How Much Does a Utility Room Cost in the UK? Complete Utility Room Cost Guide (2026)

A utility room is one of the most practical home improvements you can make. By moving washing machines, tumble dryers, boilers, and household storage out of the kitchen, a utility room helps keep your home organised while freeing up valuable living space.

Whether you're converting an existing room, transforming part of a garage, or creating a utility room as part of an extension, understanding the costs involved is essential before starting your project.

So, how much does a utility room cost in the UK in 2026?

This guide covers utility room installation costs, utility room conversion prices, fitted utility room costs, and the factors that affect your overall budget.

Average Utility Room Costs in the UK

The cost of creating a utility room varies depending on whether you are converting an existing space or building a completely new room.

Typical utility room costs include:

• Basic utility room conversion: £2,000 – £5,000
• Mid-range fitted utility room: £5,000 – £10,000
• Premium utility room installation: £10,000 – £20,000+
• Utility room as part of an extension: £15,000 – £50,000+

Most homeowners spend between £5,000 and £12,000 creating a fully functional utility room with fitted units, plumbing, and electrical work.

Utility Room Conversion Costs

The most cost-effective option is converting an existing room.

Common spaces used include:

• Spare rooms
• Underused dining rooms
• Large kitchens
• Garages
• Side returns

Typical conversion costs:

• Small utility room conversion: £2,000 – £5,000
• Medium utility room conversion: £5,000 – £8,000
• High-spec utility room conversion: £8,000 – £15,000+

Because the structure already exists, conversions are significantly cheaper than building new space.

Garage to Utility Room Conversion Cost

Many homeowners choose to convert part of their garage into a utility room.

Typical costs:

• Partial garage conversion: £3,000 – £8,000
• Full garage conversion with utility area: £8,000 – £20,000+

Additional costs may include:

• Insulation
• Flooring
• Heating
• New windows and doors
• Plumbing installation

Utility Room Extension Costs

If you don't have spare internal space, building a utility room extension may be the best option.

Typical costs:

• Small utility extension: £15,000 – £25,000
• Medium extension: £25,000 – £40,000
• Large utility extension: £40,000 – £50,000+

While this is the most expensive approach, it also creates additional floor space and can increase property value.

Fitted Utility Room Costs

Storage is often the biggest component of a utility room project.

Typical fitted furniture costs:

• Basic utility units: £1,000 – £3,000
• Mid-range fitted cabinetry: £3,000 – £6,000
• Bespoke utility room joinery: £6,000 – £15,000+

Popular features include:

• Tall storage cupboards
• Integrated laundry baskets
• Cleaning product storage
• Pull-out shelving
• Built-in ironing boards

Plumbing Costs for a Utility Room

Most utility rooms require plumbing work for:

• Washing machines
• Sinks
• Tumble dryers (where applicable)
• Water softeners

Typical plumbing costs:

• New sink installation: £200 – £800
• Washing machine plumbing: £100 – £500
• Utility room plumbing package: £500 – £2,000+

Costs increase if new water supplies or drainage runs are required.

Electrical Costs for a Utility Room

Utility rooms typically require several electrical additions.

Common installations include:

• Appliance sockets
• LED lighting
• Extractor fans
• Additional power points
• Under-cabinet lighting

Typical electrical costs:

• Basic electrical work: £300 – £1,000
• Full utility room electrical installation: £1,000 – £3,000+

Utility Room Flooring Costs

Practical, hard-wearing flooring is important due to moisture and heavy use.

Popular flooring options include:

Vinyl Flooring

Cost:

£20 – £60 per m² installed

Affordable, waterproof, and easy to clean.

Laminate Flooring

Cost:

£25 – £80 per m² installed

Provides a more premium appearance while remaining cost-effective.

Porcelain Tiles

Cost:

£50 – £150 per m² installed

Extremely durable and popular in high-end utility rooms.

What Affects Utility Room Costs?

Several factors influence the overall budget.

Room Size

Larger utility rooms require:

• More cabinetry
• More flooring
• Additional lighting
• Increased labour

This naturally increases project costs.

Existing Services

If plumbing and electrics are already nearby, installation costs are significantly lower.

Creating entirely new water, waste, and electrical connections can add thousands to the budget.

Bespoke Storage

Custom-built joinery and fitted cabinetry can dramatically increase costs compared to standard off-the-shelf units.

Appliances

Many homeowners choose to upgrade appliances when creating a utility room.

Common additions include:

• Washing machines
• Tumble dryers
• Washer dryers
• Wine coolers
• Additional freezers

Appliance costs vary widely depending on specification.

Does a Utility Room Add Value to a House?

Utility rooms are highly desirable among UK buyers because they:

• Reduce kitchen clutter
• Improve household organisation
• Provide additional storage
• Create dedicated laundry space

While utility rooms may not add huge amounts to a property's valuation on paper, they can significantly improve buyer appeal and help a property sell faster.

Do You Need Planning Permission for a Utility Room?

If you are converting an existing internal room, planning permission is usually not required.

However, planning permission may be needed if:

• You are building an extension
• The property is listed
• The home is located in a conservation area

Always check with your local planning authority before starting work.

Ways to Save Money on a Utility Room

To reduce costs:

• Convert existing space rather than extending
• Use standard cabinetry instead of bespoke joinery
• Keep plumbing close to existing pipework
• Reuse existing flooring where possible
• Compare multiple contractor quotes

Good planning can often reduce project costs substantially.
