Why replace your boiler?
A new A-rated condensing boiler does far more than heat your home — it reduces bills, improves comfort and gives you years of reliable service.
A modern A-rated condensing boiler runs at 92–94% efficiency. Replacing a pre-2005 unit typically saves the average UK home around £340 a year on gas.
New boilers use modern electronics, self-diagnostics and higher-grade components — dramatically reducing the risk of mid-winter breakdowns.
Rooms warm up faster, temperatures stay steady, and every radiator delivers its full output. Winter mornings finally feel like they should.
Modern combis deliver higher flow rates for stronger showers, and system boilers with unvented cylinders provide mains-pressure hot water throughout the house.
Newer boilers run noticeably quieter thanks to improved fans, modulating burners and better acoustic insulation — no more kettling or banging pipes.
Wi-Fi thermostats, weather compensation and OpenTherm modulation come as standard, giving you fine control from your phone and typical 8–12% savings.
A more efficient boiler burns less gas for the same warmth — shrinking your household carbon footprint and helping the UK meet its net-zero targets.
Manufacturer-approved installations from Vaillant Advance and Worcester Accredited engineers unlock warranties of up to 12 years — real peace of mind.
Which boiler is right for your home?
Choosing the right type of boiler makes all the difference to comfort, efficiency and running costs. Here's a plain-English guide to the three main options — we'll always confirm the right choice for you during the survey.
- Space-saving — no cylinder or loft tank
- Instant hot water on demand
- Efficient — no stored water losing heat
- Faster, less disruptive installation
- Flow rate limited by mains pressure
- Not ideal for simultaneous multiple showers
- Higher-output units need larger gas pipe
- Excellent flow to multiple outlets simultaneously
- Mains-pressure hot water — strong showers throughout
- Compatible with solar thermal and heat pumps
- Faster hot water refill than heat-only systems
- Requires airing cupboard or utility space for the cylinder
- Hot water is finite — waits between long uses
- Slightly more complex than a combi installation
- Works well with older pipework and low mains pressure
- Simple, robust and easy to service
- Can supply multiple bathrooms with sufficient tank capacity
- Straightforward like-for-like replacement
- Requires loft tanks and airing cupboard cylinder
- Slower to warm up than combi or system boilers
- Larger overall footprint in the home

Get in touch by phone, email or online. We'll ask a few quick questions about your property and current heating so we can prepare properly.
One of our experienced engineers visits to inspect your existing system, gas supply, mains pressure and radiators — free of charge and with no pressure to proceed.
You receive a fully itemised, fixed-price written quote covering the boiler, all materials, labour, disposal and warranty. No vague estimates, no hidden extras.
We recommend the correct type, size and model of boiler for your home — matching output to your actual heat demand, not simply selling you the biggest unit.
Our Gas Safe registered engineers carry out the installation cleanly, tidily and to manufacturer specification. We protect floors and clear up thoroughly as we go.
The system is pressure-tested, flushed, dosed with corrosion inhibitor and commissioned to the boiler manufacturer's exact requirements.
Before we leave we walk you through your new boiler and controls — how the timer works, how to set the temperature, and how to check pressure.
We register your warranty with the manufacturer on your behalf and send you the paperwork for your records — usually up to 10–12 years' cover.
We remind you when your annual service is due, remain on hand for any questions, and offer priority repair support if anything ever goes wrong.

Frequently asked questions
How much does a new boiler cost?
The price varies depending on the type of boiler, brand, warranty length and any additional work needed — but a typical combi replacement in Brighton or Hove starts from around £1,895 fully fitted. System and heat-only installations, boiler-type conversions and premium models such as Vaillant Advance or Worcester Accredited cost more. We always confirm a fixed, itemised price in writing before any work begins — no vague estimates, no hidden extras.
Which boiler is best for my home?
It depends on your property size, hot water demand and existing pipework. Combi boilers suit most 1–3 bedroom homes with one bathroom, system boilers work best for larger homes with multiple bathrooms and hot water demand, and heat-only boilers are ideal for period properties on gravity-fed systems. During your survey we'll assess your home honestly and recommend the correct type — not simply the most expensive.
How long does installation take?
A straightforward combi swap is usually completed in a single day. A boiler-type conversion (for example, upgrading a heat-only system to a combi) typically takes 1–2 days. Larger unvented system installations may take 2–3 days. We give you a realistic timeframe upfront so you can plan around it.
Can I keep my existing pipework?
In most cases, yes — provided the pipework is in good condition and correctly sized for the new boiler. During the survey we inspect the gas supply, mains water pressure and existing radiator pipework carefully. If anything needs upgrading (for example, a larger gas pipe for a higher-output boiler), we explain why and include it in your fixed quote.
How efficient are modern boilers?
Every new gas boiler sold in the UK is a high-efficiency A-rated condensing boiler, running at 92–94% efficiency. That means almost every unit of gas is turned into useful heat — compared with 60–70% for a typical pre-2005 boiler. Replacing an old G-rated boiler saves the average UK home around £340 per year on gas bills (Energy Saving Trust).
Will I need a powerflush?
Not always. If your existing system is relatively clean and well-maintained, a magnetic filter and chemical flush is often sufficient. However, most boiler manufacturers require a system that's clean, flushed and inhibited to keep the warranty valid — so on older or sludged systems, a powerflush is highly recommended. We'll test water quality during the survey and give you honest advice.
What warranty will I receive?
That depends on the boiler you choose. Standard warranties usually run 5–7 years, but as a Vaillant Advance and Worcester Accredited installer we can offer manufacturer-backed warranties of up to 12 years on selected models. We register every warranty on your behalf and send you the paperwork for your records.
Do I need a magnetic filter?
Yes — and every one of our installations includes one as standard. A magnetic system filter (such as MagnaClean) captures iron-oxide sludge before it reaches your new boiler's heat exchanger, protecting the boiler for years and keeping efficiency high. It's a small component that dramatically extends system life and is required by most manufacturers to validate the warranty.
