Best Practice Guide 1
Replacing a consumer unit in domestic premises
Practical guidance for designers, installers and inspectors when a consumer unit or main switchgear is being replaced on installations wired to earlier editions of BS 7671 — how to identify and protect against the dangerous conditions that often surface during a change-over.
Best Practice Guide 2
Safe isolation procedures
The step-by-step procedure for making AC low voltage installations (≤1000 V) dead, verifying isolation and locking off — the single most important routine for keeping electricians and other trades safe on site.
Best Practice Guide 3
Connecting a microgeneration system
Guidance covering the safe connection of small-scale generation (solar PV, battery, small wind) to a domestic installation. Currently being rewritten by Electrical Safety First and temporarily unavailable.
Currently being rewrittenBest Practice Guide 4 · Paul's working reference
Electrical installation condition reporting (EICR)
The definitive guide on how to apply the C1, C2, C3 and FI classification codes to observations recorded during periodic inspection and testing. This is the reference Paul works to for every EICR — see the dedicated EICRs page for how the codes translate into real-world outcomes.
Best Practice Guide 5
How electrical installations impact fire performance of domestic premises
How installation work — cable routes, penetrations, accessory boxes — affects the fire performance of walls, floors and ceilings that must contain fire or support load for a set period, and what to do to keep those provisions intact.
Best Practice Guide 6
Portable and stationary appliance testing in private rented accommodation
What landlords should consider when managing the ongoing safety of electrical equipment and appliances supplied to tenants as part of the tenancy — how to plan and record checks proportionate to risk.
Best Practice Guide 7
Ongoing accuracy and consistency of electrical test equipment
BS 7671 doesn't mandate formal calibration, but test results only mean something if the instrument does. The guide sets out a workable system for confirming and recording that test kit stays accurate — the standard Paul works to for every set of test results.
Best Practice Guide 8
Selection and use of plug-in socket-outlet test devices
The limits of plug-in socket testers — why even the more advanced devices cannot on their own confirm a socket-outlet is safe, and how they should (and shouldn't) be used alongside a proper inspection and test.
Best Practice Guide 9
Safe installation of retrofit LED lamps
Risks associated with self-ballasted LED replacements for tungsten, CFL and fluorescent lamps — shock risk during installation and maintenance, and the fire risk from low-quality products or badly-executed fluorescent conversions.
Best Practice Guide 10
Electrical safety standards in private rented accommodation
The minimum standard of periodic inspection and testing needed to meet UK private rented sector legislation, and to confirm whether an installation is safe for continued use. Essential reading for landlords, agents and inspectors.
Best Practice Guide 11
Electrical safety in communal areas
Electrical safety in the shared spaces of blocks of flats and similar buildings — written primarily for landlords, management companies and managing agents, but a useful reference for contractors working on communal systems.
Why this matters to you
BS 7671 sets the requirements; the Best Practice Guides show how to meet them on real jobs. When Paul quotes for a consumer unit change, an EICR or a rewire, the classifications, procedures and test discipline behind the paperwork trace directly back to these documents. That's the difference between a report that stands up to scrutiny and one that doesn't.
