Know what your home project will cost before you call anyone

Project
Used to adjust for regional prices.
Indicative range
£0 – £0
Indicative only, not a quote.
For homeowners
A budget you can plan around, in minutes
MAC Project Match is free for homeowners, with no account needed. It gives you an indicative range, not a quote, so you walk into the first conversation knowing roughly what is reasonable.
- Choose
Pick the project
Patios, fencing, driveways, kitchens, bathrooms, extensions and loft conversions. Start with the one on your mind.
- Describe
Answer a few plain questions
Size, finish, groundwork and where in the UK you are. No jargon, and nothing you would need a surveyor to tell you.
- Read
Get a realistic £ range
A low and a high figure, shown against a scale, so you can set a budget with room in it before you speak to anyone.
- Keep
Save it and compare
Keep your estimates in one place and revisit them as your plans change.
For builders and small contractors
From a rough scope to a costing you can defend
A subscription turns a project into a line-by-line breakdown. Labour, materials, plant, contingency and VAT sit in separate lines, so every total can be explained to the client.
- Itemised by trade and by cost type
- Projects saved and reopened, not rebuilt from scratch
- Clearly separate from the homeowner indicative estimate

Two tools, one clear line
An indicative estimate is not a professional costing
We keep the two apart on purpose. Homeowner ranges help you plan. Builder costings are built to be checked, line by line.
| Aspect | Homeowner estimate | Builder costing |
|---|---|---|
| Who it is for | Homeowners planning a project | Builders and small contractors |
| What you get | A realistic £ range | A line-by-line cost breakdown |
| Detail | Indicative, from a few questions | Labour, materials, plant, contingency, VAT |
| Use it to | Set a budget before calling builders | Price a job and explain the total |
| Cost | Free | Subscription |
Questions
Plain answers before you start
Is a MAC Project Match estimate a quote?
No. It is an indicative range to help you set a budget. Only a builder who has seen the site and the plans can give you a quote.
Do I need an account to get an estimate?
Homeowner estimates are free, with no sign-up needed to see a range. An account lets you save and revisit your estimates.
Which projects can I estimate?
Patios, fencing, driveways, kitchens, bathrooms, extensions and loft conversions.
What does the builder side add?
A subscription turns a project into an itemised breakdown covering labour, materials, plant, contingency and VAT.
Why a range and not one number?
Ground conditions, finishes and local labour rates move the final figure. A range is a more honest picture than a single price.
