Professional Radiator Installation & Replacement

Whether you need to replace a leaking or inefficient old radiator, add a new radiator to extend your heating system to an additional room or space, or simply upgrade to a more stylish or higher-output radiator, Sherborne Utilities provides a prompt, professional installation service across Dorset, Somerset, Wiltshire, Hampshire and Devon.

Old radiators — particularly the original panel radiators installed in properties from the 1970s to 1990s — can lose efficiency over time through internal corrosion and sludge build-up, reducing both their heat output and their service life. Replacing these with new, correctly sized radiators can make a meaningful difference to the comfort and efficiency of your heating system.

We supply and install radiators in a wide range of styles and outputs to suit your property and interior design preferences. From traditional cast iron column radiators ideal for period properties, to modern low-surface-temperature radiators for families with young children, we can advise on and source the right radiator for each application.

When adding a new radiator to an existing heating system, we carry out a heat loss calculation for the room to ensure the new radiator is sized correctly — an undersized radiator will leave the room cold while an oversized one will cycle on and off frequently and may unbalance the rest of the system.

Why Replace or Add Radiators?

New radiators improve comfort, efficiency and the appearance of your home.

Improved Heat Output

Modern radiators deliver better heat output for their size, heat up faster and cool down more quickly — giving you more responsive, efficient room heating.

Range of Styles

From traditional column radiators to contemporary flat panel designs, we supply and install radiators to suit all interior styles and requirements.

Quick Installation

Most radiator replacements and new additions can be completed efficiently, with minimal disruption and only a brief period during which the heating system needs to be drained.

All System Types

We install radiators on open-vented gravity systems, sealed pressurised systems and combination boiler installations — whatever your heating system, we can add to it.

Our Radiator Installation Process

Simple, efficient radiator fitting with minimal disruption to your heating system and daily routine.

01

Selection & Sizing

We advise on the correct radiator size for each room based on the room dimensions, insulation standard and desired room temperature, ensuring adequate heat output.

02

System Drain-Down

The heating system is drained down to allow the new radiator to be installed. We take care to protect floor and wall surfaces during this process.

03

Installation

The new radiator is hung on wall brackets, pipe connections made with appropriate valves, and the system refilled, inhibitor added and re-pressurised or topped up as required.

04

Balancing & Test

The new radiator is balanced against the rest of the heating system to ensure even heat distribution throughout the property, and tested for any leaks.
