Central London
A complete Central London property solution
Rather than a plumber for one job and an electrician for the next, SOS gives you one trusted point of contact and a network of experienced specialists behind it, covering every trade a property needs, from a single repair to a full refurbishment. It's built for homeowners, landlords, managing agents, businesses and commercial property owners alike, so whoever you are, there's one number to call rather than several.

What is SOS?
SOS is a single point of contact that appoints the right accredited specialist, electrician, gas engineer, plumber or builder, and stays accountable for the outcome from first call to handover. Our specialists are experts in their individual trades, holding the qualifications, registrations and accreditations required for the work they undertake. Together, they bring experience across residential, commercial, retail and hospitality settings throughout London.
Every engineer and contractor we appoint holds the registration required for their trade: Gas Safe, NAPIT or NICEIC, and the equivalent for every other trade we cover. Only accredited people are appointed to site, whichever address that happens to be.
