A consumer unit upgrade is primarily a safety improvement, but it can also have a meaningful impact when it comes to selling your property or remortgaging. Here’s what you need to know.
The honest answer
A new consumer unit is unlikely to directly increase the asking price of your home in the way a kitchen renovation or extension might. What it does do is remove a potential obstacle at a critical point in the sale process.
Electrical condition is one of the things that mortgage lenders, surveyors, and buyers pay close attention to. An outdated consumer unit, particularly one with rewireable fuses, a plastic enclosure, or no RCD protection, can flag concerns that slow a sale down, reduce an offer, or in some cases stall a mortgage application altogether.
Electrical Installation Condition Reports (EICRs) and property sales
It’s increasingly common for buyers to request an Electrical Installation Condition Report (EICR) as part of their due diligence, particularly on older properties. If that EICR returns a C2 for your consumer unit, meaning it’s considered potentially dangerous, the buyer’s solicitor or mortgage lender may require it to be addressed before the sale can proceed.
Dealing with this at speed, under pressure, and often to the buyer’s timeline, is a stressful and expensive way to handle something that could have been sorted beforehand. Having a modern, compliant consumer unit in place means one less thing for a surveyor or buyer to flag.
What buyers and their solicitors look for
Beyond the consumer unit itself, buyers and their representatives are increasingly aware of what a modern installation should include. Specifically:
- RCD protection on all circuits
- A metal-clad, fire-rated enclosure (required since Amendment 3 of the Wiring Regulations in 2016)
- A valid EICR carried out within the last ten years, or five years for a rental property
- Clear circuit labelling and a tidy installation
A consumer unit upgrade that ticks all of these boxes, paired with an up-to-date EICR, puts your property in a strong position from an electrical compliance standpoint.
What about remortgaging?
Mortgage lenders are also becoming more thorough in their valuation assessments. An outdated electrical installation can prompt a surveyor to flag remedial work as a condition of the mortgage offer. Having an upgrade already in place removes that risk.
Is it worth doing before you sell?
If your consumer unit is genuinely outdated, old fuses, plastic enclosure, no RCD protection, then upgrading before you market the property is a sensible move. It’s a finite, known cost (most domestic upgrades fall in the range of £750 to £1050) compared to the unpredictable cost of negotiating it mid-sale.
If your unit is relatively modern and an EICR has returned a clean result, there is no pressing reason to upgrade purely for sale purposes.
As always, the most straightforward way to know where you stand is to get an EICR carried out. It tells you clearly what, if anything, needs attention before you go to market. Get in touch if you’d like to arrange one..
