EVERYTHING YOU NEED TO KNOW
ABOUT BOILER INSTALLATION
Which Boiler Is Right for Your Home?
The right replacement boiler depends on your property size, hot water demand, and existing pipework. Combi boilers are the most popular choice for UK homes — they heat water on demand with no need for a separate hot water cylinder or cold water tank in the loft, making them ideal for properties with one or two bathrooms and excellent hot water pressure. System boilers suit larger homes with multiple bathrooms, storing hot water in a pressurised cylinder for simultaneous use across the house. Regular (heat-only) boilers are best for older properties with a gravity-fed system and a cold water tank in the loft. Back boilers, hidden behind fireplaces, are now obsolete and should be replaced with a modern combi or system boiler. Our boiler installation engineers will carry out a free home visit and full heating survey, assess your home's hot water needs, and recommend the most efficient and cost-effective replacement boiler for your specific property — then provide a personalised, fixed-price boiler quote you can trust.
How Much Does a New Boiler Installation Cost?
A new combi boiler installation starts from around £1,999 fully fitted — your replacement boiler installation price includes supply of the boiler, all labour, a Worcester Greenstar magnetic filter, Cal Mag scale reducer, chemical flush of the existing system, a free compatible room thermostat, carbon monoxide detector, old boiler removal and disposal, and Gas Safe certification. System boiler replacement installations typically start from £2,200–£2,800 depending on cylinder size and system complexity. Regular boiler replacements start from £2,400. Upgrading from a D-rated or G-rated boiler to a new A-rated condensing boiler could save you up to £300 a year on your heating bills. Prices vary based on the boiler model, system complexity, and any additional work required.

Boiler Brands We Install
As a Worcester Bosch Accredited Installer, we have the highest level of manufacturer training and certification for Worcester Bosch boilers — the UK's best-selling boiler brand. This accreditation allows us to offer extended warranties of up to 12 years on Worcester Bosch models, which no non-accredited installer can match. We are also experienced installers of Vaillant, Ideal, Viessmann, Baxi, and Glow-worm boilers. We'll always give you an honest recommendation based on your budget and hot water needs — not on which brand pays the highest margin.
Signs You Need a New Boiler
When should I replace my boiler? Your replacement boiler may be needed if it is over 10–12 years old and becoming unreliable; if it breaks down repeatedly and repair costs are mounting; if your energy bills have increased significantly without explanation; if it takes a long time to heat up or struggles to maintain hot water temperature; if it makes unusual noises such as banging, kettling, or gurgling; if it leaks water or shows visible corrosion; or if spare parts are no longer available. A G-rated boiler (pre-2005) or D-rated boiler can be up to 30% less efficient than a modern A-rated condensing replacement boiler — a new boiler installation could save hundreds of pounds per year on energy bills. If you're unsure whether to repair or replace your boiler, our engineers can advise during a free home visit.
What Happens on Installation Day?
Our boiler installation engineer will arrive at the agreed time and protect your floors and work area before starting. We'll drain down the central heating and hot water system, remove the old boiler, and make good any pipework as required — old boiler removal and disposal is included as standard. The replacement boiler is then fitted, the system is flushed with a full system water treatment and refilled with inhibitor, and all controls, smart thermostats, and Thermostatic Radiator Valves (TRVs) are commissioned and tested. We'll carry out a full gas safety check, issue your Gas Safe certificate, and register your boiler warranty with the manufacturer on the same day. Before we leave, we'll walk you through the controls and answer any questions. Most like-for-like replacement boiler installations are completed in 1–2 days; more complex system conversions typically take 2–3 days. A step-by-step guide to boiler installation is available on request.
Finance Options Available
A new boiler installation doesn't have to mean a large upfront payment. We offer 0% finance for 12 and 24 months through Phoenix Financial Consultants Limited (FRN: 539195) — meaning you pay no interest at all on those terms. For example, a £2,000 replacement boiler installation on 24-month 0% finance costs just £83.33 per month with no interest. Longer terms are also available. The ECO4 scheme may also provide free or subsidised boiler replacements for eligible low-income households — ask us for details when you book your free home visit. Finance is subject to status and credit checks. Ask us for a personalised new boiler quote including finance options when you book your free home visit.

NEW BOILER INSTALLATION GUIDE 2025
Everything you need to know about getting a new boiler installed in Hertfordshire or Buckinghamshire — from choosing the right type and brand to understanding costs and what to expect on the day.
WHAT TYPE OF BOILER DO YOU NEED?
Choosing the right boiler type is the most important decision in the process. The three main types of gas boiler available in the UK are combi boilers, system boilers, and regular (heat-only) boilers. Each suits different property types and hot water demands.
Combi Boiler
Heats water on demand. No cylinder or loft tank needed. Ideal for flats, smaller homes, and properties with 1–2 bathrooms. The most popular choice in the UK. Prices from £1,999 fitted.
System Boiler
Stores hot water in a pressurised cylinder. Suits larger homes with 2+ bathrooms where multiple taps run simultaneously. Faster hot water delivery than regular boilers. Prices from £2,200 fitted.
Regular / Heat Only
Works with a cold water tank in the loft and a hot water cylinder. Best for older properties with gravity-fed systems. Ideal if you have a solar thermal panel. Prices from £2,400 fitted.
Back Boiler
Hidden behind a fireplace. Now obsolete — no longer manufactured. If you have one, replacement is strongly recommended. We can convert to a modern combi or system boiler.
NEW BOILER INSTALLATION COSTS 2025
The cost of a new boiler installation depends on the type of boiler, the brand and model, the complexity of your existing system, and whether any additional work is required (such as relocating the boiler or upgrading pipework).

BOILER BRANDS — WHICH IS BEST?
The boiler market in the UK is dominated by a handful of brands. Here is an honest comparison of the main options we install:
Worcester Bosch — Our Top Recommendation
Worcester Bosch is the UK's best-selling boiler brand and has been rated the most reliable in independent surveys for over a decade. As a Worcester Bosch Accredited Installer, we can offer warranties of up to 12 years on their Greenstar range — the longest available in the UK. The Greenstar 4000 and 8000 ranges are our most popular installations. Worcester Bosch boilers are slightly more expensive than budget alternatives but the extended warranty and reliability record make them excellent value over the long term.
Vaillant — Premium German Engineering
Vaillant is a premium German brand with an excellent reliability record. The ecoTEC Plus and ecoTEC Pro ranges are popular choices for homeowners who want a high-quality boiler at a slightly lower price than Worcester Bosch. Vaillant warranties are typically 5–7 years with an approved installer. A strong choice for system boiler installations.
Ideal — Best Value
Ideal Logic and Vogue ranges offer good reliability at a more affordable price point. Warranties of 5–10 years depending on the model. A good choice for budget-conscious homeowners who still want a quality, A-rated boiler.
Baxi — Reliable Mid-Range
Baxi 600 and 800 series are reliable, well-priced boilers with 5–10 year warranties. Widely used in social housing and rental properties. A solid choice for straightforward combi boiler replacements.
SIGNS YOU NEED A NEW BOILER
Not sure whether to repair or replace? Here are the key signs that a new boiler installation is the right decision:
- Age: If your boiler is over 10–12 years old, replacement is usually more cost-effective than repeated repairs
- Frequent breakdowns: If you've needed repairs more than once in the past two years, the cost of repairs is likely approaching the cost of a new boiler
- Rising energy bills: A G-rated boiler can be up to 30% less efficient than a modern A-rated condensing boiler
- Slow to heat up: If your radiators take a long time to reach temperature, the heat exchanger may be failing
- Unusual noises: Banging, kettling, or gurgling sounds indicate limescale build-up, sludge, or a failing pump
- Leaks or corrosion: Visible water leaks or rust around the boiler are signs of serious deterioration
- Spare parts unavailable: If your boiler manufacturer no longer makes spare parts, repair is no longer viable
- Yellow or orange flame: The burner flame should always be blue — a yellow or orange flame indicates incomplete combustion and potential carbon monoxide risk
