    System Down?
    Don't Replace. Repair.

    When critical systems fail and parts are unavailable, CircuitFix engineers work at component level to restore operation — at a fraction of replacement cost.

    • System down — production or building operations stopped
    • No spare parts available, manufacturer discontinued
    • OEM support has ended on legacy equipment
    • Replacement cost is four to five figures
    • Every hour of downtime is direct financial loss

    Why CircuitFix

    Repair Where Others Cannot

    We are not a swap-and-replace service. CircuitFix engineers work at component level — diagnosing and fixing the root cause, not masking it.

    Component-Level Repair

    We repair boards at component level — replacing what failed, not the whole assembly.

    Obsolete Equipment

    Manufacturer support ended? We source equivalent parts for discontinued systems.

    On-Site Capability

    Engineers travel to your facility across London and the South East.

    Priority Response

    Fast response for critical breakdowns. We understand the cost of downtime.

    Technical Reports

    Detailed documentation of every fault found, component replaced, and test result.

    90-Day Warranty

    All repairs backed by a 90-day parts and labour warranty.
