The 2026 regional index
What building work costs across the UK
MVV builds in London. The Estimator, the software that prices building work on this site, is calibrated for the whole of England. This page publishes that calibration at regional and city level: nine English regions and 65 councils and cities, each indexed against the inner west London baseline it prices from.
Research prepared August 2026. Published 13 September 2026.
How to read the index
The baseline
0% is inner west London: the charge levels MVV prices from, not the London average, which itself sits about 9% below.
A live anchor
At that baseline, new high-standard extension space generally runs £2,400 to £2,800 per square metre, before VAT and professional fees.
Charges, not just costs
Where input-cost indices and charge-market evidence diverge, the index follows what firms actually charge, because that is what a client is quoted.
Indicative, ex VAT
The index describes relative price levels. It is not a quote for your project: The Estimator prices those, per postcode area.
Nine regions
England by region
| Region | vs inner London | Range within the region |
|---|---|---|
| London (all-London average) | -9% | -20% to +8% across the borough ladder |
| South East | -21% | -15% (Surrey and the M25 belt) to -28% (coastal Kent and Sussex, Isle of Wight) |
| East of England | -25% | -16% (Hertfordshire fringe: St Albans, Watford) to -30% (Norfolk, Suffolk, coastal Essex) |
| South West | -29% | -24% (Bristol and Bath) to -33% (Plymouth, Torbay) |
| East Midlands | -30% | -28% (Northampton) to -32% (Lincoln) |
| West Midlands | -31% | -29% (Coventry and Warwickshire) to -36% (Stoke-on-Trent) |
| Yorkshire and the Humber | -34% | -29% (Harrogate and York) to -34% (Hull) |
| North West | -32% | -28% (Cheshire and the south Manchester belt) to -37% (Blackpool, east Lancashire) |
| North East | -38% | -37% (Newcastle) to -39% (Durham, Sunderland) |
The mechanics
Why prices vary this much
The instinct is that building prices track materials. Mostly they do not. Bricks, timber and fittings trade at broadly national prices, and on input costs alone most English regions sit only 20 to 30 percent below inner London. The spread a homeowner actually experiences is wider, because the bigger variables are labour, local demand and what established firms can ask: measured on charges rather than costs, the distance between inner London and the cheapest regions grows by roughly another ten points.
Wherever the two tracks diverge, this index follows the charge evidence, moderated toward cost data where charge evidence is thin, because a quotation is a price, not a cost model. That choice is why the East Midlands and the North West sit deeper here than raw cost tables would place them: both regions have input costs close to the national average while their charge markets price with the cheaper half of England.
The baseline matters just as much. Zero on this index is inner west London, which prices roughly 30 percent above the UK mean and about 9 percent above the all-London average. Within London itself the borough ladder spans 20 percent below the baseline to 8 percent above it: a wider spread than any single region outside the capital contains.
65 councils and cities
City by city
South East
Two markets share one region. The M25 and Surrey belt, Guildford and Elmbridge at its head, prices within fifteen to eighteen percent of inner London, close enough that its strongest towns trade at near London levels. The coast behaves differently: Canterbury, Hastings and the Isle of Wight sit 26 to 28 percent below the baseline, and Hastings prices with the cheap coast rather than with its own county's premium towns.
| Council or city | vs inner London |
|---|---|
| Guildford and Elmbridge | -16% |
| Windsor, Maidenhead and Slough | -17% |
| Reading and Wokingham | -18% |
| Oxford | -20% |
| Brighton and Hove | -20% |
| Tunbridge Wells and west Kent | -22% |
| Milton Keynes | -23% |
| Southampton | -24% |
| Medway | -24% |
| Portsmouth | -25% |
| Canterbury, Thanet and Dover | -26% |
| Isle of Wight | -27% |
| Hastings | -28% |
East of England
The steepest internal gradient in England. The Hertfordshire fringe is effectively outer London: St Albans is the strongest above-region market in the country, with trade rates that match or beat the Greater London average, and Watford prices beside it. Cambridge runs hot for its county. The region then falls away fast: Norwich, Ipswich and Peterborough all sit around thirty percent below the baseline, and Peterborough prices with the East Midlands rather than the Cambridge belt.
| Council or city | vs inner London |
|---|---|
| St Albans | -16% |
| Watford and Three Rivers | -17% |
| Cambridge | -20% |
| Chelmsford | -23% |
| Luton | -25% |
| Southend-on-Sea and Basildon | -26% |
| Colchester and Tendring | -28% |
| Norwich | -30% |
| Ipswich | -30% |
| Peterborough | -30% |
South West
Bristol and Bath carry the premium: Bristol ranks among England's most expensive cities to build in, yet still charges around a quarter less than inner London. The far peninsula tells the opposite story. Getting materials into Devon and Cornwall is expensive, but the local charge market does not support London-level pricing, so Plymouth and Torbay sit a third below the baseline, with second-home hotspots such as St Ives and Rock the local exceptions above.
| Council or city | vs inner London |
|---|---|
| Bristol | -24% |
| Bath and North East Somerset | -25% |
| Bournemouth, Christchurch and Poole | -27% |
| Cheltenham and Gloucester | -29% |
| Swindon | -29% |
| Exeter | -30% |
| Cornwall | -30% |
| Plymouth | -33% |
| Torbay | -33% |
East Midlands
The region with the widest gap between what building costs and what builders charge. Input costs here run surprisingly close to the national average, yet every charge signal places the East Midlands with the cheaper half of England: Nottingham, Leicester, Derby and Rutland cluster tightly at thirty percent below the baseline. Northampton keeps a small premium from demand along its logistics corridor.
| Council or city | vs inner London |
|---|---|
| Northampton | -28% |
| Nottingham | -30% |
| Leicester | -30% |
| Derby | -30% |
| Rutland | -30% |
| Lincoln and Lincolnshire | -32% |
West Midlands
Birmingham anchors the region at thirty percent below inner London, with Coventry and Warwickshire holding slightly firmer and the Black Country a step softer. The edges fall further: rural Shropshire and Herefordshire price with the border country, and Stoke-on-Trent is the cheapest sizeable trade market in the evidence base, 36 percent below the baseline.
| Council or city | vs inner London |
|---|---|
| Coventry and Warwickshire | -29% |
| Birmingham | -30% |
| Worcester | -31% |
| Wolverhampton and the Black Country | -32% |
| Shrewsbury and Shropshire | -34% |
| Hereford | -34% |
| Stoke-on-Trent | -36% |
Yorkshire and the Humber
Harrogate and York hold the top of the region: heritage housing stock and affluent catchments support charges above their counties. Leeds and Sheffield price with the big-city cluster in the low thirties below the baseline, while Wakefield, Bradford and Hull stretch toward the regional floor. York is also a reminder that bespoke work carries its own premium wherever you build: one-off projects there price well above the volume housing that sets the averages.
| Council or city | vs inner London |
|---|---|
| Harrogate | -29% |
| York | -30% |
| Leeds | -33% |
| Sheffield | -34% |
| Hull and East Riding | -34% |
| Wakefield | -35% |
| Bradford | -36% |
North West
Manchester anchors at thirty percent below inner London, and the affluent Cheshire belt to its south, Wilmslow to Warrington, holds slightly firmer. Liverpool sits a step below Manchester, and the floor is coastal and eastern Lancashire: Blackburn, Burnley and Blackpool are among England's weakest urban charge markets. Worth knowing: input costs in the North West have been rising faster than London's, so this gap may narrow over the next few years.
| Council or city | vs inner London |
|---|---|
| Warrington and west Cheshire | -29% |
| Manchester, Salford and Trafford | -30% |
| Stockport and Cheshire East | -30% |
| Liverpool and Merseyside | -33% |
| Carlisle and Cumberland | -33% |
| Preston and central Lancashire | -34% |
| Blackburn and Burnley | -36% |
| Blackpool | -37% |
North East
The floor of the model, on every instrument in the evidence base. Newcastle is the region's strongest market and still sits 37 percent below the baseline; Durham and Sunderland, at 39 below, are the cheapest markets in England. It is also a soft market: trade rates here fell through 2024 and 2025 rather than rising, so the distance to London has recently widened from both ends.
| Council or city | vs inner London |
|---|---|
| Newcastle upon Tyne and Gateshead | -37% |
| Middlesbrough and Tees Valley | -38% |
| Darlington | -38% |
| Sunderland | -39% |
| Durham | -39% |
What stands out
- The M25 belt is a near-London plateau. Guildford, Windsor and Slough price within 16 or 17 percent of the inner London baseline, far above their regional averages.
- St Albans charges London money. The strongest above-region market in England: trade day rates on the Hertfordshire fringe match or exceed the Greater London average.
- University and heritage cities run hot. Oxford, Cambridge, Brighton, York and Bath all price above their counties, and Bristol is the South West's premium city.
- The floor is the North East. Durham and Sunderland sit 39% below the baseline, the bottom of the model, with Stoke-on-Trent the cheapest sizeable trade market in the evidence base.
Where the numbers come from
The index was synthesised from eight independent research lanes and 89 source entries: national location factor series, cost consultancy city benchmarks, official statistics, council viability studies, regional trade day rates and consumer charge evidence. Cost indices and charge evidence were weighed separately, and where they diverge the index follows the charge market. The synthesis was then challenged in three independent verification passes, and 28 corrections were applied before the model was adopted. It was prepared in August 2026 and is reviewed as the calibration behind The Estimator updates.
The published index stops at region and city level. The engine itself carries the calibration further, per postcode area, which is how an estimate reflects your street's market rather than a national average.
The index, questioned
Fair questions
- Why is the baseline inner west London rather than a UK average?
- Because the index is calibrated to what a working inner London contractor actually charges, not to an abstract mean. Every figure is relative to inner west London charge levels, and the all-London average itself sits about 9% below that baseline.
- Why is building cheaper in the North than in London?
- Input costs vary less than prices do. Cost indices put most English regions 20% to 30% below inner London, but what established firms actually charge spreads wider than that, and this index follows the charge evidence, because that is the number a client is quoted.
- Is London always the most expensive place to build?
- Inner London is the ceiling, but the commuter belt runs close. Guildford and Elmbridge price around 16% below the baseline, and the strongest fringe towns, St Albans among them, trade at day rates that match or exceed the Greater London average.
- Are these figures quotes?
- No. The index is indicative, exclusive of VAT, and describes relative price levels, not your project. For a priced range specific to your project and postcode, use The Estimator. A quotation only ever follows a site visit.
- Does The Estimator use this index?
- Yes. The same calibration, carried at postcode-area level with local adjustments, is what The Estimator applies when it prices a project, so the number you receive reflects local building costs rather than a national average.
