Bournemouth, Poole and Christchurch have shared one council since 2019, and with it one council tax bill: Band D costs £2,435.58 a year everywhere in the Bournemouth, Christchurch and Poole (BCP) area for 2026-27, whichever of the three towns a property sits in (gov.uk council tax data). What buyers actually paid for a home in 2025 is a different story. Land Registry data shows a median sale price of £306,000 in Bournemouth, £335,000 in Poole and £415,000 in Christchurch — a £109,000 gap inside a single billing authority, driven entirely by what's on the market in each town, not by anything the council charges.
The three towns, one council tax bill
Homecost's analysis of 5,516 category-A residential sales completed in 2025 (HM Land Registry Price Paid Data) splits cleanly by town within the BCP unitary authority:
| Town | 2025 median | Mean | Sales (n) |
|---|---|---|---|
| Bournemouth | £306,000 | £350,008 | 2,687 |
| Poole | £335,000 | £418,615 | 1,962 |
| Christchurch | £415,000 | £449,009 | 867 |
All three towns show a mean well above the median — a coastal-prime tail of higher-value sales pulling the average up, most pronounced in Poole and Christchurch. Every household in all three pays the same £2,435.58 Band D rate, itself slightly above the England-wide average of £2,410.97 across 296 billing authorities.
What it actually costs each month
Using a consistent basis — 25% deposit, a 25-year repayment mortgage at the Bank of England's quoted 75%-LTV five-year fixed rate of 4.32% (as of April 2026), plus council tax — the monthly gap tracks the purchase price almost exactly, because the council tax line is identical for all three:
| Town | Price | 75% LTV loan | Mortgage (P&I) | Council tax | Total/month |
|---|---|---|---|---|---|
| Bournemouth | £306,000 | £229,500 | £1,252 | £203 | £1,455 |
| Poole | £335,000 | £251,250 | £1,371 | £203 | £1,574 |
| Christchurch | £415,000 | £311,250 | £1,698 | £203 | £1,901 |
The gap between Bournemouth and Christchurch works out to roughly £446 a month at these medians — almost entirely the mortgage line, since the council tax figure doesn't move. These are illustrative figures based on the quoted rate and standard terms; an individual mortgage offer depends on the lender, deposit, term and the buyer's own credit profile.

Stamp duty at each price point
Stamp Duty Land Tax (SDLT) is calculated on the purchase price, not the council area, so it scales with the same price gap:
| Town | Median price | Mover SDLT | First-time buyer SDLT |
|---|---|---|---|
| Bournemouth | £306,000 | £5,300 | £300 |
| Poole | £335,000 | £6,750 | £1,750 |
| Christchurch | £415,000 | £10,750 | £5,750 |
Bournemouth's median sits only just above the £300,000 first-time buyer nil-rate ceiling, so a first-time buyer there pays SDLT on a thin £6,000 slice. In Christchurch, where the median clears £400,000, first-time buyer relief still applies but on a much larger taxable slice above £300,000. None of the three medians reach the £500,000 point at which first-time buyer relief withdraws completely. These figures come directly from HMRC's published SDLT bands; a conveyancer confirms the exact figure, and eligibility, on completion.
Why Bournemouth is cheapest: it's flat-heavy
The price gap isn't random — it tracks what kind of home is actually selling in each town. Bournemouth's 2025 sales were 43% flats (1,162 of 2,687), the largest single segment and easily the highest flat share of the three. Christchurch, by contrast, is dominated by detached houses (377 of 867 sales, 43%) and has the smallest flat share (23%):
| Town | Detached median | Semi median | Terraced median | Flat median | Flat share of sales |
|---|---|---|---|---|---|
| Bournemouth | £465,000 | £335,000 | £286,000 | £207,000 | 43% |
| Poole | £427,500 | £330,000 | £292,250 | £225,000 | 28% |
| Christchurch | £541,000 | £383,750 | £335,500 | £225,000 | 23% |
Detached houses in Christchurch actually cost more than detached houses in Bournemouth or Poole too — so the town-level gap isn't purely a mix effect. But the heavier flat share pulls Bournemouth's overall median down further than the underlying house prices alone would suggest.
The twist: the priciest town has the newest housing stock
The obvious assumption is that Bournemouth, the cheapest town to buy in, should also be the cheapest to make energy-efficient, since older housing usually needs more retrofit work. The EPC register says the opposite. Looking at the latest Energy Performance Certificate for every address in each town (62,490 certificates across the three towns), Christchurch has the highest share rated C or above at 38.8%, ahead of Poole (37.2%) and well ahead of Bournemouth (28.7%).
The explanation is build era, not price. Bournemouth's certified stock is 57% pre-1945, by far the oldest of the three towns; Christchurch's is only 21% pre-1945, with more than half its stock dating from the 1945–1982 building boom. Nationally, EPC C-or-above rates track build era almost monotonically — homes built after 2003 are roughly five times more likely to rate C or above than pre-1945 stock, reflecting successive tightenings of Building Regulations on insulation and glazing. Christchurch's newer average building stock explains its EPC lead more directly than its higher price does.
EPC ratings estimate a home's built-in energy efficiency rather than its current market running cost, so these figures are best read as a directional comparison between the three towns, not a pound-for-pound bill difference.
Reading the gap
None of this means one town is a better place to buy than another — that depends on a buyer's own budget, needs and circumstances. What the Land Registry, EPC and council tax data show is that within a single council area, price differences of this size can exist for reasons that have nothing to do with local services or tax rates: housing type mix and building age explain far more of the Bournemouth-Poole-Christchurch gap than anything the council controls. Anyone comparing the three towns can check a specific street's numbers via the BCP postcode tool, see how the wider conurbation compares to nearby coastal cities in Portsmouth, Southampton and Bournemouth: Solent coast buy vs run, or read the borough-wide numbers in Average house price in Bournemouth, Christchurch and Poole.
