Consumer Unit & Fuse Board Upgrades in Harrow
Your consumer unit, still often called the fuse board, is the heart of your home's electrics, and plenty of Harrow homes are still running old boards that no longer meet today's standards. Older units, particularly the plastic and rewireable-fuse boards common in the borough's post-war semis, may not cut the power fast enough when a fault happens, which is exactly when you need them to.
A modern consumer unit gives every circuit its own protection, so a fault on one does not plunge the whole house into darkness, and it guards against electric shock and fire. We supply and fit good-quality boards across Harrow, from North Harrow to Wealdstone and Rayners Lane, test every circuit first so any hidden faults show up before the upgrade, and give you the Electrical Installation Certificate to prove the work is safe.
Tested first
We check your circuits before the upgrade, so any hidden faults show up early rather than after the new board goes in.
Protection on every circuit
Each circuit gets its own safety switch, with surge protection available for sensitive electronics.
One-day job
Most upgrades are done in a single day, with the power off for only part of it, and left neatly labelled.
Your questions, answered
How long does a consumer unit upgrade take?
Most are done in a single day, with the power off for only part of that time. We test every circuit as part of the work, so the board goes in on a sound installation.
Why does my new board keep tripping?
A modern board is more sensitive, so it catches faults an old board ignored. That is a good thing, it means a problem is being found. We test every circuit, so anything it flags is sorted out properly.
Do I get a certificate?
Yes. You get an Electrical Installation Certificate so you have proof the work is safe and to standard. As a NAPIT-registered firm we notify any notifiable work as well.
