Your House Rewiring Worries Answered in Hendon
Worried about disruption, moving out, losing power or paying for more work than your home needs? Here is what we check and agree before rewiring starts.
Will rewiring make a huge mess of my home?
Rewiring needs access to cable routes, so some lifting, drilling or wall chasing may be necessary. Before quoting, we explain where access is likely to be needed, protect the working areas and state what electrical making-good is included and what will still need a decorator.
Will I need to move out or be left without power?
That depends on the scope, layout and whether the property is occupied. We agree the safe working plan before starting, explain when circuits must be switched off and, where practical, sequence the work so essential power can be restored between stages. We confirm after the survey whether staying in the property is realistic.
Does the whole house really need rewiring?
Not always. Inspection and testing establish which existing circuits are safe and suitable to retain. If a partial rewire is the sensible option, the quotation separates retained wiring from new work and explains why; we do not recommend a full rewire from property age or an old fuse box alone.
How will I know the price, timescale and exactly what is included?
After the survey, the written quotation sets out the agreed rooms and circuits, accessory positions, cable routes, testing, certification, making-good responsibilities and expected programme. Any requested change or additional fault is discussed before it becomes extra work.
House Rewiring in Hendon NW4
Hendon properties do not all present the same electrical layout. The survey separates Victorian & Edwardian Terraces from 1930s–1950s Council & Private Semis before the work is specified.
That distinction guides access, circuit testing and the written house rewiring scope without relying on unsupported assumptions about the address.

Signs Your Hendon Home Needs Rewiring
Many homes in Hendon (NW4) were built between the 1930s and 1970s. Many still have outdated wiring that poses a real safety risk. Here's what to look out for.
Tripping Fuses or Circuit Breakers
If your fuse box trips regularly — especially when using multiple appliances — your wiring can't handle modern demand. One of the most common signs we see in NW4 properties.
Burning Smells or Scorch Marks
Any burning smell from sockets, switches or your fuse board is a serious warning sign. Scorch marks around sockets indicate arcing — a major fire hazard needing immediate attention.
Flickering or Dimming Lights
Lights that flicker or dim when you switch on appliances suggest loose connections or wiring struggling under load — signs of deteriorating electrical installation.
Old Round Pin Sockets or Rubber Wiring
Round pin sockets, brown or black rubber-coated cables, or cloth-wrapped wiring are signs of pre-1960s installation. These must be replaced — dangerous, not just outdated.
Not Enough Sockets
Relying on extension leads throughout the house means your wiring wasn't designed for modern life. Especially common in Victorian and Edwardian properties across NW4.
Failed EICR or No Certificate
A recent EICR in Hendon with a C1 or C2 code, or no certificate at all, means a rewire is often the most cost-effective solution over multiple repairs.

House Rewiring Planning for Hendon Property Types
Four property situations that change access, testing and the practical scope in Hendon.
Swipe to explore all property types
Victorian & Edwardian Terraces
📍 Brent Street, Watford Way, Hendon Park, Vivian Avenue
Does Victorian & Edwardian Terraces need a full rewire, or can safe wiring remain? Hendon is one of Barnet twenty conservation areas, where permitted development is restricted, so visible external work is checked against the designation first.
For Victorian & Edwardian Terraces, assessing house-to-flat supply differences means the scope separates wiring inside the property from communal, landlord-controlled or separately metered circuits before deciding what can remain. The written scope names every retained section rather than assuming the same answer for the whole property. The written scope follows the checked layout around Brent Street.
1930s–1950s Council & Private Semis
📍 Greyhound Hill, Sunny Hill Park, Parson Street, Queens Road
How will cable routes and making good be handled in 1930s–1950s Council & Private Semis? Floors, ceilings, original finishes and occupied rooms can limit the cleanest route. Chasing, lifted areas, visible containment and making-good responsibilities need to be clear before work starts.
When planning older-board circuit identification for 1930s–1950s Council & Private Semis, accessible voids, finishes and room use are surveyed before chases, lifted areas or visible containment are included in the quotation. This makes the disruption and making-good boundaries visible before the route is approved. The written scope follows the checked layout around Greyhound Hill.
Post-War Flats & Regeneration Developments
📍 Hendon Central, West Hendon, Mill Hill East, Brent Cross
Can power remain available while Post-War Flats & Regeneration Developments is rewired? Some circuits may remain available during planned stages, but this depends on safe circuit boundaries, access and occupancy. A generic promise to keep every room powered would be misleading.
Rewiring around managed-building access in Post-War Flats & Regeneration Developments requires a defined sequence: isolation and access are agreed with the relevant owner, tenant or managing agent so separately occupied areas are not treated as one installation. Those constraints are agreed at survey stage and carried into the written programme. The written scope follows the checked layout around Hendon Central.
Extended Terraces & HMO Properties
📍 Throughout Hendon NW4 — rear extensions, HMO conversions, multi-occupancy. See all our Barnet rewires
Can Extended Terraces & HMO Properties be planned for future electrical, data and security needs? Socket, lighting, appliance, data and security positions are easier to coordinate before routes close. Future provision still has to match the verified supply and consumer-unit design.
When Extended Terraces & HMO Properties need provision for loft and extension provision, likely appliance, work, data and security requirements are planned before finishes close the routes, with practical spare capacity identified at the board. The final design remains tied to the verified supply and circuit plan. The written scope follows the checked layout around Throughout Hendon NW4.

Property-specific questions for Hendon, followed by practical answers about house rewiring.
Barnet house rewiring coverage · North London house rewiring
What does it cost to rewire a 2, 3, or 4-bedroom house in Hendon?
Honest pricing depends on house size, age, and how much wiring already exists. As a guide for Hendon properties:
- Partial rewire (kitchen, 1-2 rooms, or consumer unit only): from £2,500
- Full 2-3 bedroom house (typical NW4 terrace or NW4 semi): £4,500–£6,500
- 4+ bedroom or larger Victorian (the bigger Victorian properties): £7,500–£10,000+
That includes materials, full first-fix and second-fix, new RCBO consumer unit, testing, certification, and Part P sign-off. Plaster patching with bonding plaster is included. Skim coats, painting, and re-decoration aren't — those are a decorator's job. Older Hendon stock with solid floors or lath-and-plaster walls adds 1-2 days of cable-routing time, which we factor into the quote upfront — not at the end. You get a fixed written quote after a free survey. No day-rate creep.
How long does a rewire take, and can I live in the house with kids or pets while it's happening?
For most Hendon homes the work runs 5-10 working days end-to-end. A typical 3-bed semi takes 6-7 days; a Victorian terrace with solid floors closer to 8-10. We work room by room so you can stay living there, and we maintain power to circuits we're not actively working on — fridge/freezer stays running, Wi-Fi stays up most of the time, and we do full power isolation only for short windows when connecting the new consumer unit (you get 24 hours' notice, never a surprise).
It's still disruptive: noise during wall chasing, dust during first-fix, and rooms come out of action one at a time. If you've got a baby, working from home, or pets nervous of strangers, some Hendon clients go to family for the noisiest 2-3 days — but most ride it out fine.
How do I actually know if my house needs a full rewire, or is it just the fuse box?
Honest answer: most "rewire" calls we get in Hendon turn out to be either consumer-unit-only jobs or partial rewires — not full rewires. The signs that genuinely point to a full rewire:
- Black rubber-insulated cable in the loft or under floorboards (1950s and earlier)
- Cloth-covered cables behind switches (pre-WWII installations, common in Brent Street and Brent Street terraces)
- No earthing to lighting circuits, or only two pins in some sockets
- Multiple circuits failing on EICR (small failures don't justify a full rewire)
If your fuse box just looks old (a wirewound or rewireable type), that alone is just a consumer unit job — usually £800-£1,200, not £6,000+. Frequent tripping on its own usually points to one bad circuit or appliance, not the whole house. We'll tell you which it is during the free survey, and we don't push rewires that aren't needed.
My EICR failed with C1 or C2 codes — does that mean I need a full rewire?
Usually not. A failed EICR (a single C1 or one or more C2 codes) means specific items need fixing, but a full rewire is overkill in most cases we see. The most common Hendon EICR failures:
- No RCD protection on circuits → fixed by replacing the consumer unit (£800-£1,200)
- Damaged insulation on lighting drops → fixed by replacing the affected circuits, not the whole house
- Missing bonding to incoming gas/water → 1-day remedial job
- Borrowed neutrals or shared circuits → targeted rewire of those circuits only
If your EICR has "rewire recommended" across most circuits with codes flagging cloth insulation throughout — then yes, the whole house probably does need it. Send us the report and we'll give you a straight read: targeted remedial work, partial rewire, or full rewire — and the actual price for each.
Can I do a partial rewire — just the kitchen, ground floor, or consumer unit?
Yes, and it's often the right call for Hendon homeowners renovating in stages. Common partial scopes we do:
- Kitchen ring + lighting (tied to a kitchen renovation): £1,500-£2,500
- Ground floor or upstairs only: roughly half the price of a full rewire, sensible if one half clearly has older wiring
- Consumer unit + earthing only: £800-£1,500, fixes the most common safety failures
The catch: if your incoming supply or main earth needs upgrading, that's a one-off cost regardless of how much you rewire. We'll tell you whether partial works for your specific property — sometimes the saving is real, sometimes a full rewire is actually better value if you'd otherwise be back in two years.
Should I rewire before or after a kitchen extension, loft conversion, or back-of-house renovation?
Almost always before the finishes go in, at the same time as the structural work. This is where most homeowners waste money — rewiring the existing house, then ripping walls open six months later for the extension.
Practical order on a typical Hendon renovation:
- Rewire + new consumer unit alongside the build's first-fix
- New kitchen/loft/extension circuits installed at the same time, fed from one new board
- Second-fix electrics with the kitchen install or after plastering
- Single Part P Building Regulations Compliance Certificate covers everything
For loft conversions specifically: the new loft circuit and any added consumer unit capacity can be done as part of the loft build. Same for a side-return extension — we run new cabling for the kitchen and bi-folds without disturbing the rest of the house. Ask us to coordinate with your builder; we've worked alongside most of the Hendon ones.
How disruptive is it really — walls, floors, plaster, wallpaper, dust?
Honest version: it's noisy and dusty for 2-3 days during first-fix, much calmer after that. Specifically:
- Walls: we chase shallow channels for cable drops — about 1-inch deep. We patch them with bonding plaster, leaving them ready for a decorator to skim and finish. Wallpapered walls need a strip peeled back, which has to be re-papered after.
- Floors: suspended timber floors (most Hendon terraces) need carpet/laminate lifted and floorboards lifted in strategic spots — refitted carefully, but they may show. Solid concrete floors (a lot of Hendon ex-council semis): we route through ceilings instead.
- Lath-and-plaster ceilings (Victorian houses around Brent Street): we minimise drilling; sometimes patch repairs are needed.
- Dust: unavoidable during chasing. We use dust extractors at source, sheet up before starting, and clean down each evening — but expect a deep clean afterwards.
Plaster patching with bonding plaster is included. Skim coats, finishing, painting, and any re-decoration are a decorator's job, not ours.
Can you rewire a Victorian or Edwardian property without ruining the original features?
Yes — and it's most of what we do in Hendon. The Victorian terraces along Brent Street and surrounding streets have specific quirks:
- Lath-and-plaster ceilings — we work around them where possible, dropping cables into wall cavities and routing via the floor void above, so the original ceiling stays intact.
- Original cornicing and ceiling roses — we don't drill through them. Switch drops route alongside, not through.
- Brass, Bakelite, or period switches — if you want to keep them, modern smart-control kits can sit behind them invisibly. We'll tell you which can stay and which can't (anything pre-1955 with no earth has to come out).
- Original floorboards — we lift carefully and re-fit. Tongue-and-groove pine in good condition we keep; rotten or split boards we replace.
Tell us what features matter to you before we start. We've never had a customer regret the conversation, and we've often saved features a previous quote planned to remove.
I'm buying a house in Hendon — the survey flagged "old wiring". What should I do?
Three steps, in order:
- Get an EICR before exchange if you can. A homebuyer's survey only flags wiring as "outside scope" — they don't lift floorboards. An EICR is £180-£280, takes 2-3 hours, and gives you a real answer. We can usually book within a few days.
- Use the EICR to negotiate. If the report shows C1 or multiple C2 codes, that's documented evidence to drop your offer by the cost of remedial work — typically £1,500-£8,000. Sellers often accept rather than risk losing the sale.
- Don't panic about "old wiring" alone. A 1980s installation with a working consumer unit and RCDs may be perfectly serviceable for another 10 years. Truly dangerous installations (pre-1960s with no earth, burned or damaged cables) get flagged as C1 — that's the line, not just age.
Mortgage point: most lenders don't refuse mortgages over old wiring as long as the EICR is satisfactory or the seller agrees to remedial work before completion.
Will the new wiring support future high-load equipment, a heat pump, smart home, and home office circuits?
Yes — and it should. The point of rewiring now is not to be back in five years. What we include as standard on Hendon rewires:
- future high-load circuit allowance — spare 32A way on the consumer unit, labelled isolator at the meter end, ready for a 7kW or 22kW charger install
- Heat pump readiness — separate dedicated supply with the right cable spec from the start (saves money versus retrofitting later)
- Smart home wiring — neutrals to all switch positions (period houses often don't have these, which blocks smart switch installs later)
- Home office circuits — separate ring or radial, ideally with surge protection
- USB-C sockets in kitchen, lounge, or bedside areas if you want them
Specifying these up front during the rewire is a small incremental cost while we're already routing cables. Retrofitting them later — once walls are closed and finished — costs many times more because we'd need to chase walls, lift floors, and re-decorate. Tell us your future plans during the survey and we'll build the cabling around them.
Will I have power overnight and during the work?
Yes for most of it. Specifically:
- Power stays on overnight, every night — we leave you with a working consumer unit and at least one ring, lighting circuit, and fridge feed live every evening before we go.
- Phased outages during the day — when we're working on a circuit, that circuit is off. The rest stay live. You can usually still use kettle, microwave, fridge, and Wi-Fi from rooms we're not in.
- One full isolation window — when we swap the existing consumer unit for the new one (typically day 5-7). This takes 2-4 hours. We schedule it mid-morning, give 24 hours' notice, and warn you to defrost anything important.
If you're working from home, plan your critical calls or deadlines around the isolation day — we can flex which day if something is non-negotiable.
Should I rewire my house before selling? Does it actually add value?
Honest answer: only if the wiring is genuinely failing or unsafe — not as a value-add alone.
What works:
- Failing EICR + a buyer survey ahead — yes, rewire (or do remedial work) before listing. Buyers walk away from C1/C2 code lists, or they negotiate harder than the cost of fixing it.
- Pre-1970s wiring with no modern consumer unit — at minimum upgrade the consumer unit (£800-£1,200) so the EICR comes back satisfactory. That alone removes the survey objection.
- Working installation that's just "old" — usually no. The buyer benefits more from doing it themselves (sockets where they want, smart-home ready) than paying you to do it generically.
If you do rewire pre-sale: time it 1-3 months before listing so the certificate looks fresh. Photograph the new consumer unit, keep the certificate, list "fully rewired with Part P Building Regulations Compliance Certificate" in the marketing.
