North Mayfair is W1K, the grid between Oxford Street and Berkeley Square and from Park Lane to Davies Street. Hotels, galleries, private offices and some of London’s most sought-after flats line Grosvenor Square, Mount Street and South Audley Street, and Fix It London provides same-day IT support and computer repair to all of them. When a Brook Street concierge desk loses its printer, a Mount Street gallery cannot open its catalogue or a Green Street resident has a MacBook that will not switch on, we send an engineer the same day.

E14 stretches from the towers of Canary Wharf down through Millwall and Cubitt Town to Island Gardens, and north to Poplar, Limehouse and Blackwall. Fix It London sends engineers across the whole postcode, often the same day, whether for a MacBook with spilt coffee on Westferry Road, a Limehouse home office whose video calls keep freezing, or a Poplar desktop that will not start.

W2 stretches from Paddington station across Bayswater and Lancaster Gate to Westbourne Grove, with the Hyde Park Estate and the edge of Little Venice thrown in. A student in a Queensway studio with a laptop that will not charge, or a hotel on Inverness Terrace whose front-desk computer has died mid-check-in, can have a Fix It London engineer on the doorstep the same day.

WC1 covers Bloomsbury, Holborn, the southern side of King’s Cross and St Pancras, and the streets around Russell Square and the British Museum. It is a district of offices, universities, hospitals and hotels, with residential pockets in the mansion blocks and Georgian squares. Fix It London supports businesses and residents across WC1, from a small agency on Theobalds Road with a dead file server to a flat on Marchmont Street with a MacBook that has met a cup of tea.
