How Much Do Builders Cost in Brighton? | Brighton Builders

Brighton is one of the most expensive places in the South East to carry out building work — outside London itself and the immediate commuter belt, it sits at or near the top of the regional cost table. That is not a reason to avoid building work, but it is a reason to go into any project with a clear sense of what realistic costs look like in this specific market rather than relying on national averages that are often considerably lower than what local builders actually charge.

The city’s housing stock is one of the most varied and characterful in the country. The Georgian and Regency terraces of Kemp Town, the clifftop squares of Hove, the Victorian bay-fronted semis of Preston Park and Fiveways, the inter-war houses of Patcham and Woodingdean — each era and area presents different building challenges, different planning considerations, and in many cases different costs. A builder working on a Regency terrace in Brunswick Town is doing a materially different job to one extending a 1960s semi in Coldean, and the price reflects that.

This post breaks down what builders cost in Brighton across the main types of building work, explains what drives prices up or down in this market, and gives you a realistic framework for approaching quotes.

Day Rates — What Brighton Builders Charge

Before looking at project costs, it is useful to understand what builders charge per day in Brighton, since day rates underpin the labour element of any quote.

For Brighton and the wider East Sussex area, current day rates from experienced local tradespeople typically run:

• General builder / site labourer: £220–£300 per day
• Bricklayer: £250–£350 per day
• Carpenter / joiner: £240–£340 per day
• Plasterer: £250–£350 per day
• Electrician: £280–£380 per day
• Plumber: £280–£380 per day

These are day rates for experienced, properly insured tradespeople working in the Brighton market. Rates at the lower end reflect sole traders with lower overheads. Rates at the higher end reflect established contractors with full insurance, consistent teams and project management capability.

Brighton rates are meaningfully higher than the national average and higher than comparable work in towns further north or inland. The cost of living, high demand from a buoyant property market, and the premium that skilled tradespeople can command in a city where good builders are consistently busy all contribute to this. When comparing quotes from Brighton builders, a significantly lower day rate than the above should prompt questions rather than relief.

House Extensions

A house extension is the most common major building project across Brighton’s residential streets — and one where the cost variation is wide.

• Single storey rear extension (up to 20 sqm): £40,000–£70,000
• Single storey rear extension (20–35 sqm): £65,000–£95,000
• Double storey extension: £80,000–£140,000+
• Side return extension: £45,000–£75,000
• Wrap-around extension: £75,000–£130,000+

These are finished, installed prices including structural work, roofing, glazing, internal fit-out and building regulations sign-off. They do not include kitchen or bathroom fitting, specialist flooring or bespoke joinery — those are additional.

Brighton’s prices sit firmly at the higher end of the South East range. Several factors drive this. The city’s density means restricted site access is common — skips, scaffolding and material deliveries in narrow terraced streets take longer and cost more to manage than on a suburban plot with a driveway. The prevalence of older properties with solid brick walls, original foundations and non-standard construction adds complexity and time to structural work. And the planning environment — particularly in and around the city’s numerous conservation areas covering the Regency and Victorian heritage — can add design constraints and pre-application advice requirements that add both time and professional fees to the project.

Loft Conversions

Brighton’s bay-fronted Victorian semis and Edwardian terraces are some of the most loft-conversion-friendly properties in the South East — many have the roof pitch and internal volume to support a conversion without major alteration to the external roofline.

• Velux or rooflight conversion: £30,000–£48,000
• Rear dormer conversion: £42,000–£68,000
• Hip to gable conversion: £55,000–£80,000
• Mansard conversion: £65,000–£100,000+

Brighton’s loft conversion costs are higher than the national average for the same reasons as extensions — day rates, restricted access in terraced streets, and the complexity of working on older properties. The mansard conversion figure in particular reflects both the structural involvement and the planning scrutiny that this type of conversion attracts in a city with significant conservation area coverage.

Party wall agreements are relevant to the majority of Brighton’s loft conversions given the prevalence of terraced and semi-detached properties — budget for this as part of the overall project cost rather than as a surprise.

Home Renovations

Full or partial home renovations in Brighton span an enormous range depending on scope and specification.

• Single room renovation (kitchen or bathroom): £8,000–£25,000
• Partial renovation (2-3 rooms, updated services): £25,000–£60,000
• Full whole-house renovation: £60,000–£200,000+

The upper end of the whole-house renovation range applies to larger properties — the substantial Edwardian and Victorian villas of Hove and Kemp Town that are bought as renovation projects and brought back to a high standard. These projects involve structural work, full rewires, replumbing, new heating systems, period feature restoration and high-specification fit-out, and the costs reflect that.

For a more typical renovation — a three-bedroom Victorian terrace in Preston Park being modernised with a new kitchen, bathroom, partial rewire and updated heating — a realistic budget in Brighton is £45,000–£80,000 depending on specification. This is materially higher than equivalent work in most other parts of the country.

What Affects Building Costs in Brighton?

Conservation Areas and Planning

Brighton and Hove has an unusually high number of conservation areas relative to its size — covering much of the Regency and Victorian heritage across the city centre, Hove seafront, and substantial residential areas including Preston Park, Seven Dials and parts of Kemp Town. Works within conservation areas are subject to tighter planning controls, material restrictions and in some cases require full planning applications for work that would be permitted development elsewhere.

This does not make building work impossible — it makes it more carefully considered and in some cases more expensive, particularly where specialist materials or design input are required to meet planning requirements.

Property Age and Construction

The age of Brighton’s housing stock is both its appeal and its main source of building complexity. Original lime mortar, solid brick walls, timber floors with irregular spans, non-standard foundation depths and the accumulated modifications of 150 years of occupancy all add variables that a builder on a modern property simply does not encounter. Opening up walls, underpinning, discovering previous repairs that need undoing — these are the realities of working on older Brighton properties, and they are reflected in both the time and cost of projects.

Site Access

Restricted access is a consistent feature of building work across Brighton’s terraced streets. A skip that can be positioned on a driveway in Patcham costs significantly less in time and logistics than one that needs traffic management in a narrow street in Hanover or North Laine. Scaffolding on a terraced property in a conservation area may require licence applications and neighbour agreements. Material deliveries to sites where there is no off-street storage need careful scheduling. All of this adds to the cost of building work in the city compared with more accessible suburban locations.

Specification

The specification of materials, finishes and fittings has the largest effect on project cost after labour. A kitchen extension finished with standard units, laminate worktops and ceramic tiles costs less than the same space fitted with bespoke cabinetry, quartz worktops and large-format porcelain. The structural and labour costs are identical — the specification determines where the overall figure lands within the range.

Being clear about specification before requesting quotes — and making sure all quotes are covering the same specification — is the most effective way to compare prices meaningfully.

Getting Quotes in Brighton

Three quotes is the standard recommendation and it holds in Brighton as anywhere else. The process of getting quotes tells you as much as the prices themselves — a builder who arrives on time, measures up properly and provides a clearly itemised written quote is demonstrating the professionalism you want on your project.

Be cautious of quotes that are significantly below the ranges above. In a market where experienced Brighton builders are consistently busy, an unusually low price is more likely to reflect underpricing, corner-cutting or a misunderstanding of the project scope than a genuine bargain. The cost of remedying poor building work invariably exceeds the saving on the original quote.
