NEWS - No Deal Brexit & Trans-European calls

Mobile phone roaming charges face immediate rise after March 29

Mobile roaming charges face an immediate hike if there is a No Deal Brexit, the government has confirmed.

Tory ministers are revoking the EU law which guarantees UK citizens pay the same for using their phone on the Continent as they do at home. That will leave mobile phone firms free to hike costs whenever they like after the UK leaves. Guaranteed free roaming launched across the EU just 20 months ago - and meant big savings. But that guarantee will be scrapped if there is no deal, thanks to an obscure law laid before Parliament this week. What is a No Deal Brexit? 21 ways you'll be affected if UK leaves EU with no deal The move will leave mobile phone firms free to hike costs whenever they like.

The current system caps the costs charged between EU and UK phone operators, letting them pass on the savings to customers. But the Mobile Roaming (EU Exit) Regulations admit these caps will have no legal force if there is no Brexit deal. That means phone giants could see their wholesale costs spiral, making roaming packages unaffordable and forcing them to push up costs, the government warns. Under the new rules, customers will still be prompted once they've spent £45 to prevent massive accidental bills. Travellers will also be prompted when they've hit 80% and 100% of their data allowance. But it will spell the end of 'guaranteed' free roaming across the EU, notes on the new law admit.

Costs are kept down by capping charges between different phone firms - but these caps would have no legal force after March 29 (Image: iStock Editorial) Alex Neill of consumer group Which? told HuffPost UK: Any return to sky-high charges for using mobile phones abroad would be a bitter blow for millions of consumers. The government should seek to avoid these charges by securing a deal with the EU. But if that is not the outcome, companies must be absolutely clear about any extra charges their customers could be facing.

Back when warnings first emerged about an end to roaming, the government insisted firms would not hike charges because of market competition. But MoneySavingExpert revealed last week that just two out of 12 major UK phone firms have guaranteed to keep free roaming in a No Deal Brexit . Most said they had no plans to raise charges - but stopped short of giving a cast-iron guarantee. Theresa May leaving Downing Street today for Brussels just 50 days before Brexit. Consumer groups lobbied the government to keep roaming free by law.

But after 'careful consideration' the government did not agree, because it would pass all the costs on to phone firms. That, in turn, could have pushed up the cost of mobile phone tariffs overall to compensate, an explanatory note to the new law says. Shadow Brexit minister Jenny Chapman said: These proposals prove that it will be holidaymakers and businesses that are forced to pay the price for this government's incompetence. It's unacceptable that these plans have been snuck out.

'Ministers need to start being straight with the British public about the consequences of no deal and take it off the table once and for all.' Shadow Brexit minister Jenny Chapman said: 'It will be holidaymakers and businesses that are forced to pay the price for this government's incompetence'

The anti-Brexit group Best For Britain branded the fiasco the 'Last Days of Roam' and claimed business travellers could be forced to pay £778 more per month. Lib Dem MP Layla Moran said: The cost of a hard Brexit on British travellers is becoming abundantly clear.

Typically, older types of conventional boilers only achieve efficiencies of 55% – 65%, meaning your high efficiency condensing boiler can save you over a third of your heating bills.

Whether you are looking for a combination boiler, system boiler or an open vent boiler, you will find the perfect product to suit your needs with Vaillants ecoTEC range.

As Vaillant boiler installation specaillists we want to be cost effective and efficient, we will keep your existing radiators cutting down on disruption, labor costs and time. (This dependant on radiator condition)

High efficiency combination boilers are becoming an increasingly popular choice in UK homes and now account for well over half of all new domestic boilers installed in Britain every year.

ecoTEC condensing combination boilers require no hot water cylinder or cold water storage tank, minimising the space they occupy. Vaillant’s range of combination boilers is broad enough o ensure the ideal solution for all house types - from a typical one bedroom/bathroom flat through to a four bedroom property with two bathrooms.

ecoTEC combination boiler

The ecoTEC combination boiler is a fully automatic, wall mounted, room sealed condensing (high efficiency) boiler for central heating and domestic hot water. Domestic hot water is supplied directly from the boiler, without requiring a copper cylinder, cold water tank, feed and expansion vessel and associated pipework. Domestic hot water has priority over central heating. The ecoTEC plus combination boiler consists of 3 models with outputs of 23 kW, 31 kW and 37 kW for domestic hot water and two pro versions with outputs of 24 kW and 28 kW for domestic hot water. All versions are available in natural gas. The ecoTEC plus 831 is also available in LPG. ecoTEC combination boilers incorporate a warm start facility that keeps the domestic hot water heat exchanger hot, providing an instantaneous delivery of domestic hot water. The temperature in the domestic hot water heat exchanger is limited by the boiler control system and it is not necessary to install a scale reducer on the cold mains to the boiler. However, in areas that get exceptionally hard water, a scale reducer may be fitted to prevent scale formation in the hot water system pipes. The heating system on ecoTEC plus combination boilers can be filled using the built–in filling loop contained within the boiler.

General Notes

The boilers have been designed for use with a sealed central heating system, and come fully tested and assembled with a built in circulating pump, expansion vessel and diverter valve (ecoTEC combination boilers).

The boilers are easily mounted on any internal wall and can be installed with either a horizontal or vertical RSF (room sealed fan assisted) flue. The boilers use a standard flue system (100 mm or 125 mm outside diameter). Flue extensions and additional bends and elbows are available for the flue system to Instructions for installation and servicing ecoTEC 5 increase the flexibility. If desired, an inhibitor may be used in the system. Guidance on the use of inhibitors is contained in these instructions. All boilers have a built in diagnostic system which indicates the operational status of the boiler. This feature provides key information to aid commissioning and fault finding. The data badge is fitted to the underside of the boiler. The Valliant ecoTEC are state-of-the-art appliances which have been constructed in accordance with recognized safety regulations.
