Tesco’s expansion into the doors and windows market could have long-term implications for the UK fenestration sector, according to British Woodworking Federation chief executive Richard Lambert.

The retailer launched its new business selling PVCu products (including look-alike woodgrain windows) last week in tandem with My House Group, with customers offered the incentive of earning double Clubcard points on purchases.

Tesco told TTJ the current ranges are made of PVCu and there are no current plans to offer timber doors at the moment, but “we never say never”, it added.

In his blog on the BWF’s website, Mr Lambert said Tesco’s move was not a surprise as major retailers have been looking to expand into home improvement markets so they can take advantage of the government’s Green Deal, which launches in October, 2012.

“The direction of their thinking is clear; they will want to expand the scope and product range, so I wouldn’t be surprised if they are already thinking about adding timber windows,” he said.

“In the short-term, I think this development is more worrying for the traditional PVCu double-glazing companies, because it’s that market they’re targeting. If Tesco succeeds, then longer term, everyone in the fenestration sector will have to deal with the consequences.”

Tesco is offering casement windows bought and fully installed from £200, while a 700x1300mm vertical sliding sash window has an £838 guide price, earning 1,676 Clubcard points. FENSA accreditation and 10-year product guarantees are included.

Its sales pitch says “No salesmen, no false pricing, no gimmicks, and no pressure”.

Nationwide home improvement specialist Job Worth Doing is partnering Tesco on the project, with Tesco Windows and Doors based at the former’s Norwich site. Weatherseal is believed to be one of the PVC window manufacturers involved.

Tesco already sells loft insulation and solar panels.
