“Replaced three separate apps with Elec-Mate. Certs, quotes, and scheduling all in one place.”

Before you split out labour and materials, you need a clear scope. A full rewire is not just new cable. It usually includes first fix, second fix, accessories, the consumer unit, testing, certification, and making the installation ready for use.
If you need the wider cost context first, the full rewire cost guide is the best place to start. This page focuses on how the price is built up rather than the overall figure alone.
Every key change in the 2026 amendment on one page. AFDDs, TN-C-S protection, new schedule columns, model forms. Pinned on your van dash.
Labour is where experience matters most. Two properties with the same floor area can take very different amounts of time if one has easy access, modern construction, and straightforward routes, while the other has tight voids, damaged plaster, or awkward existing alterations.
Materials can look small on paper and still move the final price a lot once the full list is counted. A rewire with more sockets, lighting points, or a higher-spec finish will naturally carry a bigger materials line than a basic like-for-like replacement.
Professional quotes with the remedial estimator, then invoice from your phone the moment the work is done. From £6.99/mo.

The simplest way to price a full rewire is to estimate the labour separately from the materials, then add any extras that the client has specifically asked for. That gives you a quote that is easier to defend if the job changes partway through.
If a client asks why one quote is higher than another, you want to be able to explain the difference without rewriting the whole job. Labour, materials, testing, and finishing work should all be visible in the final price.
If the installation is complex or the scope is still moving, build the quote in the electrical quoting app so you can adjust the estimate as the survey gets clearer.
Once the work is complete, the invoice should still reflect the same split between labour and materials. That keeps the billing easy to understand and reduces questions after the job is finished.
If you are sending the final bill after a rewire, the electrician invoice app keeps the pricing, job notes, and billing together so you do not have to recreate the job from scratch.
For the wider cost context, the rewire cost UK guide and the consumer unit replacement cost guide are useful companion pages when the client is comparing different options.

Elec-Mate is my go to app for business and electrical work. It's feature rich without feeling cluttered. A true all in one app for quotes, certs, calculations, RAMS, EICRs, and more. I use it every day without fail, and it makes my workflow much smoother since I'm not jumping between apps anymore. The price-to-feature ratio is excellent. Any issues I've had, the developer responds within the hour and usually fixes them the same day. 100% recommend.
I've used the app and the web based version for a while now and it's well worth the investment. If you're an apprentice or experienced Spark give it a go, you won't be disappointed.
I've been using Elec-Mate for a while now, and honestly, it's one of the best apps I've ever downloaded. Every aspect of it feels thoughtfully designed, from the clean and intuitive interface to the powerful features that make everything so easy to manage. It's clear that a lot of care and attention went into building this app, and it shows in every detail.

Keep labour, materials, quote, and invoice aligned so the client sees a clear breakdown and you keep the job easy to defend later.
