If you’re thinking of installing an EV charger, underfloor heating, or something that uses more energy in your home, you may need to upgrade your main fuse for electricity. And if you do, you may also need to upgrade your meter tails. These are the cables that carry electricity to your meter.

We can arrange for an engineer to upgrade your meter tails for you. The cost of the upgrade is £120. This is reduced to £60 if you’re having a smart meter installed at the same time. To book a meter tails upgrade, or a combined upgrade and smart meter installation, contact us.

If you or anyone in your household is self-isolating or at risk from coronavirus (COVID-19), please delay your appointment or tell us if you need to cancel.

We’ll ask you some questions before we book your appointment

To make sure your meter tails upgrade goes smoothly we’ll ask you some questions when you get in touch.

If you’re also getting a main fuse upgrade, the date of your appointment 

The main fuse controls the amount of power coming into your home. If you’re upgrading your main fuse, we’ll need to arrange for an engineer to upgrade your meter tails before your main fuse upgrade.

The date and time you’d like the engineer to visit

Upgrading meter tails usually takes around 20 minutes. If you’ve asked us to install a smart meter at the same time, the appointment could take up to 3 hours. When you contact us, we’ll ask for the best date to visit, and which of the following time slots works best:

  • 8am to 12pm
  • 10am to 2pm
  • 12pm to 4pm
  • 2pm to 6pm

If you’re happy to pick a time slot from the ones we have available, we’ll book your appointment straight away. If not, we’ll send you some options and wait for you to tell us which one works for you.

If there is parking at your property

The engineer may need to carry heavy equipment, so they’ll need to park near your property. We’ll ask if there’s free parking or Pay and Display, or if the engineer will need a visitor’s parking permit.

If you have a dog

We’re big fans of pets, but we need to know this for the engineer's risk assessment. And we’ll ask you to keep your pets in another room during the installation to make sure the engineer can work safely.

If there’s any information we should pass on to the engineer

This could be about the property, or the people living there. For example, perhaps there’s someone vulnerable living with you, or you need more time to answer the door, or the entrance to your property is at the back of the building.

Your engineer will call when they’re on the way

On the day of your appointment, your engineer will arrive during your appointment slot - not necessarily at the start of it. For example, if your slot is 8am to 12pm, the engineer could arrive at 11:45am, meaning it could go past the time slot you’ve booked. They’ll call in advance to give you a rough arrival time.


We’ll debit the cost from the balance in your Bulb account

You can make a one-off top up payment in your Bulb account if you don't have enough credit to pay for the installation.
