Planning Permission in Oldham
Metropolitan District in North West · Last updated April 2026
Oldham is a metropolitan borough in Greater Manchester, comprising the town of Oldham and surrounding communities including Chadderton, Royton, Shaw, Crompton, Failsworth, Lees, and the Saddleworth villages. The borough sits on the western slopes of the Pennines, giving it a distinctive topography from lowland urban areas to upland moorland. Oldham has a rich textile heritage — the borough once had more cotton spindles than any town in the world and retains 103 surviving mill buildings. It has 33 conservation areas, 531 listed buildings (including 13 Grade II* but notably no Grade I listed buildings — the only Greater Manchester borough without one), and significant Green Belt land.
Oldham's development plan comprises the Joint Core Strategy and Development Management Policies DPD (adopted November 2011) and Places for Everyone (adopted March 2024), the joint strategic plan for nine Greater Manchester districts. A new Oldham Local Plan is being prepared. The borough introduced a borough-wide HMO Article 4 direction effective from January 2026. Oldham does not levy CIL, relying on Section 106 agreements. Places for Everyone allocates strategic sites including Beal Valley, Broadbent Moss, and Stakehill.
Oldham is undergoing significant regeneration. The Spindles town centre redevelopment (c.£65M) is transforming the former Spindles Shopping Centre into a mixed-use destination. Foxdenton (a Places for Everyone allocation) will deliver around 500 homes. The borough's Housing Delivery Test score of 91% triggers an action plan requirement but avoids the presumption. Oldham's planning approval rate is 88%, with 96.2% of major and 95% of householder applications decided on time. The Saddleworth villages and moorland in the eastern part of the borough present a dramatically different planning context to the urban west.

Permitted development in Oldham
Permitted development rights in Oldham follow the national GPDO but are restricted in several ways. From January 2026, a borough-wide Article 4 direction removes PD rights for converting dwellings (C3) to small HMOs (C4), requiring planning permission for all small HMO conversions. PD rights are restricted in all 33 conservation areas, and the borough's extensive Green Belt (covering much of eastern Oldham and Saddleworth) imposes additional constraints on extensions — extensions must not result in disproportionate additions over the original building. The district's 531 listed buildings (13 Grade II*, 518 Grade II) always require listed building consent. Oldham's 103 surviving mill buildings present particular challenges for conversion schemes — many are locally listed or in conservation areas.
What Oldham expects from your project
Oldham's built environment reflects its textile heritage and Pennine topography. The borough's distinctive character comes from its 103 surviving mill buildings — more than any other Greater Manchester district — many built in local Pennine gritstone. Traditional construction in the eastern and northern parts uses stone, while the western areas are predominantly brick. The Saddleworth villages have a distinctly rural Pennine character, with stone-built cottages and weavers' houses quite different from urban Oldham. Major regeneration is transforming the town centre: the Spindles (c.£65M) is converting the former shopping centre into a mixed-use destination with residential, commercial, and community uses. The Mumps area is being regenerated around the new Metrolink stop (opened 2012). Design expectations in Saddleworth are particularly high, with the Saddleworth Parish Design Guide supplementing borough-wide policies.
Local Plan: Oldham Local Plan 2011–2026
Oldham adopted its Local Plan in November 2011. The plan focuses regeneration on Oldham town centre and sets out policies for housing, employment and the natural environment. Oldham forms part of the Greater Manchester conurbation and its local plan sits within the strategic context of Places for Everyone (adopted 2024).
Emerging / replacement plan
Oldham is preparing a new Local Plan following the adoption of Places for Everyone. A Regulation 18 consultation on a new Local Plan is anticipated in 2025–2026.
33 conservation areas
Oldham has a high number of conservation areas. Check whether your property falls within one before starting any work — conservation area status significantly restricts what you can do without planning permission.
Conservation areas in Oldham
33 designated conservation areas
Oldham has 33 conservation areas covering the borough's diverse heritage, from Victorian commercial centres to Pennine villages. Oldham Town Centre conservation area protects the civic core including the landmark Oldham Town Hall (Grade II*, 1841) and the Old Town Hall (1841, now Oldham Coliseum Theatre site). The Saddleworth villages — Uppermill, Delph, Dobcross, Diggle, Greenfield, and Lydgate — each have conservation areas protecting their distinctive Pennine stone character. Failsworth Pole conservation area covers the historic south of the borough. Notable Grade II* buildings include Alexandra Mill, Chadderton (one of Oldham's finest surviving cotton mills), the Lyceum (Union Street), and Bank Top Mill. The Huddersfield Narrow Canal (through Saddleworth) and the Rochdale Canal (through Shaw) add heritage character.

Listed buildings in Oldham
There are 531 listed buildings in Oldham. If your property is listed, permitted development rights are significantly restricted.

Always check with Oldham's conservation team before starting any work on a listed property.
Planning application statistics
Year ending September 2025 | Source: MHCLG planning application statistics
Oldham received 899 planning applications and decided 853 in the year ending September 2025. The approval rate of 88% is above the national average of 86.9%. Major applications are expected to be decided within 13 weeks, while householder and other non-major applications have an 8-week target. The “in time” figures include decisions made within agreed extensions of time.
Oldham's Housing Delivery Test score of 91% (2023 measurement) is between 75% and 95%, which triggers an action plan requirement but avoids the tilted balance/presumption. 1,406 homes were delivered against a requirement of 1,542. The borough's approval rate is 88%, with 96.2% of major applications and 95% of householder applications decided on time — both above national averages. Oldham does not levy CIL, relying on Section 106 agreements for developer contributions. The Saddleworth Neighbourhood Area was designated in 2018 and a neighbourhood plan is in preparation, which would be the borough's first.
If your project complies with permitted development rules, you don't need to worry about approval rates — a Lawful Development Certificate is a factual assessment, not a judgment call.

Housing delivery in Oldham
Housing Delivery Test 2023 measurement | Source: MHCLG
Oldham delivered 1,406 homes against a requirement of 1,542 over the three-year measurement period, giving a Housing Delivery Test score of 91%. This is below the 95% threshold, which means Oldham must publish an action plan setting out how it intends to increase housing delivery. For homeowners, this is a positive signal — the council is under pressure to approve more housing, which can make planning officers more receptive to well-designed residential applications and extensions that add living space.
Lawful Development Certificates in Oldham
A Lawful Development Certificate (LDC) is formal confirmation from Oldham that your project is lawful under permitted development rules. It is not legally required before you build, but it is the only official document that proves your project did not need planning permission. Most solicitors will ask for one when you come to sell, remortgage, or insure your property.
Oldham decided 500 householder applications in the year ending september 2025. Their 8-week performance of 95% is above the national average of 93%, which suggests LDC applications are likely to be processed on time. LDC applications follow the same 8-week statutory determination period as householder planning applications.
How to apply for an LDC in Oldham
You can apply for a Lawful Development Certificate through the Planning Portal or directly through Oldham's website. You will need to submit:
- A completed application form (available on the Planning Portal)
- A site location plan at 1:1250 or 1:2500 scale
- Existing and proposed floor plans and elevations
- A written description of the proposed works and how they comply with the GPDO 2015
- The application fee of £258
Oldham must issue a decision within 8 weeks. If the application is approved, the certificate is a permanent legal record that the development is lawful. If refused, you can appeal to the Planning Inspectorate or amend your project and reapply.
