EICR Inspection

“I'm based in Colchester and have been trying to find a good electrician that I can trust to complete an EICR on my property, following a bad experience with another company. After initially speaking with Elise for a quote, I felt at ease and the service provided was excellent. Highly professional and trustworthy.”

FAQ

Frequently Asked Questions

Common questions about consumer unit upgrades in Essex

Consumer unit upgrade costs typically range from £400–£800 for a standard property, depending on the size of your property, the type of consumer unit required (standard dual RCD or full RCBO board), and any additional work needed such as new circuits or remedial wiring. We provide free, no-obligation quotes with transparent pricing including all materials, labour, testing, and certification. No hidden costs — ever.
Most consumer unit upgrades can be completed in 3–6 hours. This includes safely isolating the power, removing the old unit, installing the new consumer unit, connecting all circuits, full testing to BS 7671 standards, and providing certification. Your power will be off during the installation, but we work efficiently to minimise disruption. We'll advise you of the expected duration when we provide your quote.
If you have an old-style fuse box with rewirable fuses or old MCBs without RCD protection, it's strongly recommended to upgrade to a modern consumer unit. Current BS 7671 regulations require RCD protection for most circuits, which old fuse boxes don't provide. An upgrade significantly improves electrical safety, is often required for house sales, mortgage applications, and insurance, and is mandatory when carrying out other notifiable electrical work.
A standard dual RCD consumer unit has two RCDs protecting groups of circuits — if one RCD trips, half your circuits go off. An RCBO (Residual Current Breaker with Overcurrent protection) board has individual RCBOs for each circuit, so if one circuit trips, only that circuit is affected. RCBO boards are more expensive (typically £100–£200 more) but offer superior protection and eliminate nuisance tripping. We recommend RCBO boards for most properties and will advise you on the best option for your needs.
Yes, absolutely. All our consumer unit upgrades include a full Electrical Installation Certificate (EIC), detailed test results for every circuit, and Building Control notification under Part P of the Building Regulations. These certificates are essential for insurance, house sales, mortgage applications, and proving compliance with electrical regulations. We provide all documentation as standard with every installation — you'll receive both a physical copy and a digital copy.
Yes, we offer same-day consumer unit upgrades across Essex subject to availability. This is particularly useful for urgent situations such as failed electrical safety inspections, house sale requirements, insurance demands, or safety concerns. Contact us early in the day for the best chance of same-day service. We carry a range of consumer units on our vans to accommodate urgent requests.
Yes, the power supply must be isolated at the meter for safety during the consumer unit upgrade. Your electricity will be off for the duration of the installation (typically 3–6 hours). We recommend planning ahead by charging devices, preparing food in advance, and informing anyone working from home. We'll confirm the expected duration when we book the job so you can plan accordingly.
Not always legally required, but increasingly expected. Many buyers' solicitors and mortgage lenders will flag an outdated fuse box or consumer unit without RCD protection as a condition of sale or mortgage offer. An EICR (Electrical Installation Condition Report) carried out during a house sale will often recommend a consumer unit upgrade if the existing unit is outdated. Upgrading before listing your property can prevent delays and strengthen your sale.
Yes — under the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020, landlords must ensure electrical installations are safe and have a valid EICR. An outdated consumer unit without RCD protection will typically result in a C2 (potentially dangerous) or C3 (improvement recommended) code on an EICR. C2 codes require remedial action within 28 days. We work with many Essex landlords to upgrade consumer units and ensure compliance.
The size of consumer unit you need depends on the number of circuits in your property. A typical 3-bedroom house requires a 10–12 way consumer unit. Larger properties or those with additional circuits (EV charger, solar PV, outbuildings) may need a 16–18 way unit or a split-load board. We assess your existing circuits and any planned additions during the free survey and recommend the most appropriate unit for your property.
A consumer unit upgrade can resolve nuisance tripping caused by an old or faulty RCD, but it won't fix underlying wiring faults or overloaded circuits. Before upgrading, we carry out a full assessment to identify the root cause of any tripping issues. If there are underlying faults, we'll advise you on the remedial work needed alongside the consumer unit upgrade. We always aim to provide a complete, lasting solution rather than just replacing the unit.
We provide consumer unit upgrade services across all of Essex including Chelmsford, Colchester, Basildon, Southend-on-Sea, Brentwood, Harlow, Braintree, Maldon, Witham, Rayleigh, Wickford, and over 50 other towns and villages. We offer fast response times throughout the county with same-day service available in most areas. Contact us to confirm coverage for your specific location.
