Chichester Conservation Area Roofing: What You Can and Cannot Do
Roofing work in Chichester conservation areas requires matched clay plain tiles, lime mortar and Code 4–5 lead on visible elevations. Central Chichester, the Cathedral Close, St Pancras and Whyke are designated. Like-for-like repairs are permitted; material changes need consent from Chichester District Council.
Chichester has more listed buildings per head of population than almost any city in England. The Cathedral, the medieval street grid, the Georgian townhouses and the Victorian terraces of St Pancras and Whyke make the city centre one of the most architecturally significant in the South East. For homeowners in these areas, this heritage status brings real constraints on what you can and cannot do to your roof — constraints that apply whether or not your specific property is listed.
Chichester's Conservation Areas
Chichester has several designated conservation areas within the city and surrounding villages. The most significant for roofing work are:
- Cathedral Close and city centre: The most tightly controlled area, covering the Cathedral, the four main streets and the Georgian properties around them. Roofing materials and methods are scrutinised closely here.
- St Pancras: The Victorian terraces east of the city centre. Clay plain tile, lime mortar and like-for-like matching are expected on any work.
- Whyke: Similar Victorian character to St Pancras. Same material expectations apply.
- Village conservation areas: Bosham, Fishbourne, Lavant, Emsworth and many surrounding villages each have their own conservation area designation covering the historic village centre and oldest properties.
Chichester District Council requires conservation area consent for alterations that affect the character of designated areas, including roofing material changes.

What Is and Is Not Permitted Development in a Conservation Area
- Like-for-like repairs using the same materials are generally permitted without consent. Replacing a cracked clay plain tile with a matching one, repointing with lime mortar, replacing a lead flashing — none of these normally require formal application.
- Material changes on a visible elevation — replacing clay tiles with concrete, changing from Welsh slate to a modern equivalent — may require Conservation Area Consent if the change would affect the character of the building.
- Roof alterations — adding roof lights, adding or enlarging dormers, changing roof pitch — require Conservation Area Consent in most cases.
- Work on listed buildings — any alteration requires Listed Building Consent, regardless of scale.
Important: Carrying out unauthorised work on a listed building is a criminal offence, not just a planning matter. If you are unsure whether your work requires consent, ask us — we would rather advise early than deal with enforcement notices after the fact.

Materials Required in Chichester Conservation Areas
Tiles and Slates
Clay plain tiles are the expected material on visible elevations in all Chichester conservation areas. The conservation team at Chichester District Council expects like-for-like replacement on period properties — matching the gauge, texture and colour as closely as possible. Reclaimed tiles are often required for close colour matching on smaller areas. We source reclaimed clay tiles through established suppliers.
Where Welsh slate was the original material — common on some Victorian properties in St Pancras — new Welsh slate or equivalent natural slate is expected. Spanish slate is acceptable in some non-conservation situations at a lower cost.
Mortar
Lime mortar is mandatory for pointing work on historic masonry in Chichester's conservation areas. This covers chimney repointing, ridge bedding on period properties, and any pointing to flint, brick or stone masonry. Portland cement mortar is not acceptable — it causes spalling damage to the surrounding masonry over time and is considered poor practice on historic buildings regardless of planning requirements.
The correct lime mortar specification depends on the masonry type and the building's age. We mix to the appropriate specification for each job — not all lime mortars are the same, and using a mix that is too strong on soft historic brick can cause as much damage as Portland cement.
Lead
Lead is the required material for flashings and valleys on all conservation area and listed building work in Chichester. No modern substitutes are acceptable on buildings within these designations. Code 4 or Code 5 lead is standard depending on the application, and all lead work must be dressed and clipped in accordance with the Lead Sheet Association's current guidance.
Getting Consent Before Work Starts
If your work requires Listed Building Consent or Conservation Area Consent, applications are made to Chichester District Council's planning team. The process typically takes 8 weeks. For routine roofing work on listed buildings, pre-application advice from the conservation officer is often worthwhile — it gives you a steer on what will and will not be approved before formal costs are incurred.
We can advise on whether your specific job is likely to need consent, and support your application with written specifications and photographic documentation where needed. We do not act as planning consultants, but we have enough experience of the local process to give you an informed view at the survey stage. Call 01243 278085 to arrange a free survey.
