Cost of living — Mixed picture
minor · low confidence
A deposit return scheme adds a small upfront cost on drinks containers but refunds it when consumers return them, so the net effect on most households is close to zero. The bigger uncertainty is whether banning non-recyclable single-use plastics raises food and drink prices if affordable alternatives aren't available in time.
The evidence
- The policy introduces a deposit return scheme for food and drink bottles and containers, and aims to eliminate non-recyclable single-use plastics within three years, replacing them with affordable alternatives. — libdems.org.uk (manifesto) — “Introducing a deposit return scheme for food and drink bottles and containers. Aiming for the complete elimination of non-recyclable single-use plastics within three years and replacing them with affordable alternatives.”
- The DRS deposit is a small, refundable charge reclaimed on returning the empty container, so it functions as a temporary cost rather than a permanent one for participating consumers. — commonslibrary.parliament.uk (government) — “consumers paying a small, refundable deposit on single-use plastic bottles, glass bottles (in Wales, initially without a deposit), and metal cans, which is then reclaimed upon returning the empty container”
- Eliminating single-use plastics and shifting to alternatives risks raising prices: the policy's goal of 'affordable alternatives' is acknowledged as a key challenge, as some alternatives may carry higher costs. — port.ac.uk (academic) — “The policy's goal of "affordable alternatives" is a key challenge, as some alternatives may carry higher costs or their own environmental footprint.”
- Evidence from Wales suggests a ban on single-use plastics could raise the sales value of affected product groups by around 11%, which could translate into higher retail prices. — resourcefutures.co.uk (media) — “a ban could lead to an 11% (£14 million) increase in sales value across affected product groups”
- A government review found that the overall effects of single-use plastic regulations on the UK internal market have so far been modest. — assets.publishing.service.gov.uk (government) — “the overall effects of single-use plastic regulations on the UK internal market have been modest”
- The IEA raises concerns that DRS costs exceed £1 billion in its first year and that household labour costs for collecting and returning containers are not accounted for in official assessments. — iea.org.uk (media) — “the significant costs of unpaid household labor for collecting, storing, and returning containers are neglected”
Biggest unknown: Whether manufacturers pass the higher cost of plastic-free alternatives through to consumers at the checkout, and by how much.
Our reading: For O2 — whether people can afford essentials — this policy has two main channels. First, the deposit return scheme: because the deposit is refundable on return, it is not a net cost to consumers who participate; it is essentially a zero-cost scheme for diligent returners. However, consumers who do not return containers (notably younger adults, per E10) effectively pay a small tax. The IEA (an advocacy source, noted as such) argues household labour costs are material and uncounted, but without an independent institutional estimate of the magnitude of this pass-through to household budgets, this cannot drive the verdict beyond 'minor'. Second, and more significant for O2, is the ban on non-recyclable single-use plastics. If alternatives cost more — as E30 acknowledges is a real risk and E24's Welsh data suggests (an 11% price rise in affected product groups) — producers may pass these costs through to consumers in food and drink prices. The policy explicitly promises 'affordable alternatives' but provides no committed mechanism or timeline to ensure this, making it aspirational on that specific point. Against this, E26 finds that past single-use plastic regulations had only modest market effects. On balance: the DRS component is near-neutral to slightly negative for non-returners; the plastics ban component carries a credible but uncertain upward price risk, particularly for lower-income households who spend a higher share of income on food and drink. The net direction is mixed — a genuine small upside (refundable deposit, negligible net cost for returners) alongside a genuine small downside risk (higher prices from alternatives). Magnitude is minor; neither channel is large enough to materially shift the inflation basket. Confidence is low because no institutional source (IFS, OBR, ONS) has modelled the consumer-price pass-through directly.
Clean environment & nature — Helps
moderate · moderate confidence
This policy combines a deposit return scheme, a single-use plastics ban, and an end to plastic waste exports — all of which are projected to cut litter, reduce plastic pollution, and lower emissions. The main caveat is that some benefits depend on whether alternatives are genuinely less harmful, and key targets use aspirational rather than binding language.

Biggest unknown: Whether non-recyclable single-use plastic alternatives carry their own environmental footprint, which could displace rather than solve the pollution problem.
Our reading: All three components of this policy point in the same environmental direction — reduced plastic litter, lower emissions, and less pollution exported abroad — and the mechanism is well-evidenced by international comparators. On DRS: the cross-country evidence is strong that deposit return schemes dramatically raise return rates (Germany at 98%), reduce litter (43% of litter by volume is the target containers), and cut methane and carbon emissions. The government's own projected uplift from 70-75% to 85-90% recycling rates is plausible given the international evidence. The IEA (an advocacy source, weighted accordingly) argues benefits are overstated due to intangible valuations and ignored household labour costs — a legitimate methodological critique, but it does not negate the environmental gain, only its monetised magnitude. Absent this policy, DRS is already legislated for October 2027; the marginal additionality here is reinforcing political commitment and embedding it within a wider nature-positive agenda, not creating a new instrument from scratch. On single-use plastics: existing bans on straws, stirrers and cotton buds have already delivered modest gains. The three-year elimination target is ambitious and uses 'aiming for' — aspirational rather than committed — meaning delivery is uncertain. The main risk is displacement to alternatives with their own footprint; academics flag this and the policy's own reliance on 'affordable alternatives' acknowledges the challenge. If alternatives are genuinely less harmful, the environmental gain is real; if not, the benefit is reduced. On export ban: the UK currently exports nearly 600,000 tonnes of plastic annually, much to countries with poor recycling infrastructure. Ending exports would internalise the environmental harm rather than exporting it, with projected infrastructure investment of £800m+. However, this target too uses 'ambition' language, and the EIA notes the government had not yet proposed a full export ban mechanism as of late 2025. Overall, the DRS element is the most robustly evidenced and delivers clear near-term environmental benefit. The plastics elimination and export ban are directionally correct but rely on aspirational language and unresolved delivery mechanisms. The net effect on O6 is a moderate long-term improvement, with near-term gains from DRS implementation and longer-term gains contingent on the wider ambitions being delivered.
