We are NICEIC-approved, Part P registered electricians working the Blackhorse Lane corridor and Higham Hill, E17. That covers Blackhorse Lane and Blackhorse Road, Forest Road down to the station, Sutherland Road and the old Uplands works, Billet Road, Higham Hill Road and Sutton Road, Millfield Avenue, Priory Court, McEntee Avenue, Lawrence Avenue, Sinnott Road, Romany Gardens and Swansland Gardens, and the Coppermill Lane and Ferry Lane edge where Walthamstow runs out into the Wetlands. We are based at Ten 87 Studios on Markfield Road in Tottenham N15 — straight across the Lea, so this is a fifteen to twenty-five minute run for us depending on how the Ferry Lane bridge and Forest Road are behaving. Call 07407 627542 (or 07500 721453) and you will get a straight answer about what the job needs and what it costs.
This is one of the few parts of London where you can stand on one street and look at five different decades of wiring. The terraces behind Higham Hill Road went up from the 1870s. The council estate dates from 1920 and the slum clearance that started on Millfield Avenue. Priory Court was begun in 1946 and later rebuilt. The towers arrived in the 1960s and 70s. And since 2010 the old industrial strip along Blackhorse Lane and Sutherland Road has put up more than six hundred new homes, with the Blackhorse Lane Growth Area and the Creative Enterprise Zone still building. Each of those vintages fails in its own particular way, and knowing which one you are standing in before you lift a single faceplate saves everybody time.
What we do around Blackhorse Lane and Higham Hill
Day to day in E17 5 and E17 6 that means:
- EICRs — landlord certificates, pre-purchase reports, managing-agent inspections of communal areas in the new blocks, and periodic reports on the workshop and studio units.
- Consumer unit and fuse board replacements — including the dual-RCD boards fitted during the 2010–2014 conversion wave that are now nuisance-tripping, and the Wylex rewireable boards still sitting in the interwar houses.
- Fault-finding — intermittent trips, dead circuits, nuisance RCD operation, and the borrowed-neutral problems that come out of a house split into flats on one intake.
- Rewires and partial rewires — full house rewires on the Victorian and interwar stock, partial rewires where previous owners did the ground floor and stopped.
- Additional circuits — kitchen and utility radials, shower circuits, garden office sub-mains, EV charge-point circuits where the parking actually allows it.
- Smoke, heat and CO alarms to BS 5839-6, the Grade D1 interlinked systems landlords in Waltham Forest need.
- Emergency lighting and fire alarm work in the converted workshops, studios and the commercial ground floors.
- Three-phase work on the Sutherland Road and Uplands units — distribution boards, sub-mains, machine supplies, PAT testing.
If you are not sure which of those you need, ring and describe what is happening. Half the calls we take turn out to be a smaller job than the caller feared, and we would rather tell you that on the phone than charge you to find out.

The new Blackhorse Lane blocks: what we actually find
The flats built along Blackhorse Lane, Sutherland Road and Lockwood Way since 2010 are a different job from the rest of E17, and the problems are not the ones people expect. New wiring is rarely the issue. The issues are capacity, access and paperwork.
All-electric flats with no gas. A lot of these blocks run heating and hot water off a communal heat network or off individual electric systems, which means the flat’s whole load — heating, hot water, cooking, everything — sits on one supply. When somebody then wants a car charger or an electric shower added, the honest answer often starts with a load assessment rather than a price. We would rather do that assessment than fit something that trips the main switch every January.
Boards with no spare ways. Developers fit the board the original circuit schedule needed and not a way more. Adding a kitchen radial, a garden-room sub-main or a charge-point circuit means either a board change or a sensible reorganisation of what is already there, and that has to be worked out before anybody quotes.
Dual-RCD boards from the conversion wave. The 2010–2014 stock typically has a split-load board with two RCDs covering everything. One faulty appliance on one side takes out half the flat, which is why so many of these calls come in as “half the lights have gone”. Replacing with a full RCBO board fixes the symptom properly rather than chasing it circuit by circuit.
Who owns the fault. In a block, the landlord’s or freeholder’s supply, the riser, the sub-main and the meter cupboard are usually not yours, and the managing agent controls access to them. We will tell you plainly which side of the line a fault sits on, and put it in writing for the agent if that is what gets it fixed. Our page on EICRs on leasehold flats and communal areas goes through where the responsibility splits, and EV charging in a flat covers the permission side of it.
Newer does not mean certified. If you bought off-plan or took an assignment, the electrical installation certificate and the as-built circuit schedule should have come with the handover pack. They very often did not. If you are letting the flat you need something in writing, and whether a new build needs an EICR is a question we get most weeks.
The old industrial strip: Sutherland Road and the Uplands units
Blackhorse Lane was the Upper Lea Valley’s manufacturing edge, and a good deal of that fabric is still standing — now as studios, workshops, breweries, makers’ units and the creative workspace the council has been funding around the Blackhorse Collective. Electrically these are commercial installations wearing an industrial shell, and they throw up a consistent set of things:
- Three-phase supplies and TP&N boards where the original machine loads have gone and lighter tenants have moved in, leaving a wildly over-specified board with half its ways on a schedule nobody can read.
- Sub-divided units — one landlord’s supply split between four tenants, with no sub-metering and no clear boundary between whose circuits are whose. This is the single most common reason a commercial EICR here takes longer than the estimate.
- Surface-run containment added in layers over twenty years, with abandoned circuits still live at one end.
- Emergency lighting and fire alarm systems installed for the old use and never re-designed for the current layout, which is a problem the minute anyone asks for a certificate. See emergency lighting certificates.
- Portable appliance loads in workshop and studio spaces that need a real schedule, not a sticker — our PAT testing page explains how we price that.
If you are taking a unit on here, the two documents to ask for before you sign are a current EICR and a legible distribution board schedule. If the landlord has neither, that tells you something about what the first year will cost. Commercial EICR costs sets out what an inspection of a unit like this involves. Where a former workshop has been turned into flats, conversion EICRs is the closer fit.
Higham Hill’s older houses: five decades, five sets of faults
Away from the Lea, the housing stock here is unusually layered, and each layer has its own signature.
The 1870s–1900 terraces. Rewired at least once, often twice, often in stages. What we find is a modern board sitting over a mix of 1960s rubber-sheathed and 1980s PVC cable, lighting circuits with no earth at the switch, and a main earth clamped to a water pipe that has since been replaced in plastic — which quietly removes the earth. Main protective bonding to water and gas is the single most common missing item on an EICR in these streets.
The 1920s interwar council houses off Billet Road, Higham Hill Road and the Millfield Avenue area. Generous rooms, thin circuit provision: two sockets a room was the standard, so every one of these has had extensions spurred off spurs. Many are on TN-S supplies where the earth is the aged lead sheath of the service cable, and where that has degraded it is a job for the network operator before we can certify anything.
Priory Court and the post-war blocks. Begun in 1946 and rebuilt since, so what you find depends entirely on which phase your flat is in. Landlord’s risers, communal lighting and the flat’s own installation are three separate questions, and an EICR has to be clear about which one it covers.
The 1960s and 70s towers. Original rising busbars, landlord supplies feeding communal lighting and lifts, and individual flats that may have been rewired by the council in a programme or may not have been touched. Where a flat is now privately let, the landlord needs a certificate for their own installation whatever the block’s condition.
Divided houses on one intake. Plenty of the larger houses here are two or three flats on a single supply and a single meter position. That brings borrowed neutrals, shared circuits crossing the boundary between dwellings, and the question of who is legally responsible for what. Splitting the supply properly is a job worth doing before letting — see splitting a landlord’s board and supply.
Where something is wrong, you get it written down with a code and a price, not a verbal “that’ll need doing”. Our page on EICR remedial work costs shows how we price the follow-up.
Landlords and HMOs in E17
About half the households in this part of Walthamstow rent, a good share of that from the council, and the private side is a mix of converted terraces, ex-council flats and the new blocks. Under the 2020 Electrical Safety Standards you need a satisfactory EICR at least every five years, a copy to the tenant within 28 days, and remedials done inside 28 days of the report unless it says sooner. Interlinked smoke alarms on every storey and a CO alarm in any room with a fixed combustion appliance are separate duties with their own timescales.
Two things we would flag specifically for landlords round here. First, if your flat is in a block, your certificate covers your installation — it does not cover the communal risers, and an agent telling you the block has “a certificate” is not the same document. Second, if the property is a divided house on one intake, expect the inspection to take longer and expect C2s relating to shared circuits; that is normal and it is fixable, but it needs to be priced honestly up front.
Our landlord EICR guide covers the regulations in full, HMO EICRs covers licensed houses in multiple occupation, and smoke alarm installation covers the alarm duties. Licensing in Waltham Forest changes from time to time and varies by street — check the council’s current scheme for your address rather than relying on what applied last year.
EV charging around Blackhorse Road
Worth being straight about this, because the parking here decides it. If you have a driveway, a garage or an allocated off-street bay, a home charge point is a normal day’s work from £450 labour, subject to a load assessment on the supply. If you park on the street — which is most of Higham Hill — we cannot fit a wall point for you, and we will not run a cable across a public footway. Cross-pavement channels are a council scheme, not something an electrician can install on request, so that is a question for Waltham Forest rather than for us.
In the new Blackhorse Lane blocks the limiting factor is usually the landlord’s sub-main rather than your flat. Charging an allocated bay in an underground car park means the freeholder’s or managing agent’s permission, a load assessment on the block’s supply, and sometimes a separate metered circuit. We will look at it and tell you whether it is feasible before anybody spends money. See EV charger installation in Waltham Forest, EV charging in a flat, and when a charge point needs planning permission if you are in a conservation area or an Article 4 street.
Nearby areas we cover
Blackhorse Lane sits on the Waltham Forest border with Haringey — the River Lea and the Wetlands are the boundary, and Northumberland Park station is under a mile from Billet Road on the other side of it. We work both banks.

Blackhorse Lane electrician — common questions
How quickly can you get to Blackhorse Lane?
We are on Markfield Road in N15, across the Lea via Ferry Lane, so this is a fifteen to twenty-five minute run outside the worst of the Forest Road traffic. For urgent faults ring 07407 627542 and we will tell you honestly when we can be there rather than promising an hour we cannot hold to. If it is an emergency, see emergency electrician Waltham Forest.
My new-build flat trips when the heating and the oven are both on. Is that a fault?
Sometimes, and sometimes it is the installation doing what it was designed to do with more load than it was designed for. In an all-electric flat the two have to be told apart by measurement, not by guesswork: we check the board arrangement, the circuit loading and the main switch rating before recommending anything. If it turns out to be a capacity question, a board change on its own will not solve it.
Do I need an EICR if my flat was built five years ago?
If you are letting it, yes — the five-year duty applies regardless of age, and the handover certificate from the developer is not a substitute once five years have passed. If you are living in it, no legal duty applies, but if you never received the original electrical installation certificate it is worth getting a report so you have something on paper.
Can you certify a workshop unit on Sutherland Road?
Yes. For commercial units we quote after seeing the distribution board arrangement, because a three-phase board with an unreadable schedule is a different job from a single-phase unit with eight circuits. Expect from £220 for a straightforward unit, and expect us to ask who the landlord’s supply feeds before we start.
The house is split into two flats on one meter. Can you still do a landlord EICR?
Yes, but it needs to be scoped properly. Shared circuits crossing between dwellings usually attract C2 codes, and the honest fix is often splitting the supply rather than patching the report. We will inspect, code it accurately and price both options.
Are you actually NICEIC approved?
Yes — NICEIC-approved and Part P registered, working to BS 7671 18th Edition, fully insured, and Checkatrade approved with a 9.32 out of 10 rating from 242 reviews. Certificates are issued on completion for all notifiable work.
