Areas we cover
Building in Boston
Boston is a historic market and port town in the Fens of south-east Lincolnshire, and one of the core towns we cover. The surrounding landscape is flat, low-lying and intensively farmed, and those surroundings make site-specific investigation important when planning work here — from drainage and groundworks to farm buildings on working rural sites.
Property in and around Boston ranges from older terraces and town-centre buildings to post-war housing, newer estates and isolated rural homes. Rural properties away from the mains sewer often rely on septic tanks or treatment plants, which is why we offer drainage and septic installations — with help on Environment Agency compliance and permits — within our Lincolnshire coverage.
We cover Boston together with nearby villages such as Kirton and the wider Fenland area. We offer free initial site visits and quote each job individually. A typical response or travel time to Boston has not been provided, and the number of jobs completed in the town has not been supplied, so we don't publish either figure.

Know before you build
Common building issues in Boston
High water tables and soft ground
Fenland ground around Boston is often low-lying, with soft silts, clays and peat in places and water close to the surface. Foundations, excavation support and drainage need to respond to those conditions, and specialist ground information may be needed before design is finalised.
Flood risk
Flood risk must be checked for the exact Boston address using the Environment Agency's mapping, rather than inferred from the town name. Where a risk applies, it can affect planning, floor levels and how new work is detailed. Check the flood position for the site early — it is far cheaper to design for it than to change a building afterwards.
Off-mains drainage
Rural homes without a sewer connection rely on their own systems. Discharge rules depend on the site, and a permit exemption cannot be assumed just because an old tank has been there for years. Replacements need checking against current rules.
Conditions vary by property. Check Environment Agency flood information and confirm planning requirements with the relevant local authority before relying on general area guidance.
Planning your project
Getting a Boston project ready to build
Start with the result you need
Before any drawings or prices, be clear about what the finished project must do for you. For a Boston home that might mean a larger kitchen, an extra bedroom or somewhere to park off the road. For a business or farm it might mean storage, vehicle access or space for staff. Writing down the essential requirements, the nice-to-haves and any fixed dates gives the free site visit a useful starting point and keeps later design decisions tied to the outcome rather than appearance alone.
Gather what you already have
Existing information can save time and avoid repeated work. Useful items include title plans, previous planning decisions, building control completion records, drainage plans, surveys and photographs of earlier alterations. If your Boston property has been extended before, records of that work help show what is already there and what the planning position may be. Missing information is not a problem in itself, but identifying it early means any investigation can be agreed before the scope is priced.
Check approvals before you commit
Planning permission, building regulations, HMO licensing and drainage permits are separate questions. One does not answer the others, and none should be assumed from a neighbour's project. Ranshaw Group manages planning applications and building control where required, but decisions remain with the relevant authorities. For a Boston project, checking the route before booking construction reduces the risk of designs needing revision or work stopping while an approval issue is resolved.
Compare quotes by scope, not total
Two prices for the same Boston project can cover very different work. Look at what each quotation includes: groundworks, drainage, removal of existing material, approvals management, finishes and any client-supplied items. Ask how changes will be agreed and when payments fall due. We offer free initial site visits and quote each job individually, with standard domestic payments staged so the final 5% is due on sign-off. A clear written scope is the most reliable basis for comparing builders.
Living and working nearby during the build
Building work affects the people around it. Before a Boston project starts, think about parking for deliveries and trades, where materials can be stored, whether neighbours should be told about the programme, and which rooms or areas must stay usable. For an occupied home or a working business, agree access and any temporary arrangements in advance. These practical details do not appear on a drawing, but discussing them before the start date makes the construction period far more predictable for everyone involved.
Our process
A clear route from first visit to sign-off
- 01
Free site visit
We come to the property, look at the site, access and existing buildings, and talk through what you want to achieve. Bring any drawings, surveys or previous approvals you have. The visit is free and carries no obligation, and it tells us what further information is needed before a meaningful quotation can be prepared.
- 02
Design & approvals
Where the project needs it, we develop the design and manage planning applications and building control. Authority decisions are not guaranteed. The approval route, supporting information and any effect on construction dates need to be established for the individual project.
- 03
Individual quotation
Every job is quoted individually — there are no fixed prices. Domestic payments are staged: 10% deposit on booking, 40% two weeks before the start date, 45% through the project and 5% on sign-off. Commercial staging can be adapted to development loans or lender schedules.
- 04
Coordinated construction
Groundworks, structure, services and finishes follow a sequence that matches the design and the required inspections. Our design-and-build capability covers all trades from groundworks to completion. The work and responsibilities need to be agreed for the individual project.
- 05
Sign-off & guarantee
For standard domestic projects, the final 5% is payable upon sign-off. All works carry an 18-month workmanship guarantee, plus matching manufacturer product warranties. Ask about the applicable guarantee terms. Keep the product and approval records for future maintenance.
Boston FAQs
Straight answers for Boston
Do you serve Boston?
Yes. Boston is one of the Lincolnshire areas we cover, alongside Lincoln, Grantham, Sleaford, North Hykeham and the other towns on our service-areas page. We're based at 10 Barnard House, LN4 2UT. Send us the site address and a short description of the work and we'll arrange a free initial visit.
How fast can you reach Boston?
A typical response or travel time to Boston has not been provided, so we don't promise one. Availability depends on the current programme of work. Call 07960 180466 during our hours — Monday to Saturday 6am–6pm, Sunday 8am–6pm — and we'll tell you honestly when a site visit can be arranged.
How much does building work cost in Boston?
There are no fixed prices or published rates: every Boston project is quoted individually, and free initial site visits are available. Access, ground conditions, specification and any approvals all affect the scope. Domestic payments are staged — 10% deposit, 40% two weeks before start, 45% during the work and 5% on sign-off — so you never pay the full amount up front.
Do you offer emergency call-outs in Boston?
An emergency or out-of-hours service has not been provided, and we don't advertise one. We focus on planned construction projects. If there is an immediate danger to people or property, contact the appropriate emergency service first. For urgent but non-emergency work, call 07960 180466 to discuss availability.
Is work in Boston guaranteed and insured?
Yes. All works carry our 18-month workmanship guarantee and we match manufacturer product warranties. We hold £10,000,000 public liability insurance. We do not currently hold trade-body accreditations such as FMB, CHAS or TrustMark, and we won't suggest otherwise.
Can you manage planning for a project in Boston?
Yes. We manage planning applications and building control where your project requires them. Decisions sit with the relevant local authority, so we never promise approval or a decision date. The approval route should be checked for the individual project before work starts.
Can you install a septic tank near Boston?
Yes. We install septic tanks and drainage around Boston and help with Environment Agency compliance and permits. Whether a permit is needed depends on the discharge and the general binding rules, so we check the site rather than assuming an exemption. Planning or building regulations may also apply.
Is building in the Fens around Boston more complicated?
It can be. Soft ground, high water tables and flood risk all affect foundation design, excavation and floor levels. These aren't reasons not to build — they're reasons to get ground information and the flood position checked before the design and quote are finalised.
