Air Source Heat Pumps (ASHP)
We install and commission air source heat pump systems with the expertise of our team, including an MCS-qualified engineer based in Kent, delivering reliable solutions for commercial and multi-unit properties. ASHPs provide significantly better heat output per unit of energy than traditional boilers, making them a cornerstone of energy efficiency retrofits.
Unvented Cylinders
For hot water delivery in retrofit refurbishments or new builds, we supply and replace unvented cylinders to ensure efficient, reliable and instant hot water across multiple units.
Gas Systems
Our Gas-Safe registered engineers manage servicing, safety checks, repairs and upgrades, ideal if part of the building remains on gas or requires hybrid systems during retrofit phasing.
Leak Detection & Water Repairs
We offer rapid detection and remediation to prevent water loss and potential damage, an essential maintenance service for commercial sites.
Booster Pumps
For large, multi‑occupancy buildings or those with pressure issues, we install and maintain booster pump systems for consistent water pressure and reliability.
Maintenance Services
Whether you need reactive repairs or a scheduled maintenance contract, we support long-term upkeep of plumbing and heating systems, crucial for sustaining the benefits of energy efficient retrofits and renewable heating systems over time.
