Privatisation was conceived as a means of making services more efficient and also of getting politicians off the backs of the nationalised industries. Nearly a decade after the first privatisation, British Telecom, the politicians are out of the way. Instead, we have the regulators, who appear to picking up where the politicians left off.
The regulators, according to critics, have turned into the enemies of privatisation. Ofgas, Offer, Oftel and company are accused by right-wing think tanks such as the Adam Smith Institute of high-handedness and arm- twisting. The privatised utilities say much the same: John Baker, chief executive of National Power, one of the subjects of the current flotation, argues that regulators have been consumed by the "cult of personality" and wants to see them replaced by five-person tribunals. Clearly, there is an element of special pleading in this. Equally clearly, the system is not working as its theorists intended.
The Conservatives' privatisation programme had to contend with notoriously monopolistic terrain. Some free-market Tories thought there should be no price limits at all when British Telecom was privatised. Most people, however, favoured, "light touch" controls - hence the creation of Oftel and the "RPI-X" formula, supposed to safeguard consumers from monopoly pricing while letting BT run its business as it chose.
RPI-X allowed privatised companies price increases based on the inflation rate plus or minus a figure arrived at by the regulator after negotiation. When linked to five-yearly pricing regimes, it gave them a simple target and a stable financial environment - safe from the politically inspired wage setlements and enforced buy-British deals which marred the running of the nationalised industries. By concentrating on pricing, the system was set up to encourage efficiency. It avoided, for example, the "cost- plus" syndrome seen in the US where controls are based on an assessment of the company's costs - which it thus has less incentive to reduce.
Even so, according to George Yarrow, director of the Regulatory Policy Institute at Hertford College, Oxford, there was a "widely held view that price regulation was temporary, to hold the fort until competition arrived." In 1987, Sir Alan Walters, then Margaret Thatcher's economic adviser, said the proportion of privatised utilities' output covered by price caps was "confidently expected to decline in the future".
In fact, the reverse has occurred. Controls were extended across the full range of British Telecom's business and, with each successive privatisation, regulation became ever more detailed. Water, for example, involved several companies and enabled the regulator to compare costs between them. It also involved quality and environmental standards imposed by government - the multi-billion-pound programme to clean up rivers and beaches. Regulation was thus extended from prices to standards of service and investment programmes.
The phenomenon of "regulatory creep" - the tendency of regulation to become more intrusive - is not difficult to explain. First, the powers of the regulators are ill-defined - much therefore depends on personal attitudes. Second, they are more or less a law unto themselves: companies can only appeal to the Monopolies and Mergers Commission. And third, they are operating in an arena which, thanks to price rises, profit bonanzas, executive perks and cuts in services, has become highly politicised. It is thus in the regulator's interest to cover his or her own back - to make sure that the utilities are not pulling a fast one.
Regulation has also come under fire for its inscrutability. Discussions take place behind closed doors - the companies prefer this for commercial reasons - but even if they were out in the open, it is doubtful if many people would understand them.
The row over electricity is a case in point. It has long been acknowledged among industry-watchers that electricity privatisation was too generous to shareholders (a "rip-off", according to Mr Yarrow), that prices have remained unjustifiably high and that last August's settlement by Professor Littlechild would generate even more profits for the industry. But it was not until Northern Electricity proposed handing out £500m in sweeteners to shareholders to fight off a hostile takeover bid from Trafalgar House that the man and woman in the street - and those at Westminster - gained an inkling of the size of the companies' cash reserves.
Views of what constitutes interference by regulators vary greatly. From the consumer's - as opposed to the City's - point of view, Professor Littlechild's decision this week was welcome. According to the National Consumer Council, some of the biggest gains for consumers have come in precisely in those industries where regulation has been "strongest" (ie most "intrusive") - gas, for instance, where prices have fallen by a third in real terms since the mid-1980s. Yet gas, unsurprisingly, has been the scene of some of the fiercest conflicts between industry and regulator, culminating in the desperate decision by British Gas two years ago to refer itself to the MMC - a move not unlike a turkey voting for Christmas.
Professor Littlechild's decision to review the price caps agreed last August, however, is "political", just as the decisions made 20 years ago by ministers in charge of nationalised industries were political. According to Mr Yarrow, Britain's system of regulation is in a "total mess", in large measure because the process has been "repoliticised". But, as he points out, regulation involves decisions "about the distribution of resources in the economy. In that sense it is inherently political and open to political agendas." The gain, compared with the bad old days of nationalisation, is arguably that such decisions are no longer party political.
Industry, however, may not appreciate such fine distinctions. Hence the calls for a "regulator of regulators", greater accountability and "transparency", a new select committee for regulated industries, more control by the MMC or the National Audit Office. The irony, of course, is that the more accountable and transparent regulation becomes, the more political it will be. Regulation always was an uneasy half-way house between monopoly and the free market. One day, when a fully liberated and deregulated market exists for electricity, water, gas and telecommunications, it may become unnecessary. Until then, we have to make the best of it we can.
