Air conditioning in Redbourn

A coaching village on Watling Street

Redbourn High Street runs dead straight because it follows the Roman Watling Street. The council's conservation area statement describes it lined with coaching inns and shops by the 17th century, and in the Georgian years Redbourn was one of the first stops for the London mail coaches to Birmingham, Liverpool and Carlisle. Many of those timber-framed buildings survive behind later brick fronts.

The village grew little in the Victorian years. The big change came after the Second World War, with new housing north and east of the Common. The M1 opened nearby in 1959 and the eastern bypass in 1985, which took the through traffic off the High Street.

Redbourn homes and what they mean for an install

Planning: St Albans City and District Council

Redbourn is in St Albans district, so applications go to St Albans City and District Council. A heating-capable unit on a house is often permitted development if it isn't used only for cooling, is no bigger than 1.5 m³ and passes the MCS 020(a) noise check of 37 dB(A) at neighbours' windows. A semi-detached or terraced house can have one heat pump, a detached house two. Our planning guide covers the rest.

The Redbourn Neighbourhood Plan was made by the council on 12 July 2023, so it now sits alongside the council's own policies when applications in the parish are decided. From 1 April 2028, subject to Parliament, Hertfordshire's councils are due to be replaced by four unitary councils.

The Redbourn conservation area

The conservation area was designated in 1969 and extended in 2001 to take in Scout Farm, the fire station, Crown Street and Water End Lane as far as the ford. The council's statement splits it into three parts: Church End, the Common and the High Street. It counts over 100 listed buildings and structures. St Mary's Church is Grade I, and the Priory and Cumberland House are Grade II*. Cumberland House was built as a hunting lodge for the Duke of Cumberland in 1745.

Inside the conservation area, a unit can't go on a wall or roof facing the road under permitted development, or nearer a bordering road than the house itself. Listed buildings always need consent, whatever the position.

High Street fronts and backs

Most High Street buildings sit right on the back of the pavement, so the front is out. The council's statement also says the rear elevations, especially of the timber-framed buildings, are an important part of the character, because they show from the footpaths and old inn yards behind the street. Several of the high rear garden walls are listed in their own right.

So on the High Street we look for a position that is hidden from those footpaths too: low in a yard, behind a wall, or on a later extension rather than old brick or timber. We take the pipes through the wall behind the indoor unit, with no trunking indoors.

New homes planned in Redbourn

The council adopted its new St Albans Local Plan 2026 on 9 September 2026. It names Redbourn and Wheathampstead as the district's two Large Villages and allocates West Redbourn for 594 homes and land south of Harpenden Lane for 68. The larger Hemel Garden Communities sites are planned as new neighbourhoods of Hemel Hempstead, east and north-east of the town.

If you're moving into a new home, check its planning conditions and the developer's rules before adding an outdoor unit. We size the system to the house, and new, well-insulated rooms often need a smaller unit than you'd expect.

Close to the River Ver

The Ver runs along the south and east of the village, past the old watercress beds and the land the council's statement says was once called the Moor and was much wetter. If your garden is low and near the river, check the government's flood map for your address. We mount the outdoor unit on a raised stand or a wall bracket where standing water is likely, so it stays clear of the ground.

Shops, pubs and businesses

We fit and service systems in shops, pubs, restaurants, salons, clinics and offices on the High Street, and in the units at Redbourn Industrial Park. Wall units suit small shops. Ceiling cassettes suit offices with suspended ceilings. Commercial installs are done in business hours, and on a listed shop we agree the siting and consent first.

Parking on the High Street is tight. Tell us when you book and we'll plan where the van can stop to unload the outdoor unit.
