Radiator Installation

About our radiator installation service

Reliable heating relies on more than just a powerful boiler. The radiators in your property are the final point of delivery for warmth, and leur correct placement and sizing are essential for comfort. At Design N Build, we provide comprehensive radiator installation services for residential homes, refurbished apartments, and commercial office blocks. Whether you are looking to replace dated, inefficient panel radiators with modern designer models or need to relocate emitters during a kitchen extension, our Gas Safe registered engineers ensure the work is carried out to high technical standards. We often integrate these works with wider Central Heating Installation projects or as a supplement to Underfloor Heating in multi-storey builds. Our service covers everything from the initial BTU (British Thermal Unit) calculations to the final system balancing, ensuring that your heating system operates at peak efficiency without cold spots or noisy pipework. From standard compact radiators to bespoke vertical columns and towel rails, we manage the full mechanical setup including thermostatic valve fitting and pipework alterations.

What's included

• Designer Radiator Fitting

  We install a wide range of designer, column, and vertical radiators that serve as a focal point while providing efficient heat.

• Thermostatic Valve Installation

  Upgrading old manual valves to modern Thermostatic Radiator Valves (TRVs) allows for individual room temperature control, saving money on energy bills.

• Radiator Relocation and Re-piping

  If you are removing walls or changing room layouts, we can professionally reroute your central heating pipework to relocate radiators to more suitable positions.

• Full System Power Balancing

  A critical service to ensure that radiators furthest from the boiler receive enough hot water to heat up at the same rate as the rest of the building.

• Safety Radiator Solutions

  Specialised installation of LST radiators in care homes, schools, or nurseries to prevent accidental burns while maintaining high heat output.

Key benefits

• Improved Thermal Efficiency

  Correct radiator sizing ensures every room reaches a comfortable temperature without the boiler working harder than it needs to, reducing unnecessary energy consumption.

• Accurate Heat Loss Calculations

  Our engineers calculate heat loss for each room to ensure your new radiators provide sufficient warmth even during the coldest winter months.

• Balanced Heating Distribution

  We perform full system balancing after installation, ensuring hot water is distributed evenly so that no room remains colder than the others.

• Protection Against Leaks

  Professional installation removes the risks of slow leaks or air pockets that can cause internal corrosion and damage your floor coverings or walls.

• High Quality Aesthetic Finish

  Whether choosing modern designer columns or traditional panels, a professional fit ensures perfectly straight mounting and discreet pipework that enhances your interior design.

Project types we cover

Our process

1. 1
   Room Heat Loss Assessment

   We calculate the BTU requirements for each room based on dimensions, window sizes, and insulation levels to ensure the correct radiator size is selected.

2. 2
   System Drain and Mounting

   The heating system is safely drained down. We then install the new brackets and mount the radiators, ensuring they are perfectly level and secure.

3. 3
   Pipework Configuration

   Our engineers modify or extend copper or plastic pipework to meet the new radiator positions, ensuring all joints are soldered or pressed securely.

4. 4
   Refill and Chemical Treatment

   We refill the system, adding high quality chemical inhibitor to prevent internal corrosion, and thoroughly bleed every radiator to remove air.

5. 5
   System Balancing and Testing

   The final stage involves adjusting the lockshield valves on every radiator to ensure the heated water is distributed correctly throughout the property.
