Downpipe Repair Costs by Job Type (2026)
These are typical costs for a standard two-storey residential property with reasonable access. Prices assume the problem is above ground level at the downpipe itself.
| Job type | Typical cost | Duration |
|---|---|---|
| Clear a blocked downpipe | £60 to £150 | 30 to 90 min |
| Reseal a leaking joint | £60 to £100 | 30 to 60 min |
| Replace a cracked section (uPVC) | £80 to £180 | 1 to 2 hours |
| Replace a cracked section (cast iron) | £150 to £350 | 2 to 4 hours |
| Refix a loose bracket or clip | £40 to £80 | 30 to 45 min |
| Full downpipe replacement (uPVC) | £120 to £280 | 2 to 3 hours |
| Full downpipe replacement (cast iron) | £300 to £600 | 3 to 5 hours |
| High-pressure jetting (above ground) | £100 to £200 | 1 to 2 hours |
Most companies charge a minimum call-out fee of £50 to £80 regardless of the work done. Single-joint repairs or bracket refixing rarely justify a separate visit — batch these with a gutter clean if possible.
Is the Blockage Above Ground or Below?
This is the question that determines whether you are paying £100 or £400. Most downpipe blockages are at or just above the pipe outlet — leaves, debris and moss that have washed off the roof and compacted at the bend where the downpipe meets the drainage channel at ground level. These are cleared with a drain rod or high-pressure hose in under an hour.
The blockage is underground if:
- Water flows freely through the downpipe but pools around the downpipe shoe (the bend at the base) rather than draining away
- Multiple downpipes on the same property are blocked simultaneously
- The blockage clears temporarily after jetting but returns within days
- You can hear gurgling in other drains when water is poured into the downpipe
An underground blockage requires a drain cleaning specialist, not a gutter company. CCTV drain survey costs £100 to £250; drain jetting costs £150 to £300; more complex clearance (root intrusion, collapsed pipe) starts from £400. Ask the drain company explicitly whether they will provide a CCTV report showing the pipe condition before and after clearing.
Downpipe Replacement Costs by Material
The material of your existing downpipes affects both the cost of replacement and the options available to you.
| Material | Supply cost (per metre) | Fit cost (per metre) | Lifespan |
|---|---|---|---|
| uPVC (standard) | £4 to £8 | £30 to £45 | 25 to 40 years |
| Aluminium | £12 to £20 | £35 to £55 | 30 to 50 years |
| Cast iron | £35 to £80 | £60 to £120 | 50 to 100 years |
| Steel (galvanised) | £15 to £30 | £40 to £65 | 25 to 40 years |
Cast iron downpipes on Victorian and Edwardian properties can typically be replaced section by section in matching profile if the rest of the system is sound. When a single section cracks (usually at a joint corroded from inside), like-for-like replacement preserves the appearance without requiring a full system change. Matching profiles are available from several UK heritage suppliers.
Emergency Call-Out Premiums
A downpipe that is pouring water against the house wall during heavy rain qualifies as an emergency in most homeowners minds, but most gutter and roofline companies do not operate a genuine 24-hour emergency service. The realistic emergency options and their cost premiums:
- Same-day call-out (planned): 20 to 40 percent premium over standard rates. Available from larger companies with multiple vans. Book before noon for a same-day afternoon slot.
- Weekend or bank holiday rates: 25 to 50 percent above weekday rates. Most sole traders do not work weekends; regional companies charge accordingly.
- True emergency (same day, unplanned): Usually involves a drain emergency company rather than a specialist gutter cleaner. Expect £150 to £250 call-out plus labour at £80 to £120 per hour.
The practical advice: if your downpipe is blocked but not actively causing property damage, wait for a standard appointment. If water is actively saturating a wall or getting into the property, a temporary measure (a bucket at the shoe, reattaching a displaced pipe section) buys time before a standard call-out. See our guide on signs of blocked gutters to assess how urgent the situation actually is.
Repair vs Replace: How to Decide
A single cracked section on an otherwise sound system is always worth repairing rather than replacing. The cost difference is significant (£80 to £180 repair vs £120 to £280 full replacement) and a section replacement on a sound pipe takes under two hours.
Replace the full downpipe when:
- More than one section is cracked or failing, indicating age-related general deterioration
- The pipe has been patched more than once and is reaching the end of its useful life
- You are replacing the gutters or fascias at the same time (the scaffold and labour are already in place, the marginal cost of adding downpipe replacement is low)
- The existing profile is no longer available for like-for-like section replacement
