Interior, Exterior, or Both

When calculating overall renovation costs, it is beneficial to distinguish between renovations targeting the interior, the exterior, or both areas of a property.

Interior refurbishment

A complete interior refurbishment usually entails updating floors, walls, and ceilings throughout, as well as renovating bathrooms, the kitchen, plumbing, and electrics. This sort of refurb is more expansive than a mere cosmetic makeover, as it involves deeper structural or systems work.

How Much Does Interior Renovation Cost?

Drawing on data from previous completed jobs, simpler interior renovations may cost around £650 per m² for the smallest scale, whereas larger or more complex ones can reach as high as £2,000 per m². The mean figure is close to £1,100 per m² for most typical projects. These estimates typically include materials, labour, and incidentals, but final costs fluctuate based on each homeowner’s style preferences and any hidden issues.

Exterior renovation

External renovation can incorporate improvements like:

• Drainage solutions
• Extra insulation
• Re-pointing brick walls
• Re-rendering or cladding
• Replacing the roof
• Installing new windows and doors

How Much Does Exterior Renovation Cost?

Costs can vary heavily, but exterior projects often fall in the £400–£700 per m² (wall area) bracket. When materials are modest and structural adjustments minimal, lower-end quotes might land between £250 and £400 per m². If your property demands premium products, complex scaffolding, or meticulous finishing, prices can climb above £700 and even exceed £1,200 per m².

Many houses in Barking and Dagenham have brick façades that can benefit from re-pointing or fresh render, improving both appearance and insulation.

Both interior and exterior

If you intend to tackle both inside and outside simultaneously, anticipate a substantial rise in the project’s overall cost. Combined refurbishments often start near £1,500 per m², with advanced designs or large-scale works reaching £3,500 per m². Renovating in this all-inclusive manner is commonly cheaper than constructing a new-build from scratch, since core elements like foundations and the main frame remain in place. According to BCIS figures, building a new home in the UK sits at about £2,600 per m², inclusive of VAT and every expense.

Complete Home Renovation in Barking and Dagenham 

A full-scale home renovation in Barking and Dagenham offers a unique opportunity to blend contemporary comforts with the area’s distinctive housing stock. Properties here often hail from the mid-20th century, meaning they may require updates that go beyond mere cosmetic fixes—think new electrics or heating systems. 

One of the advantages of renovating in this borough is that, compared to more central parts of London, labour charges can be moderately lower. Local renovation prices here tend to range somewhere between slightly below and roughly average for the capital, making it more affordable than certain pricey inner-London zones.

A standard approach for a large-scale makeover is to begin with thorough surveys or professional assessments, ensuring any hidden damp or structural concerns are identified from the outset. 

Given the Council’s encouragement for improved living conditions, you might also explore potential grants or guidance when upgrading older insulation or inefficient boilers. Remember to check local planning requirements if, for example, you plan to extend a ground-floor layout or convert the loft—though typical internal work usually does not need formal permission.

Great opportunities in Barking and Dagenham

Neighbourhoods in Barking and Dagenham sometimes feature older homes with spacious gardens, allowing room for rear extensions to create larger open-plan kitchens and living areas.

Ultimately, breathing new life into a property here can significantly enhance its value, particularly if you install modern kitchens, bathrooms, and energy-saving features. Whether your priority is longevity, aesthetic appeal, or boosting resale potential, a carefully planned renovation in Barking and Dagenham can deliver considerable returns for both families and investors alike.

What Drives the Cost in a Complete Renovation?

Although general square metre rates offer guidelines, any of a number of factors can influence whether your final bill goes up or down:

1. Size of property
   The total area is a primary driver of cost. Although per-m² pricing exists, working on a larger property might reduce the unit cost somewhat because fixed expenditures (like site setup) spread out across more space.
2. Complexity
   Buildings with complex layouts or numerous bathrooms tend to run higher. For instance, bathrooms often command outsized expense relative to their footprint since they require additional plumbing, tiling, and waterproofing. Some homes in Barking and Dagenham date back decades and often need substantial plumbing or wiring updates during an interior refurbishment.

3. Number of bathrooms
   According to the Federation of Master Builders, a high-quality bathroom refit typically falls between £20,000 and £32,000, making it one of the priciest rooms to renovate. 
4. Structural changes
   Altering load-bearing elements can increase cost, as specialists and planning permissions might be involved. Non-structural tweaks are less expensive but still require care.
5. Materials
   Differences between basic and premium materials can lead to big variations in your bottom line. Many owners find that mid-range choices offer a sweet spot of quality and value.
6. Choice of contractor
   The person or firm you hire can greatly affect your costs. Seek multiple quotes, confirm references, and aim for professionals with credible track records in projects similar to yours. 

In Barking and Dagenham, well-established building companies sometimes specialise in typical local property styles, ensuring a smoother overall experience.

What’s Included in the Contractor’s Quote?

Before you accept any bid, clarify which tasks or supplies the contractor has included. Typically, the quote covers:

• All necessary labour needed for the job
• Project management tasks, if relevant
• Basic materials (timber, plasterboard, adhesives)
• Specialist trades like electricians or plumbers (sometimes itemised as sub-contracts)

By contrast, items considered “finishing materials” may not be in the basic quote. Homeowners often purchase flooring, taps, cabinets, tiles, and bathroom suites themselves, but the builder installs them. This arrangement grants control over style and helps with cost comparisons.

• Kitchen units: While some quotes encompass standard kitchens, high-end or bespoke units typically fall to the homeowner’s own budget.
• Tiles, flooring: Tiles and wooden floors might range from £20 per m² upwards of hundreds per m², depending on your chosen brand or design.
• Bathroom fixtures: Basic suites can be surprisingly cost-effective, but luxury bathtubs and fittings can quickly escalate the bill.

Cost Breakdown for Individual Elements

To illustrate how expenses might be distributed, here is a sample cost breakdown for a 230 m² detached residence undergoing a full interior-exterior refurbishment. Though every project varies, it can help visualise how each piece slots into the total:

Building Regulations for a Complete Home Renovation (UK)

Significant property updates must adhere to Building Regulations to maintain safety and efficiency standards. Always contact your local Building Control office in advance:

When Do You Need Building Regulations Approval?

• Structural modifications: Removing structural walls, inserting beams, or altering major supports.
• Bathrooms and plumbing: Adding a brand-new bathroom or moving drainage lines triggers compliance with drainage regulations.
• Electrical changes: Rewiring or circuit extensions, especially in wet areas, require meeting Part P guidelines.
• Heating installations: Boilers or fireplaces must be fitted by qualified technicians following Part J and Part L rules.
• Windows and doors: Replacements must conform to minimum energy ratings (Part L) and safety glazing (Part K).
• Garage/basement conversions: Converting these spaces to habitable rooms will likely need sign-off to confirm insulation, ventilation, and emergency exits.

Additional Considerations

• Fire safety: Open layouts frequently need fire-rated doors or integrated alarm systems.
• Ventilation: Extract fans in bathrooms and kitchens ensure moisture control.
• Energy efficiency: A major renovation often involves upgrading insulation and glazing to modern standards.
• Soundproofing: If subdividing a property, Part E addresses noise between new dwellings.

Expect either a Full Plans application (with prior checks) or a Building Notice approach if your project is simpler. An official completion certificate will confirm final compliance. Remember to always check with local authorities when in doubt: Barking and Dagenham residents frequently consult the local council’s Building Control to clarify codes when reconfiguring older terraced homes.

Do I Need Planning Permission?

Separate from Building Regulations, planning permission is mainly concerned with your property’s outward appearance and land usage:

• Listed buildings: Alterations tonthe property will likely need Listed Building Consent.
• External modifications: New dormer windows, changed roofing, or re-cladding may require permission, especially in protected neighbourhoods.
• Change of use: Splitting a house into flats or converting to commercial usage typically requires official approval.
• Extensions or loft conversions: While many smaller expansions are covered by Permitted Development, double-check if your plans exceed those limits.

If you have a home in a conservation area of Barking and Dagenham, do verify local planning restrictions before altering your exterior walls or roofline.

How to Find the Right Professionals

The quality of your renovation largely depends on the professionals you select. Unfortunately, the building industry sometimes attracts less-than-reputable workers, but a careful search can locate reliable and experienced companies.

• Credentials and references: Groups such as TrustMark or the Federation of Master Builders keep records of vetted trades.
• Verified leads: Platforms like TrustedBuilders also vet tradespeople, ensuring credit checks, accreditation, and prior job success.
• Project organisation: You might hire a primary contractor to manage specialists or opt to organise separate trades yourself. If you choose the latter, expect heavier involvement to ensure everyone’s schedule aligns.

Local forums within Barking and Dagenham can be great sources of feedback on trades and might speed up your search for proven professionals.
