Very unusual for the external filling loop not to be in place, regulations used to say they had to be removed but I've never come across an installation where the plumber hasn't left it in situ.
Virtually all systems need to be re-pressurised occasionally, its ridiculous to expect the owner to have to call out a plumber each time.
Admittedly many people over-pressurise the system and destroy the expansion vessel and/or boiler tank so I've heard some landlords have the filling loop removed.
Don't forget to tell the plumber he will need a Worcester filling key with him (assuming you haven't got the connections for a filling loop), it could save him pratting around looking for one when he arrives at yours.
If you have got the external filling loop connections, the loop is less than £10 at places like toolstation.

If the system was working and there were gurglings from the radiators it sounds like you have introduced air into the system somehow. Possibly by replacing the radiator and not filling it with water.
The fact that it is isn't working now is probably because you have introduced a slow leak, or you have removed so much water that the pressure - after it cooled down - is zero.
You can buy a refilling hose today from screwfix or wickes of B&Q or probably homebase. They are all open. Somewhere near your boiler there will be a valve on the cold water supply with an outlet for the hose. The other end should go to a one-way fitting into your central heating pipe, somewhere nearby. You connect the two, turn on the valve and observe the pressure. You need to set it at one or two bars.
Then you check for leaks, and after rectifying them, you bleed any air from the radiators, and repeat the filling process as needed until you have no air in the system and one or two bars pressure. You can then relight the pilot light and it should work.

Woo Hoo!!  I now have heat. Managed to dig out some PTFE tape from my box of gubbins and swathed the valve with it and replaced the water in the boiler and I now have heat without a leaking radiator valve! Thank you very much for all your advice.
