Homeowner Guide: How Buying a Boiler Supply-Only Can Save You Hundreds

Homeowner Guide: How Buying a Boiler Supply-Only Can Save You Hundreds

Dec 15, 2025

Replacing a boiler is one of the biggest home expenses a homeowner will ever face. But what many people across Prescot, St Helens, Knowsley, Huyton and Liverpool don’t realise is that you can save a significant amount of money simply by choosing to buy the boiler supply-only.


Instead of paying inflated package prices that combine the boiler, installation, extras and labour into one large bill, buying the boiler separately gives you full control over what you spend — and often results in hundreds of pounds saved.


As a trusted local merchant serving both public and trade customers, Prescot Plumbing & Heating specialises in supply-only boilers, helping homeowners get high-quality heating systems at the best possible price.


Here’s why buying your boiler supply-only is becoming the smarter choice.


💷 1. Transparent Pricing — No Hidden Installation Costs

When national companies advertise boiler replacements, the price usually includes:

  • The boiler
  • Installation
  • Labour
  • Call-out charges
  • System chemicals
  • Optional add-ons


This makes it difficult to know what the boiler itself actually costs.


By choosing supply-only, you pay only for the boiler you want — nothing more.

At Prescot Plumbing & Heating, we stock a wide range of affordable, energy-efficient boilers with clear, upfront pricing for both homeowners and local trades.

No upsells.


No inflated installation packages.

Just the boiler you need — at a fair price.


🔧 2. Choose Your Own Installer and Shop Around

With supply-only, you’re not tied into using an in-house installer. This allows you to:

  • Get multiple quotes
  • Compare local engineers
  • Choose someone you trust
  • Potentially reduce labour costs
  • Support local heating engineers in your area


Many local installers prefer customers to supply their own boiler because it keeps costs predictable and lets them focus on the installation itself.


Buying from Prescot Plumbing & Heating gives you the freedom to hire the right installer for your home and your budget.


🔥 3. Access to Trade Prices and Local Deals

Because we supply directly to both trade and public, homeowners often benefit from the same pricing that local heating engineers receive.


This means:

  • Lower boiler prices
  • Better choice
  • More competitive deals
  • No “middleman” mark-ups


For many Prescot homeowners, this alone can save £200–£500 on the cost of a new boiler.


🌡 4. Better Control Over the Brand and Efficiency Rating

When you buy a boiler through an installation package, you’re usually limited to whatever brand the company stocks.


But when you choose supply-only, you can:

  • Select the efficiency rating you want
  • Choose a trusted UK brand
  • Pick a boiler suited to your property size
  • Check warranty options
  • Make sure the model fits your long-term needs


At Prescot Plumbing & Heating, we stock a wide range of A-rated boilers suitable for:

  • Small homes
  • Terraced properties
  • Semi-detached houses
  • Large family homes
  • Multi-bathroom households


You get choice, clarity and full flexibility.


🛠 5. Long-Term Savings with Energy-Efficient Boilers

Because you’re not tied to an installation package, you can choose a boiler based on long-term running costs, not just the initial price.


A-rated boilers can reduce energy bills by:

  • Improving heat output
  • Reducing wasted gas
  • Providing smarter temperature control
  • Heating the home more efficiently


This means you save money every single month — not just at the point of purchase.


🧰 6. Everything You Need, All Under One Roof

When buying supply-only, you’ll often need accessories or maintenance products such as:

  • System inhibitors
  • Chemical flushes
  • Filters
  • Valves
  • Controls and thermostats


Prescot Plumbing & Heating supplies everything your heating system needs, making us the go-to merchant for both homeowners and trades across the North West.


You can collect everything in one visit — no online delays, no waiting for deliveries, no hassle.
