Underfloor Heating
Efficient and invisible heating solutions for homes and businesses through professional wet and electric underfloor installations.
About our underfloor heating service
Underfloor heating has moved from a luxury addition to a practical standard for modern UK properties. Design N Build provides comprehensive installation services for both residential homes and commercial spaces, ensuring your property benefits from consistent, radiant warmth. Unlike traditional radiators that take up valuable wall space and often leave cold zones, underfloor systems turn the entire floor into a low-temperature radiator. We support homeowners during kitchen and bathroom refurbishments and assist developers during the first-fix stage of new builds. Our expertise covers the full spectrum of the technology, from hydronic (wet) systems that integrate with your Boiler Installation to thin-profile electric mats perfect for retrofitting into older buildings. By focusing on precision engineering and high-quality insulation, we ensure every system we install operates at peak efficiency while lowering your property's carbon footprint. Whether you are looking for a standalone solution or integration with wider Smart Heating Systems, our team manages the entire process from structural assessment to the final handover.
What's included
- Hydronic (Wet) Systems
Installation of pipework and manifolds connected to your central heating. This is often the most cost-effective solution for large-scale residential and commercial heating.
- Electric Underfloor Heating
Ideal for smaller areas and retrofits, these cable and mat systems provide quick heat-up times without significantly raising the floor height.
- Smart Control Integration
Integration of thermostats and zone controls that allow you to manage the temperature of every room individually through your smartphone or hub.
- Flooring Compatibility Advice
Expert advice on the best floor coverings to use with your system, ensuring maximum thermal conductivity and protecting your floors from heat damage.
- Manifold Installation and Testing
Professional installation of the distribution hubs that regulate the flow of warm water to different zones of your property for precise temperature control.
Key benefits
- Increased Energy Efficiency
By distributing heat evenly across the entire floor surface, these systems eliminate cold spots and reduce the energy needed to maintain a comfortable room temperature.
- Architectural Flexibility
Removing the need for traditional radiators allows for complete freedom when choosing furniture layouts and simplifies interior design in both modern and period properties.
- Superior Thermal Comfort
Operating at lower temperatures than radiators, underfloor systems provide a gentle, consistent warmth that feels more natural and prevents the dry air often associated with convection heating.
- Improved Air Quality
Underfloor heating reduces dust circulation and mites by keeping floors dry and limiting air movement, making it a healthier choice for residents with allergies or respiratory issues.
- Multi-Surface Compatibility
Whether you prefer luxury vinyl tiles, engineered wood, or traditional stone, modern heating systems are compatible with almost any finish when installed with the correct subfloor preparation.
Project types we cover

Our process
- 1Site Assessment and Planning
We evaluate your floor structure, heat loss requirements, and the best system type for your specific needs, whether that is a screed-based or overlay solution.
- 2Subfloor Preparation
Proper insulation is laid to ensure heat is directed upwards into the room rather than lost into the ground, a critical step for system efficiency.
- 3System Laying and Connection
Our engineers lay the pipework or electric mats in a precise pattern to ensure even heat distribution, connecting them to the manifold or electrical supply.
- 4Pressure Testing and Safety Checks
Before any flooring is laid, the system is pressure tested to check for leaks and ensure the electrical circuits are fully functional and safe.
- 5Commissioning and Handover
We integrate the system with your thermostats and provide a full demonstration on how to manage your new heating for maximum comfort and economy.

Our focus is on creating systems that lower your energy bills and minimize environmental impact through better thermal efficiency.
Frequently asked questions
How long does the installation process take?
Installation timelines vary based on the system type. An electric mat system in a small bathroom can often be completed in a single day. However, a full-screed wet system for a house renovation typically takes 3 to 5 days for the pipework and manifold installation, followed by the necessary curing time for the floor screed.
Can underfloor heating be installed in an existing home?
Yes, we specialise in retrofit solutions. For existing buildings where floor height is a concern, we use low-profile overlay systems. These allow the heating pipes to be laid over the existing subfloor with minimal impact on door heights and skirting boards, avoiding the need to dig up concrete floors.
What is the difference between wet and electric systems?
Wet systems use hot water from a boiler or heat pump and are highly cost-effective for large areas or whole-house heating. Electric systems use heating cables or mats and are generally cheaper to install but more expensive to run, making them ideal for smaller zones like bathrooms or kitchens.
Is underfloor heating expensive to run and install?
The cost depends on the floor area, the chosen system, and the complexity of the manifold connection. While the initial investment is higher than traditional radiators, the long-term energy savings and added property value often offset the upfront costs. We provide fixed-price quotes after a site assessment.
What kind of maintenance is required?
Most systems require very little maintenance. For wet systems, we recommend occasional checks of the manifold pumps and valves, similar to a standard Central Heating Installation. The pipes themselves are designed to be durable and often come with 25-year to 50-year manufacturer guarantees.
