BOILER REPLACEMENT

Your boiler is probably the single most important piece of equipment in your home, providing for your heating and hot water year-round.

As a rule, you can assume that it’s using up around 60 per cent of your energy costs.

You can expect a typical boiler to keep going for about 15 years – past that, you’re one of the lucky ones. So, if it’s old, unreliable or unable to cope with your needs, it might be time to budget for a replacement.

Despite the initial cost, there’s a good chance that replacing an older, inefficient boiler with a new model, combined with thermostatic radiator valves, will save you energy and money over time.

Why Staunch and Flow?

Staunch and Flow are London’s premier plumbers, offering a consistent service for central heating systems and boiler replacement. Our boiler engineers work to Gas Safe regulations (CORGI registered) and will replace any boiler across London.

Our team has over 100 years of boiler service experience collectively and have been chosen to participate in the Worcester Bosch partnership Business Initiative Scheme.

As a Which? Trusted Trader, our engineers will arrive on time, delivering the highest quality service every time.

Choosing The Right Boiler

There are a number of different issues to consider when deciding if now is a good time to make the change.

You will need to consider whether you need a new boiler or a replacement boiler and, if it is a new boiler, choose the type and specification of boiler that will best suit your needs.

Staunch and Flow recommend Vaillant boilers, because we can provide you with an 8-year guarantee and this brand is generally acknowledged to be reliable and one of the easiest to deal with should a repair become necessary.

We’ll be happy to discuss your requirements over the phone and, in many cases, if you can provide us with pictures via email that give us enough information, we can provide you with an estimate without calling out our assessor.

For more information, contact us at: 0208 964 6710 or follow this link to our page with full details of the ins and outs of choosing a boiler.
