Business in London
London is not a market, it is thirty-three of them, and the differences between boroughs are larger than the differences between most English counties. A regulated firm in the Square Mile, a food producer at Park Royal, a studio in Hackney Wick, a freight forwarder on the Heathrow perimeter and a golf club near Orpington are all London businesses and none of them wants the same thing. Three constraints repeat across all of it: almost nobody owns their building, so what can be installed is somebody else’s decision; conservation and listed status rule out physical work across large parts of the centre and the western suburbs; and leases are short enough that anything tied to an address is a liability. That is why the answer in London is a service far more often than it is an installation. We have no office here and will not pretend otherwise — the capital is covered from Windsor, which borders Hillingdon, and from Worthing for the southern boroughs.

London — common questions
You have no office in London. Why would we use you rather than a London supplier?
A fair question and we would rather answer it than dodge it. There is no director in the capital: it is covered from Windsor, which borders Hillingdon, and from Worthing for the southern boroughs. What that buys you instead is group buying power — a small London business priced inside a national account — and one named person rather than an account queue. If having somebody in the building the same day matters more, a London supplier is the honest answer.
Our London office is leased and we may move in a couple of years. What should we commit to?
Nothing tied to the building, and nothing with a term longer than the lease. That is the single most useful rule in London, where short leases are the norm. Cloud telephony travels with you — the numbers are not tied to an address and handsets re-register wherever you land. Connectivity is the one to watch: match the circuit term to the lease rather than taking a longer one for a better rate.
Do you cover the whole of London?
SCG supplies businesses across the whole UK, so the short answer is yes. The longer and more useful one: we have 2 directors established in Windsor and Worthing, and 41 towns in London have their own page with local detail on them. Outside those, you get the same products and the same support, from someone slightly further away.
Who would I be dealing with in London?
Joshua Littman in Windsor and Nick Thomas in Worthing. The published direct numbers let you speak to a named regional contact. They coordinate your requirements with the Southern Communications Group's service teams; support arrangements depend on the services and scope you agree.
We have sites across London. Can they run as one system?
Yes, and multi-site is where this arrangement is worth most. One cloud phone system spans every site with internal dialling between them, one bill instead of several, and calls answered at whichever site has someone free. You are also pricing several connections and licence counts at once, which is exactly where group buying power tells.
What happens to our old phone lines in London in 2027?
Openreach plans to retire its traditional phone network by 31 January 2027. Ask your provider to review the lines and any connected alarms, payment terminals or lift systems at your London sites. Check number-porting arrangements, installation lead times and power or connection backup before agreeing a migration plan.
The 2027 switch-off affects London too. Openreach plans to retire its traditional phone network by 31 January 2027. Check your phone lines, alarms and payment terminals, and plan the move with your provider.
