Warning Signs

6 Signs You Need A Consumer Unit Upgrade

If you notice any of these in your Glasgow property, your fuse box needs modernising.

Old Fuse Box Or Wylex Board

If your consumer unit still has ceramic fuses, rewireable fuses or a Wylex fuse board, it provides no RCD protection. This is the number one sign you need an upgrade.

Frequent Tripping

Modern consumer units with RCDs are more sensitive to faults — but if your old board trips regularly or refuses to reset, the unit itself may be faulty and need replacement.

Not Enough Circuits

Adding a new kitchen, EV charger or extension but your consumer unit is full? An upgrade with a larger board gives you spare ways for future expansion.

Buying Or Selling A Property

A modern RCD-protected consumer unit is a major selling point and often required by mortgage lenders and surveyors. It also helps pass an EICR.

Burning Smell Or Heat Damage

A hot consumer unit, discoloured casing or burning smell indicates internal damage. This is an immediate safety hazard requiring urgent replacement.

Insurance Or EICR Requirement

Many insurers now require RCD protection. An EICR with C1 or C2 defects on the consumer unit means you must upgrade to maintain cover and compliance.

What's In A Modern Consumer Unit?

Four essential features every upgraded board should include.

RCD Protection

Residual Current Devices detect earth leakage and disconnect power in milliseconds, preventing fatal electric shocks from faulty appliances or damaged cables.

Surge Protection

Surge Protection Devices (SPDs) protect your appliances, computers, TVs and smart home equipment from voltage spikes caused by lightning strikes and grid fluctuations.

Circuit Labelling

Every circuit is clearly labelled with its function and the rooms it serves. No more guessing which breaker controls the kitchen versus the bedroom.

Spare Capacity

Modern boards have more ways than older units, giving you space for future circuits like EV chargers, garden rooms, extensions or solar battery storage.

Consumer Unit FAQs

Common questions about fuse box upgrades in Glasgow.

Consumer unit upgrades in Glasgow typically cost £450-£1,800 depending on the board type and number of circuits. A standard 6-way RCD board for a small flat starts at £450. A 10-way dual RCD with surge protection for a family home costs £650-£950. High-integrity boards for complex properties range from £1,200-£1,800.
Most consumer unit replacements take 1 day. Simple 6-way boards in small flats take 4-6 hours. Larger 10-14 way boards with surge protection take 6-8 hours. Very complex installs with multiple RCDs and circuit modifications may take 2 days. Power is usually off for 4-6 hours during the swap.
Yes, power must be turned off during the replacement. We coordinate the timing to suit your schedule — early morning, mid-morning or afternoon. For Glasgow businesses we work evenings or weekends. Power is typically off for 4-6 hours.
No. A consumer unit upgrade does not require a full rewire. However, if your existing wiring is very old (pre-1960s rubber or lead) we will advise you honestly. In most cases, a new board works perfectly with existing modern PVC wiring.
A single RCD protects all circuits but if it trips, you lose all power. A dual RCD board splits circuits across two RCDs — so if one trips, half your house still has power. For larger properties or those with critical circuits like freezers or medical equipment, dual or high-integrity boards are recommended.
Yes. SPDs protect expensive electronics from voltage surges caused by lightning, grid switching and appliance faults. Given the cost of TVs, computers, gaming consoles and smart home equipment in modern Glasgow homes, SPD protection is excellent value at typically £80-£150 extra.

"After getting a staggering quote from another company for a full rewire I reached out to David based on the Google reviews. I got a quote quickly that I was pleased with, not just because of the price but due to it having such a thorough breakdown."
