Block Management in Corsham
In Corsham, one radon figure would misrepresent the town in either direction.
Plymouth Block Management runs block, estate and leasehold management for RMCs, right to manage companies and freeholders in Corsham, Pickwick included. Radon across the built-up area spans five classes, from the lowest band to one class 5 square, so the answer depends on the address. With 251 listed entries, consents need checking before external work.
What We Would Put First for a Block in Corsham
Measure Radon by Address, Not by Town
Corsham's built-up area runs from the lowest radon band to class 5, with 18.9 per cent in class 4. For a block on the higher readings we would arrange radon measurement in communal areas, as the published advice recommends, and file the result.
ComplianceConfirm Listed Status Before Specifying
There are 251 listed entries in the built-up area, 222 inside the Corsham conservation area and 37 in Pickwick. Before any external specification we would confirm the listing and conservation area position with Wiltshire Council and obtain the consents needed.
ConsentsShow Insurers the Real Flood Record
Corsham has no flood warning area and no engineered defence, and only one accepted flood outline, from July 1968. We would present that record to insurers at renewal so the block's cover reflects its actual flood history.

What It Costs to Move a Block in Corsham to Us
Management is a fixed annual fee, quoted for the building and agreed before we start. We take no commission and no third-party incentives, so the fee is the whole of what we earn from the building. Taking a block on carries a one-off start-up fee, set by size:
| Block size | Fee |
|---|---|
| Start-up fee, up to 10 units | £420.00 |
| Start-up fee, up to 25 units | £540.00 |
| Start-up fee, 50 units and above | £660.00 |

Just over Half of Corsham Is in the Lowest Band
Wide-ranging, spanning five classes, so a single town figure would misrepresent Corsham in either direction. Just over half the built-up area, 53.0 per cent across six squares, is in the lowest band, where the published advice is that radon measurement is not advised. But 18.9 per cent is class 4, at 5 to 10 per cent of homes at or above the action level. A further 13.3 per cent is class 3, 14.8 per cent is class 2, and one square reaches class 5. So a block on one side of this town sits in ground where the national advice is to do nothing, and a block on the other sits in ground where measurement is clearly advised. The address decides whether measurement belongs on the compliance plan.
That is national advice about the ground, not about the building. The same map excludes basements, cellars and underground spaces at every band, so an enclosed plant room, undercroft or lower-ground flat is still worth a look even here, and whatever is found belongs with the compliance record.
Corsham Without Is Not Part of the Town's Flat Count
The census output areas inside the built-up area hold 4,783 households with 639 in flats, 13.4 per cent. Of these, 517 were in purpose-built blocks, 65 in a converted or shared house, 29 in another converted building and 28 over commercial premises. Corsham Without has 231 purpose-built flats and a name that invites inclusion, but not one of its census output areas falls inside the Corsham built-up area, so its figures do not describe the town. Corsham Pickwick sits wholly inside the town and Corsham Ladbrook 95 per cent inside. Most flats here are in purpose-built blocks, where communal plant and major works planning drive the budget.
No Flood Warning Area Covers Any Part of Corsham
Light. Only one Environment Agency area reaches the town at all, the upper Bristol Avon alert, and it covers 1.77 per cent of the built-up area on the southern fringe. Its published description does not even name Corsham. There is no flood warning area covering any part of the town; the nearest stops 2.8 kilometres away. The recorded history is equally thin. Of five flood outlines intersecting the town, only one has been accepted, from July 1968, and its overlap with the built-up area rounds to zero hectares. For comparison, Melksham has 23 accepted outlines and Chippenham 14. There is no engineered flood defence asset of any kind inside Corsham: all fifteen assets recorded here are natural high ground. Here that reflects the absence of a problem rather than the absence of a response. That record is worth presenting to insurers so a block's cover reflects its actual flood history.
Dense Listed Stock Means Consents Come Before External Work
Two conservation areas touch the town and they are very different in character. The Corsham area covers 268.9 hectares, but only 15 per cent of it lies inside the built-up area, the rest extending over Corsham Court park and the open ground around it. The Pickwick area is small at 15.2 hectares but 85 per cent of it is inside the town. Together they cover 18.9 per cent of the built-up area. Both are recorded as designated by year only, Corsham in 1970 and Pickwick in 1973. Appraisals are recorded for both, though no adoption date is published. For a block inside either area, external works need the designation taken into account in the specification.
251 entries on the National Heritage List fall inside the built-up area, three Grade I, fourteen Grade II* and 234 Grade II, with 222 inside the Corsham conservation area and 37 inside Pickwick. That is about 87 listed entries per square kilometre. A block's listing and conservation area position should be confirmed with Wiltshire Council before any external specification.
A 0.46 Hectare Direction on a Single Site
An Article 4 direction applies, and it is a small and unusual one. It covers 0.46 hectares, a single site, and it removes two classes of permitted development right: the enlargement, improvement or alteration of a dwellinghouse, and the provision of a hard surface. Unlike the direction at Chippenham it does not overlap the conservation area at all, and no listed building falls inside it. Neither an in-force date nor a street schedule is published, so the council has to confirm whether a block's address is affected before works that touch those rights.
The 2015 Core Strategy Still Guides Corsham Decisions
Decided under the Wiltshire Core Strategy, adopted 20 January 2015. The emerging Wiltshire Local Plan reached examination in November 2024 but was withdrawn on 22 May 2026, and its replacement is not expected to be adopted before 30 April 2029. The council states that the 2015 Core Strategy's policies are not automatically out of date, despite its plan period having run to 2026, and will continue to guide development. The Corsham Neighbourhood Plan 2016 to 2026 went to referendum on 14 November 2019. 2,428 electors voted on a turnout of 24.6 per cent, and the result was 2,263 in favour to 162 against. The town council described this as 93 per cent of those voting and the culmination of nearly five years of work. The plan was made in November 2019, though the exact day is not published. Applications for works to a block are decided against the Core Strategy and the neighbourhood plan.

Corsham Questions
Is Radon a Concern for a Block in Corsham?
It depends on where the block stands. Just over half the built-up area, 53.0 per cent, is in the lowest band where measurement is not advised. But 18.9 per cent is class 4, 13.3 per cent class 3, 14.8 per cent class 2 and one square reaches class 5, so a block on one side of town can sit in ground where measurement is clearly advised.
Does the Corsham Article 4 Direction Affect Our Building?
Only if the building sits on one small site. The direction covers 0.46 hectares and removes the rights to enlarge, improve or alter a dwellinghouse and to provide a hard surface. It does not overlap the conservation area and no listed building falls inside it. No in-force date or street schedule is published, so the council has to confirm whether an address is affected.
Which Local Plan Applies to Corsham Now the New Wiltshire Plan Is Withdrawn?
The Wiltshire Core Strategy, adopted 20 January 2015. The emerging Wiltshire Local Plan was withdrawn on 22 May 2026 and its replacement is not expected before 30 April 2029, and the council states the Core Strategy policies are not automatically out of date. The Corsham Neighbourhood Plan 2016 to 2026 was made in November 2019 after a referendum carried by 2,263 votes to 162.
