If your consumer unit is more than 10–15 years old, contains rewirable fuses, lacks RCD protection, or uses old-style MCBs rather than RCBOs, an upgrade is strongly recommended. A modern RCBO consumer unit provides individual protection per circuit, prevents nuisance tripping and brings your Sleaford home fully up to current BS7671 18th Edition standards.

An RCBO (Residual Current Breaker with Overcurrent protection) combines both overload protection and RCD protection in a single device for each circuit. Unlike older split-load boards, if one circuit trips it only affects that circuit — not half the house. This is the gold standard for consumer unit upgrades and what we install as standard across all Sleaford properties.

A consumer unit upgrade in Sleaford typically costs £400–£700 depending on the size of the board and any additional work required (such as bonding, earthing or defect rectification). We always carry out a pre-installation inspection and provide a fixed written quote before starting. Call 01529 265060 for a free estimate.

Most consumer unit upgrades in Sleaford are completed in a single day. You'll have power to circuits interrupted for a few hours during the installation, but we restore power before we leave. The property remains fully habitable throughout.

Yes — a consumer unit replacement is notifiable under Part P of the Building Regulations. As NAPIT registered electricians, we self-certify all consumer unit upgrades in Sleaford, notifying the relevant local authority on your behalf. You receive your Building Regulations Compliance Certificate within a few weeks of completion.

We always check the existing main and supplementary bonding as part of a consumer unit upgrade in Sleaford. If the bonding is found to be inadequate or absent, we'll include the necessary bonding works within the quote — this is a safety requirement under BS7671 and must be in place for the installation to be certified.

Many insurers now require properties to have up-to-date electrical installations including RCD protection. An RCBO consumer unit upgrade in Sleaford, backed by Part P certification, demonstrates your installation is compliant and can positively affect your insurance position. Keep your certificate safe — you'll need it.

Not necessarily — but if you have an EICR carried out (which most buyers now request), an old consumer unit may generate C2 or C3 observations that could affect the sale. Upgrading proactively is often the best approach for Sleaford homeowners looking to sell, as it removes a potential negotiating point and provides the buyer with confidence in the installation.
