Birmingham vs Solihull: the 25-year council tax gap (2026)

Birmingham's 2025 median house price was £239,000 — £91,000 less than Solihull's £330,000, according to HM Land Registry's price paid data. A buyer weighing up the two neighbouring West Midlands boroughs might assume the cheaper city is cheaper on every line of the bill. It isn't quite that simple: Birmingham's council tax Band D charge for 2026-27 is £2,362.90, which is £165.64 a year more than Solihull's £2,197.26 (gov.uk, 2026).

Held flat at today's rates — no assumption that either bill rises or falls — that £165.64 gap adds up to £4,141 over 25 years of ownership, paid by the household living in the cheaper of the two boroughs.

The same-buyer comparison

Running both 2025 medians through the same stack — stamp duty, a mortgage at the Bank of England's quoted 75%-loan-to-value five-year fixed rate, and council tax — shows where the two boroughs actually land once everything is added up.

*Based on the Bank of England's quoted 75%-LTV five-year fixed rate of 4.32% (as of 1 April 2026), a 25-year term, and 75% loan-to-value on each median.

Birmingham is still the cheaper borough overall — £359 a month cheaper, all in — because the £372-a-month gap in mortgage payments swamps the £14-a-month council tax difference running the other way. But the direction of that council tax line is the interesting part: the dearer city to buy in is the cheaper one to pay council tax in.

Why the cheaper city has the higher bill

Council tax bands are fixed to each property's 1991 valuation (Local Government Finance Act 1992), not to what it sells for today. A council's Band D figure is set by dividing its own budget requirement — adult social care, waste collection, local services — by the size of its local tax base, with no mechanical link to current transaction prices. Two boroughs with very different 2025 sale prices can land on almost any council tax relationship, and Birmingham and Solihull happen to sit the "wrong" way round relative to their price gap.

This is not unique to these two boroughs. Other neighbouring-area comparisons on Homecost, including Richmond vs Kingston's £705-a-month gap and the 25-year council tax cost of Wandsworth vs Dorset, show the same pattern: the mortgage payment, not the council tax line, is usually what decides which of two areas is cheaper to live in overall, even when the tax bill itself runs backwards.

A closer look: Harborne vs Solihull town centre

Borough-wide medians blend outer and inner areas. Narrowing to specific postcode districts tells a sharper story. B17 (Harborne, inner Birmingham) had a 2025 median of £340,500 across 292 sales — already well above the Birmingham-wide figure — while B91 (Solihull town centre and Shirley) sat at £458,000 across 485 sales. The borough-level price gap holds, and widens, at this more local level too.

The two boroughs also differ in what kind of home is typically sold. Birmingham's 2025 sales were 34.2% terraced and 36.2% semi-detached, with detached houses making up just 11.1%. Solihull's mix leans the other way: 25.6% detached and 36.4% semi-detached, with terraces at only 19.0% of sales. Energy performance tracks the same divide — 38.4% of Solihull's certified homes are rated EPC C or above, against 26.2% in Birmingham, consistent with Solihull's newer and larger housing stock (EPC Open Data Communities, certificates current to February 2026).

Stamp duty at each median

Birmingham's £239,000 median sits entirely inside the first-time buyer nil-rate band, so a first-time buyer pays nothing in Stamp Duty Land Tax; a home-mover pays £2,280. Solihull's £330,000 median crosses the £300,000 line, so a first-time buyer pays £1,500 and a home-mover pays £6,500 (HMRC Stamp Duty Land Tax rates, 2026). That gap — on top of the larger deposit a £330,000 purchase requires — is a real up-front difference, separate from the ongoing monthly costs above.

What this means for a comparison, not a recommendation

None of this points to one borough being the "better" choice — that depends on a buyer's own budget, commute and preferences, and on a property's individual condition, which this data cannot capture. What it does show is that comparing two neighbouring areas on purchase price alone can miss a genuine, measurable difference running the other way on a bill that's paid every year for as long as the home is owned.
