Efficient Heat Pump & Water System Solutions
Reliable air-source, ground-source and chilled water systems designed for comfort, performance and long-term energy efficiency.
Renewable Heating
& Cooling Engineered for the Future
At SJB Mechanical & Building Services Ltd our team design, install and maintain heat pump and water-system solutions that deliver year-round comfort and exceptional efficiency. Based in Brentwood, Essex we serve domestic and commercial clients across the South East with accredited engineering and professional service.
Air Source
Heat Pumps
Our air-source systems extract heat from ambient air to provide hot water and central heating even in colder months. This renewable choice helps reduce carbon emissions, energy bills and offers a future-proof alternative to conventional fossil fuel systems.
We are approved installers and MCS accredited engineers, ensuring compliance with industry standards and eligibility for government incentives.
We deliver bespoke solutions across domestic, commercial and multi-occupancy projects, using leading brands such as Samsung, Daikin and Mitsubishi.
Typical savings and performance figures are provided during a free consultation, helping you understand the return on investment.
Ground Source
Heat Pumps
Ground-source heat pump systems exploit stable sub-surface temperatures and offer some of the most efficient heating and cooling solutions available. These systems are particularly suited for new builds, large plots or commercial applications where ground loop installation is feasible.
With SJB Mechanical’s engineering expertise we deliver full design, installation and commissioning of ground-source solutions tailored to your building.
Chilled
Water Systems
For large buildings and specialist sites where traditional air-conditioning may be limited or cost-prohibitive, chilled water cooling systems offer a powerful and efficient alternative.
These systems circulate cold water through a pipe network, enabling extended reach (up to 400 m) while avoiding the use of refrigerant-based air-conditioning systems. Benefits include reduced noise levels, enhanced safety and lower running costs—ideal for commercial premises, large-scale developments and high-end applications.
