About Us Test Instrument Solutions

With 72 years of combined industry experience, we have expanded our portfolio to include Power Quality analysis equipment and Solar PV testing instruments. In 2020, we launched one of the most advanced EVSE charging station testing & reporting systems available.

In 2009, we introduced our Calibration division, delivering expert calibration services at competitive prices for all manufacturers’ equipment. We hold ISO9001 accreditation, ensuring high standards in multifunction testers (MFT testers), thermal imaging calibration, environmental instruments, and torque wrenches & screwdrivers.

We also offer on-site Calibration Days at electrical wholesalers, providing instant certificates at special rates. For customers with multiple testers, we can visit their site, minimising downtime while processing transactions through their wholesaler account.

    Delivery Policy
    Free Next-Day Delivery Over £75 + VAT:
    Orders above £75 + VAT qualify for free next-day delivery via DPD for in-stock items. While we strive for timely dispatch, we recommend placing orders early to avoid potential delays. Once dispatched, unexpected issues may arise despite the courier’s efforts.

    Orders Below £150 + VAT:
    To keep costs manageable, we dispatch your order once all items are ready, including products with longer lead times.

    Need items faster? You can pay for an additional delivery service to receive in-stock items sooner. Simply email us with your order details, and we’ll send you a payment link for the extra delivery cost.

    Orders Above £150 + VAT:
    For larger orders, we can split delivery at no extra cost. In-stock items will be sent immediately, with the remaining items dispatched once available.
    Dispatch Times
    Items with Lead Times (e.g., 1–3 Working Days):
    This means we need to source the product from our supplier before sending it to you. The estimated dispatch time is displayed on each product page.

    Out of Stock at Supplier:
    If an item is unavailable at the supplier, we will contact you promptly. You’ll have the option to choose an alternative product or request a full refund.
