Rewires: the detail

Domestic & Commercial Rewiring Services in Herts, Beds, Bucks & London

Does Your Property Need Rewiring?

If your home or building is over 25 years old and still has its original wiring, it may no longer meet modern safety standards, making electrical rewire in St Albans and Hertfordshire necessary. UK electrical regulations have evolved significantly, and older installations can pose serious fire or shock risks.

Common signs that your property may need rewiring include:

  • Frequent trips in the fuse board
  • Flickering lights
  • Discoloured or scorched sockets
  • Exposed or damaged wiring
  • Receiving small electric shocks from switches Poor test results on an Electrical Installation Condition Report (EICR) are also a strong indicator that rewiring may be required.

Even if everything appears to be functioning correctly, it’s recommended to have inspections every 10 years for owner-occupied homes and every 5 years for rented or commercial properties. If you’re unsure, our qualified electricians can provide an EICR and advise on the best course of action.

What’s Involved in an Electrical Rewire?

An electrical rewire in Hertfordshire involves replacing outdated wiring and components to ensure your system meets modern standards. Our team handles everything from upgrading consumer units to installing modern sockets and switches. We also ensure that all work complies with current safety regulations.

For larger projects, we can install or upgrade other electrical systems such as:

  • Solar panels
  • Smart technology

After the rewire is complete, we’ll provide an Electrical Installation Certificate to certify that the system is safe and fully compliant with regulations. Our team ensures minimal disruption while completing the rewire efficiently, so you can get back to using your property safely.

Questions we’re asked

How long does a rewire take?

A typical three-bedroom house is often a matter of days to a couple of weeks depending on access, plastering and decoration. We give you a programme with the quote.

Can I stay in the house?

Often, yes, though it is simpler when rooms can be emptied. We keep a temporary supply and set up so you always have power for the essentials.

Does a rewire need Building Control?

In England it is notifiable work under Part P. We are registered to self-certify and arrange the notification.
