TrustMark Accredited Solar Installer

TrustMark is the UK Government's only endorsed quality scheme for tradespeople working in and around your home. We're a North Manchester firm, registered under Renegade Electrical Ltd, firm reference 3127838, and you can check that listing on the TrustMark website yourself before you commit to anything.

What the registration actually covers

TrustMark-registered firms are assessed against government standards for technical competence, customer service and trading practices, not on how well they write a brochure. In practice that means:

• work completed to TrustMark's quality standards, with the certification to match
• clear quotes and contracts, with no moving figures halfway through a job
• proper insurance and financial protection arrangements for the work
• access to TrustMark's independent dispute resolution service if something ever goes wrong

The last one matters more than people think. Most solar jobs go smoothly, but when you're letting a firm loose on your roof and your consumer unit, you want to know there's a route that doesn't depend on the installer's goodwill.

Why an electrician's registration carries weight

Ashley Merritt has been a qualified electrician for over 20 years, including more than ten on commercial projects, and he established Renegade Electrical in 2018 before expanding into solar panel installation, battery storage and EV chargers. The TrustMark registration covers that electrical foundation. Alongside it sits MCS certification (NAP-66870), which qualifies your installation for Smart Export Guarantee payments, NAPIT registration (member 66870), and the HIES Consumer Code for consumer protection on the renewable side.

The practical upshot: the person who surveys your roof is the qualified electrician who designs the system, oversees the installation and signs off the certification. The work is done by our in-house team. Scaffolding and roofing are the only parts we outsource, with the roofing done by the same firm for years, and nobody hands your job to a crew you've never spoken to.

What our customers say

"If you want a small company you can trust to give good advice and do a quality job look no further.

We were recommended by a friend and were not disappointed with this small but efficient company. They gave good advice carried out superb work and charged a reasonable price. Our daughter was so impressed they are having the same system installed."

Trustpilot review, June 2026

Reviews like that are earned job by job. TrustMark is the outside check that the same standards - technical competence, customer service and fair trading - are applied to every job, not just the ones a customer writes in about.

Where we work

We're based in North Manchester, around Prestwich and Middleton, carrying out TrustMark-registered electrical work alongside MCS-certified solar and battery installations across Greater Manchester. That mix matters for older North Manchester housing: consumer units, earthing and wiring from past decades all get checked properly before anything new goes on the wall.
