Heating & Plumbing

Accredited Commercial Heating & Plumbing Specialists in London

With more than 25 years of experience, Brit Heating has become a trusted provider of advanced Heating & Plumbing solutions for commercial buildings, large residential developments, hotels, care homes, offices and mixed-use properties across London. As part of Omega Group, we offer fully certified, engineered and integrated Mechanical, Electrical and Plumbing services designed for performance, safety and long-term reliability.

We specialise in commercial boiler systems, plant room design and refurbishment, high-demand hot water production, pressurised heating systems, large-scale plumbing installations and full commercial mechanical upgrades. Our engineers are accredited installers for leading domestic and commercial boiler manufacturers, enabling us to provide extended warranties, enhanced system performance and fully compliant installations that meet industry regulations and manufacturer standards.

Our domestic division continues to support homeowners, landlords and residential developments; however, our primary expertise lies in commercial heating and large-scale MEP infrastructure. This includes full plant room replacement, commercial boiler cascade systems, industrial pipework distribution, plate heat exchangers, pressurisation units, underfloor heating, boosted cold-water systems, drainage networks and mechanical hot water generation. Every system we install or upgrade is engineered for safety, efficiency and longevity.

Commercial Heating & Boiler Systems

Commercial heating forms the core of our operations. We design, install, service and maintain commercial gas boilers, cascade boiler arrangements, commercial heat exchangers and industrial heating plant rooms for a wide range of buildings including hotels, hospitals, schools, care homes, office blocks, warehouses and high-rise apartment buildings. Our engineers are fully trained and certified to work on commercial gas systems, ensuring complete compliance with Gas Safe regulations.

As accredited installers for Hamworthy Heating, Lochinvar, Rinnai, Andrews Water Heaters, Ideal Commercial, Vaillant Commercial, Remeha and other leading manufacturers, we are able to provide correctly engineered commercial boiler solutions with manufacturer-backed guarantees from 6–10 years. Whether a property requires a full plant room refurbishment, a commercial boiler replacement, increased heating capacity or the integration of renewable systems such as ASHP, we deliver solutions that match the heating load, building size and operational requirements.

Our plant room services include the removal of outdated systems, redesign of mechanical layouts, installation of new boilers and hot water equipment, rewiring and mechanical controls, pump sets, buffer vessels, expansion systems, valves, flues and BMS integration. Every commercial plant room we deliver is fully commissioned, tested and documented for safe handover and operation.

Commercial Hot Water & Pressurised Systems

Brit Heating is highly experienced in delivering high-recovery commercial hot water systems for buildings with significant daily demand. We install pressurised calorifiers, unvented commercial cylinders, plate heat exchanger hot water systems, secondary return pipework, pressurisation units and commercial hot water booster pumps.

Hotels, care homes and multi-unit buildings rely on us to design and deliver systems capable of supplying continuous hot water at stable temperatures and pressures. We ensure every installation is engineered to withstand peak demand periods while maintaining efficiency and compliance with building regulations.

Heating System Upgrades, Mechanical Components & Controls

Brit Heating also specialises in heating system optimisation and mechanical upgrades. We replace outdated radiators, pumps, valves and controls, convert open-vented systems into sealed, pressurised systems, and provide full system balancing and commissioning for improved performance.
Our mechanical component services include the installation of circulation pumps, diverter valves, zone valves, bypass valves, expansion vessels, automatic air vents, strainers, filters and magnetic DirtMag systems — all essential for maintaining clean, efficient and trouble-free heating and hot water networks.

Smart controls and commercial BMS integration form an important part of our offering. These solutions help clients improve efficiency, reduce energy consumption and maintain more accurate control over heating and hot water systems.

Underfloor Heating Solutions (UFH)

We install large-scale underfloor heating systems for commercial and residential developments, providing detailed pipe layouts, manifold zoning, system integration and full commissioning. Underfloor heating is fully compatible with ASHP systems, commercial boilers and hybrid systems, making it an increasingly popular and efficient heating solution for modern developments.

Renewable Heating – Air Source Heat Pumps

Air Source Heat Pumps are a growing part of the heating landscape, and we offer complete ASHP solutions including heat-loss calculations, system design, specialist cylinders, hybrid heating setups and integration with MVHR or UFH systems. Our engineers are trained to install and commission renewable heating systems safely and efficiently, offering reliable alternatives to gas and traditional hot water systems.
