Electrical design drawings in Wandsworth

Houses, gardens and wiring that has to keep up

31.4 per cent of Wandsworth households live in a house and 42.5 per cent are owner-occupiers. Terraced homes average £970,844, and owners at that level tend to take on a loft, a basement or a wraparound extension in one go, with a kitchen island, underfloor heating and a charger in the same project.

Domestic gardens cover 21.5 per cent of the land, and rear studios are common. We draw the supply as a separate armoured circuit with an isolator at each end, and mark depth and route so the garden is not dug twice.

The borough's guidance is the Housing SPD (covers rear extensions, basements, roof extensions and loft conversions). A basement brings pumped drainage, and the pump circuit and alarm sit on our sheet.

Planning record, heritage and visible items

Officers decided 977 householder applications in the latest year, granting 91.9 per cent, and 360 lawful development certificate applications were made. A clear electrical layout does not decide an application, but it makes the supporting energy and building control submissions straightforward.

The borough has 46 conservation areas and 312 listed building entries. Fittings on a conservation-area frontage, such as a meter box, charger or solar array, are the visible part of the electrical work. Our architectural drawings in Wandsworth page lists the designations.

A house project from brief to issue

A Wandsworth client usually arrives with a long list: an extended kitchen, a loft, perhaps a basement, a charger and a better heating system. We turn the list into a load schedule, with every circuit named and sized, before drawing a single socket.

The drawing then follows. Power and lighting plans show every outlet and switch, the schematic shows how the board is arranged, and the schedule lists each fitting and the lighting figure it meets. We mark the positions of smoke and heat alarms, the thermostat and any controls for underfloor heating, and a note records which parts of the existing installation we kept.

A second technologist then checks the set against the architectural plans: no switch behind a door, no downlight on a beam, no socket where the island will stand. The electrician receives a plan to price and to build from, and the energy assessor receives the lighting and heating facts the council asks for.

Basements deserve one more line. A lower-ground floor with a pump, a dehumidifier and a bathroom adds loads that run all day, and the supply has to carry them without tripping. We show each as a named circuit, label the pump alarm and keep the pump on a way that nobody switches off by accident.

National rules and what we issue

Part P work must be certified within 30 days, fixed lighting must reach 75 lumens per circuit watt now and 105 later, and a new dwelling needs a charge point of at least 7 kW.

We issue a plan per floor, a schematic and a schedule, checked by a second technologist. The set joins your building regulations drawings in Wandsworth and construction drawings. The electrical design drawings hub lists the full service.
