Boiler installations and replacements in Filton

Your boiler struggling in a Filton semi or detached? We fit a new one sized for your home and heating needs, remove the old one, and leave everything running smoothly. Free survey, fixed price before we start.

Why Filton homes need new boilers

Post-war homes, ageing heating systems

Filton's housing stock is mostly 1950s and 1960s semis and detacheds. These were built solid, but the boilers fitted back then — or the ones bolted on in the 1980s — have long since run their course. A boiler that's 12 to 15 years old is usually past its best, especially if it's been patched up more than once.

Many Filton homes have a traditional heating setup: a boiler in the kitchen, a cylinder in the airing cupboard upstairs, and a tank in the loft. That works well, but means you're also paying to heat water that sits around. A modern combi boiler heats water on demand, cuts the energy bill and frees up cupboard space.

If you're still on the old system and deciding whether to repair or replace, we'll give you honest advice. A new boiler paired with modern controls can cut your heating costs by a quarter or more — and you get the 5-year guarantee built in.

Time to replace: the warning signs

  • The boiler is over 10 years old and has broken down twice in two years
  • It's making kettling sounds or losing pressure regularly
  • Your heating bills keep rising but your habits haven't changed
  • Radiators are slow to heat, or cold at the bottom
  • An engineer has said parts are hard to get hold of

Two Filton property types, two approaches

Filton, Southmead, Hengrove

1950s–70s semis and detacheds

Most have the boiler in the kitchen and a tank and cylinder in the loft. The flue usually goes straight out the wall or through the roof, which keeps things straightforward. We often fit a combi to cut costs and free up space, or stick with the existing layout if that suits your family better.

Filton Park, newer builds and extensions

Newer builds and extended homes

Fitted bathrooms upstairs and open-plan living mean you need instant hot water. A combi is usually the right choice here. If the house is bigger, a system boiler with a separate cylinder gives better flow at multiple taps. We check your setup at the survey and tell you which makes sense.

How we do a boiler installation

From the survey to handing you the controls

We turn up, look at what you've got, give you the options and the price in writing. Once you say yes, we fit the new boiler, test everything and show you how to use it. A straight swap takes a day. A bigger change takes a bit longer, and we'll tell you how long at the survey.

  1. Free survey

    We inspect the existing boiler, pipework, radiators and flue. We ask about your hot water habits and whether you're planning any changes to the house.

  2. Written quote, no surprises

    We explain your choices — combi, system, or a regular boiler with a cylinder — and give you the price before we start. That's it. Nothing added later.

  3. Fitting day

    We cover your floors and furniture. Old boiler drained, removed and taken away. New one fitted, all pipework and flue connected and tested for safety.

  4. System clean and commission

    We clean the heating circuit, install a magnetic filter to catch sludge, add inhibitor, and test everything. Every radiator is bled and checked.

  5. Handover and registration

    We show you the controls and how to adjust the heating. We notify the installation and register the warranty, then clear up before we leave.

What affects the cost

Four factors that change the price

Every Filton home is different, so we don't quote over the phone. These are the things that move the figure.

Boiler type and size

A combi, a system boiler or a regular boiler with a separate cylinder all have different costs. Size matters too: a small flat needs less output than a four-bedroom detached with two bathrooms.

Keeping it in the same place, or moving it

Fitting the new boiler where the old one hung is quickest and cheapest. Moving it to the loft, garage, or a different wall means new pipework, a new flue route and more time on site.

The flue route

Most Filton boilers flue straight out the kitchen or garage wall, which is straightforward. If a neighbour is close or regulations say the flue can't point at a window, we plan a different route. A longer or routed flue costs more.

The state of the system you're replacing

If radiators are full of sludge, valves are stuck or the pipework is tired, a powerflush or a few new valves before the new boiler goes in saves you trouble later and keeps the price fair.

If the survey finds something that changes the job, we tell you then and give you a revised price. No shocks once work starts.

Parking and access in Filton

Getting the van and boiler in and out

Filton's roads are mostly quiet residential streets with reasonable parking. Tell us when you book if there are any restrictions on your road, or if the boiler is in a loft, garage or down a narrow hallway. A boiler is heavy and bulky, so we plan the delivery and removal route to keep disruption to a minimum.

If you're in a new-build estate or there's limited drive space, we'll take that into account. Just let us know when you get in touch.

Filton boiler questions

Answers to what we're asked most

How long does a boiler installation take in Filton?

A straight swap of like-for-like takes most of a day, usually 6 to 8 hours. If we're moving the boiler, changing the type of system, or the existing pipework needs work, it may take a day and a half. We'll give you an exact timeframe at the survey.

Can we fit a combi in our 1960s semi?

Yes, most of the time. The gas pipe usually just needs checking to make sure it's the right size. The main thing is the water pressure — modern combis need mains pressure, which most Filton homes have. We check it at the survey and tell you straight away if there's a problem.

What happens to the old boiler and the tank and cylinder?

If you're switching to a combi, we remove the old boiler, cylinder and loft tank, drain them safely and take them away. If you're keeping a system boiler, we replace just the boiler. Everything is disposed of properly and recycled where possible.

Do we need planning permission or building control sign-off?

A boiler replacement doesn't need planning permission. Building Regulations apply, but as long as the boiler is Gas Safe approved and we're qualified to fit it, a sign-off is usually fast. We handle all the notifications and paperwork.

How do we know what size boiler we need?

We work it out at the survey. We ask how many people live in the house, how many bathrooms, how you use hot water and how big the rooms are. If you have a combi, we also check the water pressure. Then we recommend the output that fits your home and budget.

What's the guarantee on a new boiler?

All our new boiler installations come with a 5-year guarantee on the boiler and all the fittings we fit. Most boiler manufacturers also give a warranty — usually 5 to 10 years if the boiler is registered within 30 days of installation, which we do for you.
