How often does a rented property in Harlow need an EICR?

At least every five years. The landlord must give the tenant a copy of the report and, where remedial work is required, complete it within 28 days. Two things changed recently and most published guides have not caught up: the maximum financial penalty is now up to £40,000 per breach, not £30,000 — regulation 11(2)(b) was substituted by the Extension to the Social Rented Sector Regulations 2025 and the new figure came fully into force on 1 May 2026 — and the duty now reaches social landlords too, with pre-existing social tenancies needing to comply by 1 November 2026.

Electrician Harlow: what the work costs and how to hire safely

Q: How much does an electrician cost in Harlow?

Harlow sits in the published South East band, roughly £55–£75 an hour, rather than the £45–£65 UK average — local labour competes with London work. Domestic day rates are commonly £250–£300. But most work is priced per job, not per hour: an EICR runs about £79–£150 depending on circuit count, a consumer unit replacement £450–£750, and a full rewire on a three-bedroom house £5,500–£8,500 before plastering. Comparing hourly rates between quotes tells you very little; comparing what each quote assumes about the existing installation tells you everything.

Q: Do I need a registered electrician to change a consumer unit?

Yes. Replacing a consumer unit is notifiable work under Part P of the Building Regulations in England and Wales. Using an electrician registered with a competent person scheme means they can self-certify the work and notify Building Control for you. If they are not registered, you must notify Building Control yourself before the work starts, and pay their fee.

An independent guide to electrical work in Harlow and the CM17–CM20 postcodes. No sales pitch — what each job involves, what it typically costs, which jobs are notifiable by law, and how to check a contractor is on a competent person register before you let them near your consumer unit.

The one check worth doing first. Before you book anyone, search their name or company on the Registered Competent Person Electrical register. It covers NICEIC, NAPIT, ELECSA, STROMA and the other schemes in one place. It takes thirty seconds and it is the difference between certified work and an unnotified job that shows up on your searches when you sell.

What electrical work costs in Harlow

These are indicative ranges for West Essex, not quotes. Prices move with access, the age of the existing installation and whether the work is notifiable. Treat anything far below the bottom of a range as a reason to ask what has been left out.

Job	Typical 2026 range	Rough timeframe	Notifiable?
EICR (electrical condition report)	£79–£150	2–3 hours	No — it is an inspection
Consumer unit (fuse box) replacement	£450–£750	Half a day	Yes — Part P
Full rewire, three-bed house	£5,500–£8,500 +£800–£2,500 plastering	5–7 days 3–4 weeks all-in	Yes — Part P
EV charger installation	£800–£1,500 less grant, if eligible	Half a day	Yes — new circuit
Power to a garage or outbuilding	£400–£2,500	1–2 days	Yes — new circuit
PAT testing	£1–£3 per item +£40–£80 minimum	Per visit	No
Extra socket or lighting point	£80–£150 per point	1–2 hours	Depends on location
Fault finding / diagnostic visit	£100–£200 first hour	1–3 hours	No

Two of those rows are worth reading twice. The rewire figure is the electrician's price — replastering is usually not in the quote, which is the single biggest cause of budget shock on that job. And the PAT row is mostly a minimum fee: for a small office you are buying a visit, not the tests. Full breakdowns on house rewiring cost and PAT testing cost — and if you are letting the property, the certificate you are legally required to hold is covered on landlord electrical safety certificate, where the maximum penalty rose to £40,000 in May 2026.

Chart of a three-bed rewire cost: electrical work up to £8,500, replastering up to £2,500, decorating up to £2,000, floors up to £1,000, giving a realistic all-in of £8,500 to £13,000 over three to four weeks. — The quote you are shown is the first bar. Replastering is usually not in it, which is the single biggest cause of rewire budget shock — see house rewiring cost.

Which board have you got? Count the test buttons

You can place your own installation within about thirty seconds without opening anything. The number of test buttons on the front of the board tells you which generation you have, and that decides whether replacement is urgent, worth doing eventually, or unnecessary.

Four consumer unit generations: no test button means rewireable fuses or MCBs with no RCD protection; one or two buttons means a dual-RCD board where one fault kills half the house; one button per circuit means an all-RCBO board, which is the target. — No test button at all means you have no RCD protection. Fuse box or consumer unit? walks each case, and consumer unit replacement cost has 2026 prices.

Which jobs you cannot legally do yourself

Part P of the Building Regulations covers fixed electrical installations in dwellings in England and Wales. Some work is notifiable — Building Control has to be told, and the work certified. Replacing a consumer unit, installing a new circuit (an EV charger, an electric shower, a garden supply) and most work in a bathroom zone all fall inside it. Replacing a like-for-like socket or light fitting on an existing circuit generally does not.

The practical consequence is about paperwork as much as safety. A registered electrician self-certifies and the certificate arrives with you. An unregistered one means you notify Building Control yourself, in advance, and pay for it — and if nobody did either, the missing certificate surfaces during a sale. See EICR testing and certificates for what the paperwork should look like.

Electrical fault finding — tripping RCDs, dead sockets, lights that flicker under load, and why diagnosis is charged separately from the repair.
EICR certificate cost — what the codes C1, C2, C3 and FI mean, why an FI can fail a report with no C1 or C2 on it, and what drives the price.
Landlord electrical safety certificate — there is no document by that name in law, the penalty is now up to £40,000, and social landlords are in scope for the first time.
Consumer unit replacement cost — 2026 prices, and the dual-RCD versus all-RCBO decision that nobody explains but that decides whether one fault takes out half the house.
House rewiring cost — the all-in figure including the plastering that is never in the quote, and an honest test for whether you need a full rewire at all.
EV charger grant — all three schemes at 75% up to £500, and the blunt answer for owner-occupiers of houses, who get nothing.
PAT testing cost — and the HSE's own position that annual PAT is not a legal requirement, nor are labels or records.
Garage and outdoor electrics — what a supply to an outbuilding costs, and why the burial depth everyone quotes is not actually in the standard.
Lighting installation — downlights, outdoor and security lighting, and the loft-insulation clearance issue that catches most retrofits.
Commercial electrical work — where inspection intervals are set by the installation and its use rather than a flat five years.

EV charger grants: most people get nothing

Every current government chargepoint grant pays 75% of cost up to £500 per socket and closes on 31 March 2027. The part installer websites bury is who is excluded — and if you own and live in a house, that is you.

EV charger grant eligibility: owner-occupiers of houses get no grant, and neither does anyone without off-street parking. Flat owner-occupiers, renters, landlords and businesses are eligible at 75% up to £500 per socket. — Eligibility is a rule, not an offer — shopping around cannot change it. All three schemes, and what to do instead if you get nothing, on EV charger grant.

Before you hire anyone

Do one thing first: search the contractor on the Registered Competent Person Electrical register. One search covers NICEIC, NAPIT, ELECSA and STROMA, it takes about thirty seconds, and it is the check almost nobody does — here is how, and what registration does and does not mean. It matters on this domain in particular: the website that stood here before this one claimed to be "NICEIC Approved" while trading under the name of a real, unrelated electrical company that is registered with NAPIT. One search disproved it.

Then read the guides rather than the sales pages. Do I need to rewire my house? answers no for most people. Fuse box or consumer unit? tells you which of four generations of board you have in thirty seconds, and when to leave a working one alone. RCD keeps tripping walks the elimination test that finds the circuit yourself. How long does a rewire take covers the week of plaster drying nobody schedules, and the EV grant if you rent or own a flat covers the group the grant was actually designed for. All of them are indexed at guides and advice, with cross-cutting questions on the FAQ page.

The area this site covers

Harlow itself (CM17, CM18, CM19, CM20) and the surrounding West Essex and East Hertfordshire belt — Sawbridgeworth, Old Harlow, Church Langley, Potter Street, Roydon and across toward Epping and Bishop's Stortford. Harlow's housing stock skews heavily to post-war new-town builds, which matters more than it sounds: a lot of the original installations have been part-rewired once already, so consumer unit work here frequently turns up mixed cable ages and missing earthing at the point of the survey rather than at the quote.

Questions people ask

How much does an electrician cost in Harlow?

Harlow prices to the published South East band — about £55–£75 an hour — rather than the £45–£65 UK average, because the town sits inside the London commuter belt and local labour can take London work. Domestic day rates are commonly £250–£300. But most jobs are priced per job rather than hourly, and on a short visit you are buying a minimum charge, not an hour: see electrician hourly rates for why comparing rates between quotes is close to meaningless, and what to compare instead.

Do I need a registered electrician to change a consumer unit?

Yes. It is notifiable under Part P. A registered electrician self-certifies and notifies Building Control for you; otherwise you must notify them yourself before work starts.

How often does a rented property need an EICR?

At least every five years. The 2020 Regulations came into force on 1 June 2020, applied to new tenancies from 1 July 2020 and to all existing tenancies from 1 April 2021. The landlord must supply the tenant with a copy, and complete any required remedial work within 28 days.
