Cost & estimates
What a renovation costs, by region and room.
Home renovation cost calculator UK
Estimate what a renovation, extension, loft conversion, kitchen or bathroom is likely to cost in the UK. Pick the project type, set the floor area in square metres, choose your specification and your region, and see an estimated cost range with the cost per square metre and a directional split of labour, materials and prelims. A directional model, not a quote: UK build costs swing hard with spec, structural work and access, so the tool always shows a range, never a single number.
Kitchen & Bathroom Fitting Cost Estimator (UK)
Estimate what a new kitchen or bathroom fit costs in the UK, broken down into labour, materials, waste and the range you should expect. Pick the room, set the size, choose a finish level, decide between supply and fit or labour only, and select your region, then watch the estimated cost update in real time. A directional model built on UK market prices for 2026, not an inflated sales number: the real price always depends on complexity and the fitter you pick.
Pricing & profit
Your day rate, true margin and job profit.
CAC and payback period calculator
Work out what it costs to win a new customer (CAC) and how many jobs and how many months it takes to recover that investment. Adjust your monthly marketing spend, the new customers it generates, the average first job value, your gross margin and repeat jobs per year, and you'll see your CAC, the gross profit on the first job, payback in jobs and in months, and the annual gross profit per customer. Transparent, directional model: a healthy business recovers CAC within the first 1-2 jobs.
Capacity and Staffing Calculator
Check whether your trades business has the capacity to meet the demand coming in and how many tradespeople you actually need so you stop turning work away or carrying idle crew. Adjust the jobs coming in per week, the average hours per job, the people on payroll, the billable hours per person and the average job value, and you will see your utilisation rate, your real capacity in jobs, your headroom or shortfall, the tradespeople needed and the revenue you leave on the table each week when demand outruns capacity. A transparent model, with no promises.
Customer Lifetime Value (LTV) Calculator
Work out what a home-services customer is really worth across the whole relationship, not just the first job. Adjust your average job value, jobs per year, retention years, gross margin and referrals, and see the margin-based LTV, the revenue LTV, the value including referrals, and the most you can sustainably pay to win a customer under the classic 3:1 LTV:CAC rule. A transparent, directional model grounded in the retention research of Bain & Company and Harvard Business Review.
Day rate calculator for tradespeople
Work out the day rate you should charge as a UK tradesperson to hit your take-home after overhead, downtime and tax. Adjust the take-home you want, your annual overhead, your billable days per week, the weeks you work, an allowance for Class 4 NIC and income tax, and your billable hours per day, and see your recommended day rate, hourly rate and the pre-tax turnover you need. The classic mistake is pricing on days worked, not billable days, and forgetting the overhead and the taxman.
Hourly rate calculator for tradespeople
Work out the hourly rate you need to charge to hit your income goal while covering every cost. Adjust the take-home income you want, your annual overhead, the hours you actually invoice each week, the weeks you work and your extra margin, and see your break-even rate and your final hourly rate. No magic formulas: the classic mistake is pricing on hours worked, not billable hours, and forgetting overhead entirely.
Job Profit Margin Calculator
Work out what a building or trade job actually makes you, not what the quote says. Enter the price you have quoted the client ex-VAT, your materials and labour cost, the hours the job will take and a contingency on cost, and instantly see the net profit, the real net margin, the markup on cost and the profit per hour. The tool makes the leak obvious: confusing margin with markup and skipping contingency is how profitable-looking jobs end up barely breaking even.
Maintenance plan revenue calculator
Calculate how much predictable recurring revenue your trades business can generate with an annual maintenance or service plan. Adjust your active customers, the share who join the plan, the yearly price, how long members stay, and your current one-off revenue, and you will see the ARR, the MRR, the recurring value over the whole retention period, and how much of your revenue becomes predictable. A transparent, directional model with no inflated numbers.
Quote Margin and Markup Calculator
Price a trade job without falling for the most common pricing mistake: confusing margin with markup. Enter the job cost (materials plus labour), choose whether to price by margin or by markup, adjust the percentage, and instantly see the price to charge, your profit, your real margin and your real markup. The tool makes it obvious why a 30% markup leaves only about a 23% margin, a leak that erodes profit quote after quote.
Retention and churn calculator
Calculate how much money your home-service business loses every year to customer churn, and how much you would gain by cutting that leak by a few points. Adjust your active customers, your annual churn rate, the average revenue per customer, your gross margin, and the points of churn you aim to cut, and you will see the revenue lost per year, the average customer lifespan, the extra customers you keep, and the extra profit you generate. A transparent, directional model.
Marketing & leads
ROI on ads, calls, reviews and leads.
Break-Even ROAS Calculator for Tradespeople
Calculate the minimum ROAS you need before your ads start losing money, based on your gross margin. Adjust the margin, your monthly ad spend, and the net margin you want to earn, and see your break-even ROAS, the revenue you need to break even, and the target ROAS that leaves a profit. No opaque formulas: break-even ROAS depends only on your margin, not on industry averages. A tool to stop confusing ROAS with profitability.
Email Marketing ROI Calculator for Trades
Work out how much revenue your email list returns each year. Adjust your list size, emails sent per month, open rate, click rate and click-to-job conversion, plus your average job value and the cost of your email tool. You will see monthly and yearly revenue, the jobs it generates, the ROI over the tool cost and the revenue per subscriber. Transparent, directional model: email is the highest-ROI channel (Litmus and the DMA estimate around GBP 36 to 42 back per GBP 1 spent), but the numbers depend on your list, your offer and your cadence. Sending requires valid consent under PECR and the UK GDPR.
Google Ads ROI Calculator for Tradespeople
Work out the real return on your Google Ads spend before you commit a pound. Adjust your monthly budget, average CPC, landing-page conversion, lead-to-job close rate and average job value, and see the clicks, leads and jobs the campaign generates, the cost per lead, the cost per job, the net profit, and the ROAS (return per pound spent). A transparent model with no inflated numbers, using reference CPC and CPL figures from WordStream Google Ads benchmarks.
Local SEO Traffic & Leads Calculator
Calculate the extra traffic, leads and revenue your home-service business would gain by moving up the Google rankings for a local search. Adjust the monthly search volume, your current and target positions, and your conversion rates, and see the extra clicks per month, the extra leads and jobs, and the additional revenue per year. It uses an organic CTR-by-position curve drawn from public studies: directional, with no inflated numbers, and with a clear warning that the local pack behaves differently.
Marketing Budget Calculator for Tradespeople
Work out how much your trades business should invest in marketing based on annual turnover and your growth goal. Choose maintain position, grow, or aggressive growth, fine-tune the exact percentage, and see the recommended monthly and annual budget plus a suggested split across local visibility, paid ads, website, and reviews. Common guidance puts marketing spend at 5 to 10 percent of turnover, higher for newer or growing firms. Directional model, no inflated promises, just a sensible starting point you can adjust to your trade and your stage.
Missed-Call Revenue Calculator for Tradespeople
Calculate how much revenue your trades business loses every year to calls that go unanswered, and the return on an AI receptionist that answers 100% of them 24/7. Adjust your monthly calls, the percentage you miss, your average job value and your close rate, and see the revenue lost per month and per year, the net profit with AI, and the ROI. A transparent model with no inflated numbers: the response-speed effect is backed by Harvard research.
Google reviews target calculator for tradespeople
Find out how many Google reviews you need and at what pace to gather them so you can match your best-rated competitor and climb the Local Pack. Adjust the reviews you already have, your target, the jobs you close each month and the share of customers who leave a review when asked, and see the months to target, a realistic weekly pace and the ask rate you would need to get there in a year. Transparent model, no ranking promise: reviews are a meaningful signal but neither the only one nor a guarantee of position.
Sales Funnel Calculator for Tradespeople
See your sales funnel stage by stage: leads to quotes, quotes to booked jobs. Adjust your monthly leads, the conversion rate at each step and your average job value, and see revenue per month and per year, your overall conversion, and above all which of the two stages is your bottleneck. The tool calculates how much revenue you unlock by improving that weak stage by ten points, so you know where to invest before spending more to buy leads.
Speed-to-Lead Calculator for Tradespeople
Calculate how much revenue your trades business loses by responding slowly to leads, and how much extra revenue you would generate by responding in five minutes. Adjust your monthly leads, average job value, current response time and your close rate in the 5-minute window, and see the jobs you fail to book, your effective close rate today, and the extra revenue per month and per year. A directional model with an explicit decay curve and no inflated numbers: the response-speed effect is backed by Harvard Business Review.
Tax & admin
CIS, VAT reverse charge and refunds.
CIS refund calculator for subcontractors
Work out roughly how much CIS you will get back. Enter your labour turnover invoiced under the Construction Industry Scheme, the materials and expenses you can deduct, the 20% your contractors already took off and any other income, and the calculator estimates your taxable profit, your tax and National Insurance bill, and the refund (or balance owed) you should expect at Self Assessment. A transparent model using 2026/27 figures verified on gov.uk.
CIS deduction calculator for subcontractors
Work out the CIS deduction a contractor will withhold from your invoice under the Construction Industry Scheme, and the net payment you actually receive. Enter your total invoice, the materials portion, your CIS status (registered 20%, unregistered 30% or gross 0%) and your VAT position, and see the deduction, your labour amount, the net paid now and the effective rate. CIS is taken from labour only: materials are always paid in full, and you reclaim the deduction through Self Assessment.
VAT Reverse Charge Checker for Construction
Answer one question with confidence: do I charge VAT on this construction job, or does the domestic reverse charge apply? Set whether you and your customer are VAT registered, whether the customer is CIS registered, whether the work is within CIS scope, and whether the customer is the end user, then enter the net amount and VAT rate. The tool returns a clear verdict, the VAT to charge (zero under the reverse charge), the total invoice, and exactly what your invoice must say. Based on HMRC guidance in force since 1 March 2021.
Document generators
Quote, invoice and checklists as PDF.
Quote & Estimate Generator for UK Trades
Build a clean, professional quote or estimate as a PDF in minutes, with your logo, your VAT number, dynamic line items and the right VAT treatment. Add your company and client details, list the work, choose your VAT rate (20%, 5%, 0% or the domestic reverse charge for building and construction services), set a discount, a quote number, a date and how long the price is valid for, then print to PDF. A tidy quote signals a tidy job, and it is one of the cheapest ways to win more work without dropping your price.
How to Register as a Tradesman in the UK
A free, personalised checklist for setting up legally as a tradesperson in the UK. Enter your name, your trade and whether you will use subcontractors, and download a printable document with every registration in order: self-employment with HMRC, the Construction Industry Scheme, trade-specific schemes (Gas Safe Register for gas, a Part P competent person scheme for electrical work), insurance, VAT, accreditation and a CSCS card. It tells you which steps are a legal requirement and which are simply expected by clients and main contractors.
VAT-Compliant Invoice Generator for Construction
Build a VAT-compliant invoice for construction work in minutes, with the wording HMRC requires. Enter your supplier and customer details, add line items, choose the VAT treatment (standard, reduced, zero or the domestic reverse charge) and, if you are a subcontractor, the CIS deduction on labour. When you select the reverse charge the tool drops the VAT to zero and prints the required statement, "Reverse charge: Customer to account for the VAT to HMRC", showing the notional rate without adding it to the total. Save the result as a PDF.
