Assess the existing board before selling an upgrade

Consumer unit replacement should follow photographs of the existing board, earthing and circuit layout. Tripping history and previous certificates help. A fixed fuseboard tariff from a postcode is not a safe price basis. Fuseboard upgrades follow board, earthing and circuit evidence. Where cable condition or load requires it, a rewire recommendation replaces a board-only product so certification matches the real installation risk. The accepted written scope states inclusions, exclusions and assumptions. Submitting a private brief is not a booking. Capacity is confirmed after property facts are reviewed. Delivery is in-house when accepted — not a marketplace auction.

Know when a board change is not enough

Poor cable condition, inadequate earthing or overloaded circuits can mean a broader rewire is the safer next step. The written recommendation should say so rather than forcing a board-only product. Fuseboard upgrades follow board, earthing and circuit evidence. Where cable condition or load requires it, a rewire recommendation replaces a board-only product so certification matches the real installation risk. The accepted written scope states inclusions, exclusions and assumptions. Submitting a private brief is not a booking. Capacity is confirmed after property facts are reviewed. Delivery is in-house when accepted — not a marketplace auction.

Confirm space, isolation and access

Modern boards need clear space and safe isolation. Cupboard constraints, meter positions and freeholder rules for common parts should be recorded before attendance is programmed. Fuseboard upgrades follow board, earthing and circuit evidence. Where cable condition or load requires it, a rewire recommendation replaces a board-only product so certification matches the real installation risk. The accepted written scope states inclusions, exclusions and assumptions. Submitting a private brief is not a booking. Capacity is confirmed after property facts are reviewed. Delivery is in-house when accepted — not a marketplace auction.

Keep qualifications and notification on the accepted job

Qualifications and any notification or certification route are confirmed for the accepted electrical upgrade. This hub does not invent company accreditation claims or approval outcomes. Fuseboard upgrades follow board, earthing and circuit evidence. Where cable condition or load requires it, a rewire recommendation replaces a board-only product so certification matches the real installation risk. The accepted written scope states inclusions, exclusions and assumptions. Submitting a private brief is not a booking. Capacity is confirmed after property facts are reviewed. Delivery is in-house when accepted — not a marketplace auction.

Protect occupied homes during changeover

Board changeovers can interrupt power. Occupation, medical equipment dependence and business-from-home needs should be stated so downtime is planned honestly. Fuseboard upgrades follow board, earthing and circuit evidence. Where cable condition or load requires it, a rewire recommendation replaces a board-only product so certification matches the real installation risk. The accepted written scope states inclusions, exclusions and assumptions. Submitting a private brief is not a booking. Capacity is confirmed after property facts are reviewed. Delivery is in-house when accepted — not a marketplace auction.

Separate board upgrades from lighting redesign

New circuits, EV chargers and lighting redesign are separate scopes unless expressly included. Mixing them into an unpriced board visit creates incomplete certification. Fuseboard upgrades follow board, earthing and circuit evidence. Where cable condition or load requires it, a rewire recommendation replaces a board-only product so certification matches the real installation risk. The accepted written scope states inclusions, exclusions and assumptions. Submitting a private brief is not a booking. Capacity is confirmed after property facts are reviewed. Delivery is in-house when accepted — not a marketplace auction.

Programme after capacity and parts clarity

Submitting a brief is not a booking. Parts and board type follow the accepted design. Capacity is confirmed case by case for the full postcode. Fuseboard upgrades follow board, earthing and circuit evidence. Where cable condition or load requires it, a rewire recommendation replaces a board-only product so certification matches the real installation risk. The accepted written scope states inclusions, exclusions and assumptions. Submitting a private brief is not a booking. Capacity is confirmed after property facts are reviewed. Delivery is in-house when accepted — not a marketplace auction.

Compare board proposals by schedule and handover

A comparable proposal lists board type intent, circuit schedule assumptions, earthing works, certification and exclusions. Handover should leave documentation for the accepted upgrade. Fuseboard upgrades follow board, earthing and circuit evidence. Where cable condition or load requires it, a rewire recommendation replaces a board-only product so certification matches the real installation risk. The accepted written scope states inclusions, exclusions and assumptions. Submitting a private brief is not a booking. Capacity is confirmed after property facts are reviewed. Delivery is in-house when accepted — not a marketplace auction.

Frequently Asked Questions

How do I ask for a consumer unit replacement?▼
Use the online form or call 020 7101 3168. Include the postcode, a clear description of the issue or project, photographs where helpful, and access notes. Submission starts a review — it is not a confirmed booking.
Where can I ask for a consumer unit replacement?▼
You may submit for Hampstead, North West London and wider London postcodes. Dedicated pages currently focus on neighbourhoods such as Hampstead, Hampstead Village, Belsize Park, St John's Wood and West Hampstead, with other postcodes reviewed case by case. Coverage and timing are confirmed after the location and scope have been reviewed — not solely because an area page exists.
Who carries out the work?▼
Accepted work goes to Hampstead Renovations or Hampstead Maintenance. We name the skill, registration and insurance the job needs before work starts.
How is the price agreed?▼
The price depends on access, the condition of the building, materials, programme and any approvals needed. Where we can quote, the written document states inclusions, assumptions, exclusions and payment terms. Smaller completed jobs are paid by bank transfer after completion; larger works use the deposit and final terms in the accepted quote.
Do I need a visit before you can quote?▼
Not always. Clear photographs and a written description can be enough for straightforward scopes. Complex fabric, structural openings, concealed services or unclear access usually need a visit before a safe price basis can be written.
What should I send about a flat or a managed building?▼
For flats and mansion blocks, attach any licence-to-alter, working-hours note, riser plan or managing-agent rules you already hold. Lift size, porter rules and communal corridor protection often affect how consumer unit replacement attendance is programmed. Freeholder approval is never invented from a neighbourhood page alone — those facts come from the property documents and the accepted written scope.
Does this work need Building Control?▼
Not always. Whether approval or a competent-person route is needed depends on the defined work and property. Openings, structural alterations, drainage changes and certain electrical or heating works are more likely to need one of those routes. We flag known compliance questions in triage. A service hub does not predict a notification outcome from a neighbourhood page. Attach any existing notice or completion certificate you hold.
Can I submit a consumer unit replacement brief in London?▼
Yes. Send the postcode and job details for review. Submission is not a booking; we confirm whether the brief fits, current availability and the next step.
How is consumer unit replacement work priced?▼
The price depends on the accepted scope, access, timing, materials and any assessment required. We confirm a written quote or other agreed price basis before planned work starts.

People Also Ask About Consumer Unit Replacement

Do I have to replace an old plastic consumer unit?▼

There is no legal duty to. Electrical Safety First's Best Practice Guide 1 states there is no legal requirement calling for an existing installation to be upgraded to current standards, and that a consumer unit need not be replaced simply because its enclosure is made of combustible material such as plastic, or because it does not incorporate RCD protection.

Source: Electrical Safety First, Best Practice Guide 1: Replacing a consumer unit in residential and similar premises, issue 5.2

Do consumer units have to be made of metal?▼

Not necessarily metal, but the enclosure must be non-combustible. BS 7671 regulation 421.1.201 requires a consumer unit's enclosure to be manufactured from non-combustible material, or the unit to be enclosed in a non-combustible cabinet. Electrical Safety First confirms ferrous metal is only given as an example, and that a plastic enclosure fitted with an intumescent seal does not meet the requirement.

Source: Electrical Safety First, Wiring Regulations Help (BS 7671 technical guidance)

Is an EICR a certificate or a report?▼

It is a report, not a certificate. Electrical Safety First states that an Electrical Installation Condition Report provides an assessment of the current in-service condition of an electrical installation against the requirements of the edition of BS 7671 current at the time of the inspection, irrespective of the age of the installation. It must record the extent of, and any limitations on, the inspection.

Source: Electrical Safety First, Best Practice Guide 4, issue 7.4, section 2

Is replacing a consumer unit notifiable building work?▼

Yes, in England. Regulation 12(6A)(b) of the Building Regulations 2010 expressly lists the replacement of a consumer unit as work for which a building notice or an application for building control approval with full plans must be given. The alternative routes are self-certification by an installer registered with a competent person scheme, or certification by a registered third party.

Source: The Building Regulations 2010, regulation 12(6A)(b), legislation.gov.uk

Should I have an EICR before replacing a consumer unit?▼

It is recommended. Electrical Safety First's Best Practice Guide 1 advises that a contractor planning a consumer unit replacement should strongly recommend the customer has an Electrical Installation Condition Report prepared on the installation first. If the customer refuses, a pre-work survey must be undertaken before any work is carried out, to establish whether any immediate or potential danger exists.

Source: Electrical Safety First, Best Practice Guide 1, issue 5.2, section 4 (Reason for change)

What certificate should I get after a consumer unit replacement?▼

An Electrical Installation Certificate. Electrical Safety First's Best Practice Guide 1 explains that replacing a consumer unit is an alteration to the installation, and that on completion of verification an Electrical Installation Certificate must be issued under BS 7671 regulation 644.1, with schedules of inspection, circuit details and test results. In England or Wales the replacement is also notifiable building work.

Source: Electrical Safety First, Best Practice Guide 1, issue 5.2, sections 1, 2 and 5

What do C1 and C2 codes mean on an electrical condition report?▼

Code C1 means danger is present and immediate remedial action is required. Code C2 means potentially dangerous and urgent remedial action is required. Electrical Safety First states that where any observation is given a C1 or C2, the overall condition of the installation must be reported as unsatisfactory. Where only C3 observations, meaning improvement recommended, are recorded, the outcome can be satisfactory.

Source: Electrical Safety First, Best Practice Guide 4: Electrical installation condition reporting, issue 7.4, sections 6 and 7

What must be checked before a consumer unit is replaced?▼

Electrical Safety First's Best Practice Guide 1 says the installer must verify, as a minimum, that the main earthing terminal is connected to an adequate means of earthing, that main protective bonding is adequate, that earthing arrangements suit fault protection, that the meter tails and the distributor's equipment have adequate current-carrying capacity, and that the incoming supply polarity is correct.
