If high speed, high quality connectivity is important to your business, then buy a leased line.
Expect to pay in the ballpark of £300 per month for 1G/1G symmetrical on a 3 year contract, although it depends on exactly where you are and which providers are available where you are. There may also be Excess Construction Costs if you are not close to any existing leased line network.
Leased lines are usually installed within a 3-4 month timescale - much faster if the network already has a presence in your building.
If you are a small business that can't afford £10 per day, then you can look into 4G/5G wireless options; and if those aren't available then there's always Starlink, which costs around £100 per month once you've taken the power requirements of the terminal into consideration.
