Are Your Electrics Due A Safety Check?
One rental flat or a portfolio of them, no job is too big or too small for our electricians.

Cardiff based, so we can group several properties into the same week and cut the travel.

Landlord Electrical Testing In Wales
Meeting Your Renting Homes Act Obligations
Renting out in Wales is not the same as renting out in England, and the difference catches out people who own property on either side of the border.
Under the Renting Homes (Wales) Act, the electrical installation in a rented property must be inspected and tested at least every 5 years by a qualified person, and the tenant has to be given a copy of the report. That sits alongside your Rent Smart Wales registration, whether you manage the property yourself or through an agent.
What we see going wrong is rarely the wiring, it is the paperwork. A report that exists but never reached the tenant, or remedial work done with nothing in writing to prove it. Where C1 or C2 faults are found, we explain them, price the work separately, and issue an updated EICR once it is resolved.
Rules change, so check the current position with Rent Smart Wales if anything looks borderline.
What Your Report Tells You
Fault Codes & What You Must Act On
Testing is part inspection and part measurement, and the inspection finds more than people expect. Scorch marks, undersized cable and a shower fed off a lighting circuit all turn up by eye before an instrument comes out of the case.
The measured tests cover continuity of protective conductors, insulation resistance, earth fault loop impedance, polarity and RCD trip times against the limits they have to meet. In an occupied property, that means the power is turned off in stages, which we tell you about beforehand.
Every observation is coded. C1 means danger present, and we make it safe before leaving. C2 means potentially dangerous, and it has to be put right. C3 is improvement recommended and does not fail the report. FI means further investigation is needed.
The gap between C2 and C3 is where landlords get caught out, so we talk you through which is which. Any work you want us to carry out is handled by our electrical repairs team.
Frequently Asked Questions
Our Electrical Testing FAQs
How often does a property need electrical testing?
Rented properties in Wales need testing at least every 5 years, with a copy given to the tenant. Owner-occupied homes are generally tested every 10 years, and commercial premises every 5 years.
What does electrical testing cost?
It varies with the size of the property, the number of circuits and how accessible the installation is. A one-bedroom flat and a four-bedroom house are different jobs, so we price each one properly.
Will my power be off while you test?
In stages rather than all day, because some tests cannot be done live. On a typical house, it is a couple of hours. Tell us if anything cannot lose power.
What happens if my property fails?
An unsatisfactory report means at least one C1 or C2 item needs putting right. Anything dangerous we make safe before leaving, and the remedial work is quoted separately.
