Reports needed for a crematorium application

Before any of the usual reports for a crematorium planning application matter, check the site against the Cremation Act 1902. Section 5 prohibits construction of a crematorium within 200 yards of a dwelling house, unless the owner, lessee and occupier all consent in writing, and within 50 yards of a public highway. Those distances are statutory, they are measured in yards rather than metres, and they have sunk more crematorium schemes than any planning policy.

The statutory siting constraints under the Cremation Act 1902

Take the 200 yard standoff first. It applies to a dwelling house, so an unoccupied agricultural building or a commercial unit does not trigger it, and consent from all three interests in a dwelling can release it. Getting that consent from a neighbour who also objects to the application is, predictably, rare.

The 50 yard standoff from a public highway is absolute in a way the first is not. It constrains the position of the crematorium building itself rather than the access, car park or grounds, which gives designers room to work with on a large site and almost none on a small one.

Measure both from the building line of the proposed crematorium, show the measurement on a drawing, and state the position in the planning statement. Officers will check it, and so will objectors. The Act also prevents construction in the consecrated part of a burial ground.

The Act sits alongside, not instead of, planning policy. Clearing the 1902 Act tells you the scheme is capable of being built, not that it will be permitted.

Emissions, abatement and the environmental permit

A crematorium is a permitted installation regulated by the local authority under the Environmental Permitting (England and Wales) Regulations 2016. The permit covers combustion conditions, emission limits, monitoring and, most importantly for the design, abatement of mercury released from dental amalgam.

Abatement plant is large. It needs a building volume, a maintenance access and, in most designs, a flue of a height determined through the permit and any chimney height approval. Designers who treat the chapel as the whole building and add the plant later end up with a lean-to that dominates the entrance elevation.

Planning and permitting are separate consents with separate applications, and a planning authority should not duplicate the pollution control regime. It will still want an Air Quality Assessment covering dispersion from the flue to nearby receptors, the effect on any Air Quality Management Area, and construction dust. Where a school or hospital is within the study area, expect close scrutiny.

Apply for the permit in parallel with the planning application. Discovering at permit stage that the flue has to be three metres taller than the approved drawings means a section 73 application and more delay.

Traffic, arrival and departure profiles and parking

Crematorium traffic does not behave like anything else. Services are booked in fixed slots, often at 45 minute intervals, and each one generates a burst of arrivals in the 20 minutes beforehand and a burst of departures afterwards. Two services overlap in the car park.

That makes the peak demand far higher than an average trip rate suggests. A Transport Assessment should model the booked service pattern rather than a generic weekday peak, and the parking provision has to serve two congregations at once plus staff, funeral directors' vehicles and the cortege itself.

Design in a holding area for cortege vehicles off the public highway, a separate route for hearses to the committal entrance, and a one-way circulation that prevents a departing cortege meeting an arriving one. Highway authorities focus on the junction, and rightly, because vehicles arriving in a slow procession behave differently from ordinary traffic at a give-way.

Set out the booking pattern you are applying for. If the operational model later changes to 30 minute slots, the traffic assessment no longer describes the development.

Landscape setting and the memorial garden

The grounds do most of the work in making a crematorium acceptable. A Landscape Strategy should cover the arrival sequence, the garden of remembrance, the scattering areas, memorial planting and the treatment of the boundary with neighbouring land.

On a countryside or Green Belt site the landscape and visual case carries the application. Buildings should sit low, use quiet materials and avoid a suburban car park frontage. Existing hedgerows and trees are assets, and removing them to gain parking is usually the wrong trade. The evidence approach overlaps with what is needed for a replacement dwelling in the Green Belt, where openness and siting are argued in much the same way.

Memorial gardens grow over time. Show the long-term plan for memorial provision, because a scheme approved with a modest garden that later fills with plaques, benches and planting has changed in character without anyone applying for anything.

Noise, hours and the residential interface

Three noise sources need addressing: building services and abatement plant, vehicle movements including car doors and engines in the car park, and amplified music or a public address system inside the chapel.

Plant noise is assessed against the local background using the standard industrial and commercial methodology, with a rating level at the nearest dwelling and corrections for tonal character. Car park noise is a cumulative assessment rather than a single source, and is best mitigated with layout, bunding and planting.

Hours of operation are usually conditioned. Ask for the hours the business actually needs, including early starts for staff and evening services in winter, rather than accepting a standard set that will need varying in two years.

Drainage and the burial of cremated remains

Cremated remains are inert, and the interment or scattering of ashes does not raise the groundwater questions that burial does. Do not let an objector's assertion to the contrary go unanswered in the statement.

The real drainage issue is the car park. A crematorium has a large area of hardstanding relative to its floorspace, which means surface water attenuation, a treatment train appropriate to a trafficked area, and oil interception. On a greenfield site the discharge rate will be held to greenfield run-off rates, and the attenuation has to go somewhere that does not conflict with the memorial grounds.

Where a scheme includes a separate burial ground or natural burial area, the Environment Agency's position on burial and groundwater applies and is a different conversation entirely.

Ecology and the grounds management plan

Biodiversity net gain applies, and crematoria are unusually well placed to deliver it on site. Large grounds, low building coverage and a maintenance regime already geared to horticulture make a strong gain plan achievable without buying units.

Commission a Preliminary Ecological Appraisal early enough to catch survey seasons, particularly for bats in any existing building on the site and for reptiles on rough grassland. The statutory metric has to be completed by a competent person under the Environment Act 2021, and the gain plan is approved by the authority after permission.

Tie the ecology and the landscape work together in a single grounds management plan covering 30 years. That document answers the biodiversity condition, the landscape condition and the question of what the memorial gardens will look like in a generation.

The evidence pack for a countryside site

For a crematorium on a countryside site with no existing buildings, an English authority will usually expect a Planning Statement addressing need and the countryside policy position, a Design and Access Statement, a Transport Assessment with a parking strategy and a Travel Plan, an Air Quality Assessment, a Noise Impact Assessment, a Landscape and Visual Impact Assessment with a Landscape Strategy, a Preliminary Ecological Appraisal with the statutory metric, an Arboricultural Impact Assessment where trees are affected, an Archaeological Desk-Based Assessment, a Flood Risk Assessment and Drainage Strategy, a Lighting Assessment, and a Construction Management Plan.

Need is the argument that decides these applications in the countryside. Set out the catchment, the travel times to existing facilities and the capacity position, using published data rather than assertion, and be straightforward about the fact that a commercial operator benefits from the permission.
