The Uists and Benbecula: an area guide for buyers

The middle of the Outer Hebrides is a chain of islands joined end to end by causeway, so a house on Berneray and a house on Eriskay are on the same road. What differs is how far that road is to a shop, a school and a boat.

In brief

The chain, and what a causeway changes

The Uists are not one island but a run of them, linked by road. The Local Transport Strategy lists the links island by island: Berneray and Baleshare to North Uist, the two Grimsays to Benbecula and South Uist, Flodaigh to Benbecula, Eriskay to South Uist. They were built between 1942 and 2001 to improve accessibility between islands.

A house on Berneray is not on a small island in the practical sense: it is at the north end of a long road. The road is the Spinal Route, of variable quality, with 90km still single track on unsuitable foundations and alignment. The same document warns that the causeways need significant capital maintenance, that in the majority of cases they are a community's single lifeline connection, that the Comhairle cannot fund maintaining them adequately, and that they are at potential risk from sea level rise.

Populations at the 2011 census, from the same table: North Uist 1,254, Benbecula 1,303 and South Uist 1,754, with Berneray 138, Eriskay 143 and the rest below 170.

North Uist and Berneray

Lochmaddy, on the east coast of North Uist, is the ferry port for Skye and a Main Settlement in the Local Development Plan, a category defined as key ports of entry and rural service centres serving wider island needs. The council keeps no office on North Uist, so council business goes to Balivanich or Stornoway. The island is flat and low, machair on the west and lochs and rock on the east. Berneray sits off the north end, joined by causeway, and is where the Sound of Harris ferry lands from Leverburgh.

North Uist is one of the eight Outer Hebrides crofting parishes the Crofting Commission counts separately, and many of the houses advertised sit on croft ground: buying a croft carries the parish counts and the three things the word can mean.

Benbecula, and the airport in the middle

Benbecula is the smallest of the three main islands and carries most of the services. Balivanich, on its west side, is a Main Settlement, and holds the Comhairle's southern isles office, the airport and the Uist and Barra Hospital. Sgoil Lionacleit, the secondary school for the whole of Uist and Benbecula, is a short way south at Liniclate.

The reason Balivanich is bigger than its island would suggest is military. A missile testing range was built in the islands between 1957 and 1958, and is now run by QinetiQ for the Ministry of Defence under a long term partnering agreement, from sites on South Uist, Benbecula and St Kilda: a deep range for weapons trials and an inner range for ground based air defence, in what QinetiQ calls 115,000 square kilometres of sanitised airspace.

Air services matter more here than the island's size suggests. The strategy records five flights a week year round to Glasgow and three to Inverness, and a public service obligation flight to Stornoway funded by the Comhairle.

South Uist and Eriskay

South Uist is the longest of the three, hills on its east side and machair the length of its west coast. Lochboisdale in the south is the ferry port for Mallaig and Oban, and the plan treats Lochboisdale and Daliburgh together as one Main Settlement. Daliburgh has the primary school; the secondary is back up the road at Liniclate. Eriskay is joined by causeway at the southern tip, and the Sound of Barra crossing to Ardmhor runs from there.

A significant proportion of island land and population is under community ownership, on the plan's own account, so the landlord on a croft tenancy here may be a community body rather than a private estate. Ask the agent who it is before offering.

Getting here, and the pressure on the boats

Four ferry routes serve the chain. Uig to Lochmaddy is the short crossing from Skye; Mallaig or Oban to Lochboisdale the long one from the south; Leverburgh to Berneray and Eriskay to Ardmhor the inter island links at either end.

The transport strategy is candid about all of them. It groups Uig to Lochmaddy with Lochmaddy to Tarbert and puts the pair at 40 per cent of car traffic and 35 per cent of passenger volumes to the islands, with significant timetabling and capacity issues and evidence of unmet demand on both. The Sound of Harris has challenges associated with water depth which constrain the service, and the Sound of Barra has capacity pressures. Mallaig to Lochboisdale and Castlebay to Oban run on an ageing fleet, the Oban run being the longest and most weather dependent in the network. Crossing times are in getting here for a viewing.

What comes up for sale

The plan's account holds across the council area: very few volume builders or speculative developers, a land tenure system tied in with crofting, and around 70 per cent of house builds individual developments on windfall sites. Most of what is advertised here is one house built by or for its owner, in a township.

Water, drainage and the checks before an offer

Public water and public sewerage reach the settlements, not the whole chain. The plan requires new development in an area with a public water supply to connect to it, and where there is none the sufficiency and wholesomeness of a private supply has to be demonstrated; every private supply must be registered with the Comhairle, which tests it on the intervals the Lewis and Harris guide sets out. On drainage, a private system should discharge to land, and SEPA requires the discharge to be registered and states that a new one must connect to the public sewer where that is possible.

Low lying roads and causeways in Uist and Barra are identified as at particular risk of flooding, worth asking about for any low lying site.

What is for sale here

What is advertised in the chain is on the North Uist page, the Benbecula page and the South Uist page, and on the district pages for North Uist, Benbecula and South Uist and Eriskay. Crofts are on the crofts page, plots on the land page, long lets on the rentals page and everything on the full list, with the map showing where each sits.
