Service Warranty and Call-Out Charges
The information below provides clear details on our warranty terms and call-out charges, including what is covered, how our support services operate, and any applicable costs.

If a fault occurs during the warranty period, replacement parts will be supplied free of charge; however, the standard call-out fee will still apply.
Once the warranty period has expired, any replacement parts will be charged at cost.
The warranty will be void if any damage or faults are caused by misuse, accidents, general wear and tear, tampering, unauthorised modifications, or third-party interference.

The following warranty periods apply to the products we supply and install:
Ajax: 2 Years
Toshiba: 3 Years
Seagate: 3 Years
Western Digital: 3 Years
Additional Information
All hardware is sourced directly from authorised UK Ajax distributors, ensuring authenticity, reliability, and full manufacturer warranty support.
Standard Call-Out Fee
For existing customers within our standard service area (Leeds and West Yorkshire), the call-out charge starts from £95.00. This includes travel, attendance, system assessment, fault finding, testing, and minor adjustments or basic troubleshooting carried out during the visit.
Please note that some faults or underlying issues may only become apparent once an on-site inspection has been carried out. If additional time, labour, or replacement parts are required to diagnose or resolve the issue, this will always be discussed and agreed before any further work is undertaken.
Out-of-Area Call-Out Fee
For customers located outside our standard Leeds and West Yorkshire service area, call-out charges start from £199.99. This fee covers travel, attendance, fault finding, and assessment.
Additional charges may apply depending on distance, time spent on site, and any further work required.
As with all call-outs, some faults or underlying issues may only become apparent once an on-site inspection has been carried out. If additional time, labour, or replacement parts are required to diagnose or resolve the issue, this will always be discussed and agreed before any further work is undertaken.
Call-Out Booking Fee
All call-out visits must be booked and paid for in advance.
The call-out booking fee starts from £95.00 for customers within our standard service area (Leeds and West Yorkshire) and from £199.99 for customers outside our standard service area. This fee secures your appointment date and time and covers attendance, travel, fault finding, system testing, and diagnosis.
Please note that the call-out fee covers the visit and investigation only. Additional labour, replacement parts, or further works will be quoted separately if required.

Important Notice
Customers must not attempt to open, modify, or replace batteries in Ajax devices themselves or through third parties. Doing so will void the warranty and may cause damage, faults, or system malfunction.
