THE SHORT ANSWER
A typical roofing project in the United Kingdom lands at GBP 5,200 to GBP 13,000 in 2026, with a midpoint near GBP 9,100. Gross margin on that midpoint is usually 25 to 35 percent, or GBP 2,300 to GBP 3,200. Against a modelled cost per lead of GBP 50 to GBP 100 and 4 to 6 exclusive leads per signed customer, acquisition consumes roughly 8.2 to 27.1 percent of the gross margin on one job.
Job value is the number every other commercial decision divides into, which is why roughly right beats precisely wrong. Below is a 2026 band for roofing projects in the United Kingdom and, more usefully, what happens when you divide it: margin on the midpoint job, and what winning that job costs before a single tool comes off the van.
Treat the width of the band as information rather than vagueness. The variables are surface area, whether the structure underneath needs work, and scaffolding access, and on top of them sits the market itself: in the United Kingdom, English-language auctions attract bidders from outside the country, which lifts click prices above what the local competitive density alone would justify.
The numbers, at a glance
Midpoint contract value: around GBP 9,100, inside a working band of GBP 5,200 to GBP 13,000 for roofing work in the United Kingdom
What is left after materials and labour: GBP 2,300 to GBP 3,200 of gross margin, being 25 to 35 percent of the midpoint contract
Lead spend per signed customer: GBP 250 to GBP 600, at 4 to 6 exclusive leads each costing GBP 50 to GBP 100
Margin consumed by acquisition: 8.2 to 27.1 percent of one job's gross margin, counting nothing from repeat or referral work
Where the roofing number comes from in the United Kingdom
Everything here is a complete installed job for a private household, excluding VAT and excluding competitively tendered work. Emergency repairs are excluded too: urgency prices on availability rather than on scope, and mixing the two produces an average that describes neither.
Inside that definition the spread comes from surface area, whether the structure underneath needs work, and scaffolding access. The United Kingdom is a market of roughly 68 million people, which is the pool every one of those quotes is written into.
Around GBP 5,200 for the simple version of this job on an accessible property.
Around GBP 9,100 for the version most quotes describe, including the upgrades customers ask for once they have seen the first price.
Around GBP 13,000 once scope, access or specification all move in the same direction.
Contract value against gross margin
Contract value is the figure contractors quote each other. Gross margin is the figure that pays wages. For roofing work in the United Kingdom the gap between them is 65 to 75 percent of the contract, so the GBP 9,100 midpoint leaves GBP 2,300 to GBP 3,200 behind.
Overheads, vehicles, insurance and the owner's own salary all come out of that, which means the money genuinely available to win the next customer is a fraction of the margin rather than the whole of it. Decide what share you will spend on acquisition before you look at any supplier price list. Established roofers tend to land between 10 and 20 percent of gross margin. Businesses in a deliberate growth phase run at 30 and accept that payback arrives on the second job.
What that means for what a lead is worth
A modelled exclusive lead for roofing work in the United Kingdom costs GBP 50 to GBP 100, and it takes 4 to 6 of them to sign one customer, because some enquiries never answer, some quotes lose and some projects are not ready. That puts the cost of a signed customer at GBP 250 to GBP 600 against gross margin of GBP 2,300 to GBP 3,200, so acquisition consumes 8.2 to 27.1 percent of the margin on a single job.
At the favourable end that is comfortably profitable on the first job alone. At the unfavourable end it works only if you convert above average, sell the fuller scope, or earn repeat and referral work. Which end you land on is mostly a function of how quickly you answer the phone, not how hard you negotiate the lead price.
Use your median job, not your average job
The mean is the wrong statistic for a contractor. One roofing project at the top of the band drags the average above anything you will quote next week, and a marketing budget built on it overspends quietly for months.
Take the median of your last twenty signed contracts instead. In a band of GBP 5,200 to GBP 13,000 the mean typically sits 8 to 15 percent above the median, because the distribution has a long right tail and no left one: there is a floor below which the job is not worth doing, and no ceiling above it. Budget against the median and let the large jobs be upside rather than assumption.
Zero rate VAT on energy-saving materials runs out in 2027
Installation of qualifying energy-saving materials in residential property in Great Britain is currently zero rated for VAT, with the relief scheduled to revert to 5 percent from April 2027. For solar, heat pumps and insulation that is a 20 percent difference against a standard-rated job in what the household pays. It is worth stating on the quote, both because it is a real reason to act now and because customers weighing an energy measure against general building work often do not realise the two are taxed differently. Confirm eligibility per measure rather than assuming it covers the whole contract.
Working capital at this contract value
Job value determines how much cash the business needs, not just how much it earns. On a GBP 9,100 project, materials and subcontract labour typically leave the account two to five weeks before the final invoice is paid, which is GBP 4,100 of exposure per job before anything goes wrong.
The remedy is structural rather than clever: a deposit near GBP 2,750 at order, a stage payment against delivery, and a final invoice on handover rather than thirty days after it. It also functions as a qualification tool. A household that cannot pay a deposit on a GBP 9,100 project is not a household that will pay the balance.
Some UK work carries a grant claimed by the installer, and most does not
The Boiler Upgrade Scheme pays GBP 7,500 towards an air source heat pump in England and Wales, and unusually it is claimed by the installer and shown as a deduction on the invoice, so the customer sees a net price from the first conversation. Insulation work reaches households through supplier-funded obligations instead. Everything else, which includes most replacement, fitting and improvement work, arrives with nothing attached. That split matters more than the individual amounts. In the grant-backed segment your quote is read as a net number and the scheme rules decide who is allowed to compete at all. In the unbacked segment you are quoting a full price into a household that has just been shown a subsidised one for a different job, and the answer to that is scope and certainty of date, not a discount.
Pricing per square metre works until it does not
A rate per square metre is a useful sanity check and a poor quoting method. It holds on a simple gable roof with easy access and breaks on anything with valleys, dormers, hips, chimneys or a conservatory in the way, because the detailing around each of those is measured in hours rather than area. One dormer can absorb a day of labour on a roof that priced at three days in total. Rate the area, then add the details as counted items with their own hours attached, and your quotes stop being a lottery you happen to win most weeks.
Repair, overhaul or replacement: the middle option is the trap
Roofing enquiries arrive as repairs and should convert as replacements. A patch on a roof past twenty-five years is a EUR 400 job that brings the customer back within two winters, usually annoyed. A full replacement is a EUR 9,000 job with a guarantee behind it. The dangerous middle is the partial strip: half a roof relaid to save money, which costs almost the same in scaffolding and access, carries the same risk and prices at two thirds. If the substrate is at end of life, quote the repair and the replacement side by side and let the customer choose with both numbers visible.
Turning this benchmark into your own figure
Start from invoices, not quotes: a median of twenty signed roofing contracts is worth more than any published average, including this one.
Take materials and installation labour out of each contract so you are working with margin rather than turnover.
Divide the number of enquiries you received by the number of customers you signed. That ratio, not the lead price, is what most contractors get wrong.
Price a signed customer by multiplying that ratio by the quoted lead price, then express it as a share of your median margin.
Re-run all five twice a year. Job values drift, conversion drifts faster, and a benchmark from eighteen months ago is a guess.
How these figures were built
These figures are a benchmark model, not a survey. They combine an industry base range observed across Western European home-improvement campaigns with a country multiplier for local auction pressure. Treat them as a band to negotiate against, not a quote. The band is an industry base range for roofing multiplied by a British construction cost index of 1.02, where the Benelux baseline is 1.00. Construction cost and advertising cost are modelled separately on purpose: cheap clicks and cheap labour do not reliably occur in the same market. Figures are modelled in euro and converted at 0.85 GBP per EUR 1, so the local number is indicative rather than a spot price.
How Flock Leads prices this
For comparison against the acquisition figures above, this is what Flock Leads charges for exclusive volume in this market:
Starter - 10 leads for EUR 750, which is EUR 75 per lead
Growth - 25 leads for EUR 1,750, which is EUR 70 per lead

Frequently asked questions
What is the average roofing job worth in the United Kingdom in 2026?
Modelled at GBP 5,200 to GBP 13,000 for a complete installed project for a private homeowner, excluding VAT, with a midpoint near GBP 9,100. The width is real: surface area, whether the structure underneath needs work, and scaffolding access all move the figure materially.
Is job value in the United Kingdom rising or falling in 2026?
Material prices have largely stabilised after the volatility of the early decade, while installation labour remains the tighter constraint across most of Western Europe. The practical effect is that job values drift upward slowly and the labour component grows as a share of each quote. Re-check your own median twice a year rather than trusting a published figure.
What gross margin should I expect on roofing work?
25 to 35 percent of contract value is the working band, which is GBP 2,300 to GBP 3,200 on the GBP 9,100 midpoint job. Below 25 percent you are either buying materials badly or quoting labour at a rate that does not cover a wet week.
Why do you use a different index for job value and lead cost?
Because they measure different things. Lead prices track how many installers are bidding in a local advertising auction. Job values track labour rates and material logistics. Poland has cheap clicks and cheap labour, Ireland has mid-priced clicks and very expensive labour, and a single multiplier would misprice both.
Does a higher job value make lead buying easier?
Usually, yes, because the lead price is close to fixed while the margin scales with the contract. At the GBP 9,100 midpoint, acquisition is 8.2 to 27.1 percent of gross margin. Raise the average job by a fifth and that percentage falls by roughly the same proportion without a single change to what you pay per lead.
