Crematoria and burial grounds: use class and consents

Crematorium planning permission is always required, because neither a crematorium nor a burial ground falls within any use class. Both are sui generis, which means there is no permitted development route in, no flexibility borrowed from a neighbouring class, and no route out of the use later without a further permission. A crematorium then carries two additional layers that catch applicants by surprise: statutory separation distances in nineteenth and twentieth century cremation legislation, and an emissions permit from the local authority.

A burial ground has a different second layer, and it is hydrogeological rather than atmospheric.

How crematoria and burial grounds are classified

The Use Classes Order lists the uses that fall within each class and separately identifies uses that belong to none. Crematoria and cemeteries are not named in any class, so they sit outside the system entirely.

Two practical consequences. First, the use of land as a burial ground is a material change of use and needs permission even where no building work is involved, which catches parish councils extending a churchyard onto adjoining land and farmers offering a field for natural burial. Second, because the use is sui generis, the description of development in the permission does the work that a use class would otherwise do, so it should be drafted with care.

Where a crematorium or cemetery sits within the curtilage of a place of worship, the analysis gets more involved, because the chapel may be ancillary to the religious use while the burial land is not. Our note on community cafes attached to places of worship works through the same ancillary question in a different setting.

Separation distances and amenity

The Cremation Act 1902 provides that a crematorium shall not be constructed nearer to any dwelling house than 200 yards, except with the written consent of the owner, lessee and occupier of that dwelling, nor within 50 yards of any public highway, nor in the consecrated part of a burial ground. Those are statutory requirements rather than planning policy, and they cannot be set aside by a planning permission.

Measure them properly at site selection stage. A site that works on every planning criterion and fails the 200 yard test is not a site, unless the consents can be obtained from every affected owner, lessee and occupier, which on a street of houses is impractical.

Beyond the statutory distances, the amenity case is mostly about the things people do not anticipate. Noise from service music and from organ or sound systems. Cortege queuing on the access road. Visitor parking spilling onto a residential street. Views into the committal area from neighbouring windows. None of these is hard to design out, and all of them generate objections if the layout ignores them.

Cremator emissions and the permitting regime

Cremators are regulated as an installation under the environmental permitting regime, with the local authority as regulator for this category. The permit sets emission limits, monitoring and sampling requirements, operating conditions and abatement obligations, including abatement of mercury arising from dental amalgam.

The planning and permitting regimes run in parallel. Planning controls siting, scale, external appearance, access, landscape and the physical height and position of the stack. The permit controls what comes out of the stack and how it is monitored.

That division produces one recurring sequencing problem. Stack height is determined by dispersion modelling, which is a permitting exercise, but the stack appears on the elevations in the planning application. Run the dispersion work before the planning drawings are finalised, or you risk a permission for a stack that the permit will not accept.

Where sensitive receptors are close, an Air Quality Assessment is usually expected with the planning application, and councils normally expect a suitably qualified author with dispersion modelling experience. Professional review of any draft is strongly advised, because the modelling assumptions are what the environmental health officer will test.

Groundwater and burial ground risk assessment

Burial introduces organic and microbiological loading to the ground, and the environmental regulator assesses the risk to groundwater before a site is accepted.

The assessment is hydrogeological. It establishes the geology and the depth to the water table, identifies receptors, and tests the site against the regulator's expectations. The considerations that recur are the distance to potable groundwater abstractions, boreholes, springs and wells, the distance to watercourses and field drains, source protection zone status, and the depth of unsaturated subsoil that will remain beneath the base of a grave.

Figures are commonly quoted for each of these, including a minimum distance of several hundred metres from a potable abstraction, a smaller buffer from watercourses, and at least a metre of unsaturated subsoil below the grave base. Confirm the current figures with the regulator rather than relying on a secondary source, because the guidance is revised and the application of it is site-specific.

Three site types fail routinely. Shallow soils over fissured chalk or limestone, where there is little attenuation. Sites within the inner source protection zone of a public supply. And sites with a seasonally high water table, where the unsaturated zone disappears in winter even though the summer trial pit looked fine. Dig the trial pits at the wet time of year if the programme allows it.

Traffic, parking and cortege arrangements

Crematorium traffic is unusual and standard trip rates describe it badly. Services run on fixed slots, typically with a changeover every thirty to forty-five minutes, so arrivals and departures overlap at predictable moments and the car park has to hold two congregations at once.

Design for that overlap. A one-way circulation route with separate arrival and departure points, a waiting area for the hearse and cortege clear of the through route, a reserved space for the funeral director's vehicles, and parking sized for the largest service rather than the average. Overspill parking on grass with reinforced protection is a common and acceptable answer, provided it is accessible in winter.

Present the case in a Transport Statement built around the service timetable rather than around daily totals. Set out the slot length, the assumed congregation size, the arrival profile and the resulting accumulation. Highway officers respond well to that because it answers their actual question.

Pedestrian provision matters more than at most sites, because mourners include elderly and mobility-impaired visitors. Short, level, well-lit routes from parking to chapel, with seating.

Landscape, screening and memorial areas

Landscape is the substance of these applications, not the dressing. The setting carries the use, the planting provides the screening that makes the amenity case work, and memorial gardens, ash scattering areas and the book of remembrance all need designed space.

A Landscape Strategy should cover the boundary treatment and screen planting with species and sizes at planting, the structure planting that will mature into the setting, the memorial and interment areas with their phasing, surfacing and lighting, water management, and the long-term maintenance regime with a named responsible body. Biodiversity net gain applies, and burial grounds and crematorium grounds can deliver habitat value readily, so the metric position is often favourable where the planting is designed with it in mind.

Phasing deserves attention on burial grounds. A consent for the whole site with a phasing condition is usually better than a series of small applications, because each new application reopens the amenity debate.

Conditions and permit conditions compared

Expect planning conditions covering the approved drawings, materials, stack height and position, landscape implementation and maintenance, hours of operation and of service, external lighting, boundary treatment, surface water drainage, parking and circulation implementation, and a construction management plan. On burial grounds expect a condition requiring compliance with the approved hydrogeological risk assessment and sometimes a groundwater monitoring regime.

The permit conditions sit alongside and cover emission limit values, monitoring frequency and methods, abatement plant operation and maintenance, record keeping and reporting, and operator competence.

Do not duplicate. A planning condition that attempts to set emission limits is usually unnecessary, since the permit covers it, and authorities should avoid conditioning matters controlled by another regime. Where an hours condition is likely, settle its scope at application stage, because varying it later means a fresh application. Our note on changing the hours a use operates sets out that route.

This is general guidance rather than legal advice. Check the position with your local planning authority, the environmental regulator or a qualified professional before relying on it.
