Coverage maps use different models and can change. Open every network you are considering and enter SW1A 1AA or the full address.
Coverage is predicted rather than guaranteed. Walls, windows, hills, trees, device frequency support, congestion and maintenance all affect real reception. A short trial with the intended device is the strongest check.
