Boiler Installations in Bath Homes We Work In Every Week

Bath has some of the most varied housing stock in the country, from Grade I listed Georgian terraces to converted Victorian semis and modern purpose-built flats. We install boilers in all of them, every single week.

Georgian terraces are our most common job in Bath. Space is often tight, original pipework can be narrow or corroded, and flue routes need careful planning around windows, neighbours, and listed building considerations. We plan every job thoroughly before we lift a tool.

Victorian semis usually still have an old gravity-fed system, with a hot water cylinder in the airing cupboard and a tank in the loft. Upgrading these to a modern combi or system boiler means rerouting pipework, decommissioning the tank, and balancing the radiators so the whole house heats evenly. It’s a bigger job but we do it every week.

Flats need particular attention to flue positioning and building regulations. We always find a compliant route, whether that’s through an external wall, into a communal shaft, or up through a roof, and we deal with management companies and building managers directly where needed.

No loft? No issue. Cupboard installs and utility room boilers are routine for us. We work within tight spaces and always leave the area cleaner than we found it.

Bath neighbourhoods we cover

We fit boilers right across the city. A few of the areas we work in, and what we usually find there:

  • Bathwick — Georgian townhouses on Great Pulteney Street and Bathwick Hill, Victorian villas near the canal — much of it listed or in the conservation area.
  • Bear Flat — Edwardian and Victorian terraces on the slopes up Wellsway, solid stone and brick with period features.
  • Combe Down — Honey-coloured Bath stone cottages and Georgian and Victorian terraces high on the hill, with a village feel.
  • Lambridge — Victorian terraces and period villas along the London Road, much of it built well before modern insulation.
  • Lansdown — Grand Georgian terraces and crescents on the northern slopes, plus Victorian villas and newer homes higher up.
  • Larkhall — Victorian artisan terraces and cottages — tight spaces, solid walls and pipework that’s often decades old.
  • Newbridge — Mostly 1930s semis and terraces on the western edge of the city, many now ready for their next boiler.
  • Odd Down — Interwar and post-war family housing on the southern plateau, with plenty of heating systems that have done their time.
  • Twerton — Victorian and Edwardian terraces built for mill and railway workers, plus interwar, post-war and newer housing.
  • Weston — Georgian and Victorian stone properties in the old village core, with interwar and post-war semis further out.
  • Whiteway — Interwar and post-war semis and terraces on the hill above Twerton.
  • Widcombe — Georgian and Victorian terraces climbing the valley by the canal, much of it in the conservation area.

Also Oldfield Park and Southdown. Not sure we cover your street? Call or WhatsApp 01225 970248.

How Much Does a Boiler Installation Cost in Bath?

Most heating companies make you ask for a quote before they’ll tell you anything about price. We’d rather you knew roughly what to expect before you even pick up the phone.

  • Combi boiler swap (like-for-like): £3,000 to £4,000
  • System or regular boiler installation: £3,000 to £4,200
  • Back boiler conversion or full system upgrade: £3,500 to £6,000

$1 Every price includes a full system clean and a filter fitted, which the manufacturers require. These figures are a genuine guide, not a teaser rate to get you on the phone. The exact number always comes from a proper look at your home, and it’s fixed in writing before we start. No survey fee, no obligation.

What Happens When We Install Your Boiler

We know having someone work on your heating is a big deal. Here’s exactly what happens on the day so you know what to expect.

1. We arrive on time and protect your home
Dust sheets go down before anything else. We’re tidy workers and your home stays clean throughout.

2. We remove the old boiler
The old unit comes out carefully. We deal with draining the system and disposing of the old boiler, so you don’t need to do anything.

3. We install the new boiler
The new boiler goes in on the same day in most cases. We work methodically and don’t cut corners to save time.

4. Pipework adjustments if needed
If connections need altering or upgrading to suit the new unit, we handle that as part of the job.

5. System flush
We always check the system for sludge and debris. Where needed, we carry out a flush before connecting the new boiler, which protects it and keeps the warranty valid.

6. Full testing and commissioning
Every boiler we install is properly commissioned, with gas pressures set, controls configured, safety checks completed. This is what validates the manufacturer warranty.

7. We walk you through everything before we leave
We show you how the controls work, answer any questions, and leave you with all your paperwork, including the Gas Safety certificate and warranty registration.

Which Boilers Do We Install?

We only install boilers we’d put in our own homes. That means brands with a proven track record, long warranties, and parts that are available if something ever goes wrong years down the line.

Viessmann

Our primary recommendation. Viessmann is a German manufacturer with a reputation for build quality and efficiency that’s hard to argue with. They run quieter, last longer, and carry a strong warranty backed by the manufacturer. If you want the best boiler for your home and it to be as trouble-free as possible over the next decade, this is where we usually start the conversation.

Worcester Bosch

The most recognised boiler brand in the UK for good reason. Worcester Bosch are reliable and well-supported, and we’re happy to fit one if it’s your preference. We’ll confirm the warranty for your model in your quote. They’re a solid choice, particularly for straightforward combi replacements where you want a brand the homeowner already recognises and trusts. Parts are widely available and engineers who know them are everywhere, which matters for long-term peace of mind.

We will always recommend the right boiler for your home, not the most expensive one. When we quote, we’ll explain our recommendation and why.

Frequently Asked Questions

How long does a boiler installation take?

Most boiler installations take one day. If you’re moving the boiler, converting from a back boiler, or upgrading the system, it may take two days. We’ll confirm the exact timescale before we start.

Yes. We give you a written fixed-price quote before any work begins, and the price quoted is the price you pay. If anything unexpected comes up, we’ll stop and agree a price with you before carrying on.

Most boiler installations in Bath range from £3,000 to £6,000, depending on the boiler type, your home, and what’s involved. See the full breakdown further up this page. We give you a written fixed price before any work starts, no estimates that change on the day. The best way to get an accurate figure for your home is a free, no-obligation survey.

We install Worcester Bosch, Vaillant, Ideal, Baxi, and Viessmann. We’ll recommend the right boiler for your home based on what it actually needs, not the most expensive option. All come with full manufacturer warranty, and we only fit boilers we’d install in our own homes.

Up to 12 years on the Viessmann boilers we recommend: 12 years on the Vitodens 100-W and 10 years on the Vitodens 050-W. Other brands come with their own manufacturer warranty, which we’ll confirm in your quote. We register your warranty for you and explain what’s covered before we leave.

We cover Bath and surrounding areas within roughly 15 miles, including Keynsham, Saltford, Radstock, Midsomer Norton, Bradford on Avon and Frome, plus all Bath neighbourhoods. Not sure if we cover you? Call 01225 970248 and we’ll confirm straight away.

Older properties in Bath, like Georgian terraces and Victorian semis, are often best suited to a system boiler with an unvented cylinder, particularly if they have multiple bathrooms or high hot water demand. A combi boiler works well in smaller flats and houses with one bathroom where hot water demand is lower. We always survey the property first and recommend the right boiler for your home, not the most expensive one.

In most cases, yes. We offer next-day surveys across Bath and surrounding areas, and for straightforward like-for-like replacements, we can often install within 48 to 72 hours. If your boiler has broken down completely and you have no heating or hot water, call us on 01225 970248 and we’ll prioritise you.

Yes. Bath Eco Heat is fully Gas Safe registered and our registration number is 622049. You can verify this at any time on the official Gas Safe Register website. All of our engineers are individually registered and carry their Gas Safe ID cards on every job. We do not use unregistered subcontractors.

No. Every survey and written quote is completely free, with no obligation to book. We’ll look at your existing system, talk through your options, and give you a fixed price before you decide on anything.

We don’t offer buy-now-pay-later finance, but our Boiler Care Plan lets you spread servicing and cover costs monthly, and we’re happy to talk through payment options for the installation itself. Just ask when you call.

Yes. If you’re looking to move away from gas, we fit air source heat pumps as a straight swap for a boiler in plenty of Bath homes. It’s a bigger conversation than a like-for-like boiler swap, so we’ll talk through whether your home and budget suit it before recommending it. See our heat pump page for more.

If something unexpected turns up once we’re into the job, like corroded pipework we couldn’t see beforehand, we stop, explain what we’ve found, and agree a price with you before carrying on. You’ll never get a bill for work you didn’t agree to first.

Call or WhatsApp us and in most cases you’ll have a clear answer the same day. For a full fixed-price quote we’ll usually need a quick look at your system first. We offer next-day surveys across Bath, so you’re never left waiting around.
