Why replace

When is it time for a new boiler?

Boilers rarely fail politely. They tend to limp on for a year or two — needing the pressure topped up, making odd noises, costing more to run each winter — before they finally give up, usually on the coldest morning of the year. If your boiler is over ten years old, isn't a condensing model, or has needed more than one repair recently, replacing it is almost always cheaper in the long run than nursing it along.

A modern A-rated condensing boiler converts around 90% or more of the fuel it burns into useful heat, while older non-condensing boilers can waste a third of it. Over a heating season, that gap shows up clearly on your bills — which is why an efficient boiler is one of the measures the Energy Saving Trust highlights for cutting a home's heating costs.

The tell-tale signs

Frequent pressure loss, a pilot light that won't stay lit, radiators slow to warm, banging or gurgling, a faint smell, or rising bills with no change in usage — any of these is worth a free survey before winter.

How much does a new boiler cost?

A straightforward combi-to-combi replacement with Aspire starts from £1,750, fully fitted. Where the price goes from there depends on the type of system you have and what you're moving to.

  • Like-for-like combi swap — the simplest and most affordable job, often done in a day.
  • Conventional to combi conversion — removing the old tank and cylinder adds work, but frees up space and simplifies your system.
  • Boiler relocation — moving the boiler to a new spot adds pipework and time.
  • Brand and output — a larger home needs a higher-output boiler; premium brands like Worcester Bosch carry longer warranties.

We give you a fixed, written quote after a free survey — never a vague estimate over the phone. You'll know the exact price, the boiler model, and the warranty before you decide.

The brands we install

We're not tied to one manufacturer, so we recommend the right boiler for your home and budget rather than the one we're pushed to sell.

  • Worcester Bosch — consistently top-rated for reliability, with market-leading warranties.
  • Vaillant — German-engineered, quiet, and excellent value over its lifetime.
  • Ideal — strong performance at a keener price point, with solid warranty cover.

What to expect on installation day

Our Gas Safe engineer arrives at the agreed time, protects your floors and carpets, and removes your old boiler. The new unit is fitted, the system is flushed and pressure-tested, and your engineer talks you through the controls before leaving. Most combi swaps are finished the same day, and we register the warranty and notify Building Control on your behalf.
