Consumer Unit Upgrades in Hemel Hempstead

Your consumer unit is the part of the installation that protects everything else. Thomsett Electrical replaces fuse boards and consumer units across Hemel Hempstead and the HP1, HP2 and HP3 postcodes and we test the circuits before we change anything.

Why boards get changed in Hemel Hempstead

Hemel is largely a post war new town, so a lot of the housing was wired in the 1950s and 1960s. Rubber and early PVC cable from that era is well past its life and many of the boards are still rewireable fuses or early plastic units.

Hemel’s new town housing very often still has the original board and it is usually the first thing an EICR picks up.

Signs your board is due

• Rewireable fuses or an old plastic board with no RCD
• Breakers that trip for no obvious reason
• No spare ways left for a kitchen, an extension or an EV charger
• Scorching, buzzing or a burning smell at the board
• An EICR that has come back with C2 codes against the board

We test before we swap

Fitting a new board onto an installation that has faults in it just moves the problem. A modern unit is far more sensitive, so old faults that used to sit there quietly start tripping it.

We test the circuits first. If something needs putting right we tell you before the board goes in, with a price, so the job is done once.

What you get

A new consumer unit with the correct protection on every circuit, surge protection where it is needed, a clear board schedule and full certification. Most changes take half a day to a day.

Common questions

How long does it take?

Usually half a day to a day. If remedial work is needed first it can take longer and we will have told you that before we start.

Will the power be off?

Yes, for most of the day. We plan the timing with you so it causes as little disruption as possible.

Do I get a certificate?

Yes. Changing a board is notifiable work and we are NAPIT registered, so you get the certificate and the notification.

My Hemel house was built in the 1950s. Does it need a rewire?

Very likely, if it has never been done. Wiring from that period is usually at the end of its life. We test first and tell you whether a full rewire or a partial is the sensible call.
