You may already have a list of jobs in mind: a new kitchen, updated bathroom, fresh electrics, replastering, flooring, decorating, or perhaps a complete overhaul of a dated property. The difficult part is often working out what all of that could realistically add up to before you start speaking to builders.

When looking at house refurbishment costs in the UK in 2026, there is no single figure that suits every home. Current guides suggest that renovating a typical three-bedroom property can start from around the mid-£40,000s and rise well into six figures, depending on the condition of the house, the amount of structural or technical work involved, and the standard of finish you choose.

This guide breaks down the main costs, explains where budgets tend to rise, and shows what to consider when planning a refurbishment in Kent, so you can set a more realistic budget before requesting a detailed quote.

Planning a refurbishment in Kent?

If your property needs more than a cosmetic refresh, our house refurbishment service covers full and partial refurbishments, including multi-room work and layout changes. A site visit is the best way to turn national guide prices into a figure based on your actual property.

A useful refurbishment budget is a clear scope, realistic allowances for the expensive rooms, and a contingency for what cannot be seen until work begins.

What drives refurbishment costs in 2026?

For a full house refurbishment in the UK in 2026, the overall cost depends heavily on how much of the property needs replacing, upgrading, or reconfiguring.

The main cost drivers are property size, condition, structural work, specification, labour and location. A home needing plastering, decorating and flooring will sit in a different bracket from one requiring a rewire, heating changes and walls removed.

UK renovation cost guides suggest budgeting roughly £650 to £2,800 per m², with the final figure depending on the condition of the property, the scope of work, and the chosen specification.

A practical price breakdown by room and trade

For a typical three-bedroom home, current 2026 guide prices include:

  • Rewiring: around £4,000 to £8,500.
  • New heating system: around £3,000 to £8,500.
  • New kitchen: around £7,000 to £25,000.
  • New bathroom: around £7,000 on average.
  • Replastering walls: around £10,000 to £15,000.

Looking at a house refurbishment price breakdown by the main rooms and trades makes it much easier to see where your budget is likely to go. Some homes can keep existing systems, while others need several major elements replaced at once.

Kitchens and bathrooms deserve extra attention

A useful UK refurbishment cost guide by room should give kitchens and bathrooms extra attention because both combine fittings, skilled labour, plumbing, and electrical work.

Where these rooms form part of a larger project, our kitchen fitting service and bathroom fitting service cover complete installations.

Why your Kent renovation costs need a local quote

When estimating the cost of renovating a house in Kent, national averages are useful for orientation, but the property itself will determine the final figure. Access, property age and your chosen finish can all affect the final cost.

A useful detail generic calculators often miss is sequencing. If electrics, plumbing, plaster and finishes all need replacing, coordinating them as one programme can help avoid undoing newly finished work. On our refurbishment projects, we assess the property first, agree the plan, provide regular updates and use weekly senior project-manager site visits on larger projects.

How much contingency should you allow?

If you are asking how much a house refurbishment costs in the UK, remember that a sensible budget also needs room for unforeseen work. Checkatrade recommends around 10% to 15% for unexpected costs, such as issues uncovered after floors, walls or old fittings are opened up.

Allow separately for surveys, professional fees, temporary accommodation where needed and approvals. Refurbishments do not automatically require planning permission, but some work can require Building Regulations approval. Government guidance includes examples such as new bathroom installations, replacement boilers, certain electrical work, windows and roof replacement.

Building a budget you can actually use

Separate “must do” work from “would like” upgrades. Deal first with structure and essential services, then allocate the remaining budget to kitchens, bathrooms and finishes. Ask for itemised, like-for-like quotations.

For homeowners comparing house renovation costs in Kent, a property-specific quotation will usually be far more useful than relying on another homeowner’s total spend.

A realistic refurbishment budget starts with the property

The most reliable next step is to define the scope, set priorities and obtain a detailed local assessment.

Frequently Asked Questions

Is it cheaper to refurbish room by room?

Sometimes. Phasing can help cash flow, while doing connected work together may reduce repeated setup and making-good costs.

Do I need planning permission for an internal refurbishment?

Sometimes yes; some structural or technical work may still need Building Regulations approval.

What should a refurbishment quote include?

It should clearly set out scope, labour, materials or allowances, exclusions, programme assumptions and how variations will be handled.
