Property styles in Horsham

Horsham has a strong stock of period cottages and Victorian villas in and around the town centre, alongside 20th-century family housing in the surrounding estates and larger detached homes in the outlying villages. Extension and loft conversion potential varies significantly between the historic core and the more recent suburbs.

Planning considerations

Horsham District Council is the local planning authority. The town centre, including the Causeway, is a conservation area with a number of listed buildings, meaning alterations to visible elevations, windows and materials are more tightly controlled. Some outlying villages also have their own conservation area designations, which we check before advising on likely planning routes.

    Clearing blockages, repairing damaged sections, or relining or replacing pipework as required.

  4. 04

    Testing

    Confirming the drain runs freely and any repair is sound before reinstating ground and surfaces.

    Reinstatement

    Making good any surfaces disturbed to access the drainage run.

Drainage in Horsham: FAQs

Do you provide drainage across all of Horsham?

Yes, we cover the RH12 and RH13 postcode areas in full, including Roffey, Holbrook, Littlehaven, Denne, Trafalgar, Broadbridge Heath, Southwater, Warnham, Colgate.

How do I know if I need a CCTV drain survey?

Recurring blockages, slow-draining fixtures across the property, or unexplained damp near ground level are common signs. A CCTV survey identifies the exact cause and location before any excavation is planned.

Who is responsible for a blocked shared drain?

Shared drains serving more than one property are usually the responsibility of the water company, while private drains serving a single property are the owner's responsibility. We can advise on which applies once the drain run is surveyed.

Is Horsham town centre a conservation area?

Yes, the historic core around the Carfax and Causeway is a conservation area with a number of listed buildings, which affects what changes can be made without planning permission or listed building consent.
