If you are planning to refurbish a house in Oxford, the biggest risk is not always the price you are given at the start. The real risk is what has not been allowed for. 

A property can look simple during the first viewing, but once walls, floors, ceilings, wiring and pipework are opened up, the true condition of the building becomes much clearer. This is where many refurbishment budgets change. 

So, how much does a full house refurbishment cost in Oxford? 

As a realistic 2026 guide, a full internal house refurbishment in Oxford will often sit around £1,200 to £2,000 per square metre. More complex refurbishments involving structural alterations, RSJ steelwork, new layouts, full rewiring, plumbing upgrades, large-scale home extensions or high-end finishes can rise to £2,000 to £3,500+ per square metre. 

These figures are not a fixed quotation. They are a sensible planning guide. The final cost depends on the property, the drawings, the specification, the structure, the access and the level of finish required. 

Why Full House Refurbishment Costs Vary So Much 

No two refurbishments are the same. 

One homeowner may want new flooring, decorating, a kitchen and two bathrooms. Another may need the whole property stripped back, rewired, replumbed, opened up structurally, insulated, replastered and completely rebuilt internally. 

Both projects are called a house refurbishment, but they are not the same job. 

The cost depends on how far the property is being taken back and how much of the existing building can safely remain. In Oxford, this is especially important because many homes are older, have previous alterations, restricted access, or structural conditions that need careful assessment before work begins. 

As a real example, our full refurbishment and double-storey extension project in Oxford fell within the £250,000 to £500,000 range. Projects of that scale vary depending on specification, scope and the level of contractor involvement. On that project, DKM Builders fully managed and delivered all first-fix elements. Second fix items vary with client preference. On this project we included allowances and managed supply and installation throughout.

Typical Full House Refurbishment Costs in Oxford 

For early budgeting, it helps to think in levels.

A light refurbishment typically costs around £600 to £1,200 per square metre. This usually applies where the existing layout remains, the services are mostly usable, and the work is mainly decoration, flooring, kitchen or bathroom upgrades. 

A full internal refurbishment costs around £1,200 to £2,000 per square metre. This usually includes strip-out, rewiring, plumbing upgrades, plastering, new kitchen, bathrooms, flooring, joinery and decoration. 

A structural refurbishment usually costs around £2,000 to £3,500+ per square metre. This applies where the project includes wall removals, steel beams, new openings, major layout changes, extensions, roof works, or a higher specification finish. 

The more structure, services and specification involved, the more important proper planning becomes.

What Is Usually Included in a Full House Refurbishment? 

A proper full house refurbishment is not just about making the property look better. It is about improving how the house works, how safe it is, how comfortable it feels and how well it will perform long term. 

A full refurbishment can include stripping out old finishes, upgrading electrics, replacing plumbing and heating, installing a new kitchen, fitting new bathrooms, plastering, decorating, flooring, joinery, insulation improvements and general making good throughout. 

If the layout is being changed, the project may also include structural calculations, RSJ installation, load-bearing wall removals, Building Control inspections and coordination with an architect or structural engineer. 

This is where an experienced principal contractor becomes important. The work has to be done in the right order, with the right trades, and with the structure protected throughout. 

Why Oxford Homes Need Careful Refurbishment Planning 

Oxford properties often need more thought than standard modern homes. 

Some houses have older walls, uneven floors, previous extensions, older roof structures, poor insulation or outdated services. Others may be in conservation areas or have access restrictions that affect scaffolding, deliveries and waste removal. 

A refurbishment will potentially also uncover work carried out by previous owners that does not meet current standards. This can include poor wiring, unsupported openings, hidden leaks, weak floors, defective plaster, damp issues or badly installed pipework. 

These problems are not always visible before work starts. That is why a proper refurbishment budget should include sensible allowances and a realistic contingency. 

The Biggest Reason Refurbishment Budgets Increase 

The biggest reason costs increase is usually hidden work.

This can include structural problems, outdated wiring, plumbing that needs replacing, damp, rotten timber, poor previous workmanship, roof defects, uneven floors, or services running through areas that are being altered. 

Another common reason is specification change. A project may start with a basic kitchen or bathroom allowance, but the final client choices may include higher-quality units, stone worktops, premium tiles, underfloor heating, bespoke joinery or upgraded lighting. 

Neither of these is unusual. The key is to identify as much as possible before the project starts and to be clear about what is included in the quotation. 

Structural Alterations and RSJ Steelwork 

Structural work changes the nature of a refurbishment. 

If you are removing walls, forming open-plan spaces, installing RSJs, changing staircases or altering the roof structure, the project needs proper design and control. 

The cost of structural work isn't just the steel beam; it can also include temporary propping, padstones, bearings, making good, fire protection, plastering, electrical alterations, plumbing alterations, and Building Control inspections. 

On a recent full renovation in Abingdon, a load-bearing wall was removed to the structural engineer's design to form an open-plan kitchen, dining and living area. Structural steel beams were installed in accordance with the engineer's calculations, then fire-protected and signed off through Building Control. This sequence - engineer's design, installation, fire protection, inspection - is what separates a compliant structural alteration from a problem discovered at resale.

Kitchen and Bathroom Costs During a Refurbishment 

Kitchens and bathrooms are often two of the most expensive areas in a refurbishment because they involve several trades in a small space. 

A kitchen may require electrical work, plumbing, plastering, flooring, lighting, ventilation, fitting, worktops and decoration. The cost can change significantly depending on the kitchen supplier, appliances, worktops and layout. 

Bathrooms can also vary widely. A simple bathroom replacement is very different from relocating a bathroom, forming a new ensuite, moving drainage, tanking a shower area or installing higher-end tiles and fittings. 

When budgeting for a full refurbishment, it is important to decide the kitchen and bathroom specification as early as possible. If these choices are left vague, the final cost will be harder to control. 

How Long Does a Full House Refurbishment Take? 

A light refurbishment can take several weeks. 

A full internal refurbishment, meanwhile, can take anywhere between two to four months depending on the size, scale, and complexity of the renovations. 

A larger refurbishment involving structural work, extensions, roof works, new services or high-specification finishes can take four to nine months or more.

In practice, our Kidlington refurbishment (kitchen, bathroom, flooring, staircase, rewiring and full internal modernisation, with no structural extension) took approximately four months. Where extensions and structural alterations are involved, the programme extends: our Oxford double-storey extension and full refurbishment ran to six months, and a full refurbishment with rear extension in East Oxford took approximately seven.

The programme depends on the size of the property, how much work is being done, whether the house is occupied, how quickly decisions are made and whether hidden issues are discovered during the build. 

The correct sequence is important. Structural work and first fix services need to happen before plastering, flooring and decorating. If the order is wrong, finished work can be damaged or repeated. 

Should You Move Out During a Full Refurbishment? 

For major refurbishments, it is often better if the property is empty. 

Living in the house during a full refurbishment can slow the work down and make the process more stressful. It also makes dust control, heating, water, temporary electrics, bathrooms and kitchen use more difficult. 

For smaller refurbishments, it may be possible to phase the works. However, if the project includes rewiring, replumbing, structural alterations, plastering and flooring throughout, staying in the property may not be practical. 

This should be discussed before work begins so the programme and site setup are realistic.

Should You Keep a Contingency? 

Yes. A contingency is not a luxury. It is sensible planning. 

For a straightforward refurbishment, a 10% contingency is typically enough, and what we advise for our clients. For older properties, structural refurbishments or homes with unknown previous alterations, 15% to 20% is more realistic. 

A contingency is not money automatically spent. It is a reserve for genuine unknowns, such as hidden defects, rotten timber, poor existing wiring, damp, structural changes or Building Control requirements discovered after opening-up works. 

How to Keep Refurbishment Costs Under Control 

The best way to control costs is to make clear decisions before work starts. 

A detailed scope of works, realistic specification, proper drawings, structural information and clear allowances will reduce confusion later. It is also important to understand what is included, what is excluded and what is provisional. 

The cheapest quote is not always the best quote. A low price that misses important work can become expensive once the project has started. 

A good refurbishment quote should explain the work clearly, identify assumptions, include realistic allowances and make the client aware of risks before construction begins.
