The W1W postcode takes in the western half of Fitzrovia, from Great Portland Street and Great Titchfield Street across to Cleveland Street, with Oxford Street at its southern edge. It is a district of showrooms, studios and media firms, with flats above. When a studio on Mortimer Street finds its shared drive has vanished the morning a pitch is due, or a tenant on Riding House Street cannot get a replacement router to connect, Fix It London sends an engineer out the same day.

W1U is the Marylebone postcode, running from Marylebone High Street and Chiltern Street across to Baker Street and the Portman Estate around Manchester Square. A practice manager on Wimpole Street whose reception PC has locked up before morning appointments, or a resident in a Blandford Street flat whose MacBook took a glass of wine the night before, gets the same answer from Fix It London: an engineer on the way, usually that day.

Fitzrovia’s W1T runs from Oxford Street up to Fitzroy Square and from Tottenham Court Road west across Charlotte Street and Goodge Street, under the BT Tower. Media agencies, architects, start-ups and the restaurants of Charlotte Street share it with mansion flats, council blocks and converted townhouses, and Fix It London provides same-day IT support and computer repair across all of it. A start-up on Whitfield Street with a laptop that will not boot before a demo, or a resident on Cleveland Street whose iMac has frozen with the family photos inside, gets an engineer today.

W1S is east Mayfair: Old and New Bond Street, Savile Row, Cork Street and Hanover Square. Jewellers, galleries, bespoke tailors and fashion houses trade here alongside agencies and offices, with flats on the upper floors, and Fix It London provides same-day computer repair and IT support throughout. A tailor’s cutting room on Savile Row with a pattern PC that will not boot, a Cork Street gallery whose Mac has lost its image library, or an office on Conduit Street with a laptop that died before a pitch: each one gets an engineer today.

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.

W1J covers the southern half of Mayfair, from Piccadilly and Green Park up to Berkeley Square and from Hyde Park Corner along Park Lane to Curzon Street and Shepherd Market. Grand hotels, members’ clubs, galleries and family offices sit beside flats and townhouses, and Fix It London provides same-day IT support and computer repair to all of them. Whether a Curzon Street office has a laptop that will not join the Wi-Fi or a Half Moon Street resident has dropped a MacBook, an engineer can be at the door today.

W1H is south-west Marylebone, from Marble Arch up through Portman Square, Bryanston Square and Montagu Square to the east side of Edgware Road. Mansion blocks, Georgian squares, hotels and head offices sit beside the cafés of Edgware Road and Seymour Place, and Fix It London delivers same-day computer repair and IT support to all of them. A hotel back office on Great Cumberland Place with a dead reception PC, or a Gloucester Place flat where the broadband reaches one room: both get an engineer today.

W1G is Marylebone’s medical quarter, centred on Harley Street and Wimpole Street and reaching to Cavendish Square. Behind the Georgian front doors are private practices, dental surgeries and clinics, with flats on the upper floors, and Fix It London provides same-day IT support and computer repair for all of them. When a practice management PC on Harley Street will not start before the first patient, or a resident on Welbeck Street has lost access to years of family photographs, we send an engineer the same day.
