Dedicated in-house service departmentProtecting your investment for the long term
Our dedicated, in-house service department provides monitoring, maintenance and support for the lifetime of your system — whether we installed it or not.
What we service
From a single domestic water borehole to a multi-megawatt commercial GSHP array, our service team has the expertise and equipment to keep your system performing.
Borehole Servicing
Pump testing, water quality sampling, headworks inspection and soakaway performance monitoring. Keep your water supply reliable and compliant.

Most maintenance providers only cover part of your system. At Nicholls, our drilling and engineering background means we understand the complete picture — from the aquifer to your taps.
We service systems installed by others
You don't need to be an existing Nicholls client. We're happy to survey and take on the maintenance of systems installed by other contractors.
Dedicated in-house team
Our service department is not outsourced or sub-contracted. Dedicated engineers with their own fleet of service vehicles.
Complete system coverage
Unlike standard heat pump engineers, we cover everything from borehole to plant room to distribution. One team, one point of contact.
Bespoke maintenance programmes
Every system is different. We tailor the maintenance schedule to your system size, source water quality and usage pattern.
Remote monitoring
Off-site monitoring of your system, with alerts for performance issues before they become failures.
Specialist knowledge
Our engineers understand the subsurface — boreholes, ground loops, aquifer behaviour — not just the mechanical plant above ground.
Flexible service options
We tailor our service to your needs — from a one-off inspection to a comprehensive ongoing maintenance contract.
Annual Service Visit
Scheduled inspection, testing and basic maintenance to keep your system running efficiently.
Maintenance Contract
Comprehensive programme with regular visits, priority response and planned component replacement.
Monitoring & Support
Remote off-site monitoring with alerts, combined with annual on-site inspection.
Emergency Callout
Responsive callout for pump failures, system breakdowns and urgent issues.
All service options are tailored to your specific system. Contact us to discuss a proposal.
System installed by someone else?
