How many quotes should you get?
Three is the usual recommendation — enough to spot an outlier (too cheap or too expensive) without asking so many tradespeople to survey your property that it wastes everyone's time. Make sure each quote is for the same scope of work, since a lower price sometimes just means less is included.
How often should wiring be tested?
The IET recommends an electrical inspection every 10 years for an owner-occupied home, 5 years for a rented property, and on change of occupancy for some property types. A periodic inspection is different from routine maintenance — it's a formal check against current wiring regulations, not just a visual look.
Wiring a loft conversion
A loft conversion typically needs new lighting and socket circuits, often a new consumer unit way if the existing one is already at capacity, and mains-wired interlinked smoke alarms are usually required by building control as part of the sign-off, not just recommended.
Do I need an electrical certificate to sell my house?
There's no legal requirement to provide one, but conveyancing solicitors routinely ask whether any electrical work done during your ownership was certified, and a missing certificate for notifiable work (a rewire, a consumer unit change, a kitchen or bathroom circuit) can hold up or complicate a sale. Keep any Electrical Installation or Building Regulations certificates with your house paperwork.
What affects the cost
Cost depends on the scope of the job, how much of the property needs to be accessed, the age and condition of the existing wiring, and whether the consumer unit needs upgrading. A single socket replacement is quick and low-cost; a full rewire in an older property takes longer, partly because of the making-good work afterwards.
What a good electrical quote should include
A proper quote should state the scope of work, whether it's notifiable under Part P, an itemised breakdown of labour vs materials, the certificate you'll receive on completion, and how long the job is expected to take. If a quote is missing any of these, ask before agreeing to the work.
Understanding the labour vs materials split
Materials — consumer units, cabling, sockets, fittings — are usually a smaller share of an electrical quote than labour, particularly for jobs involving lifting floors or chasing walls. If a quote seems unusually cheap, check whether it's using a lower-spec consumer unit or cabling than a competing quote, not just a lower labour rate.
Christmas lights and extension lead safety
Overloading a single socket with extension leads and adaptors, especially outdoors or over the festive period, is one of the more common causes of a winter electrical fault. Outdoor lights need outdoor-rated (IP-rated) connectors, and it's worth having sockets checked before peak season if your property's wiring is older.
