Consumer Unit Upgrades in Watford

Your consumer unit is the part of the installation that protects everything else. Thomsett Electrical replaces fuse boards and consumer units across Watford and the WD17 to WD25 postcodes and we test the circuits before we change anything.

Why boards get changed in Watford

Watford has a wide mix, from Victorian terraces near the centre to post war estates and a lot of flat conversions. Converted flats are where we see the most tired boards and shared circuits that were never properly split.

Converted flats around Watford often have tired boards and circuits that were split badly when the property was divided.

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.

Do you cover Croxley Business Park?

Yes. We take on commercial installations and maintenance for offices and units across the Watford business areas.
