Design & Construct Contractors' Professional Indemnity Insurance in Bristol

Written for principal contractors, design-and-build (D&B) firms and specialist subcontractors carrying design responsibility across Bristol and the South West. Speak to a broker: 0117 325 0027 · info@apexinsurancebrokers.co.uk.

If you run a design-and-construct business in Bristol, your professional indemnity (PI) policy is no longer the box-tick it was a decade ago. The moment your contract makes you responsible for design — whether you employ in-house designers, novate a consultant, or rely on a specialist subcontractor's shop drawings — you have taken on a professional liability that a standard contractors' combined or public liability policy will not touch. On a live scheme in Temple Quarter, at Bristol Airport, or on a residential block in the city centre, that exposure can run to millions and outlast the project by many years.

Since the Building Safety Act 2022 and the Grenfell fallout reshaped the market, D&B contractors have found PI harder to buy, more expensive, and riddled with exclusions — fire safety, cladding, and building safety carve-outs are now the norm rather than the exception. This page explains what your PI actually needs to do, why Bristol's construction pipeline is driving demand for it, and how we place it.

Why Apex handles this

Bristol's construction pipeline is the reason this niche exists

Bristol has one of the most active regeneration pipelines outside London, and almost all of it is procured design-and-build. Temple Quarter and the St Philip's Marsh regeneration — one of the largest urban regeneration programmes in the country — is generating years of infrastructure, commercial and residential work. Add the sustained student and build-to-rent development around the city centre and Frome Gateway, the logistics and industrial expansion at Avonmouth and Severnside, and the continuing works programme at Bristol Airport, and you have a market where D&B contractors are routinely carrying design risk they may not have priced into their insurance.

The South West's construction base — from Bristol and Bath out to Weston, Gloucester and across the Severn into Newport and Cardiff — is dominated by mid-sized contractors and specialist trades (M&E, cladding and facades, structural steel, groundworks, modular) who take on "contractor's design portion" obligations. Under a JCT Design and Build contract, or where a consultant's appointment is novated to you, the design liability sits with the contractor. Your PI is what stands behind it. When a Bristol developer or funder asks for evidence of cover before you start on site, they are checking exactly that.

What "contractors' PI with design liability" actually needs to cover

Design-and-construct PI is not the same product an architect or engineer buys, and it is not the same as your public liability cover. Public liability responds to injury and physical damage; PI responds to financial loss arising from a negligent act, error or omission in the design or professional services you are contractually responsible for. On a typical D&B scheme, the pieces that matter are:

Fire safety, cladding and the Building Safety Act reality

This is the single hardest area of construction PI, and there is no point pretending otherwise. Following the Building Safety Act 2022, insurers have applied broad fire-safety and cladding exclusions across contractors' PI, and many impose an aggregate limit and sub-limit specifically for fire-safety-related claims. If you work on external walls, façades, insulation, compartmentation or anything touching the building safety regime, your cover on this front is likely to be narrower than you assume.

The Act also matters because of time. The retrospective limitation period under the Defective Premises Act 1972 was extended to 30 years for completed works and 15 years going forward, and dutyholder obligations under the new building safety regime for higher-risk buildings create long-tail liabilities. PI is written on a claims-made basis — it responds to claims notified during the policy period, not when the work was done — so continuity of cover, and run-off when you stop trading or wind down a company, is not optional. A gap in cover today can leave a claim in 2038 uninsured.

We will tell you honestly what the market can and cannot offer on fire safety for your particular trade and project mix, help you present the risk properly (documented design processes, third-party certification, competent-person schemes), and place the widest terms genuinely available — rather than selling you a policy that quietly excludes the work you actually do.

Collateral warranties, novation and the contract chain

Most PI problems on D&B schemes are not caused by bad design — they are caused by contract wording the contractor never had reviewed against the policy. A developer's collateral warranty that requires you to warrant fitness for purpose, or removes the net contribution clause, or extends liability beyond what your insurer will cover, transfers uninsured risk onto your balance sheet. On a Bristol regeneration scheme with multiple funders and a forward-sale to an institutional buyer, you can be asked to give a stack of these warranties, each subtly different.

Before you sign, we cross-check the key clauses — fitness for purpose, warranty periods, assignment, net contribution, and any deleterious-materials or fire-safety obligations — against your policy, and flag anything that would fall outside cover. If the wording cannot be softened, at least you go in knowing exactly where the uninsured exposure sits. That is a very different position from discovering it during a dispute.

How we place a Bristol D&B contractor's PI

A managed placement starts well before renewal, not in the final fortnight. We build a proper presentation of your business: your project book and split between traditional and design-and-build work, your in-house versus sub-let design, your quality and design-review processes, your fire-safety controls, and your claims history. A well-presented D&B risk gets seen by underwriters who would decline a thin proposal form out of hand.

We then approach the specialist construction PI markets — including Lloyd's and MGA capacity with real appetite for design-and-build — rather than relying on one insurer's off-the-shelf appetite. You get a clear comparison of limit, excess, fire-safety terms, aggregation and price, and a plain-English explanation of the exclusions that matter. And when a notification arises, it is handled by a director who understands the contract chain, not passed to a queue.

Related guides and sectors

D&B contractors often sit alongside the consultants they novate or subcontract to. If you are also mapping the wider professional-indemnity picture, these guides are a useful starting point:

Frequently asked

Isn't design liability already covered by my contractors' combined policy?

No. A contractors' combined or public liability policy responds to injury and physical damage. Professional indemnity responds to financial loss caused by a negligent act, error or omission in design or professional services. If your contract makes you responsible for any element of design, you need PI in addition to your combined cover.

We sub-let all our design — do we still need PI?

Usually yes. If your contract makes you responsible for the design (as most D&B and contractor's-design-portion arrangements do), you remain liable to the client even where you have sub-let the work. Your PI sits behind that liability. Relying solely on your subcontractor's PI leaves gaps — their limit, their exclusions and their continuity are outside your control.

What limit of indemnity do we need?

It depends on your contracts and project values. Building contracts and collateral warranties frequently specify a required limit — commonly £2m, £5m or £10m — and whether it must be per claim or in the aggregate. We match the limit and basis to your actual project book rather than a default figure, so one large loss cannot exhaust a year's cover.

Will PI cover fire-safety or cladding work?

This is the hardest area of the market. Since the Building Safety Act 2022, most insurers apply fire-safety and cladding exclusions or a restrictive aggregate sub-limit. Some cover is available depending on your trade, your controls and how the risk is presented. We will tell you honestly what is achievable for your business and place the widest terms genuinely on offer.

What about a collateral warranty that asks us to warrant fitness for purpose?

Standard PI covers negligence — the failure to exercise reasonable skill and care. A fitness-for-purpose or guaranteed-result obligation is usually excluded, so signing one transfers uninsured risk onto your business. We review warranty and appointment wording against your policy before you sign and flag anything that falls outside cover.

Why does continuity of cover matter so much?

PI is written on a claims-made basis, meaning it responds to claims notified during the policy period, not when the work was carried out. With limitation periods now extended to 15 years going forward (and 30 years retrospectively under the Defective Premises Act), a gap in cover — or no run-off when you cease trading — can leave a future claim uninsured. Maintaining continuous cover and arranging run-off is essential.

How these figures are produced

This guide is built from Apex's own market data: the premiums insurers have actually quoted and charged on professional indemnity risks we have handled. Each night that data is aggregated into anonymised rate bands by profession, fee income and limit of indemnity. No client information is published — a band only appears where it contains at least five separate records, and unusually high premiums are excluded so a single atypical risk cannot distort the guide.

The range shown spans the typical spread of recent market outcomes for similar risks. Individual quotes can fall outside it in either direction. Figures exclude insurance premium tax at 12%.

This calculator is not a quote and is not an offer of insurance or advice. Your actual premium depends on full underwriting of your business, including your activities, claims record and insurer appetite at the time.
