RAF Alconbury housing and COLA at a glance
Alconbury (E), United Kingdom (DoD locality GB001). DTMO files these places under the same locality, so the same rates apply: Wyton, Chicksands, Cottesmore, Leicester, Molesworth, RAF Henlow Military Community.
An E-5 with dependents can rent up to $2,141 a month (1,550 GBP) and receives $1,148 for utilities and maintenance, $3,289 a month in total OHA at the ceiling. With two dependents and 6 years of service, COLA adds about $880 a month. Both are tax-free.
OHA rent ceilings for every grade
OHA reimburses your actual rent up to the ceiling for your grade, so renting below it means a smaller payment, not money kept. Without dependents, the ceiling is 90% of the with-dependents figure.

Estimates use 2026 base pay at the years of service shown and DTMO's spendable-income table (CY2026 tables (effective Feb 1, 2026)). COLA = spendable income × (index − 100) ÷ 100 ÷ 12. Members without dependents living in government quarters receive a reduced rate. Run your exact grade, years of service and dependents in the OCONUS COLA calculator.
How RAF Alconbury compares
The COLA index of 130 is the 8th-highest of 27 United Kingdom localities DTMO prices for OHA, and in the top 38% of the 624 locations worldwide that pay COLA.
Its E-5 rent ceiling ranks 14th of 27 in United Kingdom.
Where the ceiling steps up with rank (with dependents): enlisted $2,072 for E-1 to E-4, $2,141 at E-5 (+$69), $2,498 from E-6 to E-8 (+$357), and $3,039 at E-9 (+$541); officers $2,141 for O-1 to O-2, $2,498 at O-3 (+$357), $3,039 at O-4 (+$541), and $3,384 from O-5 to O-6 (+$345). A promotion that lands before you sign a lease raises what you can rent.
At the ceiling, an E-5 with two dependents draws about $4,169 a month here in OHA and COLA combined, tax-free. The same member receives $2,061 in BAH at the median U.S. housing area. Treat that as a rough guide: OHA pays your actual rent rather than a flat amount, and COLA exists because everyday prices here run higher.
How these rates have moved
The COLA index is 130 (July 1, 2026), the same as on January 1, 2026, though it ranged from 128 to 132 in the months between.

|---|---|---|
| July 1, 2026 | 130 | $880 |

| April 16, 2026 | 128 | $821 |
| January 1, 2026 | 130 | $880 |
