London commuter belt: the true cost of buying in 2026
Buyers priced out of London have long looked to the commuter towns that ring it. But the sale price on the estate agent's board is only the start. Once stamp duty, the deposit, the mortgage, council tax and energy are added up, the "cheaper option down the line" can cost more to own than it first appears — and the town that is cheapest to buy in is not always the cheapest to run.
Below, five of the busiest towns within a typical commute of central London are compared using the same yardsticks: HM Land Registry sale prices for 2025, HMRC stamp duty at each town's typical price, and the 2026-27 council tax set by each authority. Every figure is a real number from a real record — no estimates, no forecasts.
The five towns at a glance
The "typical price" here is the median 2025 sale price for standard residential transactions (detached, semi-detached, terraced and flats) recorded by HM Land Registry in each local authority. The council tax figure is the 2026-27 Band D bill published by each billing authority. The final column is the share of dwellings on the domestic Energy Performance Certificate register rated C or above — a proxy for how cheap the local housing stock is to heat.
| Town | Typical (median) price, 2025 | Sales recorded | Band D 2026-27 | Homes rated EPC C or above |
|---|---|---|---|---|
| Reading | £350,000 | 1,968 | £2,612.77 | 35.5% |
| Brighton & Hove | £415,000 | 3,655 | £2,580.54 | 30.2% |
| Sevenoaks | £490,000 | 1,631 | £2,522.36 | 36.4% |
| Cambridge | £493,500 | 1,265 | £2,467.02 | 49.6% |
| St Albans | £620,000 | 2,091 | £2,419.22 | 39.2% |

Straight away, two patterns stand out. Reading is the cheapest of the five to buy into (£350,000) yet carries the highest council tax bill (£2,612.77). St Albans is the most expensive to buy (£620,000) yet has the lowest Band D of the group (£2,419.22). The price you pay for a home and the annual bill that comes with it are set by entirely different mechanisms, and they do not move together.
Upfront: the deposit and the stamp duty
The two biggest cash sums a buyer needs on day one are the deposit and the stamp duty. Stamp Duty Land Tax (SDLT) in England is charged in slices: nothing on the first £125,000, 2% to £250,000, then 5% up to £925,000 (HMRC, 2026). First-time buyers buying their main residence pay nothing up to £300,000 and a reduced rate to £500,000 — but that relief disappears entirely once the price passes £500,000.
That £500,000 line matters a great deal in this group. It is why the numbers below diverge so sharply at the top end.
| Town | Typical price | Home mover | First-time buyer | Additional property (+5%) |
|---|---|---|---|---|
| Reading | £350,000 | £7,500 | £2,500 | £25,000 |
| Brighton & Hove | £415,000 | £10,750 | £5,750 | £31,500 |
| Sevenoaks | £490,000 | £14,500 | £9,500 | £39,000 |
| Cambridge | £493,500 | £14,675 | £9,675 | £39,350 |
| St Albans | £620,000 | £21,000 | £21,000 | £52,000 |
Source: HMRC SDLT residential rates, calculated at each town's 2025 median. First-time buyer relief applies to a main residence; the additional-property column reflects the 5% surcharge on a second home or buy-to-let.
At Reading's typical price, a first-time buyer pays £2,500 in stamp duty. At Sevenoaks and Cambridge — both sitting just under the £500,000 threshold — a first-time buyer still gets partial relief, but the bill is already close to £10,000. At St Albans, where the typical home costs £620,000, first-time buyer relief has vanished altogether: a first-time buyer pays exactly the same £21,000 as a home mover. The way that relief tapers away between £300,000 and £500,000 is set out in more detail in our guide to how first-time buyer relief tapers between £300,000 and £500,000.
The deposit scales with the price too. A 10% deposit runs from £35,000 in Reading to £62,000 in St Albans; a 25% deposit, from £87,500 to £155,000.
Monthly: the mortgage, the council tax and the energy
For the running cost, the figures below model the mortgage on the typical home at the Bank of England's most recent quoted rate for a five-year fix at 75% loan-to-value — 4.32% (Bank of England, quoted-rate series, April 2026) — over a 25-year repayment term. This is an illustration, not a rate anyone is being offered: an individual's actual rate depends on their lender, deposit and credit profile.
| Town | Deposit (10%) | Mortgage per month (90% LTV) | Mortgage per month (75% LTV) | Council tax per month (Band D) |
|---|---|---|---|---|
| Reading | £35,000 | £1,719 | £1,432 | £218 |
| Brighton & Hove | £41,500 | £2,038 | £1,698 | £215 |
| Sevenoaks | £49,000 | £2,406 | £2,005 | £210 |
| Cambridge | £49,350 | £2,424 | £2,020 | £206 |
| St Albans | £62,000 | £3,045 | £2,537 | £202 |
Illustration at Bank of England quoted rate 4.32% (April 2026), 25-year repayment. Council tax is the 2026-27 Band D bill divided by 12.
The mortgage is comfortably the largest line in every town, and it tracks the purchase price closely — from roughly £1,700 a month at 90% LTV in Reading to over £3,000 in St Albans. Council tax, by contrast, barely moves across the group and even runs slightly lower in the pricier towns.
Why the cheapest town to buy has the priciest council tax
This inversion trips up a lot of buyers, so it is worth explaining. English council tax bands are still pegged to what a property was worth on 1 April 1991 (Local Government Finance Act 1992), and they have never been revalued. The annual Band D bill is then set each year by dividing the council's budget — plus police, fire and other precepts — by the size of its tax base. A town with a large, valuable tax base and tight spending can set a lower Band D than a smaller authority with higher costs, regardless of today's house prices. So Reading's Band D can sit above St Albans's even though a home in St Albans typically costs far more. We cover this disconnect in more depth in how council tax bills compare across England's cheapest and most expensive authorities.
Held flat at today's rates — as a like-for-like comparison, not a forecast — the £193.55-a-year gap between Reading's Band D and St Albans's adds up to roughly £4,839 over a 25-year ownership. It is a modest sum next to the mortgage, but it runs the opposite way to the purchase price.
The energy line
Energy is the running cost that varies most with the age and type of the housing stock. Under the Ofgem price cap, a home rated EPC D or E can cost several hundred pounds a year more to heat than an equivalent home rated B or C. On that measure the five towns diverge: Cambridge has the most efficient stock of the group, with 49.6% of dwellings rated C or above — a reflection of the large volume of newer housing built around the city — while Brighton & Hove, with its dense Regency and Victorian terraces and conversions, has the least, at 30.2%. Sevenoaks and Reading sit in the middle thirties, St Albans a little higher. A buyer weighing two towns on running cost, not just purchase price, would find the warmest homes in Cambridge and the coldest, on average, in Brighton.
The cost that isn't in the sale price: the commute
None of the figures above include the season ticket — and for a household buying in the commuter belt specifically because one or more people travel into London, that is a significant recurring cost, one that can rival the council tax bill over a year. Regulated rail fares are reviewed annually by the Department for Transport, and the price varies widely by route and operator. Rather than quote a single figure that would be out of date within months, it is worth pricing your own journey using the official National Rail season ticket calculator before comparing towns — a shorter, cheaper line into London can offset a higher purchase price elsewhere.
Putting it together
No single town is "cheapest" on every measure. Reading is the lowest entry price and the smallest stamp duty bill, but the highest council tax. St Albans is the priciest to buy and the biggest mortgage, but the lowest council tax and a first-time buyer stamp duty bill no different from a mover's. Cambridge offers the most energy-efficient stock; Brighton the least. The right comparison depends on whether a buyer is weighting the day-one cash cost, the monthly outgoings, or the long-run running bills — and on the commute that brought them to the commuter belt in the first place.
The most reliable way to see what a specific street actually costs is to look it up. Homecost breaks down the mortgage, council tax, energy and stamp duty for any address — try the true cost of a home in St Albans (AL1) or in Reading (RG1) to see the full stack for a real postcode.
