House Renovation in Oxford

A renovation is the one job where the survey matters more than the mood board. Strip back an Oxford house — a Victorian terrace off the Cowley Road, a thirties semi in Headington, a stone cottage in one of the villages — and what sits behind the plaster sets the budget long before anyone chooses a worktop. Lynch Brother Homes runs whole-house renovation and refurbishment throughout the city as principal contractor — a single business holding the programme from first strip-out through to handover, and a single business accountable when the wiring turns out older than the survey implied.

We are a family construction business employing over fifty trades, working out of Bradley Farm at Cumnor, west of the city. Our two directors, Henry Lynch and John Lynch, both trained as carpenters, and one of them attends every live site. Building runs three generations deep here: their grandfather worked Oxford sites including what is now the Clarendon Centre during the 1950s, and the family has been building under the Lynch name since 1984. Refurbishment is the work this business grew out of, and it remains a substantial part of the diary — alongside house extensions, loft conversions and new builds.

Two Oxford refurbishments, in detail

80 Lime Walk in Headington is the clearest example of what a full refurbishment involves. Appointed as main contractor, we took the property back to its shell and rebuilt it around a better plan. Steels went in to throw the ground floor open into one continuous cooking, eating and sitting space. The bathroom shifted upstairs, freeing area below, and the bedroom at the back gained size. Out of sight: every circuit renewed, fresh pipework, a new heating system, and underfloor warmth laid beneath the replacement kitchen. Externally it gained a silicone render in K Rend, a replacement roof, new glazing, a garden redesigned from scratch, and a detached structure at the rear giving them both a garage and a home office. It is a two-bedroom terrace that now works like a considerably larger house.

The Nook at Islip shows the other kind of renovation we are asked for: an eighteenth-century cottage inside a conservation area, reimagined with Nine Ten Architects into a light-filled family home without losing what made it worth buying. Structural walls were removed and steel let carefully into the old stonework. At its centre sits a deVOL kitchen made to measure, surrounded by clay plaster and period-appropriate finishes applied by J & H Lynch, the plastering arm of the Lynch Group, with Noble Painting & Decorating responsible for every decorated surface. Period fabric, modern layout, and a conservation officer satisfied at the end of it.

What a house renovation costs in Oxford in 2026

Renovation is the hardest building work to price from a distance, which is why so many guides land on a single meaningless average. The honest way to budget is to decide how deep you are going, then apply a rate to your floor area. The bands below are aggregated from current 2026 UK cost data and widened at both ends, because the truthful answer is a range rather than a number. They cover labour, materials and VAT, and exclude professional fees and any extension.

Those rates sit below what the same floor area costs as new build, and below the £2,000 to £3,200 a square metre an extension costs, for the straightforward reason that the shell, the roof and the foundations already exist. If you are adding space as well as reworking what you have, price the two separately and add them together — our 2026 extension cost guide covers that side.

Why we will not put a number on structural work. Once walls start moving, banded pricing stops being useful. Two houses of identical size can differ by six figures depending on how many of the walls are load-bearing, what the ground and foundations turn out to be, whether the roof structure has to change, and how bespoke the joinery becomes. Anyone quoting you a confident per-square-metre rate for that sight unseen is guessing. It is the single best reason to get us round the house early: an hour on site tells you more than any cost guide, and it costs you nothing.

Renovations are also priced element by element once the scope is clear. These are the ranges the individual pieces fall into, again aggregated from current market data:

Two things belong in every renovation budget and are left out of most: professional fees, typically five to twelve per cent of the build cost once an architect, structural engineer and building control are involved, and a contingency of ten to twenty per cent. On a house built before 1940, take the upper end of that contingency. Every quotation goes out written and broken down line by line, built from a survey and never from a rate card — and we would sooner hand you an unwelcome figure on day one than at week six.

The types of renovation we take on

Most Oxford renovations are an assembly of smaller projects running under one programme. These are the pieces, each with a page of its own if you want the detail:

Whole-house refurbishment

The house stripped back and rebuilt around how you actually want to live in it. Rewire, replumb, heating, plastering, joinery, kitchen, bathrooms and decoration, with structural work where the layout demands it. This is the work at 80 Lime Walk, and it is the most common brief we are given on a recently purchased property.

Period and conservation-area renovation

Older Oxford housing stock needs builders who have handled lime, stone and lath before. Repointing, structural openings threaded into existing masonry, breathable finishes and matched materials — the approach we took at The Nook. With eighteen conservation areas in the city and more across the county villages, this is routine work for us rather than a speciality we occasionally attempt.

Kitchens and bathrooms

The two rooms that absorb the largest share of any renovation budget and change daily life the most. We fit both as part of wider projects and as standalone jobs — see new kitchens and new bathrooms.

Adding space: lofts, garages and extensions

Where a renovation needs more floor area rather than a better arrangement of it, the options are a loft conversion, a garage conversion or an extension. Folding them into a refurbishment while the house is already open is almost always cheaper than returning to do them separately.

Services, fabric and finishes

The parts nobody photographs: electrical work, plumbing and heating, damp treatment, flooring, exterior rendering and painting and decorating. These decide whether the house works in ten years, not just whether it photographs well in month one.

Planning permission, conservation areas and building regulations

Most internal renovation needs no planning application. Reconfiguring rooms, replacing kitchens and bathrooms, rewiring and redecorating are yours to do. The picture changes as soon as the work becomes visible from outside or the building is protected.

There are eighteen conservation areas inside the city, Iffley and Old Headington included, and within them consent is needed for external alterations, window replacement, cladding and most demolition, with materials expected to match what already exists. Listed buildings go further still: internal changes require listed building consent as well, which catches people out, because shifting a wall inside a listed cottage is a consent matter rather than a free choice. Article 4 directions strip permitted development rights from certain streets altogether. Beyond the ring road, four separate district councils each take their own line, and planning permission across Oxfordshire is ground we cover most weeks.

Building regulations, by contrast, apply to almost everything structural or service-related regardless of planning: new openings, rewires, heating systems, insulation, drainage and fire safety. We run building control from the first application through the inspection stages to the completion certificate — the paperwork a buyer’s conveyancer will want to see years down the line.

How a whole-house renovation actually runs

Survey and feasibility. Before design fees are committed we look at the fabric, the services, the damp position and the planning constraints, and tell you what the house will take. On pre-1940 stock we would rather you paid for a structural survey than discovered the problem at strip-out. Design and consents. We work alongside whichever architect you have engaged, or point you towards one, and get applications in with drawings and structural calculations already finished. Strip-out and structure. The messy half: clearance, structural openings, steels, roof and external fabric. First fix and services. Wiring, plumbing, heating and insulation while the walls are open. Second fix and finishes. Plaster, joinery, kitchen, bathrooms, flooring, decoration. Snagging and handover. Building control sign-off, certificates and a snagging list we work through rather than argue about.

Most whole-house refurbishments run three to eight months on site depending on depth, with design and consents ahead of that. Whether you can live in the house through it depends on the depth: a light refurbishment usually yes, a full rewire and replaster realistically no, because you lose power, water and every ceiling at some point. We will tell you honestly which one you are facing at the survey, because budgeting for six months of rent is a very different project from budgeting for none.

The trades belong to us, not to a subcontractor’s diary

Renovation goes wrong at the joins. The plasterer waiting on the electrician, the decorator arriving before the render has cured, four trades each blaming the one before. We stripped most of that risk out by keeping the work inside the group: plastering, screed and render sit with J & H Lynch, decoration with Noble Painting & Decorating, and electrics, plumbing and heating with our own directly employed people. One programme, one main contractor, one number to ring.

We hold TrustMark registration and Federation of Master Builders membership, took a project nomination at the 2025 FMB Master Builder Awards, and received SME recognition at the 2025 Constructing Excellence SECBE Awards. Most of our work still arrives by personal recommendation, which is the only reputation measure that has ever mattered in this trade.

Where we renovate

We refurbish houses across Oxford — Headington, Summertown, Jericho, Cowley, Iffley and the rest — and throughout the county from our base at Cumnor. Recent work sits in Kennington, Kidlington, Abingdon, Eynsham, Wheatley, Faringdon, Didcot and Henley-on-Thames. The whole county picture sits on our builders in Oxfordshire page.

Renovation questions we get asked most

How much does it cost to completely refurbish a house in Oxford?

A full refurbishment — rewire, replumb, new heating, kitchen, bathrooms, plastering and decoration throughout — runs roughly £605 to £1,985 per square metre, so around £54,450 to £178,650 on a 90m² three-bedroom house. A lighter refresh sits at £185 to £775 per square metre. Structural work, where walls move, is too variable to band honestly and needs a site visit. Professional fees of five to twelve per cent and a contingency of ten to twenty per cent sit on top.

Is £40,000 enough to renovate a house in Oxford?

For a light refurbishment it can be — redecoration, flooring, doors, light fittings and making good falls between £185 and £775 per square metre, so £40,000 covers a good deal of a typical house. For a full refurbishment of a three-bedroom house it is tight, and £50,000 not much less so: once a rewire, a replumb and replastering are involved the range starts around £54,450 and climbs. The useful question is not what a budget buys in general, but which depth of renovation it buys on your house — which is exactly what a survey answers.

What is a realistic renovation budget for an Oxford property?

Take your habitable floor area, apply the rate for the depth of work you want, then add professional fees of five to twelve per cent and a contingency of ten to twenty per cent. On a house built before 1940 use the top of the contingency range: pre-war Oxford stock reliably produces something unexpected once the plaster is off.

What is the most expensive part of a house renovation?

The kitchen usually takes the largest single share, typically £6,515 to £27,560 supplied and fitted. But the costs that damage budgets are the invisible ones — rewiring, replumbing, replastering and structural work — because they are easy to underestimate and impossible to skip. Money spent on fabric and services is never money wasted; money spent on finishes before the fabric is sound usually is.

Do I need planning permission to renovate a house in Oxford?

Usually not for internal work. Reconfiguring rooms, rewiring, swapping kitchens and bathrooms and redecorating are all application-free. Permission becomes necessary for most external alterations inside Oxford’s eighteen conservation areas, for anything on a listed building including internal changes, and on streets covered by an Article 4 direction. We confirm which applies to your property before quoting.

Is it possible to stay living there during the work?

Through a light refurbishment, usually. Through a full one, realistically not: a rewire and replaster removes power, water and ceilings across the whole house at various points. We will tell you which category your project falls into at the survey, so that rent or family arrangements go into the budget from the start rather than appearing halfway through.

How long does a full house renovation take?

Three to eight months on site for most whole-house projects, set by depth rather than size alone. Design, consents and regulatory approval all happen beforehand, so first conversation to finished house is typically six to fourteen months. Conservation-area and listed properties sit at the longer end because consent timescales are outside anyone’s control.
