Safe rewiring for homes old and new
Rewiring a house is not a job to leave to chance, and we carry out the full process from the initial survey through to safe installation. Older properties often need new wiring to bring the electrics up to modern standards, especially if sockets, lighting and circuits no longer suit the way you live. If you're planning an extension, a rewire also helps you prepare the space properly before walls and finishes are complete.
We work carefully and explain what needs doing in plain language, so you know where your money is going. You'll find M25 Electrical Contractors Ltd straightforward to deal with, with tidy working practices and pricing that stays clear from the outset. We help you make your property safer, more practical, and ready for everyday use.


A thorough approach from first check to final sign-off
Before any installation starts, we assess the condition of your current wiring and look at how your property is used now. That matters in homes that have been extended over time, because older circuits don't always match newer layouts or modern electrical demand.
Our qualified electricians carry out rewiring work with safety at the centre, backed by City and Guilds qualifications, TrustMark recognition, and membership of the Electrical Contractors Association. We also notify the local authority where required and provide the right certification for completed work. Our team keeps the process organised, which makes a disruptive job feel far more manageable.
