Key Takeaways

  • 1A consumer unit replacement in Glasgow typically costs between £300 and £550, which is competitive relative to other major UK cities and reflects lower labour overheads in central Scotland.
  • 2Under Regulation 421.1.201 of BS 7671:2018+A4:2026, all domestic consumer units must be a type-tested coordinated assembly housed in a non-combustible (metal) enclosure — this applies equally in Scotland.
  • 3In Scotland, consumer unit replacement is notifiable work under the Building (Scotland) Regulations 2004. It must be carried out by a registered person or notified to the local authority verifier (typically Glasgow City Council).
  • 4BS 7671:2018+A4:2026 requires 30 mA RCD protection for all socket-outlet circuits up to 32 A and for cables concealed in walls at a depth less than 50 mm — covering virtually every circuit in a modern domestic installation.
  • 5Glasgow has a large stock of tenement flats and inter-war council housing in areas such as Govan, Pollokshields, and Maryhill — many still have original consumer units or split-load boards without individual RCBO protection.

Consumer Unit Replacement in Glasgow

Glasgow is Scotland's largest city, with a housing stock ranging from Victorian tenement flats in the West End and Southside to post-war council housing in Castlemilk, Drumchapel, and Pollok. Many properties — particularly tenements and inter-war houses — still have electrical installations that predate current requirements, including rewirable fuse boards and early plastic consumer units.

Under BS 7671:2018+A4:2026, Regulation 421.1.201 requires that consumer units in domestic premises be a type-tested coordinated assembly housed in a non-combustible (metal) enclosure. BS 7671 also requires 30 mA RCD protection for socket-outlet circuits and cables concealed in walls. BS 7671 is the national standard and applies equally in Scotland.

This guide covers everything you need to know about consumer unit replacement costs and requirements in Glasgow — including how Scottish Building Regulations differ from the Part P regime in England and Wales.

Glasgow Consumer Unit Replacement Pricing

Glasgow electricians typically charge day rates of £220 to £300 — among the most competitive of any major UK city. Lower commercial rents, operating costs, and living expenses in central Scotland are reflected in these rates. Most domestic consumer unit replacements in Glasgow are completed within a single day.

Glasgow Pricing Breakdown (2026)

  • Tenement flat (6-way board) — £300 to £400 total. The most common domestic job in central Glasgow. Materials: £110 to £190. Labour: £180 to £200. EIC: £30 to £50.
  • Standard terraced or semi (10-way with RCBOs and SPD) — £380 to £550 total. Materials: £230 to £340. Labour: £220 to £250. EIC and certification: £30 to £50.
  • Larger detached (14-way high-integrity with SPD) — £500 to £780 total. For properties with 12+ circuits, EV charger, or solar PV. Materials: £320 to £480. Labour: £250 to £300. EIC and certification: £30 to £50.
  • Three-phase property — £1,000 to £1,600+ total. Required for larger homes or commercial premises with three-phase supply. Materials: £420 to £700. Labour: £380 to £500. EIC and certification: £50 to £80.

Areas within the Glasgow city centre (G1 to G5) may carry minor parking surcharges. Outer areas such as Paisley, East Kilbride, and Motherwell have similar or slightly lower rates. Always obtain at least three itemised quotes.

When Is a Consumer Unit Replacement Needed?

In Glasgow, these warning signs are particularly common across the city's tenement stock and older inter-war housing:

  • Rewirable fuses (BS 3036) — still found in many pre-1970s Glasgow tenements and council houses. These provide no RCD protection.
  • Plastic consumer unit — Regulation 421.1.201 of BS 7671 requires non-combustible (metal) enclosures. Plastic enclosures are a fire risk in the event of an internal arc fault.
  • No RCD protection — BS 7671 requires 30 mA RCD protection on socket circuits and concealed cables. A board without RCDs or RCBOs is a significant electric shock hazard.
  • EICR C1 or C2 observation — under the Housing (Scotland) Act 2006 Repairing Standard, Glasgow landlords must ensure the electrical installation is safe. A C1 or C2 observation triggers mandatory remedial work.
  • Adding new circuits — EV charger, loft conversion, kitchen renovation, or solar PV requiring additional consumer unit capacity.

Scottish Building Regulations for Consumer Unit Replacement

Scotland has its own building regulations framework under the Building (Scotland) Regulations 2004, which is administered separately from the Part P regime in England and Wales. Consumer unit replacement is notifiable work in Scotland.

  • Notifiable work — consumer unit replacement must be notified to Glasgow City Council's Building Standards department (as local authority verifier) before work begins, unless the work is carried out by a registered certifier.
  • Registered certifiers — electricians registered under the Scottish Certifier of Construction (Electrical Installations) scheme can self-certify their work. SELECT-registered and NICEIC-registered electricians may hold this certification — always verify with your individual electrician.
  • Electrical Installation Certificate — an EIC must be issued for the consumer unit replacement under BS 7671. This documents the design, construction, inspection, and testing of the installation and must be retained by the property owner.
  • BS 7671 applies in Scotland — whilst building regulations differ, BS 7671:2018+A4:2026 is the national standard for electrical installations and applies equally in Scotland. All requirements for non-combustible consumer unit enclosures (Regulation 421.1.201) and RCD protection requirements apply.

For landlords in Glasgow: the Housing (Scotland) Act 2006 Repairing Standard requires that electrical installations in private rented properties be safe and in proper working order. Disputes are handled by the First-tier Tribunal for Scotland (Housing and Property Chamber), not the local council.

What to Expect During a Consumer Unit Replacement

Here is what happens during a typical consumer unit replacement in a Glasgow property:

  • Step 1: Survey and isolation — circuits are identified, the mains is isolated at the DNO cutout, and all power to the property is switched off.
  • Step 2: Remove old board — the existing consumer unit is disconnected and removed. Ageing cables or earthing issues may be identified.
  • Step 3: Install new consumer unit — a new metal consumer unit is mounted, fitted with RCBOs and SPD, all circuits reconnected and labelled.
  • Step 4: Testing — all circuits are tested to BS 7671: insulation resistance, earth fault loop impedance, RCD trip times, and polarity checks.
  • Step 5: Certification — the electrician completes the Electrical Installation Certificate and submits the relevant Scottish building warrant notification.

How Long Does a Consumer Unit Replacement Take?

A standard consumer unit replacement in a Glasgow property typically takes 4 to 6 hours.

Standard Replacement

Like-for-like replacement with adequate wiring and earthing. 4 to 6 hours. Common in post-1970s Glasgow housing and modern flats.

Complex Replacement

Where earthing requires upgrading, meter tails need replacing, or cables require extending. 6 to 10 hours. Common in Glasgow Victorian tenements with original rubber-insulated wiring.

Choosing an Electrician in Glasgow

Glasgow has a large pool of qualified electricians. Here is what to look for when selecting one for a consumer unit replacement:

  • SELECT or NICEIC/NAPIT registration — verify the electrician holds the appropriate Scottish certification to self-certify notifiable electrical work.
  • Itemised quote — materials, labour, certification, and VAT should all be listed separately. Avoid single-figure quotes.
  • EIC included — confirm the Electrical Installation Certificate and building regulations notification are included in the price.
  • Experience with tenement properties — tenement flats in Glasgow present specific challenges including communal earthing systems and limited cupboard space. Choose an electrician with relevant local experience.
