancy

Situated in Ringwood on the South Coast of England but with a nationwide remit se3c provides both electrical design and project management services within the construction and service industries.

We are proud of our status we have gained for detailed design, problem solving and ensuring project delivery. Our engineering experience covers many sectors allowing se3c to develop an industry leading skill set in bespoke solutions, tailored to our Client’s needs.

Who We Are?

Se3c was formed in 2016 by two brothers Lister & Philip Wills who have independently worked in a vast range of service industries from Nuclear to Rail/Airports but always with an electrical design/project management role. We’ve teamed up to form se3c and offer a combined electrical project management service.

Our Mission

“Work and live a balanced life and apply ethical principles to make a significant difference”

Our Approach

System design works are undertaken by degree educated Chartered Electrical Engineers having long-term experience of working within both commercial building services industries regulated & highly serviced environments.

Our projects are run with the formal structure defined from Prince 2 but tailored to the specific requirements of our Client’s.

Meet The Team

As with any progressive company the people are its strength and that’s our philosophy at se3c. Highly skilled and motivated personnel providing an unrivalled service and support along with an extremely high level of detail from concept to completion.

Se3c blends together both electrical design and project management, with over 40 years of combined experience we offer an independent, multi-disciplined modern, forward thinking consultancy with a strong ethical approach to our business.


Phil has eighteen years of experience as a Project Manager having undertaken extensive technical projects within the electronic security and airport parking environments. Qualified with both Prince 2 project management skills and a degree in electrical & electronic engineering Phil aspires to ensure that projects are delivered on time and within budget.

With his ability to lead teams from the design phase to apply risk mitigation measures and to develop project planning schedules Phil’s responsibilities included the production of project programmes, financial progress reports and review of key performance indicators.

His most recent projects have been within the airport sector, mainly at Heathrow and Gatwick Airports, where project planning and financial control are considered paramount to achieving the high levels of safety and security required by major airports. Good Project Management providing clear direction is essential in ensuring these objectives are met within the highly regulated environment of an airport.



Working as a Chartered Electrical Engineer for twenty five years Lister has latterly undertaken high integrity design work for several electrical schemes (EC&I) to high hazard installations which have been subject to regulation via the HSE and ONR. This has included working within both the civil nuclear power sector, on the new EDF Hinkley Point ‘C’ station and within the defence sector on multiple nuclear and explosive projects at AWE.

In addition to the systems engineering and life safety doctrine gained from this experience Lister’s previous role, as Associate Electrical Engineer to a commercial building services consultancy, has provided him with knowledge of value engineering and project delivery. Being technically adept with a thorough understanding of new legislation is a key requirement for the design of modern buildings and electrical systems as they continue to become more complex and highly serviced. It is this aspect of electrical design, encompassing environmental and security best practise that interests Lister.
