minimax/minimax-m3.1-flash:free: What Hollinbrook residents think of three-weekly bin collections

The decision: whether to move general waste collection to every three weeks across the whole district, to do so with extra support for households that need it (a larger bin, or extra collections of nappies and hygiene waste), to pilot it in some areas first, or to drop the proposal.

    Continues if Yes

  3. S3

    What is the postcode of the home where you currently receive Hollinbrook District Council's waste collection? If you do not know your postcode, please use the 'Find your postcode' link provided with this survey. Your postcode will be used to check eligibility and identify your ward, and will not be shown with your published survey answers.

  4. Q1

    The council has not yet made a decision. It is considering changing general-waste (black-bin) collections from once every two weeks to once every three weeks across the whole district. Food-waste collections would remain weekly, and recycling collections would remain every two weeks. The council needs to find £3.1 million in savings next year and estimates that this change would save about £600,000 a year. The council says the change may encourage more recycling, but it does not yet know what the effect would be in Hollinbrook; some households may also find the longer interval harder to manage. Overall, do you support or oppose this proposal?

    • Strongly oppose
    • Oppose
    • Neither support nor oppose
    • Support

    • Move to once-every-three-week collections across the whole district, with extra support for households that need it

Sample plan

Use identical questionnaire wording in both modes; record consultation source through the link rather than asking respondents a mode question. Open consultation: provide one public link on the council website and promote it through social media and the residents' magazine; screen for eligible resident adults but do not impose quotas because responses are self-selected. Report open results separately and do not treat them as a probability sample or combine them with panel results for headline population estimates. Residents' panel: draw a systematic random sample of occupied residential addresses stratified across all six wards, select one adult per sampled address, and send a letter with a unique one-use link and reminders. Use 420 completed panel surveys as the initial wave, approximately 70 per ward. This cannot meet the stated ward-level precision: with 70 completes per ward, the worst-case 95% margin of error is about plus or minus 11.7 percentage points. Meeting plus or minus 6 points at 95% confidence requires at least 267 completed panel surveys per ward, or 1,602 in total, under simple random sampling; plan for approximately 300 per ward, or 1,800, to absorb nonresponse and weighting effects, and continue recruitment until each weighted ward estimate has an actual 95% confidence-interval half-width no greater than 0.06. If 420 is a hard cap, the precision requirement is mathematically infeasible and must either be relaxed or replaced with the actual confidence intervals. Set recruitment quotas and post-stratification or raking weights using council or ONS benchmarks for age and tenure within each ward, classify postcodes using ONS rural-urban classifications, monitor differential response, and deduplicate panel returns. Randomize the four substantive options in Q4 and the factor order in Q9 while keeping the response scales in Q1, Q2 and Q8 fixed.
