<span style='color:blue'>The [stereo? computer?] speaker interference could be due to their leads behaving as antennas, and conducting your signal to their respective audio amplifiers; ferrite beads/cores and/or shielded leads may be required.
The TVI could be harmonic [I don't know the frequency of BBC2, or how it relates to your band of operation]; it may be entering the TV set via the antenna/cable lead-in, or even through the power wiring. #A high-pass filter on the TV RF input may work; as well as a "brute-force" AC-mains filter on the power cord. #Note: If your neighbor's installation is CATV, inspect [or have checked] the condition of the cable length(s) and connections. #Here in the States, I've seen such things as drop-lines from poles, rubbed raw from tree limbs [damaging the coaxial shield]; cable in attics/basements chewed by mice/rats; and signal-splitters [for multuple-set installations] having open, unused connections that were not terminated [this is done with a "terminator," an F-connector with a 75-ohm resistor soldered inside].
The doorbell sounds like an electronic type; I've never seen an electro-mechanical one succumb to RFI [yet]. #Ferrite beads on all leads going to the unit may help.
So too, the home-alarm; and there'll be quite a few wires to deal with. #At the alarm console, each wire-run leading to the windows and doors, should get a ferrite bead.
Lights? #Sounds like dimmers are being used. #You didn't say whether these were table-lamps or lights controlled by wall-switches. #Again, ferrite beads may help, but a wall-switch box may be tricky to get into with beads.</span>

<span style='color:blue'>My guess is harmonic or overload [off-air antenna], common-mode [AC mains], or cable leakage [CATV].</span>

<span style='color:blue'>Definitely overload; you're simply slamming the front-end of your poor TV! http://www.qrz.com/iB_html/non-cgi/emoticons/tounge.gif</span>

<span style='color:blue'>RFI/TVI is a contentious beast. http://www.lifeofdebauchery.com/forum/images/smiles/crossbonesgif.gif #It calls for technical ingenuity, a bit of good fortune, and definitely diplomacy when dealing with the neighbors.
Keep us apprised of your findings and progress, Rob. #Good luck! http://www.lifeofdebauchery.com/forum/images/smiles/thumbsup.gif</span>
