Certified electrical services in London — rewiring, consumer unit upgrades, fault finding, and full installations, delivered by our own qualified electricians from first survey to final sign-off.
Electrical services in London demand a level of care that goes beyond ticking a compliance box — which is why we treat every job, large or small, with the same rigour.
We start with a full assessment of your existing wiring, consumer unit, and circuits. From there our certified electricians propose the safest, most efficient solution, whether that's a full rewire, a consumer unit upgrade, or targeted fault finding — with everything tested and certified on completion.
Every job is quoted in full before work begins — materials, labour, and certification all itemised, with no surprise additions once the job is underway.
Whether it's a single fault fix or a full rewire, every project gets the same process.

Full House RewireConsumer Unit UpgradeElectrical Fit-OutThe cost of electrical services in London depends on the scope of work, the age and condition of existing wiring, and the size of the property — a single fault-finding callout runs very differently to a full house rewire. Rather than quote a generic figure that won't hold up once we see your property, we carry out a free, no-obligation site survey for every enquiry and follow it with one fixed, itemised quote covering materials, labour, and certification.
As a London-based electrical contractor, we work across a wide range of property types — Victorian terraces, new-build flats, and commercial units — each of which brings its own wiring age, load, and safety considerations that a fair quote needs to account for.
Most electrical services in London we complete run from a single day for fault finding and minor repairs up to a week or more for a full rewire or consumer unit upgrade with first and second fix. Timelines depend on the scope agreed at quote stage, access to the property, and whether walls need opening up for cabling. We confirm a realistic schedule with you before work begins, not after.
When comparing companies offering electrical services in London, it's worth checking whether the electricians are certified and registered with a recognised body, whether the quote is fixed or subject to change, and whether workmanship is covered by a guarantee after handover. Grand Home Construction LTD carries out every job with our own certified electricians, provides one fixed quote before work starts, and backs every electrical services in London job with a 10-year workmanship guarantee.
We carry out electrical services in London and the surrounding boroughs, from Victorian terraces to new-build flats. If you're planning a kitchen renovation or full property renovation alongside electrical work, our team can scope both together so the trades and timeline line up from the start.
It depends on the scope of work, the age of existing wiring, and the size of the property. We provide a free site survey and one fixed, itemised quote for every electrical services in London job rather than a generic starting price, since costs vary significantly between a small repair and a full rewire.
Yes. Our own certified electricians carry out every job — this work isn't subcontracted out, so the same team is accountable from start to finish, and every job is tested and certified on completion.
Our team can assess your property and plan the rewire for you, including circuit design and consumer unit specification, as part of the initial consultation. If you already have an electrician's report, we're happy to work from that instead.
Power will be off for parts of the work, particularly during a rewire or consumer unit upgrade, though we sequence work to minimise disruption. We'll agree a realistic timeline with you at quote stage so you know what to expect.
Every electrical services job is covered by a 10-year workmanship guarantee. If something needs attention after handover, we come back and fix it.
Grand Home Construction rewired our entire house safely and efficiently. The electricians were certified, professional, and left everything tested and certified. Highly recommend.Grand HomesProperty Developer
