What do the MCA Electrical businesses offer?

The four publicly traceable UK entities share a name but serve different regions and client types. The comparison below covers the key dimensions you need to decide quickly.

Comparison chart of MCA Electrical UK companies

MCA Electrical Services Ltd was incorporated on 15 February 2019 and carries SIC codes 33140 (repair of electrical equipment) and 43210 (electrical installation), confirming the scope of its registered trade activity.

MCA Electrics Limited has a longer company history on record and a registered office in the Belfast region, making it the natural first call for clients in Northern Ireland who need a formally registered contractor.

The Glasgow listing on MyJobQuote is the most service-specific of the four, naming Part P compliance, EICR inspections, and PAT testing among its offered work — useful signals for homeowners who need a condition report or appliance test.

The Ballymena Facebook listing is the thinnest profile of the group. Its value is purely practical: direct phone and email contact details are visible without needing to submit a quote request.

Pro Tip: Cross-reference any trades listing against the Companies House entry using the registered company name. A legitimate limited company will have a matching registered office address and an active status — two details that take under a minute to confirm.

How do you verify and choose the right MCA Electrical contractor?

Before committing to any electrician, run through this short checklist:

  • Confirm the company is registered at Companies House (for limited companies) and that the status shows as active.
  • Ask for proof of public liability insurance — a minimum of £2 million cover is standard for domestic work; commercial jobs typically require more.
  • Request a written, itemised quote before any work begins.
  • Check trade membership: NAPIT and NICEIC are the two main UK competent-person schemes for electricians. A registered member can self-certify notifiable work under Part P of the Building Regulations.
  • Confirm the electrician will issue a completion certificate or EICR on finishing the job — this is a legal requirement for notifiable electrical work in England and Wales.
  • Verify that the trades listing and the legal entity match: the name, address, and registration number should be consistent across all sources.

Questions to ask when you call or request a quote

  1. Can you provide your public liability insurance certificate before starting?
  2. Are you registered with NAPIT, NICEIC, or another Part P competent-person scheme?
  3. Will you issue a completion certificate or EICR on completion?
  4. What is the written quote process, and will it itemise parts and labour separately?
  5. What is your estimated timescale for this job, and what happens if additional faults are found?
  6. Do you carry professional indemnity cover for design or specification work?

Typical cost ranges and timescales

These are ballpark estimates only — always obtain a written quote before agreeing to work:

  • Consumer unit replacement: £300–£600 for a standard domestic board; allow half a day to a full day on site.
  • EICR (Electrical Installation Condition Report): £150–£300 for a typical three-bedroom home; results in a pass or a list of coded observations.
  • PAT testing: £1–£3 per item for a small batch; bulk commercial testing is usually priced per session.
  • Full domestic rewire: £3,000–£6,000 depending on property size; typically two to five days on site.

Prices vary by region, complexity, and contractor. A Bristol-based firm such as MCA Electrical Services Ltd may price differently from a Glasgow or Ballymena tradesperson.

Red flags to avoid: no written quote, cash-only with no receipt, refusal to provide a completion certificate, no verifiable trade membership, and a registered address that does not match the Companies House record.

Did you mean MCA as a technical electrical term?

MCA stands for Minimum Circuit Ampacity. It is the calculated minimum conductor ampacity for equipment containing hermetic motor compressors and appears on the equipment nameplate. According to ExpertCE, MCA is used to size the supply conductors, while MOP (Maximum Overcurrent Protection) sets the upper limit for the overcurrent protection device.

  • MCA governs wire sizing: the supply conductors must be rated at or above the MCA value.
  • MOP governs breaker sizing: the overcurrent protection device must not exceed the MOP value.
  • FLA (Full Load Amperes) is the steady-state running current; MCA is typically higher because it accounts for motor-starting conditions.

Per ETEM Engineering, the standard formula is: MCA = (largest compressor RLA × 1.25) + sum of other FLAs. MCA values are listed on the equipment nameplate alongside MOP, and installers must respect both when sizing conductors and protection devices.

If you need help interpreting a nameplate, share the MCA, MOP, and FLA values with a qualified electrician or consult the equipment manufacturer’s installation guide.

Why we compiled this shortlist

Checking Companies House and cross-referencing trade listings took under an hour, yet it surfaces the facts most people spend far longer hunting for. The single most practical habit you can build when hiring any electrician is to request and store the compliance paperwork — the written quote, the completion certificate, and the EICR — before you make final payment. Those three documents are your evidence if a fault is disputed later.

For operations teams managing electrical maintenance across multiple sites, keeping that paperwork in a central, searchable system matters more than most people realise. Fullyops’s field service software for electricians and its inspection checklist tools are worth reviewing if you manage repeated contractor visits at scale.

Fullyops: a different approach for teams managing electrical maintenance

If you manage electrical maintenance across multiple sites or a fleet of assets, hiring a single local electrician is only part of the picture. Fullyops gives operations teams a structured way to issue work orders, track contractor visits, store compliance certificates, and schedule preventive maintenance — all in one place, without relying on email threads or paper records.

Technician performing electrical equipment maintenance

Where the MCA Electrical businesses above serve individual jobs and local clients, Fullyops suits facilities managers and maintenance contractors who need real-time visibility across recurring electrical work. Tiered plans cover technician, admin, and manager roles, so the right people see the right information at each stage of a job.

FAQ

What does MCA stand for in electrical work?

MCA stands for Minimum Circuit Ampacity. It is the minimum rated ampacity the supply conductors must carry for equipment with hermetic motor compressors, as listed on the equipment nameplate.

What is the difference between MCA and MOP?

MCA sets the minimum conductor size; MOP (Maximum Overcurrent Protection) sets the maximum rating for the overcurrent protection device. Both values appear on the equipment nameplate and must be respected independently.

What is the difference between MCA and FLA?

FLA (Full Load Amperes) is the steady-state running current of the motor.

How do I confirm which MCA Electrical company is the right one?

Search the company name on Companies House using the registration number (11829903 for Bristol; NI048373 for Northern Ireland) and confirm the registered address matches the trades listing you found. For unregistered sole traders, check NAPIT or NICEIC membership instead.

Is MCA Electrical registered with a trade body?

The Companies House entries for MCA Electrical Services Ltd and MCA Electrics Limited confirm legal registration, but trade body membership (NAPIT, NICEIC) is not publicly listed for either entity. Ask directly for membership evidence before hiring.
