lha bedroom calculator

What this LHA bedroom calculator does

This page helps you estimate how many bedrooms your household may be allowed under Local Housing Allowance (LHA) size criteria. It is especially useful if you are trying to budget for private rent while receiving Housing Benefit or the housing element of Universal Credit.

The calculator gives you two practical outputs:

• Estimated bedroom entitlement (for example, 1-bedroom, 2-bedroom, 3-bedroom rate).
• Estimated weekly shortfall if you enter your weekly rent and local weekly LHA amount.

Quick guide to bedroom entitlement rules

In broad terms, one bedroom is usually allowed for each of the following:

• An adult couple.
• Any other person aged 16 or over.
• Two children under 10, regardless of sex, where sharing is allowed.
• Two children under 16 of the same sex, where sharing is allowed.
• Any child who cannot be paired under the sharing rules.
• A non-resident overnight carer in certain qualifying cases.

For many private-rent cases, the LHA rate is capped at a maximum of 4 bedrooms. That is why this calculator includes an optional 4-bedroom cap toggle.

How the calculator works

1) Adult rooms are counted first

Adult couples are counted as one room each. Any other adult or dependant aged 16+ is generally counted as requiring their own room.

2) Children under 16 are paired where possible

The tool then applies common sharing logic for children under 16, trying to pair children in ways that minimize the number of bedrooms needed while staying within standard LHA rules.

3) Optional finance check

If you provide your weekly LHA rate and weekly rent, the tool estimates the amount covered and any weekly shortfall. This can help with affordability planning.

Example scenarios

Single person

One single adult and no children usually returns a 1-bedroom entitlement (or shared accommodation rate in some age-based cases, depending on policy details not modeled here).

Couple with two young children

One couple plus two children aged 7 and 9 usually returns 2 bedrooms total: one for the couple and one shared room for the children.

Mixed-age children

If children cannot be paired under the sharing rules, the bedroom requirement can increase quickly. This is why entering accurate age/sex breakdowns matters.

If your real award differs

If your local authority or DWP award is different, do not panic. Real claims can include exceptions and evidence-based decisions that a general calculator cannot fully model.

• Check your award letter wording carefully.
• Confirm the Broad Rental Market Area (BRMA) used.
• Ask your council or adviser to explain the bedroom decision.
• Request a reconsideration if you think a rule was applied incorrectly.

Final note

Think of this LHA bedroom calculator as a planning tool, not legal advice. It is best used for quick estimates before you sign a tenancy or set a monthly budget.
