Medact is based in London. Our office is five minutes walk from the Old Street roundabout.

Turn right out of ‘Exit One’ from Old Street underground station and walk straight ahead on Old Street for approx. 5 minutes. Turn left onto Pitfield Street (this comes off Old Street) – at this turning there is a Sainbury’s on the corner. Walk up Pitfield Street for approx. 2 mins, and turn left into Charles Square – we’re in the building immediately on the right.
