Loads.
Foremost just remember that it is a NON-precision approach.

For ATCOs providing an SRA:

Keep it simple. Once the aircraft is on or near FAT one should be able to keep heading changes to a minimum.

In the UK headings on 2nm SRAs are a certainly a readback item.

Having said that keep the RT to a minimum. It is not a PAR requiring continuous talking, repetition or theatricals. Give the crews a chance to coordinate with each other as well as listen to the SRA. Excessive transmissions can be distracting in the cockpit. No need to be fussy with headings. Five degree corrections should suffice and are easy to fly/ select on the heading bug.

Remember that the wind-drift angle will usually gradually reduce during the descent.

Know the CAP413 SRA phraseology. Chap 6 p21.

The suffix 'Degrees' is not necessary during an SRA:

For all transmissions, with the exception of those used for surveillance radar approaches or precision radar approaches, the word 'degrees' shall be appended to heading figures where the heading ends in zero, or in cases where confusion or ambiguity may result.

Get the aircraft stable on, or close to, the Final Approach Track early.
Far better to have a stable approach slightly displaced from FAT at termination range than an unstable approach chasing the FAT. The SRA is effectively a 'cloud-break' requiring realistic energy management at termination range to ensure success.
