How Much to Replace Guttering?
The average cost of replacing and installing new guttering is usually in the range of £450-£700 depending upon the condition of your fascias, whether the roofline has easy access, and whether your house is detached, semi or terraced.
Most roofline workers operate in pairs and will usually charge around £200-£300 per day. Usually, to replace your guttering it takes just a single day, maybe even less if only a ladder is needed.

New Guttering Prices
Here are a few average costs for installing new PVC guttering. Please note that these are average prices and, for example, you may notice that having new guttering installed on a detached bungalow is cheaper than a detached house.
This is simply because some houses don't have easy access, requiring an access tower to be built to complete the gutter replacement.
| House Type | House Size | Avg. Cost | Duration |
|---|---|---|---|
| Detached | Bungalow | £500 | 1 day |
| Semi-Detached | Bungalow | £450 | 1 day |
| Detached | 2-storey | £600 | 1 day |
| Semi-Detached | 2-storey | £500 | 1 day |
| Terraced | 2-storey | £450 | 1 day |

Guttering Replacement Cost Example
Assuming a typical semi-detached UK property with around 15 to 20 metres of guttering in total plus 3 rainwater downpipes. Then the typical cost for replacement would be around £600 to £800.
This would include erecting access equipment to work at height, the removal of existing guttering and rainwater downpipes, the supply and fit of new uPVC rainwater guttering, brackets and downpipes, connecting into existing drains, and then the removal of all waste material.
This figure will vary if you have an unusual roof design requiring many more brackets to support the guttering, or if there are access problems due to a conservatory or porch.
For a standard 3-bed semi, the job should take less than one day to complete. If you require cast iron guttering to be fitted then expect to pay a lot more.
Factors That Impact Gutter Replacement Costs
There are some factors to be aware of when replacing gutters that might increase costs. Some of them you have some control over, but others will simply be a result of your particular situation.
- Replacement gutter material
- Extent of guttering damage
- Length of guttering to be replaced
- Height and accessibility of guttering
- Regional price differences
What Installing New Guttering Involves
Installing new guttering is a job that will eventually need doing on all properties as the guttering takes some serious abuse dealing with the typical British weather while taking water away from the roof.
Plastic guttering is the most common type today as it is so versatile and can look exactly the same as cast iron guttering once installed. Removing the old guttering and fitting new replacement gutters and downpipes is relatively straightforward, but it does involve working at height so safety is paramount.
The guttering itself is fixed to the fascia board, so the removal of the guttering is often part of replacing the fascia and soffit boards (roofline). It therefore makes sense to replace the roofline products at the same time if required.
DIY Guttering Replacement
If you need to replace your guttering and plan to do the job as a DIY project, then you'll find new plastic guttering is by far the easiest type to fit.
To find out how much guttering you will need, simply measure all the way round your house then check the manufacturer's guidelines to estimate how many fittings you will need.
Remove Old Guttering
The first step is to remove the old guttering, plastic guttering is pretty easy to remove, but cast-iron guttering is heavy and the edges can be really sharp if corroded or worn, so if you have cast iron guttering then it will be a two-person job (at least).
Before you begin, ensure you are comfortable working on ladders at height and remember never to rest your ladder on the guttering.
You need to stop the old guttering from falling to the ground when removed, so place netting underneath or hammer nails into the fascia to catch it, then lower them slowly to the ground. Remove all sections and then the downpipes one section at a time from the top.
Fit New Guttering
Start fitting the new guttering with the outlet part for the downpipe first which you'll need to place directly over the drain.
You will need to use a plumb line to ensure you are directly over the drain. Fit the rest of the guttering with a slight fall of around 10mm every 6m of gutter to help the water drain efficiently.
If there is damage to a single section of guttering, then just that section can be replaced, there is no need to replace all the guttering if the rest of it is in good condition with no leaks.
Potential Pitfalls
You may find that the fascia board is damaged when removing the old guttering due to weathering or rot over the years, or you may inadvertently damage it when unscrewing the old gutter brackets.
So rather than fitting new guttering to rotten boards, you may find you have to replace all the roofline products at the same time, adding considerably to the overall cost.
In addition, the removal of the fascia boards may also damage the bottom roof tiles, so budget for replacing some of those also.
Why You Might Need to Replace Gutters
Gutters play a major role in protecting the structural integrity of your home, so keeping them in good working order can pay off in the long run.
Broken or blocked gutters can lead to rain penetrating the fabric of a property, potentially causing structural damage and even health issues if the problem isn't resolved quickly enough.
Blocked gutters can be caused by:
- Leaves and other debris from trees.
- Moss build-up.
- Dead birds or animals.
- Broken roof tiles.
Some of these issues may be solved by replacement gutters, but some might require extra intervention.
For example, if there are broken tiles on your roof, you'll need to fix that problem to stop water from getting into your home. With the cost to replace roof tiles usually starting from around £75 for a small repair, this could add to your overall costs.
Similarly, you may need to consider the roof moss removal cost to prevent future issues with moss growth or look at the cost of installing gutter guards if leaves are a persistent problem.
Guards won’t stop all debris but they will keep the larger pieces from causing blockages and adding extra weight which could cause sagging and strain on the brackets.
Leaking Gutters
Leaking gutters are one of the most common causes of isolated damp in UK homes and often result simply from general wear and tear, but blockages certainly exacerbate the problem.
If you do find damp in your home, one of the first things you should check is your guttering.
From the ground, the things to look out for include:
- Water running down the walls when it's raining.
- Stains or streaks on exterior walls.
- Peeling paint around fascia boards.
- Eroded soil at the base of the property.
- Noisy gutters.
It's also possible your gutters will be noticeably sagging. This is usually caused by the gutter becoming weighed down with debris and standing water, and/or rusty old screws and failing support brackets.
Ideally, you or a professional should check gutters regularly to see if there are any problems that may cause leaks later on.
The typical gutter repair cost is between £120 and £180, so you can save yourself some money on another replacement further down the line.
How to Fix Damaged or Blocked Gutters
If you have damaged or blocked guttering and are not confident you can do this job yourself safely, you need to call in the professionals and they can take care of everything from clearing debris to repairing plastic gutter brackets.
They'll use a special ladder to reach the roof and they'll start by removing any big pieces of debris from the gutter then they'll use a wire tool to clear the downpipes if required.
They will also replace any faulty sections of guttering and fill any cracks with sealant. Alternatively, if there is a lot of damage, they will just replace the guttering completely as this is actually cheaper than doing lots of small repairs!
Aluminium vs Plastic Guttering
Plastic gutters are cheap and will keep down the costs of weather-proofing your home down. However, they aren't as robust as metal so you may need to replace them more often. Plastic guttering also does not have a lot of options in terms of finish or colours. Aluminium guttering is aesthetically pleasing, particularly on period houses but is more expensive.
Aluminium gutters had fallen out of favour in the UK with cheaper plastic guttering being the most popular option, but there has been a recent surge in their popularity as buyers realise the money saved using plastic is a false economy due to the longevity of aluminium.
But if you just want a job finished quickly and as cheaply as possible, perhaps if on a limited budget or are intending to sell the property, then plastic gutters will do just fine. Aluminium guttering is certainly the favoured material amongst professional roofers and roofing contractors for guttering as they know the advantages of aluminium and how durable it can be.
FAQs
If the gutter is leaking/overflowing near the downpipe then most likely the downpipe is blocked and will need to be cleaned out. However, if there are multiple leaks without apparent blockages, chances are the seals are all failing or the guttering is so fragile it is starting to crack, in which case you will need new guttering! Temporary fixes can be tried using mastics and sealants but these temporary fixes only last a year or so before the leaks start appearing again.
Cast iron gutters should last 100 years or more if they were originally installed correctly, repairing cast iron gutters often requires metal work or even welding, so is best left to experts.
However, if low maintenance is a priority, then UPVC is the way to go, as cast iron gutters need regular cleaning and painting for a long lifetime, whereas with plastic you can just fit and forget, barring removing debris etc twice a year to prevent blockages.
If you do need to hire scaffolding, double check your tradesman has included the cost in the quote as it can add upwards of £300 to the overall cost of gutter replacement.
