Short answer: if a smart meter installer has refused to fit your meter, it is almost always because something on your side of the meter fails their safety check — old rewireable fuse board, undersized or perished meter tails, a missing or undersized main earth, no main bonding to gas and water, or an asbestos or wooden backboard. The engineer is not being awkward; their rules say they must abort and leave the existing meter in place. The fix is usually a short electrician’s visit rather than a full rewire: bonding and earthing work runs £120–£450 labour only, new tails £108–£180, and a full consumer unit replacement starts at £550 labour with the board and devices at cost. Most jobs are done in a morning, and we give you the certificate the supplier asks for. Call 07407 627542.
Why did the smart meter installer refuse to fit my meter?
Every energy supplier works to the same industry safety rules for meter work. Before the engineer disconnects anything, they check the state of the installation around the meter. If they find something that could make the job unsafe — for them on the day, or for you afterwards — they are required to stop, leave your old meter working, and hand you an abort or “no access to install” notice that lists the reason.
The wording on those notices is rarely helpful. “Customer installation defect”, “inadequate earthing”, “no means of isolation” and “unsafe consumer equipment” all mean the same practical thing: the electrical work between your meter and your fuse board needs sorting before they will come back.
It is worth knowing that the engineer usually cannot fix any of it themselves. Their remit stops at the meter. Everything from the meter tails onwards is the property owner’s responsibility — see our guide on who is responsible for the main fuse, cut-out and meter tails if you want the dividing line explained properly.
Is the engineer allowed to refuse?
Yes. A meter exchange means pulling live cables out of a meter in your hallway or cupboard. If the earthing is not proven, or the tails crumble when touched, or the board behind them is a 1970s rewireable unit with no RCD protection, the engineer is carrying the risk. Suppliers back their staff on this, and arguing with the person on your doorstep will not change the outcome.
The useful thing is that an abort is not a black mark against you. Once the defect is fixed and you can show it has been done by a registered electrician, you ring the supplier, rebook, and the install goes ahead normally. We have had customers back on the schedule within a week.
What faults stop a smart meter installation?
These are the ones we are called out to most often across North and East London:
- No main earth, or an undersized one. Older terraces around Tottenham, Edmonton and Walthamstow often have a 6mm² earth where 16mm² is now expected on a PME supply. The engineer will test for it and stop if it is missing or too small.
- No main protective bonding. The 10mm² green-and-yellow cables clamped to the incoming gas and water pipes within 600mm of the meter. Missing bonds are the single most common abort reason in Victorian conversions.
- Meter tails too small, too long or perished. 25mm² is the modern standard. Old 16mm² tails, or rubber-insulated ones that have gone hard and cracked, will fail the visual check straight away.
- Rewireable fuse board or a board with no RCD. A cast-iron or Wylex wooden-backed unit behind the meter is treated as unsafe consumer equipment.
- Asbestos or combustible backboard. Common in pre-1980 cupboards. The engineer will not drill or disturb it.
- No means of isolation. Nowhere for them to safely kill the supply while working.
- Water ingress, burning smell or heat damage around the meter or board.
- No safe working space. A meter boxed into a cupboard behind a washing machine, or a board so close to the meter that the tails cannot be dressed properly.
If the board itself is the problem, our five signs your fuse board needs replacing guide will tell you quickly whether you are looking at a repair or a replacement.
What does it cost to fix?
All prices below are labour only and include VAT. Materials — cable, clamps, boards and devices — are itemised separately at cost. Our minimum charge on any job is £108 inc VAT (£90 + VAT), which covers attendance and the first hour on site.
| Job | F & A price (labour only, inc VAT) |
|---|---|
| Attend, inspect and report so the supplier can rebook | £108 (minimum charge, covers the first hour) |
| Replace meter tails with 25mm² and fit a connector block | £108–£180 |
| Upgrade the main earthing conductor to 16mm² | £150–£280 |
| Main protective bonding to gas or water, per service | £120–£220 |
| Earthing conductor plus both bonds in one visit | £280–£450 |
| Consumer unit replacement (RCBO board with SPD) | From £550, board and devices at cost |
| EICR if the supplier wants the whole installation proved | From £140 — see our EICR cost guide |
| Certificate for the supplier (Minor Works or EIC) | Included with the work |
The honest range for a typical abort is £150–£450. Most are bonding and tails, not a new board. If someone quotes you £900 to “make it smart meter ready” without having looked in the cupboard, get a second opinion.
Do I need a whole new fuse board, or just the bonding and tails?
It depends entirely on what the engineer wrote down. Bonding, earthing and tails are standalone jobs — an hour or two, certificated with a Minor Works Certificate, and nothing else in the flat is disturbed.
You need the board doing when it is a rewireable unit, when there is no RCD protection at all, when the casing is plastic and showing heat damage, or when there is physically no way to land new 25mm² tails into it. In that case you are looking at a full replacement from £550 labour, which also clears most of the other defects at the same time because a new board comes with a main switch the engineer can isolate at. Our fuse board replacement page covers what is involved and how long it takes.
One thing worth saying plainly: an aborted smart meter fit is not, on its own, a reason to replace a healthy board. We will tell you if the cheap fix is the right fix.
Who pays — me, my landlord, or the energy supplier?
The supplier owns everything up to and including the meter: the service head, the main fuse and the tails between cut-out and meter. If something there is damaged, that is their cost and their engineer’s job to arrange.
Everything from the meter onwards — your tails, your earthing, your bonding, your consumer unit — belongs to the property. In an owner-occupied home, that is you. In a rented home, that is the landlord, and they cannot pass it to the tenant: the same duty that sits behind the five-yearly landlord EICR covers this work too. Tenants who have been told otherwise should read our note on tenants’ rights and landlord responsibilities.
Some suppliers will contribute towards bonding work when the abort was their own engineer’s finding. It is not guaranteed and it is not a legal right, but it costs nothing to ask when you ring to rebook.
How quickly can it be sorted?
For a straightforward bonding and tails job in our home patch — Haringey, Hackney, Enfield, Waltham Forest, Islington, Camden, Newham and Tower Hamlets — we can usually be there within a day or two and finish in a morning. Send a photo of the meter cupboard and the abort notice when you call and we can normally tell you the price before we set off.
The longer part is rebooking the supplier, which can run to a couple of weeks at busy times. Book the electrician first, then ring the supplier with a date you know you can keep.
What paperwork will the supplier want to see?
Bonding, earthing and tails work is certified with a Minor Electrical Installation Works Certificate. A new consumer unit gets an Electrical Installation Certificate and is notified under Part P through our NICEIC registration. Either document names the installation, the work done, the test results and the registered contractor — that is what the supplier’s rebooking team needs.
If the abort notice says something broad like “unsafe installation” rather than naming one defect, the supplier may want a full EICR instead. That is a survey of the whole installation with a satisfactory or unsatisfactory verdict, and it is the right document for a landlord to be holding anyway.
What if it is a rented flat or an HMO?
Same rules, tighter timescales. A licensed HMO is inspected more often and the council can ask for evidence, so an aborted meter fit that exposes missing bonding is worth clearing immediately rather than at the next renewal — our HMO EICR page covers what borough licensing teams in North London actually ask for. Where a converted house has one supply feeding several flats, the meter engineer may also flag the way the supply is split; that job is explained in our guide to a landlord’s board and split supply.
Smart meter refusals — FAQs
Can I refuse a smart meter instead of paying for the work?
You can decline a smart meter; suppliers cannot force one on you. But the defects the engineer found do not go away when they drive off. Missing main bonding or a perished earth is a genuine safety problem whatever meter is on the wall.
The engineer said “no earth”. Is my flat dangerous right now?
Treat it as urgent but not necessarily an evacuation. It means the protective devices may not disconnect quickly enough in a fault. Do not ignore it, and if you also have tripping, burning smells or warm sockets, call an electrician the same day — that is what our emergency electrician cover is for.
Will you talk to my energy supplier for me?
We will give you the certificate and a plain-English line describing exactly what was done, which is what their rebooking team asks for. We cannot book the meter appointment on your behalf — suppliers only take that from the account holder.
Can you do the work on the same visit as the survey?
Usually yes for bonding, earthing and tails, provided we know roughly what we are walking into. A board replacement is booked separately because the power is off for several hours and we may need the supplier to pull the meter.
Does new bonding mean the meter fitter will definitely come back?
It clears the defect they recorded. If they listed more than one, all of them need doing — which is why we photograph and price the whole list rather than just the headline item.
Do you cover my area?
We work across North and North East London from our Tottenham N15 base. Check the areas we cover.
