Everything below is what an honest, NAPIT-approved contractor will actually do for you, not what a marketing agency thinks sounds good on a website. What it covers Electrical work for new builds, extensions and full renovations, from reading the drawings and agreeing socket / lighting positions with you, through first-fix cabling before plaster, second-fix fitting after decoration, consumer unit uprates, EV charger provision, garden room supplies, and full initial verification and certification when the build is complete. Who it's for Homeowners doing an extension, loft conversion or garden room; developers on single-plot or small-plot new builds; builders wanting a reliable electrical subcontractor who turns up when scheduled; architects and PMs wanting one electrical contractor to hold from first-fix to sign-off. When you need it Ideally at design stage, decisions about circuit layout, EV provision, kitchen socket positions and lighting design are much cheaper made on paper than in plaster. Realistically we're often brought in once the shell is up and the builder needs the first-fix window booked. Why professional matters Electrical work on a new build or extension is a phased job, first fix before plaster, second fix after decoration, and it has to schedule around every other trade without becoming the bottleneck. A NAPIT-registered contractor self-certifies the notifiable work, saving you a separate building control visit and fee. What Happens If You Leave It ## The cost of putting it off. Every one of these is something we see weekly. None of them get better on their own. ### Electrical decisions made too late Retrofitting sockets, downlights or extra circuits after plaster is done doubles the cost and rarely looks as clean. Every position decided post-plaster is a chase into fresh plaster. ### Under-specced consumer unit New extensions frequently need consumer unit uprates, undersized distribution boards can't accommodate the new circuits, forcing an awkward retrofit part-way through the build. ### EV, solar and heat pump provision skipped Provision for EV charging and low-carbon services is trivially cheap during first fix and expensive later. Skipped at first-fix, it becomes retrofit surface conduit two years later. ### Non-notified work fails final sign-off Notifiable electrical work carried out by a non-registered installer requires building control notification and inspection, an avoidable cost, delay and paperwork trail. Our Process ## How the job actually runs, start to finish. 1. Step 1 ### Design review & scope We work off the drawings with you or your builder, agreeing socket positions, lighting design, circuit layout and any EV / low-carbon provision. 2. Step 2 ### Fixed written quote Priced against the actual drawings and scope, never a per-point guess. 3. Step 3 ### First fix Back boxes set, cables run through stud, floor voids and chased where needed, before plaster. 4. Step 4 ### Second fix Faceplates, downlights, feature lighting, extractors, smoke alarms and consumer unit fitted after plaster and decoration. 5. Step 5 ### Test, certify & sign off Full initial verification, Electrical Installation Certificate issued, NAPIT self-certification lodged. Benefits ## Why customers stick with us. ### Priced off drawings, not per point You get a fixed price against the actual scope, not a padded per-point rate. ### Scheduled to your build programme First-fix and second-fix windows agreed with the builder so we're never holding up plaster or decoration. ### Self-notified, no separate building control fee NAPIT registration lets us self-certify notifiable work, saving you time and cost. ### Future-proofed first-fix EV provision, home-working sockets and extra lighting circuits planned in at first-fix, not retrofitted later. ### One contractor from design to sign-off Same electrician on-site through first-fix, second-fix and testing. ### Compliance-ready paperwork Full certification and self-notification lodged, one less thing for your builder or PM to chase. In Detail ## Everything else worth knowing. The specific materials, methods and situations that make this job go well, or badly, depending on who's doing it. [Request A Free Estimate](/contact) ### Extensions, loft conversions and garden rooms Extensions almost always require additional circuits back to the main consumer unit, often triggering an uprate of the board itself. Loft conversions bring notifiable work (smoke alarms interlinked to existing, escape lighting considerations, new circuits). Garden rooms need a properly-sized SWA sub-main from the house, an appropriate consumer unit in the room itself, and RCD protection matched to the outdoor cable route. ### First fix, what actually happens First fix is the phase before plaster: back boxes for sockets and switches set into the wall, cabling run through stud walls and floor voids, cables chased into blockwork or brickwork with the correct depth and clip centres, provision left for downlights and feature fittings, and cable runs labelled. We coordinate with the plasterer so nothing is buried where it can't be traced. ### Second fix and testing Second fix is after plastering and (usually) decorating: faceplates, light fittings, downlights, extractor fans, interlinked smoke and heat alarms, consumer unit fitted or uprated, and the new circuits energised. Full initial verification testing follows: insulation resistance, earth loop, RCD trip time, polarity, all logged on the Electrical Installation Certificate for the property file. ### Residential vs commercial new builds Residential new-build and extension work focuses on layout, decor-friendly finishing and NAPIT self-notification for domestic notifiable work. Small commercial new-build work, coffee shops, salons, offices, light industrial units, brings heavier supplies, DNO applications, containment on show, emergency lighting to BS 5266 and PAT testing at hand-over. We cover the domestic side end-to-end and take on light commercial new builds after a site survey. Recent Work ## Recent new builds & extensions projects.
