I don't entirely buy the safety aspect in the emails energy companies send out to persuade customers to have a smart meter fitted. Maybe if your meters are ancient or were installed by somebody dodgy previously, but really the energy companies are probably more fussed about the inaccuracies of old meters possibly losing them money.
When was the last time you had an inspection of the supply head and meter connections?
You do realise that screwed down cables can become loose over time due to heating and cooling of conductors? This is a very common cause of meter related house fires...
Any meter built or installed before 2001 will need to be replaced, its that simple, they have and will have come to the end of expected (certified) life, where as years ago we would test and recertify it has now become cheaper to replace the meter, in 2006 MID (
Measuring Instruments Regulations) meters were introduced (
https://www.gov.uk/guidance/mid-approved-gas-and-electricity-meters) and since then all meters installed and MID approved. There for they are approved for a lifecycle set out by the manufacture, most are 10-15 years iirc.
I've said it before and I will say it again, residential metering makes less money for suppliers than you would expect, especially with the cost of running large call groups and employing humans in the UK (most have a significant UK based call center now, although they tend to have centres in several other parts of the world for outbound dialing). Commercial metering or CT/Major business is where the money is at, my employer manages the supply for every ScrewFix (1726 stores not including distribution centers) and B&Q (300 not including distribution centers) in the UK and they are one client worth rought £18m pa. We supply the rail network (£2.3b over 3 years) and every Government office (not local but we do cover several of them too). In some areas we supply street lighting and CCTV power systems. Consumer Retail business is small fry compared to generation, whole sale energy prices are close to cost in value of nuclear and gas generation, due to constant maintenance and new builds. Where as Solar and Wind in the UK has paid for its self in less than three years in some installations.
Eon have been trying to replace my economy 7 meter now for a few years, every month or so they will call, tell me they need to change it. I explain that i can only do weekend appointments as i refuse to take an unpaid day off work to have one fitted. They say no weekend appointments are currently available and will add a note to my account and call me back once one is available. Following month another phone call, same thing, totally oblivious to the note that is meant to be on the account, tell me they have now added it and then rinse and repeat 3 years later lol still same thing.
They are now saying the radio signal is being turned off and it is now urgent... Yea well give me a weekend appointment then! you have had 3 years!!!
Eon do provide weekend appointments, as do nearly all suppliers bar a few of the smaller ones. They also provide late evening slots as do nearly all other suppliers.
If your E7 meter uses a radio teleswitch a smart meter will be your only option, I would be pushing for a new meter as hard a possible as come March 2025 when the Radio4 signal is switched off you can say goodbye to you heating and hotwater!
At the end of the day Suppliers are being FORCED to install smart meters as part of a Government idea it will help reduce our carbon footprint as a nation (it Wont). They honestly don't want to be doing it, every appointment costs roughly £400 in man hours and equipment that they are NOT allowed to add to the overall cost of your fuels (strict guidelines control what can be added to your fuel costs).
