DWP Raises Benefits for Additional Spouses in Polygamous Households
5/10/2026, 8:16:07 PM
Policy Change Boosts Weekly Support for Additional Spouses
From April, the Department for Work and Pensions (DWP) implemented a 4.8 percent increase in weekly benefits for individuals classified as an “additional spouse” in polygamous households. The increase also applies to wives who have more than one husband under comparable circumstances. The adjustment raises the amount per additional spouse from £119.50 to £125.25 for eligible recipients of Pension Credit or Housing Benefit. The policy applies without a statutory cap on the number of additional spouses that may claim within a single household.
Legal Framework for Polygamous Marriages in the United Kingdom
Bigamy remains illegal under UK law, but the legal status of polygamous unions differs when the marriages were contracted abroad in jurisdictions where polygamy is permitted. In such cases, the marriages are recognized for immigration purposes, allowing individuals to reside in the UK without additional legal barriers. This recognition underpins the eligibility of overseas-married individuals for the DWP benefit increase.
Who Is Affected – Additional Spouses Over State Pension Age
The benefit uplift targets persons who are above the state pension age and are designated as an additional spouse in a polygamous marriage. Eligibility is limited to those receiving either Pension Credit or Housing Benefit. The policy therefore primarily impacts older adults who rely on state-provided financial support and who have multiple spouses recognized under the overseas marriage provision.
Benefit Figures and the 4.8 percent Increase
- Prior weekly entitlement per additional spouse (2025-26): £119.50
- New weekly entitlement per additional spouse: £125.25
- Percentage increase: 4.8 percent
- Applies to each additional spouse in the household, with no upper limit on the number of claimants per residence.
Official Rationale from the Department for Work and Pensions
The Department for Work and Pensions announced that the increase takes effect from April and raises the weekly entitlement per additional spouse. The announcement indicated that the change applies to individuals classified as an additional spouse in polygamous households.
Impact on Benefit Payments
The increase raises the weekly entitlement per additional spouse, which will increase the total amount of Pension Credit or Housing Benefit paid to eligible households. Because there is no cap on the number of claimants, the aggregate payout by the DWP is expected to rise, although the precise fiscal impact has not been quantified in the sources.
Gaps and Unanswered Questions
The sources do not provide data on the number of households that will be affected, nor do they detail any administrative guidance on verifying overseas polygamous marriages. Additionally, the long-term fiscal impact of the uncapped benefit provision has not been disclosed.
