Cost factors
Consumer unit replacement costs in the UK depend on home size, number of circuits, and whether an EICR is required.
- Consumer unit replacement (1–3 bedroom home): £500–£800
- Consumer unit replacement (4+ bedroom home): £700–£1,200
- Upgrade to split-load RCD consumer unit: £600–£1,000
- Electrical Installation Condition Report (EICR): £150–£400
- Additional circuit installation: £150–£400 per circuit
- Earthing upgrade (if required): £100–£300
Most electricians include the Part P self-certification notification in their price. Confirm this before accepting a quote — it saves you notifying the building control yourself.
Why do prices vary?
- Number of circuits: More circuits (sockets, lighting, heating, EV charger, solar, etc.) require a larger consumer unit with more ways. Larger units cost more to supply and take longer to wire.
- Old fuse board type: Older rewirable fuse boards (with ceramic fuses) are simple to replace. Some older installations with aluminium wiring or inadequate earthing require additional remedial work.
- EICR requirement: Landlords are legally required to have an EICR every 5 years. Many electricians recommend an EICR before or combined with consumer unit replacement to identify any additional faults.
- AFDD (Arc Fault Detection Device): The 18th Edition IET Wiring Regulations (updated 2022) now recommends AFDDs in certain locations. Adding AFDDs to each circuit increases cost but improves protection against electrical fire.
- Location and access: Consumer units are normally in the hallway, under stairs, or in a utility room. Awkward locations add labour time.
Subsidies & incentives
No UK government grant currently covers consumer unit replacement. However, if an EICR reveals dangerous electrical conditions in a rented property, local councils may require landlords to fund remedial work under the Housing Health and Safety Rating System (HHSRS). Some local authorities offer grants or interest-free loans for safety-related home improvements for vulnerable owner-occupiers — check with your local council. VAT at 20% applies to electrical installation work.

High (+15%)Very high demand for skilled trades — university city with large professional population and premium property expectations.
Housing characteristics in Cambridge
Cambridge combines world-renowned historic architecture with a dense ring of Victorian and Edwardian terraces built for University staff and workers, plus extensive post-war suburban development. The city centre has some of the UK's most significant conservation area protections — any external change to properties in the central conservation areas requires careful planning. The University owns large swathes of residential property under various leasehold arrangements, which can restrict what tenants and leaseholders can do without consent. Cambridge's rapid growth as a technology and biomedical hub has driven property prices and trade day rates to near-London levels, with high demand from a professional population willing to pay for quality outcomes. The flat Cambridgeshire landscape means extensions are straightforward from a groundwork perspective, though clay soil in some areas requires deeper foundations. The market is significant for heat pump retrofits and high-specification kitchen and bathroom renovations, with homeowners investing heavily in energy-efficient upgrades alongside cosmetic improvements.
