Red flags in a cheap electrical quote
A quote significantly below the others is worth asking about before accepting — check it includes a proper consumer unit (not a budget one that doesn't meet current standards), covers making good afterwards, and includes the certificate you're entitled to for notifiable work. Cash-only, no fixed address, and no registration number are all worth asking about directly.
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.
How electrician quotes work
Describe the job, including property type, access, and whether the work is notifiable if you know. Electricians use this to give an initial estimate, then confirm the final price after seeing the job in person — particularly for anything involving old wiring, where the scope can change once cables are exposed.
Tripping fuses or flickering lights? Common causes
A breaker that trips repeatedly usually means a fault on a specific circuit, not the consumer unit itself — an electrician can isolate which circuit is affected. Flickering lights are often a loose connection rather than a faulty bulb, and worth having checked rather than ignored, particularly in older wiring.
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.
Lighting design and circuit planning
Adding recessed downlights, under-cabinet lighting or dimmer circuits usually means new cabling even if you're keeping the existing consumer unit, since older lighting circuits weren't sized for LED transformers or multiple dimmer switches. Plan lighting changes before, not after, a room's redecorated.
Electrical safety for landlords
Since 2020, landlords in England must have an EICR carried out every 5 years and provide a copy to tenants. Failing to do so can result in a fine of up to £30,000. If an EICR flags unsatisfactory work, it has to be fixed within 28 days or a shorter period the report specifies.
Shared supplies in flats and converted buildings
In a converted property, it's worth checking whether your flat has its own independent consumer unit and meter, or shares a supply with other flats via a landlord's distribution board. Shared supplies can complicate straightforward jobs and sometimes need freeholder permission before any work starts — check this before booking rather than on the day.
