How Much Does Renovation in Croydon Cost?

Understanding renovation expenses often starts with knowing whether you’re renovating the interior, the exterior, or combining both.

Interior refurbishment

A full interior refurbishment, sometimes labelled a complete interior renovation, generally means swapping out all surfaces (floors, walls, ceilings), modernising bathrooms and the kitchen, reworking plumbing, and updating electrics. This goes deeper than a simple decorative refresh. In Croydon, many post-war terraced or semi-detached houses profit from interior refurbishments that address outdated wiring and bathrooms simultaneously.

Drawing from industry data and completed examples, smaller interior makeovers can cost around £650 per m², whereas more involved or bigger projects could reach £2,000 per m². The usual figure sits near £1,100 per m², encompassing overall project expenses, including materials you might buy independently. Actual totals may shift significantly depending on chosen finishes and conditions on site.

Exterior renovation

An exterior renovation may include:

• Drainage enhancements
• Insulation upgrades
• Brickwork re-pointing
• Applying render or cladding
• Roof maintenance or renewal
• Installing new windows and doors

Prices vary widely based on material choices, property dimensions, how many storeys, local labour rates, and any structural defects. Typically, expect £400–£700 per m² (wall area). A simpler scheme can be £250–£400 per m², while higher-end or more intricate approaches might exceed £700–£1,200+ per m². Note that some older Croydon houses built in the 1930s have brick or pebble-dash exteriors that might need specialised attention or thorough rendering to modern standards

Both interior and exterior

Covering both inside and outside in one project boosts costs substantially. A dual renovation commonly begins at £1,500 per m², potentially climbing to £3,500 per m² for more complex scenarios. Nevertheless, it’s generally less expensive than an entirely new build, since existing foundations and structural elements remain. Industry findings indicate that a new property in the UK averages about £2,600 per m² with VAT, which serves as a reference when weighing refurbishment costs.

Complete Home Renovation in Croydon

Renovating a property in Croydon can offer an intriguing blend of suburban living and relatively lower London property prices, often making refurbishment projects more accessible than in pricier boroughs. This area features a diverse mix of housing styles—ranging from 1920s-1930s semis around Addiscombe or South Croydon, to newer apartments near East Croydon station. Upgrading older interiors is a frequent goal, because many local homes still have original plumbing or wiring that merits modernisation. It’s not unusual for homeowners to add rear extensions, given the decent garden sizes in many suburbs, boosting kitchen-diner space.

When planning a refurbishment here, labour costs can be somewhat lower than central London, though still above many national averages. That said, Croydon’s ongoing regeneration efforts and good transport links can help raise property values, meaning renovations often see a solid return. If you’re tackling the exterior, be aware that some neighbourhoods have distinctive brick or tile-hung façades that might need specific materials or matching colours. Certain streets in Croydon lie in conservation zones—like parts of the Old Town—where changing windows or adding roof dormers may require permission from the council.

Most owners set aside a portion of the budget for energy-efficiency improvements, such as adding loft or wall insulation. Over time, that can cut heating bills and make your home more comfortable. Furthermore, if you own a 1930s semi, you might look into installing better drainage or upgrading older roof structures to safeguard against damp or leaks. Overall, Croydon offers a practical environment for those wanting a complete home update without the extreme costs of central boroughs, though thorough planning and skilled trades are still essential for a smooth result.

What Drives the Cost in a Complete Renovation?

Although the per-m² figures above are a valuable starting point, there are many variables that may push your final bill higher or lower.

Size
Prices are often quoted per square metre as naturally the total floor area strongly affects the final figure.

Complexity
Buildings with numerous bathrooms or intricate details will drive up expenses more than simpler layouts. Architectural quirks also tend to boost labour demands.

Number of bathrooms
Bathrooms, or wet rooms, are consistently among the priciest areas. As noted by the Federation of Master Builders, a top-to-bottom bathroom refurbishment typically ranges £20,000–£32,000, depending on finish. Kitchens, similarly, cost more than standard living areas.

Structural modifications
If the contractor must carry out work on load-bearing elements, the costs go up, compared to just relocating non-structural walls. Such alterations often need engineering input and potentially planning permission.

Materials
Your selection of fixtures and fittings shapes overall spend. While standard building items may not allow huge savings, premium bathroom or kitchen gear can raise costs sharply.

Choice of contractor
Finally, who performs the work matters greatly. Investigate multiple quotes, references, and accreditations. Accredited trades mean better reliability, balanced pricing, and quality assurance. Groups like the Federation of Master Builders or TrustMark provide guidance, and TrustedBuilders also connects clients with reputable contractors.

What's Included in the Contractor's Quote?

Defining what’s contained in a builder’s quote early on helps avoid later confusion. It typically includes every element of the agreed renovation, involving all trades and standard materials. However, “finishing materials” may be separate.

These finishing materials can include the kitchen, bathroom suites, taps, WC units, floors, and tiles. As discussed, the range in pricing for these elements can be large, reflecting the property owner’s tastes. A basic kitchen might cost £5,000, whereas a high-end, custom design can be tens of thousands. Kitchen fitting normally sits outside the contractor’s main bid, often costing £1,000–£3,000 extra.

Tiles and flooring also fall under finishing materials. If you follow promotions or sales, you can locate major bargains. Costs can start at roughly £20 per m² and climb up considerably for premium lines.

Bathrooms are likewise available in countless configurations. Contractors frequently have arrangement deals with particular suppliers, yet it’s wise to look around. A small bathroom can be done for about £1,000, though many owners pay more for better results. Installation of these fixtures is generally wrapped into your builder’s labour.

Cost Breakdown for Individual Elements

We’ve detailed how per-square-metre costs guide the broader refurbishment price. Below is an example from a 230 m² detached house that underwent a complete inside-outside renovation. Actual figures vary widely, but it’s a helpful reference:

Price (contractor, labour + materials):

• Windows (20 units + delivery): £27,000
• Forming new external window opening: £3,200
• External cladding + insulation replacement: £33,000
• New roof: £21,500
• Drainage: £12,800
• Bathroom (excl. tiles/fixtures, incl. plumber): £19,000
• WC 1 (plumber included): £3,600
• WC 2 (plumber included): £3,600
• Utility room (plumber): £10,800
• New plumbing: £18,400
• External + patio doors: £4,800

  Total (Contractor): £300,800

Client’s separate purchases:

• Tiles (bathroom, WC, utility, hallway): £4,800
• Bathroom fixtures (1 bath + 2 WCs): £6,400
• Kitchen: £24,000
• Additional flooring: £10,000
  Subtotal: £45,200

Grand total: £346,000

That roughly translates to £1,500 per square metre, slightly beneath the norm for this size and type of refurbishment.

Building Regulations for a Complete Home Renovation (UK)

A major renovation must comply with Building Regulations, to ensure it’s safe, efficient, and meets legal mandates. It’s best to consult your local Building Control office well before starting.

When Do You Need Building Regulations Approval?

• Structural modifications – Removing or altering load-bearing walls, chimney breasts, or adding new door/window openings. Part A pertains to structure, so a structural engineer’s design is typically requested.
• Bathrooms + plumbing – Adding a bathroom or moving plumbing calls for drainage (Part H) and ventilation (Part F) compliance.
• Electrical work – Rewiring or adding circuits, especially in wet areas, must meet Part P. A registered electrician or Building Control check is needed.
• Heating – New or replacement boilers, radiators, and fireplaces must align with Parts J (combustion) and L (energy efficiency). Gas installations need Gas Safe engineers.
• Windows & doors – Replacements must meet thermal performance (Part L) and safety glazing (Part K). FENSA or CERTASS registration streamlines compliance.
• Garage/basement conversions – Converting these areas to liveable rooms always needs sign-off for insulation, fire safety, damp-proofing, ventilation, and more.

Additional Considerations

• Fire Safety (Part B) – If you create open-plan layouts, extra fire doors or alarms might be needed to keep escape routes safe.
• Ventilation (Part F) – Kitchens, bathrooms, and utility spaces require adequate extraction.
• Insulation & Energy (Part L) – Large-scale refurbishments generally mean upgrading insulation (walls, roofs, windows) to modern levels.
• Soundproofing (Part E) – Splitting a property into flats or adapting garages/lofts for living can prompt acoustic insulation standards.

You can either submit detailed plans beforehand (Full Plans application) or use a Building Notice for simpler tasks. A completion certificate follows successful inspections.

Do I Need Planning Permission?

Planning permission differs from Building Regulations. Most internal renovations do not need planning consent, unless:

• Listed buildings – Any alterations to a listed structure’s character (internal or external) demand Listed Building Consent.
• External modifications – Creating new openings, re-roofing, or changing exterior materials might call for permission, particularly in conservation areas.
• Change of use – Converting a property to flats or shifting from residential to commercial.
• Extensions/loft conversions – While interior work typically avoids permission, outward expansions or raising the roof typically need council approval.

In Croydon, areas like Waddon or Addiscombe aren’t usually in strict conservation zones, but certain older streets require checks, especially for external changes.

For general interior layout rearrangements, bathroom or kitchen updates, or redecorating, permission isn’t required unless local designations apply. Always confirm with your planning authority if uncertain.

How to Find the Right Professionals in Croydon

Choosing the right trades determines whether your refurbishment proceeds smoothly. While some dubious operators are out there, plenty of skilled construction firms handle complete renovations successfully. In the UK, TrustMark and the Federation of Master Builders are good starting points for vetted contractors, while TrustedBuilders reviews credit histories, confirms accreditations, and checks references to connect you with an ideal match.

Depending on how much project management you can do, you might hire individual trades or go with a single main contractor. A principal contractor typically oversees subcontractors, guaranteeing compliance with guidelines and quality standards. Alternatively, if you split the job among different trades, you’ll be more involved day to day.
