Electrical Lifecycle Testing
An accurate picture of the condition of the low voltage (LV) and high voltage (HV) power systems serving your building. Standard practice relies on non-intrusive surveys that typically recommend wholesale replacement on indicative age; we test the actual condition of the asset before any replacement decision is made.
Turnkey — one team, end to end
One accountable team from strategy to maintenance — maximum return, minimum CapEx.

The Difference
Intrusive testing compared with standard surveys
Non-intrusive (standard survey)
✕External, visual — enclosures stay closed
✕Grade assigned from age & appearance
✕Life-expectancy tables used raw, against publishers’ own instructions
✕Output: a replacement year — and often a seven-figure programme
TI intrusive lifecycle testing
✓Safe isolation — panels opened & dismantled
✓Measured: insulation, contact resistance, partial discharge, protection, oil/DGA
✓Grade based on actual condition & duty
✓Output: evidence, priorities, and remedials delivered by the same team
The principle: electrical infrastructure replaced based on advice from CIBSE Guide M — not based on age only. Ofgem, CIBSE, BEAMA and the HSE are all on record that age alone is not a basis for replacement.
Our Process
Our process
1
Asset data review
What records actually exist.
2
On-site intrusive testing
Compliance and testing carried out on site by electrical engineers — LV and HV. Open, measure, evidence.
3
Condition assessment report
Every intervention prioritised: critical / high / medium / low.
4
Remedial works
Delivered against agreed priorities — by the same team that tested.
The Numbers
Replace on evidence, not on age
| Asset | Indicative Life (Guide Tables) | Achievable with Testing |
|---|---|---|
| Transformer | 25–30 yrs | 60+ yrs |
| LV panels | 20–25 yrs | 35+ yrs |
| Switchgear | 25–30 yrs | 40+ yrs |
Guide-table figures are indicative — the publishers say so themselves. Reference: CIBSE Guide M, indicative economic life expectancy. BS 7671 Amendment 4 changeover deadline: October 2026.
Every decade of extended life defers seven-figure replacement CapEx.
One survey, two returns: avoided replacement CapEx today — verified headroom for electrification tomorrow. The gap between the guide table and the tested reality is where the money is; one intrusive survey tells you where your assets actually sit.
