Periodic Testing Specialists

Periodic Testing.
Inspected. Coded. Made Safe.

A fixed wiring installation degrades quietly — behind sockets, in loft voids, inside consumer units. We inspect, test and code every circuit against BS 7671 on a fixed periodic schedule, then fix what the report flags, matched to your property type.

NICEIC REGISTERED BS 7671 18TH EDITION ELECTRICAL SAFETY STANDARDS (PRS) 2020 REMEDIAL WORK INCLUDED
Why it matters

The standards we work to

Every inspection, code and remedial repair is carried out and certified against the specific standard your property type is held to.

BS 7671 (18th Edition)

Wiring regulations

The IET's national wiring standard — every periodic test is inspected and coded against its requirements.

Electrical Safety Standards (PRS) Regs 2020

Landlord duty

Requires a valid periodic test report at every private rented property in England, renewed at least every 5 years.

Housing Act 2004 / HHSRS

Housing health & safety rating

Electrical hazards form part of the statutory risk assessment local authorities use to assess rented homes.

Electricity at Work Regs 1989

Workplace duty

Requires fixed electrical systems in any workplace to be maintained to prevent danger.

RRFSO 2005

Fire risk overlap

Deteriorating fixed wiring is a recognised fire risk — periodic test findings feed directly into your fire risk assessment.

Building Regs Part P

Notifiable remedial work

Certain remedial electrical work identified during periodic testing must be notified under Part P before completion.

Observation codes

Every finding gets a code, every code gets a plan

BS 7671 sets a strict coding system for anything an inspection finds. We explain every code in plain terms and quote the remedial work before we leave.

C1

Danger present — immediate risk, made safe on site where possible

C2

Potentially dangerous — remedial action required without delay

C3

Improvement recommended — not a fail, but worth addressing

FI

Further investigation required, without delay

SATISFACTORY

No C1, C2 or FI codes — installation passes for the full interval

UNSATISFACTORY

One or more C1, C2 or FI codes present — remedial action required

Questions

Frequently asked

How often does a property need periodic testing?

Private rented properties in England need a valid periodic test report at least every 5 years under the Electrical Safety Standards (PRS) Regulations 2020. Owner-occupied homes have no legal requirement but a 10-year interval is generally recommended; higher-risk sectors like healthcare are inspected annually.

What happens if my periodic test comes back unsatisfactory?

An unsatisfactory result means at least one C1, C2 or FI code was recorded. C1 items are made safe immediately where possible; C2 and FI items need remedial work and a retest before the installation is confirmed satisfactory.

Do landlords have to fix every finding on the report?

Only C1 and C2 codes (and unresolved FI items) create a legal obligation to act. C3 items are recommendations for improvement, not a failure, though many landlords choose to address them at the same visit.

Is periodic testing the same as a Part P certificate?

No — a periodic test report covers the condition of an existing installation. Part P certification applies to new notifiable electrical work, which may follow from remedial items a periodic test identifies.
