What is the average cost to plumb a new kitchen in 2026?

A standard kitchen renovation in Exmouth typically costs £800 to £1,400 in plumbing labour and materials. This covers re-routing pipework, fitting a new sink and tap, plumbing in a dishwasher and washing machine, and disconnecting and reconnecting a gas hob. Premium installs with boiling water taps or additional appliances run £1,400 to £2,500 and up.

Is it cheaper to keep the sink in the same place?

Yes, significantly. Keeping the sink in its existing position saves £200 to £500 in waste pipe re-routing and reduces overall plumbing time by half a day. If your new kitchen layout works with the existing sink position, take it — the savings are substantial and the plumbing is much less disruptive.

Do I need a separate budget for boiling water taps?

Yes. A Quooker or Fohen boiling water tap is a separate line item — typically £400 to £1,200 for the tap itself, plus £200 to £400 for installation including a new electrical socket if one is not under the sink. Filters cost £40 to £80 every 6–12 months and CO2 cartridges (for sparkling models) cost £20 each.

Should I supply the materials myself?

For taps, sinks and appliances — yes. You will save 20–50% versus buying through the plumber or kitchen showroom. Just buy them in advance so the plumber has everything on day one. For pipework, fittings and sundries, let the plumber supply — they get trade prices and know exactly what is needed.

What is the difference between first fix and second fix plumbing?

First fix is the rough-in work — running new pipework to the right positions, capping off old supplies and preparing for units. It happens once the old kitchen is stripped and before new units go in. Second fix is the final connections — fitting sink, taps and appliances once worktops are in place. Both are essential for a kitchen refit.

Can I save money by doing some of the work myself?

Yes, if you are honest about your skills. The strip-out (removing old units and disconnecting appliances) is low risk and can save £150–£300 in labour. Painting, tiling and assembling flat-pack units are also DIY-friendly. Plumbing, gas work and worktop fitting are where pros earn their money — DIY mistakes here cost more to fix than the labour saved.

Line-by-Line Cost Breakdown

Use this as a checklist when comparing quotes. A good plumber's quote will itemise these costs separately.

Item	Typical Cost	Notes
Plumber labour (1–2 days)	£400–£800	Bulk of any renovation plumbing bill
New sink (stainless steel)	£60–£150	Granite composite or ceramic costs more
Sink (granite composite or ceramic)	£200–£500	Heavier — may need extra cabinet support
Mixer tap (mid-range)	£80–£200	Brushed steel or chrome
Pull-out or pull-down spray tap	£150–£350	More moving parts, slightly higher fail rate
Boiling water tap unit	£400–£1,200	Quooker, Fohen, Insinkerator, Grohe Red

The Hidden Costs Most Homeowners Forget

These four extras catch people out every time — budget for them up front.

Electrical work for boiling taps

A boiling water tap needs a dedicated 13-amp switched fused spur under the sink. If one is not already there, an electrician will charge £80–£200 to fit it. Budget for this separately.

Gas hob disconnect and refit

Often forgotten in renovation budgets. A Gas Safe engineer will charge £100–£200 to disconnect during the strip-out and reconnect once worktops are in. Book early — Gas Safe engineers fill up fast.

Tiling and worktop holes

Your plumber does not cut worktop sink holes — that is the kitchen fitter or worktop supplier. If the tap hole position changes, the worktop may need refabricating, which can cost hundreds.

Waste pipe re-routing

Moving the sink to a new wall can mean a longer waste run with less fall. If the pipe needs boxing in or going through a structural wall, expect £150–£400 in addition to standard labour.

Seven Ways to Save Without Cutting Corners

None of these tips compromise the quality of the finished kitchen — they just trim the bill.

Keep the sink in the same position to avoid waste pipe re-routing
Supply your own fixtures from a builder's merchant rather than the kitchen showroom — markups can be 30–50%
Get three written quotes that itemise labour and materials separately
Book a Gas Safe engineer in advance to avoid emergency callout rates
Do the strip-out yourself if you are confident — save the plumber's time for skilled work
Reuse appliances if they are under five years old rather than replacing for the sake of it
Skip the boiling water tap if your kitchen is small — a good kettle costs £40, the tap costs £1,000+ over its life with filters
