Electrical Lifecycle Testing
Stop replacing electrical infrastructure on a guess
Most switchgear is condemned on its age, by surveys that never open the panel. We test what’s actually inside, so you only replace what needs replacing.
The problem
Age is a poor guide to condition
Standard surveys look at the outside of a panel, check its age against a table and give it a replacement year. That is how a sound electrical system ends up with a seven-figure replacement programme.

Ofgem, CIBSE, BEAMA and the HSE all say age alone is not a reason to replace
When you need this
Three common starting points
A survey recommended a big replacement
You have a report that dates your switchgear for replacement, and a large bill attached to it.
You’re about to electrify
Heat pumps and EV chargers depend on the electrical kit you already have. You need to know it can take the load.
You’re buying a building
Due diligence needs the true condition of the HV and LV equipment, not an age-based guess.
The difference
We open the panel. Standard surveys don't
The principle: replace on condition, not age. CIBSE Guide M’s life tables are indicative, and Ofgem, CIBSE, BEAMA and the HSE all say age alone is not a basis for replacement.
Our Process
Four steps from records to remedials
1
Asset data review
We find out what records exist and what they tell us.
2
On-site intrusive testing
Our electrical engineers open, measure and record LV and HV equipment on site.
Planned outages, scheduled out of hours and agreed with your tenants.

Every intervention is given a priority:

Replace on evidence
The gap between the guide table and reality is where the money is
Guide tables give an indicative economic life. Real equipment, tested and maintained, often lasts far longer.
