Why Replace Your Old Boiler?
If your boiler is over 12 years old, keeps breaking down, or your energy bills are climbing, a replacement boiler is almost always the smarter investment. Modern A-rated boilers are significantly more efficient than older models – converting more fuel into heat and reducing waste.
- Lower energy bills – modern boilers use less fuel to heat the same home
- No more unexpected breakdowns – new systems come with manufacturer guarantees
- Consistent heating and instant hot water when you need it
- Improved home value – an efficient heating system is a selling point
- Up to 12-year Worcester Bosch warranty – long-term peace of mind

Choosing the Right Boiler for Your Horsham Home
Every home has different heating and hot water needs. Our engineers will assess your property in Horsham and recommend the most suitable boiler type:
Combi boilers — most popular in Horsham homes
A combi boiler provides heating and hot water on demand from a single unit, with no separate water tank or cylinder needed. Ideal for smaller to medium-sized Horsham homes and properties with limited storage space. Most common boiler replacement in RH12 and RH13.
System boilers — for larger Horsham homes
System boilers work with a separate hot water cylinder, making them ideal for larger Horsham homes or properties where multiple showers or taps are in use at the same time. Faster hot water than a regular boiler without the need for a cold water tank in the loft.
Regular (conventional) boilers — for older Horsham properties
Regular boilers require both a hot water cylinder and a cold water tank, making them suitable for Horsham homes with older radiator systems or those already set up for this type of system. We can advise whether upgrading to a combi or system boiler makes sense for your property.

Boiler FAQ's
Yes, modern boilers are much more energy efficient than older models, using less fuel and leading to noticeable reductions in heating bills.
Absolutely. We provide flexible financing with interest rates starting from 0%, making upgrading to a new boiler more manageable.
Most installations are completed within a day, depending on complexity. We’ll provide an accurate timeframe during consultation.
The best boiler depends on your home size, hot water usage, and available space. We offer combi, system, and regular boilers and can recommend the most suitable option.
If your old boiler breaks down frequently, causes higher bills, or struggles to heat effectively, it’s time for an upgrade. Boilers typically last 10-15 years, so if you need a new boiler within that range, consider replacement.
We service Horsham and larger neighbourhoods including Broadbridge Heath, Southwater, Billingshurst, and Pulborough. We also cover towns and villages surrounding Crawley in West Sussex, East Sussex and Surrey.
