Very professional, very high quality of work, effective communication throughout. Every builder or tradesman we’ve had since we’ve had our render done by Infinity has commented on how good it looks and they can tell it’s high quality. During the works they were very careful not to damage our new windows and even came with their own portaloos! Would definitely recommend them

I have recently had my two-storey Victorian terraced house done on the external and partial internal wall insulation by the Infinity Energy Organisation. It is a mixed commercial and residential property so the arrangements of the survey and the building works were complicated.

Harshit, who conducted the building survey, had worked hard with great patience to find solutions to keep all parties satisfied.

The work started and finished as promised in 3 weeks. They arrived on time every day, and kept working tirelessly till the end. They always laid down protection sheets on floors. There were insulation team, electrical team, and people at the office to coordinate, making sure the project went seamlessly. There were small issues after completing the job, but with communication, the issues were fixed straight away.

I am very impressed with their good team spirit and efficiency. The result of the work is high quality. I have no hesitation to recommend this company to anyone who would like to improve their homes on energy.

Types of Boilers We Install in London

We provide expert guidance and installation across all boiler types that include:

These boilers are best for small and medium size homes or flats. Combi boilers provide instant hot water without the need for a storage tank. They save space, work efficiently, and are ideal for homes that use less water.

System Boilers

These boilers are designed for larger homes, as system boilers use a cylinder to store hot water, which makes them suitable for families with multiple bathrooms. They deliver strong water pressure and consistent heating.

Regular Boilers

These are also known as conventional boilers, and these are best suited to older properties in London that have traditional heating systems. These boilers require both a tank and a cylinder, making them ideal for households with high hot water needs.

Benefits of Installing a New Gas Boiler in London

Upgrading your old boiler offers you multiple benefits for both comfort and cost savings. Modern boilers can lower your energy bills and help you save money in the long run. They’re also eco-friendly and reduce your carbon footprint. A new boiler improves overall reliability and reduces the chances of unexpected repair costs.
