Does Your Fuse Box Need Replacing?

You probably need a new consumer unit if any of these sound familiar:

Your EICR came back unsatisfactory — C1 or C2 codes on the fuse board must be fixed before the report can pass. Landlords have 28 days.
Rewireable fuses or no RCD protection — old-style boards offer little protection against electric shock or fire.
Circuits keep tripping — nuisance tripping usually means the board can’t cope or a fault is developing.
Burning smell, buzzing or scorch marks — stop using the affected circuit and call us today.
You’re adding an EV charger, electric shower or heat pump — older boards often don’t have the capacity or the right protection.
Your board is 20+ years old or plastic — not automatically dangerous, but likely behind current safety standards. We’ll tell you honestly if it can stay.

Not sure? Send us a photo — we’ll tell you straight whether it needs replacing or not. We regularly tell customers their board is fine. That honesty is why people come back to us.

Every job includes: full disconnection and safe isolation, new board fitted and labelled, dead and live testing of every circuit, Building Regulations Part P notification, and your Electrical Installation Certificate issued the same day — the document your insurer, mortgage lender or letting agent will ask for.

If testing uncovers pre-existing wiring faults, we’ll show you the issue, explain your options and agree any extra cost before continuing — never after.

Landlords: Failed EICR? We’ll Get You Compliant in Days, Not Weeks

  • EICR inspection with report in 24 hours
  • Fixed quote for any remedial work, including consumer unit replacement
  • All work certified and documents sent directly to you or your letting agent
  • Free reminder before your next EICR is due

Frequently Asked Questions

How much does a fuse box replacement cost in Northampton?
Most homes fall between £495 and £845 depending on the number of circuits and the level of protection you choose. Send us a photo of your current board and you’ll have a fixed written price within 2 hours.
How long does it take?
Almost every domestic consumer unit replacement is completed in a single day, with power off for roughly 4–6 hours.
Do I legally have to replace a plastic fuse box?
No — not automatically. If it’s in good condition and passes inspection, it can stay. We’ll give you an honest assessment, not a sales pitch.
What’s the difference between RCD and RCBO boards?
A dual-RCD board groups circuits together — one fault can knock out half the house. An RCBO board protects each circuit individually, so a faulty outdoor light won’t kill power to your fridge. It costs around £150 more and it’s what we’d fit in our own homes.
Will I get a certificate?
Yes — an Electrical Installation Certificate issued the same day, plus Building Regulations notification through NAPIT. This is what mortgage lenders, insurers and letting agents require.
Which areas do you cover?
Northampton, Kettering, Corby, Wellingborough, Milton Keynes and surrounding villages.
