The government risks making a proposed new development tariff too complicated to work effectively, says a key property industry representative.

Liz Peace, chief executive of the British Property Federation, said discussions between the industry and the government over how to work the proposed Community Infrastructure Levy (CIL) had entered an “interesting phase”. She said: “There’s a danger now we could make it too complex.”

The CIL is based on a scheme developed by Milton Keynes council in which developers pay a fixed charge to the local authority for every home they produce. Peace said: “It worked because they did it quickly and simply. That’s what we need for CIL.”
