Boiler installations & replacements

Boiler installations and replacements in Keynsham

A boiler that's losing pressure, struggling to heat radiators, or simply too old to trust? We'll survey your home, explain your options and give you a fixed price before we start work.

Why Keynsham homes need new boilers

Modern homes, old heating systems

Keynsham's mix of 1960s and 70s semis, detached homes and bungalows often have boilers that were fitted when the house was built or shortly after. A boiler that's 15 or 20 years old doesn't just cost more to run — it's working harder than it should, and parts can be difficult to source when something fails.

Many of these homes also have the boiler in the garage or a kitchen cupboard, with the hot water cylinder hidden away in the loft or an airing cupboard. A modern combi boiler can simplify that setup, free up space and cut the annual servicing hassle.

We're honest about whether your boiler can be repaired cheaply or whether replacement makes sense. If it's beyond economic repair, we'll walk you through the options and quote for the right boiler for your home size and hot water needs.

When replacement beats repair

  • The boiler is over 12 years old and has had more than one call-out in two years
  • It's losing pressure, or the pilot light keeps going out
  • Radiators won't heat evenly, or take ages to warm up
  • The annual service bill is climbing, or the engineer warns parts are becoming scarce
  • Your heating is erratic — some days fine, other days not

Three types of Keynsham property, three different jobs

Somerdale, Ashton Park, newer estates

1960s and 70s semis and detached homes

These usually have a boiler in the kitchen or garage and a cylinder upstairs. A straight swap works fine, but many owners prefer a combi to lose the tank and cylinder. We'll check the mains pressure and gas pipe size to make sure a combi suits your household and how you use hot water.

Village properties, outlying areas

Bungalows and single-storey homes

The boiler is often in a utility room or side passage, which gives us good access and straightforward flue routing. We can usually fit the new one in the same spot without disruption, and the job is typically finished in a day.

Town centre terraced properties

Older terraced cottages and townhouses

Where a boiler sits in a tight kitchen or needs a flue past neighbours' windows, we plan the route carefully to meet regulations and avoid complaints. Sometimes a longer or vertical flue is the answer; we work that out at the survey and tell you what it costs.

How the installation runs

From survey to heating, step by step

You'll see what's happening at every stage. Most boiler swaps take a day. If the boiler moves or the system needs work, we tell you how long at the survey visit.

  1. The survey

    We look at the boiler, the flue, radiators and pipework. We ask about your hot water use and whether you've thought about changing the system type (combi, system or regular).

  2. Your written quote

    No surprises. You get the price, what's included, and the choice of boiler. We explain the difference between a combi, a system boiler and a regular setup in plain terms.

  3. Installation day

    We protect the floors and furniture. Old boiler drained, removed and disposed of. New boiler mounted, connected to gas, water, flue and condensate drain.

  4. System clean and commission

    We flush the heating system, fit a magnetic filter and add inhibitor to keep rust and sludge down. Gas tightness test, boiler commission, and we check every radiator heats.

  5. Handover and tidy-up

    We show you the controls, set the thermostat and explain the warranty. We register the installation with the manufacturer and leave the place spotless.

What changes the price

Four factors that affect your boiler installation cost

We don't give quotes over the phone because every home is different. These are the main things that move the price.

The boiler type and size

A combi is priced differently from a system boiler or a regular boiler with a hot water cylinder. The output also matters: two people and one bathroom need less than a family with two bathrooms in constant use.

Whether the boiler stays put

Fitting the new boiler where the old one is costs less. Moving it to a garage, a utility room or a different wall means new pipework, a new flue route and more labour.

The flue route

In terraces, the flue direction may be restricted by neighbours' windows or building boundaries. A plume kit or a vertical roof flue takes more work and affects the price.

The condition of your heating system

If radiators are full of sludge or valves are seized, we can powerflush the system or replace valves before fitting the boiler. That costs more but saves problems later.

We tell you at the survey if anything unexpected comes up and affects the price. No shocks on the day.

Access and parking in Keynsham

Getting the van and the boiler to your home

Keynsham's residential roads are mostly wide and straightforward. Parking is rarely a problem, and driveways give good access to front doors and garages. When you book, just let us know where the boiler is (kitchen, garage, utility room) and whether we need to carry it up or down stairs. We'll plan the delivery of the new boiler and removal of the old one to suit your home.

If you're in a terraced property with a narrow passage or side access, we'll work out the best route at the survey.

Questions we're asked

Boiler installation FAQs

How long does a boiler installation take?

A straight swap — fitting the new boiler where the old one was — usually takes one day. If the boiler moves, the flue route changes, or the system needs powerflush or new valves, it can take two days or occasionally longer. We'll tell you how long when we survey the home.

What's the difference between a combi, a system boiler and a regular boiler?

A combi heats water on demand and removes the need for a cylinder or tank, so it saves space. A system boiler heats a cylinder of stored hot water and is good if you have two bathrooms in use at once. A regular boiler works with a hot water cylinder and a loft tank — it's the traditional setup. We'll explain which suits your household size and hot water use at the survey.

Do you need planning permission or Building Regulations approval?

Most boiler replacements are considered maintenance and don't need planning permission. Changing the flue location, moving the boiler significantly, or altering the heating system may trigger Building Regulations. We'll check this at the survey and handle the notification if needed.

What warranty does a new boiler come with?

Manufacturers typically offer 5 to 10 years on the boiler itself, depending on the model. We also give a 5-year guarantee on our fixtures and fittings. If you register the warranty correctly (which we do), it may be extended. Check the boiler documents for the full terms.

Can I have a new boiler fitted on the same day we request a quote?

Not usually — we survey first to understand your home and heating needs, give you a fixed price, and then arrange an installation date. Most customers wait 5 to 10 days. If it's an emergency and your boiler has failed, call us and we can often fit an emergency repair or a quick replacement; call {phone}.

Is there a callout charge for the survey?

No. The survey and quote are free. You only pay if you go ahead with the installation, and the price we quote is the price you pay — no surprises.
