There is no single Google Ads budget that works for every UK builder. Start with your target qualified enquiries, local CPC, lead conversion rate, lead-to-job rate and acceptable acquisition cost. Then work backwards to a monthly budget.
Why This Topic Matters for UK Builders
UK private housing repair, maintenance and improvement activity is forecast to fall 8% in 2026 according to the CPA's Summer 2026 forecast. That makes efficient acquisition and measurement more important, but it does not create a universal advertising budget.
How Much Does Google Ads Cost for UK Builders?
Planning figures commonly fall around £1.50–£8 for trade/home-improvement searches, with specialist, urgent and competitive terms sometimes much higher. These are agency estimates, not audited UK builder benchmarks.
How Much Should a Builder Spend Per Month?
Treat these as planning ranges, not rules.
How Much Does a Builder Lead Cost?
There is no reliable audited UK-wide builder CPL. The article therefore compares cost per enquiry, qualified enquiry, survey, quote and booked job rather than treating raw CPL as the final KPI.
How to Calculate the Right Budget
Monthly budget = target qualified enquiries × cost per qualified enquiry.
Maximum affordable cost per booked job = gross profit per job × acceptable acquisition-spend percentage.
Illustration: £8,000 gross profit × 20% acquisition allocation = £1,600 maximum acquisition cost. This is a business assumption, not a market benchmark.
£500 vs £1,000 vs £2,000
£500/month ≈ £16.45/day; £1,000/month ≈ £32.89/day; £2,000/month ≈ £65.79/day when using Google's 30.4-day budgeting convention.
At £5 CPC, £1,000 buys about 200 clicks. At a 5% click-to-enquiry rate, that is about 10 enquiries. This is an illustration only.
Common Google Ads Mistakes for Builders
Setting the budget from a competitor blog; sending all traffic to the homepage; targeting too many services; using broad keywords without search-term control; optimising only for form submissions; ignoring calls; and increasing spend before proving lead quality.
Local Services Ads
Google's UK Local Services Ads documentation says eligible businesses can receive leads through calls and messages and pay for leads related to the services offered. Current UK eligibility includes General contractor services, subject to Google's eligibility and onboarding requirements.
Bottom Line
Do not publish a fixed 'correct' Google Ads budget for builders. Use the economics of the business to calculate the starting budget, then judge performance at qualified enquiry, booked-job and profit level.
Frequently asked questions
How much should a UK builder spend on Google Ads per month?
There is no single correct budget. Use your target qualified enquiries, local CPC, landing-page conversion rate, lead-to-job rate and acceptable acquisition cost to calculate a starting budget. UK agency sources commonly publish planning ranges from several hundred pounds to £2,000+ per month, with higher-value or competitive campaigns requiring more. These are not audited UK builder benchmarks.
What is a good Google Ads budget for builders?
A useful starting point is the smallest monthly budget that can generate enough qualified conversion data to make decisions. For many local builders, that may mean testing around £500–£1,000; established or higher-value campaigns may need £1,000–£2,000+; extensions, loft conversions and competitive London campaigns can require more. Treat these as planning ranges, not rules.
How much does a builder lead cost on Google Ads?
There is no reliable audited UK-wide builder CPL. UK agency sources report materially different ranges. Your own CPL depends on service, location, keyword mix, landing-page conversion rate and lead definition. Track cost per qualified enquiry and cost per booked job, not raw leads alone.
What is the average CPC for builders in the UK?
There is no single audited UK builder CPC. UK agency sources cited in this guide report broad planning ranges, often around £3–£8 for trade searches, with some higher-value or urgent services considerably above that. Actual CPC must be checked for the specific location and keywords.
Is Google Ads worth it for UK builders?
It can be, when the economics work. The correct test is whether qualified enquiries become profitable jobs at an acceptable acquisition cost. A campaign that produces cheap clicks but poor enquiries is not efficient.
How many leads can £1,000 of Google Ads generate for a builder?
It depends on CPC and conversion rate. At a £5 CPC, £1,000 buys about 200 clicks before other factors. At a 5% click-to-enquiry rate, that would be about 10 enquiries. This is an illustration, not a UK benchmark.
What is a good cost per lead for a builder?
A good CPL is one that fits the economics of your jobs. Calculate backwards from gross profit and your acceptable customer-acquisition spend. A £100 lead can be expensive for a small job and inexpensive for a high-margin extension if the lead quality and conversion rate support it.
How can builders generate qualified leads from Google Ads?
Use service-specific, high-intent keywords; tight location targeting; negative keywords; a dedicated landing page; clear qualification questions; call tracking; and conversion tracking beyond the form submission. Then feed qualified and booked-job outcomes back into the optimisation process.
