Sustainability Consultancy – Meet the Team

Sustainability Consultancy – Meet the Team

We are very pleased to introduce you to the Hannan Sustainability team.

As Building Services Engineering Consultants sustainability has always featured at the heart of our design process.

Hannan provides a wide range of sustainability consulting services to support our clients to shape and define strategies to achieve site specific and corporate Sustainability targets including:

  • Net Zero Carbon
  • NABERS UK & Energy Performance Modelling
  • Building Certification
  • LCA and LCC Studies.
Name: Tim Bell
Role: Head of Sustainability
How did you end up working in sustainability?

A long time ago, I worked with my Dad in California, where we designed and built bespoke homes. It really piqued my interest in construction. From there I took an MSc In Construction Management and Economics at UCL, where sustainability was touched on, before moving into consultancy working on Life cycle costing projects. It just happened one day that I supported a project team on a BREEAM project and found the various subject areas to be very interesting. From there I haven’t really looked back, and my focus was fixed firmly on sustainability.

What do you enjoy the most about your job and what do you find the most challenging? 

The variety of project types makes the job interesting and certainly as more of our clients are looking at Net Zero and decarbonisation there is a wider variety of sustainability topics to focus on rather than purely certification. This allows us to add value. Managing several projects can be challenging whilst ensuring that what Hannan provides to our clients is of the very highest quality.

How has the industry changed since you first started your career?

Well it’s changed dramatically. I remember sitting in meetings 20 years ago and being asked ‘Sustaina…what?’ Now obviously, climate change, decarbonisation and net zero are everyday terms and key drivers for the built environment. Importantly all these issues are being discussed, taught in schools, highlighted in the media and the younger generation, on the whole, are much more aware of the situation we find ourselves in and keen to make a difference. The built environment is now defined by sustainability and developers and investors are motivated to deliver and invest in ‘green’ assets as tenants become more particular about the buildings they want to work in.

What changes do you foresee for the next 20 years?

Embracing innovation, sustainable supply chains and procurement, the continued rise of the circular economy and more focus on the economic and social impacts of sustainability such as community engagement. As the climate crisis becomes increasingly complex, customers will also be more cautious about their own carbon footprint and will question if a product is sustainably sourced or produced.

What do you enjoy doing in your spare time?

I try to live a relatively active lifestyle and have recently taken up Padel and play as often as my knees allow. I’ve basically got all the gear and no idea! Just being with my wife Sarah and daughter Esme. Long walks in Formby Pinewoods and on the beach with Indy our dog. And got to put it out there, I’m a lifelong LFC supporter so try to get to Anfield when I can and having grown up in California, I also have a great passion for baseball and American Football. 

Name: Charlotte Becker
Role: Graduate Sustainability Engineer
Which training route did you take?

I completed a BSc (hons) in Environmental Science and an MSc in Environmental Sustainability and Green Technology both at Keele University, before spending a year gaining industry experience working in environmental consultancy.

What do you enjoy about your job?

I enjoy the fact that I am able to apply my passion for the environment to projects that can produce real-world positive impacts such as preventing greenhouse gas emissions or making improvements to the local environment which can be very rewarding. I also enjoy the wide variety of tasks and projects I get to work on in the role of Graduate Sustainability Engineer, as well as being able to play a part in the transition towards sustainable development that encompasses all aspects of sustainability from material efficiency to ecological enhancement. 

What do you enjoy about working at Hannan Associates?

I enjoy the friendly and supportive atmosphere at Hannan Associates and being able to work with, and learn from, a range of different people who are very knowledgeable in their respective disciplines. I also enjoy the variety of training opportunities I have been given since working at Hannan Associates which have enabled me to develop my skills and understanding and have put me on a path to becoming a recognised sustainability professional.

What do you enjoying doing in your spare time?

I like to spend much of my spare time with my family and friends as well as staying active by going running and doing gym classes.

Name: Matt Dalley
Role: Senior Energy & Sustainability Consultant
How did you end up working in sustainability?

The Kyoto Protocol was signed in December 1997. In 1998, at the age of 16, I applied to study A-Levels in Environmental Science, Geography and Geology.  This led me to study for a degree in Environmental Protection and then read for an MSc in Sustainable Development.

What do you enjoy the most about your job and what do you find the most challenging? 

I enjoy seeing the evolution of sustainable building design and the finished building.
The challenge is changing the existing mindset of designers and contractors towards sustainability.

How has the industry changed since you first started your career?

Sustainability has gone from being a fringe concept to a core requirement. Clients and tenants now understand the climate issues and expect a high level of sustainability in their buildings.

What changes do you foresee for the next 20 years?

The move to zero carbon and the use of operational energy models / in-use energy data will become a driving factor in building design.

Any advice for people looking at starting a career in building services engineering?

A career in sustainability can be rewarding, but there are still many challenges. As with many things, the barrier of cost requires a compromise between sustainability and affordability.

What do you enjoy doing in your spare time?

Hiking/camping /DIY.

National Apprenticeship Week 2024

National Apprenticeship Week 2024

To celebrate National Apprenticeship Week, we caught up with past and present building services engineering apprentices here at Hannan Associates to see what they had to say about their experiences.

George Ellison – Apprentice Electrical Design Engineer

George joined Hannans in 2023 when he started his BEng Degree Apprenticeship in Building Services & Sustainable Engineering after completing his HNC and Level 3 BTEC Extended Diploma in Construction & the Built Environment.

Why is undertaking an apprenticeship the right route for you?

Undertaking a degree apprenticeship is the right route for me as I’ve been able to study for a well-recognised qualification whilst also gaining valuable experience in the workplace.

It’s also a great opportunity to earn money whilst completing your studies. The exposure you get being in the workplace on a day-to-day basis weather that be learning software, attending site visits or meetings, these are all skills which being an apprentice helps build and prepare you for the future.

I enjoy being able to play my part in making a positive impact on the way buildings work/perform, the problem-solving aspect of the job and I also enjoy the demand of it i.e. being kept busy at all times.

My future aspirations would be after completing my Degree to become a well-recognised chartered Electrical Engineer.

What do you enjoy about working at Hannans?

I enjoy the spirit of the team here at Hannan’s, everyone has been extremely welcoming which has made it easy for me to work to the best of my ability at an early stage. There is also a vast range of projects and certainly ones which I have an invested interest in i.e football stadia.

Any advice for people looking at starting a career in building services engineering?

My advice for people considering going into Building Services Engineering would be if you enjoy problem solving and feel as though you would thrive in a fast paced, evolving industry then go for it. It’s a career which will allow you to experience a variety of interesting projects, seeing how they progress from a patch of land all the way through to the finished article.

Brad Spivey – Electrical Design Engineer

Brad joined Hannan Associates seven years ago as an apprentice. He completed his Building Services Engineering HNC at Stockport College and then progressed onto the BEng Degree Apprenticeship in Building Services & Sustainable Engineering at the University of Central Lancashire, which he completed in 2022.


During his time with the Hannan team Brad has developed into a highly skilled, client focused and motivated electrical design engineer contributing to the success of his projects by ensuring that client needs are met at all stages, during design and construction and by ensuring that energy efficiency is always considered and incorporated.

Brad has helped lead several utilities infrastructure projects by producing utility load assessments, reviewing existing infrastructure services and diversion requirements, identifying initial utility space and route requirements, submission of utility applications as well as monitoring utility installations on site.

Why was undertaking an apprenticeship the right route for you?

The apprenticeship route enabled me to train on the job with the luxury of studying one day a week at college & university helping to make my studies much more relatable.

This allowed me to progress academically whilst gaining experience and progressing my career.

What do you enjoy about working at Hannans?

I have worked as an electrical engineer at Hannan Associates for seven years starting out as an apprentice. During this time, I have worked on stadia, industrial warehouse parks, leisure, office and infrastructure projects as well as regularly attending site to complete site inspections and witnessing of systems to ensure all systems are adequate for handover. Everyone at Hannan Associates is helpful and works as a team to ensure that projects are delivered on time to the required standards.

Any advice for people looking at starting a career in building services engineering?

My advice firstly would be research the building services industry and decide if it’s right for you. Building services has a big role to play in the future due to the need for reducing both existing and new build CO2 emissions whilst ensuring the sustainability needs of buildings are met. This could be your chance to contribute and make a difference both locally and on a larger global scale.

My advice personally to anyone looking to get into building services would be work hard and don’t give up if you make a mistake or don’t achieve something at the first attempt.

40 Years of Hannans: Q&A with John Walker

40 Years of Hannans: Q&A with John Walker

Name: John Walker

Role: Director

Tell us a little bit about how you came to join Hannan Associates and what it was like when you started.

The previous director decided to emigrate to New Zealand and I responded to a Hannan advertisement for an Electrical Director Designate.

I was interviewed by Bill, Heather and Ian and was lucky to land the position.

Hannan Associates was a successful business with a good reputation when I joined but I could see there were areas of improvement needed to underpin the success and move it forwards.

There was too much focus on Bill Hannan as an individual and not enough on the other talented people in the business so we began to market the wider skills base with clients.

How has the business changed since you joined?

The Business relocated to a new office in Denton which showcased some of the ideas and technologies we were recommending to clients at the time.

The design processes and the skills we require have evolved, driven by the availability of design software and faster computer technology.

Sustainability and the need to improve the performance of buildings has significantly enhanced our role within the design teams and our relationship with the architect.

The increased complexity of developments and buildings has resulted in more specialists being required within the team and we now offer a much wider range of services to clients to meet this demand.

We now operate successfully in a wider range of sectors some of which have been planned and some has been in response to repeat client requests.

What do you think has been the key to keeping so many long-term clients happy over the years?

Everyone in the business is aware of how important it is to keep repeat clients happy and has a good understanding of what it takes but I think it goes beyond that because our people are genuinely interested in delivering what is needed for success on the projects even if that means stepping outwith our scope and I think clients recognise this.

In terms of the process for us it includes; helping to define our own scope, self management, building relations with the team, flexibility, commercial awareness, technical competence, meeting deadlines, good communication and delivering value on fees.

What do you think the next ten years holds for Hannan Associates and the industry?

The focus on sustainability will continue to offer significant opportunities as we approach the worldwide carbon deadlines for 2030 and beyond.

The pace of change looks like it will be the main challenge for us over the coming years. If we are to take advance of the opportunities we will need to embrace and master the new technologies and design tools which are likely to include AI.

Construction needs to be more diverse and whilst we have moved forwards there is much more to do.

What are you most proud of in terms of your contribution to the business? 

The systems and processes which we have implemented to help us deliver our services.

The successes we’ve had with the people who joined us a graduates and trainees – even the ones who moved on.

The freedom enjoyed by the staff and the absence of red tape and bureaucracy.

The stability of the company and the way we have responded UK and World recessions.

Energy Strategy

National Policy, local legislation and the Clients’ sustainability policies will operate to reduce energy demand and CO2 emissions, enhancing the sustainability credentials of the development.

Each of the plots has been designed with the aim of reducing operational energy and carbon emissions, and as such, each is employing a fossil fuel free all-electric strategy, with no provision of mains gas to the development.

Passive measures have been prioritised to reduce energy demand, including enhanced fabric performance and air permeability, along with optimised glazing design.

Active measures have been taken to optimise the energy efficiency of fixed base build systems, i.e. Mechanical ventilation incorporating heat recovery, low flow sanitaryware, energy efficient LED lighting and controls systems.

Low & Zero Carbon Technologies have been incorporated where applicable in the form of high efficiency heat pumps to generate space heating, and allocation of dedicated zones at roof level for installation of a PV array.


Plots A, B & C have been designed to achieve a minimum of BREEAM ‘Excellent’ rating.

Hannan Associates Appointment

We are working on behalf of the Client to;

  • Assess works associated with existing utilities networks to accommodate the new development proposals.
  • Consult regarding new utility supply requirements.
  • Provide MEP design duties for each plot and the associated public realm.
  • Assess the anticipated building performance using operational energy modelling techniques.
  • Undertake the BREEAM assessments for the relevant plots.

Hannan Associates are working in conjunction with Jon Mathews Architects, Chroma, Civic Engineers, MAC Construction Consultants, Hoare Lea, DFC & Asteer Planning.
