Local to you ## Electrical work across Hertfordshire Hertfordshire is one of the most varied counties we work in. It runs from the post-war new towns of Stevenage, Hatfield and Welwyn Garden City through to the first Garden City at Letchworth, the Georgian streets of St Albans, and the market towns of Hertford, Hitchin, Baldock and Royston. Each has its own mix of housing ages and electrical quirks, and we've built our business around understanding that mix rather than treating every job the same. The new towns mean a lot of 1950s to 1970s council and private estate wiring, some of it updated over the decades and some of it still running on rewirable fuses or ageing consumer units that fall well short of current BS 7671 requirements. The older market towns bring different problems: Victorian terraces and Georgian townhouses with lath-and-plaster ceilings, lead-sheathed or rubber-insulated cabling long past its working life, and period features that need a careful, tidy approach to first-fix and chasing. On top of the domestic stock, Hertfordshire has a strong commercial and industrial base around the A1(M) corridor, business parks in Stevenage, Welwyn Garden City and Hatfield, and warehousing serving the wider South East. We work across both sides of the business, domestic rewires and fuseboard upgrades on one visit, LV panel board installation or commercial lighting on the next, and we scale the team up for larger projects, having run crews of over 25 on major works. Alongside the housing stock, Hertfordshire's geography shapes the kind of calls we get. Towns like Knebworth and Royston sit on quieter rural fringes with larger plots, older barn conversions and outbuildings that often need separate supplies and outdoor circuits. St Albans combines Roman and Georgian heritage with leafy commuter suburbs, while Letchworth's planned Garden City streets bring their own early-20th-century housing quirks. We treat each town on its own terms rather than applying a single template across the county. Whether you need a single fault found in a Hertford cottage, a full rewire in a Stevenage semi, or a new distribution board in a Baldock warehouse, we bring the same NICEIC-approved standard and the same guarantee to every job across the county. Whatever part of Hertfordshire you're in, we bring the same NICEIC-approved standard and the same guarantee to every quote. ### At a glance - NICEIC Approved Contractor working right across Hertfordshire - 20 years' experience with new-town, Victorian and Georgian housing stock - Domestic and commercial work, from single sockets to LV panel boards - £10m public and £10m employers' liability insurance - Free quotes: small jobs from photos, larger jobs from a site visit - 12-month workmanship guarantee on every job Services ## Electrical services across Hertfordshire We cover the full range of domestic, commercial and testing work needed in a county with such mixed housing and business stock: here's what we do most often. ### Domestic Electrical Work From new-town semis to Georgian townhouses, we handle everything from a single faulty socket to a full electrical upgrade for Hertfordshire homeowners.
