Types of Renewable Energy Systems for New Builds

There are several renewable energy systems suitable for new build homes in the UK. Below, we explore three of the most popular options: solar photovoltaic (PV) panels, heat pumps, and solar thermal systems.

Solar Photovoltaic (PV) Panels

Solar PV panels are among the most common renewable energy systems for new builds in the UK. These panels convert sunlight into electricity, which can then be used to power household appliances and lighting. By producing electricity on-site, homeowners can reduce their dependency on the grid and lower energy costs. Solar PV is especially effective in new builds, as they can be designed and oriented for optimal sunlight exposure.

Air-Source and Ground-Source Heat Pumps

Heat pumps are highly efficient systems that extract heat from the air or ground, even at low temperatures, to provide heating and hot water. Air-source heat pumps are generally more affordable and easier to install, while ground-source heat pumps offer higher efficiency and greater long-term savings, although they require more extensive groundwork. Heat pumps are increasingly popular in new builds, as they can be integrated into the design of the home to improve heating efficiency and lower energy bills.

Solar Thermal Systems

Solar thermal systems use sunlight to heat water directly, making them an ideal choice for homes with high hot water demand. Solar thermal systems are efficient, can reduce water heating costs, and are easier to incorporate into new builds where they can be optimally oriented for sunlight. This makes them a popular option for homeowners looking to further cut down energy costs associated with heating water.

Cost Implications of Renewable Systems for New Builds

Although renewable energy systems require an initial investment, installing them during the construction phase of new builds can be more cost-effective than retrofitting later. By considering renewable systems early in the design and construction process, homeowners and developers can save on installation costs and minimise future energy expenses.

Solar Panel Installation Costs

The cost of installing solar PV panels on a new build home typically ranges from £4,000 to £6,000 for a standard 4 kW system. The final cost can vary based on factors like roof size, panel quality, and labour expenses. In many cases, new builds can be designed with solar in mind, reducing potential installation costs and maximising energy production.

Heat Pump Installation Costs

Air-source heat pumps generally cost between £7,000 and £13,000 for a typical home, while ground-source heat pumps can range from £15,000 to £25,000. These systems are highly efficient, reducing energy costs associated with heating and hot water. By including heat pumps in new builds, the construction can be optimised to suit these systems, potentially reducing installation costs and improving heating performance.

Government Incentives for Renewable Energy in New Builds

To make renewable energy more accessible, the UK government offers several incentives for homeowners to help offset the installation costs of renewable systems.

Boiler Upgrade Scheme

The Boiler Upgrade Scheme provides grants for installing renewable heating systems, such as heat pumps. Under this scheme, homeowners can receive a grant of £5,000 for air-source heat pumps and £6,000 for ground-source heat pumps, significantly lowering the cost of installation. This scheme supports the shift toward renewable heating solutions in residential properties.

Smart Export Guarantee (SEG)

The Smart Export Guarantee (SEG) allows homeowners with solar PV systems to sell surplus electricity back to the National Grid. This can provide an additional income stream, making solar PV a more attractive option for new builds. Rates vary by energy provider, so it’s important to compare tariffs to maximise SEG earnings.

Planning and Regulatory Considerations

Integrating renewable energy systems in new builds involves specific planning and regulatory considerations. These systems need to meet building codes and energy efficiency standards to ensure safety, performance, and compliance with local regulations.

UK Building Regulations for Energy Efficiency

Building regulations in the UK mandate energy efficiency standards for new builds, which support the installation of renewable energy systems. The latest Part L regulations set high energy performance standards, encouraging the use of renewable energy to reduce carbon emissions in new homes.

Permitted Development Rights for Solar Panels

In most cases, solar panels fall under permitted development rights, which means they can be installed without requiring planning permission. This simplifies the process for developers and homeowners looking to incorporate solar energy into new builds. However, listed properties or those in conservation areas may require additional permissions.

Long-Term Savings and Financial Benefits

While renewable systems require initial investment, the long-term savings from reduced energy bills and lower maintenance costs make them financially attractive. Below is an overview of potential savings for solar PV and heat pumps.

Potential Savings with Solar PV

Solar panels can save UK homeowners between £150 and £400 annually on electricity bills, depending on system size and household energy usage. Battery storage can increase these savings by allowing homeowners to store excess energy for use during high-demand hours. Over a system’s lifespan, these savings can add up to thousands of pounds.

Heating Savings with Heat Pumps

Heat pumps provide efficient heating at a lower cost than traditional systems, with air-source heat pumps potentially reducing heating bills by up to 50%. Ground-source heat pumps may offer even greater savings, especially in colder regions where they are particularly effective. For an average UK home, this translates to savings of £500 to £1,000 per year.
