Electrician FAQs: Everything Kent Homeowners Ask (2026)

Electrical work is the trade where getting it wrong costs the most — in insurance claims, in resale value, and (at worst) in fires. The questions below are the ones we hear most often from Kent readers planning EICRs, rewires, EV chargers and lighting upgrades. Read them before you hire, and you'll know the difference between a £220 EICR and a £450 one, and why Part P exists in the first place.

How much do electricians charge per hour in Kent?

Kent electricians typically charge £55–£95 per hour in 2026, with most quoting around £65–£75/hour for domestic work. Rates climb in the west of the county (Tunbridge Wells, Sevenoaks, Dartford) and drop slightly in Medway and east Kent. Fixed-price jobs — EICRs, consumer-unit swaps, EV charger installs — are often better value than paying hourly, because the electrician has priced the risk and the paperwork in.

What does an EICR cost in Kent?

An EICR (Electrical Installation Condition Report) on a typical 3-bed Kent home costs £180–£260 in 2026. A 1-bed flat is £130–£180, and a 5-bed or older home with more circuits and outbuildings can reach £350+. For landlords, EICRs are a legal requirement every 5 years under the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020, and a Code 1 or Code 2 fault must be remedied within 28 days. See our Kent electrician directory for local firms who quote EICRs on the phone.

What's the difference between NICEIC and NAPIT?

Both NICEIC and NAPIT are UK-wide electrical competent-person schemes, which means an electrician registered with either can self-certify Building Regulations-notifiable work (Part P). NICEIC is older and slightly larger; NAPIT is generally a touch cheaper for the electrician to join, so some smaller firms prefer it. From a homeowner's point of view, both are equally valid. The only thing that matters is that your electrician is on one of them, and that their registration covers the scope of work — look for "Approved Contractor" or "Domestic Installer" on the card.

Do I need a Part P certificate in Kent?

Yes, for certain work. Part P of the Building Regulations covers electrical safety in dwellings. Notifiable work — new circuits, consumer-unit replacements, anything in a bathroom or kitchen that adds new cable runs — must be either notified to Building Control in advance or self-certified by a competent-person scheme registered electrician (NICEIC, NAPIT, ELECSA, etc.). Non-notifiable work (a like-for-like socket swap, replacing a damaged cable) doesn't need a certificate but still must comply with BS 7671. If you sell your home, your solicitor will ask for these certificates.

How much does a full rewire cost in Kent?

For a 3-bed semi in Kent, a full rewire typically costs £4,500–£7,000 in 2026, depending on age of property, access to floors and ceilings, and spec of the new installation. A 4–5 bed detached home runs £7,000–£12,000. Period properties (timber-framed, listed) and Victorian terraces with plaster and lath often cost at the top of the range because the first-fix is slower. Most Kent electricians offer to take the rewire in stages over two or three visits so you don't have to move out.

How long does an EICR take?

A standard EICR on a 3-bed Kent home takes 2.5–4 hours on site. A 1-bed flat is usually 1.5–2 hours, and a 5-bed or older property with many final circuits can run to 5–6 hours. You'll need the electrician to isolate circuits in turn, so expect the power off for short periods through the visit. The written report lands by email within 2–3 working days, sometimes on the same day for smaller properties.

Can any electrician install an EV charger?

No. To install a home EV charger and claim the OZEV EV chargepoint grant (where still eligible), the installer must be OZEV-authorised and the chargepoint must be on the OZEV approved list. The installer must also be Part P registered (NICEIC or NAPIT is standard) and — for chargers over 3.6 kW — notify the local DNO (UK Power Networks in Kent) under G98 or G99 rules. A general electrician without OZEV authorisation can wire the final circuit but cannot activate the grant. See our EV charger installer guide.

What's a consumer unit and when does it need replacing?

The consumer unit (fuse board) is where your home's mains supply splits into the individual circuits. Older boards with rewireable fuses or plastic cases from before 2016 generally need replacing — the current 18th Edition of BS 7671 requires metal-cased units in domestic dwellings and RCBO protection on each final circuit. A typical consumer-unit replacement in a Kent home costs £500–£900 fitted, and the electrician will issue an EIC (Electrical Installation Certificate) on completion.

Are Kent electricians available for emergency call-outs?

Yes. Most Kent towns have electricians who run a 24-hour emergency service for issues like total power loss, burning smells from a consumer unit, or tripped RCDs that won't reset. Emergency call-out fees typically run £90–£160 outside working hours, plus an hourly rate of £90–£130. For non-urgent issues (a dead socket, a flickering light) the emergency premium is rarely worth it — book a next-day visit instead.

Do I need a certificate for every electrical job?

Not every job, but every notifiable job (anything new under Part P). A Minor Works Certificate covers small additions to existing circuits (a new socket off a ring main). An EIC (Electrical Installation Certificate) covers new circuits, consumer-unit changes, rewires. An EICR is the periodic safety check. Keep all three types in your home file — solicitors ask for them on sale, and your home insurance can refuse claims arising from uncertified electrical work.

How much does it cost to add a socket in Kent?

Adding a single spurred socket off an existing ring main costs £70–£120 fitted on a normal weekday visit in Kent. A double socket is similar — the outlet itself is a small part of the cost. Running a new dedicated circuit from the consumer unit (for an oven, say) costs £180–£350. If the electrician has to chase walls and make good, budget another £60–£100 for the plastering, which most electricians subcontract.

Can I do my own electrical work in Kent?

Legally, a homeowner may do some electrical work in their own home — replacing a like-for-like fitting, for example. But any notifiable work under Part P must be either certified by a competent-person scheme registered electrician or notified to Building Control in advance (for a fee, typically £200+). Insurers, mortgage lenders and buyers want to see the paperwork. For any circuit changes, adding sockets in bathrooms or kitchens, or consumer-unit work, use a registered electrician — it's faster and cheaper than notifying.

What's the difference between an RCD and an RCBO?

An RCD (Residual Current Device) protects against earth-leakage faults — it trips if current leaks to earth, protecting against electric shock. An RCBO combines RCD protection with MCB (overcurrent) protection on a single circuit. Modern 18th Edition consumer units typically fit an RCBO per final circuit, so a fault on one circuit (say, the kitchen ring) no longer takes out the lighting and upstairs sockets as well. If your board still uses dual-RCD protection and a fault keeps cutting half the house, an RCBO upgrade often solves it.

What should a Kent electrician provide after the job?

A written invoice with an itemised parts and labour breakdown, the appropriate certificate (EIC, Minor Works, or EICR), and — for Part P notifiable work — a Building Regulations Compliance Certificate issued under their competent-person scheme. You should also get manufacturer paperwork for any new consumer unit or switchgear. Store everything; a missing EIC when you come to sell is one of the most common causes of a conveyancing delay.

How do I find a reliable electrician in Kent?

Shortlist three: one from a trade scheme search (NICEIC or NAPIT), one from our Kent electrician directory, and one from a personal recommendation. Ask all three for a written quote for the same scope, and check all three registrations independently before work starts. Don't pick purely on price — the cheapest quote is often missing items the other two included, and those extras tend to appear on the final invoice.
