What is a new house?

Building regulations and compliance

New-build homes in the UK must comply with Building Regulations. These regulations set clear standards for safety, energy efficiency, ventilation, accessibility and structural strength. The overall aim of Building Regulations is consistent across the UK, but the specific standards and guidance may differ from one nation to another.

During construction, new homes are typically inspected and assessed at key stages to ensure that standards are being met.

Modern construction methods and materials

Housebuilders select materials and construction methods that meet industry standards at the time of build and their own specifications. This ensures each stage of the build adheres to essential safety and performance requirements.

The specific approach and materials used can vary by housebuilder and development, but these standards guide the process from initial structural work to the final finishes.

Design features and layouts

There is no single architectural style used across all new houses, but many share a focus on simplicity, ease of maintenance and multipurpose rooms. They typically include features shaped by modern living, such as:

• Practical designs that maximise natural light

• Open-plan kitchen and living areas

• Multiple bathrooms or en suites

• Efficient use of interior space, including integrated storage

• Flexible rooms that can adapt to changing needs, such as home working or family life

Energy efficiency

UK Building Regulations set by the government require new builds to meet minimum energy-efficiency standards. As a result, many new-build homes are designed with energy performance in mind and may include the following features:

• Enhanced insulation

• Double-glazed windows

• Efficient heating systems

• Construction methods designed to limit heat loss

These features mean new-build homes may contribute to lower running costs, though this depends on factors such as occupancy, heating patterns and energy prices. According to HBF data (January 2026), a brand-new home could be up to 21% more energy efficient than an older home, meaning you could save up to £420 per year on your running costs†.

Warranties and protections

New-build homes often come with a warranty and insurance policy, such as the NHBC Buildmark warranty. This can help provide protection against certain defects for a set period. Coverage levels, terms and providers can vary, so you may want to review individual policy documents to understand what each policy covers and how to make a claim.

Some new-build homes may also be covered by the New Homes Quality Code, overseen by the New Homes Quality Board. This code of practice sets standards for customer service, building quality, safety and aftercare, requiring registered housebuilders to meet defined requirements throughout the homebuying process.

Additional features

Specifications vary between housebuilders, but some developers may offer additional features, such as:

• Integrated kitchen appliances

• Options for flooring upgrades

• Underfloor heating

• High-speed fibre broadband (FTTP)

• Electric vehicle charging point options

These features aren't guaranteed across every housebuilder, so check your developer's additional features before committing.
