Blog: Celebrating 5 years of growth

Warmer Energy Solutions is celebrating its fifth anniversary, marking a remarkable journey from humble beginnings in Managing Director’s dining room to delivering large-scale domestic retrofit programmes across the UK with over 4,000 retrofits completed to date.

Founded in 2020, Warmer Energy Solutions was established to be a specialist in retrofit delivery, dedicated exclusively to energy efficiency and decarbonisation rather than juggling decarbonisation with legacy fossil fuel heating contracts. With this single-minded focus, Warmer Energy Solutions has built a reputation as a leading national provider of turn-key retrofit delivery that supports both social housing providers seeking to maximise Warm Homes: Social Housing Fund grants and homeowners accessing support through ECO, Boiler Upgrade Scheme (BUS) and other government-backed schemes.

From its start-up roots, Warmer Energy Solutions has grown rapidly, now employing a dedicated team across three office locations, including new headquarters at Liverpool’s Estuary Business Park. This expansion has enabled the business to invest in its people, creating high-quality working environments and the capacity to deliver retrofit at scale.

Charlie Mullan, Managing Director, said: “With the UK government committing over £13 billion to decarbonising domestic properties during this parliament, Warmer is in a fantastic position to continue its growth in the sector. We’re proud to have delivered over 2,800 retrofit measures in the past year, and to be supporting 18 local authorities in delivering high-quality retrofits to make homes in their areas more comfortable and more affordable to run.”

Mullan, who began his career in social housing and public procurement, gained significant experience in ECO-funded retrofits from 2013–2019, working his way up from Commercial Manager to Managing Director at a previous retrofit business before founding Warmer Energy Solutions.

Simon Bettley, Commercial Director, added: “From humble beginnings in 2020, we’ve pursued our vision to lead the way toward a future where every home is powered by clean, renewable energy. We envision a world where energy efficiency is the standard, and sustainability is at the heart of every decision. Through innovation, education, and a commitment to excellence, we aim to combat fuel poverty in the UK.

We’re doing this by providing innovative, sustainable, and cost-effective renewable energy solutions that help private householders, social housing providers and local authorities to reduce the energy bills and lower the carbon footprint of their properties.”

As Warmer Energy Solutions enters its next chapter, the company is looking to expand its role as a leading provider in the retrofit sector by leveraging appointments across a number of national and regional frameworks, including the GMCA Net Zero Housing Retrofit Framework, that allow landlords to access their technical delivery expertise, compliance assurance and tenant-focused care with ease.

Very professional

Warmer energy are a very professional and knowledgeable company. We recently had our property insulated new heat pump radiators and solar panels installed. We are so happy with the results, the time taken and the very professional trades contracted for the job. From first speaking with Tom, Bethany and Laura...they kept me informed and very professionally talked me through the whole process to finishing up with Solomon who sorted few small issues (ie. Cornice, carpets, light sockets etc) who sorted everything. Honestly we are so delighted with the work done and massive thanks to warmer energy and the team.Read More

I can’t recommend Warmer highly enough

Absolutely Outstanding Solar Installation – Highly Recommended!
From start to finish, the service from Warmer Energy has been exceptional. We had a 58-panel Solar PV system installed along with a 20kW battery storage solution, and the whole process was seamless.
The initial survey was carried out by a very experienced and...knowledgeable surveyor who took the time to explain everything clearly and tailored the system to suit our needs. No hard sell – just honest, helpful advice.
The installation team was brilliant – professional, tidy, and knowledgable. They worked efficiently and kept us informed every step of the way.
Customer service has been spot on throughout. From arranging DNO approvals to helping us register for SEG, they handled everything with minimal hassle for us. Any questions we had were answered quickly and clearly.
We’re already seeing fantastic performance from the system and having the 20kW battery has given us huge flexibility and peace of mind around energy usage and costs for our business.
If you’re thinking about going solar, I can’t recommend Warmer highly enough. Great people, great products, and truly excellent service.
Thank you to the whole team!

Brilliant from day one

Improvements carried out to improve the energy rating of the property. Brilliant from day one. Installations completed by three days as they planned. these will make a massive difference over the winter and hopefully keep the many chest infections at bay. Everyone of their team was helpful from day one,...phone calls, visits and during the installation process. To be honest I can't thank them enough as I know this will make a massive difference to my health. Thanks again

Couldn't have wanted a better experience.

From start to finish, I have had many chances to see a professional company at work. Communication was spot on, calls and emails to update me at every step of the way. The attention to detail in the survey was pretty eye opening and took the lad a...long time to get all the information they needed. They arranged the power supply upgrade with the the power company and the day it was commissioned, they had dates in place to do the air source heat pump, panels and insulation's. The installers were knowledgeable , professional and nice. Felt at ease and safe knowing they were on top of it all, Brian and Chris were exemplary. (Maybe not the best singers, but at least their radio station choice was good). Every thought, adaption and problem solving moment was fully discussed, explained and implemented by these guys. Couldn't have wanted a better experience. Good on them, you won't go wrong using these guys.Read More

We had an air source heat pump system installed. The fitters worked in freezing weather to get our system up and running as soon as possible. They were polite and friendly. I would without a doubt recommend this company to anyone.
