Boiler installations & replacements

Boiler installations and replacements in Bristol

Old boiler breaking down, or no heating at all? We survey your home, give you the price before we start and fit a new boiler that suits it. The old one goes with us when we leave.

Why Bristol homes replace their boilers

Older houses, older boilers, bigger bills

A lot of Bristol's housing is Victorian and Edwardian terraces, and plenty of those have been split into flats. Their heating has usually been altered more than once: a boiler moved, a bathroom added, radiators bolted on over the years. The result is often a tired boiler working against a system it was never sized for.

Much of the water around Bristol is hard, too. Over a decade or more, scale and sludge build up in the heat exchanger and pipework, and the boiler works harder to deliver less heat.

A new, correctly sized boiler is more efficient, and it removes the cycle of call-outs for a boiler that keeps failing. We'll tell you honestly if a repair makes more sense, and quote for a replacement when it doesn't.

Signs it's time to replace, not repair

  • It's 10 to 15 years old and has needed repairs more than once
  • Radiators are cold at the bottom, or the water takes ages to heat
  • Gas bills have crept up with no change in how you use the heating
  • The boiler bangs, whistles or keeps losing pressure
  • An engineer has told you parts are getting hard to find

Three kinds of Bristol home, three different jobs

Bishopston, Redland, Southville, Bedminster

Victorian and Edwardian terraces

The boiler is often in a kitchen cupboard or cellar, with a flue running through a party wall. We plan the flue route so it stays clear of neighbouring windows and boundaries. Switching to a combi also means checking the gas pipe size and finding a drain for the condensate.

1930s semis and post-war houses

Usually a boiler in the kitchen or garage and a cylinder in the airing cupboard. These suit either a straight swap or a combi, and a combi frees up the loft tank and cylinder space. We'll go through how many people use hot water at once and recommend the one that fits.

Flats and conversions

Flue length and position are tightly limited, and a leasehold flat may need the freeholder's or managing agent's consent before work starts. We check both at the survey, so there are no surprises once the old boiler is off the wall.

How the job runs

From survey to handover, in five steps

You'll know what's happening and when at every stage. A straight swap is often done in a day. Moving the boiler or changing the type of system takes longer, and we'll tell you how long at the survey.

  1. We come and look

    We check the existing boiler, flue, pipework and radiators, and ask how you use hot water: how many people, how many bathrooms, any plans to extend.

  2. You get the price and the options

    Combi, system or regular, and what output you need. We explain the choice in plain English and give you the price before we start.

  3. Install day

    Floors and furniture are covered. We drain down, take out the old boiler, mount the new one and connect the flue, gas, water and condensate pipework.

  4. Flush, filter and commission

    We clean the system, fit a magnetic filter, add inhibitor and test for gas tightness. Then we commission the boiler and check every radiator.

  5. Handover

    We show you the controls and set the heating to suit your routine. We also notify the installation and register the manufacturer's warranty, then clear up before we go.

What affects the cost

Four things that change the price of a new boiler

No two houses are the same, so we don't quote from a price list over the phone. These are the things that move the figure up or down.

Boiler type and output

A combi, a system boiler and a regular boiler with a cylinder are priced differently. Output should match your hot water demand, and a larger family with two bathrooms needs more than a flat with one.

Whether the boiler moves

Fitting the new boiler where the old one was is the simplest job. Moving it to a loft, a different wall or downstairs means new pipework, a new flue route and more time on site.

The flue route

In tight terraces, a flue near a neighbour's window or boundary may need a plume kit or a vertical route to meet the regulations. A longer or more awkward flue costs more to fit.

Condition of the existing system

Radiators full of sludge, seized valves or tired pipework need attention before a new boiler goes on. A powerflush or a few new valves is cheaper than a new boiler failing early.

If we spot something at the survey that changes the job, we tell you then. You'll never find out on the day that the price has moved.

Access and parking

Getting the van, the new boiler and the old one in and out

Many Bristol terraces are on steep, narrow streets with resident permit parking. When you book, tell us where we can park and whether the boiler is in a cellar, loft or up a flight of stairs. A boiler is heavy and awkward to carry, so we plan the delivery and the removal of the old one around your street.

In flats, tell us about lift access, loading restrictions and any building rules on working hours. We'll fit around them.

Questions we get asked

New boiler questions, answered

Should I choose a combi or a system boiler for a Bristol terrace?

It depends on how much hot water you use at once. A combi suits most terraces and flats with one or two bathrooms, and it frees up the loft tank and cylinder space. A system boiler with a cylinder copes better with a larger household where showers run together. We go through your usage at the survey and recommend the one that fits.

How long does a boiler replacement take?

A like-for-like swap is often done in a day. Moving the boiler, changing from a regular to a combi, or fitting a new flue route takes longer. We'll confirm the time needed when we give you the quote.

Do I need to be at home while the boiler is replaced?

Someone needs to be there at the start to show us the boiler, the stopcock and where we can work, and again at the end for the handover. We'll agree the times when we book.

I live in a leasehold flat. Do I need permission?

You may do. Some leases and managing agents require consent before the boiler or flue is changed, and some limit working hours. Check your lease, or ask your managing agent, before the survey. We'll tell you what we need to see.

Where will you park, and does it matter?

It helps us to know. Many Bristol streets are narrow or have permit parking, and we need to get a heavy boiler in and the old one out. Tell us about parking when you book and we'll plan the delivery and the day around it.

Do you charge for coming out to quote?

No. There is no callout charge and the survey and quote are free. You get the price before any work starts, and we tell you about any changes before they happen.
