Best Quoting Apps for UK Builders (2026)

Why Builders Need Quoting Software in 2026

Most builders still quote jobs using a combination of spreadsheets, Word documents, text messages, and mental arithmetic. It works — until it doesn't. You forget to include something, you underquote because you rushed it after a long day, or you lose track of which quotes are still outstanding.

Quoting software solves these problems, but the market is confusing. Some tools are designed for large commercial contractors. Others are glorified template generators. And some are genuinely useful for the kind of small-to-medium builder who's quoting extensions, refurbs, and new builds week in, week out.

Here's an honest look at what's available in 2026.

What to Look For

Before comparing specific tools, here's what actually matters for a working builder:

Speed — Can you create a quote in minutes, not hours? If the software takes longer than your current method, you won't use it.

Mobile-friendly — You're on site all day. If the tool only works properly on a desktop, it's useless for most builders.

UK-specific — VAT calculations, CIS deductions, UK material prices, and payment terms that match how UK construction actually works. American software rarely handles this well.

Professional output — The quote your customer receives needs to look polished. A branded PDF or shareable link that makes you look like you know what you're doing.

Invoicing integration — Ideally, you want to turn accepted quotes into invoices without retyping everything. Bonus points for handling stage payments and retention.

Price — You're running a small business. £500/year for estimating software is a tough sell when you could be spending that on materials.

The Options

BuildScope

Price: Free tier available. Pro at £29/month or £279/year. 14-day free trial.

Best for: UK builders and tradespeople who want AI-powered quoting with invoicing built in.

BuildScope is purpose-built for UK builders. The standout feature is AI quoting — you describe the job in plain English (or speak it using voice-to-text) and the system generates a full itemised quote with materials, labour, overheads, and profit margin. It uses trade-specific labour rates and UK regional price multipliers, so the numbers are grounded in reality rather than guesswork.

Quotes are shared via unique links — your customer can view, accept, or decline online, and you get notified of status changes. Accepted quotes convert to invoices with CIS deductions (20% or 30%), VAT, retention percentages, and stage payments all handled automatically.

The trade-off is that BuildScope is newer to market than some competitors, so it doesn't yet have features like takeoff from drawings or supplier integration. But for the core workflow of quoting jobs and invoicing — it's fast, simple, and built specifically for how UK builders work.

EstimatorXpress (HBXL)

Price: From £899+VAT (perpetual licence) or subscription options. Annual support renewal required.

Best for: Builders doing extensions and new builds who want detailed, template-based estimating.

EstimatorXpress is one of the most established tools in the UK market. It comes with hundreds of pre-loaded templates for renovations, extensions, and new builds, complete with materials, labour, plant, and wastage data. You input your project dimensions and spec, and it calculates quantities and costs.

The depth of detail is impressive — it generates materials schedules, build programmes, cash flow forecasts, and professional quote packs. It's genuinely powerful for detailed estimating.

The downsides: the price point is steep for a sole trader, the interface feels dated compared to modern web apps, and there's a significant learning curve. It's overkill if you just need to knock out quick quotes for smaller jobs.

PriceBuilder

Price: Subscription-based, affordable. Cancel anytime.

Best for: Builders who prefer a hands-on, manual approach to pricing.

PriceBuilder takes a different approach — rather than generating estimates automatically, it provides a structured framework for you to input your own quantities and prices across categories like foundations, walls, roofing, and so on. It has preprogrammed pricing algorithms and a mobile-friendly interface.

The interface is clean and modern — arguably the best-looking tool in this space. The downside is that it requires a lot of manual data entry. For each job, you're filling in fields across 20+ categories. If you're pricing a big job you're confident about, that's fine. But if you're doing quick quotes for smaller works, it can feel like overkill.

Buildxact

Price: Entry and Pro subscription tiers.

Best for: Builders who want takeoff from drawings plus estimating.

Buildxact combines digital takeoff (measuring from PDF plans) with estimating and quoting. You upload drawings, measure quantities directly on screen, and the system prices them using your rate libraries or supplier pricing.

It's a solid all-in-one for builders who regularly price from plans. The supplier integration is a nice touch — you can get live material pricing and order directly. It also does invoicing and scheduling.

The downside for UK builders is that Buildxact originated in Australia, and while it has a UK version, some of the workflows and terminology feel slightly off for the UK market.

RapidQuote

Price: Various tiers. Demo available.

Best for: Builders and contractors focused on takeoff speed.

RapidQuote specialises in speed — particularly for quantity takeoffs from drawings. Users consistently report cutting takeoff time by 80% or more. You open your plans in the software, measure areas, lengths, and quantities, and it generates material schedules with costs.

It's less of a quoting tool and more of an estimating engine. You still need to turn the output into a customer-facing quote. Best suited for builders who regularly price from detailed drawings rather than doing quick site-visit quotes.

Free Templates (Checkatrade, FMB, Xero)

Price: Free

Best for: Builders just starting out or doing very occasional quotes.

Checkatrade, the Federation of Master Builders, and Xero all offer free downloadable quote templates. These are perfectly adequate Word or PDF documents with the basic structure — your details, customer details, line items, totals, and terms.

The limitation is obvious: no automation, no tracking, no CIS handling, and no way to know if your customer has even opened the quote. Fine for one or two quotes a week; painful if you're quoting regularly.

Quick Comparison

Which One Should You Choose?

It depends on how you work:

If you price from detailed drawings and need quantity takeoffs, look at EstimatorXpress or Buildxact. These are proper estimating tools designed for that workflow.

If you want fast, simple quoting with invoicing — especially for site-visit quotes, smaller jobs, and the typical UK builder workflow — BuildScope is built exactly for this. The AI quoting saves real time, and having CIS, VAT, and retention baked into the invoicing is a genuine advantage.

If you're just starting out and only quote occasionally, a free template will do. But you'll outgrow it quickly once you're doing more than a few quotes a month.

If budget is tight, BuildScope's free tier lets you test it properly, and the Pro tier at £29/month is significantly cheaper than most alternatives.
