For any that care, from BS 6172 - 2010 Section 12:
"Stability devices Unless otherwise stated in the manufacturer's instructions, a free-standing cooking appliance using a flexible connector shall be fitted with a stability device firmly secured to the fabric of the building."
"COMMENTARY ON CLAUSE 12 Two typical stability devices are shown in Figure 3. In the arrangement illustrated in Figure 3a) the bracket should be adjusted to give the smallest practical clearance between the bracket and the bottom of the engagement slot in the rear of the cooker. For that illustrated in Figure 3b), the stability chain should be kept as short as practicable and fixed firmly to the rear of the cooker.
