How Long Does MCS Certification Take and What Does It Cost?
One of the first questions solar entrepreneurs ask is: how long will MCS take and what will it cost?
It’s a reasonable question – MCS certification is the gateway to residential solar work, and the timeline directly affects when you can start trading commercially.
Here’s a realistic answer, not a sales pitch from a certification body.
Realistic Timescales
The MCS certification process involves multiple stages, each with its own timeline:
Stage 1: Pre-Application Preparation (2-8 weeks)
Before applying, you need:
– Solar-specific training completed (City & Guilds 2399 – typically 3-5 days plus assessment period)
– Quality management system (QMS) documented
– Insurance in place
– Electrical competent person scheme registration confirmed
The main variable: how quickly you can complete training and write your QMS. If you’re booking training from scratch, popular courses can have 4-6 week waiting lists.
Stage 2: Application Processing (2-4 weeks)
Once you submit your application to a certification body (NICEIC, NAPIT etc.), they conduct a desktop review of your documentation. Most certification bodies aim to complete this within 2-4 weeks, but processing times vary.
Stage 3: Site Inspection (1-3 weeks to arrange, 1 day to complete)
Your certification body will want to inspect an installation – either a real completed job or a supervised demonstration. You need to have a job ready (or a willing partner to host a demonstration install).
The main bottleneck: finding your first job to demonstrate on, before you’re certified. Some solar training providers offer demonstration facilities. Some certification bodies accept a witnessed test installation. Discuss this with your chosen certification body before you start.
Stage 4: Certification Issued (1-2 weeks)
After a successful site inspection, certification is typically issued within 1-2 weeks.
Total realistic timeline: 8-20 weeks
The wide range reflects how prepared you are when you start. Someone with existing electrical competent person registration, who has already completed C&G 2399, and who can write a QMS quickly, can achieve certification in 8-10 weeks. Starting from scratch with no training booked: allow 16-20 weeks minimum.

| Starting from scratch (including electrical) | £5,000-£15,000+ |
Ways to Reduce Costs and Timeline
Existing electrical registration – if you’re already registered with NICEIC or NAPIT, your certification body relationship is already established. Solar MCS can often be added to an existing registration more quickly and cheaply than a standalone application.
Combined training courses – some providers offer combined solar + battery storage courses that are cheaper than booking separately.
MCS mentoring schemes – some established MCS installers offer mentoring to new entrants, where you work under their MCS number while building your own certification. This lets you trade immediately while going through the certification process. Ensure the arrangement is properly structured and compliant with MCS rules.
Write your QMS yourself – it doesn’t need to be complex. MCS and your certification body provide templates. A DIY QMS is perfectly acceptable; it just needs to document your processes clearly.

Frequently Asked Questions
Can I trade as a solar installer before MCS certification is complete?
Technically yes – you can install solar PV without MCS certification. But your customers cannot access the Smart Export Guarantee, which makes most residential customers unwilling to use an uncertified installer. Commercial installations where SEG isn’t needed are more viable during this period.
Is there a faster route to MCS certification?
The fastest realistic route is 8-10 weeks for an already-qualified electrician with existing competent person registration who books training immediately. There are no shortcuts to the substantive requirements.
Do I need to renew MCS certification every year?
Yes. Annual renewal involves paying your certification body fee and completing ongoing surveillance requirements (typically site inspections). Failure to renew results in suspension of your MCS number.
What happens if my MCS application is rejected?
The certification body will give you a list of deficiencies to address. Most rejections are for incomplete documentation or QMS gaps – fixable issues. Address the deficiencies and reapply.
