How Much Does a New Boiler Cost in Wigan? (2026 Complete Guide)

If your boiler has broken down or you're planning ahead for a replacement, the first question on your mind is always the same: how much is this going to cost?

As Gas Safe registered boiler installers based in Hindley Green, Wigan, we fit new boilers across Wigan, Leigh, Bolton, St Helens and Warrington every single week. In this guide, I'll give you a straight, honest answer on what a new boiler costs in Wigan in 2026 — no fluff, no upselling.

New Boiler Prices in Wigan — 2026 Price List

At Lewis Heating & Plumbing, we operate fixed pricing — what we quote is what you pay. No hidden costs on the day. Here's our current fully installed price list for Wigan and surrounding areas:

Boiler Model	Size	Fully Installed
Worcester Bosch Greenstar 1000	24kW	£1,795

All prices above are fully installed, including removal of your old boiler, fitting the new unit, all pipework connections, flue, commissioning and Gas Safe certification. Nothing extra.

What Affects the Cost of a New Boiler in Wigan?

The boiler model is the biggest factor, but several other things can affect the final price:

1. The Size of Boiler You Need

Boiler output is measured in kilowatts (kW). A smaller home with 1-2 bathrooms typically needs a 24kW combi. A larger home with more bathrooms and radiators needs 30-35kW. We'll assess your property during our survey and recommend the right size — getting this wrong affects your heating bills for years.

2. Like-for-Like vs Conversion

A straight like-for-like combi boiler swap is the most straightforward and cost-effective installation. Converting from a back boiler, system boiler or heat-only boiler is more complex and takes longer, which affects cost. We'll always give you a fixed price before any work starts.

3. Flue Position and Length

Most standard installations use a horizontal flue through an external wall. If your flue needs extending, going through a roof, or requires extra bends, this can add to the cost. We'll spot this during the survey and include it in your fixed quote.

4. Additional Work Required

Occasionally additional work is needed — a magnetic filter, condensate pump, or pipework modification. We identify all of this during the survey so there are no surprises on installation day.

Can I Get Finance on a New Boiler in Wigan?

Yes. As an Introducer Appointed Representative of TradeHelp Ltd, we offer two finance options on Worcester Bosch boilers:

0% Interest Free Credit — Up to 24 Months

Pay nothing extra. Spread the cost of your new boiler over up to 24 months at 0% interest. This is our most popular option and means a Worcester Bosch Greenstar 1000 costs as little as £74.79 per month.

Low APR Credit — Up to 120 Months

For the lowest possible monthly payment, our 10.9% APR option spreads the cost over up to 10 years. A Worcester Bosch Greenstar 1000 costs as little as £28.78 per month.

Finance is subject to status and credit check, which must be completed before work starts. A 14-day cooling off period applies.

How Does Our Price Compare to British Gas?

British Gas typically charge between £2,500 and £4,000+ for a standard combi boiler installation — significantly more than our fixed prices. The difference? British Gas are a national company with large overheads. We're a local family business with lower costs and the same — if not better — quality of workmanship.

We're also Worcester Bosch accredited, which means we can offer the same manufacturer warranties as any other accredited installer. There's no advantage to using a bigger company for your boiler installation.

How Long Does a New Boiler Installation Take in Wigan?

A standard like-for-like combi boiler swap typically takes 4-6 hours and is completed in one day. We can usually survey and install within 24 hours of your first call, meaning you're rarely without heating or hot water for more than one day.
