Pond Maintenance & Repair Cost UK 2026
A professional pond maintenance visit costs £100–£300, a full seasonal clean-out £150–£400, and the two common repairs — pumps and liners — run £150–£450 and £300–£1,000 respectively. In a drought summer, topping up from a butt keeps a pond legal and alive.
Pond & water feature costs — 2026
Typical garden ponds up to ~10,000 litres. Koi ponds and large water features carry specialist pricing above these ranges.
| Job | Typical cost | How often | Notes |
|---|---|---|---|
| Maintenance visit | £100–£300 | 2–4x a year | Debris, filters, water checks |
| Full clean-out | £150–£400 | Every 2–3 years | Drain, clean, restock water |
| Pump replacement | £150–£450 | As needed | Pump plus fitting |
| Filter / UV clarifier | £100–£350 | As needed | Green-water cure |
| Liner repair | £100–£300 | As needed | Patchable leaks only |
| Liner replacement | £300–£1,000 | 15–25 years | Full drain and rebuild of edges |
| New wildlife pond (small) | £1,500–£5,000 | — | Dug, lined, planted |
Indicative 2026 UK prices, compiled from published installer pricing (Checkatrade, MyJobQuote, MyBuilder and BookaBuilder cost guides, August 2026). BestBuilders has no quote history in this category yet, so treat these as a budgeting guide and confirm against three written quotes.
What changes the cost
| Cost factor | Typical impact | Why it matters |
|---|---|---|
| Pond size | the base variable | Litres decide pump size, chemical doses and how long every job takes |
| Fish stock | +20–50% | Koi and heavily stocked ponds need holding tanks and water-quality care during any work |
| Access to power and water | +£80–£250 | Pumps need an outdoor circuit; a distant tap slows a clean-out |
| Leak diagnosis | £80–£200 | Finding where a pond loses water is its own job before any repair is priced |
| Drought rules | worth knowing | Hosepipe bans exempt topping up ponds with fish in most regions - stored rainwater is the safe route regardless |
| Electrics | Part P applies | New outdoor circuits for pumps are notifiable - use a registered electrician |
Pond maintenance cost by UK region — 2026
Modelled from regional labour rates rather than measured in this category - materials cost much the same everywhere, the labour does not.
| Region | Typical installed cost | vs UK average |
|---|---|---|
| London | £130–£380/visit | +25–30% |
| South East | £120–£350/visit | +15–20% |
| South West | £100–£320/visit | +5% |
| Midlands | £100–£300/visit | baseline |
| North England | £90–£280/visit | −5–10% |
| Scotland | £90–£270/visit | −10% |
| Wales | £90–£270/visit | −10% |
| Northern Ireland | £80–£260/visit | −15% |
Getting it priced properly
1. Know your litres
Length x width x average depth x 1,000 gives litres - every quote question starts there.
2. Time clean-outs for autumn
Draining a pond in spring wrecks the breeding season; September is kindest to wildlife and easiest to book.
3. Fix the cause of green water, not the symptom
Algae is sunlight plus nutrients. A UV clarifier treats it; plants and shade prevent it - a good pond firm prices both routes.

Pond equipment brands compared: Oase, Hozelock, Blagdon, Pontec and Evolution Aqua
Pond quotes name pump and filter brands, and the spread is wide - a pump is a thing that runs 24 hours a day for years, so build quality shows up in the running, not the buying.
| Brand | Known for | Ranges you will be quoted | Typical unit price | Worth knowing |
|---|---|---|---|---|
| Blagdon | UK pond care brand | Amphibious IQ, Minipond, treatments | £40–£250 | Also the shelf name for water treatments and test kits |
| Evolution Aqua | Koi-grade filtration | Nexus, K+ pumps | £300–£2,000 | What koi keepers fit; overkill for a wildlife pond |
| Hozelock | Retail pond range | Aquaforce, Bioforce, EasyClear | £60–£300 | EasyClear all-in-ones suit small ponds - pump, filter and UV in one unit |
| Oase | German pond engineering; the premium name | AquaMax Eco, BioSmart, FiltoClear | £120–£600 | AquaMax Eco pumps are the long-run efficiency benchmark |
| Pontec | Oase's value line | PondoMax, MultiClear | £50–£200 | Oase engineering at entry prices; shorter warranties |
Prices above are for the pump or filter only — fitting is separate and is priced in the table further up this page. Brands are listed alphabetically, not ranked: BestBuilders does not sell or endorse any of them.
Pond & water feature — frequently asked questions
Around £100–£300 per visit for a typical garden pond, with most ponds wanting two to four visits a year. Annual contracts price the season slightly cheaper than ad-hoc call-outs.
£300–£1,000 for most garden ponds - the liner itself is cheap, the labour of draining, holding any fish, rebuilding edges and replanting is the bill.
Evaporation first - in a 2026-style summer a pond can honestly lose 5cm a week. Past that, the usual suspects are a leaking waterfall course, a punctured liner, or a failed seal at the pump housing. Diagnosis is typically £80–£200.
Most water companies exempt topping up ponds where fish welfare is at stake, but rules vary by company - and stored rainwater from a butt is better for the pond anyway, ban or no ban.
