How to become a snagging inspector in the UK

What a snagging inspector actually does

A snagging inspector walks a newly built home, usually on or around completion, and records every item of workmanship or finish that falls short of the standard the builder signed up to. The output is a written report with photographs, which the client hands to the developer to get the items fixed.

A typical day is one property, sometimes two if they are on the same development. Two to four hours on site for a house depending on size, then the report. Some inspectors write it up that evening. The ones who have sorted their process send it from the car before they leave.

Most clients are buyers of new build homes. They have paid a lot of money, they do not know what a compliant plaster finish looks like, and they want someone on their side who does. A smaller share of work comes from developers and housing associations who want an independent pre-handover check across a batch of plots, and from landlords buying off plan. That second kind of client pays for volume and reliability rather than thoroughness on one house, and the report format has to suit them.

The job is not a hunt for things you dislike. Design choices are not defects. The developer built what was approved. Your credibility rests on listing things that are measurably wrong against a published standard and leaving the rest alone.

Background and what you actually need to know

In the UK there is no statutory licence for snagging inspectors and no protected title. Nobody checks your qualifications before you take a booking. That cuts both ways: it is easy to start, and it is easy to be the person whose report a site manager dismisses in thirty seconds.

The backgrounds that work are the ones where you have already stood in an unfinished house and known what good looks like. Trades, particularly plastering, joinery, tiling and second fix. Site management, which teaches you the sequence and where corners get cut. Building surveying and building control, which teach you the standards and how to write them down. A trade background alone tends to be strong in its own trade and weak elsewhere, so most people fill gaps deliberately.

What you must actually know, regardless of where you came from, is the warranty standard that applies to the plot and how its tolerances are measured. On most UK developments that means the NHBC Standards, or the technical manual of whichever warranty provider covers the site, such as LABC Warranty or Premier Guarantee. Those documents say how flat a plastered wall has to be, how much a door frame can be out of plumb, and what a tiled surface can deviate by. They say it as a measurement under a straightedge or a level over a stated length, and that is how you have to record it.

The credibility test is simple. A site manager reads your report with one question in mind: does this person know what they are talking about? A list that says “wall uneven” forty times fails that test. A list that says “plaster to left wall deviates 6 mm under a 2 m straightedge, exceeds tolerance, skim and redecorate” passes it, and every item after that gets read seriously. You get one chance to establish that on each site.

Qualifications and professional bodies

Because there is no licence, qualifications are about credibility with clients and with the people you argue with, not about permission to trade.

RICS is the chartered body for surveyors. Chartered status is a substantial route involving accredited degrees or assessed experience, and most snagging inspectors are not chartered. If you already are, it belongs at the top of your website. If you are not, it is not a barrier to the work.

The Residential Property Surveyors Association, RPSA, is a membership body for residential surveyors and inspectors and has been closely involved in how snagging inspections fit alongside the New Homes Quality Code. Its membership requirements and training are worth reading directly, because they will tell you what the sector currently treats as a reasonable minimum.

The New Homes Quality Code, run by the New Homes Quality Board, is the development that has changed the market most. Developers registered under the Code are required to allow a pre-completion inspection by a suitably qualified inspector on behalf of the buyer, following a defined checklist, before legal completion. That created a formal window for the inspection, where previously many developers refused access until keys were handed over. It has increased demand, and it has also raised the expectation that the inspector is competent, because the Code uses the words “suitably qualified” and buyers and developers both ask what that means in practice. Read the Code and the associated guidance yourself rather than relying on a summary, and check the current version, because the detail has been revised since it launched.

Alongside those, know the warranty providers’ standards well enough to cite the relevant section. NHBC publishes its Standards openly and most disputes on an NHBC-registered site come down to a paragraph in them.

Insurance and business setup

Clients, and increasingly developers under the Code, expect two policies. Professional indemnity covers you if a client says your report was negligent, for example that you missed something they later had to pay for. Public liability covers you if you damage the property or someone is injured because of something you did on site. Get both before the first paid job, and get quotes from brokers who understand surveying and inspection rather than a generic small business policy.

Sole trader or limited company is a question for an accountant, not a guide. Most people start as a sole trader for simplicity and revisit it once the income justifies the admin.

Write terms of engagement and have every client accept them before you attend. They should cover what the inspection includes and excludes, that it is visual and non-destructive, that you do not move furniture or lift floor coverings, that you inspect what is accessible on the day, that the report is for the client and not for third parties, and that it is not a structural survey or a certificate of compliance. State your fee, your cancellation terms, and what a re-inspection costs.

The report itself should carry a short version of those limitations on its cover or first page. Not as a wall of legal text, but as two or three sentences the reader will actually see.

Kit

The kit is modest and most of it fits in one bag. What matters is that you use the measuring tools on every wall rather than only when something looks wrong.

The phone is not an afterthought. It is the tool that turns the walk into the thing the client pays for. Site Audit runs on Android, works offline in a plot with no signal, needs no account, and lets you attach several captioned photographs to each snag, mark them up, and dictate the description while you are still standing in front of the defect.

Pricing a snagging survey

Advertised prices for a snagging survey in the UK commonly start in the low hundreds of pounds for a small house and go up from there. They scale with the number of bedrooms, because a five bedroom detached house takes twice as long as a two bedroom terrace, and with whether a re-inspection is included. Beyond that, price against the inspectors advertising in your own region rather than against a national figure, because rates vary a great deal between areas.

Structure the price rather than guessing it. A base fee for a small property, a step per additional bedroom, a separate line for the re-inspection, and a travel charge beyond a stated radius. Putting the re-inspection on its own line does two things: it lets a client who only wants the initial report pay less, and it makes clear that the second visit is real work rather than a courtesy.

Flats price differently to houses because there are no externals and usually fewer rooms, but communal areas and balconies can add time. Say what is included.

Do not compete purely on price in your first year. The buyers who pick the cheapest inspector are also the ones most likely to be unhappy with a shorter report, and the developers who deal with you will judge you on the quality of the document, not on what the client paid for it.

Finding your first clients

Nearly every new development of any size has a residents’ social media group, usually set up before the first plots complete. Buyers in those groups ask each other who to use for snagging. Being the inspector who is recommended there, with a sample report people can see, brings more work than any advertising. Join, be useful, answer questions honestly, and do not spam.

Being early on a development matters. The first buyer on a site who gets a thorough report becomes your reference for the next forty plots, and the site manager gets used to your format. Once you know a development well you inspect faster and your reports get more precise, because you have seen the same subcontractor make the same mistake in three plots already.

Conveyancers and mortgage brokers deal with new build buyers every week and are asked constantly who does snagging. A short introduction, a sample report and a reliable turnaround is enough to be the name they pass on. Local directories and a plain website with your area, your prices and a real sample report do the rest.

Ask every satisfied client for a review, and ask on the day the report lands rather than a month later. Reviews are the first thing the next buyer checks.

The report is the product

Nobody pays for the walk. They pay for the document. A client cannot see the two hours you spent on their staircase, but they can see whether the report is clear, whether the photographs show what you say they show, and whether the developer acted on it.

The structure that works is a cover with the property, the client, the date and your details; a summary table with every item numbered, its location, trade and priority; and then one entry per item with a precise location, a factual description with the measurement where one applies, the remedy expected, and at least two photographs. One wide shot showing where the defect is, one close shot showing what it is, both captioned.

Tone matters more than people expect. Write as a neutral observer recording what you found against the standard, not as an advocate writing for the buyer. A report that reads as fair gets more items fixed than one that reads as hostile, and it reflects on you when the client forwards it.

Producing that on the day is the difference between a business and a hobby. On paper you walk the house, take a few hundred photographs, and spend the evening matching them to notes. In Site Audit you record each snag as you find it: location, trade, description by dictation, as many captioned photographs as it needs, a circle drawn on the one where the defect is hard to see. The PDF is finished when the walk is, and there is a sample snagging report on this site showing the format.

The re-inspection report is the same register with items closed. Do not start a new document. Keep the original numbering, mark each item as closed with a date and a photograph of the fix, and leave the ones the developer disputes or has not done open with a note. The history of what was raised, what was fixed and what was argued about is what the client needs if anything ends up with the warranty provider.

This is honestly where the paid tier pays for itself. The free version handles one project fully, with a finished PDF that carries a small credit line in the footer. Pro, at A$29.99 one time with local pricing varying by country, removes the credit line, puts your own logo and business details on the cover, and gives you unlimited projects, one filtered report per trade so the developer can hand the plasterer only the plastering items, and CSV export for clients who want a spreadsheet. There is no subscription. Details are on the pricing page.

Mistakes people make in the first year

• Listing opinions. A tile colour you would not have chosen is not a snag. Every item on the list should point at a standard or a functional failure.
• No measurements. “Wall not flat” is an argument waiting to happen. The deviation under a straightedge is not.
• One photograph per snag. A close up of a scratch on white paint could be any of thirty walls. Always a locating shot and a detail shot.
• Sending the whole list as one block with no owner. A hundred items addressed to nobody get triaged by the site manager using their judgement rather than yours. Assign a trade to every item.
• No re-inspection. Signing off from photographs the developer sends is not an inspection. Go back, close each item yourself, and record the date.
• Overstating what you are. Do not describe the report as a certificate, a compliance check or a survey it is not. It will be quoted back at you.

The habits that make a good inspector are the same ones that make a good report, and they are learnable. For the writing itself, see the guide to writing a snagging report, and for what to check in each room and outside, the new build snagging checklist.
