Really helpful and made it easy for us to get a new energy contract sorted. Can be a little pushy with their expectations with getting documents sent to them.

Matt gave us a call when we were in our renewal window. Straight forward, easy to do and very transparent and polite throughout. No aggressive sales tactics like other brokers use! It'll be a few year... See more

Thank you so much! Elle’s basically a customer service superhero minus the cape (we’re still working on that part). We’re so glad she made everything smooth and stress-free for you. She’ll be grinning from ear to ear when she sees this!

Thanks so much for the lovely feedback! Ellie runs on equal parts caffeine and customer care, so she’ll be thrilled to know her hard work paid off. We’ll make sure she gets the praise she deserves (and maybe a biscuit or two)!

I’ve had the pleasure of meeting David…

I’ve had the pleasure of meeting David at several HR and People-focused events over the past few years, and he always stands out for his deep knowledge and genuine enthusiasm for the profession.

David has an exceptional grasp of the current UK employment market and a strong understanding of the evolving Employment Rights Bill and its practical implications for organisations. What’s particularly impressive is his ability to discuss these topics in such an engaging and relatable way, making complex HR and legislative changes accessible to a wide range of audiences.

He’s the kind of HR professional who is always learning, sharing insights, and contributing meaningfully to conversations about the future of work and organisational development.

If you’re ever in a room discussing the changing world of HR chances are, David will be there, adding real value to the conversation.

What a brilliant review, thank you! You’ve summed up David perfectly. If there’s an HR event happening, there’s about a 99% chance he’s there (probably mid-conversation about the Employment Rights Bill with a coffee in hand). We’re lucky to have someone who makes the complex world of HR both insightful and enjoyable. Thanks again for sharing such kind words!

Rated 5 out of 5 stars

Fantastic service & advice delivery

I wanted to take a moment to highlight the incredible work David does within the world of Human Resources and People Development. His depth of knowledge and passion for the ever-changing UK employment landscape is genuinely impressive.

David provides clear, engaging, and up-to-date HR advice, always grounded in the latest legislation — including the recent updates within the Employment Rights Bill. What really stands out is his ability to translate complex HR and legal changes into practical, people-focused strategies that truly make a difference in the workplace.

It’s inspiring to see someone so dedicated to keeping organisations compliant, informed, and future-ready — while never losing sight of the human side of HR.

If you’re looking for insightful HR guidance or want to stay informed about the latest employment trends, David is definitely someone worth connecting with.

What a fantastic review , thank you! We’ve always said David’s brain must have an HR encyclopedia built in, and it’s great to see others think the same! He’ll be over the moon to hear this (and probably quoting legislation in celebration). Thanks again for sharing such lovely feedback!

Outstanding Service and Great Business Rates Thanks to Nathan

Renew & Sustain offered excellent business rates and made the whole process smooth and easy. Nathan, the customer service agent, was polite, professional, and clear from start to finish. He explained everything in detail and made sure I understood every step.

He secured a great deal for my company and handled all the supplier communication quickly and efficiently. It’s rare to find both great prices and genuine customer care in one place.

Highly recommended for any business looking to save money and work with a trustworthy consultant.

Outstanding Account Management and…

Outstanding Account Management and Energy Rate Optimization by Nathan Harvey

I recently had the pleasure of working with Nathan Harvey to help my business secure the best energy rates, and I couldn’t be more impressed with his level of service and expertise. From start to finish, Nathan was extremely thorough in understanding our energy needs and business operations. He took the time to explain the different rate options available and guided us toward the most cost-effective solutions for our specific situation.

What stood out the most was Nathan's excellent account management. He was always responsive, proactive, and easy to communicate with, ensuring a smooth process throughout. He not only helped us find the best rates but also went the extra mile to ensure we fully understood the contracts and terms. I felt confident every step of the way, knowing Nathan was looking out for our best interests.

If you’re looking for someone who is professional, knowledgeable, and committed to getting the best possible energy rates for your business, Nathan is your go-to person. Highly recommend!
