Questions
Frequently asked questions
How do I book a free site survey and written quote?
Start with our guide-price tool at /quote/ or send us your details through the contact page at /contact/, and we'll arrange a convenient time to visit. At the survey we measure up, look at access, the structure and any approvals the job may need, and talk through what you want. We then send a written quote setting out the agreed specification and a fixed price for that specification. The survey and quote are free, with no obligation to go ahead.
Which areas do you cover?
We cover the whole of the UK: England, Wales, Scotland and Northern Ireland. Every job is planned and managed by us and carried out by trades working under our contract. Because planning and building rules differ between the four nations, we check what applies to your property and your council before we quote. You can see more about coverage on our areas page at /areas/, or simply tell us your postcode when you get in touch.
Are the prices on your website quotes?
No. The prices on our website are guide ranges, including VAT at 20%, to help you plan a budget. Every home is different, and the final price depends on size, access, condition, the specification you choose and any approvals needed. After a free site survey, we confirm the price in writing as a fixed price for the agreed specification. Only that written quote is an offer to carry out the work.
How does payment work?
Payment stages are set out in your written quote before any work starts, so you know exactly what is due and when. We invoice each stage as it falls due and explain what it covers. If the work changes through an agreed variation, the change in price is confirmed in writing and added to the relevant stage. If anything about the payment terms is unclear, ask us before you sign and we will go through it with you.
Who carries out the work?
We plan and manage your project from survey to handover, and the work is carried out by trades working under our contract, so you have one point of contact and one agreement. Electrical and gas work is done by suitably registered and qualified people and certified on completion. We coordinate the trades, materials, inspections and approvals so the job runs in the right order.
Do you deal with planning permission and building control?
Yes. Before quoting, we check whether your project is likely to need planning permission, a certificate of lawfulness, Building Regulations approval or, in Scotland, a building warrant, along with any party wall notices in England and Wales. Where they are needed, we can arrange drawings, structural calculations and applications as part of the job, and we hand over the completion paperwork at the end. Any fees are shown in your quote.
