Gas Condensing Boilers
At Nexcusecobuilt, we are committed to helping customers cut their energy bills, reduce costs, and minimise environmental impact. The UK offers excellent opportunities for homeowners in fuel poverty to access energy funding, with support from energy suppliers, the government, and local councils.
What Are the Benefits of Upgrading to a New Boiler?
Most modern condensing boilers are A-rated and can offer up to 90% fuel efficiency. Installing a new boiler means your home will use less energy, helping to significantly cut your heating costs. According to the Energy Saving Trust, central heating accounts for around 60% of a household’s energy use — so upgrading your boiler can make a big difference to your overall energy expenses.
The advantages of a new boiler upgrade include:
- Lower energy bills
- Improved heating efficiency
- A cosier, more comfortable home
- Added value to your property
- Quieter, more reliable performance
Efficient, Eco-Friendly Heating with Modern Gas Condensing Boilers
Gas condensing boilers offer more than just reliable heating — they’re designed to improve your home’s energy efficiency, lower carbon emissions, and help reduce your energy bills. The best boiler choice depends on your property’s size, insulation, and heating needs.
At Nexcusecobuilt, our experts will assess your home and recommend the most suitable condensing boiler system for optimal performance. We supply and install high-quality, energy-efficient boilers that comply with UK standards, providing long-term warmth, comfort, and cost savings.
How much could I save by upgrading to a new boiler?

Installing an A-rated boiler in your home could help you cut hundreds of pounds from your annual energy bills.
At Nexcusecobuilt, we’re dedicated to lowering our customers’ energy costs while supporting meaningful environmental progress.
With energy prices continuing to rise in recent years, upgrading your old boiler is a smart way to reduce expenses and make your home more efficient.
You might qualify for a brand-new A-rated boiler installed at no cost to you. Various funding schemes exist to support boiler replacements, and we’ll guide you through every step. If you receive a qualifying benefit and your boiler is over 10 years old, you could be eligible for a fully funded boiler installation under the UK government’s ECO scheme.
